Abstract

A vertical shaft wind turbine belongs to the field of wind power generation, and solves the problems that the vertical shaft wind turbine has lower wind energy utilization rate, complicated structure, higher production cost, and the like. The vertical shaft wind turbine includes a box support seat assembly, a vertical shaft assembly, a blade assembly and screws, wherein the box support seat assembly consists of a gear box, a combined bearing with steel balls in round holes, a bearing seat, a radial bearing and a bearing end cap; the vertical shaft assembly consists of a pin fixed transmission shaft and a blade mounting shaft that are connected together; and the blade assembly consists of a torsional spring, a horizontal shaft, a spacing screw, a shaft sleeve, a bearing, a bearing end cap, an adjusting screw, a fastening screw, a connecting piece and a blade board. According to the vertical shaft wind turbine, when no wind is blown in, the blade board has a dip angle, and when wind is blown in, the blade board swings around the horizontal shaft with one side of the vertical shaft swinging toward the horizontal direction and the other side swinging toward the vertical direction under the action of the wind force, and as the wind collecting areas on the two sides of the vertical shaft are different, torque is produced, and the horizontal shaft rotates around the vertical shaft, so as to output power.

Description

technical field [0001] The invention belongs to the field of wind power generation. It specifically relates to a vertical axis wind turbine (wind wheel) that converts wind kinetic energy into rotational mechanical energy. Background technique [0002] At present, the common wind turbines have a horizontal axis, while the existing vertical axis wind turbines mostly have blades arranged vertically and rotate around the vertical axis; many vertical axis wind turbines have low wind energy utilization, complex structures, and high manufacturing costs. Contents of the invention [0003] In the wind turbine provided by the present invention, the blades swing around a horizontal axis under the action of wind force, wherein one side of the vertical axis swings in the horizontal direction, and the other side swings in the vertical direction, and the wind collecting area of ​​the blades on both sides of the vertical axis is Different, and then generate torque, so that the horizontal...
