Abstract

The invention relates to a novel vertical shaft windmill device, which consists of a vertical shaft, a vane rack, vanes, a guide rail, a pinion-and-rack mechanism and so on. Through control of vane corners, the vanes are guaranteed to be able to always bear the wind thrust in a semicircle with wide area; moreover, the wind thrust is reduced in the other semicircle with a narrow streamline body, thereby the vanes not only can generate the driving force which drives the vertical shaft to rotate under the action of wind and rotate around the vertical shaft but also can rotate around axial lines of the vanes according to stress requirements. Under the condition of reasonable distribution of the vanes (for example, uniform distribution of three pairs or four pairs), the thrust difference can be generated under the action of certain wind speed so as to form the operation torque which directly drives the vertical shaft to rotate. A service machine can be driven without the necessity for changing the direction of torque output of the device, and the efficiency of a windmill can be effectively improved, thereby being simple and practical.

Description

technical field

[0001] The patented technology belongs to the field of mechatronics, involves wind power utilization technology, and can use wind power, a renewable energy in nature, to generate electricity for human beings, lift water for irrigation, and drive various rotary working machines. Background technique

[0002] With the development of society and economy, energy is becoming more and more scarce. Wind power, as a renewable energy that does not pollute the environment, has been paid more and more attention to and widely used in power generation and other fields. At present, most of the more mature wind turbines are horizontal shafts. Due to the influence of the environment, their power is often converted into a vertical shaft through the mechanism to drive the working machine, which makes the mechanism complicated, energy consumption, cost increase, and installation difficult. The utilization rate of wind energy is reduced, and its application range is limited. C...
