technical field

The invention relates to the technical field of power transmission lines, in particular to an intelligent maintenance device for power transmission lines.

Background technique

With the development of society, the demand for electricity is also increasing. The transmission of electricity is inseparable from the transmission line, and the construction of the transmission line will involve many equipment. The insulator is a particularly important part. The insulator is a special insulation Controls can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles. As the voltage level increased, the number of insulators used also increased and became insulator strings. The purpose of several insulators to form an insulator string is to increase the creepage distance. It is usually made of glass or ceramics. According to different installation methods, insulators can be divided into suspension insulators and post insulators. Suspension insulators are widely used in high-voltage overhead transmission lines and Insulation and mechanical fixation of flexible busbars in power generation and substations. In wet weather, dirty insulators are prone to flashover discharge, so they must be cleaned to restore the original insulation level. At the same time, it is necessary to regularly check whether the insulator has a low value or zero value. If it occurs, it needs to be replaced immediately. Otherwise, when the instantaneous short-circuit current generated by lightning strikes and pollution flashover is severe, it may cause overheating and explosion of low-value and zero-value insulators, resulting in series drop accidents, which pose a great threat to the safe operation of transmission lines.

In the prior art, the patent with the notification number CN114054400B provides an insulator cleaning device, which includes two shells that cooperate with each other.

A sealing part matched with the insulator is arranged in the connecting cylinder, a water pipe is arranged on the side plate, a cleaning ball containing cylinder is arranged on the water pipe, and cleaning balls are placed in the cleaning ball containing cylinder. The advantage is that the insulator to be cleaned is sealed and covered by two mutually matched shells, and then the cleaning water is injected into the shell, and the surface of the insulator is cleaned by the rotating cleaning roller, and the surface of the insulator is cleaned with the help of the cleaning ball. The dirt is washed down, and the cleaning effect is good. But the disadvantage is that this invention can not clean the insulator string installed on the tower pole. If the insulator string is repaired daily, it still needs personnel to climb the tower pole and then rely on manpower to clean the insulator string. At the same time, it needs personnel to climb the tower pole before cleaning the insulator string. To check whether it is qualified, during the process, people climbing the tower may cause the risk of falling or electric shock.
