Background The insulator is used as a core insulating component in a power transmission and transformation circuit of a power system, and the surface cleanliness of the insulator is directly related to safe and stable operation of a power grid. The insulator umbrella skirt is easy to attach pollutants such as dust, greasy dirt and salt fog crystals after long-term exposure in an outdoor environment, if the insulator umbrella skirt is not cleaned effectively in time, the surface insulation performance is reduced, faults such as flashover and pollution flashover are caused, and even large-area power failure is caused when the faults are serious, so that huge loss is brought to the operation and maintenance of a power system. Therefore, the insulator cleaning is a key and necessary link for ensuring the safe and stable operation of the power system, and the cleaning effect and the operation reliability of the insulator cleaning have important influence on the operation and maintenance quality of the power grid. However, there are still a number of short plates that need to be addressed in the current mainstream insulator cleaning technology. In the prior art, the bristle brush with fixed length is difficult to penetrate into a gap in the deep part of the umbrella skirt, and the cleaning strength of the soft bristle brush is insufficient. Although the electric telescopic brush proposed in recent years can solve the profiling problem, the electric telescopic brush requires a complex sensor, a controller and a large number of micro motors, has high cost and extremely high failure rate under the environment with water and high voltage. In addition, the existing insulator cleaning brush is not thorough in cleaning due to uniform bristle length and incapability of adapting to concave-convex structures between umbrella skirts, and the existing electric telescopic scheme is complex in structure and difficult to realize self-adaptive cleaning. Therefore, there is a need to design a cleaning device that is simple in structure and can automatically adapt to the concave-convex shape of an insulator without electronic control.

Further, in order to achieve overlapping of the cleaning coverage areas, the arrangement intervals of the self-adaptive hairbrush groups correspond to the axial intervals of the umbrella skirts of the insulators to be cleaned, and the adjacent composite hairbrush units are staggered in the circumferential direction. Further, in order to ensure that the brush bundles flexibly work when the umbrella skirt is in contact with the protrusions, the flexible supporting cores are used for contacting the surfaces of the insulators and transmitting reverse thrust force to force the sliding blocks to retract against centrifugal force, the technical problem that pure soft hair cannot effectively push the mechanical structure to retract is solved, the self-adaptive brush group is composed of a plurality of composite brush units which are respectively arranged in corresponding guide slide ways, each composite brush unit comprises a brush bundle arranged in each guide slide way, the center o
