Technical Field

[0001] The present invention belongs to the technical field of aerostatic devices, and particularly relates to an airship based on cargo replacement 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. Low-altitude airships have the advantages of large load capacity and long endurance in logistics transportation. However, the weight change during cargo loading and unloading can easily lead to buoyancy imbalance and affect flight stability. Summary of the Invention

[0035] 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. Low-altitude airships have the advantages of large payload and long endurance in logistics transportation. However, the weight change during cargo loading and unloading can easily lead to buoyancy imbalance and affect flight stability.

[0036] Figure 1A partial cross-sectional view of an airship based on goods replacement compensation according to an embodiment of the present invention is schematically shown. As Figure 1 shown, the present invention provides an airship based on goods replacement compensation. The airship in the present invention includes a hull 10, an airbag, and a cargo hold 20. There is an accommodation space 11 inside the hull 10. The airbag is arranged in the accommodation space 11. The cargo hold 20 is connected to the bottom end of the hull 10. There is an article placement cavity 21 and a ballast cavity 22 inside the cargo hold 20. The ballast cavity 22 and the article placement cavity 21 are arranged at intervals along the height direction of the hull 10. At least one side of the article placement cavity 21 along the length direction of the hull 10 has a first opening. At least one side of the ballast cavity 22 along the length direction of the hull 10 has a second opening.

[0037] By using the airship based on goods replacement compensation in the present technical solution, the airbag can provide buoyancy for the hull 10 to ensure the floating state of the airship. Goods can enter or be removed from the article placement cavity 21 of the cargo hold 20 through the first opening, so that the airship has the characteristic of transferring goods. Ballast members can enter or be removed from the ballast cavity 22 of the cargo hold 20 through the second opening. When the airship unloads goods, ballast members need to be placed in the ballast cavity 22. When the airship loads goods, the ballast members in the ballast cavity 22 need to be taken out to ensure the overall weight of the airship remains unchanged and the balance of buoyancy, thereby realizing the stability of the airship floating.

[0038] Specifically, in the present embodiment, the ballast cavity 22 can be located at the bottom end of the article placement cavity 21, or the ballast cavity 22 can be located at the top end of the article placement cavity 21. The upper and lower layer arrangement can ensure that when the ballast cavity 22 and the article placement cavity 21 load and unload ballast members and goods respectively, due to the different heights of the ballast cavity 22 and the article placement cavity 21, the ballast members and goods will not interfere with each other, improving the reliability.

[0039] Furthermore, in the present invention, the cargo hold 20 is of a square structure, and both the article placement cavity 21 and the ballast cavity 22 are also square spaces. Therefore, in this embodiment, the goods and ballast members need to have a structure with a flat bottom surface. The goods with a flat bottom surface can enter the article placement cavity 21 through the first opening and remain stable. The ballast members with a flat bottom surface can enter the ballast cavity 22 through the second opening and remain stable.

[0040] Specifically, in the present embodiment, the goods can be of various types. The typical cargo capacity of an airship ranges from several hundred kilograms to several tons. The goods need to be adapted to the internal space of the airbag (usually suitable for bulk or modular equipment). Secondly, it is necessary to avoid transporting flammable, explosive and dangerous goods (although helium is safe, electronic equipment requires explosion-proof design). In addition, it is suitable for goods with small batches, high added value or low time limit requirements. Bulk logistics still relies on traditional transportation. By combining its advantages of staying in the air and precise transportation ability, the airship is becoming an effective supplement to traditional transportation methods.

[0041] Specifically, in this embodiment, the ballast can be a liquid ballast, such as water. Water is commonly used as a ballast in traditional airships. In this embodiment, water can be injected into or discharged from a square water tank that holds water through a water pump, thereby adjusting the weight of the airship. Water is easily obtainable, low in cost, and flexible in adjustable quantity. Additionally, the ballast can also be a solid ballast, such as iron sand or iron pellets, which are commonly used in modern airships because of their high density and ease of being thrown by mechanical devices. The iron sand or iron pellets in this embodiment can also be loaded into a directional box to ensure stability within the ballast cavity 22.

