Submarine ventilation device

Abstract

The invention discloses a submarine ventilation device which comprises a gas supply pipeline, an exhausting pipeline and a connecting pipeline between the gas supply pipeline and the exhausting pipeline. The connecting pipeline is provided with a valve capable of being opened and closed. Valves are arranged at the two ends of the gas supply pipeline. Valves are arranged at the two ends of the exhausting pipeline as well. A pressure adjuster is further arranged at the high-pressure gas supply opening end of the gas supply pipeline. High-pressure gas of the gas supply pipeline is used for reversely blowing away accumulated water of the exhausting pipeline, the water amount of the accumulated water left in the exhausting pipe and entering a submarine cabin is reduced, the underwater operation difficulty of a diver is lowered, and it can be controlled that the pressure in the submarine cabin is kept unchanged in the ventilation process. Gas exchanged and exhausted from the submarine cabin is monitored in real time through a gas acquisition opening, and ventilation is adjusted in real time pertinently. The submarine ventilation device is simple in structure and convenient to operate, the diver only needs to connect the gas supply pipeline and the exhausting pipeline with joints of a submarine in a butt joint manner, and the efficiency of a conventional rescue submarine is greatly improved.

Description

technical field [0001] The invention relates to a submarine rescue device, in particular to a ventilation device used in submarine rescue. Background technique [0002] When a submarine fails to float due to a crash, it is usually necessary to ventilate it during rescue. The current ventilation device is relatively simple, the air supply and exhaust are separate pipelines, and there are many problems: as when the cabin is ventilated, the accumulated water in the exhaust pipe enters the submarine cabin with a large amount of water; It is difficult to control the pressure of the cabin when it is out of air; it is difficult for divers to operate underwater. Moreover, since it is impossible to detect and analyze the gas discharged from the submarine cabin in real time, it is also impossible to adjust the ventilation in real time in a targeted manner. Contents of the invention [0003] In view of the problems referred to above, the purpose of the present invention is to provi...

Problems solved by technology

The current ventilation device is relatively simple, the air supply and exhaust are separate pipelines, and there are many problems: as when the cabin is ventilated, the accumulated water in the exhaust pipe enters the submarine cabin with a large amount of water; It is difficult to control the pressure of the cabin when the air is out; it is difficult for divers to operate underwater, etc.

Moreover, since it is impossible to detect and analyze the gas discharged from the submarine cabin in real time, it is also impossible to make real-time adjustments to the ventilation in a targeted manner.
