[0052] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0053] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0054] A wind turbine is a power device that converts wind energy into electrical energy and outputs alternating current. When a wind turbine unit is operating, a cable is required to transmit power. Since the cable in the wind turbine tower will hang down more than ten meters, when the external wind blows and the wind force is too strong, the part of the cable hanging inside the tower will sway, causing multiple cables to rub against each other and get damaged. Therefore, a cable protection device is needed to protect and fix the cable to prevent the cables from rubbing against each other due to excessive shaking caused by strong wind, resulting in damage to the cable sheath and thus losing the protection for the inside of the cable.

[0055] Although the cables of a wind turbine can be fixed inside the tower barrel through fixing devices, the fixing devices rigidly fix the cables. When encountering strong winds, the cables will shake repeatedly, resulting in repeated friction between the cables, causing damage to the sheaths on the cable surfaces, and thus leading to fractures inside the cables, affecting the normal use of the cables.

[0056] A cable protection device for a wind turbine provided in this application aims to solve the above technical problems in the prior art, where the cables are worn and fractured due to shaking and pulling, affecting the normal use of the cables. Through the clamping and buffering components in the mounting plate, the cables can be clamped and protected to ensure that the cables will not be pulled and damaged when shaking; one or more annular plates are provided to clamp the cables to ensure that the cables will not collide with each other when shaking, thus preventing the cables from being worn.

[0057] The following will specifically describe the technical solutions of this application and how the technical solutions of this application solve the above technical problems in detail with specific embodiments. These specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the drawings.

[0058] Figure 1 It is a front view structural schematic diagram of the cable protection device for a wind turbine provided in this application; Figure 2 It is a rear view structural schematic diagram of the cable protection device for a wind turbine provided in this application.

[0059] As Figure 1 and Figure 2 shown, the cable protection device includes: a mounting plate 1 and an annular plate 4; independent and spaced strip-shaped grooves are provided inside the mounting plate 1; a clamping and buffering component 3 is provided in each strip-shaped groove;

[0060] The mounting plate 1 and the annular plate 4 are used in cooperation. Independent and spaced strip-shaped grooves are provided in the mounting plate 1, and a clamping and buffering component 3 is provided in each strip-shaped groove; among them, the clamping and buffering component 3 in the strip-shaped groove of the mounting plate 1 can provide a buffering effect during the pulling process of the cable 2 to prevent the cable 2 from being pulled and broken; while the annular member 4 fixes the cable to avoid the cable 2 from colliding due to shaking, causing friction and damage to its surface.

[0061] Those skilled in the art can understand that one or more annular plates 4 can be provided;

[0062] When the length of the cable 2 is short, one annular plate 4 can be provided. In this way, both the mounting plate 1 and the annular plate 4 are one, and the distance between the mounting plate 1 and the annular plate 4 can be set by those skilled in the art according to the actual situation, and this application does not make any limitations;

[0063] When the length of the cable 2 is relatively long, multiple annular plates 4 can be provided, and the distance between each annular plate can be set by the operator. In this way, one mounting plate 1 and multiple annular plates 4 are used to fix the cable 2, thereby preventing the cable from shaking and colliding and being damaged.

[0064] Figure 3 Schematic diagram of the connection structure of the mounting plate of the cable protection device for a wind turbine provided by the present application Figure 4 Schematic diagram of the clamping and buffering assembly structure of the cable protection device for a wind turbine provided by the present application. Combining Figure 3 and Figure 4 As shown, the clamping and buffering assembly 3 includes a sliding plate 301, telescopic parts symmetrically arranged on both sides of the sliding plate 301, and symmetrically arranged buffer pads 307; one end of the sliding plate 301 is fixedly connected to one end of the telescopic part; the other end of the sliding plate 301 contacts the buffer pad 307; the other end of the telescopic part contacts the inner wall of the strip-shaped groove of the mounting plate;

[0065] Furthermore, the clamping and buffering assembly 3 includes a sliding plate 301, which can slide freely in the strip-shaped groove. Telescopic parts and buffer pads 307 are symmetrically arranged on both sides of the sliding plate 301. Among them, the telescopic part can be a spring telescopic component, a hydraulic telescopic component, etc. The buffer pads 307 and the telescopic components are arranged on both sides of the sliding plate 301, avoiding rigid collision between the sliding plate 301 and the mounting plate 307 and causing damage to it; one end of the sliding plate 301 is fixedly connected to the telescopic part, the other end of the sliding plate 301 contacts the buffer pad 307, and the sliding plate 301 and the buffer pad 307 are detachably connected; the other end of the telescopic part contacts the inner wall of the strip-shaped groove of the mounting plate.

