Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of saturation diving, and particularly relates to a mobile saturation diving system. BACKGROUND

[0002] Saturation diving is a diving mode suitable for deep water conditions and long-time operation. The basic principle is that the diver absorbs inert gas in the diving process until saturation is reached. Regardless of the length of time, the desaturation time remains constant, so saturation divers only need to perform a unified decompression process after the task is completed, thereby significantly improving the efficiency of deep-sea operations. Saturation diving is widely used in tasks such as installation and maintenance of offshore oil platforms, laying of submarine pipelines, deep-sea salvage, submarine rescue, and emergency rescue. To support diving operations in high-risk, long-time, and high-pressure environments, a saturation diving system is usually provided, including a living cabin, a diving bell, life support equipment, a gas source system, and other components. The mobile saturation diving system is a non-ship-mounted device that is usually stored in a warehouse or at a shore terminal. When performing a task, it is loaded onto a support ship by a lifting vehicle, installed on a predetermined base, and quickly assembled for use, thereby meeting the needs of deep diving operations in different scenarios.

[0003] However, the existing mobile saturation diving system still has some technical deficiencies in actual application, mainly in the following aspects: first, the system has low module integration and unclear function division, resulting in a long installation and debugging time and difficulty in meeting the requirement of rapid deployment; second, the existing gas source system generally adopts a decentralized control and gas distribution strategy, lacks a unified centralized distribution mechanism, and cannot flexibly adjust the gas distribution ratio and gas path under different operating depths, affecting the physiological safety of divers and the energy efficiency of the system; third, the diving bell completely relies on a steel cable to bear its entire weight, and is greatly affected by external disturbances such as waves and currents in adverse sea conditions, which easily causes the diving bell to shake violently, and even tilt, deflect, or hit the platform during lifting or recovery, seriously threatening the safety of divers and the stability of lifting operations; in addition, the support modules have insufficient coupling, and lack an integrated energy management mechanism, making it difficult to achieve automatic operation in high-risk environments.

[0033] The hoisting module 3 comprises a bell winch 31, a mooring winch 32, an umbilical winch 33, a mooring weight 34, a door-shaped hanger 35 and a hydraulic device 36. The bell winch 31 is used for lifting and lowering the diving bell body 21, the mooring winch 32 is used for laying or recovering a mooring line, the umbilical winch 33 is used for winding and releasing a main umbilical connected with the diving bell body 21, the mooring weight 34 is used for tensioning the mooring line and providing stability, the door-shaped hanger 35 provides space support required by the overall lifting structure of the diving bell module 2, and the hydraulic device 36 provides power for various winches and hangers.

[0034] Please refer to Figure 2The life support equipment module 4 includes a seawater heating device 41, an environmental control system outboard machine 42, a living water supply device 43, and a power distribution cabinet 44. The seawater heating device 41 heats cold seawater provided by a mother ship to a suitable temperature for heat exchange of a diver and internal temperature adjustment of a diving bell. The environmental control system outboard machine 42 cooperates with an in-cabin environmental control device to build a temperature and humidity control loop. The living water supply device 43 provides water for the diver. The power distribution cabinet 44 converts power supplied by the mother ship into power available inside the system and realizes stable power supply for each module.

[0035] Referring to Figure 3 The centralized operation control module 5 includes a living cabin control console 51, a diving bell control console 52, and an electrical control cabinet 53. The living cabin control console 51 is used to control the gas, temperature, power supply, and communication system of the living cabin module 1. The diving bell control console 52 is used to remotely monitor and control the states of the diving bell module 2. The electrical control cabinet 53 centrally manages the power supply, signal connection, and emergency control lines of each module.

[0036] Referring to Figure 6 The gas source module 6 includes a helium gas cylinder 61, an oxygen gas cylinder 62, a mixed gas cylinder 63, a compressed air cylinder 64, a liquid nitrogen Dewar 65, and a liquid oxygen Dewar 66. The helium gas cylinder 61 and the oxygen gas cylinder 62 provide main breathing gas components for the diver. The mixed gas cylinder 63 stores breathing gas mixed in proportion. The compressed air cylinder 64 is used for pressurization and pressure maintenance inside the system. The liquid nitrogen Dewar 65 and the liquid oxygen Dewar 66 are used as low-temperature gas storage units for special depth working conditions or emergency gas supply. The living cabin control console 51 and the diving bell control console 52 are used to control the gas supply of the gas source module 6 to the living cabin module 1 and the diving bell module 2. The gas supply mode can be dynamically switched based on the actual working depth and task requirements, ensuring the safety, continuity, and adaptability of the system gas supply.

