Description

Technical Field

[0001] The utility model belongs to the technical field of wind power generation and relates to a wind power generator with an easily adjustable wind receiving angle. 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 a wind rotor, a generator (including devices), a direction regulator (tail wing), a tower, a speed limiting safety mechanism and an energy storage device. The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of wind force, and it converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft. The generator rotates and generates electricity driven by the wind rotor shaft.

[0003] However, in the existing vertical axis wind turbines, since the wind direction is constantly changing, the fixed wind turbine blades cannot always be aligned with the wind direction, which results in low power generation efficiency and inconvenience in use. Utility Model Content
