Cyclone resisting vertical shaft wind motor based on vane corner control

Abstract

An anti-storm vertical-shaft wind turbine which is based on a blade angle control comprises a vertical shaft, a blade frame, a gravity pendulum mechanism, blades, a double-layer cam, a gear, a rack mechanism and so on, wherein the blades are evenly distributed on a circumference in three pairs. When wind speeds are different, the blade angle is controlled separately through the different guides ofthe double-layer cam; when the wind speed is normal, the blades are made to always bear the thrust force of the wind with a broad size in one semicircle and to reduce the thrust force of the wind with a narrow streamlined body in the other semicircle and under the blowing of the wind, the blades can produce an inertia which drives the vertical shaft to rotate; when the wind speed exceeds the normal working wind speed, owing to the rack mechanism enhancing and changing the functional cam guide, the blades are made to face the wind with the narrow streamlined body in the two semicircles and toreduce the effect of big wind, which protects the safety of equipment. The wind turbine can make use of the wind force to drive every kind of machine to generate power, pump, irrigate and so on with the safety, the efficiency and the practicality.

Description

technical field [0001] This patented technology belongs to the field of mechatronics and involves new energy technologies utilizing wind power. Its products can be widely used in natural renewable energy—wind power drives various machines for power generation, water pumping and irrigation. Background technique [0002] The development of social economy requires more and more energy, and mineral energy is becoming more and more scarce. Wind power, as a renewable energy that does not pollute the environment, has received increasing attention and has been widely used in the fields of power generation, water pumping and irrigation. At present, most of the more mature wind turbines are horizontal axes, which are usually bulky, and the installation space is affected by the environment, and their power is often converted into a vertical axis by a mechanism before it can be used to drive the working machine. When the wind force exceeds the normal wind speed, such as a particularly s...

AI Technical Summary

Problems solved by technology

In order to solve these problems, the wind turbine mechanism of the horizontal axis is complicated, the energy is wasted, the cost is increased, and the installation is difficult, which reduces the utilization rate of wind energy, is not conducive to safe production, and limits its application range

In order to overcome the deficiencies of the horizontal-axis wind turbine, the designer of this patent proposed a vertical-axis wind turbine that uses guide rails to control the blade rotation angle in the patent application for "a new type of vertical-axis wind turbine device" (application number 200810070949.3), which can overcome the above-mentioned dynamics Problems to convert to vertical axis and make installation easy, but not against wind hazard
