技术领域technical field
本发明属于涉及一种用于消除通风管道噪音的外套结构及其实施方法。The invention belongs to a jacket structure for eliminating the noise of a ventilation duct and an implementation method thereof.
背景技术Background technique
通风设备被广泛地应用于各种领域，例如为工业、建筑施工的加热、通风以及制冷；生活住宅中冰箱、空调等的空气交换、电子设备冷却等诸多方面。在上述场景中，一方面，空气在风机带动下通过现有的流通路径时会产生中高频噪音，另一方面，通风管道或其他机械部件也会因为震动或摩擦而产生低频噪音。若通风设备处于相对封闭且空旷的环境中其噪音会被明显放大，形成强烈且持续的环境噪音；而当通风换气设备架设于居住区附近时，亦对市环境质量造成不良影响。因此，如何有效地降低噪音、同时兼顾中高频噪音和低频噪音的影响，是目前亟需解决的问题。Ventilation equipment is widely used in various fields, such as heating, ventilation and cooling for industry and building construction; air exchange for refrigerators, air conditioners, etc. in living houses, cooling of electronic equipment, and many other aspects. In the above scenario, on the one hand, air will generate medium and high frequency noise when it passes through the existing circulation path driven by the fan; on the other hand, ventilation pipes or other mechanical components will also generate low frequency noise due to vibration or friction. If the ventilation equipment is in a relatively closed and open environment, the noise will be significantly amplified, forming strong and continuous environmental noise; and when the ventilation equipment is erected near the residential area, it will also have a negative impact on the urban environmental quality. Therefore, how to effectively reduce noise while taking into account the influence of medium-high-frequency noise and low-frequency noise is an urgent problem to be solved at present.
现有技术中，一方面，高频噪音主要靠空气传播，因此通常采用中空结构、通孔结构等来抑制中高频噪音；而为了消除中低频噪音，现有技术中通常采用由隔音材料组成的一层或多层隔音层。因此，为了同时阻消高低频噪声，现有技术通常将上述两种方式组合使用，如在通风管道外壁设置噪音阻消外套结构。然而上述噪音阻消方式均是“治标而不治本”，分析噪音产生的源头主要是来自通风管道或其他机械部件的震动，因此如何采用简单有效的方式，使得在采用高低频噪音阻消措施的同时，兼顾对通风管道或其他机械部件的减震措施，是目前所面临的一个问题。In the prior art, on the one hand, high-frequency noise is mainly transmitted by air, so hollow structures, through-hole structures, etc. are usually used to suppress mid- and high-frequency noise; and in order to eliminate mid- and low-frequency noise, sound-insulating materials are usually used in the prior art. One or more layers of sound insulation. Therefore, in order to simultaneously suppress high and low frequency noises, the prior art generally uses the above two methods in combination, such as providing a noise-absorbing jacket structure on the outer wall of the ventilation duct. However, the above-mentioned noise suppression methods are all "fixing the symptoms but not the root cause". The source of noise analysis is mainly from the vibration of ventilation ducts or other mechanical parts. At the same time, taking into account the shock absorption measures for ventilation ducts or other mechanical parts is a problem that is currently faced.
另一方面，现有的噪音阻消外套结构的施工方法主要包括：(1)嵌套连接，其需要将外套内径减小以增加外套与通风管道外壁的紧密接触达到减震的效果，但将通风管道嵌套在外套时其阻力会大大增加，施工难度也大大增加；(2)拼接连接，其需要额外的连接件用以连接可分离的外套结构，但连接件由于长期受力，其可靠性可能会受影响而导致外套结构损坏，另外为了达到支撑缓震的效果其外套内径也要减小，因此连接件扣合时阻力也较大。On the other hand, the existing construction methods of the noise damping jacket structure mainly include: (1) nested connection, which requires reducing the inner diameter of the jacket to increase the close contact between the jacket and the outer wall of the ventilation duct to achieve the effect of shock absorption, but the When the ventilation pipe is nested in the jacket, its resistance will be greatly increased, and the construction difficulty will also be greatly increased; (2) Splicing connection, which requires additional connectors to connect the detachable jacket structure, but the connectors are not reliable due to long-term stress. In addition, in order to achieve the effect of supporting and cushioning, the inner diameter of the jacket should also be reduced, so the resistance when the connector is fastened is also relatively large.
