Description

Technical Field

[0001] The present invention belongs to the technical field of floating devices, and particularly relates to an airship based on seawater ballast compensation. Background Art

[0002] An airship is an aircraft lighter than air. The biggest difference between it and a hot air balloon is that it has devices for propulsion and controlling the flight state. An airship consists of a huge streamlined hull, a gondola located below the hull, a tail surface for stability control, and a propulsion device. After a cargo airship jettisons its cargo, the weight suddenly decreases, resulting in excessive buoyancy. If the ballast is not compensated in time, it may cause the airship to lose control or structural damage. Traditional ballast systems mostly use sandbags or fresh water, but there are problems such as high cost and poor environmental protection. Summary of the Invention

[0003] The purpose of the present invention is to at least solve the problem of the relatively high cost of the existing airship ballast system. This purpose is achieved through the following technical solutions:

[0004] A first aspect of the present invention provides an airship based on seawater ballast compensation, comprising:

[0005] A hull having an accommodation space therein;

[0006] An airbag disposed in the accommodation space;

[0007] A ballast assembly including a water tank, a water conduit, and a driving pump. The water tank is connected to the bottom end of the hull. The water tank is provided with an opening. The driving pump is disposed in the water tank. One end of the driving pump is communicated with the water tank. The other end of the driving pump is connected to one end of the water conduit. The other end of the water conduit passes through the opening and is used for sucking seawater.

[0008] By using the airship based on seawater ballast compensation in this technical solution, the accommodation space of the hull is used to accommodate the airbag and also to support and fix the ballast assembly. The driving pump is disposed in the water tank and is used to suck seawater outside the water tank and guide it into the water tank, thereby increasing the weight of the airship. At the same time, the driving pump can also discharge the seawater in the water tank to the outside of the water tank through the water conduit to reduce the weight of the airship. The airship in the present invention can, after jettisoning or loading goods, compensate for the weight of the airship by extracting or discharging seawater through the ballast assembly, realizing the environmental protection utilization of seawater and reducing the ballast cost.

[0009] In addition, the airship based on seawater ballast compensation according to the present invention may further have the following additional technical features:

[0032] An airship is an aircraft lighter than air. The biggest difference between it and a hot air balloon is that it has devices for propulsion and flight state control. An airship consists of a huge streamlined hull, a gondola located below the hull, a tail surface for stability control, and a propulsion device. After a cargo airship jettisons its cargo, the sudden weight reduction leads to excessive buoyancy. If ballast is not compensated in time, it may cause the airship to lose control or structural damage. Traditional ballast systems mostly use sandbags or fresh water, but they have problems such as high cost, poor environmental protection, and complex operation. In the ocean transportation scenario, seawater resources are abundant and easily accessible, but difficulties such as seawater corrosion, rapid compensation efficiency, and system reliability need to be solved.

[0033] Figure 1 Schematically shows a schematic diagram of the overall structure of an airship based on seawater ballast compensation according to an embodiment of the present invention. Figure 2 For Figure 1 The structural schematic diagram of the middle water tank 31. As Figure 1 And 2 Shown, the present invention proposes an airship based on seawater ballast compensation. The airship based on seawater ballast compensation in the present invention includes a hull 10, an airbag 20, and a ballast assembly 30. The hull 10 has an accommodation space 11 inside. The airbag 20 is arranged in the accommodation space 11. The ballast assembly 30 includes a water tank 31, a water conduit, and a driving pump 33. The water tank 31 is connected to the bottom end of the hull 10. The water tank 31 is provided with an opening. The driving pump 33 is arranged inside the water tank 31. One end of the driving pump 33 is communicated with the water tank 31. The other end of the driving pump 33 is connected to one end of the water conduit. The other end of the water conduit passes through the opening and is used to suck seawater. In this embodiment, a flowmeter is integrated on the driving pump 33 to facilitate measuring the fluid flow rate of the driving pump 33. And the driving pump 33 in this embodiment supports bidirectional flow, that is, it can not only inject water but also drain water.

