Description

TECHNICAL FIELD

[0001] The present application relates to the field of aircraft technology, in particular to a flying boat and a flying boat transportation method. BACKGROUND

[0002] Currently, in the mountainous area, the goods such as electric towers and parts are transported by setting up a cableway on the mountain and the foot of the mountain. However, the cableway transportation needs a large amount of manpower and material resources for construction and maintenance, and also causes irreversible impact on the natural landscape and ecological system.

[0003] Another way is to transport by a flying boat. Although the current flying boat has the ability of vertical take-off and landing, the vertical take-off and landing under the premise of loading goods will consume a large amount of energy, which seriously affects the endurance and loading capacity of the flying boat. If the flying boat is not required to take off and land vertically, the flying boat needs to take off and land by sliding, which requires a higher landing site, and is difficult to meet in the mountainous area and other harsh areas.

[0004] Therefore, how to design a flying boat transportation method, which does not require a higher landing site, and can guarantee the endurance and loading capacity of the flying boat, has become a technical problem to be solved in the field. SUMMARY

[0005] The purpose of the present application is to at least solve the technical problem of how to design a flying boat transportation method, which does not require a higher landing site, and can guarantee the endurance and loading capacity of the flying boat. The purpose is achieved by the following technical scheme:

[0006] In a first aspect, the present application provides a flying boat transportation method, comprising:

[0007] Step S100: lifting the flying boat from the ground of the starting point to the first preset height, and at the first preset height, the flying boat realizes force balance in the vertical direction;

[0008] Step S200: the flying boat lowers the rope to the ground of the starting point at the first preset height, and binds the goods with the rope;

[0009] Step S300: the flying boat lifts the goods through the rope bound with the goods, and the flying boat falls a preset distance along the vertical direction under the gravity of the goods to the second preset height, and at the second preset height, the flying boat and the goods realize force balance in the vertical direction;

[0010] Step S400: after the flying boat keeps the second preset height and flies to the destination, the goods are unloaded;

[0011] The second preset height is a distance of the destination relative to the ground of the departure point in the vertical direction, and 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] The airship transportation method, in operation, first prepares the goods and the airship without load on the ground of the departure point, then makes the airship ascend to the first preset height until the airship realizes force balance in the vertical direction, then lowers the rope to the ground of the departure point after the height of the airship is stable, then binds the goods with the rope to realize the loading of the airship, then recovers the rope to lift the goods, and when the goods are lifted to be separated from the ground of the departure point, the airship falls due to the increase of the load of the airship until the airship falls to the second preset height, that is, the airship realizes force balance in the vertical direction again, then keeps level flight until the destination is reached, and then unloads the goods.

[0013] In some embodiments of the present application, the step S300 specifically comprises: step S301: the airship lifts the goods through the rope, and the airbag of the airship discharges part of air to the atmosphere; and step S302: the airship falls in the vertical direction by the preset distance under the gravity of the goods until the airship is at the second preset height, and the airship and the goods realize force balance in the vertical direction.

[0014] In some embodiments of the present application, the step S400 specifically comprises: step S401: the airship keeps level flight to the destination at the second preset height; and step S402: unloads the goods and recovers the rope.

[0015] In some embodiments of the present application, after the step S400, the airship transportation method further comprises: step S500: after unloading the goods, the airship ascends to the first preset height again, and at the first preset height, the airship realizes force balance in the vertical direction; and step S600: the airship keeps level flight to the upper space of the departure point at the first preset height; and the steps S200 to S600 are repeated until all the goods are transported to the destination.

[0016] In some embodiments of the present invention, step S500 specifically includes: step S501: after unloading the cargo, the airship's airbags are inflated with some air from the atmosphere; step S502: due to the reduction in weight, the airship rises again to the first preset height, 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 altitude, the winch installed on the airship is driven to lower the rope to the ground at the starting point; step S202: the cargo is tied to the rope.

[0018] Secondly, the present invention proposes an airship applicable to any of the aforementioned airship transportation methods. The airship includes: an airship body; and a lifting device fixedly connected to the airship body. The lifting device has a rope that can extend and be retrieved in a vertical direction.

[0019] In some embodiments of the present invention, the airship includes at least two lifting devices, with any two lifting devices spaced apart 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 having a through hole; and a winch including a motor, gears, and a rope, the motor and gears being disposed in the pod, the through hole for threading the rope through, the rope being wound around the gears, and the motor for driving the gears to rotate forward and backward to achieve the extension or retraction of the rope.

[0021] In some embodiments of the present invention, the airship body includes: a main airbag containing a working gas in its inner cavity, the working gas being used to provide buoyancy to the airship body; and at least one auxiliary airbag for absorbing or expelling air to adjust the buoyancy of the airship body.

