Description

Technical Field

[0001] The present invention relates to the technical field of aircraft, and in particular to a cargo airship and an airship transportation method. Background Art

[0002] With the development of science and technology, more and more aircraft are used, and cargo airship is one of them, which is used to transport goods.

[0003] In the prior art, cargo airships usually rely on their own buoyancy and upward aerodynamic force to enable them to take off; however, in extreme situations such as energy shortage and engine failure, such cargo airships will lose power, resulting in the risk of falling, which not only reduces transportation efficiency but also poses a major threat to ground facilities and personnel safety.

[0004] Therefore, how to ensure the high-altitude transportation function of the cargo airship while preventing the cargo airship from falling during transportation, thereby improving transportation efficiency and ensuring the safety of ground facilities and personnel has become a technical problem that needs to be solved urgently in this field. Summary of the invention

[0005] The purpose of the present invention is to at least solve the technical problem of how to ensure the high-altitude transportation function of the cargo airship while preventing the cargo airship from falling during transportation, thereby improving transportation efficiency and ensuring the safety of ground facilities and personnel. This purpose is achieved through the following technical solutions:

[0006] In a first aspect, the present invention proposes a cargo airship, comprising: a main capsule, in which a containing cavity is provided, the containing cavity contains working gas, and the working gas is used to provide net buoyancy to the cargo airship as a whole; a cabin, installed on the outer wall of the main capsule, and the cabin is used to carry cargo; a horizontal drive device, installed on the outer wall of the main capsule, and the horizontal drive device is used to provide horizontal thrust to the cargo airship as a whole; and a vertical drive device, installed on the outer wall of the main capsule, and the vertical drive device is used to provide vertical downward thrust to the cargo airship as a whole, and the vertical drive device can adjust the magnitude of the downward thrust so that the cargo airship satisfies during transportation: F>G; the cargo airship can satisfy during transportation: F=G+f; in the above two formulas, F is the net buoyancy, G is the sum of the weight of the cargo airship and the weight of the cargo carried by the cabin, and f is the downward thrust.

[0007] In this cargo airship, since the net buoyancy of the cargo airship as a whole during transportation is greater than the sum of the weight of the cargo airship and the weight of the cargo carried by the cabin, that is, F>G, it means that before the vertical drive device works, the cargo airship and the cargo as a whole are subjected to an upward force in the vertical direction, thereby enabling the cargo airship to rise. Then, by starting the vertical drive device, a vertical downward thrust is applied to the cargo airship as a whole to balance the forces on the cargo airship in the vertical direction, that is, F=G+f; and the horizontal drive device can be used to provide a horizontal thrust to the cargo airship as a whole to achieve the transportation of the cargo airship; finally, after the cargo airship is transported to the destination, the altitude of the cargo airship is lowered by increasing the downward thrust or reducing the net buoyancy, and finally the cargo can be unloaded. Therefore, this cargo airship can realize the basic functionality of high-altitude transportation, and because the net buoyancy of the cargo airship as a whole during transportation is greater than the sum of the weight of the cargo airship and the weight of the cargo carried by the cabin, even in extreme situations such as insufficient energy or failure of the vertical drive device, the cargo airship will not fall but will float upward, thereby ensuring the safety of ground facilities and personnel.

[0008] In some embodiments of the present invention, the overall capsule includes a first capsule and a second capsule connected to the first capsule, and the first capsule and the second capsule are symmetrically arranged relative to the cabin.

[0009] In some embodiments of the present invention, the vertical driving device includes a first vertical driving sub-device and a second vertical driving sub-device, the first vertical driving sub-device is installed on the outer wall of the first capsule, and the second vertical driving sub-device is installed on the outer wall of the second capsule.

[0010] In some embodiments of the present invention, the first vertical driving sub-device and the second vertical driving sub-device are symmetrically arranged relative to the overall capsule.

[0011] In some embodiments of the present invention, the first vertical driving sub-device is a first vector motor, and the second vertical driving sub-device is a second vector motor.

