Abstract
The utility model relates to an automatic speed regulation device for a wind turbine, and the device belongs to the manufacturing technology field of the power generation equipment, and includes a rotor wing, a rotor wing seat, a spindle, an active friction wheel, a centrifugal gravity pendulum mechanism and a slave friction wheel, wherein, the rotor wing is hinged to the rotor wing seat through a rotor wing pivoted axle, the rotor wing seat is concentric to the spindle and is fixed into an integrity. The spindle is coupled with the active friction wheel and the sliding sleeve which are connected with the centrifugal gravity pendulum mechanism, the active friction wheel and the slave friction wheel are driven by the friction surface matching, and the transmission ratio is adjusted by the centrifugal gravity pendulum mechanism. The rotor wind drives the spindle to rotate under the action of the wind force during the application. When the speed of the spindle is risen up, the rotor wing pivoted arm is expanded outwards under the action of the centrifugal force, the connection rod draws back the sliding sleeve, so the active friction wheel continuously moves to the outer edge of the slave friction wheel during the rotation process, thereby changing the transmission ratio between two friction wheels, the rotation speed of the slave friction wheel is kept relatively constant. The utility model has the advantage of rational design, simple structure, convenience, practicality, etc.
