The invention relates to an overhead cable anti-inclination skin cleaning device and belongs to the technical field of power equipment. The cleaning device comprises an inner cleaning cylinder and anouter driving cylinder arranged concentrically. The power line passes through the inner cleaning cylinder. The outer driving cylinder is equipped with a counterweight motor whose output end extends into the outer driving cylinder to drive driving gears and ring gears on an outer wall of the inner cleaning cylinder to be engaged to rotate, the inner cleaning cylinder drives cutters on outer circumference at two ends of the inner cleaning cylinder to rotate, and a cleaning unit of an external obstruction of the transmission line is formed. The rotation of the inner cleaning cylinder drives self-rotation gears at outer ends of the rotation shafts which pass through the wall thickness of the inner cleaning cylinder to run along guide gears on an inner wall of the outer driving cylinder, the self-rotation gears drive a shredder mechanism to crush adhering objects along the surface of the power line through the rotation shafts. The shredder mechanism comprises rotating shafts whose ends havecrushing cutters and floating net covers fixed to the ends by springs. According to the overhead cable anti-inclination skin cleaning device, the cleaning of surface adhering objects and external hanging objects and close objects of the transmission line can be realized, and the cleaning effect is good.
