Description

Technical Field

[0001] The invention relates to a fresh water supply system for a deep-depth saturation diving decompression chamber, belonging to the technical field of water supply systems for diving decompression chambers. Background Art

[0002] The saturation diving system consists of equipment such as a living cabin and a diving bell. The general process of saturation diving is: before the saturation diving operation begins, the diver lives in the living cabin, and pressurizes the diver's body according to the prescribed procedures so that the inert gas reaches saturation at the predetermined operating depth. When diving operations are required, the diver enters the diving bell of the same pressure from the living cabin, and then the diving bell carrying the diver is winched to the seabed diving operation site. The diver puts on a diving suit and swims out of the diving bell to carry out operations in the sea. After completing the seabed patrol operation, the diver returns to the diving bell, and then the diving bell is recovered to the mother ship through the diving bell hoisting system, and the diver returns to the living cabin to live and rest.

[0003] The living chamber is an important living place for divers. Divers can live in it for dozens of days. During this period, divers need a lot of fresh water for daily activities such as showering and washing. The living chamber needs to maintain a high environmental pressure. In this case, how to provide divers with safe, timely and suitable daily fresh water supply in the living chamber is a major problem. In particular, when conducting deep saturation diving, such as 1000 meters, the pressure in the living chamber can reach 10MPa, and the continuous supply of daily fresh water becomes difficult to handle. At present, there is no fresh water supply system for saturation diving living chambers that can work at great depths in the world, making the safe, continuous and suitable temperature supply of fresh water in saturation diving living chambers a thorny issue. Summary of the invention

[0004] The invention provides a fresh water supply system for a deep saturation diving decompression chamber in order to provide fresh water for life needs for a deep saturation diving decompression chamber.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: a fresh water supply system for a deep-depth saturation diving decompression chamber, the deep-depth saturation diving decompression chamber includes a living chamber, the living chamber is divided into a main chamber and an auxiliary chamber; the special feature is that it also includes a water storage tank, a mixer and a distributor; a thermostat is installed at the inlet end of the mixer, the thermostat is connected to the hot water pipe and the cold water pipe at the same time, the hot water pipe is provided with a hot water valve, the cold water pipe is provided with a cold water valve, the thermostat obtains fresh water suitable for divers by adjusting the opening of its internal cold and hot water interfaces, the temperature adjustment can be adjusted on the system console, and the thermostat is located before the system is pressurized; the water storage tank is connected to the mixer through a pipeline, and the water storage tank is used to temporarily store fresh water; the mixer and A pumping pipeline is arranged between the distributors, the high-pressure pump group is installed on the pumping pipeline, a check valve is arranged on the pipeline from the high-pressure pump group to the distributor to prevent fresh water from flowing back to the high-pressure pump group, the mixer and the distributor are also provided with a connected return pipeline, and a release valve is arranged on the return pipeline, the system fresh water is pressurized by the high-pressure pump group, and then transported to the distributor, and then transmitted to the interface required by the diver in the living cabin through pressure release, without the need to use an additional pressure water storage tank; the distributor is provided with two water supply pipelines respectively connected to the main cabin and the auxiliary cabin, each water supply pipeline is provided with a check valve to prevent fresh water from flowing back to the distributor, and each water supply pipeline is provided with an outside cabin valve and an inside cabin valve located outside the living cabin.

[0006] When the living chamber of the saturation submersible is in any state of pressurization, stable pressure or decompression, the divers in the living chamber can obtain the required fresh water by opening / closing the valve inside the chamber (people outside the living chamber can open / close the valve outside the chamber) to automatically start / stop the system; the mixer and distributor are both made of stainless steel.

[0007] On the basis of the above technical solution, in order to achieve the convenience of use and the stability of the equipment, the present invention can also make the following improvements to the above technical solution:

[0008] Furthermore, a safety valve is provided on the water storage tank.

[0009] Furthermore, a thermometer is installed on the mixer.

[0010] Furthermore, the distributor is equipped with a pressure sensor, a pressure gauge and a temperature sensor. The pressure sensor is used to detect the system pressure and is displayed on the control panel. At the same time, the distributor is equipped with a pressure gauge with a local display.

[0011] Furthermore, a pressure switch is installed on the water supply pipe from the distributor to the living cabin, and the pressure switch is located between the distributor and the check valve on the water supply pipe. The pressure switch is closed when the pressure in the living cabin is greater than the system pressure, and is opened when the pressure in the living cabin is less than the system pressure.

[0012] Furthermore, a stop valve A and a check valve A are installed on the pipeline from the high-pressure pump group to the distributor. The check valve A can prevent the impact of excessive pressure in the living cabin on the system and protect system components and instruments.

[0013] Furthermore, a spare high-pressure pump set is also provided.

[0014] The advantages of the present invention are: the present invention has a reasonable structure and is easy to operate, and the fresh water required by divers in the living cabin can be obtained by setting a mixed temperature controller for the designed cold water pipeline and hot water pipeline.
