Description

Technical Field

[0001] The present invention relates to the technical field of marine pneumatic equipment, and in particular to a water-gas separation device for a submerged buoy pneumatic buoyancy adjustment system. Background Art

[0002] Pneumatic systems are widely used in fields such as offshore platforms and underwater robots. Using air as a medium, pneumatic systems are environmentally friendly and require no complex components, enabling long-term stable operation. Furthermore, air is naturally fireproof and explosion-proof, avoiding potential safety hazards associated with other systems. Furthermore, pneumatic systems offer low maintenance costs, fast response times, and the ability to quickly adapt to marine operational needs. However, the marine environment is less stable than the terrestrial environment, and when extracting external air, seawater is inevitably inhaled. Once seawater enters the air system of mechanical equipment, it can cause corrosion to internal components, block the airway, and other safety issues. Therefore, exploring effective water-gas separation and filtration technologies is crucial to ensuring the reliable operation of marine machinery and equipment. Summary of the Invention

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0026] Example 1: Figures 1 to 2 As shown, a preferred embodiment of the present invention provides a water-gas separation device for a submersible buoyancy regulating system, the device comprising a cylindrical shell 1, a cylindrical cavity being provided in the shell 1, and the axis of the cavity being arranged in the up-down direction.

[0027] A baffle 2 that matches the inner diameter of the cavity is fixedly installed in the cavity. The baffle 2 is arranged in an inclined shape with the left side higher and the right side lower. The distance between the center of the baffle 2 and the top of the cavity is approximately one-third of the overall height of the cavity. At this point, the baffle 2 divides the cavity into an upper cavity and a lower cavity that are not connected to each other.

[0028] A filter 3 is provided within the upper chamber, dividing it into a left chamber 4 and a right chamber 5. The filter 3 is designed to remove impurities and dust from the air as it passes from the left chamber 4 to the right chamber 5. The filter 3 is preferably positioned as close to the right as possible. Since the baffle 2 is tilted, this placement increases the filter area and improves the filtering effect.

[0029] The lower chamber is equipped with a metal mesh pad 6, located roughly in the center of the lower chamber, dividing it into an upper chamber 7 and a lower chamber 8. Baffle 2 is equipped with an inner tube 9, coaxially arranged with the cylindrical cavity. Inner tube 9 extends toward the lower chamber, through metal mesh pad 6, and into lower chamber 8. The lower end of inner tube 9 is spaced from the bottom of lower chamber 8 and roughly located in the center of lower chamber 8, connecting left chamber 4 and lower chamber 8 through inner tube 9.

[0030] Furthermore, a metal mesh 10 is provided at the lower end of the inner tube 9 .

[0031] An air intake pipe 11 is provided on the left side of the shell 1 and is connected to the upper chamber 7. Specifically, the air intake pipe 11 is close to the highest point on the left side of the baffle 2, and the air intake direction is set along the tangent direction of the cylindrical cavity.

[0032] An air outlet pipe 12 is provided on the right side of the shell 1, and the air outlet pipe 12 is connected to the right chamber 5. Specifically, the inner port of the air outlet pipe 12 is located at the top of the right chamber 5. Its purpose is to prevent water droplets from entering the air outlet pipe 12 once there are water droplets in the right chamber 5.

[0033] An air venting pipe 13 is provided on the top of the housing 1 , and the air venting pipe 13 is communicated with the left chamber 4 . The air venting pipe 13 is coaxially arranged with the cylindrical cavity.

[0034] An exhaust pipe 14 is provided at the bottom of the housing 1 and communicates with the lower chamber 8. The exhaust pipe 14 is coaxially arranged with the cylindrical cavity. The inner wall of the bottom of the lower chamber 14 is funnel-shaped, which facilitates the collection of water droplets and also facilitates the discharge of water droplets through the exhaust pipe 14.

[0035] An intake control valve is provided on the intake pipe 11. The intake control valve includes a first one-way valve 15. The first one-way valve 15 conducts one-way flow from outside to inside.

