Surface cleaning device of wind electricity blade

Abstract

The invention provides a surface cleaning device of a wind electricity blade. The surface cleaning device comprises a cleaning assembly, wherein sliding grooves are formed in the outer side of the cleaning assembly in the circumferential direction; each sliding rail is in sliding connection to the corresponding sliding groove; the sliding rails horizontally penetrate through the left tail end andthe right tail end of the wind electricity generating equipment blade; the sliding rails are fixedly connected with the blade through bolts; mounting discs are in threaded connection to the outer sideof the cleaning assembly; a clamping disk is welded to the tail ends of the mounting discs; a telescopic oil cylinder is welded to the outer sides of the mounting discs; an electromagnetic switch isarranged on the outer side of the telescopic oil cylinder, and is connected with a control terminal of a wind electricity generating equipment control chamber through a wire; the cleaning assembly comprises an annular supporting frame; an elastic cushion is connected to the inner side of the supporting frame in a clamping manner; a first brush ring, a second brush ring and a third brush ring are sequentially arranged on the inner side of the elastic cushion from left to right; and the burr hardness of the first brush ring, the burr hardness of the second brush ring and the burr hardness of thethird brush ring are sequentially reduced, and the burr density of the first brush ring, the burr density of the second brush ring and the burr density of the third brush ring are sequentially improved. The surface cleaning device disclosed by the invention has the beneficial effects that the speed and the quality of cleaning the surface of the blade can be notably improved, and the operation steps are simple.

Description

technical field [0001] The invention relates to the technical field of wind power equipment, in particular to a wind power blade surface cleaning device. Background technique [0002] With the gradual improvement of people's awareness of environmental protection, people pay more and more attention to clean energy such as wind energy, so the proportion of wind power equipment in the power field is increasing. With the increasing number of wind power equipment put into use, people gradually find that after long-term use of wind power equipment, a thick layer of dust will be deposited on the surface of wind power blades. The gravity of the dust becomes the resistance to the rotation of the blades, which will directly reduce the power generation efficiency of the wind power equipment. In addition, the accumulation of these dust and dirt will also increase the noise of blade rotation, which will cause noise pollution to the environment of the wind power generation area. In orde...
