Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a vertical axis wind power generation device. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. A wind turbine generally consists of components such as a wind wheel, a generator, a direction regulator, a tower, a speed limit safety mechanism and an energy storage device. The working principle of a wind turbine is relatively simple. The wind wheel rotates under the action of wind force, and it converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. The generator rotates and generates electricity driven by the wind wheel shaft.

[0003] In actual use of the existing vertical axis wind turbines, when encountering strong winds, the blades will be subjected to strong wind force. Most of the blades of the current vertical axis wind turbines do not have a reinforcement structure, which will cause the blades to deform or be damaged when subjected to strong wind force. This not only greatly reduces the service life of the blades, but also greatly reduces the power generation efficiency of the wind turbine. To this end, we propose a vertical axis wind turbine to solve the above problems. Utility Model Content
