Provided is a wind power apparatus which can make effective use of the energy of a weak wind irrespectively of the wind direction thereby to generate an electric power efficiently, and which can meet upsizing and power increase easily with a simple structure. The wind power apparatus comprises a wind tunnel constituted of a cylindrical member erected vertically from a foundation, a plurality of wind-collecting plates extending in the direction of the normal to the circumferential wall of the cylindrical member, a plurality of vertical guide plates disposed between the wind-collecting plates, a plurality of wind inlets for introducing the wind collected by the wind-collecting plates, into the wind tunnel, back-flow preventing means for allowing only the flow of the wind from the outside of the cylindrical member to the inside of the cylindrical member, a turbine to be driven by the wind blown from one end portion of the wind tunnel, and a power generator to be driven by the turbine. |
