Description

Technical Field

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

[0002] Currently, the transportation of goods such as power towers and spare parts in mountainous areas usually adopts the method of building cableways on and under the mountains; however, cableway transportation not only requires a lot of manpower and material resources for construction and maintenance, but also has irreversible impacts on the natural landscape and ecosystem.

[0003] Another way is to transport by airship. Although current airships have the ability to take off and land vertically, vertical take-off and landing when loaded with cargo will consume a lot of energy, seriously affecting the airship's endurance and loading capacity. If the airship is to avoid vertical take-off and landing, the airship needs to take off and land on a runway, which has high requirements for the take-off and landing site and is difficult to meet in harsh areas such as mountainous areas.

[0004] Therefore, how to design an airship transportation method that does not require too high a take-off and landing site while ensuring the airship's endurance and loading capacity 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 design an airship transportation method that can ensure the endurance and loading capacity of the airship without requiring too high a take-off and landing site. This purpose is achieved through the following technical solutions:

[0006] In a first aspect, the present invention provides an airship transportation method, comprising:

[0007] Step S100: lifting the airship from the ground at the starting point to a first preset height, and at the first preset height, the airship achieves force balance in the vertical direction;

[0008] Step S200: The airship lowers the rope to the ground at the starting point at a first preset height, and binds the cargo to the rope;

[0009] Step S300: the airship lifts the cargo by means of a rope bound to the cargo, and the airship falls vertically by a preset distance to a second preset height under the gravity of the cargo, and at the second preset height, the airship and the cargo achieve force balance in the vertical direction;

[0010] Step S400: the airship maintains the second preset altitude and flies to the destination, and then unloads the cargo;

[0011] The second preset height is the distance of the destination from the ground in the vertical direction to the starting point. The first preset height, the second preset height and the preset distance satisfy the following formula: H=h+a; wherein H is the first preset height, h is the second preset height, and a is the preset distance.

[0012] During operation of this airship transportation method, firstly, the cargo and the empty airship are prepared on the ground at the departure point, and then the airship is lifted to a first preset height until the airship achieves force balance in the vertical direction; after the height of the airship is stabilized, the rope is lowered to the ground at the departure point, and then the cargo is tied to the rope to achieve cargo loading of the airship; then, the rope is recovered to lift the cargo, and when the cargo is lifted to the ground away from the departure point, the airship will fall due to the increase in the load of the airship, until it has fallen a preset distance, that is, after the airship has fallen to a second preset height, the airship achieves force balance in the vertical direction again; then the airship maintains level flight until it arrives at the destination, and then the cargo can be unloaded. With this airship transportation method, when the airship is in a cargo-carrying state, the distance it needs to travel in the vertical direction is only a preset distance, and unlike the prior art, the airship does not need to perform a complete vertical take-off and landing process when in a cargo-carrying state, thereby saving a large amount of energy for the airship, thereby ensuring the airship's endurance and loading capacity; and this airship transportation method can be applied to airships that take off and land vertically, and the airship does not need to adopt a sliding bubble take-off and landing method, which greatly reduces the requirements for the take-off and landing site.

[0013] In some embodiments of the present invention, step S300 specifically includes: step S301: the airship lifts the cargo by means of a rope, and at the same time the airbag of the airship discharges part of the air into the atmosphere; step S302: the airship falls a preset distance in the vertical direction under the action of the gravity of the cargo, until the airship is at a second preset height, and the airship and the cargo achieve force balance in the vertical direction.

[0014] In some embodiments of the present invention, step S400 specifically includes: step S401: the airship maintains a second preset altitude and flies level to the destination; step S402: unloading the cargo and retracting the rope.

[0015] In some embodiments of the present invention, after step S400, the airship transportation method further includes: step S500: after unloading the cargo, the airship rises again to the first preset height, and at the first preset height, the airship achieves force balance in the vertical direction; step S600: the airship maintains the first preset height and flies back to the sky above the starting point; repeat steps S200 to S600 until all the cargo is transported to the destination.

[0016] In some embodiments of the present invention, step S500 specifically includes: step S501: after unloading the cargo, the airbag of the airship is blown into part of the air from the atmosphere; step S502: the airship rises again to the first preset height due to the weight reduction, and the airship achieves force balance in the vertical direction.

