Abstract

Technical Field
[0001] This utility model relates to the field of airship hull technology, specifically a double-layer rigid load-bearing airship hull structure. Background Technology
[0002] With their unique "buoyancy + power" propulsion mode, heavy-duty airships are becoming an important supplement to the modern logistics and transportation system. In practical applications, the advantages of heavy-duty airships are becoming increasingly apparent: they can transport 30-100 tons of ultra-large cargo such as wind power equipment and bridge components in a single trip, at only 1 / 5 the cost of helicopters; by adding modular cargo holds (quick-disassembly container-style design), they can flexibly switch between different types of goods, efficiently transferring everything from disaster relief supplies to engineering equipment. With the integration of "hydrogen power + intelligent navigation" technology, the new generation of heavy-duty airships not only boasts a range exceeding 1000 kilometers but can also avoid strong wind areas through real-time weather data, achieving a better balance between safety and efficiency in heavy-duty transportation.
[0003] In the field of heavy-load airship design, balancing lift performance and safety has always been a core technical challenge. Traditional rigid airships mostly use a single gas filling scheme, which has obvious limitations: if only hydrogen is used as the buoyancy gas, although it can provide strong lift due to its low density, the flammable and explosive nature of hydrogen poses extremely high safety risks in scenarios such as high-altitude static electricity and mechanical friction. Historically, many airship accidents have been caused by hydrogen leaks leading to combustion and explosion, thus limiting the application of this scheme in heavy-load transportation. Utility Model Content
[0004] The purpose of this invention is to provide a double-layer rigid load-bearing airship hull structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-layer rigid load-bearing airship hull structure, comprising: an outer frame, a connecting rod fixedly installed at the bottom of the outer frame, a hull portion provided at the top of the connecting rod, the hull portion including an outer shell, a fixing rod fixedly connected to the inner wall of the outer frame, an inner shell fixedly installed at one end of the fixing rod, and a tail fin portion provided on the right side of the outer frame.
[0006] Preferably, the outer shell is disposed at the top of the connecting rod, an inflatable hopper one is fixedly installed at the bottom of the inner shell, an inflatable hopper two is fixedly installed at the bottom of the outer shell, the outer shell is fixedly installed with the outer frame, the inner shell is disposed inside the outer frame, the inflatable hopper one communicates with the inside of the inner shell, and the inflatable hopper two communicates with the inside of the outer frame.
[0007] Preferably, the tail fin portion includes a tail frame, which is fixedly installed on the right side of the outer frame. A motor is fixedly installed inside the tail frame, and a propeller is fixedly installed at the output end of the motor. Gears and gear plates are provided inside the tail frame.
[0008] Preferably, a mounting plate is fixedly installed at one end of the gear plate, a telescopic rod is fixedly installed on one side of the mounting plate, a bottom shaft is fixedly installed inside the gear, a tail wing is fixedly installed at the top of the bottom shaft, and the tail frame and the tail wing are rotatably mounted together.
[0009] Preferably, the gear is meshed with the gear plate, the mounting plate is movably installed inside the tailstock, the telescopic rod is fixedly installed inside the tailstock, the bottom end of the bottom shaft passes through the tailstock and extends into the tailstock, the bottom shaft is rotatably installed between the tailstock and the tailstock, and the tail fins are respectively located at the top and bottom of the tailstock.
[0010] This invention provides a double-layer rigid load-bearing airship hull structure. It has the following beneficial effects:
[0011] (1) By setting the hull part, hydrogen is evenly filled into each air chamber of the inner shell, and its low density characteristics provide basic buoyancy. Helium, as an inert gas, enhances the overall lift through its own buoyancy. This filling scheme of "high-efficiency lift of inner hydrogen + safety protection of outer helium" further enhances the lift of the airship. At the same time, through the pressure gradient design of the double air layer and independent filling control, a double safety line is built under the premise of ensuring load capacity, which perfectly meets the dual requirements of lift and safety of heavy-load airships.
