Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower construction technology, specifically a wind turbine tower cable clamp assembly. Background Technology

[0002] The wind turbine tower is a crucial component of a wind turbine generator set, primarily serving to support and protect the generator. Located at the base of the turbine, it supports the nacelle and blades, ensuring the stable operation of the entire unit. The tower's design mitigates vibrations and impacts experienced by the wind turbine during operation, extending the unit's lifespan.

[0003] Cable clamps are devices used in electrical installations to secure and support cables. Their main functions are to prevent excessive cable movement or damage, maintain spacing between cables, and restrict cable movement during short circuits or faults, thereby ensuring the integrity of the electrical system. Cable clamps are typically made of stainless steel, polymer compounds, or other metal alloys and come in various shapes and sizes, and can be customized to fit different cable diameters and configurations.

[0004] Conventional cable clamp assemblies have relatively fixed structures, making it difficult to adapt the structure to the number of cables being processed. In addition, since common materials are usually made of stainless steel or other metal alloys, their own weight can cause the cables to sag due to structural issues. Furthermore, the lifespan of metal materials varies in different environments, resulting in relatively limited effectiveness. Utility Model Content

[0005] The purpose of this utility model is to provide a wind turbine tower cable clamp assembly to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine tower cable clamp assembly, comprising a clamping sleeve and a first clamping member. The first clamping member is provided on one side of the outer side of the clamping sleeve, and a second clamping member is provided on the other side of the clamping sleeve. A fastening bolt is horizontally installed at the connection between the first clamping member and the second clamping member. A combination frame is installed on the surface of the first clamping member and the second clamping member away from the clamping sleeve. The first clamping member comprises a first housing, a first connecting seat, a first connecting block, a first limiting ring, and a docking hole. The first connecting seat is provided in the middle of the surface of the first housing away from the clamping sleeve, and the first connecting block is provided on the upper and lower surfaces of the first housing. The first limiting ring is provided at both ends of the first housing, and the docking hole is horizontally opened on the side of the first limiting ring near the second clamping member.

[0007] Furthermore, the clamping sleeve includes a support sleeve, a protective pad, and a stabilizing groove. The protective pad is installed on the inner wall surface of the support sleeve, and the stabilizing groove is provided on the outer surface of the support sleeve.

[0008] Furthermore, the protective pad is fixedly installed on the inner wall surface of the support sleeve, and the stabilizing grooves are symmetrically arranged at the front and rear ends of the support sleeve.

[0009] Furthermore, a set of clamping sleeves is provided on each of the left and right sides symmetrically. The first clamping member includes a first housing, a first connection seat, a first connection block, and a first limiting ring, which are integrally structured and made of carbon fiber composite materials.

[0010] Furthermore, the fastening bolt and the first connection block are in threaded connection. The combined frame is arranged in a "U" shape structure. The surface structure of the end of the combined frame close to the first connection seat matches the surface structure of the first connection seat. And hole structures for installing bolts are provided at the four diagonal corners of the connection between the first connection seat and the combined frame.

[0011] Furthermore, the second clamping member includes a second housing, a second connection seat, a second connection block, a second limiting ring, and a docking plug. A second connection seat is provided in the middle of the surface of the second housing away from the clamping sleeve. Second connection blocks are provided on the upper and lower surfaces of the second housing. Second limiting rings are provided at the front and rear ends of the second housing. And docking plugs are horizontally arranged at both ends of the second limiting ring close to the first clamping member.

[0012] Furthermore, the structure between the second connection seat and the first connection seat is the same. The second connection block and the first connection block are对接组合 by an insertion structure, and the fastening bolt and the second connection block are in threaded connection.

[0013] Furthermore, the structure between the second limiting ring and the first limiting ring is the same. The inner surface structure of the docking hole matches the outer surface structure of the docking plug. The second clamping member and the first clamping member are made of the same material.

[0014] The present utility model provides a cable clamp assembly for a wind turbine tower barrel, having the following beneficial effects:

[0015] It should be noted that there is a misspelling in the original text. "对接组合" should be "对接组合" which is translated as "docked and combined". And "几”字形结构" should be "U” shape structure" which is translated as "U" shape structure". Also, the text contains some special tags etc. which are kept unchanged as required.1. This utility model utilizes two sets of first and second clamping components made of carbon fiber composite material. Carbon fiber composite material is a high-performance material formed by combining carbon fiber reinforcing material with matrix materials such as resin, metal, and ceramics through physical or chemical methods. It possesses excellent properties such as lightweight, high strength, and high modulus. This allows the first and second clamping components to provide a certain degree of structural protection for the clamping sleeve while also possessing good structural strength, strong wear resistance, and corrosion resistance to adapt to complex environments. This facilitates the use of the entire structure in different scenarios, improving its overall applicability. Furthermore, due to its lightweight characteristics, the entire structure will not exert excessive downward force on the cable after clamping it, reducing unnecessary structural impact on the cable. In use, simply insert the docking post on one side of the second limiting ring and the docking hole on one side of the first limiting ring, then insert and dock the first connecting block and the second connecting block, and use fastening bolts to achieve a firm splicing combination between the first and second clamping components.

