Description

Technical Field

[0001] This invention relates to the field of oxygen depletion buffer tank technology, and specifically to an integrated device for a ship's gas storage buffer tank. Background Technology

[0002] Currently, in deep-sea diving operations, specialized vessels equipped with decompression chambers and microbarotrauma chambers are needed to transport divers to shallower waters. These vessels, along with oxygen decompression tanks and oxygen release buffers, form a crucial system ensuring the safety and efficiency of diving operations. The marine decompression chamber is the core equipment for safe decompression after deep-sea diving, preventing decompression sickness caused by nitrogen bubbles generated during sudden pressure changes. The marine microbarotrauma chamber assists divers in denitrification before and after diving, helping them expel excess nitrogen and further reducing the risk of decompression sickness, thus protecting the diver's health. Both decompression chambers and microbarotrauma chambers require oxygen release buffers to reduce the impact damage to equipment caused by direct oxygen output. These buffers store and buffer small amounts of oxygen for crucial gas output regulation, ensuring a stable and continuous supply of oxygen during operation. This maintains the chamber's pressure and oxygen concentration within a safe and suitable range, collectively safeguarding the health and safety of diving personnel.

[0003] The invention patent with publication number CN111442182B discloses a hydrogen storage buffer filter tank, including a buffer tank in the shape of a cylindrical tube, with an inlet and an outlet at both ends of the buffer tank, and a heat exchange shell and a filter cylinder. The heat exchange shell is sealed and fitted outside the buffer tank, and a heat exchange jacket is formed between the inner circumference of the heat exchange shell and the outer circumference of the buffer tank. A flow guiding spring is provided in the heat exchange jacket and fitted outside the buffer tank. The two ends of the flow guiding spring are respectively arranged with the inlet and outlet at both ends of the heat exchange shell. The filter cylinder is located inside the buffer tank, with one end closed and the other end connected to the inlet of the buffer tank. The filter cylinder includes an inner filter cylinder and an outer filter cylinder, with a filter element layer provided between the inner filter cylinder and the outer filter cylinder.

[0004] The buffer tank mechanism described in the aforementioned patent can also be used for oxygen release buffering in diving decompression chambers or micro-hyperbaric oxygen chambers. However, during use, when the compressed oxygen supplied by the oxygen compressor to the buffer tank contains a large amount of moisture, the oxygen encounters pressure and temperature changes upon entering the buffer tank, causing the moisture to condense into droplets. Furthermore, if the compressor or other equipment is not properly sealed or the filtration is inadequate, a small amount of lubricating oil and dust impurities may enter the oxygen flow path and subsequently enter the oxygen release buffer tank, mixing with the moisture to form waste droplets. Although some buffer tanks are equipped with filtration mechanisms to trap these waste droplets, there is a lack of online cleaning of the filtration mechanisms, and the waste droplets are of varying sizes. When a large amount of oxygen accumulates, it will automatically drip into the flow channel at the bottom of the filter mechanism. It is also difficult to clean it online, resulting in poor filtration effect and low oxygen output quality, which is not conducive to the safe decompression and recovery of divers. It is necessary to shut down the machine regularly for disassembly, cleaning and maintenance. The buffer flow channel in the buffer tank generally uses a fixed flow guide mechanism to buffer oxygen, which cannot meet the different buffering needs of divers during decompression or treatment in the decompression or micro-pressure chamber. It is difficult to accurately control the oxygen discharge pressure and flow rate over a large range. Only the regulating valve on the output valve of the buffer tank can be used for small-range output adjustment. Therefore, multiple buffer tanks with different output ranges need to be configured for use in combination. Summary of the Invention

The edge of the groove is chamfered. The filter ring also has a toothed groove on its lower inner wall that meshes with the toothed sleeve.

[0009] Furthermore, an arc-shaped sealing section is fixedly connected between the cleaning chambers, and the arc-shaped sealing section is movably and sealingly connected between the filter ring and the fixed guide hood. Both sides of the cleaning chamber are provided with slots adapted to the filtering part of the filter ring. There is a gap between the lower wall of the slot and the lower wall of the filtering part of the filter ring. The inner wall of the filter ring and the outer wall of the elastic guide ring are movably and sealingly abutted. The bottom of the inner cavity of the cleaning chamber is contracted and fixedly connected to an L-shaped drain pipe that communicates with the transparent waste liquid chamber.

