Description

Technical Field

[0001] This application relates to the field of underwater vehicle drainage technology, and more particularly to a drainage device and an underwater vehicle that links air and carbon dioxide. Background Technology

[0002] With the maturity and development of underwater navigation technology, underwater vehicles need to dewater during the ascent process to achieve safe surfacing. Larger underwater vehicles generally use compressed air dewatering or high-temperature gas dewatering. Compressed air dewatering uses the discharge of compressed air to expel water from the water tank, while high-temperature gas dewatering uses the ignition of a propellant to generate high-temperature gas, which enters the water tank and expels the water. Compressed air dewatering is greatly affected by water back pressure, and its dewatering capacity gradually decreases as the operating depth of underwater vehicles gradually increases. High-temperature gas dewatering is prone to secondary combustion, which is detrimental to safety.

[0003] Compressed air and water in the ballast tank form an air cushion, and then liquid carbon dioxide is converted into a supercritical state for drainage. The extremely high pressure generated during the carbon dioxide conversion process expels the water from the ballast tank, thus avoiding direct contact between carbon dioxide and water for cooling. However, in related technologies, the air temperature decreases during release and upon contact with water, causing the air volume to shrink and reducing the drainage capacity of the air-carbon dioxide linked drainage device. Summary of the Invention

[0004] This application provides a drainage device and an underwater vehicle that link air and carbon dioxide, which solves the technical problem that the temperature of air decreases when it comes into direct contact with water, causing the air volume to shrink and reducing the drainage capacity of the drainage device that links air and carbon dioxide.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In a first aspect, embodiments of this application propose an air-carbon dioxide linkage drainage device. The air-carbon dioxide linkage drainage device includes a power unit, an air unit, a pressure reducing unit, and a flow guiding component. The power unit has a first storage chamber for storing liquid carbon dioxide. The air unit has a second storage chamber for storing high-pressure air. The pressure reducing unit has a pressure reducing chamber, which can be selectively connected to both the first and second storage chambers. The flow guiding component has a first air inlet and a first air outlet. The first air inlet is connected to the pressure reducing chamber, and the first air outlet is connected to the ballast water tank. A first heating source is provided in the second storage chamber. The first heating source is adapted to generate heat after receiving a signal to heat the air stored in the second storage chamber.

[0007] The second storage chamber is equipped with a first heating source. The first heating source is adapted to generate heat after receiving a signal to heat the air stored in the second storage chamber. In this way, when the air and carbon dioxide linked drainage device is running, on the one hand, the first heating source can raise the air temperature in the second storage chamber and expand the air volume, thereby enabling more water to be discharged from the ballast water tank. On the other hand, the first heating source can also maintain the air temperature at the raised temperature and reduce the degree of air volume contraction when it encounters water cooling, thereby improving the drainage efficiency of the air and carbon dioxide linked drainage device.

[0008] Optionally, the first heating source is configured as an excitation agent assembly, which includes an agent body and an excitation unit. The excitation unit is adapted to excite the agent body after receiving a signal, so that the agent body undergoes a chemical reaction and generates heat.

[0009] The excitation unit is adapted to excite the drug body after receiving a signal, so that the drug body undergoes a chemical reaction and generates heat. This can improve the drainage efficiency of the air-carbon dioxide linked drainage device and reduce the probability of the air-carbon dioxide linked drainage device malfunctioning.

[0010] Optionally, the first heating source is configured as a PTC heating element.

[0011] The heating source is a PTC heating element, which can heat efficiently and control the temperature precisely. This automatic temperature control function helps to maintain stable heating of the air in the drainage device that links air and carbon dioxide, thereby improving drainage efficiency.

[0012] Optionally, the air and carbon dioxide linked drainage device also includes an insulation layer that covers the inner wall of the second storage chamber to keep the air inside the second storage chamber warm.

[0013] An insulation layer is installed inside the second storage chamber, and the insulation layer is located on the inner wall of the second storage chamber. This can keep the air inside the second storage chamber warm, reduce the chance of air cooling, and improve the operating efficiency and performance of the air and carbon dioxide linkage drainage device.

[0014] Optionally, the air unit has a first outlet connected to a second storage chamber and a depressurization chamber. The air unit also includes a rupture diaphragm disposed at the first outlet, the rupture diaphragm being configured to tear when the pressure in the second storage chamber reaches a first preset value.

[0015] As a pressure-sensitive element, the rupture diaphragm can automatically tear when the pressure in the second storage chamber reaches a preset safety limit, thereby releasing excessive pressure. This design effectively prevents equipment damage or safety accidents caused by excessive pressure, and optimizes the working pressure range of the air and carbon dioxide linked drainage device, thereby improving drainage efficiency. When the pressure reaches the first preset value, the rupture diaphragm automatically tears, allowing high-pressure air to smoothly enter the decompression chamber and drive the drainage process.

[0016] Optionally, the air unit includes a first peripheral wall, a first bottom wall, and a second bottom wall. Along a first direction, the two ends of the first peripheral wall are respectively connected to the outer peripheral edges of the first bottom wall and the second bottom wall. The first bottom wall is provided with a first outlet. The air unit also includes a first plate portion. Along the first direction, the outer peripheral surface of the first plate portion is slidably connected to the inner peripheral surface of the first peripheral wall.

[0017] The air unit also includes a first plate, and along the first direction, the outer peripheral surface of the first plate is slidably connected to the inner peripheral surface of the first peripheral wall. This can improve the utilization efficiency of air in the air bottle, allow more water to be discharged from the ballast water tank, form a thicker air cushion, further reduce the probability of carbon dioxide cooling upon contact with water, and improve the operating efficiency and reliability of the air and carbon dioxide linked drainage device.

[0018] Optionally, the air unit further includes a first drive member disposed on the second bottom wall, and the power output end of the first drive member is connected to the first plate.

[0019] The power output end of the first drive component is connected to the first plate. The introduction of the first drive component provides an additional power source for the air unit. By precisely controlling the operating speed and force of the first drive component, and thus controlling the movement of the first plate, it is possible to achieve fine adjustment of parameters such as airflow and pressure inside the air unit, thereby improving the operating efficiency of the air and carbon dioxide linkage drainage device.

[0020] Optionally, the air unit further includes a first seal disposed between the inner peripheral surface of the first plate portion and the first peripheral wall.

[0021] The first seal is located between the inner circumferential surface of the first plate and the first peripheral wall, which allows air to form a thicker air cushion in the ballast water tank, further reducing the probability of carbon dioxide being cooled by water and improving the drainage efficiency of the air and carbon dioxide linkage drainage device.

