Vertical axis windmill with wingletted air-tiltable blades |
摘要 |
A vertical axis windmill includes a generator, a shaft mounted to the generator, and a plurality of blade sets. The blade set includes a blade rod rotatably connected to the shaft and carrying blades arranged on opposite sides of the shaft. Each blade is divided into first and second moment-inducing sections located on opposite sides of the blade rod. The first moment-inducing section is greater in area than the second moment-inducing section. Each blade is provided, at a predetermined location thereof, with a winglet. Stops for limiting swiveling of the blade are arranged on the blade set. When the blade set is moved so that the blades thereof are located in a windward position and a leeward position respectively, the blades are automatically and easily set at an optimum pressure-receiving condition and a least wind-resistance condition respectively, for receiving wind energy from variable directions. |