[0066] A clamping hole is provided in the middle of the sliding plate 301 for clamping one end of the cable 2;

[0067] In order to better fix the cable 2, a clamping hole is provided in the middle position of the sliding plate 301, so that the cable 2 can pass through the clamping hole into the sliding plate 301, and then the cable 2 is clamped and fixed.

[0068] Buffer holes that can deform are arranged at intervals inside the annular plate 4, and the other end of the cable 2 is arranged in the buffer holes. The cable 2 can pass through the buffer holes, and in order to clamp and fix the passing cable 2, the provided buffer holes can deform, so that the cable 2 can pass through the annular plate 4 and at the same time clamp the cable 2.

[0069] In the specific implementation process, the clamping holes in the middle of the sliding plate 301 correspond to each other, and there are corresponding holes on the mounting plate 1. The cable 2 is passed through this hole, then through the clamping hole and another corresponding hole on the mounting plate 1, and the cable is clamped by the clamping hole. The cable 2 is on one side of the buffer pad 307 and is in a bent state. In this way, when the sliding plate 301 slides towards the telescopic part side, the cable 2 on the buffer pad side 301 can be extended and stretched, further preventing the cable 2 from being damaged when the sliding plate 301 slides; when installing the annular plate 4, after a certain distance from the mounting plate 1, the cable 2 is passed through the buffer hole of the annular plate 4; when multiple annular plates 4 need to be installed, after a certain distance from the mounting plate 1, at a certain length, multiple annular plates 4 can be installed at a fixed distance and evenly to protect the cable 2.

[0070] The embodiment of the present application provides a cable protection device for a wind turbine, which includes a mounting plate and an annular plate; independent and spaced strip-shaped grooves are arranged in the mounting plate; a clamping and buffering assembly is arranged in each strip-shaped groove; the clamping and buffering assembly includes a sliding plate, telescopic parts symmetrically arranged on both sides of the sliding plate, and buffer pads symmetrically arranged; one end of the sliding plate is fixedly connected to one end of the telescopic part; the other end of the sliding plate contacts the buffer pad; the other end of the telescopic part contacts the inner wall of the strip-shaped groove of the mounting plate; a clamping hole is arranged in the middle of the sliding plate, and the clamping hole is used for clamping one end of the cable; buffer holes that can deform are arranged at intervals inside the annular plate, and the other end of the cable is arranged in the buffer holes. The cable protection device of the present application effectively avoids problems such as the cable being damaged due to shaking caused by the influence of wind, etc., through the coordinated cooperation of the mounting plate and the annular plate, which causes the cable to be pulled, collided, rubbed, etc.

[0071] Continuing to combine Figure 3 and Figure 4 As shown, a circular hole is arranged in the middle of the sliding plate 301, and a lower arc-shaped clamping plate 302 and an upper arc-shaped clamping plate 303 are also arranged in the circular hole;

[0072] The lower arc-shaped clamping plate 302 and the upper arc-shaped clamping plate 303 are arranged opposite to each other to form a clamping hole.

[0073] In order to enable the cable 2 to pass through the sliding plate 301 and clamp the cable 2, a circular hole can be opened in the middle of the sliding plate 301. In this way, the cable 2 can pass through the sliding plate 301.

[0074] Specifically, after ensuring that the cable 2 passes through the sliding plate 301, the cable 2 can still be clamped and fixed. A lower arc-shaped clamping plate 302 and an upper arc-shaped clamping plate 303 are arranged in the circular hole of the sliding plate 301. The lower arc-shaped clamping plate 302 and the upper arc-shaped clamping plate 303 are arranged opposite to each other to form a clamping hole. The cable 2 can pass through the clamping hole, and the lower arc-shaped clamping plate 302 and the upper arc-shaped clamping plate 303 are used to clamp the cable 2.