[0037] Referring to Figures 4-5 The annular airbag 23 is divided into an upper airbag cavity 24 and a lower airbag cavity 25 by a partition cloth. The partition cloth divides the annular airbag 23 into two independent and sealed cavity regions. The gas inlet of the upper airbag cavity 24 is connected to the emergency gas cylinder 22 through a first gas pipeline 26. The first gas pipeline 26 is used to introduce the gas in the emergency gas cylinder 22 into the upper airbag cavity 24 under control command to provide buoyancy or adjust the attitude. The gas inlet of the lower airbag cavity 25 is communicated with the diving bell exhaust port 28 through a second gas pipeline 27. The second gas pipeline 27 makes the gas discharged from the diving bell exhaust port 28 enter the lower airbag cavity 25, so as to form auxiliary buoyancy by using the waste gas and improve the gas utilization efficiency. The emergency gas cylinder 22 is inflated by the gas source module 6. The gas in the gas source module 6 can be supplemented or pre-charged to the emergency gas cylinder 22 through a set passage, so as to ensure independent inflation capacity in an emergency.

[0038] Further, the upper air bag chamber 24 comprises a plurality of evenly arranged partition chambers 241, which are symmetrically arranged along the circumference of the ring-shaped air bag 23, so that the buoyancy adjustment is more precise and balanced. Each partition chamber 241 is in communication with the first gas pipeline 26 through an independent branch pipeline 242, which is used to introduce the gas source into different partition chambers 241 respectively, realizing partition control and independent inflation. The diving bell console 52 controls selective inflation of some of the partition chambers 241 according to the attitude information of the diving bell, which can include roll, pitch or yaw attitude deviation. By selectively injecting gas into the target position of the partition chamber 241, the overall buoyancy center is adjusted, the attitude of the diving bell body 21 is adjusted during hoisting or underwater operation, and the inclination or deflection is avoided, thereby improving the stability and control accuracy of the diving bell module 2 in a dynamic environment.

[0039] Please refer to Figure 6 In the embodiment, the helium cylinder 61 is provided with a first helium branch 611 and a second helium branch 612 on the gas discharge pipeline. The first helium branch 611 is connected to a high-pressure helium gas supply unit, which provides a source of high-purity helium gas for pressurization of the diving chamber or emergency gas replenishment. The second helium branch 612 is combined with the first oxygen branch 621 of the oxygen cylinder 62 to a automatic gas mixing device for mixing. The gas discharge pipeline of the oxygen cylinder 62 is provided with a first oxygen branch 621, a second oxygen branch 622 and a third oxygen branch 623. The first oxygen branch 621 is used to cooperate with the second helium branch 612 to generate standard helium-oxygen mixed gas. The second oxygen branch 622 can be connected to an oxygen gas supply unit, which can independently provide direct high-purity oxygen for the diver's breathing system, medical hyperbaric chamber or maintaining the stability of the oxygen concentration in the chamber, avoiding interference with the ratio sharing system of helium-oxygen mixed gas, and improving the oxygen supply accuracy and flexibility of use. The automatic gas mixing device mixes the helium and oxygen according to the preset ratio to form the target mixed gas, and connects the mixed gas to the inflation pipeline of the mixed gas cylinder 63 after increasing the pressure of the mixed gas through a gas pressure increasing device, thereby realizing automatic gas replenishment and accurate ratio of the mixed gas cylinder 63, and meeting the dynamic control requirements of the composition and pressure of breathing gas at different depths. The gas pressure increasing device is also connected to the emergency gas cylinder 22 for inflation. The delivery of the pressurized gas to the emergency gas cylinder 22 can ensure that it is in a high-pressure full state in the initial state, which is convenient for rapid release in emergency situations for buoyancy adjustment or emergency gas supply.

[0040] Further, the third oxygen branch 623, the gas discharge pipeline of the mixed gas cylinder 63, and the gas discharge pipeline of the compressed air cylinder 64 converge to the multi-element mixed gas distribution device, the third oxygen branch 623 provides pure oxygen components, the gas discharge pipeline of the mixed gas cylinder 63 outputs the prepared helium-oxygen mixed gas, and the gas discharge pipeline of the compressed air cylinder 64 provides air-based gas. The multi-element mixed gas distribution device groups and proportionally controls the three types of gas and outputs different components of breathing gas as needed. The multi-element mixed gas distribution device is connected to the multi-element gas supply unit, which serves as a dynamic output platform. The multi-element gas supply unit is connected to the habitat control console 51 and the diving bell console 52. Based on real-time operating depth data, the habitat control console 51 and the diving bell console 52 control the multi-element gas supply unit to switch the type and proportion of output gas, thereby providing compressed air, helium-oxygen mixed gas, or helium-nitrogen-oxygen mixed gas to the habitat module 1 and the diving bell module 2, meeting the breathing safety and physiological adaptation needs of divers in different diving environments. In this embodiment, the multi-element gas supply unit provides compressed air, helium-oxygen mixed gas, or helium-nitrogen-oxygen mixed gas according to the operating depth, has the ability to adapt to the physiological needs of divers in different water depth environments, effectively reduces the risk of high-pressure nervous syndrome, nitrogen narcosis, and hyperoxia toxicity, and improves the safety and efficiency of diving operations.

