Description

Power maintenance and cleaning equipment Technical Field

[0001] This utility model belongs to the field of power equipment technology, specifically referring to a power maintenance and cleaning device. Background Technology

[0002] With the rapid development of the power industry, the number of power equipment has surged, making its maintenance increasingly urgent. During operation, power equipment is prone to accumulating dust, dirt, bird droppings, and other contaminants on its surface, which not only affects its appearance but may also cause malfunctions or short circuits due to poor heat dissipation and decreased insulation performance.

[0003] Traditional power line maintenance cleaning devices often rely on manual dragging or a single roller drive. Due to the small contact area between the roller and the power line and insufficient friction, the roller is prone to slipping and shifting on inclined or curved lines, resulting in low cleaning efficiency and a high risk of missed areas. In addition, the clamping structure of traditional devices is mostly a fixed design, requiring repeated disassembly and reassembly of tools when installing power lines, which is cumbersome and complex, seriously affecting cleaning efficiency. Summary of the Invention

[0004] To address the problems of slippage during movement caused by insufficient friction and cumbersome disassembly of the clamping structure in traditional power transmission line cleaning devices, this utility model provides a power maintenance cleaning device.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a power maintenance cleaning device, including a U-shaped support and a power transmission line, wherein a U-shaped cross-section support frame is fixed to the side of the U-shaped support, an L-shaped groove is provided on the support frame, and telescopic cylinders are symmetrically fixed to the two inner side walls of the top of the L-shaped groove. A semi-circular scraper is fixed to the piston end of the telescopic cylinder, and the two semi-circular scrapers are combined to form a circular scraper group with an inner diameter that gradually changes along the axial direction. The front end of the power transmission line is inserted into the circular scraper group, and it can be adjusted to open and close to cover the power transmission line.

[0006] A driving component is provided on the U-shaped support. A rectangular frame is provided at the bottom of the driving component. A clamping and moving component is fixed on the rectangular frame. The clamping and moving component includes rollers. Two sets of rollers are symmetrically arranged, and their top central axis rotates through the top of the rectangular frame. The bottom central axis of the rollers is rotated and set on the inner side wall of the support frame. The power transmission line passes through the rollers.

[0007] As a preferred technical solution of this utility model, the clamping and moving assembly further includes an L-shaped support rod fixed to the inner wall of the rectangular frame, a rotary motor fixed to the inner side of the L-shaped support rod, a synchronous pulley and a synchronous belt. The output end of the rotary motor is connected to the top of one of the rollers, the synchronous pulley is fixed to the top of the roller, and the synchronous belt is sleeved on the synchronous pulley.

[0008] As a preferred technical solution of this utility model, the driving assembly includes a drive motor fixed to the outer wall of the U-shaped support and a bidirectional lead screw rotatably disposed on the inner walls of both ends of the U-shaped support. The output end of the drive motor passes through the U-shaped support and is connected to the end of the bidirectional lead screw. The two ends of the bidirectional lead screw are respectively threadedly connected to a first lead screw pair and a second lead screw pair. The rectangular frame is symmetrically provided with two sets and is respectively fixed to the bottom of the first lead screw pair and the second lead screw pair.

[0009] As a preferred technical solution of this utility model, a first limiting rod is provided on the inner sidewalls of both ends of the U-shaped support. The first limiting rod is parallel to the bidirectional lead screw, and the side portions of the first lead screw pair and the second lead screw pair are respectively slidably sleeved on both ends of the first limiting rod.

[0010] As a preferred embodiment of this utility model, a connecting block is fixed to the top of the semi-circular scraper, a second limiting rod is horizontally fixed inside the L-shaped groove, and the top of the connecting block is slidably sleeved on the second limiting rod.

[0011] As a preferred embodiment of this utility model, the outer diameter of the roller first decreases and then increases along the axial direction to form a concave profile in the middle; a handle is fixed to the top of the U-shaped support.

