Movable insulator cleaning device and cleaning method

Abstract

The invention discloses a movable insulator cleaning device and a cleaning method. The cleaning device comprises a moving trolley; the cleaning device further comprises a cleaning head, a moving module connected with the cleaning head and an electric control mechanism for controlling the cleaning head and the moving module; and the cleaning head comprises a brush head base, a cleaning brush installed on the brush head base, a transmission belt which drives the cleaning brush to rotate, a driving motor which is connected with the transmission belt, and distance measuring sensors evenly distributed on the upper surface of the brush head base and used for positioning the center position of an insulator. The movable insulator cleaning device is high in automation degree, high in adaptability and high in cleaning speed; the device can be remotely controlled to move to the side of the insulator and automatically align with the center of the insulator. The brush head can be adjusted in a multi-degree-of-freedom mode, so that insulators arranged at various inclination angles can be cleaned.

Description

technical field [0001] The invention relates to a cleaning device and a cleaning method, in particular to a mobile insulator cleaning device and a cleaning method. Background technique [0002] In converter stations and substations, when composite insulators are exposed to the outdoors for a long time, a large amount of dirt will adhere to the surface. Various particles such as dust in the air, industrial exhaust gas, industrial smoke, oil particles, etc. or bird droppings will accumulate on the outer surface of the insulator. The formation of a pollution layer will lead to the reduction of the surface insulation capacity of the insulator and the increase of the surface leakage current in the case of moisture, so that pollution flashover accidents will occur under normal voltage operation. Pollution flashover accidents have a great impact on the power system, and even cause the entire power grid to be paralyzed. Therefore, composite insulators must be cleaned or replaced in ...

AI Technical Summary

Problems solved by technology

Due to the elasticity of the composite insulator, it is in the form of stacking multiple umbrella pieces, and the umbrella pieces have inner arc and outer arc shape, so the cleaning of the insulator has the problem of low efficiency and poor effect

Patent CN 108480257 A adopts a ring mechanism with two brushes to scrub the insulator, but this device cannot be applied to inclined insulators or insulators of different diameters

The existing insulator cleaning devices have the problems of low cleaning efficiency, weak cleaning ability and poor adaptability
