The invention discloses a deicing device and method for a blade of a wind turbine generator. The device comprises a plurality of spray pipes arranged on a tower drum at intervals up and down, whereinhorizontal length of each spray pipe is smaller than distance between the blade and the tower drum, all the spray pipes are connected with a hydraulic pressure station through delivery pipes, the hydraulic pressure station comprises a liquid storage tank and a hydraulic pump, an ice melting agent is stored in the liquid storage tank, the hydraulic pressure station is connected with a deicing control system, and the deicing control system is connected with a wind turbine generator control system. The deicing device has the beneficial effects of being simple in structure, low in manufacturing cost, high in deicing efficiency and low in safety risk and the deicing process is highly repeatable.
Description
technical field [0001] The present invention relates to the technical field of blade deicing, in particular to a wind turbine blade deicing device and method. Background technique [0002] Icing of blades of wind turbines will lead to reduced or zero output capacity. Currently, there are five types of deicing and anti-icing methods for blades in the market: [0003] 1) Lay (clamp) additional thermal elements in the blade body. [0004] Its working principle is to embed the electric heating element into the blade and cover the area that affects the aerodynamic performance of the blade. When the blade freezes, the electric heating element will increase the surface temperature of the blade and form a water film between the ice accretion layer and the blade surface. The ice is thrown out by centrifugal force, or the electric heating element is activated when the blade is about to freeze to prevent or alleviate the blade from icing, so as to achieve the effect of deicing (anti-i...
