Description

Technical Field

[0001] This application relates to the technical field of underwater vehicle drainage, and particularly relates to a drainage device and an underwater vehicle with associated air and carbon dioxide. Background Art

[0002] With the maturity and development of underwater navigation technology, an underwater vehicle needs to drain water during the process of surfacing, so as to achieve safe surfacing. Larger underwater vehicles generally use compressed air drainage or high-temperature gas drainage. Compressed air drainage uses the discharge of compressed air to drain the water in the water storage tank, while high-temperature gas drainage uses igniting a chemical agent to generate high-temperature gas, and the high-temperature gas enters the water tank to drain the water. Compressed air drainage is greatly affected by the water backpressure. 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.

[0003] An air cushion is formed by compressed air and the water in the ballast tank, and then liquid carbon dioxide is changed into a supercritical state for drainage. The ultra-high pressure during the transformation of carbon dioxide drains the water in the ballast tank, which can avoid direct contact cooling between carbon dioxide and water. However, in the related art, the temperature of the air itself decreases during the air release process and when it contacts water, resulting in the shrinkage of the air volume and reducing the drainage capacity of the drainage device with associated air and carbon dioxide. Summary of the Invention

[0004] This application provides a drainage device and an underwater vehicle with associated air and carbon dioxide, which solves the technical problem that the direct contact between air and water reduces the temperature, resulting in the shrinkage of the air volume and reducing the drainage capacity of the drainage device with associated air and carbon dioxide.

[0005] To achieve the above object, the main technical solutions adopted in this application include: In a first aspect, an embodiment of this application provides a drainage device with associated air and carbon dioxide. The drainage device with associated air and carbon dioxide includes a power unit, an air unit, a pressure reducing unit, and a diversion assembly. 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, and the pressure reducing chamber can be selectively communicated with the first storage chamber and the second storage chamber. The diversion assembly has a first air inlet and a first air outlet. The first air inlet is communicated with the pressure reducing chamber, and the first air outlet is communicated with the ballast tank. Among them, a first heating source is arranged in the second storage chamber, and the first heating source is adapted to generate heat after receiving a signal to heat the air stored in the second storage chamber.

[0006] 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 linked drainage device operates, on the one hand, the first heating source can increase the temperature of the air in the second storage chamber, causing the air volume to expand, and thus enabling more water in the ballast tank to be discharged. On the other hand, the first heating source can also maintain the air temperature at the elevated temperature and reduce the degree of volume contraction of the air when it is cooled by water, improving the drainage efficiency of the air and carbon dioxide linked drainage device.

[0014] The rupture diaphragm, as a pressure-sensitive component, 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 on the one hand, and can optimize the working pressure range of the drainage device with air-carbon dioxide linkage on the other hand, thereby improving the drainage efficiency. When the pressure reaches the first preset value, the rupture diaphragm automatically tears, enabling high-pressure air to smoothly enter the decompression chamber and promote the drainage process.

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 closely fit between the first plate portion and the first peripheral wall, effectively preventing the air located between the first plate portion and the first bottom wall from entering between the first plate portion and the second bottom wall, forming a thicker air cushion in the ballast tank, further reducing the probability of carbon dioxide being cooled by water, and improving the stability and reliability of the air and carbon dioxide linked drainage device.

The multiple power units in the first power unit group are arranged in sequence along the second direction, and the multiple power units in the second power unit group are arranged in sequence along the third direction.

[0032] The second direction is parallel to the third direction, and the first power unit group and the second power unit group are arranged at intervals.

[0047] With the maturity and development of underwater navigation technology, an underwater vehicle needs to drain water during the process of surfacing. For example, when unexpected situations such as stuck rudder, water ingress, or depth drop occur to the underwater vehicle, a part of the stored seawater needs to be quickly drained within a short time to provide positive buoyancy and achieve the safe surfacing of the underwater vehicle.

[0048] The biggest problem is that underwater vehicles generally use compressed air or high-temperature gas to drain water. The compressed air drainage device compresses and pressurizes the air in advance and stores it in a high-pressure air bottle. When needed, open the valve on the pipeline connecting 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 seals the solid agent in the gas generator. When needed, the agent is ignited by an electrical signal to cause a chemical reaction in the agent 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 back pressure of the water. As the working depth of the underwater vehicle gradually increases, the drainage capacity gradually decreases. The gas produced by the high-temperature gas drainage is easy to cause secondary combustion, which is not conducive to safety. If the water in the ballast tank is directly discharged using a push plate or other device, due to the high pressure underwater, the pressure on the push plate is large, which can easily cause fatigue damage and fracture of the push plate. Compressed air and the water in the ballast water tank form an air cushion, and then liquid carbon dioxide is converted into gas for drainage. The ultra-high pressure during the carbon dioxide conversion process discharges the water in the ballast water tank, thus avoiding direct contact and cooling of carbon dioxide and water.

[0049] However, in the related art, the temperature of the air decreases during the release process and when it comes into contact with water, causing the volume of the air to shrink, thereby reducing the drainage capacity of the drainage device that links air and carbon dioxide.

