Problems solved by technology

[0003] At present, there are usually two methods for the detection of insulators in China. One is the traditional detection method of manual high-altitude operations. After the maintenance team members drive to the site with detection instruments, they board the tower to detect the operating status of all insulators one by one. The method is labor-intensive, the detection efficiency is low, and the operator has certain safety risks when the live detection is carried out; the other is to use mechanical equipment to automatically detect the insulator, which effectively reduces the danger of manual work. In recent years, scientific research personnel A variety of insulator detection robots have been developed to comprehensively evaluate the operating status of insulators and discover potential problems, which is of great significance to the stability of power transmission and the development of the national economy. However, the commonly used robots currently exist: complex structures, And most of them are one-piece structure, which cannot be disassembled, which is not conducive to the operator's carrying and installation, and cannot effectively adapt to the testing environment of the insulator; and the walking device of the robot mostly uses rollers, so that the robot and the surface of the insulator are in rolling contact. The guiding mechanism is usually a plate-shaped structure, which is in rigid contact with the insulator during the guiding process, which will cause wear on the surface of the insulator, and it is difficult to adapt to the error of the insulator string; it can only walk in a single direction along the insulator string, and cannot perform reciprocating motion. After the detection of insulators, there are still shortcomings such as manual recycling.
