Claims

[Scope of utility model registration request]

(1) A closing device that temporarily closes the external opening of a ballast discharge pipe, one end of which communicates with the pump chamber of the hull, and the other end of which opens outside the hull at a side skin plate, and which A closure stopper consisting of an inflatable cylindrical bag formed with an outer diameter that can be fitted into an opening and a communicating thin tube passing through the center is arranged, a first supply/discharge hose that is communicatively connected; a second supply/discharge hose that is communicatively connected to the communication thin tube at one end surface of the blocking plug; and a second supply/discharge hose that is connected to the other ends of both supply/discharge hoses. and a switching control device that switches and controls the supply and discharge of compressed air to and from the exhaust hose, and when it is necessary to close the above-mentioned external hull opening, a blocking plug is inserted into the opening, and by operating the switching control device, the first supply By supplying compressed air to the discharge hose and inflating the bag body, the opening is airtightly closed, and the leaked fluid from the ballast discharge pipe is extracted to the outside through the communication thin tube and the second supply/discharge port, while the opening is closed. When unnecessary, the switching control device is operated to supply compressed air to the second supply/discharge hose to pressurize the inside of the ballast discharge pipe via the communicating thin tube, and to supply compressed air inside the bag body via the first supply/discharge hose. A ballast discharge pipe closure device for a ship, characterized in that the closure plug can be automatically taken out from the opening to the outside by discharging the bag and deflating the bag.

(2) The ballast discharge pipe closing device for a ship according to claim (1), wherein the closing plug has an appropriate number of annular bands around the outer periphery of the bag.