[0036] An outlet control valve is installed on the outlet pipe 12. The valve includes a pneumatic normally-open external control valve 16 and a second one-way valve 17. The external control air path of the pneumatic normally-open external control valve 16 is connected to the bleed pipe 13. When the bleed pipe 13 is at normal pressure, the pneumatic normally-open external control valve 16 is bidirectionally open. When the bleed pipe 13 reaches a certain pressure, the pneumatic normally-open external control valve 16 is closed. The second one-way valve 17 is unidirectionally open, from the inside to the outside.

[0037] The deflation pipe 13 is provided with a deflation control valve, which includes a third one-way valve 18 . The third one-way valve 18 is unidirectional and conducts from outside to inside.

[0038] An exhaust control valve is installed on the exhaust pipe 14. The exhaust control valve includes a pneumatic normally closed external control valve 19 and a fourth one-way valve 20. The external control air path of the pneumatic normally closed external control valve 19 is connected to the bleed pipe 13. When the bleed pipe 13 is at normal pressure, the pneumatic normally closed external control valve 19 is closed. When the bleed pipe 13 reaches a certain pressure, the pneumatic normally closed external control valve 19 is bidirectional. The fourth one-way valve 20 is unidirectional, conducting air from the inside to the outside.

[0039] Among them, the first one-way valve 15, the pneumatic normally open external control valve 16, the second one-way valve 17, the third one-way valve 18, the pneumatic normally closed external control valve 19 and the fourth one-way valve 20 are all existing technologies, and their internal structures and working principles are not repeated here.

[0040] In this embodiment, the working process of the water-gas separation device is divided into two parts, namely the air intake process and the exhaust process.

[0041] Intake process: External air enters through the intake pipe 11, passes through the first one-way valve 15, and enters the upper chamber 7 along the tangent direction of the cavity. It then spirals downward along the inner tube. The inclined baffle 2 facilitates the formation of spiral motion. It then passes through the metal mesh pad 6 and enters the lower chamber 8. During this process, due to the large mass and inertia of water droplets, most of them will condense on the inner wall of the cavity, eventually accumulating and dripping to the bottom of the lower chamber 8. A small part of the water droplets are easily adsorbed by the metal mesh pad 6. When the water droplets grow large enough, they will also drip to the bottom of the lower chamber 8 due to the action of gravity.

[0042] Afterwards, it passes through the inner tube 9 into the left chamber 4, then passes through the filter 3 to absorb impurities and enter the right chamber 5, then enters the outlet pipe 12, and passes through the pneumatic normally open external control valve 16 and the second one-way valve 17 in sequence, and finally the dry and clean air is sent to the pneumatic system.

[0043] During the above-mentioned intake process, the exhaust pipe is at normal pressure, and the pneumatic normally open external control valve 16 is bidirectionally conductive. At this time, the outlet pipe 12 is unidirectionally conductive from inside to outside, the pneumatic normally closed external control valve 19 is closed, and the exhaust pipe 14 is in a cut-off state.

[0044] Exhaust process: Dry air from the pneumatic system enters through bleed pipe 13. When pressure builds up inside bleed pipe 13, pneumatic normally-open external control valve 16 closes, blocking outlet pipe 12. Normally-closed pneumatic external control valve 19 opens bidirectionally, while exhaust pipe 14 opens unidirectionally from inside to outside. The air then enters left chamber 4, passes through inner pipe 9 into lower chamber 8, and is finally discharged through exhaust pipe 14. This process also allows any liquid accumulated at the bottom of lower chamber 8 to be discharged.

[0045] Example 2: A preferred embodiment of the present invention provides a water-gas separation device for a submersible buoy pneumatic buoyancy adjustment system. The difference between this embodiment and the above-mentioned Example 1 is that the air inlet control valve, the air outlet control valve, the air release control valve and the exhaust control valve all use solenoid valves, and the other structures remain unchanged.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
