Abstract

The invention discloses a wind turbine blade ice preventing / removing device and a wind turbine blade. The device comprises a heating layer, a heat transfer layer and a packaging layer. The heating layer, the heat transfer layer and the packaging layer are sequentially arranged from inside to outside and serve as an independent outer whole to be attached to the front edge of the blade base body. The independent external shape is the same as the airfoil of the blade base body; the heat transfer layer is made of a graphene composite material woven structure; the heating layer is provided with a plurality of resistance wires; and the packaging layer is made of a glass fiber composite material. The heating unit, the heat transfer unit and the packaging unit are adopted in the device, the anti-icing / deicing heating efficiency of the wind turbine blade is improved, and the anti-icing / deicing efficiency and the energy utilization rate of the wind turbine blade are improved.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a graphene-based composite material in-service wind turbine blade anti-icing device. Background technique [0002] As a renewable energy, wind energy has abundant reserves, is easier to obtain and transform than traditional energy sources, and causes relatively less pollution to the environment. Therefore, wind power occupies an important position in the world's energy structure. [0003] As one of the key components of the wind turbine, the blade's structure and strength are crucial to the reliability of the wind turbine, and its performance will directly affect the stability of the wind turbine. With the increase of the meteorological environment envelope in the working environment of wind turbines, more and more wind turbine blades are facing the problem of icing on the surface. After the surface of wind turbine blades is icy, the ice layer changes t...