[0012] In some embodiments of the present invention, the horizontal driving device includes a plurality of horizontal driving sub-devices, and the plurality of horizontal driving sub-devices are evenly spaced and arranged on the main capsule.

[0013] In some embodiments of the present invention, the overall capsule includes a head and a tail, and the cargo airship also includes a tail wing connected to the outer wall of the tail of the overall capsule, and the tail wing is used to enhance the stability of the cargo airship as a whole during transportation.

[0014] In some embodiments of the present invention, the cargo airship also includes: an avionics measurement and control device for recording and adjusting the flight status of the cargo airship and realizing data transmission with the ground; an energy storage battery installed in the cabin, the energy storage battery is used to power the entire cargo airship; and a solar panel installed on the outer wall of the total capsule, the solar panel is used to charge the energy storage battery.

[0015] In a second aspect, the present invention proposes an airship transportation method, which is applicable to any of the above-mentioned cargo airships, and is characterized in that the airship transportation method comprises: step S100: loading cargo on the cabin of the cargo airship, and satisfying that the net buoyancy F is greater than the sum of the weight of the cargo airship and the weight of the cargo carried by the cabin G, and after the cargo loading is completed, the cargo airship is made to rise; step S200: the cargo airship starts the vertical drive device in the ascending state, so that the cargo airship as a whole is subjected to a downward thrust f, until F=G+f is satisfied, so that the airship as a whole and the cargo are subjected to force balance in the vertical direction; step S300: the cargo airship flies to the sky above the destination, the cargo airship descends in the vertical direction to a preset distance from the ground of the destination, and unloads the cargo.

[0016] In some embodiments of the present invention, step S300 specifically includes: step S301: after the cargo airship flies to the sky above the destination, the cargo airship is descended by increasing the downward thrust or reducing the net buoyancy until the cargo airship is a preset distance from the ground of the destination in the vertical direction; step S302: unloading the cargo and driving the vertical drive device to increase the downward thrust at the same time so that the cargo airship is subjected to force balance in the vertical direction.

[0037] Figure 1 A schematic diagram of the structure of a cargo airship provided by an embodiment of the present invention; Figure 2 The force analysis diagram of the cargo airship provided by the embodiment of the present invention; Figure 1 and Figure 2 As shown, the embodiment of the present invention provides a cargo airship 100, comprising: a main capsule 1000, which is provided with a containing cavity, the containing cavity contains working gas, and the working gas is used to provide a net buoyancy F for the cargo airship 100 as a whole; a cabin 2000, which is installed on the outer wall of the main capsule 1000, and the cabin 2000 is used to carry cargo; a horizontal driving device 3000, which is installed on the outer wall of the main capsule 1000, and the horizontal driving device 3000 is used to provide a thrust in the horizontal direction for the cargo airship 100 as a whole; and a vertical driving device 4000, which is installed on the outer wall of the main capsule 1000, and the vertical driving device 4000 is used to provide a vertical downward thrust f for the cargo airship 100 as a whole, and the vertical driving device 4000 can adjust the magnitude of the thrust f so that

[0038] During the transportation process, the cargo airship 100 satisfies: F>G;

[0039] The cargo airship 100 can satisfy the following conditions during transportation: F = G + f;

[0040] In the above two formulas, F is the net buoyancy, G is the sum of the weight of the cargo airship 100 and the weight of the cargo carried by the cabin 2000, and f is the downward thrust.

[0041] In this embodiment, since the net buoyancy F received by the cargo airship 100 as a whole during transportation is greater than the sum G of the weight of the cargo airship 100 and the weight of the cargo carried by the cabin 2000, that is, F>G, it means that before the vertical drive device 4000 works, the cargo airship 100 and the cargo as a whole are subjected to an upward force in the vertical direction, so that the cargo airship 100 can be lifted up. Then, the vertical drive device 4000 is started to apply a vertical downward thrust f to the cargo airship 100 as a whole, so that the force on the cargo airship 100 in the vertical direction is balanced, that is, F=G+f; and the horizontal drive device 3000 can provide a thrust in the horizontal direction to the cargo airship 100 as a whole, so as to realize the transportation of the cargo airship 100; finally, after the cargo airship 100 is transported to the destination, the cargo airship 100 is lowered by increasing the downward thrust f or reducing the net buoyancy F, and finally the cargo can be unloaded.