[0010] Furthermore, the inner wall of the filter ring has two arc grooves, the outer wall of the elastic guide ring has a pin protrusion that engages with the arc grooves, the outer wall of the elastic guide ring is slidably connected to the inner wall of the oxygen exhaust tank, the elastic guide ring is slidably sleeved on the L-shaped drain pipe, the bottom of the elastic guide ring has an elliptical hole that matches the L-shaped drain pipe, and the elastic guide ring is elastically connected to the top buffer cover.

[0011] Furthermore, the liquid-pressing assembly includes a liquid-pressing plug slidably connected to the top of the inner cavity of the transparent waste liquid tank. The liquid-pressing plug is located above the lower port of the L-shaped drain pipe. A plurality of guide posts in a circumferential array are fixedly connected to the bottom of the inner cavity of the transparent waste liquid tank. The liquid-pressing plug is slidably sleeved on the guide posts. A plurality of through holes are opened circumferentially on the liquid-pressing plug.

[0016] The beneficial effects of this invention are as follows: This invention utilizes the principle that when oxygen is introduced into the oxygen tank and impacts the S-shaped buffer chamber, changes in oxygen pressure cause different impact forces that intermittently move the elastic guide ring downwards. This allows the cleaning component to automatically clean the moisture and impurities on the filter ring, enhancing its filtration effect and improving the quality of oxygen absorption for divers' decompression. Simultaneously, the cleaning component automatically discharges moisture and impurities into a transparent waste liquid tank to form waste liquid. The pressure component can then continuously pressurize the waste liquid online to prevent oxygen leakage, ensuring the safety and reliability of waste disposal and the continuity of oxygen extraction from the oxygen tank. This allows divers to stably absorb oxygen, ensuring their health and safety.

[0017] This invention utilizes an S-shaped buffer chamber, multiple buffer channels, and a variable resistance buffer assembly to perform multi-stage buffering of oxygen discharge, effectively improving the buffering effect and ensuring stable oxygen discharge. In conjunction with the use of a spiral tube to drive a telescopic filter membrane to change the resistance to oxygen, the buffering performance can be adjusted according to the diver's decompression needs, allowing for flexible and precise adjustment of the oxygen discharge pressure and rate over a wide range.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] Example 1, as Figures 1-9 As shown, an integrated device for a ship's gas storage buffer tank includes an oxygen venting tank 1. The upper inner cavity of the oxygen venting tank 1 is respectively provided with a fixed flow guide hood 2 and an elastic flow guide ring 3. A T-shaped support rod 13 is fixedly connected between the inner wall of the oxygen venting tank 1 and the oxygen venting valve pipe 12. The fixed flow guide hood 2 is fixedly sleeved on the T-shaped support rod 13. The top of the fixed flow guide hood 2 is tapered into a cone shape. An S-shaped buffer cavity 4 is provided between the fixed flow guide hood 2 and the elastic flow guide ring 3. A filter ring 51 and a cleaning component are provided in the middle of the S-shaped buffer cavity 4. A transparent waste liquid tank 6 is fixedly sleeved around the oxygen venting tank 1. A drain valve pipe 61 is fixedly inserted into the bottom of the transparent waste liquid tank 6. A pressure component for separately removing waste liquid is provided on the top of the transparent waste liquid tank 6. The lower inner wall of the oxygen exhaust tank 1 is fixedly connected with several buffer covers 7 in a linear array. The middle of the buffer cover 7 is rotatably connected to a volute tube 8. Several through slots 81 are opened on the volute tube 8. A flow guide platform 82 is provided between the buffer covers 7 and sleeved on the volute tube 8. There is a buffer cavity 83 between the flow guide platform 82 and the buffer cover 7 that connects with two adjacent through slots 81. A variable resistance buffer assembly is movably connected to the top of the flow guide platform 82. A telescopic filter membrane 86 is provided on the top of the variable resistance buffer assembly.

