Description

Technical Field

[0001] This application relates to the technical field of deep - sea manned equipment, and particularly to an oxygen supply device and operation method for deep - sea manned vehicles. Background Art

[0002] With the rapid development of deep - sea manned submersible technology, there has emerged a technical requirement for maintaining long - term operations of submariners in a sealed cabin. This technology constructs a personnel activity space through a deep - sea pressure - resistant structure, which features the integration of high - precision navigation equipment, life support systems, and emergency devices to achieve deep - sea operation capabilities, thus giving rise to a replenishment method for fixed oxygen storage devices.

[0003] In related technologies, the mainstream solution is to adopt a non - renewable high - pressure oxygen supply system. Medical oxygen is pre - filled on shore - based facilities or support ships and connected to the fixed oxygen storage device of the vehicle through pipelines or quick - connectors; when the oxygen concentration in the cabin drops to a preset threshold, replenishment is completed by directly injecting from an external gas source.

[0004] However, the above - mentioned replenishment method still has technical problems:

[0005] Firstly, the space in the manned cabin of deep - sea vehicles is compact, and the proportion of precision instruments is high, making it difficult to implement the traditional detachable gas cylinder replacement scheme; secondly, during the direct oxygen filling process, the oxygen concentration in the cabin may instantaneously exceed the safety threshold, and the response delay of the existing monitoring system poses a major safety hazard; finally, the pressure fluctuations and temperature changes in the deep - sea environment lead to unstable gas source pressure, further increasing the control difficulty during the replenishment process.

[0006] These above - mentioned technical problems jointly restrict the safety and operation duration of deep - sea manned operations, becoming a technical bottleneck that urgently needs to be broken through in this field. Summary of the Invention

[0007] Based on this, it is necessary to provide an oxygen supply device and operation method for deep - sea manned vehicles to address the above - mentioned problems. By using the technology of driving exhaust gas reuse, without increasing the additional energy burden, it meets the cooling requirements of high - pressure oxygen during the oxygen replenishment process, improves energy utilization efficiency, and at the same time reduces the adverse effects caused by the short - term sharp rise in oxygen temperature.

[0008] An oxygen supply device for a deep - sea manned vehicle includes:

[0009] An air compressor module for providing driving gas;

[0010] A pneumatic booster pump connected to the air compressor module through a driving gas metal hose for boosting low - pressure oxygen into high - pressure oxygen;

[0011] A cooler, connected to the output end of the pneumatic booster pump, uses the waste driving gas to cool the high-pressure oxygen after boosting;

[0012] A mobile oxygen replenishment console, integrated with an oxygen source interface, a high-pressure oxygen output interface, a flow regulating valve, a safety valve, an oxygen pressure gauge at the output end, and an oxygen source pressure gauge;

[0013] The mobile oxygen replenishment console is connected to an external oxygen source through an oxygen source metal hose and is connected to the oxygen storage device to be replenished through a replenishment oxygen metal hose.

[0014] In one embodiment, the mobile oxygen replenishment console is further configured with a mechanical pressure switch. The mechanical pressure switch drives the opening and closing of the gas path by sensing the deformation of the pressure spring, and automatically shuts down the pneumatic booster pump when the oxygen pressure at the output end reaches a preset threshold.

[0015] In one embodiment, the cooling medium of the cooler is the low-temperature waste driving gas after the pneumatic booster pump does work, and the cooler is connected to the waste gas output end of the pneumatic booster pump.

[0016] In one embodiment, the mobile oxygen replenishment console further includes a manual unloading valve for manually relieving pressure when the oxygen pressure is abnormal.

[0017] In one embodiment, the mobile oxygen replenishment console is integrated with universal wheels and a hose storage box for the movement of the device and the storage of hoses.

[0018] In one embodiment, the pneumatic booster pump monitors the driving gas pressure and the remaining pressure of the oxygen source in real time through a driving gas pressure gauge and an oxygen source pressure gauge, and adjusts the oxygen replenishment rate through a flow regulating valve.

