Patent ID: 8836159

Claim:
A compound-type wind power generator, comprising: a propeller wind turbine including a plurality of propeller blades mounted to a horizontal rotation shaft; a Magnus wind turbine including a plurality of cylindrical rotation members having helical protrusions on their outer surfaces and rotating about perpendicular center shafts which rotatably support the cylindrical rotation members, respectively, and a transmitting mechanism for transmitting a rotational force of the cylindrical rotation members rotating about the perpendicular center shafts to a horizontal rotational shaft; generators respectively driven by the horizontal rotation shaft of the Magnus wind turbine and the horizontal rotation shaft of the propeller wind turbine; and a fixing unit for fixing an outer end of the perpendicular center shaft of each Magnus wind turbine to the adjacent propeller blade, wherein the horizontal rotation shaft of the propeller wind turbine and the horizontal rotation shaft of the Magnus wind turbine are constituted by a double shaft structure in which one of the horizontal rotation shafts is formed by a cylindrical member and another one the horizontal rotation shafts is axially inserted through the cylindrical member with a play therebetween, and wherein the cylindrical rotation members of the Magnus wind turbine are spaced apart from the propeller blades in a rotating direction of the propeller blades.
