[0038] Furthermore, in the description of the examples, detailed descriptions of well-known related components or functions will be omitted when it is believed that such detailed descriptions would lead to a vague interpretation of the present invention.

[0039] The following will combine Figures 1 to 6 The present invention will now be described in the form of a clamping component provided in an embodiment of the present invention.

[0040] According to a first aspect embodiment of the present invention, a clamping component is provided, wherein, as Figures 1 to 6 As shown, the clamping components include a first clamping plate 10, a second clamping plate 20, and a connecting assembly 30. The first clamping plate 10 is used to fix it to a target component of the wind turbine generator set (such as the inner wall of the tower). The second clamping plate 20 is opposite to and independently arranged with respect to the first clamping plate 10. The connecting assembly 30 passes through the second clamping plate 20 and connects to the first clamping plate 10. By adjusting the connection position of the connecting assembly 30 on the first clamping plate 10, the distance between the second clamping plate 20 and the first clamping plate 10 can be adjusted, thereby forming receiving cavities 40 of different sizes between the first clamping plate 10 and the second clamping plate 20 to accommodate and fix components of different sizes in the wind turbine generator set to be clamped. As an example, the components to be clamped may include cables, pipes, etc.

[0041] According to the clamping component provided in this embodiment of the present invention, the distance between the second clamping plate 20 and the first clamping plate 10 can be changed by adjusting the connection position between the connecting component 30 and the first clamping plate 10, thereby forming an adjustable-size receiving cavity 40. In this way, during use, the size of the receiving cavity 40 can be adjusted to adapt to the size requirements of the component to be clamped, so that the clamping component can tightly clamp and support components of different sizes, thereby enabling the clamping component to meet the needs of wind turbine development.

[0042] In this embodiment, the receiving cavity 40 can accommodate the component to be clamped and can clamp and fix the component. In this invention, the clamping component can clamp cables of various sizes; for example, it can clamp cables with a diameter of 30mm-40mm.

[0043] To improve the cable fixing effect, limiting grooves can be provided on the first clamping plate 10 and the second clamping plate 20 opposite to the receiving cavity 40 to restrict cable movement. Furthermore, anti-slip protrusions can be provided on the surface of the limiting grooves, thereby ensuring the reliability of the clamping component provided according to the present invention in fixing the cable during use, and preventing the cable from falling after installation.

[0044] The following will provide a detailed description with reference to specific embodiments.

[0045] According to some embodiments of this application, the first clamping plate 10 and the second clamping plate 20 are respectively provided with at least one first groove and at least one second groove on their end faces opposite to the receiving cavity 40, with each first groove and each second groove facing each other. It should be noted that when there are multiple first grooves, adjacent first grooves may or may not be directly connected. In practical use, one end of the cable is confined within the first groove and one of the second grooves opposite to the first groove. This allows for greater frictional force to hold the cable securely, ensuring a firm fixation. The same applies to the second grooves, which will not be discussed further here.

[0046] According to some other embodiments of this application, one of the first clamping plate 10 and the second clamping plate 20 is provided with N first limiting grooves 11 on the end face facing the receiving cavity 40, and the other of the first clamping plate 10 and the second clamping plate 20 is provided with N-1 second limiting grooves 21 on the end face facing the receiving cavity 40. The first limiting grooves 11 and the second limiting grooves 21 are staggered, wherein N is an even number greater than or equal to 2.

[0047] In these embodiments, the first clamping plate 10 and the second clamping plate 20 are provided with a first limiting groove 11 and a second limiting groove 21 that are staggered on their end faces opposite to the receiving cavity 40. This means that the first limiting groove 11 and the second limiting groove 21 are not directly aligned, but are offset or misaligned. In this way, when multiple cables are clamped in the receiving cavity, the multiple cables can be stably fixed in the clamping components by means of the squeezing force between them and under the dual restraint of the first limiting groove and the second limiting groove, which can prevent the cables from falling after installation.

[0048] In some embodiments, the first limiting groove 11 and the second limiting groove 21 are arc-shaped grooves. The arc-shaped grooves can better fit the shape of conventional arc-shaped cables, reducing the friction and wear of the cables in the grooves. As a result, the cables are less likely to be scratched during use, thereby extending the service life of the cables.

