<p>PURPOSE: A vertical wind power generator is provided to increase generation efficiency according to wind speed by varying the area of a blade according to wind speed. CONSTITUTION: A vertical wind power generator comprises a rotary shaft(110), a vertical blade(130), and a generating unit(150). The rotary shaft is vertically formed on the surface. The vertical blade is installed in the rotary shaft. The vertical blade rotates the rotary shaft with the wind force. The area of the vertical blade, contacted with the wind, is varied according to wind speed. The generating unit generates electric energy using the rotation of the rotary shaft.</p> |
