Vertical shaft integrated horizontal self-varied propeller-type wind power generation device

Abstract

The invention discloses a vertical shaft integrated horizontal self-varied propeller-type wind power generation device. The device comprises a generator; the generator is connected with a main shaft arranged vertically through a speed changer. A plurality of paddle components are horizontally arranged on the excircle of the main shaft along axial direction; each paddle component comprises a shaftsleeve horizontally arranged on the excircle of the main shaft; a rotating shaft of the paddle is arranged in the shaft sleeve; the two ends of the rotating shaft of the paddle are respectively provided with paddles the paddle surfaces of which are vertical with each other; a clamping pin is mounted on the excircle of the rotating shaft of the paddle in a radial direction; a limited groove the width of which is one fourth of circumference of the shaft sleeve is arranged on the inner wall of the shaft sleeve; the clamping pin is arranged in the limited groove along the width direction of the limited groove in a swinging manner. The device of the invention has reasonable design, novel structure, high rotating speed, and great moment of rotation, and can drive generators with high power to work. As the paddle rotates horizontally, and the windage generated by the rotation of the paddle is small, so that high-speed rotation of the paddle can be realized in big wind.

Description

technical field [0001] The invention relates to a wind power generation device, in particular to a vertical axis integrated horizontal self-variable pitch wind power generation device. Background technique [0002] At present, countries around the world are increasingly demanding energy, especially when traditional resources such as coal and oil are increasingly depleted and traditional energy sources are increasingly polluting the atmosphere. People are increasingly researching and utilizing clean and renewable energy. increasingly urgent and widespread. As a clean and renewable resource, wind energy has become an important subject of research by scientists from all over the world. At present, most wind energy conversion systems use horizontal-axis wind turbines, that is, three blades are installed on the horizontal axis. This structure is relatively simple, the investment is relatively small, and the technology is relatively mature. 3m / s) to generate electricity. Howeve...