[0022] Optionally, the first plate portion further includes a first groove, which is disposed on the outer peripheral surface of the first plate portion. The first groove is annular and extends circumferentially along the first plate portion, and a first seal is disposed in the first groove.

[0023] The first groove is annular and extends circumferentially along the first plate. The first seal is disposed in the first groove, which provides a stable installation position for the first seal, ensuring that the first seal can fit tightly between the first plate and the first peripheral wall. This effectively prevents air located between the first plate and the first bottom wall from entering between the first plate and the second bottom wall, forming a thicker air cushion in the ballast water tank, further reducing the probability of carbon dioxide cooling upon contact with water, and improving the stability and reliability of the air and carbon dioxide linkage drainage device.

[0024] Optionally, the air unit also includes a pressure detection unit and a control unit, the control unit being connected to the pressure detection unit and the first drive unit respectively, and the pressure detection unit being located at the first outlet.

[0025] The control unit is connected to the pressure detection unit and the first drive unit respectively. The pressure detection unit is located at the first outlet and enables the air-carbon dioxide linkage drainage device to adjust the position of the first plate according to the air pressure value at the first outlet, thereby changing the air pressure value in the second storage chamber, allowing more water to be discharged from the ballast water tank, forming a thicker air cushion in the ballast water tank, further reducing the probability of carbon dioxide cooling when it comes into contact with water, and improving the drainage efficiency of the air-carbon dioxide linkage drainage device.

[0026] Optionally, the air and carbon dioxide linked drainage device includes multiple power unit groups and multiple pressure reducing units, with each power unit group corresponding to a different pressure reducing unit. Each power unit group includes multiple power units, and the first storage chamber of each power unit group can be selectively connected to the pressure reducing chamber of the corresponding pressure reducing unit.

[0027] The first storage chamber of each power unit group can be selectively connected to the decompression chamber of the corresponding decompression unit. When the underwater vehicle needs to surface, carbon dioxide can be allowed to enter the ballast water tank, and then the water can be discharged, thereby improving the drainage efficiency of the air and carbon dioxide linked drainage device.

[0028] Optionally, the air-carbon dioxide linked drainage device also includes a second heating source, which is located in the decompression chamber.

[0029] The second heating source is located in the pressure-reducing chamber, which can heat the air or carbon dioxide in the pressure-reducing chamber, reduce the temperature drop of the air or carbon dioxide when it comes into contact with water, and improve the operating efficiency of the air and carbon dioxide linkage drainage device.

[0030] Optionally, the second heating source is constructed as a heating sheet, which is attached to the inner wall of the decompression chamber.

[0031] The heating sheet is attached to the inner wall of the decompression chamber, which can reduce the space occupied by the second heating source in the decompression chamber and reduce the impact of the second heating source on the flow of air or carbon dioxide.

[0032] Optionally, the multiple power unit groups include a first power unit group and a second power unit group. The multiple power units in the first power unit group are arranged sequentially along a second direction, and the multiple power units in the second power unit group are arranged sequentially along a third direction. The second direction is parallel to the third direction.

[0033] The second direction is parallel to the third direction, and the first and second power unit groups are set at intervals. In this way, if multiple power unit groups need to be attached to a certain component of the underwater vehicle, the space utilization rate of the underwater vehicle can be improved.

[0034] Optionally, the plurality of pressure reducing units include a first pressure reducing unit and a second pressure reducing unit. The first storage chamber of the first power unit group is optionally connected to the pressure reducing chamber of the first pressure reducing unit, and the pressure reducing chamber of the second pressure reducing unit is optionally connected to the first storage chamber of the second power unit group. The first pressure reducing unit is configured as a first pressure reducing pipeline, and the second pressure reducing unit is configured as a second pressure reducing pipeline. The first pressure reducing pipeline extends along a second direction, and the second pressure reducing pipeline extends along a third direction.

[0035] The first pressure relief pipe extends along the second direction, and the second pressure relief pipe extends along the third direction. This allows the first and second pressure relief pipes to be installed more closely to the underwater vehicle, making the underwater vehicle's structure more compact and improving its space utilization.

[0036] Optionally, the pressure-reducing chambers of the multiple pressure-reducing units are interconnected, and the first air inlet of the flow guiding assembly is connected to at least one of the multiple pressure-reducing chambers.

[0037] The decompression chambers of multiple decompression units are interconnected, and the first air inlet of the flow guiding assembly is connected to at least one of the multiple decompression chambers. On the one hand, parallel decompression can improve decompression efficiency, and on the other hand, it can reduce the manufacturing cost of underwater vehicles.

Detailed Implementation

[0054] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0055] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0056] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0057] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0058] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

[0059] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0060] With the maturity and development of underwater navigation technology, underwater vehicles need to drain water during the ascent process. For example, when an underwater vehicle experiences unexpected situations such as rudder jamming, water ingress, or loss of depth, some of the stored seawater can be quickly discharged in a short period of time to provide positive buoyancy, thereby enabling the underwater vehicle to safely ascend.

[0061] The main differences lie in the drainage methods used by underwater vehicles. Compressed air drainage typically employs either compressed air or high-temperature gas drainage. Compressed air drainage involves pre-compressing and storing air in high-pressure air cylinders. When needed, a valve on the pipeline connecting the air cylinder to the water tank is opened, introducing high-pressure air into the water tank to drain the seawater. High-temperature gas drainage systems seal solid agents in a gas generator. When needed, an electrical signal ignites the agent, causing a chemical reaction that generates high-temperature gas, which is then injected into the water tank to drain the seawater. As the operating depth of underwater vehicles increases, compressed air drainage becomes significantly affected by back pressure, resulting in a substantial decrease in drainage capacity. High-temperature gas drainage is prone to secondary combustion, posing a safety hazard. Directly draining water from ballast tanks using pushers or similar devices is also problematic, as the high underwater pressure places a significant strain on the pushers, potentially leading to fatigue damage and breakage. Compressed air and water in the ballast tank form an air cushion. Then, liquid carbon dioxide is converted into gas to drain the water. The extremely high pressure during the carbon dioxide conversion process drains the water from the ballast tank, thus avoiding direct contact between carbon dioxide and water for cooling.

[0062] However, in related technologies, the temperature decreases during the air release process and when it comes into contact with water, causing the air volume to shrink and reducing the drainage capacity of the air-carbon dioxide linkage drainage device.

[0063] In view of this, this application proposes a drainage device that links air and carbon dioxide, which includes a power unit, an air unit, a pressure reducing unit, and a flow guiding component.