[0034] By using the airship based on seawater ballast compensation in the present technical solution, the accommodation space 11 of the hull 10 is used to accommodate the airbag 20 and also to support and fix the ballast assembly 30. The driving pump 33 is arranged inside the water tank 31 and is used to suck the seawater outside the water tank 31 and guide it into the water tank 31, thereby realizing the weight gain of the airship. At the same time, the driving pump 33 can also discharge the seawater in the water tank 31 through the water conduit to the outside of the water tank 31 to realize the weight loss of the airship. The airship in the present invention can, after jettisoning or loading cargo, compensate the weight of the airship by extracting or discharging seawater through the ballast assembly 30, realizing the environmental protection utilization of seawater and reducing the ballast cost.

[0035] Specifically, in this embodiment, the driving pump 33 is a two-way driving water pump, which is a water pump device capable of realizing the functions of pumping water or boosting pressure in two directions. Such a water pump usually has a two-way rotating impeller or a special mechanical structure to adapt to the requirements of different water flow directions. Using electric energy as the power source, the electric energy is converted into mechanical energy by the motor, and then the impeller inside the water pump is driven to rotate, so as to realize the suction of seawater at the end of the water conduit away from the driving pump 33, and to realize the discharge of seawater in the water tank 31, thereby meeting the weight gain and weight loss of the water tank 31, and finally realizing the weight gain and weight loss of the entire airship.

[0036] Specifically, in this embodiment, the water conduit is provided with a perforation, which enables the seawater in the water tank 31 and the sea to be connected. Among them, a sealing ring is arranged at the perforation. The sealing ring has good sealing performance within the working pressure and a certain temperature range, and as the pressure increases, it can automatically improve the sealing performance to ensure that the seawater in the water tank 31 will not leak. The sealing ring is arranged at the perforation and sleeved outside the water conduit, which has good sealing performance and improves the reliability of the water tank 31.

[0037] Specifically, in this embodiment, the other end of the water conduit passes through the perforation and is located below the water tank 31, which is convenient for the port at the other end of the water conduit to enter the seawater, thereby realizing the suction of seawater.

[0038] In some embodiments of the present invention, as Figure 2 shown, the water tank 31 includes a ballast chamber 311 and a drainage chamber 312. The ballast chamber 311 and the drainage chamber 312 are separated by a first partition plate 314. A first control valve 3141 is arranged on the first partition plate 314. The ballast chamber 311 and the drainage chamber 312 are connected through the first control valve 3141. The driving pump 33 is arranged in the ballast chamber 311. The perforation is connected to the ballast chamber 311. The water tank 31 is provided with a drainage hole connected to the drainage chamber 312, and a second control valve is arranged at the drainage hole. In this embodiment, the water tank 31 is separated into a ballast chamber 311 and a drainage chamber 312 by the first partition plate 314, and the first control valve 3141 of the first partition plate 314 can conduct or cut off the ballast chamber 311 and the drainage chamber 312.

[0039] Specifically, in this embodiment, as Figure 2As shown, the driving pump 33 is arranged in the ballast chamber 311. The driving pump 33 can suck seawater through the water conduit and guide the seawater to the ballast chamber 311. Then, the first control valve 3141 can open the connection between the ballast chamber 311 and the drainage chamber 312, thereby increasing the weight of the seawater carried by the water tank 31, and the drainage chamber 312 can increase the ballast weight of the overall water tank 31. On the other hand, when the airship needs to reduce weight, the driving pump 33 in the ballast chamber 311 can drain water out of the water tank 31 through the water conduit. At the same time, due to the arrangement of the drainage holes, the drainage chamber 312 can drain the seawater in the drainage chamber 312 by gravity, accelerating the drainage speed, and thus improving the ballast efficiency.

[0040] Specifically, in this embodiment, the drainage holes are located at the bottom end of the drainage chamber 312, facilitating the gravity drainage of the seawater in the drainage chamber 312 and improving the reliability. The second control valve can automatically conduct and cut off operations according to the electrical signal information, thereby draining or storing the seawater in the drainage chamber 312.

