Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sea rescue, in particular to a ship overturning and overturning diving rescue gas supply system. BACKGROUND

[0002] The environment on the sea is relatively bad, and ships are prone to overturning accidents due to collision, bad weather, improper loading, etc. During the overturning process of the ship, the personnel on board may not have enough time to escape and may be trapped in the cabin. In this case, the trapped personnel are in a small space, and the oxygen content in the cabin is limited. The thermal conductivity of water is about 4 times that of air, which means that the body temperature of a person in water dissipates faster than in air. The trapped personnel will quickly lose body temperature, thereby endangering the life safety of the trapped personnel.

[0003] Currently, there are two ways to rescue trapped personnel in an overturned ship. One is underwater rescue by divers, and the other is rescue through a hole in the bottom of the ship. In the rescue method of opening a hole in the bottom of the overturned ship, the rescue personnel need to cut the bottom of the ship. When the ship body is cut, the air in the cabin will quickly leak to the outside. Due to the change in air pressure in the cabin, the ship body will quickly descend, causing great difficulty for rescue work, and the escape personnel in the cabin will also face great danger due to air loss and lack of oxygen. Therefore, the method of underwater rescue by divers is usually used for life rescue in an overturned ship.

[0004] Due to the complexity of the underwater environment, the conventional diving gas supply system has high requirements for the gas cylinder, and only diving cylinders can be used. In order to ensure the diving time, the rescue personnel need to carry a 50-liter cylinder, which is large in size and heavy in weight, increasing the difficulty of rescue to some extent.