[0012] Compared with the prior art, the present invention achieves the following beneficial effects by adopting the above structure:

[0013] 1. By coordinating the drive assembly and the clamping assembly, the drive motor, in conjunction with the bidirectional lead screw, controls the movement of the rectangular frame and controls the clamping and releasing of the rollers on the power transmission line. The friction between the rollers and the power transmission line enables the device to move smoothly along the power transmission line. At the same time, the concave contour of the rollers in the middle automatically centers the power transmission line through curved surface constraints, preventing offset or slippage. This significantly improves the stability of the device during movement and the reliability of clamping the power transmission line, solving the problems of slippage and inaccurate positioning during the movement of the cleaning device in the prior art.

[0014] 2. By combining the telescopic cylinder and the semi-circular scraper, the telescopic cylinder drives the semi-circular scraper to open and close, quickly clamping or releasing the power transmission line, improving installation efficiency without tools; combined with the bidirectional screw driving the rectangular frame to move in opposite directions and the rollers to hold the rear end of the power transmission line, efficient clamping and releasing under single motor drive is achieved, further reducing the complexity of operation.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] As shown in Figures 1-4, the power maintenance cleaning device provided by this utility model includes a U-shaped support 1; a handle 22 is fixed on the top of the U-shaped support 1 to facilitate manual handling of the device and improve the ease of use of the device; a U-shaped cross-section support frame 2 is fixed on the side of the U-shaped support 1; an L-shaped groove 3 is provided on the support frame 2; telescopic cylinders 4 are symmetrically fixed on the two inner side walls of the top of the L-shaped groove 3; a semi-circular scraper 5 is fixed on the piston end of the telescopic cylinder 4; two semi-circular scrapers 5 are combined to form a circular scraper group 6 with an inner diameter that gradually changes along the axial direction; the front end of the power transmission line 23 is inserted into the circular scraper group 6, and it can be adjusted to open and close to cover the power transmission line 23; the inner diameter of the circular scraper group 6 is tapered and gradually changes along the axial direction of the power transmission line; the inner diameter of the small port matches the outer diameter of the power transmission line 23, so that it can fit tightly against its surface; the large port is convenient for removing dirt, foreign objects, etc. from the surface of the power transmission line 23.

[0024] A driving assembly 7 is provided on the U-shaped support 1. A rectangular frame 8 is provided at the bottom of the driving assembly 7. A clamping and moving assembly 9 is fixed on the rectangular frame 8. The clamping and moving assembly 9 includes rollers 10. Two sets of rollers 10 are symmetrically arranged, and their top central axis rotates through the top of the rectangular frame 8. The bottom central axis of the rollers 10 is rotated and set on the inner side wall of the support frame 2. The power transmission line 23 passes between the rollers 10. The outer diameter of the rollers 10 first decreases and then increases along the axial direction, forming a concave profile in the middle. The curved surface constraint makes the rollers 10 more flexible and stable. The transmission line 23 is embedded in the groove to achieve automatic centering, and the contact pressure increases the friction to stabilize the clamping and drive the device to move along the transmission line 23. After the device is installed on the transmission line 23, the circular scraper group 6 surrounds the transmission line 23, and the telescopic cylinder 4 drives the two semi-circular scrapers 5 to close by telescopically driving them, clamping the transmission line 23 in the circular scraper group 6 to clean foreign objects from its surface. The driving component 7 cooperates with the clamping and moving component 9 to move the device along the transmission line 23 to complete the cleaning of the transmission line 23.