[0075] Optionally, the lower arc-shaped clamping plate 302 and the upper arc-shaped clamping plate 303 can move relative to each other to clamp the cable 2. In this embodiment, there is no limitation on the conditions for the lower arc-shaped clamping plate 302 and the upper arc-shaped clamping plate 303 to move towards each other. A spring can be independently arranged at one end of the lower arc-shaped clamping plate 302 and the upper arc-shaped clamping plate 303 respectively, so that the lower arc-shaped clamping plate 302 and the upper arc-shaped clamping plate 303 move towards each other. It can also be that through an arc-shaped clamp, the lower arc-shaped clamping plate 302 and the upper arc-shaped clamping plate 303 move towards each other under the clamping of the arc-shaped clamp.

[0076] In a specific example, please continue to refer to Figure 4 As shown, a threaded rod 304 is threadedly connected to the upper end of the sliding plate 301 in the mounting plate 1; the threaded rod 304 abuts against the upper arc-shaped clamping plate 303; when the threaded rod 304 rotates, the upper arc-shaped clamping plate 303 can be moved to press against the lower arc-shaped clamping plate 302 to clamp the cable 2.

[0077] A threaded rod 304 is threadedly connected to the upper end of the sliding plate 301, and the threaded rod 304 abuts against the upper arc-shaped clamping plate 303. The lower arc-shaped clamping plate 302 can be fixed in the circular hole of the sliding plate 301 or detachably arranged in the circular hole of the sliding plate 301; in this embodiment, there is no limitation on the setting of the lower arc-shaped clamping plate 302 in the circular hole of the sliding plate 301, as long as it can ensure that the lower arc-shaped clamping plate 302 and the upper arc-shaped clamping plate 303 move towards each other to clamp the cable 2;

[0078] The threaded rod 304 can rotate spirally on the sliding plate 301. During the rotation process, the upper arc-shaped clamping plate 303 in contact with it can be moved, so that the upper arc-shaped clamping plate 303 presses against the lower arc-shaped clamping plate 302 to clamp the cable 2.

[0079] Anti-slip pads are installed on both sides of the upper arc-shaped clamping plate 303 and the lower arc-shaped clamping plate 302 that form the clamping hole.

[0080] In order to better protect the cable 2 from damage, when the upper arc-shaped clamping plate 303 and the lower arc-shaped clamping plate 302 clamp the cable 2, anti-slip pads are installed on both sides of the upper arc-shaped clamping plate 303 and the lower arc-shaped clamping plate 302 that form the clamping hole, so as to prevent the cable 2 from sliding in the clamping hole formed by the upper arc-shaped clamping plate 303 and the lower arc-shaped clamping plate 302 after being pulled, thereby preventing the clamping hole from sliding when the cable 2 is pulled, and at the same time playing a protective role for the cable 2.

[0081] Please continue to refer to Figure 4 As shown, the telescopic part provided in this embodiment includes a telescopic sleeve rod 305 and an elastic member 306; the free end of the telescopic sleeve rod 305 is fixedly connected to the sliding plate 301;

[0082] Further, the telescopic part includes a telescopic sleeve rod 305 and an elastic member 306. Among them, the free end of the telescopic sleeve rod 305 is fixedly connected to the sliding plate 301. When the telescopic sleeve rod 302 slides freely on the sliding plate 301, it can telescopically extend and retract freely, and the elastic member 306 functions to buffer and prevent collision with the inner wall of the mounting plate 1, thereby preventing damage to the sliding plate 301 or the mounting plate 1.

[0083] The elastic member 306 is sleeved outside the telescopic sleeve rod 305, and one end of the elastic member 306 is fixedly connected to the sliding plate 301.

[0084] The elastic member 306 can be a spring, an elastic bracket, an elastic washer, etc. Among them, the elastic member 306 is sleeved outside the telescopic rod 305, and one end of the elastic member 306 is fixedly connected to the sliding plate 301. In this way, the telescopic rod 305 is sleeved inside the elastic member 306 to prevent the elastic member 306 from deviating from the strip-shaped groove when not under pressure, and thus it cannot play the corresponding protective role.

[0085] In the specific implementation process, when the cable 2 is not installed initially, the threaded rod 304 rotates and rotates on the sliding plate 301. During the rotation, the upper arc-shaped clamping plate 303 in contact with it can move upward, and the clamping hole becomes larger, making it easier for the cable 2 to pass through. After the cable 2 passes through, rotate the threaded rod 304 to make the upper arc-shaped clamping plate 303 move downward to clamp the cable 2, completing the installation process. In this way, when the cable is affected by strong winds or the like and the cable shakes, it can better protect the cable from being pulled and broken, as well as damaged by collision and friction, and at the same time, it also ensures that the protection device itself will not damage the cable.

