Description

Technical Field

[0001] This utility model relates to the technical field of cable reinforcement, and in particular to a protective reinforcement device for wind turbine power cables. Background Technology

[0002] In modern wind power generation systems, power cables are key components connecting various parts of the wind turbine and transmitting electrical energy. Their operational stability directly affects the power generation efficiency and reliability of the wind farm. Because wind turbines are exposed to complex environments such as high altitudes, strong winds, and vibrations for extended periods, the cables not only need to withstand the effects of natural environmental factors but also need to cope with mechanical vibrations, swaying, and stress concentrations caused by changes in wind load during turbine operation.

[0003] Traditional cable protection methods often employ simple fixing clamps or sleeves, but these devices have many drawbacks during long-term operation. The fixed-angle clamping structure of conventional clamps cannot match the swing amplitude of wind turbines under different operating conditions, leading to frequent cable bending and subsequent internal conductor breakage. Furthermore, existing protection devices typically lack height adjustment functions, making it difficult to meet the needs of cable maintenance and repair, as well as the installation requirements of wind turbines at different heights.

[0046] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0047] See Figure 1-5 As shown;

[0048] A wind turbine power cable protection and reinforcement device according to an embodiment of this utility model includes:

[0049] Lifting mechanism 1 is installed on the wind turbine unit;

[0050] Adjustment mechanism 2 is mounted on lifting mechanism 1;

[0051] The clamping mechanism 3 is mounted on the adjusting mechanism 2 and is used to clamp the cable. The angle is adjusted by the adjusting mechanism 2.

[0052] The regulating mechanism 2 includes:

[0053] An adjusting support 21 is provided on the lifting mechanism 1, and a hinge seat 22 is provided on the adjusting support 21.

[0054] The swing seat plate 23 is swing-mounted on the hinge seat 22;

[0055] A drive assembly, mounted on the adjusting support 21, is used to drive the swing plate 23 to swing.

[0056] Clamping mechanism 3 includes:

[0057] The clamping branch pipe 31 is fixedly installed on the swing seat plate 23;

[0058] The adjusting support 32 is inserted into the clamping support tube 31;

[0059] The clamping arm 33 is fixedly installed on the adjusting support column 32;

[0060] The movable clamping arm 34 is oscillatingly mounted on the fixed clamping arm 33;

[0061] The screw-hole shaft 35 is rotatably mounted on the fixed clamping arm 33;

[0062] The adjusting bolt 36 is threaded into the screw hole shaft 35, and the end of the adjusting bolt 36 is hinged to the main body of the movable clamping arm 34.

[0063] Tighten the adjusting bolt 36. The adjusting bolt 36 is threaded with the screw hole shaft 35. Tightening it clockwise will push the movable clamping arm 34 to swing towards the fixed clamping arm 33, thereby clamping the cable.

[0064] By adopting the above technical solution, when it is necessary to install or maintain cables at different heights, or to adapt to different installation requirements of wind turbine units, the lifting mechanism 1 is activated; the lifting mechanism 1 drives the adjusting mechanism 2 to rise or fall along the vertical direction of the wind turbine unit, moving the entire protective reinforcement device to a suitable height, providing a foundation for subsequent operations; during the operation of the wind turbine unit, the cable swing amplitude changes due to factors such as wind load changes, at which point the drive component starts to work; the drive component acts on the swing seat plate 23, causing it to swing around the hinge seat 22, driving the cable set in the swing seat plate 23 to swing around the hinge seat 22 to swing the cable set in the hinge seat 22 to the hinge seat 23 to the swing seat plate ... The clamping mechanism 3 on the swing base plate 23 adjusts its angle to match the swing amplitude of the cable under different operating conditions of the wind turbine, thus preventing excessive bending of the cable. The cable is placed between the fixed clamping arm 33 and the movable clamping arm 34. By tightening the adjusting bolt 36, which is threaded into the screw hole shaft 35, clockwise tightening of the adjusting bolt 36 pushes the movable clamping arm 34 towards the fixed clamping arm 33, gradually clamping the cable. The adjusting mechanism 2 of this device drives the swing base plate 23 to swing via the drive assembly, thus enabling the clamping mechanism 3 to... The device allows for flexible angle adjustment, preventing frequent cable bending, effectively preventing internal conductor breakage, and extending cable lifespan. Existing protective devices lack lifting and adjustment functions, making it difficult to meet the needs of cable maintenance and repair as well as installation at different heights. The lifting mechanism 1 enables the vertical lifting of the adjustment mechanism 2 and the clamping mechanism 3, facilitating convenient operation whether repairing cables at high positions on the wind turbine or installing cables at different heights. This improves installation and maintenance efficiency and reduces operational difficulty and safety risks for workers. The insertion and extraction of the adjustment support column 32 and the clamping branch pipe 31 in the clamping mechanism 3, as well as the linkage structure between the adjustment bolt 36 and the movable clamping arm 34, can adaptively clamp cables of different diameters and specifications. This eliminates the need for multiple special clamps for different cables, improving the device's versatility and applicability. The device effectively mitigates the effects of mechanical stress and environmental corrosion on cables in complex environments, ensuring stable connection and power transmission during wind turbine operation, improving the overall reliability and power generation efficiency of the wind turbine, and reducing downtime and maintenance costs caused by cable faults.

