Description

Technical Field

[0001] This application relates to an unmanned airship, specifically a drone-towed heavy-duty unmanned airship. Background Technology

[0002] An airship is a lighter-than-air aircraft. Its biggest difference from a hot air balloon lies in its propulsion and flight control systems. An airship consists of a large, streamlined hull, a gondola located beneath the hull, a tail section for stabilization and control, and a propulsion system. The hull's gasbag is filled with a less dense gas (such as hydrogen or helium) to generate buoyancy and lift the airship. The gondola carries passengers and cargo, while the tail section controls and maintains heading and pitch stability. Large civilian airships can also be used for transportation, entertainment, disaster relief, film and television production, and scientific experiments. Structurally, airships can be divided into three categories: flexible airships, rigid airships, and semi-rigid airships. The shape of the gasbag in a flexible airship... It is maintained by the pressure of the buoyant gas filled into the main gasbag, hence this type of airship is also called a pressure airship. Rigid airships have a complete metal structure, and the metal structure maintains the shape of the main gasbag. The buoyant gas rushes into dozens or more independent small gasbags within the frame to generate the lift required by the airship. Semi-rigid airships are basically pressure airships. Although they use metal or carbon fiber keels as the supporting frame, the shape of their gasbags still needs to be maintained by the pressure of the buoyant gas. In terms of the type of gas filling, airships are divided into: hydrogen airships, helium airships, and thermodynamic airships. Early airships were all hydrogen airships. Because hydrogen is flammable and explosive, modern airships are mostly helium airships. Unmanned airships are airships that are not piloted.

[0003] Currently, the tow ropes of unmanned airships are difficult to adjust in length according to usage requirements. If the tow rope is too long, it will swing freely during flight, affecting the flight mission. If the tow rope is too short, it will affect the towing of the unmanned airship and make it difficult to ensure the safe landing of the airship, thus affecting the use of the unmanned airship. At the same time, existing unmanned airships are prone to movement when loading and unloading cargo, which is inconvenient. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention designs a drone-towed heavy-duty unmanned airship. The towing structure allows for the retraction and extension of the drone's tow rope, solving the problem of difficulty in adjusting the tow rope's length. Furthermore, a guide component ensures the tow rope is evenly wound onto the reel, preventing tangled entanglement and facilitating flight and towing. The landing structure enhances stability during docking, overcoming the difficulties and imbalance associated with single-wheel landing gear. The load-bearing structure allows for the loading of cargo and improves stability during loading and unloading, preventing movement and facilitating cargo loading.

[0032] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0033] Reference Figures 1 to 2 A drone-towed heavy-duty unmanned airship includes a towing structure. The towing structure includes an unmanned airship airbag assembly 1, a support column 2, a support plate 3, a first fixed plate 4, a winding motor 5, a winding shaft 6, a second fixed plate 7, and a drone towing rope 8. The support column 2 is fixedly connected to the bottom of the unmanned airship airbag assembly 1. The support plate 3 is fixedly connected to the bottom end of the support column 2. The first fixed plate 4 is fixedly connected to the top of the support plate 3. The winding motor 5 is fixedly connected to one side of the first fixed plate 4. The winding shaft 6 is fixedly connected to the output end of the winding motor 5. One end of the winding shaft 6 is rotatably connected to the second fixed plate 7. The second fixed plate 7 is fixedly connected to the top of the support plate 3. The drone towing rope 8 is connected and fixedly connected to the winding shaft 6. A guide assembly is provided on one side of the winding shaft 6.

[0034] Through the above technical solution, the towing structure can be used to reel in and unleash the drone tow rope 8, and the guide component can be used to ensure that the drone tow rope 8 is evenly wound on the take-up shaft 6, preventing the drone tow rope 8 from becoming tangled and difficult to reel in and unleash, thus facilitating the flight and towing of the unmanned airship. In use, the take-up motor 5 can drive the take-up shaft 6 to rotate, and the rotation of the take-up shaft 6 can reel in and unleash the drone tow rope 8, thereby adjusting the length of the drone tow rope 8, facilitating the towing of the unmanned airship, and also facilitating the docking and use of the unmanned airship. Furthermore, when the drone tow rope 8 is being reeled in and unleashed, the guide component can guide the drone tow rope 8, ensuring that the drone tow rope 8 is evenly wound on the take-up shaft 6, preventing the drone tow rope 8 from becoming tangled and affecting the reeling in and unleashing.

[0035] Specifically, such as Figure 2 As shown, the bottom of the unmanned airship airbag assembly 1 is fixed with several support columns 2, and the top of the support plate 3 is fixed with two first fixing plates 4 that are symmetrically distributed on the left and right. One end of the drone towing rope 8 is connected to the surface of the winding shaft 6, and the other end of the drone towing rope 8 is provided with a drone towing end.