[0017] In some embodiments of the present invention, step S200 specifically includes: step S201: when the airship is at a first preset height, driving a winch disposed on the airship to lower the rope to the ground at the starting point; step S202: binding the cargo to the rope.

[0018] In a second aspect, the present invention proposes an airship applicable to any of the above-mentioned airship transportation methods, the airship comprising: an airship body; and a lifting device fixedly connected to the airship body, the lifting device having a rope, and the rope can be extended and recovered in a vertical direction.

[0019] In some embodiments of the present invention, the airship includes at least two lifting devices, and any two lifting devices are arranged at intervals on the outer surface of the airship body.

[0020] In some embodiments of the present invention, the lifting device includes: a pod fixedly connected to the outer surface of the airship body, the pod being provided with a through hole; and a winch, the winch including a motor, a gear and a rope, the motor and the gear being both arranged in the pod, the through hole being used for passing the rope, the rope being wound around the gear, and the motor being used for driving the gear to rotate forward and reversely to achieve extension or recovery of the rope.

[0021] In some embodiments of the present invention, the airship body includes: a main airbag, the inner cavity of which contains working gas, and the working gas is used to provide buoyancy for the airship body; and at least one auxiliary airbag, which is used to absorb or discharge air to adjust the buoyancy of the airship body.

[0038] Figure 1 A flow chart of an airship transportation method provided by an embodiment of the present invention; Figure 2 A schematic diagram of a transportation scenario of the airship transportation method provided by an embodiment of the present invention; Figure 1 and Figure 2 , an embodiment of the present invention provides an airship transportation method, comprising:

[0039] Step S100: lifting the airship 100 from the ground A at the starting point to a first preset height H, and at the first preset height H, the airship 100 achieves force balance in the vertical direction;

[0040] Step S200: The airship 100 lowers the rope 2210 to the ground A at the starting point at the first preset height H, and binds the cargo X to the rope 2210;

[0041] Step S300: the airship 100 lifts the cargo X by means of the rope 2210 bound to the cargo, and the airship 100 falls vertically by a preset distance a to a second preset height h under the gravity of the cargo X, and at the second preset height h, the airship 100 and the cargo X achieve force balance in the vertical direction;

[0042] Step S400: the airship 100 maintains the second preset altitude h and flies to the destination B, and then unloads the cargo X;

[0043] The second preset height h is the distance of the destination B in the vertical direction relative to the ground A of the starting point. The first preset height H, the second preset height h and the preset distance a satisfy the following formula: H=h+a;

[0044] Wherein, H is the first preset height, h is the second preset height, and a is the preset distance.

[0045] In this embodiment, the airship transportation method is described in detail step by step as follows:

[0046] For step S100: firstly, prepare the cargo X and the empty airship 100 at the ground A of the starting point, and then lift the airship 100 to a first preset height H until the airship 100 achieves force balance in the vertical direction, that is, the height of the airship 100 is in a stable state;

[0047] For step S200: the rope 2210 is lowered to the ground A at the starting point, and then the cargo X is tied to the rope 2210 to achieve cargo loading of the airship 100;

[0048] Regarding step S300: the rope 2210 is recovered to lift the cargo X. When the cargo X is lifted to the ground A away from the starting point, the airship 100 will fall due to the increase in the load of the airship 100, until it falls a preset distance a, that is, after the airship 100 falls to the second preset height h, the airship 100 realizes force balance in the vertical direction again, that is, the airship 100 is in a stable state again; it should be noted that when the volume of the cargo X is small, in principle, the rope 2210 can be recovered to the inside of the airship, that is, only the cargo X is outside the airship; however, when the volume of the cargo X is large, the recovery of the rope 2210 in this step does not mean that the rope 2210 is completely recovered to the inside of the airship 100, and it is sufficient to meet the requirement that the rope 2210 between the cargo X and the airship 100 during the flight of the airship 100 will not interfere with other hollow objects.

[0049] Regarding step S400: since the second preset height h is the distance of the destination B relative to the ground A of the starting point in the vertical direction, when the airship 100 maintains level flight until it reaches the destination B, the cargo X can be directly unloaded.

[0050] With this airship transportation method, when the airship 100 is in a cargo-carrying state, the distance it needs to travel in the vertical direction is only a preset distance a, and unlike the prior art, the airship 100 does not need to perform a complete vertical take-off and landing process in the cargo-carrying state, thereby saving a large amount of energy of the airship 100; and this airship transportation method can be applied to the airship 100 that takes off and lands vertically, and the airship 100 does not need to adopt a sliding bubble take-off and landing method.

