A foreign object removal device for power transmission line testing

Abstract

This utility model discloses a foreign object removal device for power transmission line inspection, including a mounting base plate, a fixing plate fixedly mounted at the bottom of the mounting base plate, a flamethrower fixedly mounted on the left side of the fixing plate, a flipping component mounted at the top of the mounting base plate, a connecting shell mounted on the top of the mounting base plate via the flipping component, a moving component mounted inside the connecting shell, a mounting plate mounted on the top of the connecting shell via the moving component, a driving component mounted inside the mounting plate, and a rotating component mounted on the rear side of the connecting shell. When moving to a node of the power transmission line, the driving component and the rotating component move away from the side of the power transmission line node, reset, and make contact with the power transmission line, allowing the device to be removed from the power transmission line node. This avoids the need to reposition the climbing robot if it cannot pass through the power transmission line node, thus reducing the time required for foreign object removal.

Description

Technical Field

[0001] This utility model relates to the field of power transmission line testing technology, and in particular to a foreign matter removal device for power transmission line testing. Background Technology

[0002] Power transmission lines are constructed by using transformers to step up the voltage of electricity generated by generators, which is then transmitted to the power grid via circuit breakers and other control equipment. Structurally, power transmission lines are divided into overhead transmission lines and cable lines. Overhead transmission lines consist of poles, conductors, insulators, line hardware, guy wires, pole foundations, and grounding devices, and are erected above the ground. Based on the nature of the transmitted current, power transmission is divided into AC transmission and DC transmission. Overhead transmission lines consist of poles, conductors, insulators, line hardware, guy wires, pole foundations, and grounding devices, and are erected above the ground. Before inspection, power distribution network transmission lines typically require the removal of foreign objects from their surface.

[0003] When cleaning foreign objects on power transmission lines, climbing robots are usually used to walk on the power lines, in conjunction with cleaning mechanisms or flamethrowers to remove the foreign objects. However, there are connection nodes on the surface of the power transmission lines. When the climbing robot moves to a connection node, the presence of a mounting bracket at the node prevents the climbing robot from moving on the power line, requiring the climbing robot to be repositioned, which increases the time required for foreign object removal. Based on the above problems, this application proposes a foreign object removal device for power transmission line inspection. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a foreign object removal device for power transmission line testing, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A foreign object removal device for power transmission line inspection includes a mounting base plate, a fixing plate fixedly mounted on the bottom of the mounting base plate, a flamethrower fixedly mounted on the left side of the fixing plate, a flipping component mounted on the top of the mounting base plate, a connecting shell mounted on the top of the mounting base plate via the flipping component, a moving component mounted inside the connecting shell, a mounting plate mounted on the top of the connecting shell via the moving component, a driving component mounted inside the mounting plate, and a rotating component mounted on the rear side of the connecting shell.

[0008] Preferably, the movable component includes a drive motor fixedly mounted on the right side of the connecting housing, a worm gear fixedly mounted at the output end of the drive motor, a worm wheel meshing on the surface of the worm gear, a screw fixedly mounted inside the worm wheel, the screw rotatably mounted inside the connecting housing, a movable plate threaded on the surface of the screw, the movable plate slidably mounted inside the connecting housing, and a mounting plate fixedly mounted on the top of the movable plate.

[0009] Preferably, the drive assembly includes a rotary motor fixedly mounted on the rear side of the mounting plate, and a drive roller is fixedly provided at the output end of the rotary motor.

[0010] Preferably, the rotating assembly includes a mounting housing fixedly installed on the rear side of the connecting housing. A connecting shaft is rotatably arranged inside the mounting housing. A driving gear is fixedly arranged on the surface of the connecting shaft. A toothed plate is meshed on the surface of the driving gear. The toothed plate is fixedly installed on the rear side of the moving plate. A driven gear is meshed on the surface of the driving gear. A rotating shaft is fixedly arranged inside the driven gear. The rotating shaft is rotatably arranged inside the mounting housing. Connecting brackets are fixedly arranged at both ends of the rotating shaft. Limiting rollers are rotatably arranged inside the connecting brackets.