[0042] In some embodiments of the present invention, as Figure 3 and 4 shown, roller groups, a conveyor belt 231, and a first driving member are provided in both the ballast cavity 22 and the storage cavity 21. The conveyor belt 231 is wrapped around the roller groups, and the first driving member is connected to the roller groups and can drive the conveyor belt 231 to move along the length direction of the airship body 10 through the roller groups. In this embodiment, when the dimension of the storage cavity 21 along the length direction of the airship body 10 is relatively long, it is necessary for the operator to first enter the storage cavity 21 and then place or remove the goods in sequence. Similarly, when the dimension of the ballast cavity 22 along the length direction of the airship body 10 is relatively long, it is necessary for the operator to first enter the ballast cavity 22 and then place or remove the ballast in sequence, which not only consumes a large amount of the operator's physical strength but also reduces the loading and unloading efficiency of the goods and the ballast.

[0043] Specifically, in the present invention, a conveying assembly 23 is respectively provided in the storage cavity 21 and the ballast cavity 22. The conveying assembly 23 includes roller groups, a conveyor belt 231, and a first driving member. The first driving member can be a component such as a motor that drives the roller groups to rotate. The first driving member drives the roller groups to rotate. Since the conveyor belt 231 is wrapped around the outside of the roller groups, it can drive the conveyor belt 231 through friction, thereby enabling the conveyor belt 231 to move along the length direction of the airship body 10, so that the goods can enter or exit the storage cavity 21, or the ballast can enter or exit the ballast cavity 22.

[0044] Specifically, as Figure 4 shown, a plurality of conveying assemblies 23 can be provided along the width direction of the airship body 10, and the plurality of conveying assemblies 23 are arranged at intervals, capable of accommodating more ballast or goods.

[0045] Specifically, in this embodiment, as Figure 3As shown in the figure, the roller group includes a plurality of rollers 232 arranged along the length direction of the hull 10. The plurality of rollers 232 are arranged at intervals. The conveyor belt 231 is wrapped outside the plurality of rollers 232, and the outer surface of each roller 232 is in contact with the inner surface of the conveyor belt 231. The combined structure of the plurality of rollers 232 can increase the friction force between the roller group and the conveyor belt 231, thereby achieving the purpose of the roller group stably driving the conveyor belt 231 to convey along the length direction of the hull 10, and improving the reliability.

[0046] Specifically, in this embodiment, the conveying assembly 23 further includes a bracket. The bracket is arranged in the storage cavity 21 and the ballast cavity 22, and is rotationally connected to the roller group, and can respectively support the conveying assembly 23 in the storage cavity 21 and the conveying assembly 23 in the ballast cavity 22, and support the rotation of the roller group.

[0047] The bracket in this embodiment includes a support plate, a first connecting plate, a second connecting plate and a connecting member. The support plate is placed at the bottom end of the storage cavity 21 or the ballast cavity 22. One end of the first connecting plate and one end of the second connecting plate are respectively connected to the opposite sides of the support plate. The other end of the first connecting plate and the other end of the second connecting plate are connected by a connecting member. The connecting member is arranged through the roller 232, and the roller 232 is rotatably connected to the connecting member.

[0048] Specifically, a bearing is arranged between the roller 232 and the connecting member. The main function of the bearing is to support the roller 232 and reduce the mechanical load friction coefficient of the roller 232 during the transmission process. This supporting effect ensures the stability and balance of the roller 232. Secondly, the bearing makes the rotation smoother by reducing the friction between the rotating roller 232 and the connecting member, reduces the energy consumption, and can significantly improve the mechanical efficiency. The bearing can also effectively prevent the connecting member from being damaged due to the force, and keep the rotating roller 232 in the correct position. This protective effect prolongs the service life of the machine. Finally, the bearing ensures the accuracy and stability of the machine by reducing friction and wear.

[0049] Furthermore, in this embodiment, the connecting members can be arranged in multiple numbers. The number of the multiple connecting members is the same as that of the rollers 232. Each connecting member is arranged through one roller 232. Using multiple connecting members can increase the supporting area between the roller group and the connecting members, thereby increasing the supporting force for the roller group and the conveying assembly 23, and further improving the supporting performance of the bracket for the conveying assembly 23.

