Description

Technical Field

[0001] This utility model belongs to the field of power maintenance technology, and in particular relates to a device for attaching and removing grounding wires. Background Technology

[0002] In the daily maintenance and repair of power systems, installing grounding wires is a crucial safety measure. Its purpose is to ensure the safety of personnel working on de-energized equipment and prevent injury from sudden power restoration or induced current. However, traditional grounding wire installation methods have many problems that urgently need to be addressed.

[0003] Traditional grounding wire installation relies primarily on manual labor. Operators must carry the grounding wire and use climbing equipment such as ladders or scaffolding, or even climb poles to reach the cable and perform the installation. This method not only demands high levels of physical strength and skill from the operators but also poses significant safety risks. Because cables are typically located at high altitudes and may carry potential induced current, close contact with live cables can easily result in electric shock, seriously threatening personal safety. Utility Model Content

[0004] To achieve the above objectives, this utility model proposes a grounding wire hanging device, which includes a connecting plate. A hanging mechanism is fixedly installed on the side wall of the connecting plate. The hanging mechanism includes a hook, which is fixedly installed on the side wall of the connecting plate. A baffle is fixed on the side wall of the hook. A first limiting plate is provided above the baffle. A second limiting plate is provided above the first limiting plate. A fixing block is fixedly installed above the connecting plate. An electromagnet is fixedly installed inside the fixing block. An iron sheet is fixedly installed at the end of the electromagnet away from the connecting plate. An L-shaped connecting block is inserted into the fixing block. A first magnet is fixedly installed on the side wall of the L-shaped connecting block.

[0005] In one example, the first limiting plate is connected to the hook via a hinge.

[0006] In one example, the second limiting plate is connected to the hook via a hinge.

[0007] In one example, the electromagnet is fixedly mounted above the connecting plate.

[0008] In one example, the iron sheet is fixedly installed inside the fixing block.

[0009] In one example, a hanging ring is fixedly installed at the end of the hook away from the connecting plate.

[0010] In one example, a connecting rod is fixedly mounted on the end of the connecting plate away from the hook.

[0011] The grounding wire hanging device proposed in this utility model can bring the following beneficial effects:

[0012] 1. This utility model describes a grounding wire hanging device that works in conjunction with a drone. An L-shaped fixing block is fixed to the bottom of the drone and inserted into the fixing block to achieve a stable connection. The drone is used to lift the device above the cable for the wire hanging operation. Operators do not need to have close contact with the live cable, which greatly reduces the safety risks such as electric shock. Compared with the traditional manual grounding wire hanging method, it reduces manpower input and is not limited by terrain, height or other factors. It can quickly reach the designated location for operation, which significantly improves the convenience and work efficiency of grounding wire hanging.

[0013] 2. This utility model utilizes the coordinated operation of components such as the first limiting plate, the second limiting plate, the baffle, and the hook to automatically complete the hanging action after contacting the cable. When the cable passes through the flipped limiting plate and the hook contacts the cable and energizes it, the electromagnet springs away the first magnet, causing the L-shaped fixing block to be pulled out. The device flips due to gravity until the cable is locked in the appropriate position. The entire process requires no manual adjustment, improving the accuracy of hanging the cable. When removing the device, the cable can be slid out by hooking the hanging ring and pulling. The ingenious structural design, simple operation, and high reliability ensure the efficient and stable hanging of the grounding wire. Attached Figure Description

[0020] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0021] Example:

[0022] like Figures 1-4As shown, an embodiment of this utility model proposes a grounding wire hooking device, which includes a connecting plate 11. In use, an L-shaped connecting block 21 is fixed to the bottom of the drone, and the L-shaped connecting block 21 is inserted into the fixing block 16. A hook 12 is fixedly installed on the side wall of the connecting plate 11. A first magnet 19 will be firmly attracted to the side wall of the iron sheet 18. A baffle 13 is fixed on the side wall of the hook 12. At this time, a first limiting plate 14 will be placed on top of the baffle 13. A first limiting plate 14 is provided above the baffle 13. The first limiting plate 14 is connected to the hook 12 through a hinge. A second limiting plate 15 is placed on top of the first limiting plate 14. A second limiting plate 15 is provided above the first limiting plate 14. The second limiting plate 15 is connected to the hook 12 through a hinge.