[0011] Preferably, a battery box is fixedly installed at the bottom of the mounting base plate, and a control box is fixedly installed at the front of the battery box.

[0012] Preferably, the number of driving rollers is three, which are arranged in a linear array, and the number of limiting rollers is six, with two limiting rollers forming a group.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the foreign object removal device for power transmission line inspection moves to the node of the power transmission line, the moving component drives the moving plate to move, so that the moving plate drives the driving component to separate from the power transmission line through the mounting plate, and drives the rotating component to separate from the power transmission line. The flipping component drives the moving plate to flip through the connecting shell, so that the mounting plate drives the driving component to make a circular motion, and drives the rotating component to flip through the connecting shell. When the driving component and the rotating component are removed from the side of the power transmission line node, and the driving component and the rotating component are reset and make contact with the power transmission line, they can be removed from the power transmission line node. This avoids the need to reposition the climbing robot when it cannot pass through the power transmission line node, and reduces the time for foreign object removal. Attached Figure Description

[0020] Reference Figure 1-4A foreign object removal device for power transmission line inspection includes a mounting base plate 1, a fixing plate 2 fixedly mounted on the bottom of the mounting base plate 1, a flamethrower 3 fixedly mounted on the left side of the fixing plate 2, a flipping assembly on the top of the mounting base plate 1, a connecting housing 8 connected to the top of the mounting base plate 1 via the flipping assembly, a moving assembly inside the connecting housing 8, a mounting plate 14 connected to the top of the connecting housing 8 via the moving assembly, a driving assembly inside the mounting plate 14, and a rotating assembly on the rear side of the connecting housing 8. The moving assembly includes components fixedly mounted on the connecting housing. The drive motor 9 on the right side of the housing 8 has a worm gear 10 fixedly mounted at its output end. A worm wheel 11 is meshed on the surface of the worm gear 10, and a screw 12 is fixedly mounted inside the worm wheel 11. The screw 12 is rotatably mounted inside the connecting housing 8, and a movable plate 13 is threaded onto its surface. The movable plate 13 is slidably mounted inside the connecting housing 8, and a mounting plate 14 is fixedly mounted on top of the movable plate 13. The drive motor 9 rotates the worm gear 10, worm wheel 11, and screw 12, causing the movable plate 13 to move the mounting plate 14 up or down. The rotary motor 15 drives the drive roller 16 to separate or contact with the power transmission line. The moving plate 13 drives the toothed plate 20 to push the drive gear 19 to drive the connecting shaft 18 to rotate. The drive gear 19 drives the rotating shaft 22 to rotate through the driven gear 21 that meshes with it. The rotating shaft 22 drives the connecting frame 23 to flip downward or upward, so that the connecting frame 23 drives the limiting roller 24 to separate or contact with the power transmission line. The flipping assembly includes a fixed frame 4 fixedly installed on the top of the mounting base plate 1. A servo motor 5 is fixedly installed on the right side of the fixed frame 4. A rotating shaft 6 is fixedly installed at the output end of the servo motor 5. A rotating plate 7 is fixedly installed on the surface of the rotating shaft 6. The connecting housing 8 is fixedly installed on the top of the rotating plate 7. The servo motor 5 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the connecting housing 8 to flip backward or forward through the rotating plate 7. The connecting housing 8 drives the mounting plate 14 to flip through the moving plate 13. The drive assembly and the rotating assembly flip backward or forward, which facilitates the drive assembly and the rotating assembly to move from the side of the power transmission line and facilitates the connection assembly to be vertically aligned with the power transmission line again after passing through the node.