[0086] Figure 5 Schematic diagram of the annular plate connection structure of the wind turbine cable protection device provided by this application; Figure 6 Schematic partial cross-sectional structure diagram of the square block and the T-shaped plate of the wind turbine cable protection device provided by this application. In another embodiment, as Figure 5 and 6 shown, symmetrically installed in the annular plate 4 are movable T-shaped clamping plates 5, and one end of the T-shaped clamping plate 5 is fixedly installed with an airbag 6; the airbag 6 and the inner wall of the annular plate 4 form a buffer hole, and the movement of the T-shaped clamping plate 5 makes one end of the airbag 6 contact the cable 2.

[0087] Symmetrically installed in the annular plate 4 are movable T-shaped clamping plates 5, and the T-shaped clamping plates 5 can move towards each other in the annular plate 4. To ensure that the T-shaped clamping plates 5 can better clamp the cable 2, an airbag 6 is fixedly installed at one end of the T-shaped clamping plate 5, and the airbag 6 and the inner wall of the annular plate 4 form a buffer hole. In this way, the cable 2 can pass through the buffer hole, and the T-shaped clamping plate 5 moves, and the airbag 6 clamps the cable 2 in the buffer hole.

[0088] The T-shaped clamping plate 5 moves so that one end of the airbag 6 contacts the cable 2. Besides playing a role in protecting the cable 2 from damage, the airbag 6 also prevents the cable 2 from sliding in the buffer hole.

[0089] A square block 7 is also arranged inside the annular plate 4; the square block 7 is arranged at the middle position inside the annular plate 4; the square block 7 is provided with a mounting groove; the T-shaped clamping plates 5 are symmetrically arranged on both sides of the square block 7; one end of the T-shaped clamping plate 5 is detachably inserted into the mounting groove.

[0090] Furthermore, a square block 7 is also arranged inside the annular plate 4, and the square block 7 is arranged at the middle position on the back of the annular plate 4. The T-shaped clamping plates 5 are respectively and independently located on both sides of the square block 7, and the square block 7 is provided with a mounting groove. One end of the two T-shaped clamping plates 5 is independently and detachably inserted into the mounting groove, and one end of the T-shaped clamping plate 5 can move freely in the mounting groove.

[0091] Certainly, in a possible implementation manner, a pushing structure such as a gear and a chain can be arranged in the mounting groove, mainly to push the T-shaped clamping plates 5 on both sides of the square block 7 to move freely in the mounting groove, so as to realize the functions of clamping and loosening the cable 2.

[0092] A bidirectional lead screw 8 is also arranged in the mounting groove. The bidirectional lead screw 8 is threadedly connected with the T-shaped clamping plate 5.

[0093] Furthermore, a bidirectional lead screw 8 is arranged in the mounting groove. The bidirectional lead screw 8 is threadedly connected with the T-shaped clamping plate 5, and the bidirectional lead screw 8 can rotate to push the T-shaped clamping plate 5 to move freely.

[0094] A turbine 9 is arranged at the middle position of the bidirectional lead screw 8; a worm 10 is arranged on one side of the mounting groove; the bidirectional lead screw 8 is fixedly connected with the turbine 9; the worm 10 is detachably connected with the square block 7; the turbine 9 and the worm 10 are meshed with each other.

[0095] Even further, a turbine 9 is arranged at the middle position of the bidirectional lead screw 8, and a worm 10 is arranged on one side of the mounting groove. The bidirectional lead screw 8 is fixedly connected with the turbine 9, and the worm 10 can be detachably connected with the square block 7 through threads, pins, etc., and the turbine 9 and the worm 10 are meshed with each other.

[0096] In the specific implementation process, rotate the worm 10, and then the turbine 9 rotates the bidirectional lead screw 8 to move the T-shaped clamping plate 5 and drive the airbag 6 to move. Pass the cable 3 through the buffer hole, and then rotate the worm 10 again, so that the T-shaped clamping plate 5 and the airbag 6 move to clamp the cable 2, completing the installation. This can ensure that the device clamps the cable without damaging the cable, and can also prevent the cable from shaking due to the influence of wind force and the cables from colliding with each other and being damaged.