[0042] In addition, since the net buoyancy F of the cargo airship 100 as a whole during transportation is greater than the sum G of the weight of the cargo airship 100 and the weight of the cargo carried by the cabin 2000, even in extreme situations such as insufficient energy or failure of both the vertical drive device 4000 and the horizontal drive device 3000, the cargo airship 100 will not fall but will float upward; and due to the decrease in the density of the upper atmosphere, the net buoyancy F of the cargo airship 100 will gradually decrease, and under the action of air resistance, the cargo airship 100 will gradually stop moving vertically upward, but will remain stationary at a higher altitude, so that there is more time for flight control, safety control operations, or attempts to restart the vertical drive device 4000 and the horizontal drive device 3000, and more thorough preparations can be made.

[0043] Therefore, this cargo airship 100 can not only ensure the high-altitude transportation function of the cargo airship 100, but also prevent the cargo airship 100 from falling during transportation, thereby improving transportation efficiency and ensuring the safety of ground facilities and personnel.

[0044] The overall capsule 1000 may be made of a skin material having good airtightness, and is very suitable as the overall capsule 1000 for providing a net buoyancy F to the cargo airship 100; the hardness and strength of the skin material are not limited, for example, when the cargo airship 100 does not need to bear excessive loads, an aluminum alloy material may be used; when the cargo airship 100 needs to bear a larger load, a titanium alloy material may be used; the hardness and strength of the skin material shall depend on the actual working conditions and are not specifically limited.

[0045] In addition, there is no limitation on the manner in which the cabin 2000 carries cargo; for example, the cargo (usually cargo that is not too large, such as boxes, etc.) may be completely placed inside the cabin 2000 for transportation; or an opening may be provided on the outer wall of the cabin 2000, and a rope capable of passing through the opening may be provided inside the cabin 2000, and the cargo (usually cargo that is larger in size, such as electric towers, etc.) may be bound by the rope, and finally the cargo is transported by being suspended by the rope outside the cabin 2000; the specific loading method shall depend on the actual working conditions and is not specifically limited.

[0046] like Figure 1 As shown, according to an optional embodiment of the present invention, the overall capsule 1000 includes a first capsule 1100 and a second capsule 1200 connected to the first capsule 1100 , and the first capsule 1100 and the second capsule 1200 are symmetrically arranged relative to the cabin 2000 .

[0047] In this embodiment, the overall capsule 1000 is configured as a first capsule 1100 and a second capsule 1200 that are symmetrical to each other, so that the overall capsule 1000 can obtain a higher lift-to-drag ratio, thereby improving the overall aerodynamic performance of the cargo airship 100, thereby further improving the transportation efficiency of the cargo airship 100.

[0048] It is easy to understand that a first accommodating cavity may be provided in the first capsule body 1100 , and a second accommodating cavity may be provided in the second capsule body 1200 , and the first accommodating cavity and the second accommodating cavity together constitute an accommodating cavity.

[0049] In addition, the specific structures of the first bladder 1100 and the second bladder 1200 may be the same. The first bladder 1100 is taken as an example for further explanation below: for example, the first bladder 1100 may include a main airbag and at least one auxiliary airbag, the first accommodating cavity may be located in the main airbag, and the auxiliary airbag may be used to blow in air from the atmosphere, or discharge air to the atmosphere, so as to adjust the weight G of the cargo airship 100 and the weight of the cargo carried by the cabin 2000, thereby adjusting the height of the cargo airship 100 in the vertical direction. The structure of the second bladder 1200 is the same as that of the first bladder 1100, and will not be repeated here.

