A wind turbine single-frame impeller comprising a wind wheel frame (1), a blade regulation apparatus, a support base (6), and inclined support rods (4); the blade regulation apparatus and the support base are connected and fitted to the front end of the main shaft of the turbine (7); the wind wheel frame is connected to the support base by means of the inclined support rods; blades encircle the blade regulation apparatus and are fitted within the wind wheel frame by means of shafts; the blade regulation apparatus is provided with a sealed regulation compartment (5); the regulation compartment is internally fitted with a gear-type, rack and pinion-type, or connecting rod-type composite regulation mechanism. The present impeller increases wind energy utilization efficiency, magnifies overall output power, reduces fault rates, and increases safety, reliability, and economy. |
