Description

Technical Field

[0001] The utility model relates to the technical field of diving equipment, in particular to a small diving bell used in a motorized saturation diving system. Background Art

[0002] Commercial diving is divided into air diving, mixed gas diving and saturation diving. The first two have simple equipment, but long decompression time and low operating efficiency. Saturation diving is a diving method suitable for long-term operations under deep conditions.

[0003] The principle of saturation diving: When a diver stays at a certain depth underwater or in a high-pressure environment equivalent to the ambient pressure at that depth, the neutral mixed gas (helium and nitrogen) in the breathing gas will gradually dissolve into the human tissue. If the stay time is long enough (more than 24 hours), the partial pressure of the neutral gas in the human tissue will reach a state of equilibrium with the partial pressure of the neutral gas in the breathing gas (complete saturation). In this case, no matter how long the diver stays at this depth, the neutral gas in the human tissue will not increase, and the decompression time will not increase due to the extension of the stay (diving) time. Therefore, the diving operation time is greatly extended when the decompression time remains basically unchanged. In this way, the diver can stay underwater for a long time until the underwater operation task is finally completed, and then return to the surface (normal pressure) for a one-time inspection.

[0004] Advantages of saturation diving:

[0005] (1) Greatly expanded diving depth and time:

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

[0007] (2) Greatly improved diving operation efficiency:

[0008] Saturation diving not only has advantages in operating at great depths, but also has diving operation efficiency that cannot be achieved by conventional diving.

[0009] Since saturation diving greatly expands the diving depth and increases the diving operation time, thus greatly improving the diving operation efficiency, developed countries have widely adopted saturation diving technology in deep underwater rescue and salvage operations.

[0010] In the saturation diving system, the diving bell is an important device in the system. The diving bell is a cylindrical or spherical pressure-resistant rigid body with airtight doors on the sides and bottom. It can withstand internal and external pressure. Its main function is to carry divers from the deck decompression chamber to the operating depth, and then carry them from the operating depth to the deck decompression chamber after the operation is completed.
