A multi-stage wind power generator having multiple spiral blades is provided to maintain the total power for converting continuous wind power to electrical energy at high efficiency through a multiple spiral rotary member installed on the circumference of a vertical main shaft. A multi-stage wind power generator includes a first housing(10'), a second housing(10''), a third housing(10), a vertical main shaft and a rotary member(30). Both ends of the third housing are supported by main shaft bearings in the vertical main shaft. The rotary member has multiple spiral blades formed on the outer side of a rotary member plate. The rotary member plate is installed by a support member in the shape of a cylinder around the vertical main shaft. |
