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, the said external opening of the hull. It consists of an inflatable cylindrical bag body formed with an outer diameter that can be fitted into the ballast discharge pipe, and penetrates the bag body from one end face to the other end face in the center direction, and the other end faces the bottom of the inner wall of the ballast discharge pipe. an occlusion stopper having a first communication thin tube formed to open in the direction of the bag body and a second communication thin tube that also penetrates toward the center of the bag; a first supply/discharge hose connected to one end of the first communicating thin tube at one end surface of the blocking plug, and a second supply/discharge hose connected to one end of the first communicating thin tube at one end surface of the blocking plug; It is equipped with an air supply hose connected to allow communication, and a switching control device connected to the other end of each of the hoses to switch and control the supply and discharge of compressed air to each hose, and when it is necessary to close the external opening of the hull, , a blocking plug is inserted into the opening, and by operating the switching control device, compressed air is supplied to the first supply/discharge hose to inflate the bag body, thereby airtightly closing the opening, and the air supply/discharge hose is closed. Supply compressed air to the second
The inside of the ballast discharge pipe is pressurized through the communication capillary to extract leaked fluid from the ballast discharge pipe to the outside via the first communication capillary and the second supply/discharge hose. Supplying compressed air to the second supply/discharge hose or the air supply hose to pressurize the inside of the ballast discharge pipe via the first or second communicating thin tube, and discharging the compressed air inside the bag 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 by 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.
