Description

Technical Field

[0001] The utility model relates to the technical field of diving equipment, in particular to a hot and cold water washing device with adjustable temperature used in a saturated cabin. Background Art

[0002] As an important underwater operation method in modern marine engineering, saturation diving has been widely used in submarine pipeline installation, inspection, conventional marine engineering and salvage services. Saturation diving is to create an environment and conditions so that the inert gases dissolved in the body fluids of the diver's body tissues reach a completely saturated level. The diver can stay under high pressure for dozens of days. After the operation is completed, the decompression is once and return to normal life. When divers are performing saturation diving operations, they must live in a saturated living cabin so that the body can reach complete saturation in an environment equivalent to the seabed pressure. The complete set of equipment and equipment required to transport divers for diving operations under pressure is the saturation diving system. Generally, it includes a diving bell, a deck decompression chamber, a hoisting system, and life support equipment. Among them, the deck decompression chamber refers to a device installed on a mother ship or an offshore platform for divers to pressurize, decompress, and live under high pressure during saturation diving. The deck decompression chamber is generally composed of a main cabin and a transition cabin, with a hatch in between.

[0003] Saturation diving is to create an environment and conditions that allow the inert gases dissolved in the diver's body fluids to reach a fully saturated level. Divers can stay under high pressure for dozens of days and then decompress after all tasks are completed. Therefore, the decompression time for saturation diving is generally longer. Taking saturation diving at a depth of 300 meters as an example, the decompression time is expected to be more than 11 days. During the decompression process, divers need to live in the deck decompression chamber. Therefore, the deck decompression chamber must be able to provide divers with a living environment under high pressure exposure conditions, and be equipped with an environmental control system, sanitary equipment, and equipment necessary for life.
