[0003] At present, most vertical-axis wind turbines use braking devices to stop the blades, which will inevitably cause waste of wind energy or delay the normal power generation time. Vertical-axis wind turbines use less and more complicated speed-stabilizing mechanisms. , the Chinese Patent Publication No. CN2036586U discloses a speed-stabilizing device for a wind-driven generator impeller group. The control accuracy of the blade windward angle is not high

The invention relates to an automatic speed stabilizing device of a vertical axis wind turbine. The automatic speed stabilizing device comprises an electric generator spindle and a plurality of wind blades. The wind blades are connected with the electric generator spindle through connection rods. Auxiliary blades are arranged on one sides of the wind blades correspondingly and adjust the angles formed by the auxiliary blades and the wind blades through automatic speed stabilizing mechanisms correspondingly. The automatic speed stabilizing mechanisms comprise rotary shafts and sliding blocks. The rotary shafts are connected with the auxiliary blades correspondingly. The sliding blocks are located in the connection rods correspondingly and can slide freely. A compressed spring and a pulley are fixed to the two ends of the inner wall of each connection rod correspondingly. One end of each sliding block is fixedly connected with the corresponding compressed spring. The other end of each sliding block is connected with one end of the corresponding rotary shaft in the mode that a rope-shaped component penetrates through the corresponding pulley. The automatic speed stabilizing device is simple in structure, and control over the rotation speed of an impeller is accurate.
Description
technical field [0001] The invention relates to a vertical axis wind power generator, in particular to an automatic speed stabilization device for a vertical axis wind power generator. Background technique [0002] The vertical axis wind turbine does not need to face the wind when the wind direction changes, which is a big advantage compared with the horizontal axis wind turbine. It not only simplifies the structural design, but also reduces the gyro force when the wind rotor faces the wind. In the field of wind power generation, wind turbines have an allowable maximum wind speed. When the maximum allowable wind speed is exceeded, the speed of the fan will exceed the rated speed and cause speeding. For this reason, when the wind turbine operates under strong wind conditions, the speed of the fan must be controlled. within the allowed range. There are two control methods for vertical wind turbines operating under strong wind conditions, one is the braking method, that is, th...
