vertical wind generator

vertical wind turbine generator
blade automatic regulate its windward side wind turbine
start-up wind speed is 1.8m/s
small size wind turbine generator













we have unique features:






1. Blade can automatically regulate its windward side.




2.Its windward side is concave curved, which can catch the maximum of wind thus fully obtain wind energy.
3. Blade can automatically regulate its windward side. Windward side ascertained is traced by sensor of dogvane
4. When it is stormy wind, anemometer can change the windward angle by wind sensor,

thus to get a constant rotating speed





5. Brake protection device, when there is stormy wind,the back side of the blade; the hydraulic retractable
spear automatically shrinks itself to make windward side change its angle to face to the wind,

thus reduce the windward area all features have rewarded national patent.
