More Information
Summary:The invention discloses a wave power generation device based on a piezoelectric element. Inner and outer sleeves are mounted below wave acquisition floating bodies, so that one parts thereof are below the sea surface to prevent the problem of weak stability caused by such external factors as sea breeze. A limiting device is adopted to replace a rigid connecting mode between a cross bar and a truss rod piece in the prior art to realize the fixation of the inner and outer sleeves, so that the shaking of the inner and outer sleeves due to seawater impact is prevented. In addition, wave power acquisition devices all generate resonance through the design of the masses of the wave power acquisition floating bodies and the elastic coefficients of springs, so that the wave power conversion efficiency is improved.