[0049] In some embodiments, the second limiting groove 21 faces and communicates with the adjacent first limiting groove 11. Specifically, a second limiting groove 21 communicates with the adjacent first limiting groove 11 and forms a generally heart-shaped receiving cavity 40. This heart-shaped receiving cavity 40 can be used to accommodate three-phase cables and provide them with stable support and positioning, while ensuring that the relative positions between the cables do not change arbitrarily, thus ensuring long-term reliability.

[0050] According to this application, the inner wall surfaces of the first limiting groove 11 and the second limiting groove 21 are provided with anti-slip ribs, which can increase the friction between the inner wall surface of the limiting groove and the cable contained therein, thereby ensuring that the cable can be more securely fixed in the limiting groove, so that it can remain in its original position even when subjected to external force or vibration, and can prevent the cable from falling after installation.

[0051] In some embodiments, there are multiple anti-slip ribs. Multiple strip-shaped anti-slip ribs can increase the friction between the inner wall surface of the limiting groove and the cable being accommodated, so as to ensure that the cable can be more securely fixed in the receiving cavity 40 between the first clamping plate 10 and the second clamping plate 20.

[0052] Specifically, there are multiple anti-slip ribs, which can extend from one end to the other in the form of strips along the inner wall of the first limiting groove 11 and the second limiting groove 21. In this way, multiple anti-slip ribs can fully cover the inner wall of the limiting groove, thereby providing a more uniform and stable friction force.

[0053] According to this application, after installation, it can withstand a weight of 100KG for more than 72 hours without falling off, indicating that the clamping components have good fastening and can bear the weight and hold the cable, thus preventing the cable from falling after installation.

[0054] According to this application, the clamping component includes a connecting assembly 30, which can pass through the second clamping plate 20 and connect to the first clamping plate 10 to form an adjustable clamping component.

[0055] As an example, the connecting assembly 30 may include a bolt and nut assembly, a slide rail, or other adjustable connecting components, thereby enabling the distance between the second clamping plate 20 and the first clamping plate 10 to be adjusted as needed. This variety of connecting assemblies 30 can adapt to different installation requirements and scenarios.

[0056] According to some exemplary embodiments of this application, the lower end of the second clamping plate 20 has a slot 22 with an opening at the lower end, and the connecting component 30 is an adjusting bolt 31. The adjusting bolt 31 is threadedly connected to the first clamping plate 10. The second clamping plate 20 can be inserted into the adjusting bolt 31 through the slot 22, and is supported on the adjusting bolt 31, and is located between the bolt head of the adjusting bolt 31 and the first clamping plate 10.

[0057] like Figures 1 to 4 As shown, the lower end of the second clamping plate 20 has a slot 22 with an opening at the lower end. The connecting component 30 is an adjusting bolt 31. The adjusting bolt 31 is connected to the first clamping plate 10. The second clamping plate 20 can be inserted into the adjusting bolt 31 through the slot 22 and is supported on the adjusting bolt 31, and is located between the bolt head of the adjusting bolt 31 and the first clamping plate 10.

[0058] During installation, the first clamping plate 10 can be fixed first, and then the two sets of connecting components 30 can be initially fixed on the first clamping plate 10. Then, the cable is arranged between the two sets of connecting components 30. Then, the second clamping plate 20 is inserted into the corresponding position on the adjusting bolt 31 between the bolt head of the adjusting bolt 31 and the first clamping plate 10 through the slot 22 on it. Finally, the distance between the two clamping plates is adjusted by rotating the bolt until the required clamping force and stability are achieved.

[0059] In these embodiments, the adjusting bolt 31 only needs to be threadedly connected to the first clamping plate 10, and the second clamping plate 20 can be inserted into the adjusting bolt 31 through the slot 22 and supported on the adjusting bolt 31, and is located between the bolt head of the adjusting bolt 31 and the first clamping plate 10. The connection method is simple, thus enabling rapid assembly and improving installation efficiency.

[0060] In some embodiments, the second clamping plate 20 is provided with a gasket limiting groove 23, which is located on one side of the slot 22 and communicates with the slot 22. A gasket 32 ​​is sleeved on the adjusting bolt 31. When the second clamping plate 20 is inserted into the adjusting bolt 31, the gasket 32 ​​can be locked in the gasket limiting groove 23 to restrict the movement of the second clamping plate 20.