[0051] Therefore, this airship transportation method can ensure the endurance and loading capacity of the airship 100 while not requiring too high requirements on the take-off and landing site.

[0052] It is easy to understand that, under the premise that the second preset height h (i.e., the distance of the destination B in the vertical direction relative to the ground A of the starting point) is determined, the first preset height H depends on the weight and net buoyancy of the airship 100 itself, and the size of the preset distance a depends on the weight of the cargo X; therefore, before transportation, the weight of the airship 100, the weight of the cargo X, and the net buoyancy of the airship 100 need to be confirmed to make the transportation process more efficient;

[0053] In addition, if the weight of the cargo X transported each time is the same and the destination B is also the same, the weight and buoyancy of the airship 100 during successful transportation can be recorded to further improve the efficiency of preparation work for the next transportation.

[0054] According to an optional embodiment of the present invention, step S300 specifically includes:

[0055] Step S301: the airship 100 lifts the cargo X through the rope 2210, and the airbag of the airship 100 discharges part of the air into the atmosphere;

[0056] Step S302: The airship 100 falls a preset distance a in the vertical direction under the gravity of the cargo X until the airship 100 is at a second preset height h, and the airship 100 and the cargo X achieve force balance in the vertical direction.

[0057] In this embodiment, a technical solution for actively adjusting the altitude of the airship 100 is described, and an application scenario is used as an example below:

[0058] For example, after the airship 100 lifts the cargo X to the ground where the cargo X leaves the destination B through the rope 2210, due to the weight of the cargo X not being well controlled or other external factors, the distance of the airship 100 falling in the vertical direction exceeds the preset distance a, that is, the position of the airship 100 in the vertical direction is lower than the second preset height h, part of the air can be discharged through the airbag to reduce the overall weight of the airship 100, until the airship 100 is at the second preset height h, and then the exhaust is stopped to achieve force balance between the airship 100 and the cargo X as a whole in the vertical direction.

[0059] Therefore, this configuration changes the overall weight of the airship 100 by exhausting the airbags into the atmosphere, thereby further ensuring that the airship 100 and the cargo X can achieve force balance in the vertical direction at the second preset height h, thereby improving the efficiency of the airship transportation method.

[0060] In addition, it can be inferred from the previous that the distance that the airship 100 in this embodiment needs to run in the vertical direction when in a cargo-carrying state is only the preset distance a, and in the above-mentioned process of active height adjustment of the airship 100, the height that needs to be adjusted is also limited, that is, the energy consumed by exhausting the airbag will not be too large, and will not affect the endurance and loading capacity of the airship 100.

[0061] According to an optional embodiment of the present invention, step S400 specifically includes:

[0062] Step S401: The airship 100 maintains a second preset altitude h and flies level to the destination B;

[0063] Step S402: Unload cargo X and retract rope 2210.

[0064] In this embodiment, it is easy to understand that if the airship 100 needs to return to the starting point or continue to fly to other places after completing the transportation of the cargo X, in order to ensure the safety of the airship 100 during flight, the rope 2210 needs to be retracted to prevent the rope 2210 from colliding with or entangled with other objects in the air during the flight of the airship 100, thereby causing safety hazards.

[0065] It should be noted that the retracting of the rope 2210 in step S402 can be regarded as completely retracting the rope 2210 into the airship 100 to fully ensure that the rope 2210 is not hung under the airship 100 in the controlled state, thereby further ensuring the safety of the flight of the airship 100.

[0066] As can be seen from the above, the airship 100 can continue to fly after completing a transportation task. Specifically, according to an optional embodiment of the present invention, after step S400, the airship transportation method further includes:

[0067] Step S500: After unloading the cargo X, the airship 100 rises again to the first preset height H, and at the first preset height H, the airship 100 achieves force balance in the vertical direction;

[0068] Step S600: the airship 100 maintains the first preset altitude H and flies back to the sky above the starting point;

[0069] Repeat steps S200 to S600 until all goods X are transported to destination B.