[0050] In view of this, an embodiment of the present application proposes a drainage device in which air and carbon dioxide are linked together. The drainage device in which air and carbon dioxide are linked together includes a power unit, an air unit, a pressure reducing unit and a guide assembly.

[0051] 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. A first heating source is arranged in the second storage chamber, and the first heating source is suitable for generating heat after receiving a signal to heat the air stored in the second storage chamber.

[0052] In the above solution, 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 linked drainage device operates, on the one hand, the first heating source can increase the temperature of the air in the second storage chamber, causing the air volume to expand, and thus enabling more water in the ballast tank to be discharged. On the other hand, the first heating source can also maintain the air temperature at the elevated temperature, reducing the probability of the air volume shrinking due to cooling when encountering water, and improving the drainage efficiency and drainage performance of the air and carbon dioxide linked drainage device.

[0053] The first storage chamber of the power unit disclosed in the embodiment of the present application can store liquid carbon dioxide. The liquid carbon dioxide can be excited by a heating element or an exciting 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 tank.

[0054] For the convenience of description, the following embodiments will be described by taking the air and carbon dioxide linked drainage device of an embodiment of the present application as an example.

[0056] Please refer to Figures 1 to 4, in 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 diversion 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 that can be selectively communicated with the first storage chamber 114 and the second storage chamber 121. The diversion assembly 140 has a first air inlet 141 and a first air outlet 142. The first air inlet 141 is communicated with the pressure reducing chamber 133, and the first air outlet 142 is communicated with the ballast tank 150. Wherein, a first heating source 160 is arranged in the second storage chamber 121, and 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.

[0057] The air and carbon dioxide linked drainage device 100 includes a power unit 113. Under the compression of the power unit 113, carbon dioxide is in a liquid state in the first storage chamber 114, and the carbon dioxide is stored in the first storage chamber 114. The air unit 120 includes a second storage chamber 121 for storing high-pressure air, and the air can be in a gaseous state in the second storage chamber 121. The pressure reducing unit 130 has a pressure reducing chamber 133. Exemplarily, the pressure reducing chamber 133 can be configured as a hollow thin-walled cylinder. The pressure reducing chamber 133 can be selectively communicated with the first storage chamber 114 and the second storage chamber 121. The carbon dioxide in the first storage chamber 114 can enter the pressure reducing chamber 133. When the carbon dioxide enters the pressure reducing chamber 133, the pressure of the carbon dioxide decreases, enabling the carbon dioxide to expand more fully, increasing the volume of the carbon dioxide, and thus enhancing the drainage capacity of the air and carbon dioxide linked drainage device 100. The high-pressure air stored in the second storage chamber 121 can also enter the pressure reducing chamber 133. After the air enters the pressure reducing chamber 133, the pressure will also decrease, and the air expands more fully, increasing the volume of the air, and thus enhancing the drainage capacity of the air and carbon dioxide linked drainage device 100. The diversion assembly 140 has a first air inlet 141 and a first air outlet 142. After air or carbon dioxide enters the pressure reducing chamber 133, it then enters the first air inlet 141 of the diversion assembly 140 from the pressure reducing chamber 133, then exits the diversion assembly 140 from the first air outlet 142, and then enters the ballast tank 150. Water is stored in the ballast tank 150. After air or carbon dioxide enters the ballast tank 150, the water in the ballast tank 150 will be discharged.

[0058] Since the temperature of supercritical carbon dioxide decreases when it meets water, its density increases and its volume shrinks. As a result, the water drainage ability of carbon dioxide will weaken. Therefore, the high-pressure air stored in the second storage chamber 121 can be discharged first, and then carbon dioxide can be discharged to avoid direct contact between carbon dioxide and water. Exemplarily, first, the high-pressure air in the second storage chamber 121 of the air unit 120 is discharged, making it enter the pressure reduction chamber 133, and then enter the diversion assembly 140 from the pressure reduction chamber 133. After flowing through the diversion assembly 140, it enters the ballast tank 150, which can discharge part of the water in the ballast tank 150. Then, an air cushion is formed in the ballast tank 150. Then, the carbon dioxide in the first storage chamber 114 is released, and the carbon dioxide in the first storage chamber 114 enters the ballast tank 150, whereby the water in the ballast tank 150 can be discharged. Carbon dioxide is in a liquid state at a certain pressure and temperature, with a large density and convenient storage. After the carbon dioxide is heated and pressurized, it can be quickly converted into a supercritical state, with its volume expanding several times and its instantaneous work capacity being strong. It can discharge water under the condition of relatively high water pressure.

[0059] When the air stored in the second storage chamber 121 is discharged into the ballast tank 150, the air directly contacts the water in the ballast tank 150. During the air release process and when it contacts the water, the temperature decreases and the volume will shrink, reducing the discharge of water in the ballast tank 150. Therefore, 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, on the one hand, the air expands due to heat and its volume increases. When the air is discharged into the ballast tank 150, the air with a larger volume can discharge more water in the ballast tank 150, thereby improving the efficiency and performance of the drainage device 100 with air-carbon dioxide linkage. In addition, after receiving the signal, the first heating source 160 generates heat, which can continuously heat the air and keep the air temperature roughly in a balanced range. In this way, the volume expansion of the air can be maintained, the probability of the air cooling and shrinking when it meets water can be reduced, and the use efficiency of the drainage device 100 with air-carbon dioxide linkage can be improved.