[0064] The power unit has a first storage chamber for storing liquid carbon dioxide, the air unit has a second storage chamber for storing high-pressure air, the decompression unit has a decompression chamber, and both decompression chambers can be selectively connected to the first and second storage chambers. The flow guiding assembly has a first air inlet and a first air outlet, the first air inlet being connected to the decompression chamber and the first air outlet being connected to the ballast water tank. The second storage chamber is provided with a first heating source, which is adapted to generate heat after receiving a signal to heat the air stored in the second storage chamber.

[0065] In the above scheme, a first heating source is provided in the second storage chamber. The first heating source is adapted to generate heat after receiving a signal to heat the air stored in the second storage chamber. In this way, when the air and carbon dioxide linkage drainage device is running, on the one hand, the first heating source can raise the air temperature in the second storage chamber and expand the air volume, thereby enabling more water to be discharged from the ballast water tank. On the other hand, the first heating source can also maintain the air temperature at the raised temperature, reducing the probability of the air shrinking when it encounters water, thus improving the drainage efficiency and drainage performance of the air and carbon dioxide linkage drainage device.

[0066] The first storage chamber of the power unit disclosed in this application embodiment can store liquid carbon dioxide. The liquid carbon dioxide can be excited by a heating element or an excitation element, and then the liquid carbon dioxide is converted into supercritical gaseous carbon dioxide, thereby generating a powerful ultra-high pressure to discharge the water in the ballast water tank.

[0067] For ease of explanation, the following embodiments will be described using an air and carbon dioxide linked drainage device as an example.

[0069] Please refer to Figures 1 to 4In this embodiment, the air and carbon dioxide linked drainage device 100 includes a power unit 113, an air unit 120, a pressure reducing unit 130, and a flow guiding assembly 140. The power unit 113 has a first storage chamber 114 for storing liquid carbon dioxide. The air unit 120 has a second storage chamber 121 for storing high-pressure air. The pressure reducing unit 130 has a pressure reducing chamber 133, which can be selectively connected to the first storage chamber 114 and the second storage chamber 121. The flow guiding assembly 140 has a first air inlet 141 and a first air outlet 142. The first air inlet 141 is connected to the pressure reducing chamber 133, and the first air outlet 142 is connected to the ballast water tank 150. A first heating source 160 is provided in the second storage chamber 121. The first heating source 160 is adapted to generate heat after receiving a signal to heat the air stored in the second storage chamber 121.

[0070] The air-carbon dioxide linked drainage device 100 includes a power unit 113. Under compression by the power unit 113, the carbon dioxide is in a liquid state within a first storage chamber 114, where it is stored. An air unit 120 includes a second storage chamber 121 for storing high-pressure air, which can be in a gaseous state within the second storage chamber 121. A pressure-reducing unit 130 has a pressure-reducing chamber 133. Exemplarily, the pressure-reducing chamber 133 can be constructed as a hollow, thin-walled cylinder. The pressure-reducing chamber 133 can selectively communicate with the first storage chamber 114 and the second storage chamber 121. Carbon dioxide in the first storage chamber 114 can enter the pressure-reducing chamber 133. As the carbon dioxide enters the pressure-reducing chamber 133, its pressure decreases, allowing it to expand more fully and increasing its volume, thereby enhancing the drainage capacity of the air-carbon dioxide linked drainage device 100. The high-pressure air stored in the second storage chamber 121 can also enter the depressurization chamber 133. After the air enters the depressurization chamber 133, the pressure will decrease, and the air will expand more fully, increasing its volume and thus enhancing the drainage capacity of the air-carbon dioxide linked drainage device 100. The flow guiding assembly 140 has a first air inlet 141 and a first air outlet 142. After air or carbon dioxide enters the depressurization chamber 133, it then enters the first air inlet 141 of the flow guiding assembly 140 from the depressurization chamber 133, and exits the flow guiding assembly 140 from the first air outlet 142, and then enters the ballast water tank 150. The ballast water tank 150 stores water, and the air or carbon dioxide entering the ballast water tank 150 will discharge the water in the ballast water tank 150.

[0071] Because supercritical carbon dioxide cools, increases in density, and shrinks in volume when it comes into contact with water, its ability to dissipate water is weakened. Therefore, the high-pressure air stored in the second storage chamber 121 can be discharged first, followed by the carbon dioxide, to avoid direct contact between the carbon dioxide and water. For example, the high-pressure air in the second storage chamber 121 of the air unit 120 is first discharged and enters the depressurization chamber 133, then flows from the depressurization chamber 133 into the flow guide assembly 140, and after passing through the flow guide assembly 140, it enters the ballast water tank 150, discharging some of the water in the ballast water tank 150. An air cushion is then formed in the ballast water tank 150, and the carbon dioxide in the first storage chamber 114 is released, allowing the carbon dioxide in the first storage chamber 114 to enter the ballast water tank 150, thereby discharging the water in the ballast water tank 150. Carbon dioxide is liquid under certain pressure and temperature, has a high density, and is easy to store. When carbon dioxide is heated and pressurized, it can be rapidly converted into a supercritical state, expanding its volume several times. It has a strong instantaneous work capacity and can discharge water under high water pressure.

[0072] When air stored in the second storage chamber 121 is discharged into the ballast water tank 150, the air comes into direct contact with the water in the ballast water tank 150. During the air release process and upon contact with the water, the air temperature decreases, and its volume contracts, reducing the amount of water discharged from the ballast water tank 150. Therefore, a first heating source 160 is installed in the second storage chamber 121. The first heating source 160 is adapted to generate heat upon receiving a signal to heat the air stored in the second storage chamber 121. This causes the air to expand due to heat, increasing its volume. When the air is discharged into the ballast water tank 150, the larger volume of air allows for the discharge of more water, thereby improving the efficiency and performance of the air-carbon dioxide linked drainage device 100. Furthermore, the heat generated by the first heating source 160 upon receiving a signal continuously heats the air, maintaining its temperature within a roughly balanced range. This maintains the air's volume expansion, reduces the likelihood of the air cooling and contracting upon contact with water, and further improves the efficiency of the air-carbon dioxide linked drainage device 100.

[0073] Furthermore, the air-carbon dioxide linked drainage device 100 combines liquid carbon dioxide and high-pressure air as power sources. Liquid carbon dioxide rapidly enters a supercritical state when heated, providing powerful propulsion. For large underwater vehicles 1000, when located deep on the seabed, the ballast tank 150 experiences significant water pressure. Without the powerful propulsion of carbon dioxide, it would be difficult to expel the water from the ballast tank 150. High-pressure air can also serve as auxiliary power, ensuring the continuity and stability of drainage. The harmless carbon dioxide gas, when released into the atmosphere, will not pollute the environment. Simultaneously, the device design reduces direct wastewater discharge, helping to protect water resources and the ecological environment. Furthermore, due to its modular design and high-quality material manufacturing, the device boasts high reliability and durability, enabling long-term stable operation and meeting various drainage needs.

