Description

Technical Field

[0001] The present application relates to the technical field of underwater vehicle drainage, and in particular to an air and carbon dioxide linked drainage device and an underwater vehicle. Background Art

[0002] With the maturity and development of underwater navigation technology, underwater vehicles need to drain water during the buoyancy process to achieve safe buoyancy. The biggest problem is that underwater vehicles generally use compressed air drainage or high-temperature gas drainage. Compressed air drainage uses the discharge of compressed air to discharge the water in the water storage tank, while high-temperature gas drainage uses the ignition of medicine to generate high-temperature gas, which enters the water tank and discharges the water. Compressed air drainage is greatly affected by water back pressure. As the working depth of the underwater vehicle gradually increases, the drainage capacity gradually decreases. The gas generated by high-temperature gas drainage is prone to secondary combustion, which is not conducive to safety. Using liquid carbon dioxide to gaseous state for drainage can use the ultra-high pressure during the carbon dioxide conversion process to reduce the pressure of the water in the water tank. However, in the related technology, carbon dioxide is easily cooled by water, which causes volume contraction and reduces the drainage capacity of the drainage device linked to air and carbon dioxide.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0028] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary and secondary relationship.

[0029] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0030] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the associated objects before and after are in an "or" relationship.

[0032] The term "multiple" as used in this application refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple sheets" refers to more than two sheets (including two sheets).

[0033] With the maturity and development of underwater navigation technology, underwater vehicles need to drain water during the process of surfacing. For example, when an underwater vehicle encounters unexpected situations such as rudder jam, water ingress, or depth loss, some stored seawater is quickly discharged in a short period of time to provide positive buoyancy, allowing the underwater vehicle to safely float.

[0034] The biggest problem is that underwater vehicles generally use compressed air or high-temperature gas to drain water. The compressed air drainage device is to compress and pressurize the air in advance and store it in a high-pressure air bottle. When needed, open the valve on the connecting pipe between the air bottle and the storage tank to introduce high-pressure air into the tank to discharge the internal seawater; the high-temperature gas drainage device is to seal the solid agent in the gas generator. When needed, the agent is ignited by an electrical signal to cause the agent to undergo a chemical reaction to form high-temperature gas, which is injected into the tank to discharge the internal seawater. As the working depth of the underwater vehicle gradually increases, the compressed air drainage is greatly affected by the back pressure, and the drainage capacity decreases significantly. The compressed air drainage is greatly affected by the water back pressure. As the working depth of the underwater vehicle gradually increases, the drainage capacity gradually decreases. The gas generated by the high-temperature gas drainage is easy to cause secondary combustion, which is not conducive to safety. If the water in the ballast water tank is directly discharged using a push plate or other device, due to the high pressure underwater, the push plate is under great pressure, which is easy to cause fatigue damage and fracture of the push plate. Using liquid carbon dioxide to gaseous state for drainage, the ultra-high pressure during the carbon dioxide conversion process can be used to reduce the pressure of the water in the water tank to discharge.

[0035] However, in the related art, carbon dioxide is easily cooled by water, which causes volume contraction and reduces the drainage capacity of the drainage device that combines air and carbon dioxide.

[0036] In view of this, in order to solve the technical problem that carbon dioxide is easily cooled by water, thereby causing volume contraction and reducing the drainage capacity of the air and carbon dioxide linkage drainage device. Some embodiments of the present application provide an air and carbon dioxide linkage drainage device and an underwater vehicle, and the air and carbon dioxide linkage drainage device includes a power unit, an air unit, a decompression unit, and a guide assembly.

[0037] The power unit has a first storage chamber, which is used to store liquid carbon dioxide. The air unit has a second storage chamber, which is used to store high-pressure air. The decompression unit has a decompression chamber, which can be selectively connected to the first storage chamber and the second storage chamber. The guide assembly has a first air inlet and a first air outlet, the first air inlet is connected to the decompression chamber, and the first air outlet is connected to the ballast water tank.

[0038] In the above scheme, the guide component has a first air inlet and a first air outlet, the first air inlet is connected to the decompression chamber, and the first air outlet is connected to the ballast water tank. Air can first enter the guide component from the first air inlet, and then enter the ballast water tank to form an air cushion in the ballast water tank. After carbon dioxide enters the ballast water tank, there is an air cushion between the carbon dioxide and water. The air cushion can reduce the direct contact time between carbon dioxide and water, reduce the energy loss of carbon dioxide, and further reduce the degree of volume contraction of carbon dioxide when it is cooled by water, so that it maintains a larger volume, thereby improving the drainage capacity of the drainage device in which air and carbon dioxide are linked.