[0041] In some embodiments of the present invention, as Figure 2 shown, the ballast assembly 30 further includes an air pump 34. The air pump 34 is connected to the water tank 31, and the air pump 34 is connected to the drainage chamber 312 through an air inlet pipe 341. In this embodiment, when the airship needs to perform a weight reduction operation after loading goods, the second control valve is in an open state, the first control valve 3141 is in a cut-off state, and at the same time, the air pump 34 receives the corresponding electrical signal to start and inflates the drainage chamber 312 with high pressure through the air inlet hole. At this time, the drainage chamber 312 is in a sealed state. Due to the extrusion of the high-pressure gas, the seawater in the drainage chamber 312 can quickly pass through the drainage holes, thereby accelerating the drainage speed and improving the ballast efficiency.

[0042] Specifically, in this embodiment, an air inlet hole is provided on the water tank 31. One end of the air inlet pipe 341 is connected to the air pump 34, and the other end of the inlet end passes through the air inlet hole and is connected to the drainage chamber 312. A sealing ring is provided at the air inlet. The sealing ring has good sealing performance within the working pressure and a certain temperature range, and as the pressure increases, it can automatically improve the sealing performance to ensure that the gas introduced into the drainage chamber 312 by the air pump 34 does not leak. The sealing ring is arranged at the air inlet hole and sleeved outside the air inlet pipe 341, having good sealing performance and improving the reliability of the drainage chamber 312.

[0043] Specifically, in this embodiment, the air inlet hole is located at the top end of the drainage chamber 312 to ensure that it will not be immersed in the seawater in the drainage chamber 312, thereby affecting the extrusion efficiency of the high-pressure gas of the air pump 34 on the seawater.

[0044] Further, in the present embodiment, liquid level sensors are provided in both the drainage chamber 312 and the ballast chamber 311, which can detect the liquid level of seawater in the drainage chamber 312 and the ballast chamber 311 in real time, thereby knowing the real-time liquid level of seawater. When the seawater is at the extreme position, corresponding seawater increase and decrease processing can be carried out in the drainage chamber 312 and the ballast chamber 311 in a timely manner, improving the reliability.

[0045] In some embodiments of the present invention, as Figure 2 shown, the water tank 31 further includes an electrolysis chamber 313. A second partition plate 315 is provided between the electrolysis chamber 313 and the ballast chamber 311. A third control valve 3151 is provided on the second partition plate 315. The electrolysis chamber 313 and the ballast chamber 311 are connected through the third control valve 3151. The ballast assembly 30 further includes an adjustment airbag 36 and an electrolysis element 35. The adjustment airbag 36 is arranged in the accommodation space 11, and the electrolysis element 35 is arranged in the electrolysis chamber 313. The electrolysis chamber 313 is connected to the adjustment airbag 36 through an air duct 351. In the present embodiment, a first partition plate 314 and a second partition plate 315 are respectively provided in the water tank 31. The first partition plate 314 is used to separate the ballast chamber 311 and the drainage chamber 312, and the ballast chamber 311 and the drainage chamber 312 can be connected through the first control valve 3141 on the first partition plate 314. The second partition plate 315 is used to separate the ballast chamber 311 and the electrolysis chamber 313, and the ballast chamber 311 and the electrolysis chamber 313 can be connected through the second control valve on the second partition plate 315.

[0046] Specifically, in the present embodiment, as Figure 2 shown, a third partition plate 316 is further provided in the water tank 31. The third partition plate 316 separates the electrolysis chamber 313 and the drainage chamber 312. One side of the first partition plate 314 is connected to one side of the second partition plate 315. The other side of the first partition plate 314 and the other side of the second partition plate 315 are respectively connected to the inner wall surface of the water tank 31. One side of the third partition plate 316 is connected to the connection part of the first partition plate 314 and the second partition plate 315, and the other side of the third partition plate 316 is connected to the inner wall surface of the water tank 31. Among them, the first partition plate 314, the second partition plate 315 and the third partition plate 316 as a whole present a T-shaped structure, so that the water tank 31 can be respectively separated into a ballast chamber 311, a drainage chamber 312 and an electrolysis chamber 313.