[0022] The top of the oxygen exhaust tank 1 is contracted to form an inlet 11, and the bottom of the oxygen exhaust tank 1 is fixedly connected to an oxygen exhaust valve pipe 12. The top of the volute tube 8 is slidably and sealed to the bottom of the elastic guide ring 3, and the bottom of the volute tube 8 is rotatably and sealed to the oxygen exhaust valve pipe 12.

[0023] In use, the inlet 11 of the oxygen tank 1 is connected to the output end of the oxygen compressor on the ship. After the pressurized oxygen is input through the inlet 11, it is diverted and buffered by the conical contraction end at the top of the fixed guide hood 2. The oxygen automatically enters the S-shaped buffer chamber 4 for further buffering and is output from the middle of the elastic guide ring 3 into the volute tube 8 and flows downward. The oxygen then impacts the telescopic filter membrane 86 and is further buffered by the variable resistance buffer component. Some oxygen continues to flow downward after being buffered by the telescopic filter membrane 86, while the oxygen that does not pass through the telescopic filter membrane 86 in time is dispersed to the surroundings and enters the buffer channel 83 through the through groove 81 for buffering. It then enters the volute tube 8 again from the bottom of the buffer channel 83 through the lower through groove 81, where it converges with the oxygen that has passed through the telescopic filter membrane 86 and flows downward together. Subsequently, multiple identical buffer channels 83, telescopic filter membranes 86 and variable resistance buffer components are used to perform multi-stage buffering of the oxygen. The buffered oxygen output is stable and is output to the outside through the oxygen exhaust valve pipe 12 at the bottom of the volute tube 8. During oxygen buffering, the oxygen introduced into the S-shaped buffer chamber 4 experiences varying impacts due to changes in input pressure. This causes the elastic guide ring 3 to intermittently move downwards, thereby driving the cleaning component to automatically clean the moisture and impurities on the filter ring 51. This enhances the filtration effect of the filter ring 51 and improves the oxygen absorption quality for divers' decompression. Simultaneously, the cleaning component automatically discharges the moisture and impurities into the transparent waste liquid tank 6, forming waste liquid. The pressure liquid component allows for online cleaning without stopping the machine, isolating the oxygen and preventing oxygen leakage. This ensures the safety and reliability of waste cleaning and the continuity of oxygen discharge from the oxygen tank 1, enabling divers to stably absorb oxygen and ensuring their health and safety. Furthermore, under different decompression conditions, controlling the rotation of the worm gear tube 8 causes the telescopic filter membrane 86 to change its shape and alter its resistance to oxygen. This allows for flexible and precise adjustment of the oxygen discharge pressure and rate over a wide range, according to the diver's decompression needs.

[0024] In embodiment two, based on the above embodiment, the cleaning component includes a cleaning chamber 5 fixedly connected to the inner wall of the fixed guide shroud 2. The cleaning chambers 5 are arranged in a circumferential array and the number is set to four. The filter ring 51 is rotatably and sealingly connected between the cleaning chambers 5. The inner wall of the cleaning chamber 5 is concave and a toothed sleeve 55 is rotatably connected in the middle. An elastic cleaning roller 56 is slidably engaged in the toothed sleeve 55. The elastic cleaning roller 56 is provided with bristles on its periphery. An elliptical groove 57 is opened on the side wall of the toothed sleeve 55. An L-shaped impact post 58 that can abut against the filter ring 51 is slidably engaged in the inner wall of the middle of the cleaning chamber 5. The L-shaped impact post 58 is movably engaged with the elliptical groove 57. The inner circumference of the outer periphery of the filter ring 51 is provided with a groove 53 that movably abuts against the elastic cleaning roller 56. The edge of the groove 53 is chamfered. The lower circumference of the outer periphery of the filter ring 51 is provided with a toothed groove 54 that meshes with the toothed sleeve 55.