[0016] 2. This utility model, by structurally connecting a support sleeve with a stabilizing groove on its surface to the first and second limiting rings respectively, allows the clamping sleeve to be quickly embedded into the interior of the first and second clamping components. This structure achieves both convenience in structural assembly and ensures the structural stability after assembly, preventing slippage and separation. The protective pad ensures tight and secure contact with the cable surface without causing structural damage, thus providing structural protection. Furthermore, by connecting and fixing the two sets of assembly frames to the sides of the first and second clamping components respectively, the entire component structure can be expanded, allowing multiple component structures to be sequentially spliced ​​together. This facilitates flexible structural adjustments based on different numbers of cables and allows for adjustments in relatively narrow spaces. Additionally, the assembly frame itself can connect components while providing good structural support and mutual buffering between multiple components, ensuring the applicability of the component structure.

The first clamping member 2 includes a first housing 201, a first connecting seat 202, a first connecting block 203, a first limiting ring 204, and a mating hole 205. The first connecting seat 202 is provided in the middle of the surface of the first housing 201 away from the clamping sleeve 1, and the first connecting block 203 is provided on the upper and lower surfaces of the first housing 201. The first housing 201 has a first limiting ring 204 at both ends. The first limiting ring 204 has a horizontally opening docking hole 205 on the side of the first limiting ring 204 near the second clamping member 3. The clamping sleeve 1 has a set of one set on each side. The first clamping member 2 includes the first housing 201, the first connecting seat 202, the first connecting block 203 and the first limiting ring 204. They are all made of carbon fiber composite material. In use, it is only necessary to insert the docking pin 305 on the side of the second limiting ring 304 and the docking hole 205 on the side of the first limiting ring 204, and then insert the first connecting block 203 and the second connecting block 303 to dock. With the use of the fastening bolt 4, a firm splicing combination between the first clamping member 2 and the second clamping member 3 is achieved.

[0025] like Figures 1 to 5 As shown, the fastening bolt 4 and the first connecting block 203 are in threaded connection. The combined frame 5 is arranged in a "Ji" - shaped structure, and the surface structure of one end of the combined frame 5 close to the first connecting seat 202 matches the surface structure of the first connecting seat 202. Moreover, hole structures for installing bolts are provided at the four diagonal corners of the connection between the first connecting seat 202 and the combined frame 5. The clamping sleeve 1 includes a support sleeve 101, a protective pad 102 and a stabilizing groove 103. A protective pad 102 is installed on the inner wall surface of the support sleeve 101, and a stabilizing groove 103 is provided on the outer surface of the support sleeve 101. The protective pad 102 is fixedly installed on the inner wall surface of the support sleeve 101, and the stabilizing grooves 103 are symmetrically arranged at the front and rear ends of the support sleeve 101. The second clamping member 3 includes a second housing 301, a second connecting seat 302, a second connecting block 303, a second limiting ring 304 and a docking plug 305. A second connecting seat 302 is provided in the middle of the surface of the second housing 301 far from the clamping sleeve 1, and second connecting blocks 303 are provided on the upper and lower surfaces of the second housing 301. Moreover, second limiting rings 304 are provided at the front and rear ends of the second housing 301, and docking plugs 305 are horizontally arranged on both ends of the second limiting ring 304 close to the first clamping member 2.

The inner surface structure of the docking hole 205 matches the outer surface structure of the docking plug 305. The second clamping member 3 and the first clamping member 2 are made of the same material. By structurally docking the support sleeve 101 with a stabilizing groove 103 on its surface to the first limiting ring 204 and the second limiting ring 304 respectively, the clamping sleeve 1 can be quickly embedded into the interiors of the first clamping member 2 and the second clamping member 3.

[0026] In summary, as Figures 1 to 5 shown, when the wind turbine tower cable clamp assembly is in use, first, the two clamping sleeves 1 are used. The support sleeve 101 with a protective pad 102 on its inner wall is docked and inserted with the first limiting ring 204 and the second limiting ring 304 through the stabilizing grooves 103 at both ends, so that the clamping sleeve 1 is quickly embedded into the interiors of the first clamping member 2 and the second clamping member 3. Then, the side of the support sleeve 101 with the protective pad 102 is fitted to the surface of the cable, and the first clamping member 2 and the second clamping member 3 connected to the clamping sleeve 1 are spliced left and right;

[0027] In this process, the first clamping component 2 and the second clamping component 3 are quickly spliced ​​by inserting the docking pin 305 horizontally into the docking hole 205, and the first connecting block 203 and the second connecting block 303 are structurally installed. The clamping sleeve 1 is used to clamp the cable. Then, the fastening bolt 4 is used to connect and fix the spliced ​​second connecting block 303 and the first connecting block 203.

[0028] However, when multiple component structures need to be combined and connected one by one, it is only necessary to connect the combination frame 5 to the first connecting seat 202 and the second connecting seat 302 on both sides of each component, and fix it at the four diagonal corners of the four sets of bolts. Then, connect the combination frames 5 on the sides of the two adjacent components and fix them with bolts.