[0022] The above description is only an overview of the technical solution of this application.

[0038] Figure 1 A flowchart of an airship transportation method provided in an embodiment of the present invention; Figure 2 This is a schematic diagram of a transportation scenario for the airship transportation method provided in an embodiment of the present invention; see reference. Figure 1 and Figure 2 This invention provides an airship transportation method, comprising:

[0039] Step S100: The airship 100 is lifted 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 from the first preset height H, and binds the cargo X to the rope 2210;

[0041] Step S300: The airship 100 lifts the cargo X via the rope 2210 that is tied to the cargo. Under the gravity of the cargo X, the airship 100 falls vertically a preset distance a to a second preset height h. At the second preset height h, the airship 100 and the cargo X achieve force balance in the vertical direction.

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

[0043] The second preset height h is the vertical distance of destination B 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] Where 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 will be described in detail below:

[0046] For step S100: First, prepare cargo X and empty airship 100 on the ground A at the starting point. Then, let airship 100 take off to the first preset height H until airship 100 achieves force balance in the vertical direction, that is, the height of airship 100 is in a stable state.

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

[0048] For step S300: Rope 2210 is retrieved to lift cargo X. When cargo X is lifted to the ground A above the starting point, the airship 100 will fall due to the increased load. After falling a preset distance a, that is, after the airship 100 falls to the second preset height h, the airship 100 will regain vertical force balance, that is, the airship 100 will return to a stable state. It should be noted that when the volume of cargo X is small, in principle, rope 2210 can be retrieved into the airship, that is, only the cargo X is outside the airship. However, when the volume of cargo X is large, the retrieval of rope 2210 in this step does not mean that rope 2210 is completely retrieved into the airship 100. It is sufficient that the rope 2210 between cargo X and airship 100 will not interfere with other hollow objects during the flight of airship 100.

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

[0050] In this airship transportation method, when the airship 100 is in a cargo-carrying state, the vertical distance it needs to travel is only the preset distance a, without the need for the airship 100 to undergo a complete vertical take-off and landing process in a cargo-carrying state as in the prior art, thus saving a lot of energy for the airship 100; and this airship transportation method can be applied to airships 100 that take off and land vertically, without the need for the airship 100 to use a glide bubble take-off and landing method.

[0051] Therefore, this airship transportation method can ensure the airship 100's endurance and loading capacity without requiring excessively high standards for take-off and landing sites.

[0052] It is easy to understand that, given that the second preset height h (i.e., the vertical distance of destination B 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, while 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 cargo X is the same each time it is transported, and the destination B is also the same, the weight and buoyancy of airship 100 when it is successfully transported can be recorded to further improve the efficiency of preparation work for the next transport.

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

[0055] Step S301: The airship 100 lifts the cargo X via the rope 2210, while the airship 100's airbags expel some air into the atmosphere.

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

[0057] This embodiment describes a technical solution for actively adjusting the altitude of the airship 100. An application scenario is provided below for illustration:

[0058] For example, when the airship 100 lifts cargo X to the ground of destination B via rope 2210, if the weight of cargo X is not properly controlled or other external factors cause the airship 100 to fall more than a preset distance in the vertical direction, that is, when the vertical position of the airship 100 is lower than the second preset height h, some 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, at which point the discharge stops, so that the airship 100 and cargo X are in a state of force balance in the vertical direction.

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

[0060] Furthermore, as previously deduced, the distance that the airship 100 needs to travel in the vertical direction when it is in a cargo-carrying state is only the preset distance a. In the above-mentioned active altitude adjustment process of the airship 100, the altitude that needs to be adjusted is also limited. In other words, the energy consumed by the exhaust of 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: Airship 100 maintains the second preset altitude h and flies horizontally to destination B;

[0063] Step S402: Unload cargo X and retrieve 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 flying to other places after transporting cargo X, in order to ensure the safety of the airship 100 during flight, the rope 2210 needs to be retrieved to avoid the rope 2210 colliding with or getting entangled with other objects in the air during the flight of the airship 100, which would cause safety hazards.

[0065] It should be noted that retracting rope 2210 in step S402 can be regarded as completely retracting rope 2210 into the airship 100, so as to completely ensure that the lower part of the airship 100 will not be suspended by rope 2210 in the controlled state, thereby further ensuring the safety of the airship 100 flight.

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

[0067] Step S500: After unloading 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: Airship 100 maintains the first preset altitude H and flies back to the airspace above the starting point;

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

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

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

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

[0073] It is easy to understand that before all cargo X has been transported, the airship 100 does not need to land on the ground A of the starting point when returning to the starting point. Instead, it should stay in the airspace above the starting point and then repeat steps S200 to S600 until all cargo X has been transported to the destination B. Then, when the airship 100 returns to the starting point for the last time, it can land on the ground.

