Multi-directional wind power generator

Abstract

The present invention relates to a wind power generator, and more particularly, to a multi-directional wind power generator capable of maximizing use efficiency of wind as well as enabling effective power generation regardless of the wind direction. The multi-directional wind power generator of the invention can generate electric power regardless of wind direction as well as minimize the resistance against the wind thereby enhancing its efficiency.

1 . A multi-directional wind power generator comprising: 
 a base frame having a central shaft and being supported on the ground, disposed around the central shaft defining a space of a predetermined radius;    a first rotary shaft rotatably fitted around the central shaft of the base frame;    a plurality of first upper/lower support frames extended from upper and lower outer peripheries of the first rotary shaft to a predetermined radius;    first rotary blades hinged by their both ends, respectively, on distal ends of the first upper/lower support frames;    first anti-pivoting bars disposed, respectively, at portions of the first upper/lower frames to prevent pivoting of the first rotary blades so that the first rotary blades are oriented parallel with the first upper/lower support frames;    first control means disposed respectively in the first upper/lower support frames for controlling pivoting of the first rotary blades;    rotation power transmission means disposed around a lower portion of the central shaft of the base frame to transmit the rotation power of the first rotary shaft at a rotation rate changed via gear combination; and    a generator for generating electric power under the rotation power transmitted from the rotation power transmission means.    
     
     
         2 . The multi-directional wind power generator of  claim 1 , further comprising: 
 first to third rotation shafts fitted around the first rotation shaft in the order of the first to third rotation shafts;    a plurality of first to third upper/lower support frames extended, respectively, from upper and lower outer peripheries of the first to third rotary shafts to respective predetermined radii of rotation;    first to third rotary blades hinged by their both ends, respectively, on distal ends of the first to third upper/lower support frames to rotate in the wind;    first to third anti-pivoting bars disposed, respectively, at portions of the first to third upper/lower frames to prevent pivoting of the first to third rotary blades at respective positions;    first to third control means disposed, respectively, on the first to third upper/lower support frames for controlling pivoting of the first to third rotary blades;    first to third drive gears coupled, respectively, with one ends of the first to third rotation shafts extended into the gear housing; and    first to third driven gears meshed, respectively, with the first to third drive gears at respective rotation rates.    
     
     
         3 . The multi-directional wind power generator of  claim 1  or  2 , wherein the first to fourth pivoting-control means are stopper protrusions which are formed, respectively, at both sides of one ends of the first to fourth upper/lower support frames to contact, respectively, one sides of the first to fourth rotary blades.
