Problems solved by technology

The turbine type has good adaptability to the environment with low air density, but its structure is complex, difficult to manufacture, and high in cost
[0005] Most of the existing vertical-axis wind turbines use the lift-type wind turbine represented by the H type. The H-type wind turbine with a fixed impeller radius has no adjustment effect on the rotation speed of the wind rotor due to its single fixed support rod. , the stability under strong wind conditions cannot be guaranteed

Abstract

The invention discloses a vertical axis wind turbine applicable to the typhon. The vertical axis wind turbine comprises a traditional base, a stand column, a power generator and the like. On this basis, a centrifugal ball driving device and a telescopic rod connecting rod mechanism are added. When the vertical axis wind turbine operates under the condition of strong wind, blades of the vertical axis wind turbine can automatically retract to the stand column. The radius of an impeller is reduced, and the output power is reduced accordingly. The vertical axis wind turbine can transit between high wind speed and high wind speed, and accordingly, the radius of the impeller changes continuously. The vertical axis wind turbine can well adapt to the environment with coexistence of low wind speedand high strong wind.

Description

technical field [0001] The invention relates to a vertical axis wind power generator. Background technique [0002] As the energy crisis continues to deepen, wind energy, as a renewable clean energy, has attracted widespread attention. Wind energy has unique advantages such as huge reserves and wide distribution. The main form of wind energy utilization is to use wind turbines to generate electricity. The core component of a wind turbine is the wind rotor, and the blade technology of the wind rotor directly affects the energy efficiency of the wind turbine. [0003] Compared with horizontal axis wind turbines, vertical axis wind turbines have the advantages of no need to face the wind, good safety, low noise, high wind energy capacity per unit area, and wide application range. In terms of construction, it has broad application prospects. Through continuous development, the role of vertical axis wind turbines has become more and more obvious. [0004] There are various fo...
