The invention relates to an automatic opening and closing hatch cover for a deep sea dry-wet conversion cabin. The automatic opening and closing hatch cover structurally comprises a cover plate, an opening and closing mechanism arranged on an outer side of the cover plate and a locking mechanism arranged on an inner side of the cover plate. The opening and closing mechanism is arranged to be a guide rod mechanism, the locking mechanism adopts a slider-crank mechanism and a tangent mechanism, opening, closing, locking and unlocking of the hatch cover are realized by taking an oil cylinder as adriving element, and reliability of the locking state of the hatch cover is ensured by utilizing a friction angle self-locking characteristic of a wedge-shaped surface of a locking pin and a dead point characteristic of the slider-crank mechanism; a conical surface of a cover plate serves as a supporting surface of high-pressure seawater, a stress state of the structure is more uniform and reasonable, an O-shaped sealing ring installed on the conical surface of the cover plate only has a sealing effect, and a possibility that the O-shaped ring is excessively deformed due to overlarge water pressure so that material performance is lost is avoided; and the cover body, the opening and closing mechanism and the locking mechanism of the automatic opening and closing hatch cover are integrated into a modular structure, and mounting and dismounting are convenient.

    本发明涉及一种用于深海干湿转换舱的自动启闭舱口盖,所述自动启闭舱口盖的结构包括盖板、设于盖板的外侧的启闭机构、以及设于盖板内侧的锁紧机构;其中启闭机构设置成导杆机构,锁紧机构采用曲柄滑块机构和正切机构,以油缸为驱动元件实现舱口盖的启闭与开启、锁紧与解锁,并利用锁紧销楔形面的摩擦角自锁特性和曲柄滑块机构的死点特性,保证了舱口盖锁紧状态的可靠性;本发明以盖板的锥形面作为高压海水的支撑面,结构受力状态更加均匀合理,盖板锥形面上安装的O形密封圈仅有密封作用,避免了O形圈因过大的水压产生过度变形进而丧失材料性能的可能性;自动启闭舱口盖的盖体、启闭机构和锁紧机构集成为一个模块化结构,便于安装与拆卸。
