The invention belongs to the energy gathering field based on piezoelectric materials, and relates to a wind energy conversion device, in particular to a wind-induced vibration piezoelectricity energy gathering device. The wind-induced vibration piezoelectricity energy gathering device is characterized in that a support is fixedly installed on a fixing seat, a rotation shaft with a bearing installed on is fixedly installed on the support, a fan is fixed on the rotation shaft, a housing is fixedly installed on the support, a plurality of cantilever beams are fixed inside the housing, the cantilever beams are symmetrically distributed, a piezoelectric film is pasted on the surface of each cantilever beam, each piezoelectric film is pasted from the fixing end of each cantilever beam to the free end of each cantilever beam, certain space is kept between each piezoelectric film and each of the fixing and the free end of each cantilever beam, the free end of each cantilever beam overlaps a vane of the fan, the overlap distance is M, and the deformation degree of each cantilever beam is controlled through the overlap distance M between the vane of the fan, which overlaps the cantilever beam, and the cantilever beam. The wind-induced vibration piezoelectricity energy gathering device has the advantages of being simple in structure, low in cost, and easy to achieve, and can supply power for a miniature device and a wireless sensing network.
