技术领域technical field
本实用新型涉及风力发电机组领域，更具体地讲，本实用新型涉及一种用于风力发电机组的电缆护套。The utility model relates to the field of wind power generators, more specifically, the utility model relates to a cable sheath for wind power generators.
背景技术Background technique
为了使风力发电机组吸收更多的风能，通常，在风力发电机组进行发电过程中，利用偏航轴承进行偏航对风。In order to make the wind power generating set absorb more wind energy, generally, the yaw bearing is used to yaw against the wind during the process of generating power of the wind power generating set.
在进行偏航时，需要利用动力电缆和控制电缆传输电力和控制信号。在进行偏航过程中，动力电缆和控制电缆会随着机组偏航而旋转并向上提升，同时风力发电机组的塔架顶部摆动较大，造成从机舱到风力发电机组的塔筒的平台之间悬挂的动力电缆和控制电缆摆动较大，穿过平台的开口的动力电缆和控制电缆会与平台的开口的内壁以及设置在平台的开口中的平台钢圈不断刮擦，使得动力电缆和控制电缆出现磨损或刮伤，造成漏电，甚至会引起失火事故。When yawing, power cables and control cables need to be used to transmit power and control signals. During the yaw process, the power cables and control cables will rotate and lift up with the yaw of the unit, and at the same time, the top of the tower of the wind turbine will swing greatly, causing the gap between the platform from the nacelle to the tower of the wind turbine. The suspended power cables and control cables swing greatly, and the power cables and control cables passing through the opening of the platform will constantly scratch against the inner wall of the platform opening and the platform steel ring set in the platform opening, making the power cables and control cables Abrasion or scratches occur, causing electric leakage and even fire accidents.

以下，将结合图1至图3详细描述内护圈100和外护圈200的具体结构。Hereinafter, specific structures of the inner retainer 100 and the outer retainer 200 will be described in detail with reference to FIGS. 1 to 3 .
如图1所示，内护圈100可包括彼此分开的至少两个部分。例如，内护圈100可包括第一内护圈100a和第二内护圈100b。优选地，第一内护圈100a和第二内护圈100b可以为对称设置的两个半环形，两个半环形首尾相连以围成一个圆环形。然而，本实用新型不限于此。例如，内护圈100可包括彼此分开的三个或四个弧状部分。As shown in FIG. 1 , the inner retainer 100 may include at least two parts that are separated from each other. For example, the inner retainer 100 may include a first inner retainer 100a and a second inner retainer 100b. Preferably, the first inner retainer 100a and the second inner retainer 100b can be two semi-annular rings arranged symmetrically, and the two semi-annular rings are connected end to end to form a circular ring. However, the present invention is not limited thereto. For example, the inner retainer 100 may include three or four arcuate portions separated from each other.
第一凹槽121可形成在内护圈100的外壁上。可选地，可形成至少两个第一凹槽121，且第一凹槽121可均匀分布在内护圈100的外壁上。The first groove 121 may be formed on the outer wall of the inner retainer 100 . Optionally, at least two first grooves 121 may be formed, and the first grooves 121 may be evenly distributed on the outer wall of the inner retainer 100 .
如图1所示，外护圈200可包括可拆卸地连接的至少两部分。例如，外护圈200的至少两部分可通过第一连接件310彼此连接。As shown in FIG. 1 , the outer retainer 200 may include at least two parts that are detachably connected. For example, at least two portions of the outer retainer 200 may be connected to each other by a first connector 310 .
例如，外护圈200可包括第一外护圈200a和第二外护圈200b。优选地，第一外护圈200a和第二外护圈200b可以为对称设置的两个半环形，两个半环形首尾相连以围成一个环形。然而，本实用新型不限于此。例如，外护圈200可包括彼此分开的三个或四个弧状部分。为了描述方便，以外护圈200包括第一外护圈200a和第二外护圈200b两个部分为例进行描述。For example, the outer retainer 200 may include a first outer retainer 200a and a second outer retainer 200b. Preferably, the first outer retainer 200a and the second outer retainer 200b may be two semi-circular rings arranged symmetrically, and the two semi-circular rings are connected end to end to form a ring. However, the present invention is not limited thereto. For example, outer retainer 200 may include three or four arcuate portions that are spaced apart from one another. For the convenience of description, the outer retainer 200 includes two parts, the first outer retainer 200a and the second outer retainer 200b, as an example for description.