[0047] Specifically, in the present embodiment, as Figure 2 shown, the electrolysis element 35 is arranged in the electrolysis chamber 313, which can electrolyze the seawater in the electrolysis chamber 313 and transmit the electrolyzed hydrogen to the adjustment airbag 36 through the air duct 351. The adjustment airbag 36 is arranged at one end of the airship along its own length, which can finely adjust the pitching angle of the airship at this position, improving the applicability of the adjustment degree of the airship.

[0048] Furthermore, the materials required for the conventional hydrogen production principle by electrolyzing water are an electrolytic cell, electrodes, an electrolyte, a DC power supply, and a collection device. The electrolysis component 35 in this embodiment includes a DC power supply, two electrodes, and a collection device. The electrolytic cell in this embodiment can be the electrolysis chamber 313 of the water tank 31, which is used to hold seawater and provide a place for the electrode reaction. Electrodes generally use materials that are not easily oxidized, such as platinum, tungsten, or carbon rods, etc. Two electrodes are required and inserted into the electrolytic cell while maintaining an appropriate distance. The DC power supply can be set outside the box to ensure a certain safety performance, and then it provides the direct current required for electrolysis through wires. It can also be set at the top of the electrolysis chamber 313 of the box, at a certain distance from the seawater, to avoid interference and influence with the seawater. The collection device in this embodiment can be a conduit, which is used to collect the hydrogen generated near the electrodes. One end of the conduit is set near the electrodes, and the other end of the conduit is connected to the gas guide pipe 351. The conduit and the gas guide pipe 351 can also be integrated into one body.

[0049] Specifically, the operation steps of electrolysis are as follows: When seawater enters the electrolysis chamber 313, then operate the third control valve 3151 to close, and start the DC power supply, adjust the appropriate current intensity, and start the electrolysis process. The magnitude of the current depends on the reaction conditions and the size of the electrodes. As the electrolysis progresses, hydrogen will be generated on the cathode (negative electrode) and accumulate around the electrodes. At this time, the conduit will export and collect the hydrogen into the adjustment airbag 36. By supplementing the hydrogen in the adjustment airbag 36, the pitching attitude of the airship can be adjusted.

[0050] Specifically, in this embodiment, a fourth control valve is provided in the gas guide pipe 351, which can conduct and cut off the gas in the gas guide pipe 351. A gas flowmeter is also provided in the gas guide pipe 351, which can count the flow rate of hydrogen. The operator can supply the required gas according to the adjustment airbag 36, improving the reliability.

[0051] Furthermore, in this embodiment, as Figure 2 shown, a fifth control valve 3161 is provided on the third partition plate 316. When the adjustment airbag 36 urgently needs hydrogen supplementation, the output of the DC power supply will be increased. At this time, the electrolysis rate is faster, and the seawater will be consumed greatly. When the seawater is almost consumed, turn off the DC power supply, and open the fifth control valve 3161 and the third control valve 3151, which can supplement the seawater volume in the electrolysis chamber 313 at a high rate. Then close the fifth control valve 3161 and the third control valve 3151, and perform the electrolysis operation again.

[0052] Specifically, in this embodiment, as Figure 2As shown, the first partition plate 314, the second partition plate 315, and the third partition plate 316 are all vertically arranged, so that the positions of the ballast chamber 311, the drainage chamber 312, and the electrolysis chamber 313 are at the same horizontal plane, facilitating the seawater in the ballast chamber 311 to flow into the electrolysis chamber 313 or the drainage chamber 312, and improving the reliability.

[0053] In some embodiments of the present invention, as Figure 1 shown, there are two water tanks 31, each water tank 31 is provided with an electrolysis chamber 313, there are two adjustment air bags 36, and each electrolysis chamber 313 is connected to an adjustment air bag 36. In this embodiment, there are two water tanks 31 and two adjustment air bags 36. The two water tanks 31 are both connected to the bottom end of the airship body 10, and the two adjustment air bags 36 are respectively arranged at both ends of the accommodation space 11 along the length direction of the airship, and can respectively adjust the pitching angles of both ends of the airship body 10 along its own length direction, further improving the adjustability of the airship.

