The invention discloses a hole plugging device which acts on a to-be-sealed plate, the to-be-sealed plate is provided with a through hole, and the hole plugging device comprises a working air bag, an inflation air bag, an inflation valve and a sealing piece; the working air bag comprises a bag body, an air inlet pipe and an air outlet pipe. The air inlet pipe and the air outlet pipe are both communicated with the inner cavity of the bag body; the inflatable air bag is connected with the air inlet pipe and is used for inflating and deflating the bag body; the inflation valve is arranged on the air inlet pipe; the inflation valve is a one-way valve; the sealing piece is arranged on the air outlet pipe; the working air bag is inflated through the inflation air bag, so that the working air bag is expanded until part of the surface of the working air bag can be attached to the inner wall of the through hole, and the through hole is blocked. The through hole is blocked through the working air bag, rainwater falling in rainy days or water used for construction can be prevented from leaking to the next layer of deck or flowing into the dry cabin through the through hole of the to-be-sealed plate, dryness in the cabin is guaranteed, and the internal functions of a ship can be normally operated.
本发明公开一种孔洞封堵装置,作用于待封板,待封板开设有通孔,孔洞封堵装置包括工作气囊、充气气囊、充气阀以及封口件;工作气囊包括囊体、进气管以及出气管;进气管以及出气管均与囊体的内腔相连通;充气气囊与进气管连接,用于实现囊体的充气和放气;充气阀设置于进气管;充气阀为单向阀;封口件设置于出气管;其中,通过充气气囊对工作气囊进行充气,使工作气囊膨胀至其部分表面能够贴合于通孔的内壁,以封堵通孔。通过工作气囊对通孔形成封堵,可以有利于避免雨天下落的雨水或施工所用的水通过待封板的通孔渗漏至下一层甲板或流进干舱内,保证舱内干燥使船舶内部功能能够正常运行。
