風力発電装置
Document Type and Number:
Japanese Patent JP4792296
Kind Code:
B2
Abstract:
To provide a wind power generator which can generate electricity by vibrating a vibrator using wind power, and by vibrating a flexible piezoelectric element thereby while suppressing the destruction.
The wind power generator 10 has the vibrator 11 which has a flat tape-like shape and holds the longitudinal ends to apply a predetermined tension in the longitudinal direction; and a piezoelectric element 12 which is shaped in a rectangular plate installed in at least one of the longitudinal ends of the vibrator 11. The vibrator 11 generates arc vibration by the wind blowing in the parallel direction to the main plane to extract electric energy by bending the piezoelectric element 12 with the vibration.