[0019] On the other hand, the present application also provides an oxygen replenishment operation method for a deep-sea manned vehicle. The oxygen replenishment operation is carried out through the above-mentioned oxygen replenishment device for a deep-sea manned vehicle, including the following steps:

[0020] Connect the mobile oxygen replenishment console to the air compressor module through a driving gas metal hose, connect it to an external oxygen source through an oxygen source metal hose, and connect it to the oxygen storage device to be replenished through a replenishment oxygen metal hose;

[0021] Start the air compressor module to provide driving gas to the pneumatic booster pump, and drive the piston of the booster pump to reciprocate to boost oxygen;

[0022] Use the cooler to cool the high-pressure oxygen after boosting;

[0023] Adjust the oxygen replenishment rate through the flow regulating valve of the mobile oxygen replenishment console, and monitor the oxygen pressure at the output end and the remaining pressure of the oxygen source in real time.

[0024] In one of the embodiments, the invention further comprises: when the oxygen pressure at the output end reaches a preset threshold, the pneumatic booster pump is automatically shut down by a mechanical pressure switch;

[0025] If oxygen leakage or abnormal pressure is detected, immediately open the manual unloading valve to release the pressure, and close the air compressor module and the oxygen source shut-off valve.

[0026] In one embodiment, the materials and lengths of the driving gas metal hose, the oxygen source metal hose and the oxygen supply metal hose are parameter-matched according to the operating distance, the gas source pressure and the oxygen storage pressure.

[0027] In one embodiment, the cooler is cooled by exhaust gas from a pneumatic booster pump, without the need for an additional refrigeration device.

[0028] The above-mentioned oxygen supply device and operating method for deep-sea manned vehicles reuses the driving exhaust gas and is highly efficient and energy-saving: the low-temperature driving gas exhaust gas after the pneumatic booster pump works is introduced into the cooler and used as a cooling medium to cool the high-temperature and high-pressure oxygen after the boosting. There is no need for additional refrigeration equipment, which significantly reduces energy consumption and avoids safety hazards caused by a sudden increase in oxygen temperature.

[0029] This application also has the following advantages:

[0030] (1) The mobile oxygen supply console in this application integrates an oxygen source interface, a high-pressure output interface, a flow control valve, a safety valve, a pressure gauge and a mechanical pressure switch. The bottom is equipped with universal wheels and a hose storage box. It can be quickly moved on the shore or in the cabin of the mother ship to meet the long-distance supply needs of complex deep-sea scenes;

[0031] (2) The present application has a specific multiple safety redundancy design. The mechanical pressure switch drives the opening and closing of the gas circuit through spring deformation, and automatically shuts down the booster pump when the output pressure reaches the threshold to avoid the risk of overpressure; the safety valve and the manual unloading valve have a double insurance design. The safety valve automatically releases pressure, and the manual unloading valve supports emergency discharge, effectively controlling the abnormal oxygen concentration in the cabin; in addition, the present application has real-time pressure monitoring, and the driving gas pressure gauge, oxygen source pressure gauge and output end pressure gauge provide real-time feedback parameters, and the oxygen supplementation rate is accurately controlled in combination with the flow control valve;

[0032] (3) The pneumatic boosting and cooling of the present application are synergistically optimized. The pneumatic booster pump uses the driving gas provided by the air compressor to achieve efficient boosting of low-pressure oxygen, and the cooler simultaneously uses the exhaust gas for cooling, forming a closed-loop energy utilization system to improve overall energy efficiency;

[0033] (4) When leakage or abnormal pressure is detected, the present application can immediately cut off the gas line and release the pressure through the manual unloading valve, and combine with the oxygen source shut-off valve to quickly isolate the fault and maximize the safety of the manned cabin.

[0074] When abnormal pressure or leakage is detected, immediately open the manual unloading valve 20 to release oxygen, and close the air compressor module 1 and the oxygen source stop valve 8;

[0075] The safety valve 13 automatically opens under overpressure, forming redundant protection with the manual unloading valve 20.

[0076] End of operation:

[0078] Finally, move the control console 15 to the storage location through the universal wheels 24.

[0079] This application uses the waste gas of the pneumatic booster pump 14 to cool the high-pressure oxygen, eliminating the need for additional refrigeration equipment and reducing energy consumption; at the same time, the mobile oxygen supply control console 15 integrates universal wheels 24 and a hose storage box 22, adapting to long-distance operations in complex deep-sea scenarios; on the other hand, the mechanical pressure switch 21, the safety valve 13, and the manual unloading valve 20 work together to ensure operation safety; the oxygen supply rate and pressure are precisely regulated by the flow control valve 10 in cooperation with the drive gas pressure gauge 5, the oxygen source pressure gauge 9, and the output end oxygen pressure gauge 12.
