Problems solved by technology
[0002] The existing underwater repair cabin is aimed at underwater oil and cable pipelines. One kind of maintenance cabin is a closed pressure cabin, which requires the help of an external carrier when working, and has poor mobility. The other is a U-shaped tube design, which can only be applied to Underwater pipeline, complex structure, inconvenient to use
At present, there are only maintenance cabins for oil pipelines in China, and there is no application of underwater dry maintenance cabins for ships.

The invention relates to a dry impermeable cabin for a ship, in particular to an underwater dry impermeable maintenance cabin for a ship. The underwater dry impermeable maintenance cabin for the ship is provided a shell which is approximately of a square shape and a steel-structured framework arranged inside the shell and characterized in that the inside of the shell is divided into a working cabin and a drainage cabin by a baffle plate arranged at the lower part of the shell, the top part and a side surface of the working cabin are respectively provided with a cabin exit, the cabin exits areclosed by cabin doors hinged on the inner wall of the working cabin and provided with cylindrical abutting interfaces in an extending way, the end parts out of the abutting interfaces are provided with flange plates, the bottom parts of the abutting interfaces are provided with water discharging valves, the two water discharging valves are communicated to the drainage cabin through pumps and drainage pipelines, and a vent valve, a drainage valve and corresponding pumps are arranged in the drainage cabin. The invention has the advantages that: the maintenance cabin has low manufacturing cost and a simple structure, is convenient to use and mainly applied to underwater dry detection, repair and the like of the ship, and can be used for realizing quick underwater repair of the ship under a condition that the ship is out of a dock.
Description
technical field [0001] The invention relates to a dry type waterproof tank, in particular to an underwater dry maintenance waterproof tank of a ship. Background technique [0002] The existing underwater repair cabin is aimed at underwater oil and cable pipelines. One kind of maintenance cabin is a closed pressure cabin, which requires the help of an external carrier when working, and has poor mobility. The other is a U-shaped tube design, which can only be applied to The underwater pipeline has a complex structure and is inconvenient to use. At present, there are only maintenance cabins for oil pipelines in China, and there is no application of underwater dry maintenance cabins for ships. Contents of the invention [0003] The object of the present invention is to provide an underwater dry maintenance waterproof tank for ships according to the above-mentioned deficiencies in the prior art. There is a replaceable sealing flange at the docking port, which can communicate ...
