Abstract

The invention discloses a sealing device for an ultra-deep water marine working ship sea chest. The sealing device comprises a sealing blind plate, a handle, screws, vertical stop round steel, horizontal stop round steel, handle round steel, sealing rubber, and water pumping valves. Small round holes are formed in the sealing blind plate. A large round hole is formed in the middle of the sealing blind plate. The handle is fixed to one side of the sealing blind plate. The sealing rubber is arranged on the other side of the sealing blind plate. The screws, the vertical stop round steel and the horizontal stop round steel are welded together to form an integral structure. The integral structure formed by the screws, the vertical stop round steel and the horizontal stop round steel is insertedin the small round holes of the sealing blind plate. The handle round steel and the screws are welded to form a rotating C-shaped component. The water pumping valves are welded to the middle large round hole of the sealing blind plate in an aligned mode. According to the sealing device for the ultra-deep water marine working ship sea chest, the sea chest can be sealed underwater, a water discharging flexible pipe is adopted to discharge water in the sea chest, and the sea chest can be maintained.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a sealing device for a seabed valve box of an ultra-deep sea working vessel. Background technique [0002] For ultra-deep sea work ships, because the ship is underwater, the interior of the submarine valve box is full of seawater and cannot be constructed normally. The conventional method can only be repaired in dry dock, but the cost of docking is extremely high. In order to reduce the cost, it is necessary to invent the submarine valve box sealing device. Contents of the invention [0003] The object of the present invention is to provide a sealing device for the seabed valve box of an ultra-deep sea work vessel which solves the underwater construction problem of the seabed valve box. [0004] The technical solution adopted by the present invention to achieve the above purpose is: a sealing device for the seabed valve box of an ultra-deep sea work vessel, including a plugging bli...