[0039] The underwater vehicle disclosed in the embodiment of the present application can be used in high-pressure environments such as the deep sea, and can also be used in non-high-pressure environments such as rivers and lakes.

[0040] For the convenience of description, the following embodiments are described by taking the air and carbon dioxide linked drainage device of one embodiment of the present application as an example.

[0042] Please refer to Figures 1 to 4 In this embodiment, the drainage device 100 linked with air and carbon dioxide includes a power unit 110, an air unit 120, a decompression unit 130 and a guide assembly 140. The power unit 110 has a first storage chamber 111, and the first storage chamber 111 is used to store liquid carbon dioxide. The air unit 120 has a second storage chamber 121, and the second storage chamber 121 is used to store high-pressure air. The decompression unit 130 has a decompression chamber 131, and the decompression chamber 131 can be selectively connected to the first storage chamber 111 and the second storage chamber 121. The guide assembly 140 has a first air inlet 141 and a first air outlet 142, and the first air inlet 141 is connected to the decompression chamber 131, and the first air outlet 142 is connected to the ballast water tank 220.

[0043] The drainage device 100 linked with air and carbon dioxide comprises a power unit 110. Under the compression of the power unit 110, carbon dioxide is in a liquid state in a first storage chamber 111, and the carbon dioxide is stored in the first storage chamber 111. The air unit 120 comprises a second storage chamber 121, and the second storage chamber 121 is used to store high-pressure air. The air can be in a gaseous state in the second storage chamber 121. The decompression unit 130 has a decompression chamber 131. Exemplarily, the decompression chamber 131 can be constructed as a hollow thin-walled cylinder. The decompression chamber 131 can be selectively connected with the first storage chamber 111 and the second storage chamber 121. The carbon dioxide in the first storage chamber 111 can enter the decompression chamber 131. When the carbon dioxide enters the decompression chamber 131, the pressure of the carbon dioxide is reduced. The high-pressure air stored in the second storage chamber 121 can also enter the decompression chamber 131. After the air enters the decompression chamber 131, the pressure is also reduced. The guide component 140 has a first air inlet 141 and a first air outlet 142. After air or carbon dioxide enters the decompression chamber 131, it then enters the first air inlet 141 of the guide component 140 from the decompression chamber 131, then exits the guide component 140 from the first air outlet 142, and then enters the ballast water tank 220. Water is stored in the ballast water tank 220. After air or carbon dioxide enters the ballast water tank 220, the water in the ballast water tank 220 will be discharged.

[0044] Since the temperature of gaseous carbon dioxide decreases when it meets water, the gas shrinks, so the drainage capacity of carbon dioxide gas will be weakened. Therefore, the high-pressure air stored in the second storage chamber 121 can be discharged first to form an air cushion, and then the carbon dioxide can be discharged to avoid direct contact between carbon dioxide and water. Exemplarily, the high-pressure air in the second storage chamber 121 in the air unit 120 is first discharged to enter the decompression chamber 131, and then enters the guide assembly 140 from the decompression chamber 131, and enters the ballast water tank 220 after flowing through the guide assembly 140, so that part of the water in the ballast water tank 220 can be discharged, and then an air cushion is formed in the ballast water tank 220, and then the carbon dioxide in the second storage chamber 121 is released, so that the carbon dioxide in the second storage chamber 121 enters the ballast water tank 220, thereby enabling the water in the ballast water tank 220 to be discharged. Carbon dioxide is liquid under a certain pressure and temperature, has a high density, and is easy to store. When the temperature and pressure of carbon dioxide are increased, it can be quickly converted into a supercritical state, with its volume expanding several times. It has strong instantaneous working ability and can discharge water under high water pressure conditions, making it suitable for operations in high-pressure environments such as the deep sea.

[0045] Moreover, the drainage device 100 linked with air and carbon dioxide combines liquid carbon dioxide and high-pressure air as power sources. Liquid carbon dioxide can quickly produce a large amount of gas when it is gasified, providing a strong driving force. For a large underwater vehicle 230, once the underwater vehicle 230 is located deep on the seabed, the water pressure on the ballast tank 220 is relatively large. Without the strong driving force of carbon dioxide, it is difficult to discharge the water in the ballast tank 220. High-pressure air can also be used as an auxiliary power to ensure the continuity and stability of drainage. The gas after the liquid carbon dioxide is gasified is usually harmless carbon dioxide gas, which will not pollute the environment when discharged into the atmosphere. At the same time, the design of the device also reduces the direct discharge of wastewater, which helps to protect water resources and the ecological environment. In addition, due to the modular design and high-quality material manufacturing, the device has high reliability and durability, can operate stably for a long time and meet various drainage needs.

