Abstract

The invention relates to a tunnel airflow-induced vibration generator, which belongs to the technical field of new energy sources. The bracket is provided with an upper beam with an upper slideway, a lower beam with a slideway and a baffle connecting the upper and lower beams, the two ends of the lower beam are provided with feet, the baffle is placed at one end of the upper and lower beams and the upper and lower beams are installed oppositely; Both ends of the fixed pin and the movable pin are covered with pin sleeves, the fixed pin and the movable pin are hinged with the pin sleeves, and the pin sleeves are placed in the upper and lower slideways; the piezoelectric vibrator is sleeved in the stepped groove of the movable pin, and one end of the piezoelectric vibrator is fixed on the fixed pin by a screw. In the stepped groove of the pin, the other end is connected to the lug plate of the blunt body through screws. The blunt body is installed near the side of the baffle. The blunt body is a hollow cylindrical shell and its center line is located in the vertical plane; The symmetrical center layer in the thickness direction, the centerline of the fixed pin and the movable pin, the centerline of the blunt body, and the symmetrical center layer in the width direction of the baffle are located in the same vertical plane; the piezoelectric vibrator is bonded by the substrate and its two sides or one side. connected piezoelectric film.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a tunnel airflow-induced vibration generator. 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. Contents of the invention [0003] The present invention proposes a tunnel airflow-induced...
