The invention relates to a balanced type side push hole plugging device. An air bag cabin is separated from the two sides of a side push pipe tunnel through an inner grid and an outer grid respectively; an air bag is arranged in the air bag cabin and is communicated with a pressure air source through a breather pipe; the side push pipe tunnel is provided with a pressure water inlet and is also provided with a pressure water pressure relief water outlet; the pressure of pressure water is greater than that of a pressure air source; the air bag cabin extends upwards out of the radial range of theside push pipe tunnel, and along with change of air pressure in the air bag, the air bag can contract out of the radial range of the side push pipe tunnel or open and block the side push pipe tunnel.The air bag is adopted for blocking a side pushing hole, the linear fitting degree to a ship body is high, compressed air is used for charging and discharging, blocking to a side pushing pipe tunnelis minimum, no protrusion exists outside a board, and other operations such as anchor pulling/releasing cannot be affected; meanwhile, external force borne by the left side and the right side of the ship can be directly transmitted to the other side, a balancing effect is well achieved, and a fixing reinforcing device does not need to be additionally arranged on the ship.

    本发明涉及一种平衡式侧推孔封堵装置,在侧推管隧道的两侧通过内栅格、外栅格隔出一气囊舱;气囊舱内设置一气囊,气囊通过通气管与压力气源连通;侧推管隧道设有压力水进水口,并同时设有压力水泄压排水口;压力水的压力大于压力气源的压力;气囊舱向上延伸至侧推管隧道的径向范围之外,随着气囊内气压的变化,气囊可收缩至侧推管隧道的径向范围之外或撑开并封堵住侧推管隧道。本发明采用气囊对侧推孔进行封堵,对船体线形贴合度高,利用压缩空气进行充注与放排,对侧推管隧阻挡最小,且在舷外无突出物,不会影响其它拉/放锚等作业;同时,左右舷两侧受到的外界力可以直接传递到另一侧,很好地起到平衡作用,不需在船上另设固定加强装置。