[0021] Specifically, the drive assembly includes a rotary motor 15 fixedly mounted on the rear side of the mounting plate 14, with a drive roller 16 fixedly mounted at the output end of the rotary motor 15. The rotation assembly includes a mounting housing 17 fixedly mounted on the rear side of the connecting housing 8, with a connecting shaft 18 rotatably mounted inside the mounting housing 17. A drive gear 19 is fixedly mounted on the surface of the connecting shaft 18, and a toothed plate 20 meshes with the surface of the drive gear 19. The toothed plate 20 is fixedly mounted on the rear side of the moving plate 13. A driven gear 21 meshes with the surface of the drive gear 19, and a rotating shaft 22 is fixedly mounted inside the driven gear 21. The rotating shaft 22 is rotatably mounted inside the mounting housing 17, with connecting brackets 23 fixedly mounted at both ends of the rotating shaft 22. Limiting rollers are rotatably mounted inside the connecting brackets 23. The device has three drive rollers 16 arranged in a linear array, and six limit rollers 24 arranged in pairs. The limit rollers 24 and drive rollers 16 contact the power transmission line, clamping the power transmission line. The output end of the rotary motor 15 drives the drive rollers 16 to rotate, fixing them on the surface of the power transmission line. The moving plate 13 moves the connecting housing 8, which in turn moves the mounting housing 17 and the rotating shaft 22. The rotating shaft 22, through the connecting frame 23, drives the limit rollers 24 to roll on the power transmission line. When the device reaches an obstacle on the power transmission line, the flame is sprayed by the flamethrower 3 to burn the foreign objects wrapped around the surface of the power transmission line.

[0022] Specifically, a battery box 25 is fixedly installed at the bottom of the mounting base plate 1, and a control box 26 is fixedly installed at the front of the battery box 25. The battery in the battery box 25 provides the power required for operation, while the control box 26 facilitates the control of the foreign object removal device.

[0023] The foreign object removal device used for power transmission line inspection is connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0024] In use: When moving to the power transmission line node, the drive motor 9 drives the output end to rotate the worm gear 10. The worm gear 10 drives the screw 12 to rotate through the worm wheel 11 meshing with it. The screw 12 drives the moving plate 13 to move, causing the moving plate 13 to move the mounting plate 14 upward. This causes the rotary motor 15 to drive the drive roller 16 to separate from the power transmission line. The moving plate 13 drives the toothed plate 20 to move upward, causing the toothed plate 20 to push the drive gear 19 to drive the connecting shaft 18 to rotate. The drive gear 19 drives the rotating shaft 22 to rotate through the driven gear 21 meshing with it. This causes the rotating shaft 22 to drive the connecting frame 23 to flip downward, causing the connecting frame 23 to drive the limit roller 24 to separate from the power transmission line. The servo motor 5 drives the output end to rotate the rotating shaft 6. The rotating shaft 6 drives the connecting housing 8 to flip backward through the rotating plate 7. This causes the connecting housing 8 to flip the mounting plate 14 through the moving plate 13. This causes the rotary motor 15 to drive the drive roller 16 to perform a circular motion, while the connecting housing... 8. The mounting housing 17 drives the rotating shaft 22 to rotate, causing the connecting frame 23 to drive the limiting roller 24 to rotate. When the front drive roller 16 and the limiting roller 24 move away from the node, the servo motor 5 drives the rotating plate 7 to reset via the rotating shaft 6, causing the connecting housing 8 to reset the mounting plate 14 and the mounting housing 17, and then drives the connecting frame 23 to reset via the rotating shaft 22. This causes the connecting frame 23 and the rotating motor 15 to reset the drive roller 16 and the limiting roller 24. The drive motor 9... The worm gear 10 and worm wheel 11 drive the screw 12 to reverse, causing the moving plate 13 to drive the drive roller 16 to contact the power transmission line via the mounting plate 14 and the rotary motor 15. This causes the toothed plate 20 to drive the rotating shaft 22 to reverse via the connecting shaft 18 and the driven gear 21, causing the connecting frame 23 to drive the limiting roller 24 to contact the power transmission line. The subsequent operations pass through the power transmission line node in sequence, and each time a set of drive rollers 16 and a set of limiting rollers 24 separate from the power transmission line, so that the mounting base plate 1 can move stably.
