Embodiment 1

[0050] Reference attached figure 1 -Attached Figure 4 As shown, in the deicing device of this embodiment, the control module is connected to the external power supply through the power supply module. During deicing work, the control module 4 turns on the heating module 2, and the warm body radiation heating film 21 in the heating module 2 can be adjusted according to the blade 5 The temperature of the inner surface automatically adjusts the output power of the radiant heating element 213 to stabilize the temperature near the preset target temperature without regulation by the control module 4 , thereby avoiding damage and aging caused by local overheating of the blade 5 .

[0051] First, the power supply module 1 provides power for the device, and the voltage range of the power supply module 1 is 220V-690V to supply the control module 4 with a suitable working voltage of 690V, which is adapted to the voltage of the wind turbine. The heating module 2 and the control module 4 ...

Embodiment 2

[0055] At the same position on the inner surface of the blade 5, a warm body radiation heating film 21 with multiple layers of non-reflection layers 214 can be laid, and then the multi-layer warm body radiation heating films are connected in parallel, and then the reflective layer 214 is uniformly installed and connected to the control module 4 to enhance the warm body radiation. Radiant heating effect of the thermal film 21 .

[0056] It can be seen from the implementation that the present invention can be used to realize automatic temperature control of any local position in the process of heating and deicing wind turbine blades, avoid blade damage and aging caused by local overheating, improve the energy efficiency of deicing, and reduce the cost of the device. complexity, reducing installation costs.

Description

technical field [0001] The invention relates to a blade deicing device in the technical field of wind power generation, in particular to a wind turbine blade deicing device for realizing self-controlling temperature. Background technique [0002] At present, the mature and large-scale application of anti-icing and de-icing technologies for wind turbine blades in the world is mainly to prevent the wind turbine blades from freezing or to remove ice that has adhered to the blades by heating the wind turbine blades. The heating methods of wind turbine blades mainly include electric heating method and gas heating method. The electric heating method is to lay a layered electric heating material on the outer surface of the wind turbine blade shell or in the shell layer under the blade skin, and generate thermal energy through the electric heating material, and conduct it to the surface of the blade and the ice or water attached to the surface, so as to achieve deicing. anti-icing ...