[0060] Moreover, the air and carbon dioxide linked drainage device 100 combines liquid carbon dioxide and high-pressure air as the power source. Liquid carbon dioxide can quickly enter the supercritical state when heated, providing a powerful driving force. For a large underwater vehicle 1000, once the position of the underwater vehicle 1000 is deep in the seabed, the water pressure on the ballast tank 150 is relatively large. Without the powerful driving force of carbon dioxide, it is difficult to drain the water in the ballast tank 150. And the high-pressure air can also be used as auxiliary power to ensure the continuity and stability of drainage. The harmless carbon dioxide gas will not pollute the environment when discharged into the atmosphere. At the same time, the design of this 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, this device has high reliability and durability, and can operate stably for a long time and meet various drainage requirements.

[0061] Specifically, a first heating source 160 is arranged 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 operates, on the one hand, the first heating source 160 can increase the temperature of the air in the second storage chamber 121, and the air volume expands, so that more water in the ballast tank 150 can be drained. On the other hand, the first heating source 160 can also maintain the air temperature at the increased temperature, reducing the probability of the air cooling and shrinking in volume when encountering water, and improving the drainage efficiency and drainage performance of the air and carbon dioxide linked drainage device 100.

[0062] Please refer to Figures 1 to 7 , exemplarily, the power unit 113 has a second outlet 115, and carbon dioxide can enter the decompression chamber 133 from the second outlet 115.

[0063] Please refer to Figures 1 to 8 , the decompression unit 130 has a first decompression inlet 134 and a first decompression outlet 135. The first decompression inlet 134 can communicate with the first storage chamber 114 and the second storage chamber 121. Air or carbon dioxide can enter the decompression chamber 133 from the first decompression inlet 134. The first decompression outlet 135 can communicate with the first air inlet 141 of the diversion assembly 140. The decompressed air or carbon dioxide can exit the decompression chamber 133 from the first decompression outlet 135 and enter the diversion assembly 140.

[0064] Please refer to Figures 1 to 5 , in this embodiment, the first heating source 160 is configured as an excitation agent assembly. The excitation agent assembly includes a medicine body and an excitation unit. The excitation unit is adapted to excite the medicine body after receiving a signal, so that the medicine body undergoes a chemical reaction and generates heat.

[0065] The excitation agent component can rapidly excite the agent body upon receiving a signal, causing it to undergo a chemical reaction and generate a large amount of heat. The ability to instantaneously heat enables the device to reach the required temperature within a short time, thereby quickly heating the high-pressure air and improving the drainage efficiency.

[0066] Compared with traditional heating elements, the excitation agent component usually has a simpler structure and fewer components, which helps reduce the manufacturing cost and maintenance cost. At the same time, since the agent body and the excitation unit are integrated, the complexity of installation and debugging is also reduced.

[0067] The excitation agent component only needs to provide a transient low-voltage electrical signal and usually has high reliability and stability. 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 emergencies, the device only needs to provide a low-voltage backup power supply and can still rely on the heat provided by the agent component to maintain the drainage operation.

[0068] Specifically, the excitation unit is adapted to excite the agent body upon receiving a signal, causing the agent body to undergo a chemical reaction and generate heat, which can improve the drainage efficiency of the air and carbon dioxide linked drainage device 100 and reduce the probability of failure of the air and carbon dioxide linked drainage device 100.

[0069] Please refer to Figures 1 to 5 , in this embodiment, the first heating source 160 is configured as a PTC heating component.

[0070] The PTC heating component uses a positive temperature coefficient thermistor (PTC) material as the core element and has the characteristic that the resistance value increases with the increase in temperature. This characteristic enables the PTC heating component to automatically limit the temperature during the heating process and automatically stabilize near the set temperature after reaching the set temperature, thereby achieving efficient heating and precise temperature control. This automatic temperature control function helps maintain the stable heating of the air in the air and carbon dioxide linked drainage device 100 and improves the drainage efficiency.

[0071] The PTC heating component does not generate open flames during the heating process and does not exhibit the common surface "reddening" phenomenon of electric heating tube heaters, thus greatly reducing safety hazards such as fires and scalds. In addition, the PTC heating component also has good insulation performance and electrical safety performance and can operate stably in various harsh environments, ensuring the safety and reliability of the air and carbon dioxide linked drainage device 100.

[0072] The power of the PTC heating component can be automatically adjusted according to the change in the air temperature of the second storage chamber 121, enabling the drainage device 100 with air-carbon dioxide linkage to adapt to the working environment under different temperature conditions. In addition, the PTC heating component also has a wide voltage adaptability and can maintain a stable heating effect within different voltage fluctuation ranges.

[0073] Specifically, the first heating source 160 is configured as a PTC heating component, capable of efficient heating and precise temperature control. This automatic temperature control function helps to maintain stable heating of the air within the drainage device 100 with air-carbon dioxide linkage, improving the drainage efficiency.

