Description

Wind power fan with multiple sets of wind rotors

technical field

The utility model relates to a wind power generator with multiple sets of wind wheels. the

Background technique

Wind turbines use wind power to drive blades to rotate to drive generators to generate electricity. Wind power is becoming a craze around the world because it has no fuel issues and doesn't produce radiation or air pollution. The wind turbine mainly has three parts: the wind rotor, the nacelle and the tower. The wind rotor is installed on the vertical tubular tower. Existing wind power generators can be divided into horizontal axis type and vertical axis type. When the horizontal-axis wind power fan works, the direction of the rotating shaft is consistent with the wind direction, and when the vertical-axis wind power fan works, the direction of the rotating shaft is at right angles to the wind direction. Horizontal axis wind turbines usually need to constantly change direction to keep in line with the wind direction, but vertical axis wind turbines do not have to, because it can harvest wind energy from different directions. the

At present, the common wind turbines are generally three-bladed wind rotors, whose windward side cannot be adjusted in size, and are easily damaged in typhoon-prone areas. the
