Problems solved by technology

[0002] When wind turbines operate in cold climates, the surface of the blades of the wind turbines usually has serious ice coating in winter, and the aerodynamic shape of the blades changes significantly after icing, which will seriously affect the aerodynamic efficiency of the blades and reduce the power generation efficiency of the wind turbine. After icing, the load of the unit and the blades will also increase. When the loads and mass moments of the three blades differ to a certain extent, it will usually cause the vibration of the unit, thus affecting the safe and stable operation of the unit.

Usually, for the safe operation of the unit, the unit will stop running after the blades are covered with ice, so the icing of wind turbine blades will lead to serious loss of power generation

[0003] In order to solve the problem of icing on the surface of the blade, there are mainly deicing methods such as spraying superhydrophobic anti-icing coating on the surface of the blade, heating with hot air, heating the surface of the blade with carbon fiber cloth, and covering the surface of the blade with a carbon crystal heating film. Deicing technology generally has the following problems: 1. The heating effect is not stable and reliable; 2. The external shape of the blade is greatly affected due to the heating mechanism; 3. The processing and manufacturing process of the blade is relatively complicated, the production cost is high and the production efficiency is not high.
