An anti-icing and noise-reducing wind power blade

Abstract

The invention relates to an anti-icing noise-reducing wind power blade. According to the anti-icing noise-reducing wind power blade, heat conducting pipes are arranged inside a shell, and rubber strips are arranged on the side of the shell in a densely-distributed mode. Heat conducting liquid and heating wires are arranged inside the heat conducting pipes. The heat inside the blade can be uniformly and stably distributed for a long time through the cooperation of the heat conducting liquid and the heating wires. Due to the setting of the shapes of the heat conducting pipes, uniform distribution of the heat of the heat conducting liquid can be kept in the blade rotating process. Due to the setting of the form of rubber strip noise-reducing components on the surface of the blade, the effectof supplementing the heat for the blade can be achieved when noise reduction is achieved, and the effective supplement of heat supply of the inside heat conducting liquid is achieved.

Description

technical field [0001] The invention relates to the field of wind power generation, and specifically relates to an anti-icing and noise-reducing wind power blade. Background technique [0002] Wind power is being used more and more widely as a clean energy source. Wind farms are generally located in relatively less populated desert areas or sea areas. Although such areas are generally rich in wind resources, their annual temperatures are relatively low. , so after setting up wind turbines in this type of area, since the wind turbine blades are set at a relatively high position and receive the impact of wind for a long time, the phenomenon of icing of wind turbine blades is very common, and the phenomenon of icing is also harmful to wind turbine blades. The normal work has a greater impact. There are also anti-icing wind turbine blades in the prior art. The most common way is to heat the blades as a whole by passing hot air. However, due to the relatively low specific heat o...

[0002] Wind power is being used more and more widely as a clean energy source. Wind farms are generally located in relatively less populated desert areas or sea areas. Although such areas are generally rich in wind resources, their annual temperatures are relatively low. , so after setting up wind turbines in this type of area, since the wind turbine blades are set at a relatively high position and receive the impact of wind for a long time, the phenomenon of icing of wind turbine blades is very common, and the phenomenon of icing is also harmful to wind turbine blades. the normal work of the

There are also anti-icing wind turbine blades in the prior art. The most common way is to heat the blades as a whole by passing hot air. However, due to the relatively low specific heat of hot air, it is necessary to pass in a large amount of hot air at a high temperature to achieve deicing. Relatively low deicing efficiency

Similarly, there is also a method of building a heating wire in the blade, but the heating wire is directly built into the blade, and the heating medium is directly the blade, and there is no insulation measure, so the heating effect is not very ideal.
