Description

Technical Field

[0001] This utility model relates to the field of power transmission line maintenance, specifically a device for attaching and detaching grounding wires for power transmission lines. Background Technology

[0002] In power system inspection and maintenance operations, the installation and removal of grounding wires is a crucial step in ensuring the personal safety of workers. The reliability and convenience of this operation directly affect the safety and efficiency of power operations.

[0003] Traditional grounding wire mounting devices mostly use simple clips or hooks, which are prone to loosening or even falling off in complex environments (such as strong winds and vibrations), failing to provide reliable safety for maintenance personnel. For example, when performing power maintenance in mountainous areas or other windy regions, traditional devices may detach from the transmission line due to wind, causing the grounding wire to fail and seriously threatening the lives of workers. Furthermore, the disassembly process of existing devices is cumbersome and poses safety hazards. Traditional grounding wire mounting and disassembly devices often require workers to climb to high altitudes and manually remove the fixing structure, which not only consumes a lot of physical strength but also increases the risk of accidents such as falls from heights. Especially in severe weather conditions, the difficulty of manual disassembly at heights increases significantly, prolonging power outage time and affecting the stability of power supply. Therefore, it is necessary to design a grounding wire mounting and disassembly device for transmission lines to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a device for attaching and detaching ground wires in power transmission lines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for attaching and detaching ground wires for power transmission lines, comprising a mounting frame, two swing plates rotatably mounted inside the mounting frame, a clamping block fixedly connected to the top of each swing plate, and an elastic element provided between the two swing plates;

[0006] The bottom of the two swing plates is connected to a grounding wire body for grounding. A movable sleeve is fitted on the outside of the grounding wire body. A first pull rope is connected to one side of the clamping block. One end of the first pull rope is connected to the outside of the movable sleeve. Guide components for guiding the first pull rope are provided on both sides of the mounting frame. A second pull rope is connected to the outside of the movable sleeve.

[0007] Preferably, the guide assembly includes a mounting plate, which is fixedly mounted on the side of the mounting frame, and a limit ring is fixedly mounted on one side of the mounting plate, with the first pull rope passing through the limit ring.

[0008] Preferably, both the second pull rope and the first pull rope are made of nylon braided thread.

[0009] Preferably, the elastic element is a spring, which is fixedly connected between the two swing plates.

[0010] Preferably, a grip plate is fixedly installed at the bottom of the swing plate, and the grip plate is made of PVC material.

[0011] Preferably, both the swing plate and the clamping block are made of copper.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This power transmission line grounding wire attaching and detaching device is used by holding two grip plates close together. The grip plates drive the swing plate and clamping blocks to rotate, causing the two clamping blocks to open. Then, the two clamping blocks are placed on the outside of the power transmission line. After slowly releasing the grip plates, the elasticity of the spring pulls the two swing plates close together, thereby causing the two clamping blocks to clamp on the outside of the power transmission line, completing the connection between the device and the power transmission line. The two clamping blocks remain clamped on the outside of the power transmission line, thereby preventing relative slippage between the device and the power transmission line, ensuring connection stability, and improving the wind resistance of the device.

[0014] 2. When the grounding wire removal device for the transmission line needs to be removed, the second pull rope is pulled, which causes the moving sleeve to move downward along the outside of the grounding wire body. The grounding wire body drives the two first pull ropes to pull the clamps to rotate, causing the two clamps to open and thus disengage from the outside of the transmission line, completing the removal work. There is no need to climb to the grounding wire hanging position to remove the grounding wire, which improves the efficiency of removing the grounding wire. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please refer to Figure 1-3 As shown, this utility model provides a device for attaching and removing ground wires on power transmission lines, including a mounting frame 1. Two swing plates 2 are rotatably mounted inside the mounting frame 1. A clamping block 5 is fixedly connected to the top of the swing plates 2. An elastic element is provided between the two swing plates 2.

[0022] The bottom of the two swing plates 2 is connected to a grounding wire body 6 for grounding. A movable sleeve 10 is sleeved on the outside of the grounding wire body 6. A first pull rope 9 is connected to one side of the clamp block 5. One end of the first pull rope 9 is connected to the outside of the movable sleeve 10. Guide components for guiding the first pull rope 9 are provided on both sides of the mounting frame 1. A second pull rope 11 is connected to the outside of the movable sleeve 10.

[0023] Specifically, the tension applied to the swing plate 2 by the elastic element ensures that when the clamping block 5 is fitted on the outside of the transmission line, it has a clamping force on the transmission line, thus ensuring the stability of the device position.

[0024] The guide component includes a mounting plate 7, which is fixedly installed on the side of the mounting frame 1. A limit ring 8 is fixedly installed on one side of the mounting plate 7. A first pull rope 9 passes through the limit ring 8. When the first pull rope 9 passes through the limit ring 8, the moving sleeve 10 pulls the first pull rope 9 downward. The limit ring 8 can effectively change the direction of the upper pull force of the first pull rope 9, which makes it easier for the two clamps 5 to open.

[0025] Among them, the second pull rope 11 and the first pull rope 9 are both made of nylon braided thread, which has good toughness and insulation, and can prevent workers from being electrocuted.

[0026] Specifically, the elastic element is a spring 4, which is fixedly connected between two swing plates 2. The two clamps 5 are placed on the outside of the transmission line. Under the elastic action of the spring 4, the two swing plates 2 are pulled closer to each other, thereby causing the two clamps 5 to be clamped outside the transmission line.

[0027] Among them: the bottom of the swing plate 2 is fixedly installed with a grip plate 3, which is made of PVC material. By holding the grip plate 3, the rotation of the swing plate 2 and the clamping block 5 can be controlled, and the grip plate 3 has good insulation performance.

[0028] The swing plate 2 and the clamping block 5 are both made of copper. The swing plate 2, the clamping block 5, and the grounding wire body 6 are connected to each other, thus ensuring the protective effect of the device.

[0029] Working principle: This utility model is a device for attaching and detaching grounding wires for power transmission lines. When in use, hold the two grip plates 3 and bring them close together. The grip plates 3 drive the swing plate 2 and the clamping block 5 to rotate, causing the two clamping blocks 5 to open. Then, put the two clamping blocks 5 on the outside of the power transmission line. After slowly releasing the grip plates 3, under the elastic action of the spring 4, pull the two swing plates 2 closer together, thereby driving the two clamping blocks 5 to clamp the outside of the power transmission line, completing the connection between the device and the power transmission line. The staff below can then electrically connect the lower end of the grounding wire body 6 to the grounding component to complete the grounding of the power transmission line. Under the tension of the spring 4, the two clamping blocks 5 continue to clamp the outside of the power transmission line, thereby preventing relative sliding between the device and the power transmission line, ensuring connection stability, and improving the wind resistance of the device.

[0030] When it is necessary to remove the device, pull the second pull rope 11, which will cause the moving sleeve 10 to move downward along the outside of the grounding wire body 6. The grounding wire body 6 will drive the two first pull ropes 9 to pull the clamp 5 to rotate, so that the two clamps 5 open and the clamps 5 are separated from the outside of the transmission line, thus completing the disassembly work. There is no need to climb to the grounding wire hanging position to remove the grounding wire, which improves the efficiency of removing the grounding wire.