[0074] Please refer to Figure 5 , in this embodiment, the drainage device 100 with air-carbon dioxide linkage further includes a thermal insulation layer 170. The thermal insulation layer 170 is coated on the inner sidewall of the second storage chamber 121 to insulate the air within the second storage chamber 121.

[0075] The drainage device 100 with air-carbon dioxide linkage further includes a thermal insulation layer 170. The thermal insulation layer 170 is coated on the inner sidewall of the second storage chamber 121. That is to say, the thermal insulation layer 170 will not impede or affect the air flow within the second storage chamber 121. After the first heating source 160 heats the air within the second storage chamber 121, since the drainage device 100 with air-carbon dioxide linkage is usually located outside the underwater vehicle 1000, the outer wall of the second storage chamber 121 is in direct contact with seawater, which easily cools the air within the second storage chamber 121, thereby causing volume contraction.

[0076] By providing the thermal insulation layer 170 within the second storage chamber 121 and arranging the thermal insulation layer 170 on the inner sidewall of the second storage chamber 121, the air within the second storage chamber 121 can be insulated, reducing the probability of air cooling and improving the operating efficiency and performance of the drainage device 100 with air-carbon dioxide linkage.

[0077] Please refer to Figure 5 , in this embodiment, the air unit 120 has a first outlet 122. The first outlet 122 connects the second storage chamber 121 and the decompression chamber 133. The air unit 120 further includes a rupture diaphragm 123. The rupture diaphragm 123 is disposed at the first outlet 122 and is configured to tear when the pressure within the second storage chamber 121 reaches a first preset value.

[0078] The air unit 120 has a first outlet 122. The first outlet 122 connects the second storage chamber 121 and the decompression 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 decompression chamber 133. The decompression chamber 133 is in communication with the second storage chamber 121 through the first outlet 122.

[0079] The air unit 120 further includes a bursting diaphragm 123. The bursting diaphragm 123 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 to say, after the air pressure reaches the first preset value, the air stored in the second storage chamber 121 can break through the bursting diaphragm 123, and then the air enters the decompression chamber 133 from the second storage chamber 121.

[0080] Specifically, the bursting 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 on the one hand, and can optimize the working pressure range of the drainage device 100 for air and carbon dioxide linkage on the other hand, thereby improving the drainage efficiency. When the pressure reaches the first preset value, the bursting diaphragm 123 automatically tears, enabling the high-pressure air to smoothly enter the decompression chamber 133 and promote the drainage process.

[0081] 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, 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 the first outlet 122. The air unit 120 further 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.

[0082] 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 oppositely arranged. 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 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 during the process of the air unit 120 releasing air, the air inside the air unit 120 cannot all be discharged into the ballast tank 150 for drainage, a first plate portion 127 can be arranged inside the air unit 120. The outer peripheral surface of the first plate portion 127 is slidably connected to the inner peripheral surface of the first peripheral wall 124. That is to say, along the first direction X, the first plate portion 127 and the first peripheral wall 124 can have relative displacement, the volume of the second storage chamber 121 decreases, and the first plate portion 127 can push the remaining air in the air bottle towards the ballast tank 150, improving the utilization efficiency of the air inside the air unit 120.

[0083] Specifically, the air unit 120 further 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 the air in the air bottle, enable the ballast tank 150 to drain more water, form a thicker air cushion, further reduce the probability of cooling when carbon dioxide contacts water, and improve the operating efficiency and reliability of the air-carbon dioxide linkage drainage device 100.

[0084] Please refer to Figure 5 , in this embodiment, the air unit 120 further includes a first driving member 180. The first driving member 180 is arranged 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.

[0085] The air unit 120 includes a first driving member 180. The first driving member 180 can be configured as a driving motor. The first driving member 180 is arranged on the second bottom wall 126. The first driving member 180 has a power output end, and the power output end of the first driving member 180 is connected to the first plate portion 127. The first driving member 180 can control the movement of the first plate portion 127 in the first direction X.

[0086] Specifically, the power output end of the first driving member 180 is connected to the first plate portion 127. The introduction of the first driving member 180 provides an additional power source for the air unit 120. By precisely controlling the operating speed and strength of the first driving member 180, and then controlling the movement of the first plate portion 127, fine adjustment of parameters such as the internal air flow and pressure of the air unit 120 can be achieved, thereby improving the operating efficiency of the air-carbon dioxide linkage drainage device 100.

[0087] Please refer to Figure 5 , in this embodiment, the air unit 120 further includes a first seal 190, and the first seal 190 is disposed between the inner peripheral surface of the first plate portion 127 and the first peripheral wall 124.

[0088] The first seal 190 is disposed between the inner peripheral 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 between the first plate portion 127 and the second bottom wall 126. In this way, the pressure of the air in the air unit 120 can be increased, and the air in the air unit 120 can be pressed into the ballast tank 150, thereby forming a thicker air cushion, discharging more water from the ballast tank 150, further reducing the volume shrinkage caused by the cooling of carbon dioxide, and improving the drainage capacity of the drainage device 100 with air-carbon dioxide linkage. It can be understood that the material of the first seal 190 can be nitrile rubber (NBR), silicone rubber, and fluororubber. Nitrile rubber (NBR) has good oil resistance and is suitable for sealing occasions in contact with oil media. Silicone rubber has good high-temperature and low-temperature stability and can maintain the sealing performance under extreme temperature conditions. Fluororubber has excellent corrosion resistance, high temperature resistance, and oil resistance, and is suitable for sealing of strong corrosive, high-temperature, or oil media.