如图3所示，第二凹槽210可形成在第一外护圈200a的内壁上，并与第一凹槽121对应。风力发电机组的动力电缆1可穿过由第一凹槽121和/或第二凹槽210限定的容纳空间，并由内护圈100和外护圈200所夹紧，从而在进行偏航时，电缆护套随动力电缆1一起摆动，防止动力电缆1在风力发电机组的塔筒的平台4(如图1和图4所示)的开口内与平台4的内壁摩擦或与平台4内的平台钢圈5摩擦(如图1和图4所示)。可选地，可在每个容纳空间中设置三根或更多根动力电缆1。As shown in FIG. 3 , the second groove 210 may be formed on the inner wall of the first outer retainer 200 a and correspond to the first groove 121 . The power cable 1 of the wind power generating set can pass through the accommodation space defined by the first groove 121 and/or the second groove 210, and be clamped by the inner retainer 100 and the outer retainer 200, so that when yaw , the cable sheath swings together with the power cable 1 to prevent the power cable 1 from rubbing against the inner wall of the platform 4 in the opening of the platform 4 (as shown in Figure 1 and Figure 4 ) of the tower of the wind power generating set or rubbing against the inner wall of the platform 4 Platform steel ring 5 friction (as shown in Figure 1 and Figure 4). Optionally, three or more power cables 1 can be arranged in each accommodation space.
为了将动力电缆1夹紧，电缆护套还可包括用于调节内护圈100与外护圈200之间的间隙的夹紧构件。In order to clamp the power cable 1 , the cable sheath may further include a clamping member for adjusting the gap between the inner retainer 100 and the outer retainer 200 .
可选地，在外护圈200由多个部分形成的情况下，夹紧构件可以是将所述多个部分彼此可拆卸地连接的第一连接件。例如，在外护圈200由如上所述的第一外护圈200a和第二外护圈200b形成的情况下，夹紧构件可以是将第一外护圈200a和第二外护圈200b彼此可拆卸地连接的第一连接件310(如图1所示)。如图1所示，可在第一外护圈200a和第二外护圈200b的两端相应的位置设置通孔220。第一连接件310可穿透第一外护圈200a和第二外护圈200b的彼此相邻的通孔220，以将第一外护圈200a和第二外护圈200b彼此连接。可选地，第一连接件310可包括螺栓和螺母，可通过螺母的旋紧度来增大或减小内护圈与外护圈之间的夹紧力。Alternatively, where the outer retainer 200 is formed from a plurality of parts, the clamping member may be a first connector detachably connecting the plurality of parts to each other. For example, where the outer retainer 200 is formed of the first outer retainer 200a and the second outer retainer 200b as described above, the clamping member may be such that the first outer retainer 200a and the second outer retainer 200b are mutually accessible. The detachably connected first connecting piece 310 (as shown in FIG. 1 ). As shown in FIG. 1 , through holes 220 may be provided at corresponding positions at both ends of the first outer retainer 200 a and the second outer retainer 200 b. The first connecting member 310 may penetrate the through holes 220 adjacent to each other of the first outer retainer 200a and the second outer retainer 200b to connect the first outer retainer 200a and the second outer retainer 200b to each other. Optionally, the first connecting member 310 may include bolts and nuts, and the clamping force between the inner retainer and the outer retainer can be increased or decreased by tightening the nuts.