[0023] A fixing block 16 is fixedly installed above the connecting plate 11. The ground wire is tied above the connecting rod 23. An electromagnet 17 is fixedly installed inside the fixing block 16. The electromagnet 17 is fixedly installed above the connecting plate 11. At this time, the drone lifts the device above the cable. An iron plate 18 is fixedly installed at the end of the electromagnet 17 away from the connecting plate 11. The iron plate 18 is fixedly installed inside the fixing block 16. The second limiting plate 15 and the first limiting plate 14 are rotated counterclockwise and clockwise, respectively. An L-shaped connecting block 21 is inserted into the fixing block 16. The cable will pass through the second limiting plate 15 and the first limiting plate 14. A first magnet 19 is fixedly installed on the side wall of the L-shaped connecting block 21. At this time, the hook 12 will contact the cable. The end of the hook 12 away from the connecting plate 11 is fixedly installed. The device is equipped with a hanging ring 22 and a hook 12 that transmits power to a connecting plate 11. A connecting rod 23 is fixedly installed on the end of the connecting plate 11 away from the hook 12. An electromagnet 17 is fixed above the connecting plate 11. When the electromagnet 17 is energized, the end of the electromagnet 17 connected to the iron plate 18 repels the first magnet 19. When energized, the electromagnet 17 pushes the first magnet 19 away. At this time, the first magnet 19 will no longer be attracted to the side wall of the iron plate 18. The drone can easily pull the L-shaped connecting block 21 out from the fixed block 16. At this time, due to the influence of gravity, the device will rotate counterclockwise. The device rotates until the cable is stuck between the hook 12 and the baffle 13 and tends to be stable. At this time, the first limiting plate 14 hangs down naturally and the second limiting plate 15 rests inside the hook 12.

[0024] When it is necessary to remove the device, use a drone to hook the hanging ring 22 and pull the hanging ring 22 from bottom to top. The hanging ring 22 will drive the entire device to move from bottom to top, and the cable will slide out of the hook 12 from the side wall of the second limiting plate 15, thus completing the removal of the device.

[0025] Working principle: When using the device, first fix the L-shaped connecting block 21 to the bottom of the drone, and then insert the L-shaped connecting block 21 into the fixed block 16. At this time, the first magnet 19 on the side wall of the L-shaped connecting block 21 will firmly adhere to the side wall of the iron plate 18 inside the fixed block 16, thereby stably connecting the device to the drone. At the same time, the first limiting plate 14 (the first limiting plate 14 is connected to the hook 12 by a hinge) is placed above the baffle 13 on the side wall of the hook 12. The second limiting plate 15 (the second limiting plate 15 is also connected to the hook 12 by a hinge) is placed above the first limiting plate 14. The entire device is in the initial state of being ready to work. Before this, the ground wire is tied above the connecting rod 23 to prepare for the subsequent grounding operation.

[0026] After connection, the drone hoists the device above the cable. Once it reaches the designated position, the second limiting plate 15 and the first limiting plate 14 rotate counterclockwise and clockwise respectively, allowing the cable to pass between them. Then, the hook 12 contacts the cable. Since the cable is energized, the hook 12 transmits power to the connecting plate 11. The electromagnet 17 fixed above the connecting plate 11 is energized by the connection plate 11. The end of the electromagnet 17 connected to the iron plate 18 repels the first magnet 19. After energization, the electromagnet 17... The first magnet 19 is popped away and no longer adheres to the side wall of the iron sheet 18. At this time, the drone can easily pull the L-shaped connecting block 21 out of the fixed block 16. After the L-shaped connecting block 21 is pulled out, the entire device will rotate counterclockwise due to gravity. As it rotates, the device will eventually stabilize at the position where the cable is stuck between the hook 12 and the baffle 13. At this time, the first limiting plate 14 hangs down naturally and the second limiting plate 15 rests inside the hook 12, completing the installation of the grounding wire on the cable and realizing the grounding function.

[0027] When it is necessary to remove the device, use the drone to hook the hook 12 at the end away from the connecting plate 11 and then pull the hook 22 from bottom to top. The upward movement of the hook 22 will drive the entire device upward together. During this process, the cable will slide out of the hook 12 from the side wall of the second limiting plate 15, thereby completing the device removal operation.