专利TWM506940U(文献1)公开了一种风管结构改良的方案，其通利用在内外防火管中加入数层密度不同的隔温层用以达到吸收噪音、保温的效果，同时这些隔温材料也可以达到支撑缓震的效果。然而文献1的上述方案仍然存在诸多问题：一是文献1的装置没有设置中空结构无法隔离中高频的噪音；二是其施工方式利用传统的嵌套方法导致其施工阻力较大、难度较高。Patent TWM506940U (document 1) discloses a scheme for improving the structure of air ducts. It generally uses several layers of heat insulation layers with different densities in the inner and outer fireproof pipes to achieve the effects of noise absorption and heat preservation. At the same time, these heat insulation materials are also It can achieve the effect of supporting and cushioning. However, there are still many problems in the above scheme of Document 1: first, the device in Document 1 does not have a hollow structure and cannot isolate medium and high frequency noise; second, its construction method uses the traditional nesting method, resulting in greater construction resistance and difficulty.
专利JP2017057745A(文献2)公开了一种排气管罩结构的技术方案，其利用在环形排气管外部覆盖成对的半圆形盖体并形成间隙来抑制因震动而产生的噪音。然而文献2的上述方案仍然存在诸多问题：一是文献2中未采用隔音材料无法有效抑制中低频的噪音；二是文献2的盖体采用硬性材料，其支撑减震的效果差；三是文献2的盖体通过拼接连接，由于盖体采用硬性材料连接件连接时阻力较大，且其连接件可能由于长期受力而可靠性差。文献2无法兼顾中高频噪音和低频噪音，也未能解决现有技术中外套结构实施方式所存在的问题。Patent JP2017057745A (document 2) discloses a technical solution of an exhaust pipe cover structure, which uses a pair of semicircular covers on the outside of the annular exhaust pipe to form a gap to suppress the noise generated by vibration. However, there are still many problems in the above-mentioned scheme of Document 2: First, the sound insulation material in Document 2 cannot effectively suppress low-frequency noise; The cover body of 2 is connected by splicing, because the resistance of the cover body is relatively large when the hard material connector is used for connection, and the connector may have poor reliability due to long-term stress. Document 2 cannot take into account both medium and high-frequency noise and low-frequency noise, and also fails to solve the problems existing in the implementation of the jacket structure in the prior art.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and should not be construed as indicating or implying relative importance.
参见图1，为本发明外套结构的纵剖立体图，所述外套结构包括内侧壁7和外侧壁8，在所述内侧壁7与外侧壁8之间的空隙填充有隔音材料3。所述内侧壁7上形成有若干凸起4，所述若干凸起4彼此间隔排布。Referring to FIG. 1 , it is a vertical perspective view of the jacket structure of the present invention. The jacket structure includes an inner wall 7 and an outer wall 8 , and the gap between the inner wall 7 and the outer wall 8 is filled with a sound-insulating material 3 . A plurality of protrusions 4 are formed on the inner side wall 7, and the plurality of protrusions 4 are arranged at intervals with each other.
参见图2-3，分别为本发明外套结构凸起4内的隔音材料未完全充盈状态和完全充盈状态的侧视图，所述外套结构的内侧设置有一内部构件1，所述内部构件1可以为通风管道、风机部位外套管或消音器套管。即第一，本发明外套结构可以套接于通风管道整体的外部；第二，本发明外套结构也可以只套接于风机所在部位的部分通风管道外部，因为风机是通风系统中重要噪音来源，在主要噪音源位置附近布置外套结构，可以节约使用长度和成本；第三，本发明外套结构也可以套接在已有消音器套管的外部，这样不仅可以节约成本也可以实现噪音阻消效果的加强。Referring to Figures 2-3, they are side views of the incompletely filled state and the fully filled state of the sound-insulating material in the casing structure protrusion 4 of the present invention, an internal component 1 is provided on the inside of the casing structure, and the internal component 1 can be Ventilation ducts, casings for fan parts or casings for mufflers. That is, the first, the jacket structure of the present invention can be socketed on the outside of the ventilation duct as a whole; the second, the jacket structure of the present invention can only be socketed outside the part of the ventilation pipe where the fan is located, because the fan is an important source of noise in the ventilation system. Arranging the jacket structure near the main noise source can save the length and cost of use; thirdly, the jacket structure of the present invention can also be sleeved on the outside of the existing muffler sleeve, which can not only save costs but also achieve the effect of noise reduction strengthening.
