The invention provides an automatic manhole cover plate opening and closing device which comprises a manhole seat ring mechanism, a manhole cover plate mechanism and a driving mechanism. The manhole seat ring mechanism comprises a manhole seat ring, the manhole cover plate mechanism comprises a manhole cover plate, the manhole cover plate is located above the manhole seat ring, a sealing ring is arranged at the bottom of the manhole cover plate, and the driving mechanism is in transmission connection with the manhole cover plate, so that the manhole cover plate can move in the transverse direction and the vertical direction, and the sealing ring is pressed between the manhole cover plate and the manhole seat ring. The manhole cover plate can move in the horizontal direction and the vertical direction by adopting a single power source, the multi-dimensional motion trail action of the manhole cover plate is achieved through ingenious structural design, the demand of the opening and closing device for the power source is reduced, the production and manufacturing cost is reduced, and meanwhile the device is compact in overall structure and lighter in weight. Workers do not need to climb up a tank body to open or close the manhole cover plate, so that the labor intensity is reduced, and the potential safety hazard caused by manual operation is avoided.

    本发明提出了一种人孔盖板自动开合装置,包括:人孔座圈机构,所述人孔座圈机构包括人孔座圈;人孔盖板机构,所述人孔盖板机构包括人孔盖板,所述人孔盖板位于所述人孔座圈上方,其底部设有密封圈;驱动机构,与人孔盖板传动连接,使人孔盖板能在横向和竖直方向运动,从而将密封圈压紧在人孔盖板和人孔座圈之间。本发明采用单一动力源能够使人孔盖板在水平方向以及竖直方向上进行运动,通过巧妙的结构设计实现了人孔盖板的多维度运动轨迹动作,减少了开合装置对动力源的需求量,降低生产制造成本的同时,使装置整体结构紧凑,重量更轻;且不需要人工爬上罐体进行人孔盖板的开合操作,降低了劳动强度,杜绝了人工作业带来的安全隐患。