[0065] As a preferred embodiment of the above technical solution, such as Figure 3As shown, the adjusting support 32 is slidably inserted into the clamping support tube 31, and a locking screw 37 is threadedly inserted into the clamping support tube 31. The locking screw 37 is used to fasten the adjusting support 32.

[0066] In this embodiment, when it is necessary to adjust the position of the clamping mechanism 3 in the height direction to adapt to different installation requirements or cable layout, the operator can loosen the locking screw 37 on the clamping support tube 31. Since the adjusting support 32 is slidably inserted into the clamping support tube 31, after the locking screw 37 is loosened, the adjusting support 32 can slide freely within the clamping support tube 31. At this time, the operator can move the adjusting support 32 up or down according to actual needs, thereby driving the fixed clamping arm 33, the movable clamping arm 34, and other clamping components to move together, thereby adjusting the height of the clamping mechanism 3. After the adjusting support 32 moves to the appropriate position, the operator tightens the locking screw 37. During the tightening process, the locking screw 37 will gradually apply pressure to the adjusting support 32, causing the adjusting support to... The increased friction between the adjusting support column 32 and the clamping branch pipe 31 ultimately secures the adjusting support column 32 to its current position within the clamping branch pipe 31, ensuring that the clamping mechanism 3 will not shift due to external forces during operation and guaranteeing the stability of cable clamping. The installation environment of the wind turbine and the cable layout may vary depending on the wind farm and the model of the wind turbine. By adjusting the sliding adjustment function of the support column 32 within the clamping branch pipe 31 and the tightening effect of the locking screw 37, the height of the clamping mechanism 3 can be adjusted according to actual needs. This protective reinforcement device can adapt to wind turbines and cable layouts of different heights and installation positions, improving the versatility and adaptability of the device and reducing the cost of customizing different specifications of the device due to differences in the installation environment.

[0067] As a preferred embodiment of the above technical solution, such as Figure 2 As shown, the driving component includes:

[0068] Motor 24 is fixedly mounted on adjusting support 21;

[0069] The transmission disc 25 is rotatably mounted on the motor 24 and is driven to rotate by the motor 24.

[0070] The drive rod 26 is fixedly mounted on the transmission disc 25 and drives the swing through the transmission disc 25.

[0071] Linkage rod 27 is hinged to drive rod 26;

[0072] Driven hinge rod 28 is mounted on swing seat plate 23 and is hinged to linkage rod 27;

[0073] In this embodiment, when the operating conditions of the wind turbine change and the cable angle needs to be adjusted to accommodate the swing amplitude, the motor 24 starts. The motor 24 is fixedly mounted on the adjusting support 21, and its output shaft begins to rotate. The transmission disk 25 is rotatably mounted on the motor 24. As the output shaft of the motor 24 rotates, the transmission disk 25 also begins to rotate synchronously under the drive of the motor 24. The drive rod 26 is fixedly mounted on the transmission disk 25. When the transmission disk 25 rotates, the drive rod 26 will swing accordingly. The linkage rod 27 is hinged to the drive rod 26. As the drive rod 26 swings, the linkage rod 27 will also move accordingly. At the same time, the driven hinge rod 28 is mounted on the swing seat plate 23 and is hinged to the linkage rod 27. The movement of the linkage rod 27 will drive the driven hinge rod 28. The movement causes the swing plate 23 to swing around the hinge seat 22 on the adjusting support 21. Since the clamping mechanism 3 is fixedly installed on the swing plate 23, the swing of the swing plate 23 will drive the clamping mechanism 3 and the clamped cable to swing together, thereby realizing the adjustment of the cable angle so that it can match the swing amplitude under different operating conditions of the wind turbine. Through the linkage of the motor 24 driving the transmission disk 25, the drive rod 26, the linkage rod 27 and the driven hinge rod 28, the automatic swing of the swing plate 23 is realized, thereby realizing the automatic adjustment of the cable angle. This drive assembly can adjust the cable angle in a timely and accurate manner according to the actual operating conditions of the wind turbine, avoiding the problem of internal conductor breakage caused by frequent bending of the cable, and improving the service life and operational stability of the cable.

[0074] As a preferred embodiment of the above technical solution, such as Figure 4 As shown, a lower limit block 2a is provided at the bottom end of the swing seat plate 23. The lower limit block 2a is used to limit the downward swing stroke of the swing seat plate 23.