[0074] Furthermore, as the above analysis shows, if the weight of cargo X carried by airship 100 is the same in each round trip between the same starting 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 cargo X, the airship 100's airbags are inflated with some air from the atmosphere;

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

[0078] This embodiment also describes the technical solution for actively adjusting the altitude of the airship 100. The following example illustrates this using an application scenario:

[0079] For example, after the airship 100 unloads cargo X, if the weight of cargo X was not properly controlled before transportation or other external factors cause the airship 100 to rise a distance greater than a preset distance in the vertical direction, that is, when the airship 100 is higher than the first preset height H in the vertical direction, the airbag can be inflated with some air from the atmosphere to increase the overall weight of the airship 100 until the airship 100 is at the first preset height H, at which point the inflation stops so that the airship 100 can achieve force balance in the vertical direction.

[0080] Therefore, this configuration, by inflating some air into the airbag from the atmosphere to change the overall weight of the airship 100, further ensures that the airship 100 can achieve vertical force balance 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 airship 100 is at the first preset height H, it also facilitates the transportation of the next cargo X.

[0081] In addition, during the active altitude adjustment process of the airship 100 in this embodiment, the altitude that needs to be adjusted is also limited, and the airship 100 is in an unloaded state. That is to say, the energy consumed in the process of inflating part of the airbag from the atmosphere will not be too great and will not affect the airship 100's subsequent endurance and carrying capacity.

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

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

[0084] Step S202: Tie 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 from the first preset height H, a winch 2200 is configured on the airship 100 for ease of operation. The lowering and retrieval of the rope 2210 can be achieved by remotely controlling the winch 2200, which is simple and convenient to operate.

[0086] Figure 3 This is a schematic diagram of an airship carrying cargo according to an embodiment of the present invention, and is also referred to. Figures 1 to 3 The present invention also provides an airship 100, which is applicable to any of the airship transportation methods described above. 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, which can extend and be retrieved in the vertical direction.

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

[0088] First, cargo X and an empty airship 100 are prepared at the starting point, ground A. The airship 100 is then lifted to a first preset height H until it achieves vertical equilibrium, meaning its altitude is stable. Next, the lifting device 2000 lowers the rope 2210 back to ground A, and cargo X is then secured to the rope 2210 to load the airship 100. Then, the rope 2210 is retracted to lift cargo X. When cargo X is lifted off ground A, due to the load on the airship 100… As the altitude increases, the airship 100 will descend until it reaches a preset distance 'a', which is the second preset height 'h'. At this point, the airship 100 will regain vertical equilibrium, meaning it will be in a stable state again. Since the second preset height 'h' is the vertical distance of destination B relative to the ground A at the starting point, once the airship 100 maintains level flight and arrives at destination B, the cargo X will be unloaded directly. Finally, the rope 2210 will be retrieved via the lifting device 2000, thus avoiding any safety hazards during the continued flight of the airship 100.

[0089] Therefore, in this embodiment, the airship 100, due to the presence of the lifting device 2000, can lower 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's successful cargo loading.

[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 spaced apart on the outer surface of the airship body 1000.

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

[0092] The number of lifting devices 2000 is not limited; for example, three or four can be set. The number of lifting devices 2000 should be determined according to actual needs, provided that the overall weight of the airship 100 is not significantly increased and the assembly is not complicated.

[0093] Additionally, it is easy to understand that the lifting device 2000 can be mounted on the bottom surface of the airship body 1000 to facilitate the deployment and retrieval of the rope 2210 and the retrieval of cargo X.

[0094] refer to Figure 3Specifically, according to an optional embodiment of the present invention, the lifting device 2000 includes: a pod 2100 fixedly connected to the outer surface of the airship body 1000, the pod 2100 having a through hole; and a winch 2200, the winch 2200 including a motor, a gear, and a rope 2210, the motor and the gear being disposed in the pod 2100, the through hole for threading the rope 2210 through, the rope 2210 being wound around the gear, and the motor for driving the gear to rotate forward and in reverse to achieve the extension or retraction of the rope 2210.

[0095] In this embodiment, since the structure and function of the airship 100 have already been described in conjunction with the transportation method, they will not be repeated here. The following is a detailed description of the launching and retracting process of the rope 2210:

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

[0097] When it is necessary to lower the rope 2210, taking the airship 100 at the first preset height H ready to carry cargo as an example, the drive motor controls the gear to rotate in the forward direction so that one end of the rope 2210 extends out of the gondola 2100 through the through hole; as the gear continues to rotate in the forward direction, the rope 2210 will continue to be lowered until the rope 2210 gradually approaches the ground and can be tied to the cargo X. At this time, the drive motor can control the gear to stop rotating.