[0074] Specifically, a first heating source 160 is provided in the second storage chamber 121. The first heating source 160 is adapted to generate heat after receiving a signal to heat the air stored in the second storage chamber 121. In this way, when the air and carbon dioxide linked drainage device 100 is running, on the one hand, the first heating source 160 can raise the temperature of the air in the second storage chamber 121 and expand the air volume, thereby enabling more water to be discharged from the ballast water tank 150. On the other hand, the first heating source 160 can also maintain the air temperature at the raised temperature, reducing the probability of the air shrinking when it encounters water, thus improving the drainage efficiency and drainage performance of the air and carbon dioxide linked drainage device 100.

[0075] Please refer to Figures 1 to 7 For example, the power unit 113 has a second outlet 115 from which carbon dioxide can enter the decompression chamber 133.

[0076] Please refer to Figures 1 to 8 The pressure reducing unit 130 has a first pressure reducing inlet 134 and a first pressure reducing outlet 135. The first pressure reducing inlet 134 can be connected to the first storage chamber 114 and the second storage chamber 121. Air or carbon dioxide can enter the pressure reducing chamber 133 from the first pressure reducing inlet 134. The first pressure reducing outlet 135 can be connected to the first air inlet 141 of the flow guiding assembly 140. The pressure-reduced air or carbon dioxide can exit the pressure reducing chamber 133 from the first pressure reducing outlet 135 and enter the flow guiding assembly 140.

[0077] Please refer to Figures 1 to 5 In this embodiment, the first heating source 160 is configured as an activation agent assembly, which includes an agent body and an activation unit. The activation unit is adapted to activate the agent body after receiving a signal, so that the agent body undergoes a chemical reaction and generates heat.

[0078] The activation agent component can quickly activate the agent body after receiving a signal, causing it to undergo a chemical reaction and generate a large amount of heat. This instantaneous heating capability allows the device to reach the required temperature in a short time, thereby rapidly heating the high-pressure air and improving drainage efficiency.

[0079] Compared to traditional heating elements, ignition reagent assemblies typically have a simpler structure and fewer parts, which helps reduce manufacturing and maintenance costs. Furthermore, since the reagent body and ignition unit are integrated, installation and commissioning complexity is also reduced.

[0080] The activating agent components only require a transient low-voltage electrical signal and are generally highly reliable and stable. They do not rely on electricity or other external energy sources to continuously generate heat, which means that in the event of a power failure or other emergency, the device can still maintain the drainage operation by relying on the heat provided by the agent components, provided only by a low-voltage backup power supply.

[0081] Specifically, the excitation unit is adapted to excite the drug body after receiving a signal, so that the drug body undergoes a chemical reaction and generates heat. This can improve the drainage efficiency of the air-carbon dioxide linked drainage device 100 and reduce the probability of the air-carbon dioxide linked drainage device 100 malfunctioning.

[0082] Please refer to Figures 1 to 5 In this embodiment, the first heating source 160 is configured as a PTC heating component.

[0083] The PTC heating element uses positive temperature coefficient thermistor (PTC) material as its core component. It has the characteristic that the resistance increases with the temperature. This characteristic enables the PTC heating element to automatically limit the temperature during the heating process and automatically stabilize at the set temperature. This achieves efficient heating and precise temperature control. This automatic temperature control function helps to maintain stable heating of the air in the air-carbon dioxide linked drainage device 100 and improves drainage efficiency.

[0084] PTC heating elements do not produce open flames during heating and do not exhibit the surface "red-hot" phenomenon common in electric heating tube heaters, thus greatly reducing safety hazards such as fire and burns. Furthermore, PTC heating elements possess excellent insulation and electrical safety performance, enabling stable operation in various harsh environments and ensuring the safety and reliability of the air-carbon dioxide linked drainage device 100%.

[0085] The power of the PTC heating element can be automatically adjusted according to changes in the air temperature of the second storage chamber 121, enabling the air-carbon dioxide linked drainage device 100 to adapt to different operating environments under varying temperature conditions. Furthermore, the PTC heating element has wide voltage adaptability, maintaining stable heating performance within different voltage fluctuation ranges.

[0086] Specifically, the first heating source 160 is configured as a PTC heating component, which can heat efficiently and control the temperature precisely. This automatic temperature control function helps to maintain stable heating of the air in the air-carbon dioxide linked drainage device 100 and improve drainage efficiency.

[0087] Please refer to Figure 5 In this embodiment, the air and carbon dioxide linked drainage device 100 further includes a heat insulation layer 170, which covers the inner wall of the second storage chamber 121 to keep the air in the second storage chamber 121 warm.

[0088] The air-carbon dioxide linked drainage device 100 also includes an insulation layer 170, which covers the inner wall of the second storage chamber 121. This means the insulation layer 170 does not obstruct or affect airflow within the second storage chamber 121. After the first heating source 160 heats the air in the second storage chamber 121, the air-carbon dioxide linked drainage device 100 is typically located outside the underwater vehicle 1000. Consequently, the outer wall of the second storage chamber 121 is in direct contact with seawater, making it easier for the air inside the second storage chamber 121 to cool down, thus causing volume contraction.

[0089] An insulation layer 170 is provided in the second storage chamber 121 and is located on the inner side wall of the second storage chamber 121. This insulation layer 170 can keep the air in the second storage chamber 121 warm, reduce the chance of air cooling, and improve the operating efficiency and performance of the air and carbon dioxide linkage drainage device 100.

[0090] Please refer to Figure 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 133. The air unit 120 also includes a bursting diaphragm 123, which is disposed at the first outlet 122 and is configured to tear when the pressure in the second storage chamber 121 reaches a first preset value.

[0091] The air unit 120 has a first outlet 122, which is connected to the second storage chamber 121 and the depressurization chamber 133. The air stored in the second storage chamber 121 can exit the second storage chamber 121 from the first outlet 122 and enter the depressurization chamber 133. The depressurization chamber 133 is connected to the second storage chamber 121 through the first outlet 122.

[0092] The air unit 120 also includes a bursting diaphragm 123, which is disposed at the first outlet 122. When the air pressure in the second storage chamber 121 reaches a first preset value, the bursting diaphragm 123 will tear. That is, after the air pressure reaches the first preset value, the air stored in the second storage chamber 121 can break the bursting diaphragm 123, thereby allowing the air to enter the depressurization chamber 133 from the second storage chamber 121.