[0054] In some embodiments of the present invention, as Figure 2 shown, the ballast assembly 30 further includes a driving member, the driving member is arranged in the water tank 31, the water guide pipe includes a telescopic pipe 322 and a flexible pipe 321. One end of the flexible pipe 321 is connected to the driving pump 33, the other end of the flexible pipe 321 is connected to the telescopic pipe 322 through an opening, and the telescopic pipe 322 is connected outside the water tank 31 and connected to the driving member. The driving member can drive the telescopic pipe 322 to switch between the deployed state and the retracted state. In this embodiment, the driving member can be a motor or a cylinder. Due to its own flexible deformable characteristics, the flexible pipe 321 can connect the driving pump 33 and the telescopic pipe 322 without being affected by the environment, improving the reliability. The telescopic pipe 322 can be switched between the deployed state and the retracted state under the drive of the driving member, and can extend the length of the telescopic pipe 322, so that the airship can extend the telescopic pipe 322 into the seawater without being close to the sea level, improving the safety of the airship.

[0055] In addition, in this embodiment, the driving member is connected to the telescopic pipe 322 and can drive the telescopic pipe 322 to change between the deployed state and the retracted state. Among them, when the water suction pipe is in the deployed state, the driving member drives the telescopic pipe 322 to extend, so that the length of the water suction pipe reaches the maximum. When the water suction pipe is in the retracted state, the driving member drives the telescopic pipe 322 to contract, so that the length of the water suction pipe reaches the minimum. The setting of the driving member can make the extension and contraction of the telescopic pipe 322 automatic. Then, when the airship approaches the sea surface, it can automatically extend to suck seawater. When the seawater is sucked up, the telescopic pipe 322 is automatically retracted by the driving member.

[0056] In some embodiments of the present invention, as Figure 3As shown in the figure, the telescopic pipe 322 includes a plurality of telescopically arranged telescopic pipe parts 322 that are sleeved in sequence. The adjacent telescopic pipe parts 322 are slidably connected. Among the plurality of telescopic pipe parts 322, the one located on the outermost side in the radial direction of the telescopic pipe 322 is the first telescopic pipe part 3221, and the one located on the innermost side in the radial direction of the telescopic pipe 322 is the second telescopic pipe 322. The other end of the flexible pipe 321 is connected to one of the first telescopic pipe part 3221 and the second telescopic pipe part 3222, and the driving member is connected to the other of the first telescopic pipe part 3221 and the second telescopic pipe part 3222, and can drive it to move along the axial direction of the telescopic pipe 322. In this embodiment, when the water suction pipe is in the unfolded state, the driving member drives the plurality of telescopic pipe parts 322 to extend out respectively, so that the length of the water suction pipe reaches the maximum. When the water suction pipe is in the contracted state, the driving member drives the plurality of telescopic pipe parts 322 to contract respectively, so that the length of the water suction pipe reaches the minimum.

[0057] Specifically, in this embodiment, as Figure 3 shown, the first telescopic pipe part 3221 located on the outermost side in the radial direction of the telescopic pipe 322 is fixedly connected to the box body and is connected to the flexible pipe 321, and the second telescopic pipe part 3222 is connected to the driving member. The driving member in this embodiment can be a cylinder. The cylinder is connected to the second telescopic pipe part 3222 through a connecting rod. The connecting rod is an L-shaped structure and includes a connected first connecting part 3231 and a second connecting part 3232. The first connecting part 3231 and the second connecting part 3232 are perpendicularly arranged. The first connecting part 3231 is connected to the cylinder, and the second connecting part 3232 is connected to the second telescopic pipe part 3222.

