Abstract

This utility model relates to a wind-driven cleaning device for column insulators, comprising a rotating mechanism, several fan blade assemblies, and a brush assembly. The rotating mechanism includes an inner cover and an outer cover. The inner cover is fixedly sleeved on the end of the insulating column of the column insulator. The outer cover is rotatably sleeved outside the inner cover and connected to the inner cover via a bearing. Several fan blade assemblies are circumferentially spaced on the outer wall of the outer cover. Each fan blade assembly includes fan blades, which are fixed to the outer wall of the outer cover and arranged at a certain angle. The brush assembly includes a brush rod and brush bristles. One end of the brush rod is fixedly connected to the outer wall of the outer cover, and the other end extends to the outside of the insulating disc of the column insulator. The brush bristles are fixed at the end of the brush rod away from the outer cover and are embedded between the multiple insulating discs. This device uses natural wind power as its driving force, consumes no additional electricity, achieves green cleaning, is energy-saving and environmentally friendly, and eliminates the need for manual labor, saving a significant amount of manpower, reducing cleaning costs, and also reducing safety hazards.