[0089] Specifically, the first seal 190 is disposed between the inner peripheral surface of the first plate portion 127 and the first peripheral wall 124, which can enable the air to form a thicker air cushion in the ballast tank 150, further reducing the probability of carbon dioxide cooling when encountering water and improving the drainage efficiency of the drainage device 100 with air-carbon dioxide linkage.

[0090] Please refer to Figure 6 , in this embodiment, the first plate portion 127 further includes a first groove 128. The first groove 128 is disposed on the outer peripheral surface of the first plate portion 127. The first groove 128 is configured to be annular and extends along the circumferential direction of the first plate portion 127. The first seal 190 is disposed in the first groove 128.

[0091] The first plate portion 127 further includes a first groove 128. The opening of the first groove 128 faces the first peripheral wall 124. The first groove 128 is provided on the outer peripheral surface of the first plate portion 127. The shape of the first groove 128 is configured to be annular and extends along the circumferential direction of the first plate portion 127. It can be understood that the opening direction of the first groove 128 is substantially 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 installation position for the first seal 190, ensuring that the first seal 190 can closely fit between the first plate portion 127 and the first peripheral wall 124, effectively preventing the 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. In addition, the design of the first groove 128 makes the installation of the first seal 190 more convenient and fast, without additional fixing devices or adhesives, reducing the installation difficulty and cost. The existence of the first groove 128 can enhance the structural strength of the first plate portion 127 to a certain extent, enabling it to better withstand external pressure or impact, and improving the overall stability of the air and carbon dioxide linkage drainage device 100.

[0092] Specifically, the first groove 128 is configured to be annular and extends along the circumferential direction of the first plate portion 127. The first seal 190 is disposed in the first groove 128, which can provide a stable installation position for the first seal 190, ensuring that the first seal 190 can closely fit between the first plate portion 127 and the first peripheral wall 124, effectively preventing the 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, forming a thicker air cushion in the ballast tank 150, further reducing the probability of carbon dioxide cooling when encountering water, and improving the stability and reliability of the air and carbon dioxide linkage drainage device 100.

[0093] 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 respectively connected to the pressure detection unit and the first driving member 180. The pressure detection unit is disposed at the first outlet 122.

[0094] 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 180 respectively. The pressure detection unit sends the detected air pressure value to the control unit. The control unit controls the first driving member 180 according to the data detected by the pressure detection unit, and controls 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 lower than the first threshold value, the control unit controls the first driving member 180 to move the first plate portion 127. When the air pressure value is higher than the first threshold value, the control unit does not control the first driving member 180. 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.

[0095] Specifically, the control unit is respectively connected to the pressure detection unit and the first driving member 180. 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 127 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 150 is discharged, and a thicker air cushion is formed in the ballast water tank 150, 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.

[0096] Please refer to Figures 1 to 7 In this embodiment, the air and carbon dioxide linked drainage device 100 includes a plurality of power unit groups 110 and a plurality of decompression units 130, the plurality of power unit groups 110 correspond one to one with the plurality of decompression units 130, each power unit group 110 includes a plurality of power units 113, and 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.

[0097] The air and carbon dioxide linked drainage device 100 includes multiple power unit groups 110, enabling the air and carbon dioxide linked drainage device 100 to flexibly adjust power output according to drainage requirements. When a large amount of drainage is required for the ballast tank 150, more power unit groups 110 can be activated to improve the drainage efficiency. The multiple power unit groups 110 and the multiple pressure reduction units 130 correspond one by one. That is to say, the carbon dioxide of the multiple power unit groups 110 can exit the power unit groups 110 and then enter the pressure reduction 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 communicated with the pressure reduction chamber 133, and then the carbon dioxide exits the first storage chamber 114 and enters the pressure reduction chamber 133. For example, a bursting diaphragm 123 can be arranged between the pressure reduction chamber 133 and the first storage chamber 114. When the pressure value of the carbon dioxide exceeds a certain threshold, the carbon dioxide will break through the bursting diaphragm 123 and enter the interior of the pressure reduction chamber 133 from the first storage chamber 114.

[0098] Specifically, the first storage chamber 114 of each power unit group 110 can be selectively communicated with the pressure reduction chamber 133 of the corresponding pressure reduction unit 130. When the underwater vehicle 1000 needs to float, carbon dioxide can be made to enter the ballast tank 150, and then the water is discharged to improve the drainage efficiency of the air and carbon dioxide linked drainage device 100.

[0099] 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, and the second heating source 200 is arranged in the pressure reduction chamber 133.

[0100] The second heating source 200 is arranged in the pressure reduction chamber 133, which can heat the air or carbon dioxide in the pressure reduction chamber 133, reduce the degree of temperature drop of the air or carbon dioxide when encountering water, and improve the operating efficiency of the air and carbon dioxide linked drainage device 100.