[0036] As a further optimization scheme, such as Figures 3 to 7 As shown, the guiding assembly includes a guide housing 9, a guide motor 10, a first sprocket 11, a transmission chain 12, a second sprocket 13, a first rotating column 14, a first threaded column 15, a first moving plate 16, a connecting plate 17, a second moving plate 18, a mounting bracket 19, a guide ring 20, and a rotating sleeve 21. The guide housing 9 is fixed to the top of the support plate 3. The guide motor 10 is fixed to the inner wall of the guide housing 9. The output end of the guide motor 10 is fixed to the first sprocket 11, and the surfaces of the first sprocket 11 are engaged. A connecting transmission chain 12 is engaged with the surface of a second sprocket 13. A first rotating post 14 is fixedly connected to one side of the second sprocket 13, and one end of the first rotating post 14 is rotatably connected to the inner wall of the guide housing 9. A first threaded post 15 is fixedly connected to one side of both the second sprocket 13 and the first sprocket 11. A first moving plate 16 is threadedly connected to the surface of the first threaded post 15. A connecting plate 17 is fixedly connected to one side of the first moving plate 16, and a second moving plate 18 is fixedly connected to one end of the connecting plate 17. A mounting bracket 19 is fixedly connected to one side of the movable plate 18, and a guide ring 20 is fixedly connected to one side of the mounting bracket 19. A rotating sleeve 21 is rotatably connected to the surface of the guide ring 20. When the drone tow rope 8 is retracted or extended, the guide motor 10 drives the first sprocket 11 to rotate, thereby driving the transmission chain 12 to rotate, and then driving the second sprocket 13 to rotate. When the first sprocket 11 and the second sprocket 13 rotate, they can drive the first threaded post 15 to rotate. At this time, the first rotating post 14 can support the second sprocket 13, so that the second sprocket 15... 3. It is more stable when rotating. When the first threaded column 15 rotates, it can drive the first moving plate 16 to move, thereby driving the connecting plate 17 to move in the same direction. When the connecting plate 17 moves, it can drive the second moving plate 18 to move in the same direction, thereby driving the mounting bracket 19 to move in the same direction, and then driving the guide ring 20 and the rotating sleeve 21 to move in the same direction. At this time, since the drone towing rope 8 is inside the guide ring 20, the guide ring 20 can pull the drone towing rope 8, so that the drone towing rope 8 can be easily and evenly wound on the winding shaft 6.

[0037] Specifically, such as Figures 3 to 7As shown, the top of the support plate 3 is fixed with two symmetrically distributed guide housings 9. The guide housings 9 have connection ports on their sides. The top and both sides of the first moving plate 16 are fixed with connecting plates 17. One side of the connecting plate 17 passes through the connection port and extends to the outside of the guide housing 9. The guide ring 20 has a rectangular ring structure. The upper and lower parts of the guide ring 20 are fixed with mounting brackets 19. The cross-section of the mounting brackets 19 has a U-shaped structure. One end of the first threaded post 15 is rotatably connected to the inner cavity side wall of the guide housing 9.

[0038] As an optimization solution, such as Figure 2 and Figure 8 As shown, the device includes a lifting structure, which comprises an inclined support rod 22, a first sliding wheel assembly 23, a first fixing ring 24, an auxiliary rod 25, a first fixing frame 26, a reinforcing crossbar 27, a second fixing frame 28, and a second fixing ring 29. The inclined support rod 22 is fixed to the bottom of the support plate 3, and the first sliding wheel assembly 23 is fixed to the bottom of the inclined support rod 22. The first fixing ring 24 is fixed to the surface of the inclined support rod 22. An auxiliary rod 25 is provided on one side of the first fixing ring 24. The first fixing frame 26 is rotatably connected to both ends of the auxiliary rod 25. The first fixing frame 26 located on the upper side is fixed to the bottom of the support plate 3, and the first fixing frame 26 located on the lower side is fixed to one side of the first fixing ring 24. A reinforcing crossbar 27 is provided on one side of the inclined support rod 22. The second fixing frame 28 is fixed to both ends of the reinforcing crossbar 27, and the two second fixing frames 28 are respectively fixed to one side of the second fixing ring 29. The second fixing ring 29 is fixed to the surface of the inclined support rod 22.

[0039] Through the above technical solution, the landing structure can make the unmanned airship more stable when docking and more stable when stationary, which facilitates the docking of the unmanned airship. In use, the first fixed frame 26 and the reinforcing crossbar 27 can make the support of the inclined support rods 22 on both sides more stable, thus making the unmanned airship more stable when docking and more balanced when docking, which facilitates the take-off and landing of the unmanned airship. Furthermore, the first sliding wheel group 23 can facilitate the movement of the unmanned airship.