[0025] The S-shaped buffer chamber 4 is used to guide and buffer oxygen. When the oxygen flows to the middle of the S-shaped buffer chamber 4, it continues to flow from the area between the cleaning chambers 5 and is filtered through the filter ring 51. Moisture, oil, or dust impurities are trapped on the lower wall of the filter ring 51. When the filter ring 51 rotates and carries the filter material adsorbed or attached to the lower wall of the filter ring 51 under the impact of airflow into the cleaning chamber 5, part of the filter ring 51 in the cleaning chamber 5 is destroyed by the impact of airflow, and some filter material falls off by gravity. As the filter ring 51 drives the toothed groove 54, the toothed sleeve 55 rotates. The toothed sleeve 55 then drives the elastic cleaning roller 56 to brush off the remaining filter material with the bristles. During this process, the elastic cleaning roller 56 drives the bristles. The rotation direction is opposite to that of the filter ring 51, allowing the bristles to brush off the filtered material, resulting in a better cleaning effect. Simultaneously, different grooves 53 sequentially contact the elastic cleaning roller 56 as the filter ring 51 rotates. The elastic cleaning roller 56 oscillates continuously under its own elastic force while cleaning the filtered material, further enhancing the cleaning effect. This, combined with the toothed sleeve 55 driving the elliptical groove 57 to rotate synchronously, and the L-shaped impact column 58 intermittently impacts and vibrates the filter portion of the filter ring 51 in the cleaning chamber 5 from the center, assisting in the removal of filtered material and preventing the vibration force from propagating too far and causing filtered material outside the cleaning chamber 5 to fall off. This further enhances the cleaning effect, ensuring the filtration efficiency of the filter ring 51 and improving the oxygen output quality.

[0026] In Example 3, based on the above examples, an arc-shaped sealing section is fixedly connected between the cleaning chambers 5. The arc-shaped sealing section is movably and sealingly connected between the filter ring 51 and the fixed guide hood 2. Both sides of the cleaning chamber 5 are provided with slots that are adapted to the filtering part of the filter ring 51. There is a gap between the lower wall of the slot and the lower wall of the filtering part of the filter ring 51. The inner wall of the filter ring 51 is movably and sealingly abutted against the outer wall of the elastic guide ring 3. The bottom of the inner cavity of the cleaning chamber 5 is contracted and fixedly connected to an L-shaped drain pipe 59 that communicates with the transparent waste liquid chamber 6.

[0027] This design ensures that when oxygen is filtered using filter ring 51, moisture, oil, or dust impurities will not enter the subsequent buffer area through the gaps on the inner and outer sides of filter ring 51, nor will they be directly output, affecting the quality of oxygen output. At the same time, the gap between the lower wall of the slot and filter ring 51 ensures that the filter part of filter ring 51 carries the filtered material to the cleaning chamber 5 stably, avoiding scraping and falling off, which would affect the cleaning of the filtered material. The design of the L-shaped drain pipe 59, which is connected to the bottom of the inner cavity of the cleaning chamber 5, facilitates the collection of filter waste liquid, which is mainly composed of water, and discharges it into the transparent waste liquid chamber 6 through the L-shaped drain pipe 59.

[0028] In Example 4, based on the above examples, two arc grooves 52 are formed on the inner circumference of the filter ring 51, and a pin protrusion 31 is provided on the outer wall of the elastic guide ring 3 to be movably engaged with the arc grooves 52. The outer wall of the elastic guide ring 3 is slidably connected to the inner wall of the oxygen exhaust tank 1. The elastic guide ring 3 is slidably sleeved on the L-shaped drain pipe 59. The bottom of the elastic guide ring 3 has an elliptical hole that matches the L-shaped drain pipe 59. The elastic guide ring 3 is elastically connected to the top buffer cover 7.

[0029] With this design, when the elastic guide ring 3 moves downward under the impact of oxygen initially entering the oxygen tank 1, the sealed space between the elastic guide ring 3 and the top buffer cover 7 is compressed and gas can be discharged outward through the elliptical hole, which facilitates the stable downward movement of the elastic guide ring 3. Furthermore, when the pressure fluctuation of the input oxygen decreases, the elastic guide ring 3 will also reset under its own elastic force, thereby driving the pin protrusion 31 to move up and down, squeezing the arc groove 52, thereby driving the filter ring 51 to rotate, and using the cleaning component to achieve online cleaning of the filter ring 51.