[0050] In some embodiments of the present invention, such as Figure 3 and 4As shown, a plurality of storage plates 2311 are provided on the outer surface of the conveyor belt 231. The plurality of storage plates 2311 are arranged at intervals along the driving direction of the conveyor belt 231. The storage plate 2311 includes a first magnetic member 2312, and the first magnetic member 2312 is used for magnetically connecting with the ballast or the goods. In this embodiment, the storage plate 2311 is fixedly connected to the conveyor belt 231. Each storage plate 2311 is used to place one piece of goods or ballast. A first magnetic member 2312 is provided on the storage plate 2311. The goods or ballast are iron parts, or a second magnetic member is provided on the goods / ballast. The first magnetic member 2312 can perform magnetic attraction operation on the goods or ballast, so as to ensure the stability of the goods or ballast when the airship moves.

[0051] Specifically, in this embodiment, when the airship unloads goods, the conveying component 23 of the storage cavity 21 can convey the goods on the conveyor belt 231 towards the first opening through the first driving member, and the operator at the first opening takes them. Then, the conveying component 23 in the ballast cavity 22 is moved in the direction opposite to that of the storage cavity 21, so that the operator at the first opening conveys the ballast into the ballast cavity 22 through the conveying component 23, thereby achieving weight balance. When the airship loads goods, the conveying component 23 of the storage cavity 21 can convey the goods on the conveyor belt 231 in the direction away from the first opening through the first driving member. The operator at the first opening places the goods on the conveying component 23 to complete the loading of the goods. Then, the conveying component 23 in the ballast cavity 22 is moved in the direction opposite to that of the storage cavity 21, so that the operator at the first opening takes out the ballast in the ballast cavity 22, thereby achieving weight balance.

[0052] Specifically, in this embodiment, after the loading and unloading tasks are completed, the conveying components 23 of the storage cavity 21 and the ballast cavity 22 can stop operating, so that the ballast and the goods are both placed upright on the conveyor belt 231. In addition, when there are more goods or ballast, some goods or ballast will be under the conveyor belt 231, causing the goods or ballast to be inverted. However, due to the magnetic attraction operation between the goods and the first magnetic member 2312 on the conveyor belt 231, and the magnetic attraction operation between the ballast and the first magnetic member 2312 on the conveyor belt 231, the connection force between the goods and the storage plate 2311 and between the ballast and the storage plate 2311 will be stronger, and the situation where the goods break away from the storage plate 2311 and the ballast breaks away from the storage plate 2311 will not occur.

[0053] In some embodiments of the present invention, such as Figure 3 and 4As shown, a first claw body 2313 and a second claw body 2314 are provided on the storage plate 2311. The first claw body 2313 and the second claw body 2314 are symmetrically arranged on opposite sides of the first magnetic member 2312, and the first claw body 2313 and the second claw body 2314 can move relative to each other. In this embodiment, a third driving member is further provided on the storage plate 2311. The third driving member can be a component such as a cylinder that drives the first claw body 2313 and / or the second claw body 2314. The third driving member can be connected to the storage plate 2311, and is connected to the first claw body 2313 and / or the second claw body 2314, and can make the first claw body 2313 and the second claw body 2314 move relative to each other. Since the goods or ballast can be magnetically attracted to the first magnetic member 2312, the first claw body 2313 and the second claw body 2314 can clamp the goods or ballast that have been magnetically attracted between them, thereby further improving the stability of the goods or ballast and enhancing the reliability.

[0054] Specifically, in this embodiment, a first slide rail 32 and a second slide rail 32 are provided on the storage plate 2311. The first claw can slide on the first slide rail 32 driven by the third driving member, and / or the second claw can slide on the second slide rail 32 driven by the third driving member. The settings of the first slide rail 32 and the second slide rail 32 can improve the accuracy of the movement of the first claw and the second claw.

[0055] Further, in this embodiment, hooks can be provided on the goods and ballast, and slots can be provided on the storage plate 2311. The hooks are clamped in the slots, which can also fix the goods and the storage plate 2311 and the ballast and the storage plate 2311, and improve the stability of the goods and ballast on the conveyor belt 231.

