Embodiment Construction
[0018] In the invention, the energy collected by the wave energy collector acts on the piezoelectric vibrator in the form of instantaneous load, so that the piezoelectric vibrator vibrates at a natural frequency, thereby obtaining higher conversion efficiency and output electric energy. The frequency of the output current can maintain the design value and is not affected by the external vibration frequency to increase. Because the frequency is increased (such as 10-120Hz), the output electric energy is easier to be utilized. The present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings.
[0019] Such as figure 1 , figure 2 As shown, the present invention includes a wave energy harvester 1 and one or more piezoelectric generating units 2 arranged on the wave energy harvester 1 . A piezoelectric generating unit 2 is taken as an example below.
[0020]The wave energy harvester 1 includes a U-shaped supporting floatin...
