The invention relates to an air bag type sealing and closing device for an unprotected opening of a freeboard deck passing through a penetrating object, the upper part of the unprotected opening of the deck is connected with a first annular plate through a split bolt and a sealing gasket, the upper part of the first annular plate is fixedly connected with an upright cylinder, and the inner side of the cylinder is fixedly connected with a second annular plate; an annular rubber air bag is arranged between the first annular plate and the second annular plate, an inflation opening communicated with the annular rubber air bag is formed in the side wall of the barrel, the annular rubber air bag expands towards the middle after being inflated to block an unprotected opening of a deck, and meanwhile a penetrating object penetrates through the unprotected opening all the time and does not need to be moved away. The deck opening with the penetrating object does not serve as an unprotected opening any more, and the requirements of ship stability and load line convention are met; a clamp is not needed, and the problem that the clamp is inconvenient to disassemble and assemble is solved; through remote control and on-site operation, the air bag can reach different pressures to meet the requirements of different tightness.

    本发明涉及一种干舷甲板经贯穿物的未保护开口的气囊型密封关闭装置,甲板未保护开口上部通过对拉螺栓和密封垫片与第一环形板连接,所述第一环形板上方固定连接一直立的筒体,筒体内侧固定连接一第二环形板;所述第一环形板、第二环形板之间设置一环形橡胶气囊,筒体侧壁上开设与所述环形橡胶气囊连通的充气口,环形橡胶气囊充气后向中间膨胀,将甲板未保护开口封堵住,同时贯穿物始终贯穿所述未保护开口不需移走。本发明使具有贯穿物的甲板开口不再作为未保护开口,满足船舶稳性及载重线公约的要求;无需使用夹具,不会出现夹具拆装不方便的问题;可以通过遥控和就地操作,使气囊到达不同压力满足不同密性的要求。