[0040] Specifically, such as Figure 8 As shown, the inclined support rod 22 and the auxiliary rod 25 are both inclined. The first fixed frame 26 and the second fixed frame 28 are both composed of a central column and a side plate. The two ends of the central column are fixedly connected to the side plates. The surface of the central column is rotatably connected to the auxiliary rod 25 or the reinforcing crossbar 27 respectively.

[0041] As an optimization solution, such as Figure 2As shown, the structure includes a load-bearing structure, which comprises a load-bearing housing 30, a second sliding wheel assembly 31, a partition plate 32, a limiting post 33, a sliding plate 34, a second threaded post 35, and an anti-slip post 36. The load-bearing housing 30 is fixed to the bottom of the support plate 3. The second sliding wheel assembly 31 is fixed to the bottom of the load-bearing housing 30. The partition plate 32 is fixed to the bottom of the inner cavity of the load-bearing housing 30. The limiting post 33 is fixed to the bottom of the inner cavity of the load-bearing housing 30. The sliding plate 34 is slidably connected to the surface of the limiting post 33. The sliding plate 34 is threadedly connected to the surface of the second threaded post 35. One end of the second threaded post 35 is connected to the drive assembly. The anti-slip post 36 is fixed to the bottom of the sliding plate 34.

[0042] Through the above technical solution, the load-bearing structure can be used to load goods, and can make the unmanned airship more stable when loading and unloading goods, which facilitates loading and unloading of goods. In use, the drive component can drive the second threaded column 35 to rotate. When the second threaded column 35 rotates, it can drive the sliding plate 34 to move down along the limiting column 33, thereby driving the anti-slip column 36 to move in the same direction, so that the bottom of the anti-slip column 36 is in close contact with the ground, preventing the unmanned airship from moving when loading and unloading goods, which facilitates loading and unloading of goods. When it is necessary to move the unmanned airship, the anti-slip column 36 is moved away from the ground in the opposite way, and then the second sliding wheel group 31 and the first sliding wheel group 23 can be used to move the unmanned airship.

[0043] As a further optimization scheme, such as Figure 2 and Figure 9 As shown, the drive motor includes an anti-slip motor 37, a central sprocket 38, a side chain 39, a side sprocket 40, and a second rotating column 41. The anti-slip motor 37 is fixed to the top of the inner cavity of the load-bearing housing 30. The output end of the anti-slip motor 37 is fixed to the central sprocket 38. The side of the central sprocket 38 is engaged with the side chain 39. The side chain 39 is engaged with the side of the side sprocket 40. The top of the side sprocket 40 is fixed to the second rotating column 41, which is fixed to the top of the inner cavity of the load-bearing housing 30. The bottom of the side sprocket 40 is fixed to a second threaded column 35. In use, the anti-slip motor 37 drives the central sprocket 38 to rotate, thereby driving the side chain 39 to rotate, and then driving the side sprocket 40 to rotate. At this time, the second rotating column 41 can make the rotation of the side sprocket 40 more stable. When the side sprocket 40 rotates, it can drive the second threaded column 35 to rotate, thereby providing driving force for the rotation of the second threaded column 35.

[0044] Specifically, such as Figure 2 and Figure 9As shown, the central sprocket 38 consists of an upper sprocket and a lower sprocket, and the lower sprocket is fixedly connected to the bottom of the upper sprocket. Side chains 39 are meshed with the sides of both the upper and lower sprockets, and side sprockets 40 are meshed with the two side chains 39 in opposite directions. The bottom of each side sprocket 40 is fixedly connected with a second threaded post 35, and the bottom end of the second threaded post 35 is rotatably connected to the bottom of the inner cavity of the load-bearing housing 30.

[0045] Specifically, such as Figure 2 and Figure 10 As shown, a limiting post 33 is provided between the load-bearing housing 30 and the partition plate 32. Four limiting posts 33 with a rectangular structure are fixed to the bottom of the inner cavity of the load-bearing housing 30. The sliding plate 34 has two symmetrically distributed limiting holes. The top of the limiting post 33 passes through the limiting hole and is fixed to the top of the inner cavity of the load-bearing housing 30. The limiting post 33 can limit the movement trajectory of the sliding plate 34. Two symmetrically distributed anti-slip posts 36 are fixed to the bottom of the sliding plate 34. Four anti-slip openings with a rectangular structure are provided on the bottom surface of the load-bearing housing 30. The anti-slip posts 36 can be moved out of the load-bearing housing 30 through the anti-slip openings. A second sliding wheel set 31 is fixed to each of the four corners of the bottom of the load-bearing housing 30.
