Abstract:
1. A wind power generator comprising: a columnar member forming a wind tunnel in a vertical direction, the columnar member erected on a surface of a foundation; a plurality of adjacent wind-collecting plates that extend from a circumferential wall of the columnar member in directions normal to the circumferential wall; a top plate that closes an upper end opening of the columnar member and closes upper end openings of spaces between adjacent wind-collecting plates; a plurality of wind inlets that are formed on the circumferential wall of the columnar member to introduce wind collected by the wind-collecting plates into the wind tunnel; a first back-flow preventing means arranged at the wind inlets for allowing the wind to flow inside of the columnar member from outside of the columnar member, while regulating the flow of air from the inside to the outside of the columnar member; a plurality of guide plates arranged between the adjacent wind-collecting plates for guiding the wind collected by the wind-collecting plates downward through the wind tunnel; a turbine that is driven by the wind flowing out from one end of the wind tunnel; a power generator driven by the turbine; and a second back-flow preventing means arranged between outer portions of the adjacent wind-collecting plates for allowing the flow of wind from the outside to the inside of the wind power generator, while regulating the flow of air from the inside to the outside of the wind power generator.