[0070] In this embodiment, this airship transportation method is described in detail step by step:

[0071] For step S500: after unloading the cargo X, the weight of the airship 100 is reduced, and the airship 100 rises again to the first preset height H until the airship 100 achieves force balance in the vertical direction;

[0072] For step S600: if the airship 100 needs to transport cargo X back and forth between the departure point and the destination B, the airship 100 should return to the departure point;

[0073] It is easy to understand that before all the goods X are transported, the airship 100 does not need to land on the ground A at the departure point when returning to the departure point, but should stay above the departure point, and then continuously repeat steps S200 to S600 until all the goods X are transported to the destination B. When the airship 100 returns to the departure point for the last time, it can land on the ground.

[0074] In addition, from the above analysis, it can be seen that if the weight of the cargo X carried by the airship 100 is the same each time during multiple round trips between the same departure point and destination B, the transportation process can be made more efficient.

[0075] According to an optional embodiment of the present invention, step S500 specifically includes:

[0076] Step S501: After unloading the cargo X, the airbag of the airship 100 is partially filled with air from the atmosphere;

[0077] Step S502: The airship 100 rises again to the first preset height H due to the weight reduction, and the airship 100 achieves force balance in the vertical direction.

[0078] In this embodiment, a technical solution for actively adjusting the height of the airship 100 is also recorded, and an application scenario is used as an example to illustrate:

[0079] For example, after the airship 100 is unloaded with cargo X, due to the weight of the cargo X not being well controlled before transportation or other external factors, the distance the airship 100 rises in the vertical direction exceeds the preset distance a, that is, the position of the airship 100 in the vertical direction is higher than the first preset height H, the airbag can be partially blown into air from the atmosphere to increase the overall weight of the airship 100, until the airship 100 is at the first preset height H, and then the blowing is stopped to achieve force balance of the airship 100 in the vertical direction.

[0080] Therefore, this arrangement changes the overall weight of the airship 100 by allowing the airbag to blow part of the air from the atmosphere, thereby further ensuring that the airship 100 can finally achieve force balance in the vertical direction at the first preset height H, thereby improving the efficiency of the airship transportation method; moreover, when the airship 100 returns to the starting point, since the height of the airship 100 is the first preset height H, it is also convenient for the next transportation of the cargo X.

[0081] In addition, in the process of active height adjustment of the airship 100 in this embodiment, the height that needs to be adjusted is also limited, and the airship 100 is in an unloaded state, that is, the energy consumed in the process of blowing part of the air into the airbag from the atmosphere will not be too large, and will not affect the subsequent endurance and loading capacity of the airship 100.

[0082] According to an optional embodiment of the present invention, step S200 specifically includes:

[0083] Step S201: When the airship 100 is at a first preset height H, the winch 2200 disposed on the airship 100 is driven to lower the rope 2210 to the ground A at the starting point;

[0084] Step S202: Bind cargo X to rope 2210.

[0085] In this embodiment, it is easy to understand that since the airship 100 needs to lower the rope 2210 at the first preset height H, a winch 2200 is configured on the airship 100 for ease of operation. The rope 2210 can be lowered and recovered by remotely controlling the winch 2200, which is simple and convenient to operate.

[0086] Figure 3 Schematic diagram of the airship provided in the embodiment of the present invention when carrying cargo, and reference is made to Figures 1 to 3 The embodiment of the present invention further provides an airship 100, which is applicable to any of the above-mentioned airship transportation methods. The airship 100 includes: an airship body 1000; and a lifting device 2000, which is fixedly connected to the airship body 1000. The lifting device 2000 has a rope 2210, and the rope 2210 can be extended and recovered in the vertical direction.

[0087] In this embodiment, the structure and function of the airship 100 are fully described below in combination with the transportation method:

[0088] First, the cargo X and the empty airship 100 are prepared at the ground A of the starting point, and then the airship 100 is lifted to a first preset height H until the airship 100 achieves force balance in the vertical direction, that is, the height of the airship 100 is in a stable state; then, the rope 2210 is lowered to the ground A of the starting point through the lifting device 2000, and the cargo X is tied to the rope 2210 to realize the cargo loading of the airship 100; then, the rope 2210 is recovered to lift the cargo X. When the cargo X is lifted to the ground A away from the starting point, due to the load of the airship 100 The airship 100 will fall until it has fallen a preset distance a, that is, after it has fallen to the second preset height h, the airship 100 will achieve force balance in the vertical direction again, that is, the airship 100 will be in a stable state again; since the second preset height h is the distance of the destination B relative to the ground A of the starting point in the vertical direction, when the airship 100 maintains level flight until it arrives at the destination B, the cargo X is directly unloaded, and finally the rope 2210 is recovered by the lifting device 2000, that is, safety hazards are avoided when the airship 100 continues to fly.

