Fresh water supply system for large-depth saturated diving decompression chamber

Abstract

The invention relates to a fresh water supply system for a large-depth saturated diving decompression chamber, which comprises a residence chamber which is divided into a main chamber and an auxiliary chamber, the system further comprises a water storage tank, a mixer and a distributor; a temperature controller is arranged at the inlet end of the mixer and is simultaneously connected with a hot water pipe and a cold water pipe; the water storage tank is communicated with the mixer through a pipeline and is used for temporarily storing fresh water; a pumping pipeline is arranged between the mixer and the distributor, the high-pressure pump set is installed on the pumping pipeline, a check valve for preventing fresh water from flowing back to the high-pressure pump set is arranged on the pipeline from the high-pressure pump set to the distributor, the mixer and the distributor are further provided with a communicated return pipeline, and a release valve is arranged on the return pipeline. The distributor is provided with two water supply pipelines which are communicated with the main cabin and the auxiliary cabin respectively, each water supply pipeline is provided with a check valve for preventing fresh water from flowing back to the distributor, and each water supply pipeline is provided with an out-cabin valve and an in-cabin valve which are located on the outer side of the living cabin.

Description

technical field [0001] The invention relates to a fresh water supply system for a deep saturated diving decompression chamber, belonging to the technical field of water supply systems for a diving decompression chamber. Background technique [0002] The saturation diving system is composed of living quarters, diving bells and other equipment. The general process of saturation diving is: before the start of saturation diving operations, divers live in the living quarters, and pressurize according to the prescribed procedures so that the inert gas in the diver's body is at the predetermined operating depth. When it reaches saturation, when it is necessary to carry out diving operations, the diver enters the diving bell with the same pressure from the living compartment, and then the diving bell carrying the diver is hoisted by the winch to the submarine diving operation site, and the diver swims out of the diving bell to the sea after wearing the diving suit. Operation, after ...

Problems solved by technology

[0003] Among them, the living cabin is an important living place for divers, and divers can live in it for dozens of days. During this period, divers will need a lot of fresh water for daily activities such as showering and washing, and the living cabin needs to maintain a high environmental pressure. Under the circumstances, how to provide safe, timely, and temperature-appropriate supply of daily fresh water for divers in the living cabin is a major problem. In particular, when carrying out large-depth saturation diving, such as 1000 meters, the pressure in the living cabin can reach 10MPa at this time. The constant supply of fresh water for everyday life becomes difficult to handle

At present, there is no fresh water supply system in the world that can work at a large depth for saturation diving cabins, making it a difficult problem to supply fresh water safely, continuously and at a suitable temperature for saturation diving cabins
