Embodiment
The effect of to make to architectural feature of the invention and being reached, has a better understanding and awareness, to preferableEmbodiment and attached drawing coordinate detailed description, are described as follows：
As shown in Figures 2 and 3, a kind of S-shaped cable laying component for photovoltaic plant waterborne, including swim on the water surfaceCase become floating platform 1, photovoltaic array 2 and cable mounting assembly 3, cable mounting assembly 3 are used for cable laying, equally swim in the water surfaceOn.Become as shown in Fig. 2, one end of cable mounting assembly 3 is installed on case on floating platform 1, as shown in figure 3, cable mounting assembly 3 is anotherOne end is installed on photovoltaic array 2.
As shown in Figure 1, in order to produce the phenomenon that cable is pullled between anti-floating body processed because of water level fluctuation (SEA LEVEL VARIATION),Here, cable mounting assembly 3 is S-shaped.
Cable mounting assembly 3 includes swimming in several floating bodies 4 of the water surface and carbon bellows 5, floating body 4 are used to support electricityCable, the quantity of floating body 4 can be 5-8.Cable 6 is installed with carbon bellows 5, carbon bellows 5 provides outer layer for cable 6 and protectsShield.Carbon bellows 5 is installed on several floating bodies 4, and 5-8 floating body 4 is arranged according to carbon bellows 5 from head to last row, and 5-8 floatingThe equal distribution in cable mounting assembly 3 of body 4 is put.
As shown in figure 4, two sidepieces of floating body 4 are provided with hollow support rails 7, hollow support rails 7 and 5 phase of carbon bellowsParallel, the direction at 7 both ends of hollow support rails and carbon bellows 5 are in the same direction.Steel wire rope 8, steel wire rope are installed with hollow support rails 78 one end is installed on case and becomes on floating platform 1, and the other end of steel wire rope 8 is installed on photovoltaic array 2.Here, the effect of steel wire rope 8There are two, first, each floating body 4 is stringed together to form overall structure, second, 8 length of steel wire rope, which is put, must be more than traditional floating bodyBetween length, formed 8 length of steel wire rope redundancy so that formed cable mounting assembly 3 S-shaped arrangement.In adjacent hollow branchTension spring 9 is mounted between strut 7 and tension spring 9 is sleeved on steel wire rope 8, i.e., will be formd between each floating body 4Elasticity is mutually of, the purpose so designed is when being swung between floating body 4, to avoid the collision between floating body 4.
In order to facilitate installation of the carbon bellows 5 on floating body 4, the upper surface of hollow support rails 7 can also be designed highIn the upper surface of floating body 4.Pipeline gag lever post 10, pipeline gag lever post are installed between two hollow support rails 7 of same floating body 410 on the cross section of pipeline gag lever post 10.As shown in fig. 6, carbon bellows 5 is installed on pipeline gag lever post 10 by anchor ear 11On.
In practical applications, with the fluctuation of the water surface, the S-shaped of cable mounting assembly 3 is also with the certain deformation of generation；TogetherReason, since photovoltaic plant waterborne is generally fixed with bank or with underwater fixed, if there is the situation of water level elevation rise, cableThe S-shaped of mounting assembly 3 can also produce certain deformation.And the both ends of cable mounting assembly 3 are separately mounted to case and become 1 He of floating platformOn photovoltaic array 2, during cable mounting assembly 3 produces deformation, cable mounting assembly 3 becomes 1 (photovoltaic array of floating platform with case2) if Hard link, then the junction that cable mounting assembly 3 becomes floating platform 1 (photovoltaic array 2) with case is easily caused to find to be broken.It is specialIt is not that water level fluctuation causes the deformation of cable mounting assembly 3, it is easier to cause pulling apart for 3 tie point of cable mounting assembly.In order toPrevent the junction that cable mounting assembly 3 becomes floating platform 1 (photovoltaic array 2) with case from finding to be broken, cable can also be installed groupPart 3 is become on floating platform 1 by sliding limit assembly installed in case, and similarly, cable mounting assembly 3 can also be by sliding limit assemblyOn photovoltaic array 2.
