Abstract

The invention provides an adaptive pitch vertical axis wind turbine with blades equipped with flaps. The vertical axis wind turbine involved in the present invention adopts an adaptive pitch vertical axis wind drive device with blades and flaps, and is characterized in that it has a rotating unit and an adjusting unit, and the adjusting unit is arranged at the lower part of the support frame assembly of the rotating unit. , including a groove track, a slider and a crank. The slider slides in the groove track. Through the guidance of the groove, it drives the crank to rotate, and the crank drives the blade flap to automatically deflect to a certain angle, so it can actively change the actual angle of attack of the blade. . Therefore, the adaptive pitch vertical axis wind drive device with flaps on the blades has the characteristics of improving blade stall characteristics, improving blade aerodynamic performance and wind energy utilization.

Description

technical field [0001] The invention belongs to the field of wind power generation, and relates to a self-adaptive pitch-variable vertical-axis wind drive device with blades and flaps. Background technique [0002] China is rich in wind energy resources. Vigorously developing wind power generation is of great significance to adjusting energy structure, ensuring energy security, coping with climate change and promoting sustainable economic and social development. Among them, wind turbines, as key equipment for wind power generation, play an extremely important role in the development of wind power in my country. . However, the periodic change of the angle of attack of the vertical axis wind turbine makes the dynamic stall characteristics of the blades obvious, the aerodynamic performance of the wind turbine is affected, and the structural stability and energy harvesting efficiency need to be improved. [0003] When a wind turbine blade rotates, the actual angle of attack of t...
