Abstract

The invention provides a self-adaption variation paddle vertical shaft wind driven generator with blades provided with flaps. Due to the fact that a self-adaption variation paddle vertical shaft wind power driving device with the blades provided with the flaps is adopted, the involved vertical shaft wind driven generator is characterized by comprising a rotating unit and an adjusting unit; the adjusting unit is arranged below a supporting frame assembly of the rotating unit and comprises a track groove, a sliding block and a crank; the sliding block slides in the track groove and drives the crank to rotate through guiding of the groove; and the crank drives the blade flaps to automatically deflect by a certain angle, and thus the actual attack angles of the blades can be actively changed. Therefore, the self-adaption variation paddle vertical shaft wind power driving device with the blades provided with the flaps has the characteristics that the stalling property and the pneumatic performance of the blades are improved, and the wind energy utilization rate is increased.

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...