[0093] Specifically, the rupture diaphragm 123, as a pressure-sensitive element, can automatically tear when the pressure in the second storage chamber 121 reaches a preset safety limit, thereby releasing excessive pressure. This design effectively prevents equipment damage or safety accidents caused by excessive pressure, and optimizes the working pressure range of the air and carbon dioxide linked drainage device 100, thereby improving drainage efficiency. When the pressure reaches the first preset value, the rupture diaphragm 123 automatically tears, allowing high-pressure air to smoothly enter the pressure-reducing chamber 133 and drive the drainage process.

[0094] Please refer to Figure 5 In this 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 edges of the first bottom wall 125 and 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 127. Along the first direction X, the outer peripheral surface of the first plate portion 127 is slidably connected to the inner peripheral surface of the first peripheral wall 124.

[0095] The air unit 120 includes a first peripheral wall 124, a first bottom wall 125, and a second bottom wall 126. The first bottom wall 125 and the second bottom wall 126 are arranged opposite to each other along the first direction X. The two ends of the first peripheral wall 124 are respectively connected to the outer periphery of the first bottom wall 125 and the outer periphery of the second bottom wall 126. The first outlet 122 is located on the first bottom wall 125. That is to say, the first bottom wall 125 is closer to the decompression chamber 133, and the second bottom wall 126 is farther from the decompression chamber 133. Since not all the air inside the air unit 120 can be discharged into the ballast water tank 150 for drainage during the air release process, a first plate 127 can be provided inside the air unit 120. The outer peripheral surface of the first plate 127 is slidably connected to the inner peripheral surface of the first peripheral wall 124. That is, along the first direction X, the first plate 127 and the first peripheral wall 124 can undergo relative displacement, the volume of the second storage chamber 121 decreases, and the first plate 127 can push the remaining air in the air bottle to the ballast water tank 150, thereby improving the utilization efficiency of the air inside the air unit 120.

[0096] Specifically, the air unit 120 also includes a first plate portion 127. Along the first direction X, the outer peripheral surface of the first plate portion 127 is slidably connected to the inner peripheral surface of the first peripheral wall 124, which can improve the utilization efficiency of air in the air bottle, allow the ballast water tank 150 to discharge more water, form a thicker air cushion, further reduce the probability of carbon dioxide contacting water and cooling, and improve the operating efficiency and reliability of the air and carbon dioxide linked drainage device 100.

[0097] Please refer to Figure 5 In this embodiment, the air unit 120 further includes a first driving member 180, which is disposed on the second bottom wall 126, and the power output end of the first driving member 180 is connected to the first plate portion 127.

[0098] The air unit 120 includes a first drive member 180, which can be configured as a drive motor. The first drive member 180 is disposed on the second bottom wall 126 and has a power output end. The power output end of the first drive member 180 is connected to the first plate portion 127 and the first drive member 180 can control the first plate portion 127 to move in the first direction X.

[0099] Specifically, the power output end of the first drive member 180 is connected to the first plate 127. The introduction of the first drive member 180 provides an additional power source for the air unit 120. By precisely controlling the operating speed and force of the first drive member 180, and thus controlling the movement of the first plate 127, fine adjustment of parameters such as airflow and pressure inside the air unit 120 can be achieved, thereby improving the operating efficiency of the air and carbon dioxide linkage drainage device 100.

[0100] Please refer to Figure 5 In this embodiment, the air unit 120 further includes a first sealing member 190, which is disposed between the inner peripheral surface of the first plate portion 127 and the first peripheral wall 124.

[0101] The first seal 190 is disposed between the inner circumferential surface of the first plate portion 127 and the first peripheral wall 124. The first seal 190 can play a sealing role. When the first plate portion 127 moves along the first direction X, the first seal 190 can prevent the air located between the first plate portion 127 and the first bottom wall 125 from entering the space between the first plate portion 127 and the second bottom wall 126. This can increase the air pressure in the air unit 120, force the air in the air unit 120 into the ballast water tank 150, thereby forming a thicker air cushion, discharging more water from the ballast water tank 150, further reducing the volume shrinkage caused by carbon dioxide cooling, and improving the drainage capacity of the air and carbon dioxide linked drainage device 100. Understandably, the material of the first seal 190 can be nitrile rubber (NBR), silicone rubber, or fluororubber. Nitrile rubber (NBR) has good oil resistance and is suitable for sealing applications that come into contact with oily media. Silicone rubber has good high-temperature 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.

[0102] Specifically, the first seal 190 is disposed between the inner circumferential surface of the first plate portion 127 and the first peripheral wall 124, which enables air to form a thicker air cushion in the ballast water tank 150, further reducing the probability of carbon dioxide being cooled by water and improving the drainage efficiency of the air and carbon dioxide linkage drainage device 100.

[0103] Please refer to Figure 6 In this embodiment, the first plate portion 127 further includes a first groove 128, which is disposed on the outer peripheral surface of the first plate portion 127. The first groove 128 is annular and extends circumferentially along the first plate portion 127. The first sealing member 190 is disposed in the first groove 128.

[0104] The first plate portion 127 also includes a first groove 128. The opening of the first groove 128 faces the first peripheral wall 124. The first groove 128 is disposed on the outer peripheral surface of the first plate portion 127. The first groove 128 is annular in shape and extends circumferentially along the first plate portion 127. It can be understood that the opening of the first groove 128 is approximately perpendicular to the first direction X. The first seal 190 can be disposed between the first groove 128 and the first peripheral wall 124. The first groove 128 provides a stable mounting position for the first seal 190, ensuring that the first seal 190 can fit tightly between the first plate portion 127 and the first peripheral wall 124, effectively preventing air located between the first plate portion 127 and the first bottom wall 125 from entering between the first plate portion 127 and the second bottom wall 126. Moreover, the first seal 190 is installed in the first groove 128, which can increase the contact area between the first seal 190 and the first plate portion 127 and the first peripheral wall 124, thereby improving the reliability and stability of the seal. Furthermore, the design of the first groove 128 makes the installation of the first seal 190 more convenient and quick, eliminating the need for additional fixing devices or adhesives, thus reducing installation difficulty and cost. The presence of the first groove 128 can, to a certain extent, enhance the structural strength of the first plate 127, making it more resistant to external pressure or impact, and improving the overall stability of the air and carbon dioxide linked drainage device 100.

[0105] Specifically, the first groove 128 is annular and extends circumferentially along the first plate portion 127. The first seal 190 is disposed in the first groove 128, which provides a stable installation position for the first seal 190, ensuring that the first seal 190 can fit tightly between the first plate portion 127 and the first peripheral wall 124. This effectively prevents air located between the first plate portion 127 and the first bottom wall 125 from entering between the first plate portion 127 and the second bottom wall 126, thus forming a thicker air cushion in the ballast water tank 150. This further reduces the probability of carbon dioxide cooling upon contact with water and improves the stability and reliability of the air and carbon dioxide linked drainage device 100.

