Problems solved by technology

Although the above-mentioned existing technologies all adopt different deicing equipment and methods to melt the blades, in actual use, power generation is often affected by icing, and the existing technologies cannot meet the needs of actual production. The problem of blade ice melting is already an obstacle to wind power production in winter, and new technologies are urgently needed to solve it

Embodiment Construction

[0063] See attached figure 1 , 2 .

[0064] A conventional wind generator blade is composed of a blade main beam 2 and a blade skin 5, and the blade main beam and blade skin 5 of the present invention are designed according to a conventional blade design method. In the present invention, a layer of heating layer 4 is provided outside the blade skin 5 to completely wrap the blade skin 5, an insulating layer 3 is arranged outside the heating layer 4 to completely wrap the heating layer 4, and a lightning protection layer 1 is arranged outside the insulating layer 3 to completely wrap it. Insulation layer 3, the lightning protection layer is connected with the lightning ground wire. The insulating layer completely wraps the heating layer, and the insulating layer adopts insulating material. The insulating material of this embodiment adopts glass fiber. The lightning protection layer is a metal mesh or metal sheet that completely wraps the insulating layer. The lightning prot...

Abstract

The invention discloses a transversely heated ice melting blade of wind turbine and a device and a method of melting. The blade of wind turbine is provided with a heating layer, an insulation layer and a lighting protection layer which the cover of blades. The heating layer is embedded in the heating material by the heating power wire. The heating layer adopts the method of radial conduction and the transverse heating. The heating layer consists of heating material and heating power wire on radial conduction. The heating layer consists of a transverse wire, a heating tape and an insulated tape on the transverse heating. The heating transverse tape and the insulated transverse tape distributes in interval. The heating transverse tape involves two kinds: the transverse banding and the transverse opened-window. The automatic melting device consists of a switching circuit, a microprocessor and a communication module. The microprocessor makes control for the switching circuit under the control of control center, and then drives procedure of microprocessor and the automatic ice melting subroutine to melt or finish melting. The transversely heated ice melting blade of wind turbine and a device and a method of melting can judge the blade whether freeze or not and the automatically melt in time to avoid turbine stopping working for freezing.

Description

[0001] (1) Technical field [0002] The invention belongs to the field of wind power generation, and relates to a laterally heated ice-melting blade of a wind power generator, an ice-melting device and an ice-melting method thereof. [0003] (2) Background technology [0004] At present, wind power generators are being popularized and applied on a large scale, but in winter, the blades of wind power generators may be shut down due to icing. Solving the problem of wind turbine blade ice melting can avoid the loss of wind power plant production caused by blade freezing shutdown. [0005] The Chinese patent "Blade Deicing Device and Wind Turbine, and Blade Deicing Method" with the application number CN201511019717.1 uses an air pump to inject gas into the coating to expand the blade when the blade needs to be deiced, and quickly completes the blade deicing. The Chinese patent "Ice Melting Heating Structure of Wind Turbine Blades and Its Manufacturing Method" with the application ...