[0101] Please refer to Figures 1 to 8 In this embodiment, the second heating source 200 is configured as a heating sheet, and the heating sheet is attached to the inner wall of the pressure reduction chamber 133.

[0102] The heating sheet is attached to the inner wall of the pressure reduction chamber 133, which can reduce the space occupancy rate of the second heating source 200 in the pressure reduction chamber 133 and reduce the influence of the second heating source 200 on the flow of air or carbon dioxide.

[0103] Please refer to Figures 1 to 8, in this embodiment, the multiple power unit groups 110 include a first power unit group 111 and a second power unit group 112. The multiple power units 113 in the first power unit group 111 are arranged in sequence along a second direction, and the multiple power units 113 in the second power unit group 112 are arranged in sequence along a third direction. The second direction is parallel to the third direction.

[0104] 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 in the first power unit group 111 are arranged in sequence along a second direction, while the multiple power units 113 in the second power unit group 112 are arranged in sequence along a third direction. The second direction is parallel to the third direction. It can be understood that the first power unit group 111 and the second power unit group 112 are arranged at intervals. In this way, if it is necessary to attach the multiple power unit groups 110 to a certain component of the underwater vehicle 1000, the space occupancy rate of the underwater vehicle 1000 can be improved.

[0105] Please refer to Figures 1 to 8 , in this embodiment, the multiple 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 can be selectively communicated with the pressure reducing chamber 133 of the first pressure reducing unit, and the pressure reducing chamber 133 of the second pressure reducing unit can be selectively communicated with 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 the second direction, and the second pressure reducing pipeline 132 extends along the third direction.

[0106] The multiple pressure reducing units 130 include a first pressure reducing unit and a second pressure reducing unit. The first pressure reducing unit and the second pressure reducing unit can be arranged at intervals. The first storage chamber 114 of the first power unit group 111 can be communicated with the pressure reducing chamber 133 of the first pressure reducing unit. Liquid carbon dioxide can be heated in the first storage chamber 114, and the liquid carbon dioxide becomes supercritical carbon dioxide, and then enters the pressure reducing chamber 133 of the first pressure reducing unit from the first storage chamber 114. Similarly, the pressure reducing chamber 133 of the second pressure reducing unit can be selectively communicated with the first storage chamber 114 of the second power unit group 112, and the carbon dioxide in the second storage chamber 121 can enter the pressure reducing chamber 133 from the second storage chamber 121.

[0107] The first pressure reducing unit is configured as the first pressure reducing pipeline 131, and multiple pressure reducing units 130 of the first pressure reducing unit are all communicated with the first pressure reducing pipeline 131. The second pressure reducing unit is configured as the second pressure reducing pipeline 132, and multiple pressure reducing units 130 of the second pressure reducing unit are all communicated with the second pressure reducing pipeline 132. The first pressure reducing pipeline 131 extends along the second direction, the second pressure reducing pipeline 132 extends along the third direction, and the first pressure reducing pipeline 131 and the second pressure reducing pipeline 132 are arranged at intervals.

[0108] Specifically, the first pressure reducing pipeline 131 extends along the second direction, and the second pressure reducing pipeline 132 extends along the third direction, so that the first pressure reducing pipeline 131 and the second pressure reducing pipeline 132 can be more closely arranged on the underwater vehicle 1000, making the structure of the underwater vehicle 1000 more compact and improving the space utilization rate of the underwater vehicle 1000.

[0109] Please refer to Figures 1 to 8 , in this embodiment, the number of power units 113 of the first power unit group 111 is less than the number of power units 113 of 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.

[0110] Since the number of power units 113 of the first power unit group 111 is less than the number of power units 113 of the second power unit group 112, the pressure of the carbon dioxide ejected by the first power unit group 111 will be weaker than the pressure of the carbon dioxide ejected by the second power unit group 112. Therefore, the inner diameter design of the first pressure reducing pipeline 131 can be smaller than the inner diameter of the second pressure reducing pipeline 132, which can ensure 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 the carbon dioxide ejected from the flow guiding component 140 is relatively balanced, improving the drainage stability and reliability of the air and carbon dioxide linkage drainage device 100.

[0111] In addition, the carbon dioxide ejected by the first power unit group 111 will flow through the pressure reducing chamber 133 of the first pressure reducing pipeline 131 and the pressure reducing chamber 133 of the second pressure reducing pipeline 132, and then enter the inside of the ballast tank 150 from the flow guiding component 140, while the carbon dioxide ejected by the second power unit group 112 can directly enter the flow guiding component 140 from the pressure reducing chamber 133 of the second pressure reducing pipeline 132, and then enter the ballast tank 150. Therefore, the inner diameter of the first pressure reducing pipeline 131 of the first power unit 113 can be smaller than the inner diameter of the second pressure reducing pipeline 132, reducing the manufacturing cost of the air and carbon dioxide linkage drainage device 100.