以通风管道作为内部构件为例，可选的，其内可以具有一风机2，所述风机2通过支撑装置(图中未示出)固定于内部构件1内。所述凸起4向内抵接于所述内部构件1的外侧，由于凸起4彼此间隔排布从而使所述内侧壁7与所述内部构件1的外侧之间形成不连续的空隙5，所述空隙5构成了可阻消中高频噪音的中空结构；所述内侧壁7与外侧壁8之间填充的隔音材料3设置为中低频噪音阻消有机材料，所述中低频噪音阻消有机材料优选为PVB树脂。因此，本发明外套结构可同时兼顾阻消中高频噪音和低频噪音。Taking the ventilation duct as the internal component as an example, optionally, there may be a fan 2 inside it, and the fan 2 is fixed in the internal component 1 through a supporting device (not shown in the figure). The protrusions 4 abut against the outer side of the inner member 1 inwardly, and since the protrusions 4 are spaced apart from each other, a discontinuous gap 5 is formed between the inner side wall 7 and the outer side of the inner member 1 , The gap 5 constitutes a hollow structure that can block middle and high frequency noise; the sound insulation material 3 filled between the inner side wall 7 and the outer side wall 8 is set as an organic material for middle and low frequency noise suppression, and the middle and low frequency noise suppression organic material The material is preferably PVB resin. Therefore, the jacket structure of the present invention can take into account both middle and high-frequency noise and low-frequency noise elimination.
进一步的，所述内侧壁7的材料为柔性、弹性或刚性材料，所述外侧壁8的材料为柔性、弹性或刚性材料，所述凸起4的材料为柔性、弹性或刚性材料。优选地，所述凸起4的材料为柔性或弹性材料。Further, the material of the inner side wall 7 is flexible, elastic or rigid material, the material of the outer side wall 8 is flexible, elastic or rigid material, and the material of the protrusion 4 is flexible, elastic or rigid material. Preferably, the material of the protrusion 4 is flexible or elastic material.
需要进一步说明的是，当所述凸起4的材料为柔性或弹性材料，可通过控制所述凸起4内部隔音材料的充盈与否来进行外套结构的安装实施。当所述凸起4的材料为刚性材料时，可通过控制所述内侧壁7与外侧壁8之间隔音材料的充盈与否来进行外套结构的安装实施。在本发明中，优选所述凸起4的材料为柔性或弹性材料。It should be further explained that when the material of the protrusion 4 is a flexible or elastic material, the installation and implementation of the jacket structure can be carried out by controlling whether the sound insulation material inside the protrusion 4 is filled or not. When the material of the protrusion 4 is a rigid material, the installation and implementation of the jacket structure can be carried out by controlling whether the sound insulation material between the inner side wall 7 and the outer side wall 8 is filled or not. In the present invention, preferably, the material of the protrusion 4 is a flexible or elastic material.
具体地，所述凸起4具有向内侧突出的外表面，以及形成于所述外表面内的内部空间，所述外表面与所述内侧壁7相连，优选地，所述凸起4的外表面与所述内侧壁7一体成型相连；并且，所述内部空间可完全充盈或未完全充盈的填充有所述隔音材料，而所述内部空间中填充的隔音材料与所述内侧壁与外侧壁之间填充的隔音材料3相连通。Specifically, the protrusion 4 has an outer surface protruding inward, and an inner space formed in the outer surface, the outer surface is connected with the inner side wall 7, preferably, the outer surface of the protrusion 4 The surface is integrally connected with the inner side wall 7; and, the inner space can be fully filled or partially filled with the sound insulation material, and the sound insulation material filled in the inner space is compatible with the inner side wall and the outer side wall The sound insulation material 3 filled in between communicates.
参见图2-3，在所述内侧壁或外侧壁上设置有第一通孔，优选地在所述外侧壁上设置第一通孔6，通过所述第一通孔6可向所述内侧壁7与外侧壁8之间进一步注入所述隔音材料3，使所述凸起的所述内部空间由所述未完全充盈填充有所述隔音材料变为所述完全充盈填充有所述隔音材料。Referring to Fig. 2-3, a first through hole is provided on the inner side wall or the outer side wall, preferably a first through hole 6 is set on the outer side wall, through which the first through hole 6 can go to the inner side The sound insulation material 3 is further injected between the wall 7 and the outer wall 8, so that the inner space of the protrusion is filled with the sound insulation material from the incomplete filling to the full filling with the sound insulation material .