此外，根据本实用新型的示例性实施例的夹紧构件可包括用于连接内护圈100和外护圈200的第二连接件320(如图1所示)。例如，第二连接件320可沿护圈1000的径向将内护圈100和外护圈200彼此连接。例如，可在内护圈100上均匀地设置多个通孔140(如图2所示)，并在外护圈200的与通孔140对应的位置处均匀地设置多个通孔230(如图3所示)。第二连接件320可穿透通孔140和230，从而将内护圈100和外护圈200彼此连接。并通过第二连接件320的夹紧度来控制内护圈100与外护圈200之间的夹紧力。可选地，第二连接件320可以为螺栓和螺母，可通过螺母的旋紧来增大内护圈100与外护圈200之间的夹紧力。In addition, the clamping member according to the exemplary embodiment of the present invention may include a second connecting member 320 (as shown in FIG. 1 ) for connecting the inner retainer 100 and the outer retainer 200 . For example, the second connecting member 320 may connect the inner retainer 100 and the outer retainer 200 to each other in the radial direction of the retainer 1000 . For example, a plurality of through holes 140 (as shown in FIG. 2 ) can be uniformly arranged on the inner retainer 100, and a plurality of through holes 230 (as shown in FIG. 3). The second connection member 320 may penetrate through the through holes 140 and 230, thereby connecting the inner retainer 100 and the outer retainer 200 to each other. And the clamping force between the inner retainer 100 and the outer retainer 200 is controlled by the clamping degree of the second connecting member 320 . Optionally, the second connecting member 320 can be a bolt and a nut, and the clamping force between the inner retainer 100 and the outer retainer 200 can be increased by tightening the nut.
如上所述，通过第一连接件310和第二连接件320的连接和夹持作用，可调节内护圈100和外护圈200之间的夹紧力。As described above, the clamping force between the inner retainer 100 and the outer retainer 200 can be adjusted through the connection and clamping action of the first connecting member 310 and the second connecting member 320 .
应了解的是，在风力发电机组的偏航过程中，用于传输控制信号的控制电缆也会发生磨损。为了防止控制电缆发生磨损，现有技术中通常会另外地开发用于保护控制电缆的护套，这会导致生产成本较高。因此，为了降低生产成本，根据本实用新型的示例性实施例的电缆护套能够同时固定和保护控制电缆。以下，将参照图2描述根据本实用新型的示例性实施例的能够同时用于固定和保护控制电缆的内护圈100。It should be understood that during yawing of the wind turbine, the control cables used to transmit the control signals are also subject to wear. In order to prevent the control cable from being worn out, a sheath for protecting the control cable is usually additionally developed in the prior art, which leads to higher production costs. Therefore, in order to reduce the production cost, the cable sheath according to the exemplary embodiment of the present invention can simultaneously fix and protect the control cable. Hereinafter, an inner retainer 100 capable of simultaneously fixing and protecting a control cable according to an exemplary embodiment of the present invention will be described with reference to FIG. 2 .
根据本实用新型的示例性实施例，可在内护圈100的内壁上形成连接孔或连接突起，以用于固定控制电缆。According to an exemplary embodiment of the present invention, connection holes or connection protrusions may be formed on the inner wall of the inner retainer 100 for fixing the control cables.
根据本实用新型的一个实施例，如图2所示，内护圈100可包括内壳体110和外壳体120。内壳体110和外壳体120可彼此连接以限定空腔130。根据本实用新型的实施例，如图2所示，可在内壳体110上形成多个第一通孔111，以形成连接孔。According to an embodiment of the present invention, as shown in FIG. 2 , the inner retainer 100 may include an inner shell 110 and an outer shell 120 . The inner case 110 and the outer case 120 may be connected to each other to define a cavity 130 . According to an embodiment of the present invention, as shown in FIG. 2 , a plurality of first through holes 111 may be formed on the inner casing 110 to form connection holes.
例如，可将绑扎带3穿过第一通孔111，从而将控制电缆2绑扎在内壳体110上(如图1所示)。例如，每个绑扎带可绑扎三根控制电缆2。因此，根据本实用新型的示例性实施例，通过设置第一通孔111，可同时固定控制电缆2。此外，通过在内护圈100中设置腔体130，与内护圈100中未形成腔体130相比，还可降低内护圈100的重量，不仅节省成本，还可防止护圈1000由于重力而从电缆上滑落。For example, the binding strap 3 can be passed through the first through hole 111 to bind the control cable 2 on the inner casing 110 (as shown in FIG. 1 ). For example, each strap can bind three control cables 2 . Therefore, according to the exemplary embodiment of the present invention, by providing the first through hole 111, the control cable 2 can be fixed at the same time. In addition, by providing the cavity 130 in the inner retainer 100, compared with the inner retainer 100 without the cavity 130, the weight of the inner retainer 100 can be reduced, which not only saves cost, but also prevents the retainer 1000 from being damaged by gravity. and slip off the cable.