[0046] Specifically, the guide component 140 has a first air inlet 141 and a first air outlet 142. The first air inlet 141 is connected to the decompression chamber 131, and the first air outlet 142 is connected to the ballast water tank 220. Air can first enter the guide component 140 from the first air inlet 141, and then enter the ballast water tank 220 to form an air cushion with the ballast water tank 220. After carbon dioxide enters the ballast water tank 220, there is an air cushion between the carbon dioxide and the water. The air cushion can reduce the direct contact time between carbon dioxide and water or avoid contact between carbon dioxide and water, thereby reducing the energy loss of carbon dioxide, and thereby reducing the degree of volume contraction of carbon dioxide when it is cooled by water, so that it maintains a larger volume, thereby improving the drainage capacity of the drainage device 100 in which air and carbon dioxide are linked.

[0047] Please refer to Figures 1 to 5 In this embodiment, the air unit 120 has a first outlet 122, which is connected to the second storage chamber 121 and the decompression chamber 131. The air unit 120 also includes a first valve 123, which is arranged at the first outlet 122. The first valve 123 can selectively open and close the first outlet 122.

[0048] The air unit 120 has a first outlet 122, and the first outlet 122 and the second storage chamber 121 are connected to the decompression chamber 131. That is to say, the air stored in the second storage chamber 121 can leave the air unit 120 from the first outlet 122 and then enter the decompression chamber 131. The air unit 120 also includes a first valve 123, which is arranged at the first outlet 122. The first valve 123 can selectively open or close the first outlet 122. For example, when the first valve 123 is opened, the air stored in the second storage chamber 121 can leave the second storage chamber 121 from the first outlet 122 and enter the decompression chamber 131. When the first valve 123 is closed, the air stays inside the second storage chamber 121, and the air will not leave the second storage chamber 121.

[0049] Specifically, the air unit 120 also includes a first valve 123, which is arranged at the first outlet 122. The first valve 123 can selectively open and close the first outlet 122, and can accurately control the air flow of the first outlet 122, thereby controlling the drainage volume, thereby improving the stability and reliability of the operation of the drainage device 100 linked with air and carbon dioxide.

[0050] In some embodiments, the first valve 123 can be designed as a solenoid valve. The response time of the solenoid valve is usually very short, which can be as short as several milliseconds. Even a pilot solenoid valve can be controlled within tens of milliseconds. This fast response capability enables the solenoid valve to quickly adjust the opening and closing state of the valve according to the control signal, thereby realizing the precise control of the internal pressure and flow of the drainage device 100 linked with air and carbon dioxide. By precisely controlling the position of the valve core through electromagnetic force, the solenoid valve can realize the precise regulation of the water flow, which is very important for the drainage system that requires high-precision control, and can ensure the stability and efficiency of the system. During the buoyancy of the underwater vehicle 230, the pressure on the underwater vehicle 230 gradually decreases, while the buoyancy on the underwater vehicle 230 is constant. Therefore, when the underwater vehicle 230 just starts to drain, the valve opening angle of the solenoid valve can be adjusted to be larger so that more water can be discharged. During the ascent of the underwater vehicle 230, the valve opening angle of the solenoid valve can be gradually reduced, thereby gradually reducing the drainage volume, so that it meets the uniform speed or uniform acceleration ascent, and improving the operation stability and reliability of the underwater vehicle 230.

[0051] Please refer to Figure 5In the present embodiment, the air unit 120 includes a first peripheral wall 124, a first bottom wall 125 and a second bottom wall 126. Along the first direction X, the two ends of the first peripheral wall 124 are respectively connected to the outer peripheral edge of the first bottom wall 125 and the outer peripheral edge of the second bottom wall 126. The first bottom wall 125 is provided with a first outlet 122. The air unit 120 also includes a first plate portion 150. Along the first direction X, the outer peripheral surface of the first plate portion 150 is slidably connected to the inner peripheral surface of the first peripheral wall 124.

[0052] The air unit 120 includes a first peripheral wall 124, a first bottom wall 125 and a second bottom wall 126. Along the first direction X, the first bottom wall 125 and the second bottom wall 126 are arranged opposite to each other. The two ends of the first peripheral wall 124 are respectively connected to the outer peripheral edge of the first bottom wall 125 and the outer peripheral edge of the second bottom wall 126. The first outlet 122 is arranged on the first bottom wall 125. That is, the first bottom wall 125 is closer to the decompression chamber 131, and the second bottom wall 126 is farther from the decompression chamber 131. Since the air pressure inside the air unit 120 is too low to completely discharge the water from the ballast water tank 220 during the process of releasing air from the air unit 120, a first plate portion 150 may be provided inside the air unit 120, and the outer peripheral surface of the first plate portion 150 is slidably connected to the inner peripheral surface of the first peripheral wall 124, that is, along the first direction X, the first plate portion 150 and the first peripheral wall 124 may be relatively displaced, and the first plate portion 150 may push the remaining air in the air bottle toward the ballast water tank 220, thereby improving the utilization efficiency of the air in the air unit 120 and solving the problem that the air cannot discharge the water from the ballast water tank 220 when the underwater vehicle 230 is located at a deeper position.