[0050] refer to Figure 1 and Figure 2 According to an optional embodiment of the present invention, the vertical driving device 4000 includes a first vertical driving sub-device 4100 and a second vertical driving sub-device 4200, the first vertical driving sub-device 4100 is installed on the outer wall of the first capsule 1100, and the second vertical driving sub-device 4200 is installed on the outer wall of the second capsule 1200.

[0051] In this embodiment, since the first vertical driving sub-device 4100 is arranged corresponding to the first capsule 1100 and the second vertical driving sub-device 4200 is arranged corresponding to the second capsule 1200, the cargo airship 100 as a whole can be subjected to a relatively balanced downward thrust f, thereby facilitating the final force balance of the cargo airship 100.

[0052] It is easy to understand that the first vertical driving sub-device 4100 provides a first thrust f1 as a vertical downward thrust to the cargo airship 100 as a whole, and the second vertical driving sub-device 4200 provides a second thrust f2 as a vertical downward thrust to the cargo airship 100 as a whole, and f1+f2=f is satisfied.

[0053] Continue to refer Figure 1 and Figure 2 Further, according to an optional embodiment of the present invention, the first vertical driving sub-device 4100 and the second vertical driving sub-device 4200 are symmetrically arranged relative to the overall capsule body 1000.

[0054] In this embodiment, the first vertical driving sub-device 4100 and the second vertical driving sub-device 4200 are symmetrically arranged relative to the overall capsule 1000, which can make the downward thrust f of the cargo airship 100 as a whole more balanced, further ensuring that the cargo airship 100 can finally achieve force balance.

[0055] In addition, it is easy to understand that the first vertical driving sub-device 4100 can be disposed at the lower side of the first capsule 1100, and the second vertical driving sub-device 4200 can be disposed at the lower side of the second capsule 1200. Figure 1 and Figure 2 As shown, the cargo airship 100 as a whole is more susceptible to the vertical downward thrust f.

[0056] According to an optional embodiment of the present invention, the first vertical driving sub-device 4100 is a first vector engine, and the second vertical driving sub-device 4200 is a second vector engine.

[0057] In this embodiment, specifically, both the first vector engine and the second vector engine can be aerospace engines. The aerospace engine has the characteristics of high power and the ability to provide more power, and can be applicable to various conditions encountered by the cargo airship 100 during flight.

[0058] like Figure 1 As shown, according to an optional embodiment of the present invention, the horizontal driving device 3000 includes a plurality of horizontal driving sub-devices 3100 , and the plurality of horizontal driving sub-devices 3100 are evenly spaced apart and arranged on the main capsule 1000 .

[0059] In this embodiment, specifically, the horizontal driving sub-device 3100 can use a ducted propeller, and the multiple ducted propellers can adjust the posture and direction of the cargo airship 100 during the launch of the cargo airship 100, ultimately ensuring that the cargo airship 100 can fly to the destination.

[0060] Continue to refer Figure 1 Taking the horizontal driving sub-device 3100 including four ducted propellers as an example, the four ducted propellers are respectively distributed at the left front, right front, left rear and right rear positions of the total capsule 1000; combined with the above-mentioned "the first vertical driving sub-device 4100 can be arranged at the lower side of the first capsule 1100, and the second vertical driving sub-device 4200 can be arranged at the lower side of the second capsule 1200", it can not only avoid the mutual disturbance of the vertical driving device 4000 and the horizontal driving device 3000, but also lower the center of gravity of the cargo airship 100 to increase the attitude stability of the cargo airship 100 during transportation.

[0061] refer to Figure 1 According to an optional embodiment of the present invention, the overall capsule 1000 includes a head and a tail, and the cargo airship 100 also includes a tail wing 5000, which is connected to the outer wall of the tail of the overall capsule 1000, and the tail wing 5000 is used to enhance the stability of the cargo airship 100 as a whole during transportation.