[0056] Specifically, in this embodiment, slots can be provided on the goods and ballast, and hooks can be provided on the storage plate 2311. The hooks are clamped in the slots, which can also fix the goods and the storage plate 2311 and the ballast and the storage plate 2311, and improve the stability of the goods and ballast on the conveyor belt 231.

[0057] In some embodiments of the present invention, a first door body is provided on at least one side of the cargo hold 20 along the length direction of the hull 10. The first door body is rotatably connected to the cargo hold 20 to cover the first opening. In this embodiment, when the operator needs to load goods into the storage cavity 21, the first door body is rotatably connected to the cargo hold 20, which can open the first opening, thereby facilitating the operator to load the goods. When the operator finishes loading the goods in the storage cavity 21, the first opening can be covered by the first door body, thereby realizing the sealing of the storage cavity 21.

[0058] Specifically, in this embodiment, the cargo hold 20 is provided with a second door body on at least one side along the length direction of the hull 10, and the second door body is rotatably connected to the cargo hold 20 to cover the second opening. When the operator needs to load the ballast parts into the ballast cavity 22, the second door body is rotatably connected to the cargo hold 20, so that the second opening can be opened, thereby facilitating the operator to load the ballast parts. When the operator has finished loading the ballast parts into the ballast cavity 22, the second opening can be covered by the second door body, thereby achieving sealing of the ballast cavity 22.

[0059] Specifically, in this embodiment, a first seal is provided between the first door body and the first opening, and a second seal is provided between the second door body and the second opening. Both the first seal and the second seal are sealing rings, which have good sealing performance within the working pressure and a certain temperature range, and as the pressure increases, the sealing performance can be automatically improved to ensure the sealing performance of the storage chamber 21 and the ballast chamber 22, to ensure that the ballast will not detach from the ballast chamber 22, and to ensure that the cargo will not detach from the storage chamber 21.

[0060] In some embodiments of the present invention, Figure 1 As shown, the airship based on cargo replacement compensation also includes a ballast assembly, which includes a slide rail 32, a second driving member and a ballast component 31. The slide rail 32 is arranged in the accommodating space 11 and extends along the length direction of the hull 10. The ballast component 31 is slidably connected to the slide rail 32. The second driving member is connected to the ballast component 31 and can drive the ballast component 31 to move along the length direction of the hull 10. In this embodiment, the airship can not only perform ballast compensation through the ballast component of the ballast chamber 22, but also perform ballast compensation for the entire airship through the ballast component 31 on the slide rail 32, further improving the ballast efficiency of the airship.

[0061] Specifically, in this embodiment, the second driving member can be a component such as a cylinder that drives the ballast component 31 to move along the length direction of the hull 10. The second driving member drives the ballast component 31 to move on the slide rail 32, so that the center of gravity of the hull 10 moves, thereby adjusting the posture of the entire airship and improving the adjustability.

[0062] Furthermore, in the present embodiment, a plurality of ballast components 31 may be provided, and the ballast components 31 are magnetic components. The plurality of ballast components 31 can be connected to each other by magnetic force. The second driving component moves one ballast component 31, and due to the effect of the magnetic force, it can drive the plurality of ballast components 31 to move. The structure of adopting a plurality of ballast components 31 can increase the ballast weight, thereby improving the ballast compensation amount of the airship.

[0063] In some embodiments of the present invention, Figure 2As shown, at least one side of the hull 10 along its length direction is provided with a third door body, and at least one side of the accommodation space 11 along the length direction of the hull 10 is provided with a third opening. The third door body is rotatably connected to the hull 10 to cover the third opening, and the ballast component 31 can enter or exit the accommodation space 11 through the third opening. In this embodiment, when the airship unloads goods, the operator can supplement the ballast through the second opening towards the ballast chamber 22. If the compensation value of the ballast chamber 22 reaches the maximum, the operator can also place the ballast component 31 on the slide rail 32 through the third opening, so that weight compensation can be carried out from multiple positions of the airship. When the airship loads goods, the operator can take out the ballast from the ballast chamber 22 through the second opening. If the ballast in the ballast chamber 22 has been emptied, the operator can also take out the ballast component 31 from the slide rail 32 through the third opening, and weight compensation can be carried out from multiple positions on the airship.

