Description

Technical Field

[0001] The utility model relates to the technical field of transmission line operation and maintenance devices, and specifically refers to a foreign object cleaning device for transmission line operation and maintenance and repair. Background Technique

[0002] Transmission lines are a crucial part of the power system, responsible for delivering the electric energy generated by power plants to various power consumption areas. These lines usually span vast geographical areas and are exposed to various natural environments. Due to their high erection height and wide distribution, once a fault occurs, it is difficult to repair. Therefore, effective operation and maintenance and repair are crucial. In cold climate conditions, foreign objects such as ice and snow are likely to accumulate on transmission lines. These foreign objects not only increase the load on the lines but may also cause serious consequences such as line breakage and tower collapse. Therefore, timely cleaning of foreign objects on transmission lines, especially ice and snow, is of great significance for ensuring the safe and stable operation of the power system. Currently, common foreign object cleaning methods include manual cleaning and mechanical cleaning, etc.

[0003] When traditional foreign object cleaning devices walk on the cables of transmission lines, their stability is poor. On the one hand, the design of the walking mechanism is not reasonable enough to effectively adapt to cables of different diameters, and it is easy to shake and deviate. On the other hand, there is a lack of an effective adjustment mechanism and it cannot be adjusted according to the actual situation of the cables, further affecting the walking stability.

[0004] Traditional foreign object cleaning devices usually do not have a special cable supporting function. During the process of knocking foreign objects, since the cables are not effectively supported, the cables are easily subjected to a large impact force, further exacerbating the shaking of the device and at the same time increasing the risk of damage to the lines.

[0035] The working principle of the foreign matter cleaning device for power transmission line operation and maintenance is as follows: the utility model mainly relies on the walking mechanism 3 to move on the power transmission line cable, and knocks and cleans the foreign matter on the cable through the knocking assembly 4. The upper groove wheel 5 and the adjustable lower groove wheel assembly 6 in the walking mechanism 3 cooperate to adapt to cables of different diameters and clamp the cables to ensure the stable movement of the device. The motor 8 drives the upper groove wheel 5 to rotate, driving the entire device forward. The knocking assembly 4 uses the motor 2 16 to drive the eccentric wheel 17 to rotate, so that the guide rod 12 drives the knocking plate 13 to move up and down to knock on the foreign matter on the cable. The supporting assembly 10 supports the cable when knocking to reduce shaking. The pull rod assembly 9 is connected to other cables to further improve the stability of the device.

[0036] The use process of the foreign matter cleaning device for power transmission line operation and maintenance is as follows:

[0037] 1. Preparation: Move the foreign matter cleaning device to the bottom of the power transmission line where foreign matter needs to be cleaned. Check whether all parts of the device are intact and ensure that the motor 8, electric push rod 28 and other equipment are operating normally. According to the diameter of the cable, adjust the height of the lower groove wheel assembly 6 by adjusting the bolt 22 so that the upper groove wheel 5 and the lower groove wheel 19 can tightly clamp the cable.

[0038] 2. Install the device: Align the opening 2 on one side of the device frame 1 with the cable, so that the cable enters the frame 1 and is located between the upper groove wheel 5 and the lower groove wheel 19. Adjust the support assembly 10 so that the roller 26 is located at an appropriate position below the cable, and adjust the height of the roller 26 through the electric push rod 28 to ensure that the roller 26 can effectively support the cable. Connect the safety hook 24 of the pull rod assembly 9 to other stable cables nearby to improve the stability of the device.

[0039] 3. Start the device: Turn on the motor 8, which drives the upper groove wheel 5 to rotate, driving the device to move forward along the cable. At the same time, turn on the motor 2 16, which drives the eccentric wheel 17 to rotate, and the eccentric wheel 17 pushes the limit plate 14, so that the guide rod 12 drives the knocking plate 13 to move up and down, knocking and cleaning the foreign matter on the cable.

[0040] 4. Cleaning process: When the device is moving, the knocking assembly 4 continuously knocks foreign objects on the cable. The roller 26 of the supporting assembly 10 rotates with the shape and movement of the cable, effectively supporting the cable and reducing shaking during knocking. The length of the electric push rod 28 can be adjusted according to actual conditions to ensure that the roller 26 can always support the cable well. At the same time, observe the movement of the device. If the movement is found to be unstable, check the clamping conditions of the upper groove wheel 5 and the lower groove wheel 19, and adjust them by adjusting the bolt 22.

[0041] 5. End of cleaning: After cleaning a section of cable, turn off motor 8 and motor 2 16. Unhook the safety hook 24 of the pull rod assembly 9 and remove the device from the cable. Inspect and maintain the device and prepare it for the next use. Clean the dust and debris on the surface of the device, check the wear of each component, and replace it in time if necessary. Maintain the motor 8, electric push rod 28 and other equipment to ensure their good performance.

[0042] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