[0030] In Example 5, based on the above examples, the liquid-pressing assembly includes a liquid-pressing plug 63 slidably connected to the top of the inner cavity of the transparent waste liquid tank 6. The liquid-pressing plug 63 is located above the lower port of the L-shaped drain pipe 59. A plurality of guide posts 62 in a circumferential array are fixedly connected to the bottom of the inner cavity of the transparent waste liquid tank 6. The liquid-pressing plug 63 is slidably sleeved on the guide posts 62. A plurality of through holes 64 are opened on the circumference of the liquid-pressing plug 63. A valve ring 65 is rotatably and sealingly connected to the lower wall of the liquid-pressing plug 63. A curved groove 66 that is misaligned with the through holes 64 is opened on the valve ring 65. The guide posts 62 are located in the middle of the curved groove 66. A sealing ring 67 is rotatably and sealingly connected to the upper wall of the inner cavity of the transparent waste liquid tank 6. An elastic adjustment ring 68 is slidably inserted into the sealing ring 67. The bottom insertion part of the elastic adjustment ring 68 is rod-shaped and passes through the through holes 64 and is fixedly connected to the valve ring 65.

[0031] Initially, the elastic adjustment ring 68 is compressed and tends to move upward. Under tension, the pressure plug 63 squeezes the sealing ring 67, and the valve ring 65 remains relatively fixed with the pressure plug 63 under tension. When a large amount of waste liquid is observed to be collected through the transparent waste liquid tank 6, the elastic adjustment ring 68 is rotated to drive the valve ring 65 so that the curved groove 66 aligns with the through hole 64, and the air pressure above and below the pressure plug 63 is balanced. Pressing the elastic adjustment ring 68 causes the bottom of the pressure plug 63 to move down to the waste liquid surface, thus squeezing the oxygen in the transparent waste liquid tank 6 above the valve ring 65. Controlling the elastic adjustment ring 68 to rotate in the opposite direction to reset and drive the valve ring 65 to seal the through hole 64, opening the drain valve pipe 61, and controlling the elastic adjustment ring 68 to move down again, thereby isolating oxygen and driving the valve ring 65 to discharge the waste liquid online without stopping the machine for cleaning. Then, the reverse control is used to restore the pressure assembly.

[0032] In Example 6, based on the above examples, the buffer channel 83 is located around the flow guide platform 82. The top of the buffer channel 83 is inclined downward, the middle is vertical, and the bottom is S-shaped. The bottom of the buffer channel 83 is inclined downward towards the end of the through groove 81.

[0033] This design allows for the use of different configurations within the buffer cavity 83 to change the direction of oxygen flow, thereby consuming oxygen impact energy and greatly improving the buffering performance of oxygen. At the same time, since the top of the buffer cavity 83 is inclined downwards and the bottom is inclined downwards towards the end of the through groove 81, it is easy to ensure the smoothness of oxygen dispersion and convergence, avoid oxygen flow field turbulence, and improve the stability of buffering.

[0034] In embodiment seven, based on the above embodiments, the variable resistance buffer assembly includes an elastic support 84 that is slidably engaged in the through groove 81. The center of the elastic support 84 is rotatably connected to a rotating sleeve 85 that is slidably engaged in the T-shaped support rod 13 via a connecting rib. A telescopic filter membrane 86 is fixedly connected to the periphery of the rotating sleeve 85. The telescopic filter membrane 86 is twisted and its edge is inclined downward.

[0035] The bottom of the oxygen exhaust tank 1 is rotatably sealed with a worm gear rod 14 that meshes with the worm gear tube 8. The worm gear rod 14 is driven by a motor installed on the front wall of the oxygen exhaust tank 1.

[0036] The downward-sloping edge design of the telescopic filter membrane 86 facilitates the automatic diversion of oxygen flow to the buffer cavity 83 as it flows downward to the upper surface of the membrane, preventing turbulence. When the telescopic filter membrane 86 is impacted by oxygen, the elastic support tube 84 is simultaneously compressed downward, thus buffering the impact force. When it is necessary to adjust the oxygen output pressure and rate, the worm gear 14 is rotated by the motor to adjust the forward or reverse deflection of the worm gear tube 8. The elastic support tube 84 is then simultaneously deflected forward or reverse, thereby intensifying the torsion or expansion of the telescopic filter membrane 86. The pores on the membrane 86 are correspondingly compressed, contracted, or expanded, thus changing the resistance to oxygen and altering the buffering performance, allowing for flexible and precise adjustment of oxygen discharge over a wide range.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