[0025] As shown in Figures 1-4, the clamping and moving assembly 9 also includes an L-shaped support rod 11 fixed to the inner wall of the rectangular frame 8, a rotary motor 12 fixed to the inner side of the L-shaped support rod 11, a synchronous pulley 13, and a synchronous belt 14. The output end of the rotary motor 12 is connected to the top of one of the sets of rollers 10. The synchronous pulley 13 is fixed to the top of the rollers 10, and the synchronous belt 14 is sleeved on the synchronous pulley 13. When the rotary motor 12 is started, the synchronous pulley 13 and the synchronous belt 14 drive the two sets of rollers 10 at the bottom of the rectangular frame 8 to rotate synchronously. Stable movement is achieved by the friction between the power transmission line 23 and the rollers 10. At the same time, the clamping force of the rollers 10 evenly fixes the power transmission line 23 to prevent it from slipping during movement.

[0026] As shown in Figures 1-4, the driving assembly 7 includes a drive motor 15 fixed to the outer wall of the U-shaped support 1 and a bidirectional lead screw 16 rotatably mounted on the inner walls of both ends of the U-shaped support 1. The output end of the drive motor 15 passes through the U-shaped support 1 and is connected to the end of the bidirectional lead screw 16. The two ends of the bidirectional lead screw 16 are respectively threaded with a first lead screw pair 17 and a second lead screw pair 18. Two sets of rectangular frames 8 are symmetrically arranged and fixed to the bottom of the first lead screw pair 17 and the second lead screw pair 18 respectively. The power transmission line 23 passes between the four sets of rollers 10 at the bottom of the two sets of rectangular frames 8. When the drive motor 15 is started, the bidirectional lead screw 16 is driven to rotate, thereby driving the drive assembly 7 to rotate. The relative or opposite movement of the first lead screw pair 17 and the second lead screw pair 18 drives the synchronous movement of the rectangular frame 8, thereby achieving the clamping and loosening of the transmission line 23. The inner sidewalls of both ends of the U-shaped support 1 are provided with a first limiting rod 19, which is parallel to the bidirectional lead screw 16. The sides of the first lead screw pair 17 and the second lead screw pair 18 are respectively slidably sleeved on both ends of the first limiting rod 19. The first limiting rod 19 can provide guidance and limiting function for the first lead screw pair 17 and the second lead screw pair 18, ensuring that the rectangular frame 8 will not rotate or deviate during the movement, so that the device moves smoothly along the direction of the transmission line 23.

[0027] As shown in Figures 1-4, a connecting block 20 is fixed to the top of the semi-circular scraper 5, and a second limiting rod 21 is horizontally fixed in the L-shaped groove 3. The top of the connecting block 20 is slidably sleeved on the second limiting rod 21. The second limiting rod 21 can provide guidance for the movement of the semi-circular scraper 5, ensuring that it can only move towards or away from each other. When the piston of the telescopic cylinder 4 extends or retracts, it drives the semi-circular scraper 5 to move. The two semi-circular scrapers 5 can move closer or further away from each other, thereby realizing the clamping and releasing of the power transmission line 23.

[0028] In practical use, when installing the device on the transmission line 23, first insert the transmission line 23 into the L-shaped groove 3, and place the front end of the transmission line 23 between the two semi-circular scrapers 5. Start the telescopic cylinder 4, and the piston end pushes the semi-circular scrapers 5 to move towards each other along the second limit rod 21 until the inner wall of the circular scraper group 6 is tightly attached to the surface of the transmission line 23. Stable clamping is achieved by the pressure of the telescopic cylinder 4. Then, the drive motor 15 drives the bidirectional lead screw 16 to move the two sets of rectangular frames 8 towards each other, and the four sets of rollers 10 clamp the rear end of the transmission line 23. Then, start the rotary motor 12, and drive the rollers 10 to rotate through the synchronous pulley 13 and the synchronous belt 14. The device moves along the transmission line 23 by relying on the friction between the rollers 10 and the transmission line 23. At the same time, the circular scraper group 6 moves with the device to clean foreign objects from the surface of the transmission line 23. During the movement, the concave contour of the rollers 10 can automatically center the transmission line 23 to ensure smooth operation. After cleaning is completed, reverse the operation of the drive motor 15 and the telescopic cylinder 4 to disassemble the device.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