另外，根据本实用新型的示例性实施例，作为可选方案，可以在内壳体110的内壁上形成连接突起，用于固定控制电缆。所述连接突起可以是设置在内护圈100的内壁上的钩状构件或环状构件(未示出)。例如，可利用绑扎带将控制电缆绑扎在钩状构件上。或者，可直接使控制电缆穿过环状构件，从而将其固定在环状构件中。In addition, according to an exemplary embodiment of the present invention, as an optional solution, a connection protrusion may be formed on the inner wall of the inner housing 110 for fixing the control cable. The connection protrusion may be a hook member or a ring member (not shown) provided on the inner wall of the inner retainer 100 . For example, the control cables may be bound to the hook members with binding ties. Alternatively, the control cables may be passed directly through the ring member, thereby securing it in the ring member.
应理解的是，可不在电缆护套上设置绑扎带，而是在利用电缆护套固定控制电缆2时利用绑扎带穿过第一通孔111、钩状构件或环状构件来固定控制电缆2。It should be understood that the binding tape may not be provided on the cable sheath, but when the control cable 2 is fixed by using the cable sheath, the binding tape is used to pass through the first through hole 111, the hook member or the ring member to fix the control cable 2 .
如上所述，根据本实用新型的示例性实施例，通过在内护圈100的内壁上设置用于固定控制电缆2的连接孔或连接突起，不仅能够将控制电缆2与动力电缆1分开，还能够利用同一个电缆护套同时保护动力电缆1和控制电缆2，从而可节省因单独生产用于保护控制电缆2的护套所需的成本。As mentioned above, according to the exemplary embodiment of the present utility model, by providing the connection hole or the connection protrusion for fixing the control cable 2 on the inner wall of the inner retainer 100, not only the control cable 2 can be separated from the power cable 1, but also The same cable sheath can be used to simultaneously protect the power cable 1 and the control cable 2 , thereby saving the cost required for separately producing the sheath used to protect the control cable 2 .
根据本实用新型的示例性实施例，在内护圈100的内壳体110上还可设置有开口112。例如，可沿内护圈100的轴向延伸地形成开口112。可选地，在内护圈100由多个部分形成时，可在每个部分上均形成开口112。According to an exemplary embodiment of the present invention, an opening 112 may also be provided on the inner casing 110 of the inner retainer 100 . For example, the opening 112 may be formed extending in the axial direction of the inner retainer 100 . Alternatively, where the inner retainer 100 is formed from multiple parts, the opening 112 may be formed in each part.
由于设置了开口112，在利用夹紧构件(例如，第一连接件310和第二连接件320)对内护圈100和外护圈200进行夹紧时，可提高内护圈100变形的自由度，从而可提高内护圈100和外护圈200之间的夹紧力，防止因夹持不牢而导致的护圈1000从动力电缆1上脱落。Due to the provision of the opening 112, when the inner retainer 100 and the outer retainer 200 are clamped by clamping members (for example, the first connecting member 310 and the second connecting member 320), the freedom of deformation of the inner retainer 100 can be improved. Therefore, the clamping force between the inner retainer 100 and the outer retainer 200 can be increased to prevent the retainer 1000 from falling off the power cable 1 due to loose clamping.
此外，根据本实用新型的示例性实施例，内护圈100和外护圈200可由阻燃有机材料形成。在这种情况下，可更好地保护动力电缆1和控制电缆2。同时，还可防止内护圈100和外护圈200在不断摩擦过程中由于温度过高而燃烧。例如，内护圈100和外护圈200的材料可以是阻燃型尼龙66。In addition, according to an exemplary embodiment of the present invention, the inner retainer 100 and the outer retainer 200 may be formed of a flame-retardant organic material. In this case, the power cable 1 and the control cable 2 are better protected. At the same time, it can also prevent the inner retainer 100 and the outer retainer 200 from burning due to excessive temperature during continuous friction. For example, the material of the inner retainer 100 and the outer retainer 200 may be flame-retardant nylon 66.