[0112] Specifically, the inner diameter of the first pressure relief pipeline 131 is smaller than that of the second pressure relief pipeline 132, which can improve the drainage stability and reliability of the air and carbon dioxide linkage drainage device 100 on the one hand, and reduce the manufacturing cost of the air and carbon dioxide linkage drainage device 100 on the other hand.

[0113] Please refer to Figures 1 to 8 , in this embodiment, the pressure relief chambers 133 of the multiple pressure relief units 130 communicate with each other, and the first air inlet 141 of the flow guiding assembly 140 communicates with at least one of the multiple pressure relief chambers 133.

[0114] Since the pressure relief chambers 133 of the multiple pressure relief units 130 communicate with each other, they can jointly share and balance the pressure. This helps to achieve a more uniform and stable pressure distribution throughout the system, reducing pressure fluctuations and instability.

[0115] When the first air inlet 141 of the flow guiding assembly 140 communicates with at least one of the multiple pressure relief chambers 133, after air and carbon dioxide enter the pressure relief chamber 133, they can enter the flow guiding assembly 140 from the first air inlet 141 of the flow guiding assembly 140, and then enter the ballast tank 150. In this way, even if the air and carbon dioxide linkage drainage device 100 needs to increase the drainage volume or drainage capacity, the power unit 113 can be increased, and then the increased power unit 113 can be communicated with the pressure relief chamber 133, without the need for multiple flow guiding assemblies 140, greatly reducing the manufacturing cost of the air and carbon dioxide linkage drainage device 100. In addition, through parallel pressure relief by multiple pressure relief units 130, this parallel pressure relief method can significantly improve the pressure relief efficiency, enabling the gas to reach the required pressure level faster, and the manufacturing cost of a single unit is also low.

[0116] Specifically, the pressure relief chambers 133 of the multiple pressure relief units 130 communicate with each other, and the first air inlet 141 of the flow guiding assembly 140 communicates with at least one of the multiple pressure relief chambers 133. On the one hand, parallel pressure relief can improve the pressure relief efficiency, and on the other hand, it can also reduce the manufacturing cost of the underwater vehicle 1000.

[0117] Please refer to Figures 1 to 9 , this embodiment of the present application also provides an underwater vehicle 1000, including the air and carbon dioxide linkage drainage device 100 according to any one of the embodiments of the present application.

[0118] In some embodiments, air or carbon dioxide can enter the ballast tank 150 from the air and carbon dioxide linkage drainage device 100, and then discharge the water in the ballast tank 150 from the first pipeline 210 out of the underwater vehicle 1000, thereby reducing the weight of the underwater vehicle 1000.

[0119] Please refer to Figures 9 to 11, in some embodiments, when the underwater vehicle 1000 needs to quickly surface and the air and carbon dioxide linked drainage device 100 needs to quickly drain water, upon receiving the quick surfacing signal of the underwater vehicle 1000, the control unit can, according to the surfacing requirement of the underwater vehicle 1000, control the first driving member 180 to accelerate the driving of the position of the first plate portion 127, so that more air enters the ballast tank 150 in a shorter time, enabling the underwater vehicle 1000 to discharge more water, thereby enabling the underwater vehicle 1000 to quickly surface.

[0120] Please refer to Figures 9 to 11 , in some embodiments, a flow guiding assembly 140 is provided between the air and carbon dioxide linked drainage device 100 and the ballast tank 150. One end of the flow guiding assembly 140 is connected to the air and carbon dioxide linked drainage device 100, and the other end of the flow guiding assembly 140 is connected to the ballast tank 150. Air or carbon dioxide can enter the ballast tank 150 from the air and carbon dioxide linked drainage device 100 through the flow guiding assembly 140. A first exhaust valve 260 can be provided on the flow guiding assembly 140. The first exhaust valve 260 is used to control the exhaust volume and exhaust speed of the air and carbon dioxide linked drainage device 100 per unit time, that is, the flow rate and flow velocity of the gas. Exemplarily, when the underwater vehicle 1000 is navigating underwater and needs to precisely control the surfacing speed, the first 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 flow guiding assembly 140, thereby controlling the flow rate and flow velocity of the gas passing through the flow guiding assembly 140. Exemplarily, when the underwater vehicle 1000 needs to quickly surface, for example, when the surfacing speed is 10 m / s, the first exhaust valve 260 can be fully opened, enabling the gas (carbon dioxide or air) to pass through the flow guiding assembly 140 at the maximum flow rate and flow velocity and enter the ballast tank 150, causing the water in the ballast tank 150 to be discharged. When the underwater vehicle 1000 needs to surface at a moderate speed, for example, when the surfacing speed is 5 m / s, the first exhaust valve 260 can be in a semi-open state, enabling the gas to flow out at a corresponding flow rate and flow velocity per unit time, thereby precisely controlling the surfacing of the underwater vehicle 1000.

[0121] Please refer to Figures 9 to 11, in some embodiments, the underwater vehicle 1000 further includes a gas recovery device 270. The gas recovery device 270 is selectively connected to the air and carbon dioxide linked drainage device 100. When the underwater vehicle 1000 floats, 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, and the air and carbon dioxide in the ballast tank 150 flow into the gas recovery device 270. The ballast tank 150 is refilled with water, thereby increasing the weight of the underwater vehicle 1000, making the weight of the underwater vehicle 1000 greater than the buoyancy, and thus enabling the underwater vehicle 1000 to sink.