[0058] When the telescopic pipe 322 is in the contracted state, as Figure 3 shown, the cylinder drives the second telescopic pipe part 3222 to move towards the sea level through the first connecting part 3231 and the second connecting part 3232 until the second telescopic pipe part 3222 enters the sea water, thereby realizing the sea water suction operation. When the sea water suction volume reaches the requirement, the driving member drives the second telescopic pipe part 3222 to move in a direction away from the sea water through the first connecting part 3231 and the second connecting part 3232. Since the second connecting part 3232 is perpendicularly arranged with respect to the second telescopic pipe part 3222, and since the second connecting part 3232 is connected to the second telescopic pipe part 3222, it can abut against the remaining telescopic pipe parts 322 and cause the remaining telescopic pipe parts 322 to also move in a direction away from the sea water until all the telescopic pipe parts 322 are contracted into the first telescopic pipe part 3221, that is, the contraction of the telescopic pipe 322 is completed.

[0059] Furthermore, a clamping claw is provided on the side of the second connecting part 3232 facing the second telescopic pipe part 3222, which can stably connect the second telescopic pipe part 3222 and improve the reliability.

[0060] Furthermore, in the present embodiment, an interference fit exists between multiple telescopic tube portions 322, which enables a certain amount of force to be applied between the multiple telescopic tube portions 322 to expand or contract, avoiding the situation where the telescopic tube 322 shakes when the airship moves.

[0061] Specifically, in the present embodiment, when the multiple telescopic tube portions 322 reach the deployed state, a limiting structure exists between adjacent telescopic tube portions 322, which enables adjacent telescopic tube portions 322 not to fall off, avoiding the situation where adjacent telescopic tube portions 322 fall off in the deployed state.

[0062] Furthermore, in the present embodiment, when the flight altitude of the airship is less than 50 meters below sea level, the telescopic tube 322 automatically unfolds, and seawater is sucked into the water tank 31 through the driving pump 33. The water injection volume of the water tank 31 is dynamically adjusted according to the ballast requirement calculated in real time, and the PID algorithm is used to optimize the water injection rate to avoid overcompensation.

[0063] In some embodiments of the present invention, as Figure 4 shown, a filter screen 32221 is provided inside the second telescopic tube portion 3222. In the present embodiment, the filter screen 32221 can prevent the telescopic tube 322 from sucking in marine organisms or impurities, thereby avoiding the blockage of the telescopic tube 322.

[0064] In some embodiments of the present invention, two driving pumps 33 are provided. One end of each of the two driving pumps 33 is connected to the water tank 31, and the other end of each of the two driving pumps 33 is connected to the water guide pipe. In the present embodiment, the provision of the two driving pumps 33 can prevent the situation where the ballast assembly 30 of the airship cannot be used when one driving pump 33 fails. The provision of the two driving pumps 33 enables the use of the other driving pump 33 for operation after one driving pump 33 fails, improving the reliability. The airship is equipped with a dual-driving pump 33 redundant structure to ensure that the ballast operation can still be performed in case of a single-point failure.

[0065] In some embodiments of the present invention, an anti-corrosion coating is applied to the inner wall surface of the water tank 31. In the present embodiment, through nanocoating and material optimization, a graphene-based anti-corrosion coating is sprayed on the inner wall of the water tank 31, and the flexible tube 321 and the telescopic tube 322 are made of salt spray-resistant titanium alloy.

[0066] In some embodiments of the present invention, a weight sensor is provided on the hull 10, which can monitor the change in the cargo load of the airship in real time, and calculate the required compensating ballast weight in combination with the airship altitude and acceleration data.

[0067] In some embodiments of the present invention, the water levels in the ballast chamber 311, the drainage chamber 312, and the electrolysis chamber 313 in the water tank 31 are monitored in real time and displayed through the airship control interface, supporting the manual / automatic mode switch.

[0068] In some embodiments of the present invention, an attitude sensor is further provided on the airship based on seawater ballast compensation, which can obtain the attitude characteristics of the airship in real time, and can adjust the pitch and weight in real time by adjusting the airbag 36 and the water tank 31.