以下，将参照图4至图8描述根据本实用新型的另一示例性实施例的电缆护套。Hereinafter, a cable sheath according to another exemplary embodiment of the present invention will be described with reference to FIGS. 4 to 8 .
如图4所示，根据本实用新型的另一示例性实施例的电缆护套可包括两个护圈1000。此外，根据本实用新型的另一示例性实施例的电缆护套还可包括多根支撑杆400。两个护圈1000同轴设置，并沿轴向方向通过多根支撑杆400相互连接并间隔开预定距离。支撑杆400可设置在外护圈200的外周。优选地，多根支撑杆400可均匀地设置在外护圈200的外周。As shown in FIG. 4 , a cable jacket according to another exemplary embodiment of the present invention may include two retaining rings 1000 . In addition, the cable sheath according to another exemplary embodiment of the present invention may further include a plurality of support rods 400 . The two retaining rings 1000 are arranged coaxially, are connected to each other by a plurality of support rods 400 in the axial direction and are spaced apart by a predetermined distance. The support rod 400 may be disposed on the outer periphery of the outer retainer 200 . Preferably, a plurality of support rods 400 may be uniformly disposed on the outer periphery of the outer retainer 200 .
两个护圈1000中的每个可具有如图1-3所示的结构，因此为了避免重复，将不对其作进一步描述。Each of the two retaining rings 1000 may have a structure as shown in FIGS. 1-3 , and thus will not be further described in order to avoid repetition.
如图3所示，可在外护圈200的外壁上设置(例如，均匀地设置)多个凸缘240。例如，凸缘240可从外护圈200的外壁沿护圈1000的径向向外延伸。可在凸缘240上设置多个第二通孔241。支撑杆400可穿过多个第二通孔241并与外护圈200固定连接。As shown in FIG. 3 , a plurality of flanges 240 may be provided (eg, uniformly provided) on the outer wall of the outer retainer 200 . For example, the flange 240 may extend radially outward from the outer wall of the outer retainer 200 along the radial direction of the retainer 1000 . A plurality of second through holes 241 may be provided on the flange 240 . The support rod 400 can pass through the plurality of second through holes 241 and be fixedly connected with the outer retainer 200 .
根据本实用新型的示例性实施例，电缆护套还可包括多个套管500。如图8所示，套管500可具有穿过轴心的通孔510，支撑杆400可从通孔510穿过。多个套管500可分别可转动地套设在多根支撑杆400上，并位于两个护圈1000之间。套管500的两端可分别与上面的护圈1000的底表面和下面的护圈1000的顶表面可隔开预定间隙，以使套管500可自由地转动，而不受护圈1000的阻挡。According to an exemplary embodiment of the present invention, the cable sheath may further include a plurality of sleeves 500 . As shown in FIG. 8 , the sleeve 500 may have a through hole 510 passing through the shaft, and the support rod 400 may pass through the through hole 510 . A plurality of sleeves 500 can be respectively rotatably sleeved on a plurality of support rods 400 and located between two retaining rings 1000 . Both ends of the sleeve 500 can be separated from the bottom surface of the upper retainer 1000 and the top surface of the lower retainer 1000 respectively by a predetermined gap, so that the sleeve 500 can rotate freely without being blocked by the retainer 1000 .
可在支撑杆400的两端分别设置两个固定件，例如，可在支撑杆400的上端设置第一固定件410和第二固定件420，并可在支撑杆400的下端设置第三固定件430和第四固定件440。可使上面的护圈1000的凸缘240固定在第一固定件410和第二固定件420之间，可使下面的护圈1000的凸缘240固定在第三固定件430和第四固定件440之间。Two fixing parts can be respectively arranged at the two ends of the supporting rod 400, for example, a first fixing part 410 and a second fixing part 420 can be arranged at the upper end of the supporting rod 400, and a third fixing part can be arranged at the lower end of the supporting rod 400 430 and the fourth fixing piece 440. The flange 240 of the upper retainer 1000 can be fixed between the first fixing part 410 and the second fixing part 420, and the flange 240 of the lower retaining ring 1000 can be fixed between the third fixing part 430 and the fourth fixing part Between 440.
