Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of saturation diving, specifically, the utility model relates to a highly integrated saturation chamber fire -fighting sprinkler system. BACKGROUND

[0002] Commercial diving is divided into air diving, mixed gas diving and saturation diving, the former two are simple in equipment, but long in decompression time and low in operation efficiency. Saturation diving is a diving mode suitable for large depth conditions and long time operation.

[0003] The principle of saturation diving is that the diver stays in a high pressure environment at a certain depth under water or equivalent to the environmental pressure of the depth, and the neutral mixed gas (helium, nitrogen) in the breathing gas is gradually dissolved into the human tissue. If the staying time is long enough (more than 24 hours), the partial pressure of the neutral gas in the human tissue reaches the balance state (complete saturation) with the partial pressure of the neutral gas in the breathing gas. In this case, the diver can stay at the depth for as long as he wants, and the partial pressure of the neutral gas in the human tissue will not increase, and the decompression time will not increase due to the extension of the staying (diving) time. Therefore, the diving operation time is greatly extended under the condition that the decompression time is basically unchanged. In this way, the diver can stay under water for a long time until the underwater operation task is completed, and then return to the water surface (normal pressure) for one-time inspection.

[0004] Advantages of saturation diving:

[0005] (1) greatly expand the diving depth and time

[0006] Saturation diving greatly expands the diving depth and extends the diving operation time, which is theoretically unlimited. Saturation diving is also the latest achievement of diving technology in the world.

[0007] (2) greatly improve the diving operation efficiency

[0008] Saturation diving not only has advantages in deep diving, but also has diving operation efficiency that cannot be reached by conventional diving.

[0009] Because saturation diving greatly expands the diving depth and increases the diving operation time, the diving operation efficiency is greatly improved. Saturation diving technology has been widely used in deep underwater salvage operations in developed countries.

[0010] In the saturation diving system, the supporting decompression chamber needs to be equipped with a fire fighting system. Because the pressure in the decompression chamber is high, the conventional fire fighting system cannot be used. Therefore, a fire fighting system suitable for saturation environment needs to be configured. SUMMARY