[0053] Specifically, the air unit 120 also includes a first plate portion 150. Along the first direction X, the outer peripheral surface of the first plate portion 150 is slidably connected to the inner peripheral surface of the first peripheral wall 124, which can improve the utilization efficiency of the air in the air bottle, enable the ballast water tank 220 to discharge more water, and form a thicker air cushion, further reducing the probability of cooling of carbon dioxide when in contact with water, thereby improving the operating efficiency and reliability of the drainage device 100 in which air and carbon dioxide are linked.

[0054] Please refer to Figure 5 In this embodiment, the air unit 120 further includes a first driving member 160 , which is disposed on the second bottom wall 126 , and a power output end of the first driving member 160 is connected to the first plate portion 150 .

[0055] The air unit 120 includes a first driving member 160, which can be constructed as a driving motor. The first driving member 160 is arranged on the second bottom wall 126. The first driving member 160 has a power output end. The power output end of the first driving member 160 is connected to the first plate portion 150. The first driving member 160 can control the first plate portion 150 to move in the first direction X.

[0056] Exemplarily, the first plate portion 150 can be attached to the inner wall of the air unit 120, and the first driving member 160 is arranged on the second bottom wall 126, that is, at a position away from the first outlet 122 of the air unit 120. The air of the air unit 120 is discharged into the ballast water tank 220. Since the air in the air unit 120 needs to meet a certain pressure to discharge the water in the ballast water tank 220, there will inevitably be residual air in the air unit 120 that cannot be discharged. In this way, the first driving member 160 can be used to drive the first plate portion 150 to move along the first direction X and toward the first outlet 122, so as to squeeze the remaining air in the air unit 120, and squeeze the remaining air into the ballast water tank 220, thereby improving the utilization efficiency of the air unit 120.

[0057] Specifically, the power output end of the first driving member 160 is connected to the first plate portion 150. The introduction of the first driving member 160 provides an additional power source for the air unit 120. By precisely controlling the operating speed and strength of the first driving member 160 and thereby controlling the movement of the first plate portion 150, fine adjustment of parameters such as the air flow and pressure inside the air unit 120 can be achieved, thereby improving the operating efficiency of the drainage device 100 that links air and carbon dioxide.

[0058] Please refer to Figure 5 In this embodiment, the air unit 120 further includes a first sealing member 170 , which is disposed between the first plate portion 150 and the inner circumferential surface of the first circumferential wall 124 .

[0059] The first seal 170 is arranged between the first plate portion 150 and the inner circumferential surface of the first circumferential wall 124. The first seal 170 can play a sealing role. When the first plate portion 150 moves along the first direction X, the first seal 170 can prevent the air between the first plate portion 150 and the first bottom wall 125 from entering between the first plate portion 150 and the second bottom wall 126. This can increase the pressure of the air in the air unit 120, and press the air in the air unit 120 into the ballast water tank 220, thereby forming a thicker air cushion, discharging more water from the ballast water tank 220, further reducing the volume shrinkage caused by the cooling of carbon dioxide, and improving the drainage capacity of the drainage device 100 in which air and carbon dioxide are linked. It can be understood that the material of the first sealing member 170 can be natural rubber, nitrile rubber (NBR), ethylene propylene diene monomer rubber (EPDM), silicone rubber and fluororubber. Natural rubber has good elasticity and sealing properties, and is suitable for sealing general media such as water and air. Nitrile rubber (NBR) has good oil resistance and is suitable for sealing occasions in contact with oil media. Ethylene propylene diene monomer rubber (EPDM) has excellent ozone resistance and chemical corrosion resistance and is suitable for outdoor or chemically corrosive media environments. Silicone rubber has good high and low temperature stability and can maintain sealing performance under extreme temperature conditions. Fluororubber has excellent corrosion resistance, high temperature resistance and oil resistance, and is suitable for sealing highly corrosive, high temperature or oily media.

[0060] Specifically, the first seal 170 is disposed between the first plate portion 150 and the inner circumferential surface of the first circumferential wall 124, which enables the air to form a thicker air cushion in the ballast water tank 220, further reducing the probability of carbon dioxide being cooled when encountering water, and improving the drainage efficiency of the drainage device 100 in which air and carbon dioxide are linked.

