Description

Technical Field

[0001] The invention relates to the technical field of marine rescue, and in particular to an air supply system for ship flip diving rescue. Background Art

[0002] The ocean environment is relatively harsh. Ships are prone to capsizing due to collisions, bad weather, improper loading, etc. When a ship capsizes, the crew members often have no time to escape and are trapped in the cabin. In this case, the trapped people are in a small space, the oxygen content in the cabin is limited, and the thermal conductivity of water is about 4 times that of air, which means that the body temperature of people in water dissipates faster than in air. The trapped people will quickly lose temperature, which endangers their lives.

[0003] At present, there are usually two ways to rescue people trapped in an overturned ship. One is underwater rescue by divers, the underwater rescue operation system of CN214190045U, and the other is to open a hole in the bottom of the ship for rescue. In the bottom hole rescue method of an overturned ship, rescuers need to cut the bottom of the hull. When the hull is cut, the air in the cabin will leak rapidly to the outside world. Due to the change in the air pressure in the cabin, the hull will drop rapidly, which brings great difficulties to the rescue work, and the escapees in the cabin will also suffer from hypoxia due to air loss, facing great life-threatening danger. Therefore, the underwater rescue method of divers is usually used to rescue the lives of people in an overturned ship.

[0004] Due to the complex underwater environment, conventional diving air supply systems have high requirements for air supply cylinders, and usually only diving cylinders can be used. In order to ensure the diving time, rescuers need to carry 50-liter cylinders, which are large and heavy, which increases the difficulty of rescue to a certain extent. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a ship flip-over diving rescue air supply system, which is mainly used to connect a single gas cylinder or multiple gas cylinders (diving gas cylinders and / or fire fighting gas cylinders) during air diving to provide diving gas sources for divers.