此外，套管500还可包括设置在其两端处的容纳部520。两个容纳部520可分别容纳第一固定件410和第三固定件430。支撑杆400的两端可设置有外螺纹，第一固定件410、第二固定件420、第三固定件430和第四固定件440可以是螺母，从而通过螺纹配合使支撑杆400的两端分别与护圈1000固定连接。In addition, the sleeve 500 may further include receiving parts 520 provided at both ends thereof. The two receiving parts 520 can respectively accommodate the first fixing part 410 and the third fixing part 430 . The two ends of the support rod 400 can be provided with external threads, and the first fixing part 410, the second fixing part 420, the third fixing part 430 and the fourth fixing part 440 can be nuts, so that the two ends of the supporting rod 400 can be screwed together. They are respectively fixedly connected with the retaining ring 1000.
根据本实用新型的示例性实施例，通过在支撑杆400上设置套管500并使套管500能够围绕支撑杆400转动，在套管500与平台钢圈5接触时，套管500会发生转动，从而能够显著减小套管500与平台钢圈5的摩擦，并且可对支撑杆400起到保护作用。此外，即使套管500损坏，也能够容易地更换套管500。According to an exemplary embodiment of the present invention, by arranging the sleeve 500 on the support rod 400 and enabling the sleeve 500 to rotate around the support rod 400, when the sleeve 500 is in contact with the platform steel ring 5, the sleeve 500 will rotate , so that the friction between the casing 500 and the platform steel ring 5 can be significantly reduced, and the support rod 400 can be protected. Furthermore, even if the sleeve 500 is damaged, the sleeve 500 can be easily replaced.
可选地，套管500可由阻燃有机材料形成。因此，可防止套管500在不断摩擦过程中由于温度过高而燃烧。例如，套管500的材料可以是阻燃型尼龙66。Alternatively, sleeve 500 may be formed from a flame retardant organic material. Therefore, it is possible to prevent the bushing 500 from burning due to excessive temperature during constant friction. For example, the material of the sleeve 500 may be flame-retardant nylon 66.
如图4所示，在风力发电机组的偏航过程中，电缆会与电缆护套一起向上提升，进入风力发电机组的塔筒的平台4的开口。平台4的开口中设置有平台钢圈5。如果电缆护套的高度h过小，则电缆护套对电缆的覆盖面过小，那么未被电缆护套覆盖的电缆会受到平台钢圈5的磨损。因此，需要加大电缆护套的总高度。As shown in Fig. 4, during the yaw process of the wind power generating set, the cable will be lifted upward together with the cable sheath, and enter the opening of the platform 4 of the tower of the wind generating set. A platform steel ring 5 is arranged in the opening of the platform 4 . If the height h of the cable sheath is too small, the coverage of the cable sheath on the cables is too small, and the cables not covered by the cable sheath will be worn by the platform steel ring 5 . Therefore, the overall height of the cable sheath needs to be increased.
然而，如果单纯加大电缆护套的内护圈100和外护圈200的高度，则会使得电缆护套的体积较大，导致电缆护套的自重较重，使得电缆护套容易从动力电缆脱落。However, if the height of the inner retainer 100 and the outer retainer 200 of the cable sheath is simply increased, the volume of the cable sheath will be larger, resulting in a heavier self-weight of the cable sheath, which makes the cable sheath easy to dislodge from the power cable. fall off.
根据本实用新型的示例性实施例，通过同轴地设置两个护圈1000，并设置沿轴向方向连接两个护圈1000并使两个护圈1000间隔开预定距离的支撑杆400，可将对电缆的保护长度加大为L，这里L可以远大于h。这样不仅能够加大对电缆的保护面积，还可显著减小电缆护套的自重，从而可防止电缆护套从电缆上脱落。According to an exemplary embodiment of the present invention, by coaxially arranging two retaining rings 1000, and providing a support rod 400 connecting the two retaining rings 1000 in the axial direction and separating the two retaining rings 1000 by a predetermined distance, it is possible to Increase the protection length of the cable to L, where L can be much greater than h. This can not only increase the protection area of the cable, but also significantly reduce the weight of the cable sheath, thereby preventing the cable sheath from falling off from the cable.