[0089] Therefore, the airship 100 in this embodiment, due to the existence of the lifting device 2000, can realize that the airship 100 lowers the rope 2210 to the ground A at the starting point when the airship 100 is at the first preset height H, which plays a key role in the airship 100 being able to successfully load cargo.

[0090] like Figure 3 As shown, according to an optional embodiment of the present invention, the airship 100 includes at least two lifting devices 2000 , and any two lifting devices 2000 are arranged at intervals on the outer surface of the airship body 1000 .

[0091] In this embodiment, at least two lifting devices 2000 are provided, that is, at least two ropes 2210 are used to bind the cargo X, thereby improving the stability of the connection between the cargo X and the airship body 1000, and further improving the transportation efficiency.

[0092] The number of the lifting devices 2000 is not limited, for example, three or four may be provided; the number of the lifting devices 2000 should be determined according to actual needs without significantly increasing the overall weight of the airship 100 and without causing cumbersome assembly.

[0093] In addition, it is easy to understand that the lifting device 2000 can be installed on the bottom surface of the airship body 1000 to facilitate the retraction and deployment of the rope 2210 and the extraction of the cargo X.

[0094] refer to Figure 3Specifically, according to an optional embodiment of the present invention, the lifting device 2000 includes: a pod 2100, which is fixedly connected to the outer surface of the airship body 1000 and is provided with a through hole; and a winch 2200, the winch 2200 includes a motor, a gear and a rope 2210, the motor and the gear are both arranged in the pod 2100, the through hole is used to pass the rope 2210, the rope 2210 is wound around the gear, and the motor is used to drive the gear to rotate forward and reverse to achieve the extension or recovery of the rope 2210.

[0095] In this embodiment, since the structure and function of the airship 100 have been described above in combination with the transportation method, no further details will be given here. Only the process of retracting and releasing the rope 2210 will be specifically described below:

[0096] Before transportation, the rope 2210 should be tightly wound around the gear, that is, the winch 2200 is entirely located in the nacelle 2100;

[0097] When the rope 2210 needs to be lowered, taking the case where the airship 100 is at the first preset height H and is ready to load cargo as an example, the driving motor controls the gear to rotate forwardly, so that one end of the rope 2210 extends from the through hole of the pod 2100 to the outside of the pod 2100; as the gear continues to rotate forwardly, the rope 2210 will continue to be lowered until the rope 2210 gradually approaches the ground and can be bound with the cargo X, at which time the driving motor can control the gear to stop rotating;

[0098] When it is necessary to recover the rope 2210, it is only necessary to drive the motor to control the gear to rotate in the opposite direction, so that the rope 2210 can be gradually recovered. The specific degree of recovery can depend on the actual working conditions (for example, the airship 100 can be partially recovered when loaded, and the airship 100 can completely recover the rope 2210 into the pod 2100 when unloaded). When the recovered length of the rope 2210 meets the working condition requirements, the motor can be driven to control the gear to stop rotating.

[0099] Specifically, Figure 3 For example, it is easy to understand that Figure 3The cargo X in the figure is a schematic diagram of an electric tower; the electric tower is relatively large in size. When the electric tower is bound to the rope 2210 and the rope 2210 is recovered, in order to ensure the stability between the airship 100 and the electric tower, the rope 2210 cannot be completely recovered into the pod 2100, but it is necessary to keep a certain distance between the upper end of the electric tower and the airship 100 in the vertical direction, that is, when the rope 2210 extending out of the pod 2100 is recovered, a part of it (hereinafter, for the convenience of description, this part of the rope 2210 is referred to as the remaining rope) needs to be left outside the pod 2100. In this way, it is possible to ensure that the electric tower can be transported by the airship 100 and prevent interference between the airship 100 and the electric tower; it should be noted that the length of the remaining rope should not be too long, and it is necessary to ensure that the remaining rope will not interfere with other hollow objects during the flight of the airship 100, which can be determined according to actual working conditions.

