[0002] Insulators are devices installed between conductors of different potentials or between conductors and ground potential components, which can withstand voltage and mechanical stress. It is a special insulating control component that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on telegraph poles, and gradually developed into high-type high-voltage wire connection towers with many disc-shaped insulators hung on one end. It is to increase the creepage distance. It is usually made of glass or ceramic, which is called an insulator. Insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions, otherwise the insulator will not play a significant role, which will damage the use and operation life of the entire line.

[0003] For example, a patent entitled "An Insulator Non-Contact Fault Inspection Device" (patent application number: CN201720006472.7) discloses an insulator non-contact fault inspection device. By means of a monitoring module arranged on a rail trolley, sound waves are collected by a wave collector, and the sound waves are converged onto a coaxial high-frequency sensor to accurately monitor in which direction the insulator has a problem. Non-contact monitoring of insulator faults can be achieved. However, the transmission line is long, and the rail trolley needs a certain amount of time to detect the condition of a single insulator, which is not conducive to rapid detection. In addition, when the transmission line is long, the rail trolley also needs energy to drive it, and the cost of use is relatively high.

[0004] Therefore, it is necessary to propose an intelligent robot system for UHV line insulator detection to solve the above problems. Utility Model Content