[0064] Specifically, in this embodiment, when the operator needs to load the ballast component 31 into the accommodation space 11, the third door body is rotatably connected to the cargo hold 20, which can open the third opening, facilitating the operator to load the ballast component 31. When the operator finishes loading the ballast component 31 in the accommodation space 11, the third opening can be covered by the third door body, thereby realizing the sealing of the accommodation space 11.

[0065] Specifically, in this embodiment, double-layer sealing rings and air pressure balance valves are adopted between the first door body and the first opening, between the second door body and the second opening, and between the third door body and the third opening to ensure stable air pressure during the loading and unloading process.

[0066] In some embodiments of the present invention, as Figure 2 shown, at least one side of the hull 10 along its width direction is provided with a liquid storage container 40. The top end of the liquid storage container 40 is provided with a liquid inlet, the bottom end of the liquid storage container 40 is provided with a liquid outlet, and a control valve is arranged in the liquid outlet. In this embodiment, when the airship unloads goods, the operator can supplement the ballast through the second opening towards the ballast chamber 22. If the compensation value of the ballast chamber 22 reaches the maximum, the operator can also fill the liquid storage container 40 with liquid water through the liquid inlet to complete weight compensation, and weight compensation can be carried out from multiple positions of the airship. When the airship loads goods, the operator can take out the ballast from the ballast chamber 22 through the second opening. If the ballast in the ballast chamber 22 has been emptied, the operator can also discharge the liquid water from the liquid storage container 40 through the liquid outlet, and weight compensation can be carried out from multiple positions on the airship.

[0067] Specifically, in this embodiment, a control valve is also arranged at the liquid inlet. Cooperating with the control valve at the liquid outlet, it can ensure the sealing performance of the liquid storage container 40 and can realize the accurate operation of the control valve under the control of the airship.

[0068] Specifically, in this embodiment, a driving pump may also be provided in the liquid storage container 40. One end of the driving pump is communicated with one end of the first pipe body, and the other end of the second pipe body passes through the liquid inlet and is communicated with an external liquid source, for sucking liquid water from the outside into the liquid storage container 40. In other embodiments, two driving pumps are provided. One ends of the two driving pumps are both communicated with the liquid storage container 40, and the other ends of the two driving pumps are both communicated with the first pipe body. The arrangement of the two driving pumps can avoid the situation that the liquid storage container 40 cannot be filled with liquid when one driving pump fails. The arrangement of the two driving pumps can use the other driving pump for operation after one driving pump fails, improving the reliability. The airship is equipped with a dual-driving pump redundancy structure to ensure that the ballast operation can still be carried out in case of a single-point failure.

[0069] Furthermore, a controller and a main power supply are also provided on the airship. The controller is electrically connected to the control valves at the liquid inlet and the liquid outlet, and can respectively control the on-off states of the above control valves. The controller is also electrically connected to the first driving member, the second driving member and the third driving member, and can respectively control the above electrical components to operate. The main power supply is electrically connected to the first driving member, the second driving member, the third driving member and the control valve, and can supply power to the above components.

[0070] Specifically, in this embodiment, the control valve is a solenoid valve, which has a simple structure and is easy to install and maintain. The design of the solenoid valve 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 cost of the enterprise. In addition, the solenoid valve has a fast response speed and quick action, improving the operation efficiency.

[0071] In some embodiments of the present invention, an attitude sensor is also provided on the airship, which can obtain the attitude characteristics of the airship in real time and can perform real-time pitch and weight adjustment by moving the ballast member 31.

[0072] In some embodiments of the present invention, a weight sensor is provided at the bottom of the cargo hold 20, which can monitor the change of the airship's cargo load in real time and calculate the required compensating ballast weight in combination with the airship height and acceleration data. The gravity sensor is a sensor that can detect the acceleration or gravity change of an object. Its core function is to sense the motion state of the device by measuring the static gravity direction or dynamic acceleration. The gravity sensor is usually based on a microelectromechanical system and contains a tiny mass block and a detection circuit inside. When the device accelerates or tilts, the displacement of the mass block changes the capacitance or resistance value, which is converted into an electrical signal by the circuit and output.