[0100] In addition, the motor may be equipped with a trigger device, and the operator may connect the trigger device signal through the controller to realize remote driving of the winch 2200, thereby further improving the convenience of the airship 100 and further improving the efficiency of the transportation of the cargo X.

[0101] Therefore, the arrangement of the pod 2100 and the winch 2200 can ensure the efficiency of the airship 100 in transporting the cargo X, and improves the convenience of operation.

[0102] Continue to refer Figure 3 According to an optional embodiment of the present invention, the airship body 1000 includes: a main airbag 1100, the inner cavity of the main airbag 1100 contains working gas, and the working gas is used to provide buoyancy for the airship body 1000; and at least one auxiliary airbag 1200, the auxiliary airbag 1200 is used to absorb or discharge air to adjust the buoyancy of the airship body 1000.

[0103] The working gas may be helium.

[0104] In this embodiment, similarly, since the structure and function of the airship 100 have been described above in combination with the transportation method, no further details will be given here. The following only takes the above two active adjustment situations as examples to specifically describe the working process of the auxiliary airbag 1200:

[0105] The first case: after the airship 100 lifts the cargo X to the ground where the cargo X leaves the destination B through the rope 2210, due to the weight of the cargo X not being well controlled or other external factors, the distance of the airship 100 falling in the vertical direction exceeds the preset distance a, that is, when the position of the airship 100 in the vertical direction is lower than the second preset height h, part of the air can be discharged through the auxiliary airbag 1200 to reduce the weight of the airship 100 as a whole, until the airship 100 is at the second preset height h, the exhaust is stopped, so that the airship 100 and the cargo X as a whole achieve force balance in the vertical direction;

[0106] Therefore, this arrangement changes the overall weight of the airship 100 by exhausting the auxiliary airbag 1200 into the atmosphere, thereby further ensuring that the airship 100 and the cargo X can achieve force balance in the vertical direction at the second preset height h, thereby improving the efficiency of the airship transportation method;

[0107] In addition, it can be inferred from the previous that the distance that the airship 100 in this embodiment needs to travel in the vertical direction when in a cargo-carrying state is only the preset distance a, and in the above-mentioned process of active height adjustment of the airship 100, the height that needs to be adjusted is also limited, that is, the energy consumed by exhausting the auxiliary airbag 1200 will not be too large, and will not affect the endurance and loading capacity of the airship 100.

[0108] The second situation: after the airship 100 is unloaded with the cargo X, due to the fact that the weight of the cargo X before transportation is not well controlled or other external factors, the distance that the airship 100 rises in the vertical direction exceeds the preset distance a, that is, the position of the airship 100 in the vertical direction is higher than the first preset height H, the auxiliary airbag 1200 may be blown into part of the air from the atmosphere to increase the overall weight of the airship 100, until the airship 100 is at the first preset height H, and then the blowing is stopped to achieve force balance in the vertical direction of the airship 100;

[0109] Therefore, this arrangement changes the weight of the entire airship 100 by allowing the auxiliary airbag 1200 to blow in some air from the atmosphere, thereby further ensuring that the airship 100 can finally achieve force balance in the vertical direction at the first preset height H, thereby improving the efficiency of the airship transportation method; and, when the airship 100 returns to the starting point, since the height of the airship 100 is the first preset height H, it is also convenient for the next transportation of the cargo X;

[0110] In addition, in the process of active height adjustment of the airship 100 in this embodiment, the height that needs to be adjusted is also limited, and the airship 100 is in an unloaded state, that is, the energy consumed in the process of blowing part of the air into the auxiliary airbag 1200 from the atmosphere will not be too large, and will not affect the subsequent endurance and loading capacity of the airship 100.

[0111] Therefore, the arrangement of the airship body 1000 including the main airbag 1100 and the auxiliary airbag 1200 can conveniently adjust the height of the airship 100 without significantly affecting the buoyancy and weight of the airship 100, thereby further improving the transportation efficiency of the airship 100 while ensuring safety.

[0112] It should be noted that the number of auxiliary airbags 1200 is not limited. For example, two auxiliary airbags 1200 can be set. The two auxiliary airbags 1200 are symmetrically arranged relative to the main airbag 1100. When deflated or inflated, the gas content in the two auxiliary airbags 1200 is moderate and consistent, which is more conducive to the overall force balance of the airship 100.

[0113] 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.