[0106] Please refer to Figures 1 to 6 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 drive unit 180, respectively. The pressure detection unit is located at the first outlet 122.

[0107] The air unit 120 may further include a pressure detection unit and a control unit. The pressure detection unit detects the air pressure inside the second storage chamber 121. The control unit is connected to both the pressure detection unit and the first drive member 180. The pressure detection unit sends the detected air pressure value to the control unit. The control unit controls the first drive member 180 based on the data detected by the pressure detection unit, controlling the first plate portion 127 to move along the first direction X and toward the first bottom wall 125. For example, when the air pressure value is below a first threshold, the control unit controls the first drive member 180 to move the first plate portion 127; when the air pressure value is above the first threshold, the control unit does not control the first drive member 180. The pressure detection unit may be located at the first outlet 122. Since air is discharged from the second storage chamber 121 through the first outlet 122, a pressure detection unit located at the first outlet 122 can more accurately measure the air pressure value.

[0108] Specifically, the control unit is connected to the pressure detection unit and the first drive unit 180 respectively. The pressure detection unit is located at the first outlet 122. The air-carbon dioxide linkage drainage device 100 can adjust the position of the first plate 127 according to the air pressure value at the first outlet 122, thereby changing the air pressure value in the second storage chamber 121, so that more water in the ballast water tank 150 is discharged, forming a thicker air cushion in the ballast water tank 150, further reducing the probability of carbon dioxide cooling when it comes into contact with water, and improving the drainage efficiency of the air-carbon dioxide linkage drainage device 100.

[0109] Please refer to Figures 1 to 7 In this embodiment, the air and carbon dioxide linked drainage device 100 includes multiple power unit groups 110 and multiple pressure reducing units 130. The multiple power unit groups 110 correspond one-to-one with the multiple pressure reducing units 130. Each power unit group 110 includes multiple power units 113. The first storage chamber 114 of each power unit group 110 can be selectively connected to the pressure reducing chamber 133 of the corresponding pressure reducing unit 130.

[0110] The air-carbon dioxide linked drainage device 100 includes multiple power unit groups 110, which allows the air-carbon dioxide linked drainage device 100 to flexibly adjust the power output according to the drainage demand. When a large amount of drainage is required from the ballast water tank 150, more power unit groups 110 can be activated, thereby improving the drainage efficiency. Multiple power unit groups 110 and multiple pressure reducing units 130 correspond one-to-one. That is, carbon dioxide from multiple power unit groups 110 can exit the power unit group 110 and then enter the pressure reducing chamber 133. Each power unit group 110 includes multiple power units 113. When it is necessary to discharge carbon dioxide from the first storage chamber 114, the first storage chamber 114 of each power unit 113 can be connected to the pressure reducing chamber 133. Then, carbon dioxide exits the first storage chamber 114 and enters the pressure reducing chamber 133. For example, a rupture diaphragm 123 can be set between the pressure reducing chamber 133 and the first storage chamber 114. When the pressure value of carbon dioxide exceeds a certain threshold, carbon dioxide will break through the rupture diaphragm 123 and enter the pressure reducing chamber 133 from the first storage chamber 114.

[0111] Specifically, the first storage chamber 114 of each power unit group 110 can be selectively connected to the decompression chamber 133 of the corresponding decompression unit 130. When the underwater vehicle 1000 needs to surface, carbon dioxide can enter the ballast water tank 150 and then the water can be discharged, thereby improving the drainage efficiency of the air and carbon dioxide linked drainage device 100.

[0112] Please refer to Figures 1 to 8 In this embodiment, the air and carbon dioxide linked drainage device 100 further includes a second heating source 200, which is disposed in the pressure reducing chamber 133.

[0113] The second heating source 200 is installed in the pressure reducing chamber 133, which can heat the air or carbon dioxide in the pressure reducing chamber 133, reduce the temperature drop of the air or carbon dioxide when it comes into contact with water, and improve the operating efficiency of the air and carbon dioxide linked drainage device 100.

[0114] Please refer to Figures 1 to 8 In this embodiment, the second heating source 200 is constructed as a heating sheet, which is attached to the inner wall of the decompression chamber 133.

[0115] The heating sheet is attached to the inner wall of the decompression chamber 133, which can reduce the space occupied by the second heating source 200 in the decompression chamber 133 and reduce the impact of the second heating source 200 on the flow of air or carbon dioxide.

[0116] Please refer to Figures 1 to 8In this embodiment, the plurality of power unit groups 110 include a first power unit group 111 and a second power unit group 112. The plurality of power units 113 in the first power unit group 111 are arranged sequentially along a second direction, and the plurality of power units 113 in the second power unit group 112 are arranged sequentially along a third direction. The second direction is parallel to the third direction.

[0117] The multiple power unit groups 110 include a first power unit group 111 and a second power unit group 112. The first power unit group 111 includes multiple power units 113. The multiple power units 113 of the first power unit group 111 are arranged sequentially along a second direction, while the multiple power units 113 of the second power unit group 112 are arranged sequentially along a third direction. The second direction and the third direction are parallel. It can be understood that the first power unit group 111 and the second power unit group 112 are arranged alternately. In this way, if multiple power unit groups 110 need to be attached to a certain component of the underwater vehicle 1000, the space utilization rate of the underwater vehicle 1000 can be improved.

[0118] Please refer to Figures 1 to 8 In this embodiment, the plurality of pressure reducing units 130 include a first pressure reducing unit and a second pressure reducing unit. The first storage chamber 114 of the first power unit group 111 is optionally connected to the pressure reducing chamber 133 of the first pressure reducing unit. The pressure reducing chamber 133 of the second pressure reducing unit is optionally connected to the first storage chamber 114 of the second power unit group 112. The first pressure reducing unit is configured as a first pressure reducing pipeline 131, and the second pressure reducing unit is configured as a second pressure reducing pipeline 132. The first pressure reducing pipeline 131 extends along a second direction, and the second pressure reducing pipeline 132 extends along a third direction.

[0119] Multiple pressure-reducing units 130 include a first pressure-reducing unit and a second pressure-reducing unit, which can be arranged at intervals. The first storage chamber 114 of the first power unit group 111 can be connected to the pressure-reducing chamber 133 of the first pressure-reducing unit. Liquid carbon dioxide can be heated in the first storage chamber 114, turning it into supercritical carbon dioxide, and then enters the pressure-reducing chamber 133 of the first pressure-reducing unit. Similarly, the pressure-reducing chamber 133 of the second pressure-reducing unit can be selectively connected to the first storage chamber 114 of the second power unit group 112, and carbon dioxide in the second storage chamber 121 can enter the pressure-reducing chamber 133 from the second storage chamber 121.