[0073] In some embodiments of the present invention, a buoyancy sensor is provided at the top of the hull 10. A buoyancy sensor is a device that can detect changes in the buoyancy force exerted on an object in a gas. Its core function is to monitor parameters such as density and volume by sensing buoyancy differences, or to control the buoyancy state of a device. The buoyancy sensor in this embodiment is used to monitor the buoyancy of the airship and control the flight altitude in combination with the ballast system.

[0074] Further, the operation process of the airship based on cargo replacement compensation in this embodiment is as follows: When the airship unloads goods, the first door body is opened, and the operator waits at the first opening for the goods delivered by the conveying component 23. At this time, the weight sensor will detect the weight of the airship in real time. After unloading is completed, the second door body is opened according to the unloading weight, and the corresponding ballast is supplemented on the conveying component 23 in the ballast chamber 22. After the ballast compensation is completed, the first door body and the second door body are closed. Among them, if the weight compensation by only the ballast in the ballast chamber 22 is not enough, liquid water can be injected into the liquid storage container 40 to further increase the weight. If the ballast of both the ballast chamber 22 and the liquid storage container 40 does not meet the requirements, the third door body can also be opened to add ballast components 31 to the slide rail 32 to complete the ballasting operation of the airship again.

[0075] When the airship loads goods, the first door body is opened, and the operator places goods on the conveying component 23 at the first opening. At this time, the weight sensor will detect the weight of the airship in real time. After loading is completed, the second door body is opened according to the loading weight, and the corresponding ballast is taken out from the ballast chamber 22. After the ballast compensation is completed, the first door body and the second door body are closed. Among them, if the weight compensation by only the ballast in the ballast chamber 22 is not enough, the liquid water can be drained from the liquid storage container 40 to further reduce the weight. If the ballast of both the ballast chamber 22 and the liquid storage container 40 does not meet the requirements, the third door body can also be opened to reduce the number of ballast components 31 on the slide rail 32 to complete the ballasting operation of the airship again.

[0076] Low-altitude airships have the advantages of large load capacity and long endurance in logistics transportation. However, the weight change during cargo loading and unloading can easily lead to buoyancy imbalance and affect flight stability. In the prior art, airships mostly rely on fixed ballast or manual adjustment, and there are the following problems: low efficiency of cargo loading and unloading, lack of an automated rapid replacement mechanism. The ballast compensation response lags, which is likely to cause attitude out of control. The system compatibility is poor, and it is difficult to adapt to different specifications of goods and airship models.

[0077] In view of the problems existing in the existing low-altitude logistics transportation technology, such as low efficiency of cargo loading and unloading, difficulty in maintaining dynamic buoyancy balance, and poor system compatibility, an airship with an integrated system is proposed. By designing an integrated rapid cargo loading and unloading mechanism, a dynamic ballast compensation module, and an intelligent control unit, efficient cargo access, real-time weight adjustment, and optimization of flight attitude stability are achieved. First, the conveyor component 23 is adopted to accelerate the loading and unloading process of the cargo and the ballast, thus improving the operation efficiency and reducing the labor cost. Second, the combination of the movable ballast component 31 and the liquid storage container 40 is used to make real-time adjustments according to the data fed back by the weight sensor and the buoyancy sensor, keeping the total weight of the airship constant, and further enhancing the buoyancy balance and attitude control capabilities during flight. In addition, the intelligent control unit based on the PID algorithm can dynamically optimize the compensation strategy to ensure that the airship can maintain the best flight state under various conditions. More importantly, the modular design is adopted in the present invention, enabling the system to quickly adapt to different specifications of cargo and airship models, greatly expanding its application scenarios, and providing the possibility to meet diverse mission requirements. This not only improves the operation flexibility and adaptability of the airship but also facilitates daily inspection and maintenance, effectively reducing the downtime and maintenance cost.

[0078] In summary, the present invention not only significantly improves the cargo loading and unloading efficiency and flight performance of the low-altitude airship but also provides solid technical support for its wide application in fields such as meteorological observation, environmental monitoring, and communication relay. Its innovative design concept and practical application value indicate that it has broad development prospects in the future low-altitude logistics transportation field.