[0061] Please refer to Figures 1 to 6 In this embodiment, the first plate portion 150 also includes a first groove 151, which is arranged on the outer peripheral surface of the first plate portion 150, the first groove 151 is constructed in an annular shape and extends along the circumference of the first plate portion 150, and the first sealing member 170 is arranged in the first groove 151.

[0062] The first plate portion 150 further includes a first groove 151, the opening of the first groove 151 faces the first peripheral wall 124, and the first groove 151 is arranged on the outer peripheral surface of the first plate portion 150. The shape of the first groove 151 is annular and extends along the circumference of the first plate portion 150. It can be understood that the opening of the first groove 151 is substantially perpendicular to the first direction X. The first seal 170 can be arranged between the first groove 151 and the first peripheral wall 124. The first groove 151 provides a stable installation position for the first seal 170, ensuring that the first seal 170 can be closely fitted between the first plate portion 150 and the first peripheral wall 124, and effectively preventing the air between the first plate portion 150 and the first bottom wall 125 from entering between the first plate portion 150 and the second bottom wall 126. Moreover, the first seal 170 is installed in the first groove 151, which can increase the contact area between the first seal 170 and the first plate portion 150 and the first peripheral wall 124, thereby improving the reliability and stability of the seal. In addition, the design of the first groove 151 makes the installation of the first seal 170 more convenient and quick, without the need for additional fixing devices or adhesives, thereby reducing the difficulty and cost of installation. The existence of the first groove 151 can enhance the structural strength of the first plate portion 150 to a certain extent, making it more able to withstand external pressure or impact, and improving the overall stability of the air and carbon dioxide linkage drainage device 100.

[0063] Specifically, the first groove 151 is constructed in an annular shape and extends along the circumference of the first plate portion 150. The first seal 170 is arranged in the first groove 151, which can provide a stable installation position for the first seal 170, ensuring that the first seal 170 can fit tightly between the first plate portion 150 and the first peripheral wall 124, and effectively prevent the air between the first plate portion 150 and the first bottom wall 125 from entering between the first plate portion 150 and the second bottom wall 126, so that a thicker air cushion is formed in the ballast water tank 220, further reducing the probability of carbon dioxide being cooled by water, and improving the stability and reliability of the drainage device 100 in which air and carbon dioxide are linked.

[0064] Please refer to Figures 1 to 9 In this embodiment, the air unit 120 further includes a pressure detection unit and a control unit. The control unit is connected to the pressure detection unit and the first driving member 160 respectively. The pressure detection unit is disposed at the first outlet 122 .

[0065] The air unit 120 may further include a pressure detection unit and a control unit. The pressure detection unit is used to detect the pressure of the air in the second storage chamber 121. The control unit is connected to the pressure detection unit and the first driving member 160 respectively. The pressure detection unit sends the detected air pressure value to the control unit. The control unit controls the first driving member 160 according to the data detected by the pressure detection unit, and controls the first plate portion 150 to move along the first direction X and toward the first bottom wall 125. For example, when the air pressure value is lower than the first threshold value, the control unit controls the first driving member 160 to move the first plate portion 150. When the air pressure value is higher than the first threshold value, the control unit does not control the first driving member 160. The pressure detection unit may be arranged at the first outlet 122. Since the air is discharged from the second storage chamber 121 through the first outlet 122, the pressure detection unit is arranged at the first outlet 122, so that the air pressure value can be measured more truly and accurately.

[0066] Specifically, the control unit is respectively connected to the pressure detection unit and the first driving member 160. The pressure detection unit is arranged at the first outlet 122, so that the drainage device 100 linked with air and carbon dioxide can adjust the position of the first plate portion 150 according to the air pressure value at the first outlet 122, thereby changing the pressure value of the air in the second storage chamber 121, so that more water in the ballast water tank 220 is discharged, and a thicker air cushion is formed in the ballast water tank 220, thereby further reducing the probability of carbon dioxide being cooled by water and improving the drainage efficiency of the drainage device 100 linked with air and carbon dioxide.

[0067] Please refer to Figures 9 to 11 In some embodiments, when the underwater vehicle 230 needs to quickly float and the air and carbon dioxide linked drainage device 100 needs to quickly drain water, the control unit receives the rapid floating signal of the underwater vehicle 230. The control unit can control the first driving member 160 to accelerate the position of the first plate portion 150 according to the floating demand of the underwater vehicle 230, so that more air can enter the ballast water tank 220 in a shorter time, so that the underwater vehicle 230 can discharge more water, thereby enabling the underwater vehicle 230 to quickly float.

