| description | The invention discloses a bicrystal cantilever beam type piezoelectric power generation device, and belongs to the technical field of power generation devices. The power generation efficiency is improved, and elements can be protected. Comprising a wave energy capture mechanism, an energy conversion and transmission mechanism and a power generation mechanism, the repulsive force between the magnets is used for causing vibration of the cantilever beam, the spring and the piezoelectric vibrator are used for increasing frequency, and wave energy is collected and converted. The influence curve of structural parameters on voltage and power generation capacity is obtained through simulation calculation, Comsol is adopted to conduct simulation analysis on the relation among the cantilever beam length, the inherent frequency and the output voltage of the device, and the rule that the first-order inherent frequency and the power generation capacity of the system change along with the cantilever beam length is obtained |
