Abstract
A blade support limb structure of a vertical axis wind power generator includes a fixed support limb () and a rotatable support limb (), one end () of the rotatable support limb is connected with one end () of the fixed support limb and the rotatable support limb may rotate around it. The structure keeps a wind wheel at stable rotation speed in the case the environmental wind speed exceeds the rated wind speed, thereby to ensure that vertical axis wind power generator outputs constant power. The structure solves a problem of constant power output of the vertical axis wind power generator from hundreds watts to thousands watts, so its applications are wide.
