Wave power generation device based on piezoelectric element

一种基于压电元件的波浪能发电装置

Abstract

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.
本发明公开了一种基于压电元件的波浪能发电装置。本发明通过将内外套筒安装于波浪采集浮体的下方,使部分将位于海面以下,进而避免了由于海风等外在因素而导致稳定性差的问题。本发明还通过采用限位装置代替现有技术中横杆和桁架杆件刚性连接的方式,以实现固定内外套筒,避免内外套筒由于海水冲击而导致其晃动。此外,通过对波浪能采集浮体质量、弹簧弹性系数的设计,使得波浪能采集装置均发生谐振,提高波浪能转换效率。