[0061] Specifically, the gasket limiting groove 23 is a circular groove, and the diameter of the circular groove is larger than the lower opening of the slot 22.

[0062] In these embodiments, a gasket limiting groove 23 is formed on the second clamping plate 20, located on one side of the slot 22, and communicates with the slot 22. A gasket 32 ​​is fitted onto the adjusting bolt 31. When the second clamping plate 20 is inserted into the adjusting bolt 31, the gasket 32 ​​is laterally pressed into the gasket limiting groove 23 during the tightening of the adjusting bolt 31. Thus, after installation, the gasket is locked in the gasket limiting groove 23 to hook the second clamping plate 20, preventing it from falling off during use. Furthermore, by providing a gasket, when the adjusting bolt 31 is tightened, the gasket can fill any unevenness at the connection point, making the connection tighter and ensuring a stable and reliable connection. In addition, in applications requiring vibration or impact loads, the gasket can act as a buffer, reducing loosening caused by vibration or external forces.

[0063] According to some exemplary embodiments of this application, the connecting component 30 is a connecting bolt, the second clamping plate 20 is provided with a connecting through hole, and the first clamping plate 10 is provided with a threaded hole. In the actual assembly process, the connecting bolt passes through the connecting through hole and the threaded hole in sequence and is threadedly connected to the first clamping plate 10.

[0064] exist Figure 5 and Figure 6 The diagram shows the case where the connecting component 30 is a connecting bolt.

[0065] In these embodiments, the operator simply passes the connecting bolt sequentially through the connecting through hole on the second clamping plate 20 and the threaded hole on the first clamping plate 10, and tightens the bolt until it is fully screwed into the threaded hole and achieves the required tightness. This connection method is robust and ensures that the clamping components will not fail due to loosening when holding an object.

[0066] In some embodiments, the connecting bolt is a captive screw, including a bolt head, a smooth rod section connected to the bolt head, and a threaded section connected to the smooth rod section. The smooth rod section is disposed in the second clamping plate 20, and the threaded section is threadedly connected to the first clamping plate 10.

[0067] In these embodiments, a connecting bolt is used to pass through the first clamping plate 10 and be threadedly connected to the second clamping plate 20. Since the connecting bolt passing through the second clamping plate 20 will not generate too much friction with the second clamping plate 20, and the connecting bolt only needs to be threadedly connected to the first clamping plate 10, thus enabling rapid assembly and improving installation efficiency.

[0068] In some embodiments, the connecting components 30 are in two sets, threadedly connected to opposite sides of the first clamping plate 10.

[0069] In these embodiments, two sets of connecting components 30 are threadedly connected to opposite sides of the first clamping plate 10, which can distribute the clamping force when clamping the cable, reduce the pressure on a single connection point, and thus improve the durability and stability of the clamp. At the same time, since the two sets of connecting components 30 are located on opposite sides of the first clamping plate 10, they can provide mutual support and prevent the clamp from twisting or deforming during the clamping process.

[0070] In some embodiments, a connecting rod 13 is provided on the end face of the first clamping plate 10 opposite to the second clamping plate 20, and the first clamping plate 10 is connected to the target component through the connecting rod 13. During installation, the connecting rod 13 can be connected to the target component to achieve a fixed connection between the first clamping plate 10 and the target component.

[0071] In some embodiments, the first clamping plate 10 and the second clamping plate 20 are made of metal or PC, respectively. The variety of materials available can meet different installation needs and scenarios.

[0072] According to a second aspect of the present invention, a tower is provided, wherein the tower includes a tower body, a cable arranged downward from the tower body, and a clamping member as described above, wherein the inner wall of the tower body serves as a target component, the first clamping plate 10 of the clamping member can be fixed on the inner wall of the tower body, and the cable can be installed in the receiving cavity 40 of the clamping member.

[0073] In this embodiment of the application, the connection position between the connecting component 30 and the first clamping plate 10 can be adjusted so that the second clamping plate 20 presses the cable against the first clamping plate 10 to fix the cable.

[0074] According to a third aspect of the present invention, a wind turbine generator set is provided, wherein the wind turbine generator set includes a tower as described above and a nacelle disposed at the upper end of the tower.

[0075] While the embodiments of the present invention have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope thereof. However, it should be understood that, in the view of those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