[0041] Further, a liquid nitrogen Dewar 65 and a liquid oxygen Dewar 66 can also be provided and connected to the multi-element gas supply unit. The liquid nitrogen Dewar 65 is used to provide a nitrogen source. When helium-nitrogen-oxygen ternary mixed gas is needed, the amount of liquid nitrogen vaporization can be controlled to accurately adjust the proportion of nitrogen. The multi-element gas supply unit generates helium-nitrogen-oxygen mixed gas suitable for a specific diving depth by mixing with the helium and oxygen flow paths. The liquid oxygen Dewar 66 is used to provide high-purity oxygen. Compared with traditional gaseous oxygen cylinders, liquid oxygen can store more oxygen in the same volume, has the advantages of small size, light weight, and long endurance, and is particularly suitable for saturation diving environments with limited space and long oxygen supply periods. In addition, liquid oxygen can provide a stable constant-temperature oxygen supply through the vaporization process, which is more accurate for adjusting the oxygen concentration in the cabin and helps to improve the reliability and gas utilization efficiency of the life support system.

[0042] In addition, a helium recovery device is also included for recovering helium from the diving gas or cabin decompression gas. The helium recovery device can effectively collect and reuse the helium-rich gas discharged during diving, especially during the decompression or snorkeling stage, as a large amount of helium is discharged with decompression or exhalation. The device can significantly reduce helium waste, improve gas source utilization efficiency, and reduce system operating costs. The helium recovery device is connected to the gas pressurization device, which is used to re-pressurize the recovered low-pressure helium to a usable pressure level, so that it can re-enter the gas source circulation system to participate in the preparation or storage of mixed gas, ensuring efficient closed-loop utilization of helium resources.

[0043] Please refer to Figure 2The seawater heating device 41 is used for heating and pressurizing seawater provided by the mother ship to provide heat seawater with required pressure level, flow rate and temperature for the diver and the seawater radiator in the bell. The seawater heating device 41 is used for constant temperature heating of the original cold seawater by the heating unit, and realizes flow rate adjustment and pressure stabilization by the built-in water pump, so as to ensure the smooth circulation of the heat seawater in the bell, maintain the internal environment temperature of the diving bell module 2 and provide heat source support for heat exchange before the diver leaves the bell, and improve the human thermal comfort and operation preparation efficiency. The power distribution cabinet 44 is used for modulating two power sources input from the main power distribution board and the reliable power distribution board of the mother ship to supply power to the hydraulic device 36, the domestic water supply device 43, the seawater heating device 41, the environmental control host and the centralized operation control module 5. The power distribution cabinet 44 has input switching and voltage stabilization functions, and ensures stable operation of the key system under the condition of power failure or voltage fluctuation by double-redundancy power supply configuration, so as to provide safe and continuous energy support for the whole saturation diving system.

[0044] The environmental control system extravehicular machine 42 adopts a cold and hot water unit, and uses 30% ethylene glycol water solution as heat medium and cold medium water. The ethylene glycol water solution has good thermal stability and anti-freezing performance, and can still maintain high-efficiency heat transfer effect in extreme marine environment. The ethylene glycol water solution forms a heat medium water loop and a cold medium water loop, and the two loops are respectively responsible for heat output and cold output. The double-loop system can realize high-precision temperature adjustment, and is used for driving the environmental control machine in the first and second saturation living cabins. The environmental control machine automatically adjusts the flow rate of the heat medium or cold medium water according to the real-time temperature and humidity in the cabin, so as to realize dynamic control of the air temperature, humidity and air quality in the cabin, and ensure the stable and comfortable environment for the diver to work and live in the saturation state for a long time.

[0045] The door type hanger 35 is a foldable hanger, the foldable structure makes it convenient to store and transport in the non-working state, and can be quickly unfolded to form a stable frame in the deployed state, providing the structure and space required for displacement support for the deployment and recovery of the diving bell module 2 and the guide cable ballast 34, and ensuring that the diving bell module 2 is vertically lowered and the guide cable is not wound or deviated through a set geometric displacement. The bell winch 31 is a main winch, which is used to undertake the main lifting task of the diving bell module 2, has high load capacity and multi-section speed control, the guide cable winch 32 is a secondary winch, which cooperates with the guide cable ballast 34 to control the guide cable tension and position, avoiding the guide cable from shaking or knotting during the operation, the diving bell main umbilical is wound on the umbilical winch 33, the umbilical winch 33 is a multi-layer winding structure, which is used to uniformly release or wind the diving bell main umbilical during deployment and recovery, and can lift the diving bell module 2 to its main lifting point to expose the water surface in the emergency working condition, ensuring that the diver can timely evacuate the underwater environment. The bell winch 31, the guide cable winch 32 and the umbilical winch 33 are all driven by the hydraulic device 36, the hydraulic drive system has high responsiveness and impact resistance, and is suitable for precise control in complex sea conditions, and ensures the reliable operation of the system in normal and abnormal states.
