Description

Technical Field

[0001] The utility model relates to the technical field of diving control panels, and particularly relates to a helium-oxygen mixture diving control panel. Background Technique

[0002] Helium-oxygen mixture diving refers to a diving method that uses artificially prepared helium-oxygen mixture as the breathing gas. In a deep-sea environment, the water pressure will increase significantly. If a diver still breathes ordinary air (the main components are nitrogen and oxygen), nitrogen may gradually dissolve in the blood, causing nitrogen narcosis symptoms. Helium is almost insoluble in water under high-pressure environments and is not easily soluble in the blood when inhaled into the lungs, thus avoiding the "anesthetic" effect and effectively preventing the phenomenon of "nitrogen intoxication".

[0003] Gas supply problems and abnormal mixture ratios are extremely dangerous situations during diving. Therefore, during helium-oxygen mixture diving, the control of the helium-oxygen mixture is very important. Currently, the redundancy design of the diving control system is not sufficient, which is not conducive to ensuring the underwater safety of divers. Therefore, those skilled in the art have provided a helium-oxygen mixture diving control panel to solve the problems raised in the above background technique. Content of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to the attached Figures 1 to 5 As shown, a helium-oxygen mixture diving control panel in an embodiment of the present utility model includes a first gas supply module 1, a second gas supply module 2, a third gas supply module 3, a fourth gas supply module 4, and three gas transmission modules 5. The first gas supply module 1, the third gas supply module 3, and the fourth gas supply module 4 all include two gas supply pipelines, and a switching valve 8 is connected between the two gas supply pipelines. Among them, the first gas supply module 1, the third gas supply module 3, and the fourth gas supply module 4 are connected to high-pressure mixed gas to supply high-pressure helium-oxygen mixture, and the second gas supply module 2 is connected to medium-pressure air. The three gas transmission modules 5 provided are respectively used to supply gas to three divers. Among them, the first gas supply module 1, the third gas supply module 3, and the fourth gas supply module 4 all adopt a dual gas supply pipeline design and can be switched through the switching valve 8. After a problem occurs in one gas supply pipeline, it can be quickly switched to the other pipeline to ensure the safe progress of diving. At the same time, the design of the dual gas supply pipeline also facilitates quickly adjusting the composition of the mixed gas according to the actual situation to meet the diving requirements at different depths. For example, a mixed gas with a higher oxygen content can be used at a shallower depth, and a mixed gas with a higher helium content can be switched to during deep diving to prevent the problem of nitrogen narcosis.

[0028] The gas supply pipelines of the first gas supply module 1 and the third gas supply module 3 are both connected with three-way output ports. The output ports of the first gas supply module 1 are respectively HP1, HP1 1 , HP1 11 , HP2, HP2 1 , HP2 11 , and the output ports of the third gas supply module 3 are respectively HP3, HP3 1 , HP3 11 , HP4, HP4 1 , HP4 11 . The two gas supply pipelines of the fourth gas supply module 4 share an output port HP5 / 6.

[0029] The gas transmission module 5 includes a buffer tank 18, and the buffer tank 18 is connected with a plurality of input valves 19. The setting of the buffer tank can reduce the non-uniformity of the gas flow rate in the pipeline and avoid excessive pressure fluctuations.

[0030] The second gas supply module 2 has two output ports MP and MP 1, the output ports connected to the input valves 19 of the three gas transmission modules 5 are HP1, HP2, HP3, HP4, MP, MP 1 , HP1 1 , HP2 1 , HP3 1 , HP4 1 , HP1 11 , HP2 11 , HP3 11 , HP4 11 , HP5 / 6. Each gas transmission module can supply gas using other gas supply modules as the gas source, increasing the redundancy of the system. Even if a certain channel fails, there are still multiple channels available for use to ensure the safety of the divers.

[0031] The second gas supply module 2 includes a medium-pressure gas source stop valve 14, a medium-pressure gas source pressure gauge 15, a medium-pressure pressure regulating valve 16, a medium-pressure pressure regulating gauge 17, an output valve 11, a safety valve 12, and a check valve 13 connected in sequence. The check valve 13 is connected to the output ports MP, MP 1 connect.

[0032] The gas supply pipelines of the first gas supply module 1, the third gas supply module 3, and the fourth gas supply module 4 all include a high-pressure gas source stop valve 6, a high-pressure gas source pressure gauge 7, a high-pressure pressure regulating valve 9, a high-pressure pressure regulating gauge 10, an output valve 11, a safety valve 12, and a check valve 13 connected in sequence. The switching valve 8 is connected between the input ends of the two high-pressure pressure regulating valves 9.

[0033] The gas transmission module 5 further includes an oxygen detector 21, a gas supply valve 22, and a depth gauge 25. A sampling valve 20 is connected between the oxygen detector 21 and the buffer tank 18. The output end of the gas supply valve 22 is connected to a gas supply pressure gauge 23. A depth measuring valve 24 is connected between the depth gauge 25 and the buffer tank 18. Open the sampling valve 20 to use the oxygen detector 21 to detect the oxygen content in the buffer tank 18. The provided gas supply valve 22 is used to control the gas supply pressure, and the provided depth measuring valve 24 is used to monitor the diver's depth.

[0034] Working principle: During use, the three gas transmission modules 5 supply gas through the HP1, HP3, and HP5 / 6 ports of the first gas supply module 1, the third gas supply module 3, and the fourth gas supply module 4 as the first choice. Among them, the two gas transmission modules 5 connected to the first gas supply module 1 and the third gas supply module 3 are used to supply underwater operation divers, and the fourth gas supply module 4 is used to supply standby divers on the water surface. After a problem occurs in a certain gas supply pipeline of the gas supply module, the gas supply port can be switched by opening the corresponding input valve 19, or the gas source can be switched by the switching valve 8 to cope with various unexpected situations. In addition, the gas transmission module 5 can also supply gas using other gas supply modules. When its own first-choice gas supply module cannot be used, there are still multiple channels available for use to ensure the safety of the divers.

[0035] The above has described in detail an embodiment of the present utility model. However, the above content is only a preferred embodiment of the present utility model and cannot be considered as limiting the scope of implementation of the present utility model. All equivalent changes and improvements made in accordance with the scope of application of the present utility model shall still fall within the scope covered by the patent of the present utility model.