[0075] In this embodiment, the power cable of the wind turbine needs to be kept in a reasonable position and angle during operation to avoid excessive bending, stretching or collision with other components. The lower limit block 2a restricts the downward swing stroke of the swing seat plate 23, preventing the cable from being subjected to excessive tension or bending force due to excessive downward swing of the swing seat plate 23, thereby protecting the conductor and insulation layer inside the cable and extending the service life of the cable. At the same time, it also avoids unnecessary collisions between the cable and other components, protecting other related components of the wind turbine.

[0076] As a preferred embodiment of the above technical solution, such as Figure 4 As shown, an upper limit block 2b is provided at the bottom of the swing seat plate 23. The upper limit block 2b is used to limit the upward swing stroke of the swing seat plate 23.

[0077] In this embodiment, if the swing plate 23 swings upward too much during the operation of the wind turbine power cable, it will cause the cable to bend or stretch excessively, resulting in damage to the internal conductor or breakage of the insulation layer, affecting the transmission performance and service life of the cable. The upper limit block 2b limits the upward swing stroke of the swing plate 23, preventing the cable from being damaged due to excessive bending or stretching, and also preventing the cable from colliding with other components, thus improving the stability of use.

[0078] As a preferred embodiment of the above technical solution, noise-reducing rubber pads are provided at the bottom ends of both the lower limit block 2a and the upper limit block 2b.

[0079] In this embodiment, during the operation of the wind turbine, the collision between the swing plate 23 and the limit block will generate significant noise. The noise-reducing rubber pad can effectively absorb and buffer the collision energy, transforming the original rigid collision into elastic contact, greatly reducing the noise generated during the collision, reducing noise pollution to the surrounding environment, and creating a relatively quiet environment for residents and workers around the wind farm. Rigid collisions can easily cause wear, deformation, or even damage to the surfaces of components such as the swing plate 23, the upper limit block 2b, and the lower limit block 2a, affecting the service life and stability of the device. The buffering effect of the noise-reducing rubber pad can reduce the impact force during the collision, reduce the risk of wear and damage between components, extend the service life of the device, and reduce maintenance and replacement costs.

[0080] As a preferred embodiment of the above technical solution, such as Figure 5 As shown, the lifting mechanism 1 includes:

[0081] Lifting support 11 is installed on the wind turbine unit;

[0082] Two guide rods 12 are symmetrically arranged on the lifting support 11;

[0083] The lifting seat 13 is slidably sleeved on the two guide rods 12, and the lifting seat 13 is fixedly connected to the adjusting support 21.

[0084] The lifting screw 14 is rotatably mounted on the lifting support 11, and the lifting screw 14 is threaded into the lifting seat 13. The lifting screw 14 is manually controlled to rotate by a drive handle.

[0085] In this embodiment, when the device needs to be adjusted in height, the operator manually rotates the drive handle, which drives the lifting screw 14 to rotate on the lifting support 11. Since the lifting seat 13 is slidably sleeved on the guide rod 12, the guide rod 12 guides the lifting seat 13, restricting it to linear movement only along the axial direction of the guide rod 12. Simultaneously, the lifting screw 14 is threadedly engaged with the lifting seat 13. When the lifting screw 14 rotates, according to the principle of threaded transmission, the lifting seat 13 will rise or fall along the axial direction of the lifting screw 14. Because the lifting seat 13 is fixedly connected to the adjusting support 21, the rising or falling of the lifting seat 13 will drive the adjusting mechanism 2 and the adjustment support 21. The clamping mechanism 3 on the section mechanism 2 rises or falls together, thereby realizing the lifting and adjustment function of the entire device. The structure and installation environment of wind turbine units are complex and diverse, and different locations may require cable protection and reinforcement devices of different heights. The lifting mechanism 1 allows the device to be adjusted in height according to actual installation needs, ensuring that the device can be accurately installed in the appropriate position, improving the versatility and adaptability of the device. During cable maintenance and repair, it is sometimes necessary to lower the device to a height that is easy to operate, so that workers can inspect, repair or replace the cable. Through the lifting mechanism 1, the device can be easily lowered to a suitable height, providing convenience for maintenance and repair work, improving work efficiency and safety.

[0086] As a preferred embodiment of the above technical solution, such as Figure 5 As shown, the lifting screw 14 and the lifting seat 13 are parallel to each other;

[0087] In this embodiment, the lifting screw 14 and the lifting seat 13 are parallel to each other, ensuring that when the lifting screw 14 rotates, the lifting seat 13 can make precise linear movements along the axis of the lifting screw 14, avoiding motion deviation caused by the two not being parallel, making the lifting process of the device more stable and reliable, and improving the operating accuracy of the device.

[0088] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