虽然，为了加大对电缆的保护面积，可以通过加长支撑柱400的长度，但是，也可以设置更多个护圈1000，并在相邻的护圈1000之间设置支撑柱来加长保护长度L。在这种情况下，可以在支撑柱的中部设置外螺纹，用于与设置在中间位置的护圈1000连接。Although, in order to increase the protection area of the cable, the length of the supporting column 400 can be lengthened, but more retaining rings 1000 can also be provided, and supporting columns can be set between adjacent retaining rings 1000 to lengthen the protective length L . In this case, an external thread may be provided in the middle of the support column for connecting with the retainer 1000 provided in the middle.
应理解的是，虽然以上作为示例描述了利用根据本实用新型的电缆护套来保护动力电缆和控制电缆，以防止动力电缆和控制电缆受到风力发电机组的塔筒的平台的内壁或平台内的钢圈的摩擦，但根据本实用新型的电缆护套的用途不限于此。例如，在没有平台的位置处，可使用根据本实用新型的电缆护套作为将动力电缆隔开的隔环，以防止多根动力电缆混在一起，不利于动力电缆的有效散热。因此，在将根据本实用新型的电缆护套作为隔环时，可保证动力电缆的有效散热，提高风力发电机组运行的稳定性。It should be understood that, although the above describes using the cable sheath according to the present invention as an example to protect power cables and control cables, so as to prevent the power cables and control cables from being damaged by the inner wall of the platform of the tower of the wind power generating set or within the platform. The friction of the steel ring, but the use of the cable sheath according to the present invention is not limited thereto. For example, at the position where there is no platform, the cable sheath according to the present invention can be used as a spacer ring separating the power cables, so as to prevent multiple power cables from mixing together, which is not conducive to the effective heat dissipation of the power cables. Therefore, when the cable sheath according to the utility model is used as a spacer ring, the effective heat dissipation of the power cable can be ensured, and the stability of the operation of the wind power generating set can be improved.
如上所述，根据本实用新型的示例性实施例，通过由内护圈100和外护圈200围成容纳空间，并在内护圈100的内壁上形成连接孔或连接突起，可同时固定动力电缆1和控制电缆2，并将控制电缆1和控制电缆2间隔开，而无需为控制电缆2设置另外的护套。因此，可节省因单独生产用于固定控制电缆2的护套所需的成本。As mentioned above, according to the exemplary embodiment of the present invention, by forming the accommodation space surrounded by the inner retainer 100 and the outer retainer 200, and forming a connection hole or a connection protrusion on the inner wall of the inner retainer 100, the power can be fixed at the same time. Cable 1 and control cable 2, and separate control cable 1 and control cable 2, without providing additional sheath for control cable 2. Therefore, the cost required for separately producing the sheath for fixing the control cable 2 can be saved.
此外，根据本实用新型的示例性实施例，可在内护圈100的内壳体110上形成开口112，因此可提高内护圈100变形的自由度，从而可提高内护圈100和外护圈200之间的夹紧力。In addition, according to an exemplary embodiment of the present invention, the opening 112 can be formed on the inner casing 110 of the inner retainer 100, so that the degree of freedom of deformation of the inner retainer 100 can be improved, thereby improving the inner retainer 100 and the outer retainer. Clamping force between circles 200.
另外，根据本实用新型的示例性实施例，通过在两个护圈1000之间设置支撑杆400从而形成一个加长的电缆护套，可降低电缆护套的自重，从而防止电缆护套从电缆上脱落。In addition, according to the exemplary embodiment of the present invention, by providing the support rod 400 between the two retaining rings 1000 to form an elongated cable sheath, the self-weight of the cable sheath can be reduced, thereby preventing the cable sheath from falling from the cable. fall off.
尽管已经参照其示例性实施例具体描述了本实用新型的示例性实施例，但是本领域的技术人员应该理解，在不脱离权利要求所限定的本实用新型的精神和范围的情况下，可以对其进行形式和细节上的各种改变。Although the exemplary embodiments of the present invention have been specifically described with reference to the exemplary embodiments thereof, those skilled in the art should understand that, without departing from the spirit and scope of the present invention defined by the claims, the It undergoes various changes in form and detail.
