  • Patent number: 7345375
    Abstract: Disclosed relates to a wind power generation apparatus and, more particularly, to a multi-direction wind power generation apparatus, which can be easily, solidly and largely manufactured and also repaired readily, for enhancing the efficiency of power generation by making most us of wind and by lessening the wind resistance. The object of the present invention is to provide the multi-direction wind power generation apparatus that can generate electricity against the wind blowing from various directions, enhance the efficiency of electric generator by lessening the wind resistance maximally, and increase the solidity of the apparatus by establishing separate supporters for supporting the upper/lower support frames.
    Type: Grant

  • Patent number: 7044713
    Abstract: A wind power generating apparatus having a plurality of rotary wings can reduce the load and resistance on the rotary wings due to wind to obtain a highly effective rotation power as well as to flexibly absorb the impact applied to the rotary wings due to varying wind pressure. Each one of the rotary wings has a radius of rotation different from the others and rotates separately according to the direction of the wind, by which the rotation power resulting from load and resistance in the integrally elongated rotary wings in relation to the wind is prevented from being canceled, and the wind acceleration via the accelerator covers and the wind distribution to the rotary wings result for highly efficient rotation power.

  • Publication number: 20050141994
    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.

The wind power generating apparatus of the invention can reduce the load and resistance occurring to the rotary wings in relation to the wind to obtain high effective rotation power as well as flexibly absorb impact applied to the rotary wings according to variation of wind pressure. The wind power generating apparatus comprises a number of rotary wings, which have radii of rotation different from one another and rotate separately according to the direction of the wind. The wind power generating apparatus of the invention can prevent canceling of rotation power resulting from load and resistance in the integrally elongated rotary wings in relation to the wind as well as accelerate the wind via accelerator covers and distribute the wind to rotary wings to obtain high efficient rotation power.
