Ultrasonic deicing device for blades of wind generating set

Abstract

The invention belongs to an ultrasonic deicing device for blades of a wind generating set. According to the ultrasonic deicing device, a device main body mainly comprises three parts, namely, an ultrasonic generating device body, a transmission device body and a walking device body; the ultrasonic generating device body mainly comprises an ultrasonic generator, the ultrasonic generator sends out ultrasonic wave signals, other media transmit force of ultrasonic waves, and therefore the effect of removing ice coating on the blades of the wind generating set is achieved; the transmission device body comprises a motor, a driving belt wheel, a driven belt wheel, a V belt, a driving shaft and fourteen guide wheels and is used for providing power and transmitting the power, and the guide wheels provide the effect of force for crawler belt walking and the walking power for supporting the walking device body; and the walking device body comprises a crawler belt and a suction cup and is used fordriving the device to crawl and reach a final tail vane of the wind generating set. The ultrasonic deicing device has the advantages of being simple in structure, stable in operation and capable of smoothly climbing onto a wind turbine for deicing.

Description

technical field [0001] The invention belongs to an ultrasonic deicing device, in particular to an ultrasonic deicing device for blades of a wind power generating set. Background technique [0002] When the wind turbine works in winter, due to the cold winter temperature, the blades of the generator are prone to frost and ice, which will affect its power generation efficiency. Because the velocity of air flowing through the blades is increasing, more and more ice will accumulate on the leading edge of the blades, so we have to find a way to solve the ice and fog on the blades so that the blades can work effectively. After the blades of the wind turbine freeze, the frequency of the blades will change and the efficiency will decrease. This will also increase the fatigue load of the fan, cause resonance, overload or damage the gearbox, and the steel will become brittle after freezing and cracks are more likely to appear , if there is an external impact, it will cause damage to ...
