Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine units, in particular to an automatic ice removing device for wind turbine blades. Background Art

[0002] A wind power generation set is a system that converts the kinetic energy of wind into electrical energy.

[0003] In the wind power generation system industry, wind turbines play a crucial role in power supply in some regions. Therefore, regular maintenance of wind turbines is an important work item for power workers. In order to better obtain wind supply, the blades of wind turbine units are in a relatively high position for a long time to obtain wind energy supply. However, being in a high position for a long time, the temperature will decrease, resulting in a thick layer of ice on the surface of the wind turbine blades. This phenomenon is more common in cold weather. Due to the ice on the surface, the self-weight of the blades increases, making it more difficult for the wind to rotate, and thus affecting the power supply in people's daily lives.

[0004] Therefore, we provide an automatic ice removing device for wind turbine blades. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an automatic ice removing device for wind turbine blades to achieve the effect of automatically removing ice from wind turbine blades in view of the above existing technical problems.

[0013] Compared with the prior art, the present utility model provides an automatic ice removal device for wind turbine blades, which has the following beneficial effects:

[0014] 1. In the present utility model, when it is necessary to remove ice from the wind turbine blades in cold weather with a decreasing ambient temperature, the operator sends an electrical signal through the control cabinet inside the nacelle. The electrical signal is conducted through the electrical connection sleeve installed at one end to the inside of the pressurization chamber. The pressurization chamber starts to work, and the stored deicing agent liquid inside is pressurized and extracted outward through the transmission pipe. During the extraction and transportation process, the sealing pipe can ensure the sealing of the pipe body transportation and prevent leakage. After passing through the transmission pipe, the deicing agent liquid is evenly sprayed onto the surface of the fan blades installed on one side through the deicing spray head. The deicing agent liquid dissolves the ice layer covering the surface to achieve the effect of automatic ice removal.

[0015] 2. In the present utility model, through the set control cabinet, the effect of electrical control can be achieved.

[0016] 3. In the present utility model, through the mounting brackets installed inside the nacelle, an electromagnetic power generation device can be installed at the middle gap between the two mounting brackets. When the fan blades drive the rotating shaft to rotate through the wind force, the stator installed on the surface of the rotating shaft will rotate.

Through the electromagnetic windings arranged on the surface of the iron core, the conduction of the electromagnetic direction of the magnetic force lines is carried out, thereby achieving the conversion of wind energy into electrical energy.