[0062] In this embodiment, it is easy to understand that the arrangement of the tail 5000 can improve the stability of the cargo airship 100 in the pitch, yaw and roll directions as a whole.

[0063] Continue to refer Figure 1 Specifically, the tail 5000 may include four sub-wings 5100 , and the four sub-wings 5100 together constitute an X-shaped tail 5000 .

[0064] According to an optional embodiment of the present invention, the cargo airship 100 further includes: an avionics measurement and control device for recording and adjusting the flight status of the cargo airship 100 and realizing data transmission with the ground; an energy storage battery installed in the cabin 2000, the energy storage battery is used to power the cargo airship 100 as a whole; and a solar panel 6000 installed on the outer wall of the main capsule 1000, the solar panel 6000 is used to charge the energy storage battery.

[0065] In this embodiment, it is easy to understand that the solar panel 6000 can be installed on the top wall of the overall capsule 1000, and the cabin 2000 can be installed on the bottom wall of the overall capsule 1000. Figure 1 As shown;

[0066] In addition, the cabin 2000 may include two parts, one part of the cabin 2000 may be used for carrying cargo, and the other part of the cabin 2000 may be used for accommodating structures of the cargo airship 100 itself, such as avionics measurement and control devices and energy storage batteries;

[0067] Specifically, the avionics measurement and control device may include: a flight parameter sensor, an inertial navigation and positioning system, a flight control computer, and a data transmission system. The flight parameter sensor is used to record the altitude, speed, acceleration, attitude angle, attitude angular velocity, etc. of the cargo airship 100; the inertial navigation and positioning system is used to record the position, heading, altitude, speed, and distance of the cargo airship 100; the flight control computer is used to process the collected flight parameters of the cargo airship 100, and output a control signal to adjust the flight state of the cargo airship 100; the data transmission system is responsible for realizing data transmission between the cargo airship 100 and the ground.

[0068] Figure 3 Flow chart of the airship transportation method provided by the embodiment of the present invention, and reference is made to Figures 1 to 3 The embodiment of the present invention provides an airship transportation method, which is applicable to any of the above-mentioned cargo airships 100, and is characterized in that the airship transportation method includes:

[0069] Step S100: Load cargo into the cabin 2000 of the cargo airship 100, and satisfy the requirement that the net buoyancy F is greater than the sum of the weight of the cargo airship and the weight of the cargo carried by the cabin. After the cargo is loaded, the cargo airship 100 is made to rise.

[0070] Step S200: the cargo airship 100 starts the vertical driving device 4000 in the ascending state, so that the cargo airship 100 as a whole is subjected to a downward thrust f, until F=G+f is satisfied, so that the cargo airship 100 as a whole and the cargo are subjected to a force balance in the vertical direction;

[0071] Step S300: The cargo airship 100 flies to the air above the destination, and the cargo airship 100 descends in the vertical direction to a preset distance from the ground of the destination to unload the cargo.

[0072] In this embodiment, since the net buoyancy F received by the cargo airship 100 as a whole during transportation is greater than the sum G of the weight of the cargo airship 100 and the weight of the cargo carried by the cabin 2000, even in extreme cases such as insufficient energy or failure of both the vertical drive device 4000 and the horizontal drive device 3000, the cargo airship 100 will not fall but will float upward; and due to the decrease in the density of the upper atmosphere, the net buoyancy F of the cargo airship 100 will gradually decrease, and under the action of air resistance, the cargo airship 100 will gradually stop moving vertically upward, but will stay still at a higher altitude, so that there is more time for performing flight control, safety control operations, or attempting to restart the vertical drive device 4000 and the horizontal drive device 3000, and more thorough preparations can be made.

[0073] Therefore, this cargo airship 100 can not only ensure the high-altitude transportation function of the cargo airship 100, but also prevent the cargo airship 100 from falling during transportation, thereby improving transportation efficiency and ensuring the safety of ground facilities and personnel.

