Problems solved by technology

However, at present, no matter the vertical axis wind turbines of resistance type or lift type generally have the following defects: the starting torque is small, the structure is complicated, and when the wind is strong, the frontal area of ​​the wind rotor and the force are large, so that the output power of the generator is too high. Large, it is easy to cause the motor to exceed the rated generating power and be damaged
However, the vertical flexible wind wheel is difficult to ensure the overall stability of the vertical generator, and the vibration is large, and the ability to resist strong winds needs to be further improved, and the problem of narrow applicable wind speed range also needs to be further solved

Abstract

The invention discloses a wing variable pitch type vertical shaft wind generating set. A hinge device and a spring device are arranged between each fan blade unit and a corresponding rotary sleeve spindle, the fan blade units and the rotary sleeve spindles can rotate vertically and relatively through the hinge devices, when strong wind comes, the fan blade units lift and rotate to be under the suspension and fast turning state along with the increasing of the rotation speed of wind wheels, the stability is better, the stability of the wing variable pitch type vertical shaft wind generating set is not affected by the increasing of the wind speed, the output power is stable, and the service life of an electric generator is prolonged. The spring devices are arranged on the rotary sleeve spindles and located below the hinge devices and can assist in adjusting the included angle between supporting rods and the horizontal plane, and fan blades are stressed evenly when a wind wheel set rotates at a high speed. Each fan blade unit comprises fan blades, connection rods and two or more supporting rods which are parallel, wherein one ends of the supporting rods are fixedly connected with the connection rods, and the other ends of the supporting rods are hinged to the fan blades. When the fan blades are pushed to rotate by the wind power, the fan blades rotate relative to the supporting rods, the output power is adjusted, and the output power is stable.

Description

Technical field [0001] The present invention involves the field of vertical axis wind turbine technology, especially involving a wing -like vertical vertical axis wind turbine. Background technique [0002] In existing technologies, vertical axis wind turbines are mainly divided into two types: resistance and lift.The resistance vertical axis wind turbine mainly uses the resistance difference generated by the air flowing through the blades as a driving force, while the lift type uses the lift generated by the air flowing through the blades as the driving force.During the rotation process of the blades, as the speed increases the resistance, the lift will increase, so the efficiency of the lift -type vertical axis wind turbine is much higher than the resistance type.However, at present, regardless of the resistance type or lift -type vertical axis wind turbine, the following defects are generally existed: small starting torque, complex structure, and high wind wheels when wind whe...
