Vibration energy recovery device

The invention discloses a vibration energy recovery device, belongs to the technical field of energy recovery and utilization, and solves the technical problem of how to utilize vibration energy of a high-frequency train to generate power due to strong vibration generated by a track and a road nearby the track when the existing heavy-load train runs on the track. Comprising a stress rod, a mounting seat, a generator, a rotating device and a transmission device, one end of the stress rod is hinged to the mounting seat; the rotating device comprises a rotating shaft, supporting seats and a gear set, the two ends of the rotating shaft are rotationally connected with the two supporting seats correspondingly, and the rotating shaft is in transmission connection with a main shaft of the generator through the gear set; the transmission device enables the stress rod and the rotating shaft to be in transmission connection, and when the stress rod swings up and down, the transmission device drives the rotating shaft to