[0098] When it is necessary to retrieve rope 2210, simply drive the motor to control the gear to rotate in the opposite direction, and the rope 2210 will be gradually retrieved. The specific degree of retrieval depends on the actual working conditions (for example, the airship 100 can be partially retrieved when it is loaded, and the airship 100 can completely retrieve the rope 2210 into the gondola 2100 when it is unloaded). When the length of the retrieved rope 2210 meets the working requirements, the motor can be driven to control the gear to stop rotating.

[0099] Specifically, with Figure 3 For example, it is easy to understand that, Figure 3Cargo X in the diagram represents a power tower. The power tower is relatively large. When the power tower is tied to rope 2210, to ensure stability between the airship 100 and the power tower during rope 2210 retrieval, the rope 2210 cannot be completely retrieved into the gondola 2100. Instead, the top of the power tower needs to maintain a certain vertical distance from the airship 100. That is, a portion of the rope 2210 extending outside the gondola 2100 (hereinafter referred to as the "remaining rope") must remain outside the gondola 2100 during retrieval. This ensures that the power tower can be transported by the airship 100 while preventing interference between the airship 100 and the power tower. It should be noted that the length of the remaining rope should not be too long, ensuring that the remaining rope will not interfere with other hollow objects during the airship 100's flight. The specific length can be determined based on actual operational requirements.

[0100] In addition, the motor can be equipped with a triggering device, and the operator can remotely drive the winch 2200 by connecting the controller to the triggering device signal, thereby further improving the convenience of the airship 100's operation and thus improving the efficiency of cargo X transportation.

[0101] Therefore, the configuration of the pod 2100 and the winch 2200 ensures the efficiency of the airship 100 in transporting cargo X, and improves the ease of operation.

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

[0103] The working gas can be helium.

[0104] In this embodiment, similarly, since the structure and function of this airship 100 have already been described in conjunction with the transportation method, they will not be repeated here. The following will only use the two active adjustment scenarios mentioned above as examples to specifically explain the working process of the auxiliary airbag 1200:

[0105] In the first scenario: after the airship 100 lifts cargo X to the ground of destination B via rope 2210, if the weight of cargo X is not properly controlled or other external factors cause the airship 100 to fall more than a preset distance in the vertical direction, i.e., the airship 100 is lower than the second preset height h in the vertical direction, some air can be discharged through the auxiliary airbag 1200 to reduce the overall weight of the airship 100 until the airship 100 is at the second preset height h, at which point the discharge stops, so that the airship 100 and cargo X are in a vertical force balance.

[0106] Therefore, this configuration changes the overall weight of the airship 100 by expelling exhaust gas from the auxiliary airbag 1200 to the atmosphere, thereby further ensuring that the airship 100 and the cargo X can achieve a vertical force balance at the second preset height h, thus improving the efficiency of the airship transportation method.

[0107] Furthermore, as previously deduced, the distance that the airship 100 needs to travel in the vertical direction when it is in a cargo-carrying state is only the preset distance a. In the above-mentioned active altitude adjustment process of the airship 100, the altitude that needs to be adjusted is also limited. In other words, the energy consumed by the exhaust of 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 scenario: After the airship 100 unloads cargo X, if the weight of cargo X was not properly controlled before transportation or other external factors cause the airship 100 to rise a distance greater than the preset distance a in the vertical direction, that is, when the airship 100 is higher than the first preset height H in the vertical direction, the auxiliary airbag 1200 can be inflated with some air from the atmosphere to increase the overall weight of the airship 100 until the airship 100 is at the first preset height H, at which point the inflation stops so that the airship 100 can achieve force balance in the vertical direction.

[0109] Therefore, this configuration, by inflating some air from the atmosphere into the auxiliary gasbag 1200 to change the overall weight of the airship 100, further ensures that the airship 100 can achieve vertical force balance at the first preset altitude H, thereby improving the efficiency of the airship transportation method; moreover, when the airship 100 returns to the starting point, since the airship 100 is at the first preset altitude H, it also facilitates the transportation of the next cargo X.

[0110] In addition, during the active altitude adjustment process of the airship 100 in this embodiment, the altitude that needs to be adjusted is also limited, and the airship 100 is in an unloaded state. That is to say, the energy consumed in the process of inflating part of the airbag 1200 from the atmosphere will not be too large and will not affect the airship 100's subsequent endurance and loading capacity.

[0111] Therefore, the arrangement of the airship body 1000 including the main airbag 1100 and the auxiliary airbag 1200 can easily adjust the altitude of the airship 100 without significantly affecting its buoyancy and weight, thereby further improving the transport 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 up. The two auxiliary airbags 1200 are symmetrically arranged with respect to the main airbag 1100. When exhausting or inflating, 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 description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
