Embodiment Construction
[0013] The deicing agent is conveyed into the metal pipe in the tower by the ground conveying pump, and a relay station is set every 20m according to the height of the tower, and is conveyed to the top of the tower in a stepwise manner, and then the top conveying pump pumps the deicing agent from the rotating pipe joint into the rotating blade In the metal pipe, it is connected to the inlet of the water outlet device through a hose. The water outlet device is designed as a valve body. By changing the output power of the water pump at the top of the tower, the inlet pressure of the water outlet device is controlled. When the liquid on the lower surface of the T-shaped guide rod is greater than that on the upper surface Under surface pressure, the deicing agent liquid will push away the T-shaped guide rod, and the liquid in the cabin where the upper surface of the T-shaped guide rod is located will flow into the return pipe through the top outlet. Due to the trapezoidal design of ...

The invention relates to a wind turbine blade surface deicing device. The wind turbine blade surface deicing device is characterized in that the wind turbine blade surface deicing device comprises conveying pumps, relay stations, a conveying pipe, a rotary pipe joint, a conveying metal pipe, blade inner fixing supports, a linkage hose and a blade surface water outlet structure, wherein a deicing agent is conveyed by a chain of the conveying pumps to the top end of a wind turbine tower in a multi-stage mode through the relay station; the conveying metal pipe is fixed inside the blades through the fixing supports; and the closing of an outlet is controlled by the water outlet structure through inlet pressure and a top spring. The deicing agent is conveyed through small holes in the surfacesof the blades, ice layers are melted from the inside of an icing area, therefore, the deicing can be more convenient and fast, the normal work of a wind turbine is not influenced in the deicing process, and the deicing work efficiency is improved.
Description
