Abstract

The invention discloses a wind power generation turbine with retractable blades. The wind power generation turbine comprises a wind rotor, an engine room, and a pole with a rotation shaft therein, wherein the wind rotor includes studs fixed on the top of the rotation shaft; a blade consisting of two retractable vanes opposite to each other is arranged on each support rod; a main support rod with an automatic opening-closing mechanism is arranged on the studs; the automatic opening-closing mechanism includes a sliding member and a limiting member capable of sliding along the main support rod, and a control device for driving the limiting member to slide; and a support rod is connected between the sliding member and the vanes in a rotary manner. When the control device drives the limiting member to slide to the inner end of the main support rod, the automatic opening-closing mechanism is in a loosened state, and the blade can automatically adjust the magnitude of the opening angle according to different wind forces and wind directions. When the control device drives the limiting member to slide to the outer end of the main support rod, the automatic opening-closing mechanism is in alocked state, and the two vanes of the blade are folded. Accordingly, the windward side of the blade can be adjusted automatically so as to prevent the blade from being damaged by strong wind in special occasions, such as strong wind force or typhoon.

Description

technical field [0001] The invention relates to a wind power generator whose fan blades can be opened and closed. Background technique [0002] 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 vertic...