[0074] To further understand the scheme, this airship transportation method is described in more detail below.

[0075] Step S100 may specifically include:

[0076] Step S101: fix the cargo airship 100 relative to the ground through the connection device, load the cargo into the cabin 2000 of the cargo airship 100, and satisfy F>G;

[0077] Step S102: releasing the connection between the connecting device and the cargo airship 100, so that the cargo airship 100 ascends;

[0078] The connection device may be a connection rope or the like, which is used to fix the cargo airship 100 to the ground to prevent the cargo airship 100 from continuously being lifted off, thereby facilitating the loading of cargo;

[0079] It is easy to understand that the above-mentioned steps S101 and S102 are only examples of feasible situations; depending on the actual working conditions, the cargo can be loaded first and then the working gas can be filled into the main bag 1000, depending on the specific working conditions. There is no restriction, as long as F>G can be achieved without affecting the loading of cargo.

[0080] Regarding step S200, it should be noted that:

[0081] Because the cargo airship 100 satisfies F>G before the vertical drive device 4000 is started, it means that the direction of the resultant force on the cargo airship 100 in the vertical direction is upward, that is, the cargo airship 100 will continue to rise. Therefore, in order to facilitate the subsequent flight, the vertical drive device 4000 is started to make the cargo airship 100 as a whole receive a downward thrust f, until F=G+f is satisfied, and the cargo airship 100 as a whole and the cargo are subjected to balanced forces in the vertical direction, so as to facilitate the subsequent flight of the cargo airship 100 to the destination.

[0082] Regarding step S300, it should be noted that:

[0083] When the cargo airship 100 descends in the vertical direction to a preset distance from the ground of the destination, the height of the cargo airship 100 is a suitable height for unloading. From the above analysis, it can be seen that due to the different ways in which the cabin 2000 carries cargo, for the way in which cargo (usually cargo that is not too large, such as boxes, etc.) is completely prevented from being transported inside the cabin 2000, the cargo airship 100 needs to be lowered to a very low altitude or even to the ground before unloading is convenient. For the transportation method of binding cargo (usually cargo with larger size, such as electric towers, etc.) with ropes, the cargo airship 100 only needs to be lowered until the cargo is close to or falls to the ground (that is, the cargo airship 100 itself is still a certain distance from the ground). Therefore, for different cargoes and different transportation methods, the height suitable for unloading is different, that is, the preset distance is different, and the specific size of the preset distance needs to be determined according to actual working conditions and is not limited.

[0084] Specifically, according to an optional embodiment of the present invention, step S300 specifically includes:

[0085] Step S301: After the cargo airship 100 flies to the air above the destination, the cargo airship 100 is lowered by increasing the downward thrust f or reducing the net buoyancy F until the cargo airship 100 is vertically at a preset distance from the ground of the destination;

[0086] Step S302: unloading the cargo, and at the same time driving the vertical drive device 4000 to increase the downward thrust f, so that the cargo airship 100 is subjected to balanced force in the vertical direction.

[0087] In this embodiment, similarly, to further understand the solution, step S300 is described in more detail below.

[0088] Regarding step S301, it should be noted that:

[0089] The cargo airship 100 is lowered by increasing the downward thrust f or reducing the net buoyancy F, that is, the cargo airship 100 lands by vertical movement. This landing method has fewer restrictions on the site environment of the destination, thereby increasing the application scenarios of the cargo airship 100.

