APPARATUS FOR PIEZOELECTRIC POWER GENERATION UTILIZING WAVE ENERGY

摘要

PURPOSE: A piezoelectric power generation using wave energy is provided to generate electricity with an environmentally-friendly method by allowing the piezoelectric element pressing part to move up and down according to the up and down motions of a float. CONSTITUTION: A piezoelectric power generation using wave energy comprises a float(110), a connection part(120), a vertical support(130), and a piezoelectric generator(140). The float moves up and down with wave and provided with an anchor(111) for limiting the range of up-and-down motion. The connection part is coupled with the float on an end and supported by the vertical support. The piezoelectric generator comprises a piezoelectric generating part(141) which is connected to the other end of the connection part and generates electricity by driving a piezoelectric element and a piezoelectric element pressing part(142) which presses the piezoelectric element from above to drive a piezoelectric element. The up and down motion of the float is transmitted to the piezoelectric element pressing part through the connection part so that the piezoelectric element pressing part applies pressure to the piezoelectric element.