[0122] 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 respectively connected to the outer peripheral edge of the third bottom wall 272 and the outer peripheral edge of the fourth bottom wall 273. The third bottom wall 272 is provided with a third outlet 274, and the third outlet 274 is connected to the ballast tank 150. The air or carbon dioxide in the ballast tank 150 enters the gas recovery device 270 through the third outlet 274. The gas recovery device 270 further includes a second plate portion 275. The outer peripheral surface of the second plate portion 275 is slidably connected to the inner peripheral surface of the second peripheral wall 271. The second plate portion 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 portion 275 is controlled to move away from the third outlet 274. When the underwater vehicle 1000 needs to float, the second plate portion 275 is controlled to move closer to the third outlet 274, and the carbon dioxide and air in the gas recovery device 270 are discharged into the ballast tank 150.

[0123] Please refer to Figures 9 to 11, in some embodiments, the ballast water tank 150 discharges water through the outlet of the first pipe 210. Along the circumference of the outlet of the first pipe 210, Helmholtz resonators are provided. Each Helmholtz resonator unit is processed from a 316L stainless steel matrix and contains a cylindrical cavity and a slit neck inside. Exemplarily, 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 resonance frequency of the Helmholtz resonator, high-speed oscillations are generated in the neck, and the sound energy is converted into heat energy through the viscous dissipation and heat conduction effects. A piezoelectric ceramic sheet can be embedded in the neck of the Helmholtz resonator. An MEMS hydrophone array can be provided at the outlet of the first pipe 210. The MEMS hydrophone is used to collect noise signals in real time, and an analog voltage is output to the corresponding piezoelectric ceramic sheet through a conversion module. The adjustment time can be less than 5 seconds. The Helmholtz resonator operates to reduce or eliminate the drainage noise at the outlet of the first pipe 210.

[0124] Please refer to Figures 9 to 11 , in some embodiments, the underwater vehicle 1000 can be a submarine.

[0125] 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 further includes a second driving member 283. The second driving member 283 is disposed on the fifth bottom wall 281, and the power output end of the second driving member 283 is connected to the third plate portion 284. The power unit 113 further includes a second sealing member 285. The second sealing member 285 is disposed between the third plate portion 284 and the inner peripheral surface of the third peripheral wall 280. The third plate portion 284 further includes a second groove 286. The second groove 286 is disposed on the outer peripheral surface of the third plate portion 284. The second groove 286 is configured to be annular and extends along the circumference of the third plate portion 284. The second sealing member 285 is disposed in the second groove 286. A second opening 115 is provided on the sixth bottom wall 282. The second opening 115 communicates with the decompression chamber 133. The second driving 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 decompression chamber 133, thereby enabling more water to be discharged, improving the utilization rate of carbon dioxide, and improving the drainage efficiency of the air-carbon dioxide linkage drainage device 100.

[0126] In some embodiments, the air and carbon dioxide linked drainage device 100 further includes a bionic gill type multi-layer gas exchange membrane. The multi-layer gas exchange membrane includes a base layer, a functional layer, and a protective layer. The base layer is configured as polytetrafluoroethylene (PTFE) and a porous membrane (pore size 0.2 microns) to provide mechanical support. The functional layer is configured as a lipid bilayer structure imitating fish gill cells and is embedded with a recombinant aquaporin-Z to selectively block the permeation of carbon dioxide molecules. The protective layer is configured as a silica nano-coating (thickness 50 nm) to prevent the attachment of biological fouling. The multi-layer gas exchange membrane is movably disposed inside the ballast tank 150 and located between the water and the air cushion, further reducing the probability of contact between carbon dioxide and water and the probability of carbon dioxide cooling and shrinking, enabling more water to be discharged from the air and carbon dioxide linked drainage device 100, and further improving the drainage efficiency of the air and carbon dioxide linked drainage device 100.

[0127] 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. The first buffer plate 290 can be disposed on the inner wall of the second decompression pipeline 132. A plurality of first holes 300 are provided on the first buffer plate 290. Along the thickness direction of the first buffer plate 290, the plurality of first holes 300 penetrate through the first buffer plate 290. The first hole 300 includes a first end 301 and a second end 302. Along the thickness direction of the first buffer plate 290, the first end 301 and the second end 302 are oppositely disposed. The radial dimension of the first end 301 is greater than that of the second end 302. From the first end 301 to the second end 302, the size of the first hole 300 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 flow guiding assembly 140. When air or carbon dioxide is released instantaneously, the pressure is relatively high, the impact force is relatively large, and the volume is relatively small. By providing the first buffer plate 290, air or carbon dioxide can be buffered, reducing the impact of air or carbon dioxide entering the ballast tank 150, enabling air and carbon dioxide to be more fully released in the second decompression pipeline 132, expanding the volume of air or carbon dioxide, and enabling more air or carbon dioxide to enter the ballast tank 150, thereby improving the drainage capacity of the air and carbon dioxide linked drainage device 100.
