Abstract

The invention relates to an airflow-induced vibration piezoelectric generator, which belongs to the technical field of new energy sources. The front and rear frames are equipped with upper and lower beams and arc-shaped plates and beams connecting the upper and lower beams. The inner concave surface of the arc-shaped plates is close to the side of the beam; There is a square groove on the top, the opening of the square groove and the shape-limiting surface are located on the same side of the beam; the front and rear frames are connected by screws, and the shape-limiting surface on it and the opening of the groove above the arc-shaped plate are respectively installed facing each other. It constitutes a baffle; a reed and two piezoelectric vibrators are crimped between the beams of the front and rear frames; the free end of the reed is connected to the ear plate of the blunt body through a pressure plate and screws, both of which are of T-shaped structure and Its narrow end is located in the square groove of the arc-shaped plate, and the two ends of the blunt body are located inside the upper and lower beams; the piezoelectric vibrator is composed of a substrate and a piezoelectric sheet bonded to one side, the substrate and the reed are wider than the piezoelectric sheet, and the substrate One side is in contact with the reed, and the root of the fixed end on the other side is tangent to the constrained surface.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to an airflow-induced vibration piezoelectric generator, which is used for recovering the kinetic energy of airflow in a tunnel. Background technique [0002] Tunnels have become an important part of the current road and rail network. In order to ensure the normal and safe passage of cars and trains and to realize the real-time monitoring of the tunnel environment and passing vehicles, various instruments and lighting facilities need to be installed in the tunnel, so there must also be corresponding power supply facilities in the tunnel. If the traditional cable is used for power supply, the cable laying and subsequent maintenance are more difficult and costly; if the battery is used for power supply, due to the limited life of the battery, it needs to be replaced frequently, which is extremely inconvenient to use, especially in remote mountainous areas.
