The invention relates to a concentrated wind energy piezoelectric energy collection device. The concentrated wind energy piezoelectric energy collection device comprises a wind gathering chamber, a PVDF piezoelectric film, a clamping part, a bottom plate and a stud, wherein the wind gathering chamber and the clamping part are fixed to the bottom plate through bolts; the clamping part has upper and lower clamping plates; one end of the PVDF piezoelectric film is fixed through a bolt, so that the PVDF piezoelectric film is in a cantilever state where one end is fixed and the other end is free; the wind gathering chamber is formed through sequentially connecting a wind inlet, a contraction section and a wind outlet; the wind inlet is relatively large and faces the wind coming direction; the wind outlet is relatively small and faces the PVDF piezoelectric film; the bottom plate is fixed to the stud through a nut; and the wind gathering chamber can accelerate, rectify and uniformize wind energy, improve instability of wind energy, and improve energy flux density of wind energy. The concentrated wind energy piezoelectric energy collection device has the characteristics that the working starting wind speed is low, and the wind energy collection efficiency is high.