[0120] The first pressure reducing unit is constructed as a first pressure reducing pipeline 131, and multiple pressure reducing units 130 of the first pressure reducing unit are all connected to the first pressure reducing pipeline 131. The second pressure reducing unit is constructed as a second pressure reducing pipeline 132, and multiple pressure reducing units 130 of the second pressure reducing unit are all connected to the second pressure reducing pipeline 132. The first pressure reducing pipeline 131 extends along a second direction, and the second pressure reducing pipeline 132 extends along a third direction. The first pressure reducing pipeline 131 and the second pressure reducing pipeline 132 are spaced apart.

[0121] Specifically, the first pressure relief pipe 131 extends along the second direction, and the second pressure relief pipe 132 extends along the third direction. This allows the first pressure relief pipe 131 and the second pressure relief pipe 132 to be more closely fitted to the underwater vehicle 1000, making the structure of the underwater vehicle 1000 more compact and improving the space utilization of the underwater vehicle 1000.

[0122] Please refer to Figures 1 to 8 In this embodiment, the number of power units 113 in the first power unit group 111 is less than the number of power units 113 in the second power unit group 112, and the inner diameter of the first pressure reducing pipeline 131 is less than the inner diameter of the second pressure reducing pipeline 132.

[0123] The number of power units 113 in the first power unit group 111 is less than the number of power units 113 in the second power unit group 112. Therefore, the pressure of carbon dioxide ejected from the first power unit group 111 will be weaker than the pressure of carbon dioxide ejected from the second power unit group 112. As a result, the inner diameter of the first pressure reducing pipe 131 can be smaller than the inner diameter of the second pressure reducing pipe 132. This ensures that after the pressure reducing unit 130 reduces the pressure of the first power unit group 111 and the second power unit group 112, the pressure of carbon dioxide ejected from the guide component 140 is relatively balanced, thereby improving the drainage stability and reliability of the air and carbon dioxide linkage drainage device 100.

[0124] In addition, the carbon dioxide ejected from the first power unit group 111 flows through the decompression chamber 133 of the first decompression pipeline 131 and the decompression chamber 133 of the second decompression pipeline 132, and then enters the ballast water tank 150 through the flow guide assembly 140. Meanwhile, the carbon dioxide ejected from the second power unit group 112 can directly enter the flow guide assembly 140 from the decompression chamber 133 of the second decompression pipeline 132, and then enter the ballast water tank 150. As a result, the inner diameter of the first decompression pipeline 131 of the first power unit 113 can be smaller than the inner diameter of the second decompression pipeline 132, thereby reducing the manufacturing cost of the air and carbon dioxide linkage drainage device 100.

[0125] Specifically, the inner diameter of the first pressure-reducing pipe 131 is smaller than the inner diameter of the second pressure-reducing pipe 132. This can improve the stability and reliability of the drainage of the air-carbon dioxide linked drainage device 100 on the one hand, and reduce the manufacturing cost of the air-carbon dioxide linked drainage device 100 on the other hand.

[0126] Please refer to Figures 1 to 8 In this embodiment, the pressure-reducing chambers 133 of the plurality of pressure-reducing units 130 are interconnected, and the first air inlet 141 of the flow guide assembly 140 is connected to at least one of the plurality of pressure-reducing chambers 133.

[0127] Because the pressure-reducing chambers 133 of the multiple pressure-reducing units 130 are interconnected, they can share and balance the pressure. This helps to achieve a more uniform and stable pressure distribution throughout the system, reducing pressure fluctuations and instability.

[0128] When the first air inlet 141 of the flow guide assembly 140 is connected to at least one of the multiple pressure-reducing chambers 133, air and carbon dioxide, after entering the pressure-reducing chamber 133, can enter the flow guide assembly 140 through the first air inlet 141 and then enter the ballast water tank 150. Thus, even if the air-carbon dioxide linked drainage device 100 needs to increase its drainage volume or capacity, a power unit 113 can be added, and the added power unit 113 can be connected to the pressure-reducing chamber 133, eliminating the need for multiple flow guide assemblies 140 and significantly reducing the manufacturing cost of the air-carbon dioxide linked drainage device 100. Furthermore, by using multiple pressure-reducing units 130 in parallel for pressure reduction, this parallel pressure reduction method can significantly improve pressure reduction efficiency, allowing the gas to reach the required pressure level more quickly, while also reducing the individual manufacturing cost.

[0129] Specifically, the decompression chambers 133 of the multiple decompression units 130 are connected to each other, and the first air inlet 141 of the flow guide assembly 140 is connected to at least one of the multiple decompression chambers 133. On the one hand, parallel decompression can improve decompression efficiency, and on the other hand, it can reduce the manufacturing cost of the underwater vehicle 1000.

[0130] Please refer to Figures 1 to 9 This application also provides an underwater vehicle 1000, including a drainage device 100 that links air and carbon dioxide according to any one of the embodiments of this application.

[0131] In some embodiments, air or carbon dioxide can enter the ballast water tank 150 from the air and carbon dioxide linked drainage device 100, and then the water in the ballast water tank 150 is discharged from the underwater vehicle 1000 through the first pipe 210, thereby reducing the weight of the underwater vehicle 1000.

[0132] Please refer to Figures 9 to 11In some embodiments, when the underwater vehicle 1000 needs to ascend quickly and the air-carbon dioxide linked drainage device 100 needs to drain water quickly, the control unit, upon receiving the rapid ascent signal from the underwater vehicle 1000, can control the first drive member 180 to accelerate the position of the first plate 127 according to the ascent requirement of the underwater vehicle 1000, so that more air enters the ballast tank 150 in a shorter time, causing the underwater vehicle 1000 to discharge more water, thereby enabling the underwater vehicle 1000 to ascend quickly.

