Description

Technical Field

[0001] The invention belongs to the technical field of cable line fault detection, and in particular relates to an overhead cable line fault detection device for a wind power station. Background Art

[0002] In recent years, with the continuous deepening of the reform of my country's power enterprises, the power supply scope has been continuously expanded, and the mileage of high-voltage cables in the power grid has been continuously increasing. In order to ensure the stable operation of the national power grid, a large number of maintenance personnel are fighting on the front line. At present, most high-voltage transmission cables are erected at high altitudes. During maintenance and fault repair, workers need to climb above the iron frames to work, and sometimes even need to patrol between the iron frames along the cables. Such maintenance work cannot get a good rest in the middle, and the physical requirements of the workers are extremely high. In addition, the attention of workers working at heights must be highly concentrated, which accelerates the physical consumption of the workers, making high-altitude work more dangerous. Accidents may occur if they are not careful. For this reason, countries are also actively developing troubleshooting robots that can replace workers' work. When the troubleshooting robot is troubleshooting on the high-voltage cable, due to the influence of wind, there may be debris such as kite lines and plastic bags on the high-voltage cable. When the troubleshooting robot passes by, the debris can easily get entangled in the moving wheels of the equipment, causing equipment failure and affecting the normal operation of the troubleshooting robot.

The swing arm 401 is symmetrically arranged on both sides of the support plate 1. The swing arm 401 cooperates with the fixed shaft 402 to drive the obstacle clearing knife 404 to move up and down, thereby clearing the debris on the cable line. The fixed shaft 402 is fixedly installed at one end of the support plate 1, and a strip hole 403 is opened in the middle of the swing arm 401. The fixed shaft 402 is arranged in the strip hole 403. The obstacle clearing knife 404 is arranged at one end of the swing arm 401. The obstacle clearing knife 404 is used to cut and clear the debris entangled on the cable line. The other end of the swing arm 401 is rotatably installed on the moving component 6.

[0055] The first cylinder 601 extends and pushes the sliding frame 602 to move along the mounting hole 101. During the movement of the sliding frame 602, it will push the other end of the second rotating rod 604 to move with the sliding frame 602. The hinge between one end of the second rotating rod 604 and the first rotating rod 603 will move upward, which will drive the other end of the swing arm 401 to move upward and follow the hinge between the first rotating rod 603 and the second rotating rod 604.

The paint bucket 203 is fixedly mounted on the top of the support rod 205. The setting of the holding mechanism 2 can store paint and facilitate the brush 307 to replenish paint, ensuring that the brush 307 can apply paint on the cable line, and ensuring that the marking mechanism 3 can mark the fault point on the cable line.

[0072] When the brush 307 on the marking mechanism 3 is in a vertical downward position, the fourth cylinder 201 is opened to drive the lifting plate 204 to move upward. The upward movement of the lifting plate 204 will drive the lifting rod 202 and the paint bucket 203 to move upward until the brush 307 penetrates into the paint bucket 203, thereby achieving the purpose of replenishing paint to the brush 307.

[0073] When the marking mechanism 3 needs to be used, it is only necessary to open the fourth cylinder 201 to drive the lifting plate 204 to move downward.