[0068] Please refer to Figures 9 to 11In some embodiments, a guide assembly 140 is provided between the drainage device 100 linked to air and carbon dioxide and the ballast water tank 220, one end of the guide assembly 140 is communicated with the drainage device 100 linked to air and carbon dioxide, and the other end of the guide assembly 140 is communicated with the ballast water tank 220, and air or carbon dioxide can enter the ballast water tank 220 from the drainage device 100 linked to air and carbon dioxide through the guide assembly 140, and a first exhaust valve 260 can be provided on the guide assembly 140, and the first exhaust valve 260 is used to control the exhaust volume of the drainage device 100 linked to air and carbon dioxide per unit time, that is, the flow rate and flow velocity of the gas. For example, the first exhaust valve 260 can control the speed of the underwater vehicle 230 to precisely control the buoyancy when it is navigating underwater, An exhaust valve 260 is connected to the control unit, and the control unit can control the opening and closing degree of the first exhaust valve 260 on the guide component 140, thereby controlling the flow rate and flow velocity of the gas through the guide component 140. For example, when the underwater vehicle 230 needs to float quickly, for example, the floating speed is 10m / s, the first exhaust valve 260 can be fully opened to allow the gas (carbon dioxide or air) to pass through the guide component 140 at a maximum flow rate and flow velocity and enter the ballast water tank 220 to discharge the water in the ballast water tank 220. When the underwater vehicle 230 needs to float at a moderate speed, for example, the floating speed is 5m / s, the first exhaust valve 260 can be in a semi-open state to allow the gas to flow out at a corresponding flow rate and flow velocity per unit time, thereby accurately controlling the floating of the underwater vehicle 230.

[0069] Please refer to Figures 9 to 11 In some embodiments, the underwater vehicle 230 further includes a gas recovery device 270, which can be selectively connected to the ballast water tank 220. When the underwater vehicle 230 floats up, the gas recovery device 270 is not connected to the ballast water tank 220. When the underwater vehicle 230 needs to sink, the gas recovery device 270 is connected to the ballast water tank 220, and the air and carbon dioxide in the ballast water tank 220 flow into the gas recovery device 270. The ballast water tank 220 is refilled with water, thereby increasing the weight of the underwater vehicle 230, making the weight of the underwater vehicle 230 greater than the buoyancy, and thereby allowing the underwater vehicle 230 to sink.

[0070] Please refer to Figures 9 to 11In some embodiments, the gas recovery device 270 includes a second peripheral wall 271, a third bottom wall 272 and a fourth bottom wall 273. The two ends of the second peripheral wall 271 are respectively connected to the outer peripheral edges of the third bottom wall 272 and the outer peripheral edges of the fourth bottom wall 273. The third bottom wall 272 is provided with a third outlet 274, and the third outlet 274 is communicated with the ballast water tank 220. The air or carbon dioxide in the ballast water tank 220 enters the gas recovery device 270 through the third outlet 274. The gas recovery device 270 also includes a second plate portion 275, the outer circumference of the second plate portion 275 is slidably connected to the inner circumference of the second peripheral wall 271, and the second plate portion 275 is movably arranged on the inner circumference of the second peripheral wall 271. When the gas enters the gas recovery device 270, the second plate portion 275 is controlled to be away from the third outlet 274, so that the gas enters the gas recovery device 270. When the underwater vehicle 230 needs to float, the second plate portion 275 is controlled to be close to the third outlet 274, and the carbon dioxide and air in the gas recovery device 270 are discharged into the ballast water tank 220.

[0071] Please refer to Figures 9 to 11 In some embodiments, the ballast water tank 220 discharges water through the outlet of the first pipe 240. A Helmholtz resonator is arranged along the circumference of the outlet of the first pipe 240. Each Helmholtz resonator unit is processed from a 316L stainless steel substrate, and includes a cylindrical cavity and a slit neck. For example, the cavity diameter can be 2.0 mm, the cavity height can be 5.0 mm, the neck width can be 0.3 mm, and the neck length can be 0.5 mm. When the sound wave frequency matches the resonant frequency of the Helmholtz resonator, the sound wave generates high-speed oscillations in the neck, and converts sound energy into heat energy through viscous dissipation and heat conduction effects. The neck of the Helmholtz resonator can be embedded with a piezoelectric ceramic sheet. A MEMS hydrophone array can be arranged at the outlet of the first pipe 240. The MEMS hydrophone is used to collect noise signals in real time, and outputs analog voltages to corresponding piezoelectric ceramic sheets through a conversion module. The adjustment time can be less than 5 seconds. The Helmholtz resonator is running to reduce or eliminate the drainage noise at the outlet of the first pipe 240.