[0133] Please refer to Figures 9 to 11 In some embodiments, a flow guiding component 140 is provided between the air-carbon dioxide linked drainage device 100 and the ballast water tank 150. One end of the flow guiding component 140 is connected to the air-carbon dioxide linked drainage device 100, and the other end is connected to the ballast water tank 150. Air or carbon dioxide can enter the ballast water tank 150 from the air-carbon dioxide linked drainage device 100 through the flow guiding component 140. A first exhaust valve 260 may be provided on the flow guiding component 140. The first exhaust valve 260 is used to control the exhaust volume and exhaust speed of the air-carbon dioxide linked drainage device 100 per unit time, that is, the gas flow rate and velocity. For example, the first exhaust valve 260 can control the surfacing speed of the underwater vehicle 1000 when it is navigating underwater, which requires precise control. The first exhaust valve 260 is connected to the control unit. The control unit can control the opening and closing degree of the first exhaust valve 260 on the flow guide assembly 140, thereby controlling the flow rate and velocity of the gas through the flow guide assembly 140. For example, when the underwater vehicle 1000 needs to ascend quickly, for example, at an ascending speed of 10 m / s, the first exhaust valve 260 can be fully opened, allowing the gas (carbon dioxide or air) to pass through the flow guide assembly 140 at the maximum flow rate and velocity and enter the ballast tank 150, thereby discharging the water from the ballast tank 150. When the underwater vehicle 1000 needs to ascend at a moderate speed, for example, at an ascending speed of 5 m / s, the first exhaust valve 260 can be in a semi-open state, allowing the gas to flow out at a corresponding flow rate and velocity per unit time, thereby precisely controlling the ascent of the underwater vehicle 1000.

[0134] Please refer to Figures 9 to 11In some embodiments, the underwater vehicle 1000 also includes a gas recovery device 270, which is optionally connected to an air and carbon dioxide-linked drainage device 100. When the underwater vehicle 1000 is buoyant, the gas recovery device 270 is not connected to the air and carbon dioxide-linked drainage device 100. When the underwater vehicle 1000 needs to sink, the gas recovery device 270 is connected to the air and carbon dioxide-linked drainage device 100. Air and carbon dioxide in the ballast tank 150 flow into the gas recovery device 270, and the ballast tank 150 is refilled with water, thereby increasing the weight of the underwater vehicle 1000 so that the weight of the underwater vehicle 1000 is greater than the buoyancy, thereby allowing the underwater vehicle 1000 to sink.

[0135] Please refer to Figures 9 to 11 In 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 connected to the outer periphery of the third bottom wall 272 and the outer periphery of the fourth bottom wall 273, respectively. The third bottom wall 272 is provided with a third outlet 274, which communicates with the ballast water tank 150. Air or carbon dioxide from the ballast water tank 150 enters the gas recovery device 270 through the third outlet 274. It also includes a second plate 275, the outer peripheral surface of which is slidably connected to the inner peripheral surface of the second peripheral wall 271. The second plate 275 is movably disposed on the inner peripheral surface of the second peripheral wall 271. When gas enters the gas recovery device 270, the second plate 275 is controlled to move away from the third outlet 274. When the underwater vehicle 1000 needs to surface, the second plate 275 is controlled to move closer to the third outlet 274, so that the carbon dioxide and air in the gas recovery device 270 are discharged into the ballast water tank 150.

[0136] Please refer to Figures 9 to 11In some embodiments, the ballast tank 150 discharges water through the outlet of the first pipe 210. A Helmholtz resonator is arranged circumferentially along the outlet of the first pipe 210. Each Helmholtz resonator unit is made of a 316L stainless steel substrate and contains 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, converting sound energy into heat energy through viscous dissipation and thermal conduction effects. A piezoelectric ceramic sheet can be embedded in the neck of the Helmholtz resonator. A MEMS hydrophone array can be arranged at the outlet of the first pipe 210. The MEMS hydrophone is used to collect noise signals in real time and outputs an analog voltage to the corresponding piezoelectric ceramic sheet through a conversion module. The adjustment time can be less than 5 seconds. The Helmholtz resonator operates, reducing or eliminating drainage noise at the outlet of the first pipe 210.

[0137] Please refer to Figures 9 to 11 In some embodiments, the underwater vehicle 1000 can be a submarine.

[0138] Please refer to Figures 9 to 11 In some embodiments, the power unit 113 includes a third peripheral wall 280, a fifth bottom wall 281, and a sixth bottom wall 282. The power unit 113 also includes a second driving member 283 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 113 also includes a second sealing member 285 disposed between the inner peripheral surface of the third plate portion 284 and the third peripheral wall 280. The third plate portion 284 also includes a second groove 286 disposed on the third plate portion 284. The outer peripheral surface of the second groove 286 is annular and extends circumferentially along the third plate portion 284. The second seal 285 is disposed in the second groove 286. The sixth bottom wall 282 is provided with a second opening 115, which communicates with the pressure reducing chamber 133. The second drive member 283 can drive the third plate portion 284 to move toward the second opening 115, squeezing the carbon dioxide stored in the power unit 113 into the pressure reducing chamber 133, thereby allowing more water to be discharged, improving the utilization rate of carbon dioxide, and improving the drainage efficiency of the air and carbon dioxide linked drainage device 100.

[0139] In some embodiments, the air-carbon dioxide linked drainage device 100 further includes a biomimetic gill-like multilayer gas exchange membrane. The multilayer gas exchange membrane includes a base layer, a functional layer, and a protective layer. The base layer is constructed of polytetrafluoroethylene (PTFE) and a porous membrane (0.2 micrometers in pore size) to provide mechanical support. The functional layer is constructed of a lipid bilayer structure mimicking fish gill cells, embedding a recombinant aquaporin-Z to selectively block the permeation of carbon dioxide molecules. The protective layer is constructed of a silica nanocoating (50 nm thick) to prevent the adhesion of biofouling. The multilayer gas exchange membrane is movably disposed inside the ballast tank 150 and located between the water and air cushion, further reducing the probability of carbon dioxide contact with water and the probability of carbon dioxide cooling and contraction, allowing more water to be discharged from the air-carbon dioxide linked drainage device 100, thereby further improving the drainage efficiency of the air-carbon dioxide linked drainage device 100.

[0140] Please refer to Figures 1 to 12 In some embodiments, the air-carbon dioxide linked drainage device 100 further includes a first buffer plate 290, which can be disposed on the inner wall of the second pressure-reducing pipeline 132. The first buffer plate 290 has a plurality of first holes 300 extending through it along its thickness direction. Each first hole 300 includes a first end 301 and a second end 302, which are positioned opposite each other along the thickness direction of the first buffer plate 290. The radial dimension of the first end 301 is larger than that of the second end 302. The first hole 300 extends from the first end 301 to the second end 302. As the size gradually increases, air or carbon dioxide enters the first hole 300 from the second end 302, and then flows from the first end 301 to the guide assembly 140. At the moment of release, the air or carbon dioxide has a large pressure, a large impact force, and a small volume. By setting the first buffer plate 290, the air or carbon dioxide can be buffered, reducing the impact of air or carbon dioxide entering the ballast water tank 150, allowing the air and carbon dioxide to be released more fully in the second depressurization pipeline 132, increasing the volume of air or carbon dioxide, and allowing more air or carbon dioxide to enter the ballast water tank 150, thereby improving the drainage capacity of the air and carbon dioxide linked drainage device 100.