[0069] The airship based on seawater ballast compensation in the present invention combines the real-time feedback of the airship attitude sensor and seawater collection to achieve precise adjustment of the ballast weight, uses seawater to replace traditional ballast, reduces operating costs, and avoids environmental pollution. After the airship jettisons goods at sea, it can quickly suck in seawater from the sea surface to compensate for the ballast, without having to return to land for replenishment. When it can cooperate with ships, the onboard equipment can assist in water injection to improve efficiency. Secondly, seawater is cost-free, reducing the system operation and maintenance costs by more than 60% compared with traditional ballast methods. Thirdly, seawater can be recycled to produce hydrogen and oxygen, and the hydrogen can be recycled. Finally, the redundantly designed drive pump 33 can ensure that a single-point failure does not affect the overall function.

[0070] Furthermore, a controller and a main power supply are also provided on the airship based on seawater ballast compensation. The controller is electrically connected to the first control valve 3141, the second control valve, the third control valve 3151, and the fourth control valve respectively, and can control the on-off states of the above control valves respectively. The controller is also electrically connected to the drive pump 33, the drive member, and the electrolysis member 35, and can control the above electrical components to operate respectively. The main power supply is electrically connected to the electrolysis member 35, the drive pump 33, the drive member, the first control valve 3141, the second control valve, the third control valve 3151, and the fourth control valve respectively, and can provide power for the above components.

[0071] Specifically, in this embodiment, the first control valve 3141, the second control valve, the third control valve 3151, and the fourth control valve are all solenoid valves, which have a simple structure and are easy to install and maintain. The design of solenoid valves is usually relatively simple, with a compact structure and convenient installation. Since the solenoid valve has a simple structure, it is relatively easy to maintain, which can significantly reduce the operating costs of enterprises. In addition, the solenoid valve has a fast response speed and quick action, improving the operation efficiency.

[0072] Furthermore, the operation process of the airship based on seawater ballast compensation in the present invention is as follows: The weight sensor on the airship detects the weight of the airship in real time. When the airship jettisons goods to the cargo ship and its own weight decreases, at this time, when the weight sensor detects the weight decrease, it will first control the airship to descend to below 50 meters from the sea surface, and then control the drive member to start and drive the second telescopic pipe part 3222 to move towards the sea surface until the second telescopic pipe part 3222 enters the seawater, and then start the drive pump 33 to suck seawater through the flexible pipe 321 and the telescopic pipe 322.

[0073] When the seawater fills the ballast chamber 311 and reaches the limit of the airship weight balance, the operation of the driving pump 33 is shut down. Then, the driving member drives the second telescopic tube portion 3222 to contract through the connecting rod, and due to the abutment of the connecting rod, a plurality of telescopic tube portions 322 contract until the telescopic tube 322 reaches the contracted state.

[0074] When the seawater fills the ballast chamber 311, the controller can open the first control valve 3141 so that the drainage chamber 312 is also filled with seawater. When emergency drainage is required, drainage can be carried out simultaneously through the driving pump 33 and the air pump 34, improving the drainage efficiency.

[0075] When the front and rear postures of the airship need to be adjusted and the gas in the adjustment airbag 36 is insufficient, the controller can open the third control valve 3151 so that the electrolysis chamber 313 is also filled with seawater. Then, through the power supply of the electrolysis member 35 by the main power supply, the seawater in the electrolysis chamber 313 can be electrolyzed to generate hydrogen and oxygen. The hydrogen generated near the electrode can be collected by the conduit and transmitted to the adjustment airbag 36 through the air duct 351. In this embodiment, there are two water tanks 31 and adjustment airbags 36. The two adjustment airbags 36 are respectively arranged at the front and rear positions of the airship. When the airbag at the front position or the airbag at the rear position needs to be supplemented with gas, the electrolysis member 35 can be powered for the corresponding water tank 31.

[0076] When the airship takes in goods from the cargo ship and its own weight increases, at this time, the weight sensor detects the weight increase, and then drainage is required. At this time, the controller controls the driving pump 33 to start, so that the seawater in the ballast chamber 311 is discharged through the flexible tube 321 and the telescopic tube 322. At the same time, the second control valve at the drainage hole is opened, and the air pump 34 is turned on to quickly discharge the seawater in the drainage chamber 312, improving the drainage efficiency.

[0077] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
