Technical Field

[0001] The utility model relates to the technical field of deicing devices, in particular to a blade deicing device for a wind turbine. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. A wind turbine generally consists of components such as a wind wheel, a generator, a direction regulator, a tower, a speed limit safety mechanism and an energy storage device. The working principle of a wind turbine is relatively simple. The wind wheel rotates under the action of wind force, and it converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates and generates electricity driven by the wind wheel shaft. Most wind turbines are installed outdoors, and severe weather often occurs in the outdoor environment. In rainy and snowy days, ice will appear on the blades of the wind turbine, resulting in an increase in the torque of the blade rotation, an increase in the load of the wind turbine set, and a decrease in the power generation efficiency. It is necessary to use an electric heating material de-icing device arranged inside the blades.

[0003] The existing wind turbine blade deicing device is prone to the following problems during use. First, the wind turbine blade deicing device uses electric heating materials arranged inside the fan blades to remove ice, but this deicing method takes a long time, consumes a lot of energy, and has a poor deicing effect. Second, the existing device does not take into account the impact on the blades during the deicing process. The blade surface is easily damaged during the deicing process, and new blades need to be replaced, which increases the investment cost and reduces the service life of the blades. Therefore, in response to the above problems, we propose a wind turbine blade deicing device. Utility Model Content