[0072] Please refer to Figures 9 to 11 In some embodiments, underwater vehicle 230 may be a submarine.

[0073] Please refer to Figures 9 to 11In some embodiments, the power unit 110 includes a third peripheral wall 280, a fifth bottom wall 281, and a sixth bottom wall 282. The power unit 110 also includes a second driving member 283, which is disposed on the fifth bottom wall 281. The power output end of the second driving member 283 is connected to the third plate portion 284. The power unit 110 also includes a second sealing member 285, which is disposed between the third plate portion 284 and the inner peripheral surface of the third peripheral wall 280. The third plate portion 284 also includes a second groove 286, which is disposed on the third plate portion 284. The outer peripheral surface of the third plate portion 284 has a second groove 286 that is annular and extends circumferentially. The second sealing member 285 is disposed in the second groove 286. The sixth bottom wall 282 is provided with a second outlet 113 that is connected to the decompression chamber 131. The second driving member 283 can drive the third plate portion 284 to move toward the second outlet 113, thereby squeezing the carbon dioxide stored in the power unit 110 into the decompression chamber 131, thereby discharging more water, thereby improving the utilization rate of the carbon dioxide and improving the drainage efficiency of the drainage device 100 in which air and carbon dioxide are linked.

[0074] In some embodiments, the air and carbon dioxide linkage drainage device 100 further includes a bionic gill-type multilayer gas exchange membrane, which includes a base layer, a functional layer, and a protective layer. The base layer is constructed of polytetrafluoroethylene (PTFE) and a porous membrane (pore size 0.2 microns) to provide mechanical support, the functional layer is constructed of a lipid bilayer structure imitating fish gill cells, and a recombinant aquaporin (Aquaporin-Z) is embedded to selectively block the permeation of carbon dioxide molecules, and the protective layer is constructed of a silicon dioxide nanocoating (thickness 50nm) to prevent biological fouling from attaching. The multilayer gas exchange membrane is movably arranged inside the ballast water tank 220 and between the water and the air cushion, further reducing the probability of carbon dioxide contacting water, reducing the probability of carbon dioxide cooling and shrinking, allowing more water to be discharged from the air and carbon dioxide linkage drainage device 100, and further improving the drainage efficiency of the air and carbon dioxide linkage drainage device 100.

[0075] Please refer to Figures 1 to 9 In this embodiment, the air and carbon dioxide linked drainage device 100 includes a plurality of power unit groups and a plurality of decompression units 130, the plurality of power unit groups correspond one to one with the plurality of decompression units 130, each power unit group includes a plurality of power units 110, and the first storage chamber 111 of each power unit group can be selectively connected to the decompression chamber 131 of the corresponding decompression unit 130.

[0076] The drainage device 100 linked with air and carbon dioxide includes a plurality of power unit groups, so that the drainage device 100 linked with air and carbon dioxide can flexibly adjust the power output according to the drainage demand. When a large amount of drainage is required for the ballast water tank 220, more power unit groups can be started to improve the drainage efficiency. The plurality of power unit groups correspond to the plurality of decompression units 130 one by one, that is, the carbon dioxide of the plurality of power unit groups can exit the power unit group and then enter the decompression chamber 131. Each power unit group includes a plurality of power units 110. When the carbon dioxide needs to be discharged from the first storage chamber 111, the first storage chamber 111 of each power unit 110 can be connected to the decompression chamber 131, and then the carbon dioxide exits the first storage chamber 111 and enters the decompression chamber 131. For example, a first bursting disk can be arranged between the decompression chamber 131 and the first storage chamber 111. When the pressure value of the carbon dioxide exceeds a certain threshold, the carbon dioxide will break through the first bursting disk and enter the decompression chamber 131 from the first storage chamber 111.

[0077] Specifically, the first storage chamber 111 of each power unit group can be selectively connected to the decompression chamber 131 of the corresponding decompression unit 130. When the underwater vehicle 230 needs to float, carbon dioxide can enter the ballast water tank 220 and then discharge the water, thereby improving the drainage efficiency of the drainage device 100 that links air and carbon dioxide.

