Abstract

The invention provides a wind driven generator rotor blade with electrothermal deicing devices. The wind driven generator rotor blade comprises a blade body, wherein the blade body comprises an inner surface and an outer surface; the inner surface of the blade body encircles a cavity body of the blade body; and the electrothermal deicing devices for converting electric energy into heat energy to melt ice on the blade body are arranged on the outer surface, the inner surface and / or an interlayer structure of the blade body. The wind driven generator rotor blade can melt the ice on line in a normal power generation state of a wind driven generator, so that the working efficiency of a wind driven generator set is improved, and the power generation amount is increased; and the blade cannot be attacked by outer force. Meanwhile, the wind driven generator rotor blade has the characteristics of power saving, light weight, flexibility in shape and mounting and the like.

Description

technical field [0001] The invention relates to a structure for preventing the freezing of outdoor power equipment, in particular to an electric heating ice-melting device capable of preventing the rotor blades of a wind power generator from freezing, and belongs to the technical field of wind power generation equipment. Background technique [0002] With the shortage of energy and the deterioration of the ecological environment, the application of wind power at home and abroad is becoming more and more extensive. However, in recent years, extreme weather disasters have occurred frequently, especially the increase in freezing rain in my country, which has seriously affected the operation of wind power generation. In the climate of freezing rain, the rotor blades of the motor are prone to ice formation, which will cause the following hazards to wind power generation: On the one hand, as the ice layer thickens, the physical shape of the blades will change, reducing the wind-re...