[0090] Regarding step S302, it should be noted that:

[0091] After the cargo is unloaded, the overall weight of the load-carrying airship is reduced instantly, and when the net buoyancy F and the downward thrust f remain unchanged, the combined upward force on the load-carrying airship in the vertical direction will increase suddenly, which can easily cause the cargo-carrying airship 100 to rise sharply upward; since the air pressure at high altitudes is relatively low, when the cargo-carrying airship 100 rises sharply to high altitudes, the pressure difference between the inside and outside of the accommodating cavity of the total capsule 1000 increases significantly, and the gas will expand rapidly, causing the total capsule 1000 to have the risk of bursting;

[0092] Therefore, in order to prevent the above risks from occurring, it is necessary to drive the vertical drive device 4000 to increase the downward thrust f while unloading the cargo, so that the cargo airship 100 can gradually achieve force balance in the vertical direction, avoiding the cargo airship 100 from rising sharply upward, thereby avoiding the situation where the working gas is greatly increased due to the internal and external pressure difference of the accommodating cavity, which eventually causes the total capsule 1000 to burst; and, since the cargo airship 100 can still be balanced in the vertical direction after unloading the cargo, it is also convenient for the cargo airship 100 to continue to fly.

[0093] In addition, similar to the above-mentioned step S101, before unloading, the cargo airship 100 may be relatively fixed to the ground by a connecting device to further ensure that the cargo airship 100 does not rise continuously, thereby facilitating the unloading of the cargo; similarly, the connecting device may be a connecting rope or the like, which fixes the cargo airship 100 to the ground by the connecting rope to prevent the cargo airship 100 from rising continuously.

[0094] Finally, it should be noted that when the cargo airship 100 needs to adjust its own height, in addition to adjusting the downward thrust f applied by the vertical drive device 4000 to the cargo airship 100 as a whole, it can also be adjusted by adjusting the gas content in the total capsule 1000 to play an auxiliary role in adjusting the height of the cargo airship 100.

[0095] Specifically, a working scenario is used as an example for explanation: when the cargo airship 100 is ready to descend for unloading, if the cargo airship 100 needs to continue flying after unloading, the cargo airship 100 should not completely land on the ground, and it is better to be a certain distance from the ground to facilitate subsequent operations; therefore, it is necessary to finely adjust the height in the vertical direction to ensure that the cargo airship 100 is at a height that is most convenient for unloading. When adjusting the height, if the magnitude of the downward thrust f applied by the vertical drive device 4000 to the cargo airship 100 as a whole is adjusted, when the vertical drive device 4000 is an aerospace engine, it may be inconvenient to finely adjust due to the excessive power of the vertical drive device 4000. At this time, the gas content in the total capsule 1000 can be adjusted to change the sum G of the weight of the cargo airship 100 and the weight of the cargo carried by the cabin 2000, so as to finally facilitate the cargo airship 100 to be at a suitable height for unloading in the vertical direction;

[0096] As for the specific method of changing the sum G of the weight of the cargo airship 100 and the weight of the cargo carried by the cabin 2000, the above-mentioned total capsule 1000 including the first capsule 1100 and the second capsule 1200 is described in detail:

[0097] Taking the first bag 1100 including a main airbag and at least one auxiliary airbag as an example, when the cargo airship 100 needs to descend, the air in the atmosphere can be blown into the auxiliary airbag to increase the overall weight of the cargo airship 100 to assist the descent of the cargo airship 100; when the cargo airship 100 needs to ascend, the air in the atmosphere can be discharged into the auxiliary airbag to reduce the overall weight of the cargo airship 100 to assist the ascent of the cargo airship 100;

[0098] The structure and working method of the second capsule 1200 are completely the same as those of the first capsule 1100, and will not be described again;

[0099] Preferably, the first bladder 1100 and the second bladder 1200 are symmetrically arranged relative to the cabin 2000; and on this basis, in order to further ensure that the cargo airship 100 as a whole can achieve force balance in all directions, when adjusting the gas content in the total bladder 1000, it is necessary to ensure that the gas content in the first bladder 1100 and the second bladder 1200 is always the same; that is, the first bladder 1100 and the second bladder 1200 need to be inflated and exhausted synchronously, and the inflation volume and exhaust volume of the first bladder 1100 and the second bladder 1200 should be kept consistent to maintain the overall force balance of the cargo airship 100, thereby further ensuring the stability of the cargo airship 100 and improving the transportation efficiency to a certain extent.

[0100] 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 thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
