<P>PROBLEM TO BE SOLVED: To provide a wind velocity measuring device easy in installation and capable of measuring an instantaneous wind velocity, and a wind power generation system capable of supplying electric power to the outside. <P>SOLUTION: The wind power generator comprises a wind force transmission mechanism (1) having a vertical axis wind turbine, and vertical grooves provided to a plurality of poles circumferentially installed in the inside of a cylinder having a center axis commonly with the vertical axis wind turbine, at an upper part, a lower part or the inside of the vertical axis wind turbine; and a power generating mechanism (2) having a piezoelectric element member whose one end is fixed to a fixing holding member pivotally supported by a center axis of the vertical axis wind turbine and which is vertically overhung from the center axis to the circumference and generates power by bending, and a force-receiving plate mounted on the other end where the piezoelectric element member is not fixed and vibrating by being periodically pushed so as not to be dislocated from the vertical groove and generating power by transmitting the vibration to the piezoelectric element member. <P>COPYRIGHT: (C)2013,JPO&INPIT |
