PIEZOELECTRIC GENERATOR USING WIND POWER

摘要

PURPOSE: A piezoelectric generator is provided to economically obtain electric energy by applying a mechanical stimulus to a piezoelectric element. CONSTITUTION: A rotary shaft(3) is combined on a support shaft(1) by a bearing. A rotating wing is formed on the outer circumference of the rotary shaft. The rotating wing rotates the rotary shaft by the wind power. A support stand(2) is arranged on the support shaft. The support stand comprises an upper frame, a lower frame, and a pair of piezoelectric holders. The pair of piezoelectric holders are combined between the upper frame and the lower frame. A plurality of piezoelectric elements(4) is radially arranged on the support stand. A blow wing(5) is formed on the outer circumference of the rotary shaft to contact with each piezoelectric element.
