Abstract

The invention discloses a piezoelectric energy conversion and collection device using bridge vibration, and belongs to the technical fields of microelectronics and mechanical design. The device comprises a piezoelectric component group, a piezoelectric accumulator, a shell and the like; the piezoelectric accumulator is arranged in the shell and protected; the vertical height of the shell is smaller than the height of each plate-type rubber support; and the piezoelectric accumulator comprises the piezoelectric component group, an alternating current / direct current (AC / DC) amplifying circuit module, a high-capacity capacitor, a power management chip and a lithium battery which are sequentially in input and output serial connection. The piezoelectric component group consists of a plurality of piezoelectric components connected in parallel, each piezoelectric component is horizontally placed, and the lateral surface of each piezoelectric component is adjoined to the bottom contact face of a bridge. A piezoelectric vibration source is from vibration produced by impact when a high speed railway passes through a track, the vibration is transferred to the lower bridge through the track, mechanical vibration produced after the bridge is vibrated is converted into electrical energy through the piezoelectric accumulator, and the electrical energy is stored in the lithium battery, so that the problem about recovery of energy produced by vibration of the bridge is solved, and effects of saving energy and protecting environment are achieved.
