PROBLEM TO BE SOLVED: To improve the efficiency of power generation by generating power even in the case of a lower wind speed lower than the movable starting speed of two meters in wind power generation, and to improve the efficiency of the power generation by continuously operating without stopping even in the case of a strong wind at which operation has conventionally been stopped. SOLUTION: Operation can be performed even in the case of a low wind speed by collecting winds from an area larger than a blade area of a turbine, and power generation is enabled even in the case of a strong wind by using a vertical axial flow type wind power generating device. A wind power generation system is constituted by including a turbine 3 with a rotating stand capable of rotating by itself to receive the wind where the only vane at a side receiving the wind in a central part between the nearly circular top plate 1 and a bottom plate 2 opposite to each other in apexes of venturi-type streamlines thereof protrudes to a ventilation area. A motor 11 under the turbine 3 is fixed and rotated by a gear mechanism. A wind directing plate 4 is provided at an appropriate position over the center to the outer edge of the top plate 1 and the bottom plate 2. In this case, a part of the wind directing plate 4 brought into contact with the top plate 1 and the bottom plate 2 is formed into a streamline, but it is unnecessary to form a flat surface into a streamline. The turbine 3 includes a direction blade 5 in a rod fixed to the center of the turbine 3 and protruding to pass through the top plate 1, and the direction blade is rotated dependently in the direction of wind to direct the direction of the turbine 3 in a direction corresponding to the wind. The direction blade 5 can be installed in the other place, and can be installed in a stand for rotating the turbine 3. COPYRIGHT: (C)2011,JPO&INPIT |
