Description

Technical field

[0001] The invention relates to the technical field of wind power generation equipment, in particular to a small and medium-sized multi-stage vertical axis wind power generator. Background technique

[0002] At present, horizontal wind turbines are the most widely used in wind power generation. For vertical axis wind turbines, the application of small, medium and large generators is not particularly ideal. However, horizontal wind turbines are inherently noisy. , Large occupied area, difficult high-altitude maintenance, short service life, etc., need tail and yaw system to drive the blade, the structure is more complicated and other shortcomings, compared with the vertical multi-stage wind turbine, no need to face the wind, no noise, higher safety In terms of characteristics, it has a great advantage.

[0003] The blades of horizontal-axis wind turbines are subjected to the combined action of inertial force and gravity during one rotation. The direction of inertial...