此外，在所述内侧壁7或外侧壁8上还可以设置有第二通孔(图中未示出)，在所述内侧壁7与外侧壁8之间还设置有开口与所述第二通孔相连接的气囊(图中未示出)；通过所述第二通孔可向所述气囊注入气体，进而通过所述气囊的膨胀使得所述凸起4的所述内部空间由所述未完全充盈填充有所述隔音材料变为所述完全充盈填充有所述隔音材料。由此可以利用凸起4内隔音材料3完全充盈和未完全充盈的状态变化，实现凸起4向内抵压内侧壁7的支撑力变化。In addition, a second through hole (not shown in the figure) may also be provided on the inner side wall 7 or the outer side wall 8, and an opening and the second through hole may be arranged between the inner side wall 7 and the outer side wall 8. An air bag (not shown) connected to the through hole; gas can be injected into the air bag through the second through hole, and the expansion of the air bag makes the inner space of the protrusion 4 filled by the The incomplete filling with the sound-insulating material becomes the full-filling with the sound-insulating material. In this way, the change of the state of the sound-insulating material 3 in the protrusion 4 being fully filled or not fully filled can be used to realize the change of the support force of the protrusion 4 pressing inwardly against the inner wall 7 .
需要说明的是，本发明可以采用单档调节凸起状态机制，即仅具有第一通孔来调节凸起4内隔音材料3填充的状态。也可以采用具有两档调节凸起状态机制，即至少具有所述第一通孔、第二通孔和气囊，来调节凸起4内隔音材料3填充的状态。It should be noted that the present invention can adopt a single-speed mechanism for adjusting the state of the protrusion, that is, only the first through hole is used to adjust the filling state of the sound-insulating material 3 in the protrusion 4 . It is also possible to use a two-level mechanism for adjusting the protrusion state, that is, at least the first through hole, the second through hole and the air bag to adjust the filling state of the sound insulation material 3 in the protrusion 4 .
此外，本发明还提供一种外套结构的实施方法，所述凸起4的材料为柔性或弹性材料，包括以下步骤：In addition, the present invention also provides a method for implementing the jacket structure, the material of the protrusion 4 is a flexible or elastic material, comprising the following steps:
(1)在所述凸起4未完全充盈填充有所述隔音材料3时，实施所述外套结构在所述内部构件外侧的安装布置：若以嵌套方式安装，由于凸起4未完全充盈隔音材料，凸起4的外表面与内侧壁7留有一定空隙，因此外套结构安装阻力较小、安装难度较低；若以连接件安装，由于凸起4未完全充盈隔音材料，其连接件连接时的阻力较小，容易卡合。(1) When the protrusion 4 is not fully filled with the sound-insulating material 3, implement the installation arrangement of the outer shell structure on the outside of the internal member: if it is installed in a nested manner, since the protrusion 4 is not fully filled Sound insulation material, there is a certain gap between the outer surface of the protrusion 4 and the inner side wall 7, so the installation resistance of the jacket structure is small and the installation difficulty is low; There is less resistance when connecting, and it is easy to snap.
(2)在所述安装布置后，通过第一通孔6注入隔音材料3或/和通过第二通孔向气囊注入气体，使所述凸起4的内部空间由所述未完全充盈填充有所述隔音材料变为所述完全充盈填充有所述隔音材料。此时凸起4完全凸起，与内侧壁7构成更大的空隙，再通过中低频噪音阻消有机材料，即可实现同时兼顾阻消中高频噪音和低频噪音；同时凸起4的完全凸起也对内部构件1起到了良好的支撑缓震作用。(2) After the installation and arrangement, inject the sound insulation material 3 through the first through hole 6 or/and inject gas into the airbag through the second through hole, so that the inner space of the protrusion 4 is filled with the incomplete filling The sound deadening material becomes the full filling filled with the sound deadening material. At this time, the protrusion 4 is completely raised, forming a larger gap with the inner side wall 7, and then through the middle and low frequency noise blocking organic material, it can realize the simultaneous elimination of middle and high frequency noise and low frequency noise; It also plays a good supporting and cushioning effect on the internal component 1.
此外，虽然已经显示并描述了本发明总体构思的若干实施例和优选实施方式，但是本领域的技术人员应该理解，在不脱离本发明总体构思的原理和精神的情况下，可以对这些实施例进行改变，本发明的总体构思由权利要求及其等同物限定。In addition, although several embodiments and preferred implementations of the present general inventive concept have been shown and described, those skilled in the art should understand that these embodiments can be modified without departing from the principle and spirit of the present general inventive concept.
