This invention relates to the field of wind power generation technology, and more particularly to a self-righting wind power generation device. It includes a wind-direction rotating support, a wind-resistant tilting adjustment component, and a wind power generation component. The wind-direction rotating support has legs on both sides of one end of its support column. A second support rod is installed between the top of the support column and the wind power generation component to achieve rotation in the direction of maximum wind power, thereby maximizing wind resistance and improving power generation efficiency. The wind-resistant tilting adjustment component consists of a telescopic mechanism. The stronger the wind, the greater the pressure, causing the support rod to shorten and tilt, reducing the overall height of the wind power generation component and decreasing the windward area, thus preventing wind damage. Conversely, when the wind power decreases, the pressure decreases, and the support rod extends, placing the entire wind power generation component at its highest position, maximizing the windward area and maximizing wind power generation. The wind power generation component consists of wind turbine blades and a generator, achieving highly efficient wind power generation.
