The invention belongs to the technical field of anti-static, and particularly relates to an anti-static grounding device for an oil tank truck; the anti-static grounding device comprises a shell and an electrostatic belt which are fixedly mounted on the oil tank truck, the upper surface of the shell is fixedly connected with a wing plate through an extension spring, the upper surface of the wing plate is in an upwards arched arc shape, and the lower surface of the wing plate is a horizontal plane; a threaded cylinder is rotationally connected to the inner top surface of the shell, a rotor is arranged outside the threaded cylinder, a permanent magnet ring matched with the rotor is mounted on the inner side wall of the shell, a threaded rod is fixedly connected to the lower surface of the wing plate, the lower end of the threaded rod penetrates through the shell and is in threaded fit with the threaded cylinder, and a sliding cylinder is fixedly connected to the lower end of the shell; and the sliding cylinder is made of a conductive material and is electrically connected with the oil tank truck body. When oil in the oil tank shakes to generate static electricity, the static electricity belt can make contact with the ground, and the problem of fire disasters caused by static electricity flashover is prevented; and when a vehicle runs stably, the static electricity belt does not make contact with the ground, and friction and electric sparks are avoided.
本发明属于防静电技术领域,尤其是涉及一种油罐车用防静电接地装置,包括固定安装在油罐车上的壳体和静电带,所述壳体的上表面通过拉伸弹簧固定连接有翼板,所述翼板的上表面呈向上拱起的弧线形,下表面为水平面,所述壳体的内顶面转动连接有螺纹筒,所述螺纹筒外设有转子,所述壳体的内侧壁上安装有与转子匹配的永磁环,所述翼板的下表面固定连接有螺纹杆,所述螺纹杆的下端贯穿壳体并与螺纹筒螺纹配合,所述壳体的下端固定连接有滑筒,所述滑筒由导电材料制成并且与油罐车体电连接。本发明可在油罐内的油晃动产生静电时,使静电带与地面接触,防止静电跳火而发生火灾的问题发生,在车辆平稳行驶时,静电带不与地面接触,避免产生摩擦和电火花。