[0078] Please refer to Figures 1 to 12 In some embodiments, the air and carbon dioxide linked drainage device 100 further includes a first buffer plate 290, which can be arranged on the inner wall of the decompression chamber 131, and a plurality of first holes 300 are arranged on the first buffer plate 290, and along the thickness direction of the first buffer plate 290, the plurality of first holes 300 penetrate the first buffer plate 290, and the first hole 300 includes a first end 301 and a second end 302, and along the thickness direction of the first buffer plate 290, the first end 301 and the second end 302 are arranged oppositely, and the radial dimension of the first end 301 is greater than the radial dimension of the second end 302, and the diameter of the first hole 300 from the first end 301 to the second end 302 is greater than the radial dimension of the first hole 300. The size gradually increases, and the air or carbon dioxide enters the first hole 300 from the second end 302, and then flows to the flow guide component 140 from the first end 301. At the moment of release, the air or carbon dioxide has a larger pressure, a larger impact force, and a smaller volume. By setting the first buffer plate 290, the air or carbon dioxide can be buffered, and the impact of the air or carbon dioxide entering the ballast water tank 220 is reduced, so that the air and carbon dioxide can be more fully released in the second pressure reducing pipeline 132, and the volume of the air or carbon dioxide is expanded, so that more air or carbon dioxide can enter the ballast water tank 220, thereby improving the drainage capacity of the drainage device 100 in which air and carbon dioxide are linked.

[0079] Please refer to Figures 1 to 9 In this embodiment, the air and carbon dioxide linked drainage device 100 also includes an excitation member 112, which is disposed in the first storage chamber 111. The excitation member 112 is configured to receive a control signal and generate heat so that the liquid carbon dioxide absorbs heat and is converted into high-pressure supercritical carbon dioxide.

[0080] The drainage device 100 linked to air and carbon dioxide may further include an excitation member 112, which is disposed in the first storage chamber 111. The excitation member 112 may receive a control signal and then generate heat, so that the liquid carbon dioxide absorbs the heat and is converted into high-pressure supercritical carbon dioxide. The supercritical carbon dioxide may be used as a power source to provide additional energy support for the drainage device 100 linked to air and carbon dioxide, thereby allowing the high-pressure carbon dioxide to enter the ballast water tank 220 and discharge the water in the ballast water tank 220.

[0081] Specifically, the excitation element 112 is constructed to receive a control signal and generate heat so that the liquid carbon dioxide absorbs heat and is converted into high-pressure supercritical carbon dioxide. The high-pressure supercritical carbon dioxide can be utilized. On the one hand, since the pressure of the liquid carbon dioxide increases in the process of becoming a supercritical state, this can reduce dependence on external energy, discharge water from the ballast water tank 220, and improve the operating efficiency of the drainage device 100 that links air and carbon dioxide.

[0082] In some embodiments, the power unit 110 is provided with a second outlet 113 , and the decompression unit 130 is provided with a communication port 210 . The second outlet 113 and the communication port 210 are in communication, so that the carbon dioxide of the power unit 110 enters the chamber.

[0083] In some embodiments, a plurality of decompression units 130 are provided with connecting ports 210, and a connecting pipe 200 may be provided on the connecting port 210, and the connecting pipe 200 is connected to the connecting port 210, and the decompression chambers 131 of the plurality of decompression units 130 are connected through the plurality of connecting pipes 200. Exemplarily, the decompression chamber 131 may have two connecting ports 210, one connecting port 210 is used to connect with the power unit 110, and the other connecting port 210 is used to connect with another decompression chamber 131.

[0084] In some embodiments, the decompression unit 130 and the air unit 120 may be connected via a connecting pipe 200 .

[0085] In some embodiments, the air and carbon dioxide linked drainage device 100 is provided with a mounting seat 190 , and the power unit 110 , the decompression unit 130 , and the air unit 120 can all be arranged on the mounting seat 190 .

[0086] The embodiment of the present application further provides an underwater vehicle 230, comprising the air and carbon dioxide linked drainage device 100 in any one of the embodiments of the present application.

[0087] The underwater vehicle 230 proposed in the embodiment of the present application, the guide component 140 has a first air inlet 141 and a first air outlet 142, the first air inlet 141 is connected to the decompression chamber 131, and the first air outlet 142 is connected to the ballast water tank 220. Air can first enter the guide component 140 from the first air inlet 141, and then enter the ballast water tank 220, forming an air cushion in the ballast water tank 220. After carbon dioxide enters the ballast water tank 220, there is an air cushion between the carbon dioxide and water. The air cushion can reduce the direct contact between carbon dioxide and water, reducing the probability of carbon dioxide temperature reduction, and further reducing the probability of carbon dioxide shrinking in volume when cooled by water, thereby improving the drainage capacity of the drainage device 100 in which air and carbon dioxide are linked.

[0088] In some embodiments, air or carbon dioxide can enter the ballast water tank 220 from the air and carbon dioxide coupled drainage device 100 , and then the water in the ballast water tank 220 is discharged from the underwater vehicle 230 through the first pipe 240 , thereby reducing the weight of the underwater vehicle 230 .

[0089] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
