Vane of stirring type wind power heating start device

Abstract

The invention relates to a vane of a stirring type wind power heating start device. The vane of the stirring type wind power heating start device is provided with a turbo type flat vane composed of four blades, wherein holes are punched in the four blades in the turbo type flat vane in staggered mode, and used for decreasing the sweeping area of the vane, enable the stirring type wind power heating start device to normally start under low wind speed, and prevent a wind curtailment phenomenon from occurring. The two holes respectively in each two adjacent blades of the four blades are staggered, wherein one hole is located in the tail of one blade, the other hole is located in the head of the other blade. The sweeping area of the novel vane is decreased, and therefore torque needed for starting a heater of the novel vane is reduced in a starting moment, the problem that large torque is needed in the starting process of the stirring type wind power heating start device is solved, and thestirring type wind power heating start device can normally start under the low wind speed. By punching the holes in the four blades in staggered mode, a heating working medium can be completely stirred, collision and friction frequency between the heating work medium and each stirring blade is increased, and therefore temperature of the working medium is increased, and heating effects are guaranteed.

Description

technical field [0001] The invention relates to a stirring type wind energy heating device, in particular to a blade of a stirring type wind energy heating starting device. Background technique [0002] Stirring wind energy heating is a green and efficient heat production method, which is highly respected because of its strong adaptability to wind conditions, small equipment investment and high heating efficiency. In the context of energy transition, the use of wind energy to stir and directly generate heat can not only reduce the phenomenon of wind abandonment and improve the utilization rate of wind energy, but also help to solve the problem of heating in winter in my country. [0003] The start-up process of the stirring wind energy heating device requires a large torque. However, under natural wind conditions, the low wind speed cannot drive the stirring heating device to start normally, and there are few studies on the starting performance of the stirring wind energy he...

Problems solved by technology

[0003] The start-up process of the stirring wind energy heating device requires a large torque. However, under natural wind conditions, the low wind speed cannot drive the stirring heating device to start normally, and there are few studies on the starting performance of the stirring wind energy heating device at home and abroad. This also limits the further development of stirring wind energy heating technology