[0012] (2) By setting a tail wing, the present invention has fixed tail wings on both the left and right sides of the tail frame, and movable tail wings on the top and bottom of the tail frame. When the telescopic rod is activated, the toothed plate moves, driving the gear to rotate. At the same time, the bottom shaft and tail wing rotate, and the heading is adjusted in conjunction with the outer structure, reducing the aerodynamic interference caused by the traditional control surface.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0021] Example 1
[0022] A preferred embodiment of the double-layer rigid load-bearing airship hull structure provided by this utility model is, for example... Figure 1-5 As shown: A double-layer rigid load-bearing airship hull structure includes: an outer frame 1, a connecting rod 2 fixedly installed at the bottom of the outer frame 1, a hull part 3 provided at the top of the connecting rod 2, the hull part 3 including an outer shell 31, a fixing rod 32 fixedly connected to the inner wall of the outer frame 1, an inner shell 33 fixedly installed at one end of the fixing rod 32, and a tail fin part 4 provided on the right side of the outer frame 1;
[0023] The outer shell 31 is set on the top of the connecting rod 2, the bottom of the inner shell 33 is fixedly installed with an inflation bucket 34, the bottom of the outer shell 31 is fixedly installed with an inflation bucket 35, the outer shell 31 is fixedly installed with the outer frame 1, the inner shell 33 is set inside the outer frame 1, the inflation bucket 34 is connected to the inside of the inner shell 33, and the inflation bucket 35 is connected to the inside of the outer frame 1.
[0024] The outer frame 1 is made of aluminum-lithium alloy and combined with a biomimetic honeycomb structure, which reduces the weight of the outer structure. The outer frame 1 is fixedly installed with the outer shell 31 to form the external structure of the airship body. The inner shell 33 is set and fixedly installed with the outer frame 1 through the fixing rod 32, so that the airship body forms a double-layer structure.
[0025] Hydrogen is injected into the inner shell 33 through inflation chamber 1 34, and helium is injected into the outer frame 1 through inflation chamber 2 35. The hydrogen is evenly filled into each air chamber of the inner shell 33, and its low density provides basic buoyancy. Helium, as an inert gas, enhances the overall lift through its own buoyancy. This filling scheme of "efficient lift enhancement with inner hydrogen + safety protection with outer helium" further improves the lift of the airship. At the same time, through the pressure gradient design of the double air layer and independent inflation control, a double safety line is built while ensuring the load capacity, perfectly meeting the dual requirements of lift and safety for heavy-load airships.
[0026] Example 2
[0027] Based on Embodiment 1, a preferred embodiment of the double-layer rigid load-bearing airship hull structure provided by this utility model is, for example... Figure 1-5 As shown: The tail fin part 4 includes a tail frame 41, which is fixedly installed on the right side of the outer frame 1. A motor 42 is fixedly installed inside the tail frame 41, and a propeller 43 is fixedly installed at the output end of the motor 42. A gear 44 and a gear plate 45 are provided inside the tail frame 41. A mounting plate 46 is fixedly installed at one end of the gear plate 45, and a telescopic rod 47 is fixedly installed on one side of the mounting plate 46. A bottom shaft 48 is fixedly installed inside the gear 44, and a tail fin 49 is fixedly installed at the top of the bottom shaft 48. The tail frame 41 and the tail fin 49 are rotatably mounted together. The gear 44 and the gear plate 45 are meshed together. The mounting plate 46 is movably mounted inside the tail frame 41. The telescopic rod 47 is fixedly mounted inside the tail frame 41. The bottom end of the bottom shaft 48 passes through the tail frame 41 and extends into the interior of the tail frame 41. The bottom shaft 48 is rotatably mounted to the tail frame 41. The tail fin 49 is respectively located at the top and bottom of the tail frame 41.
[0028] In the tailstock 41 structure of the double-deck rigid-lift airship, fixed tail fins made of carbon fiber composite material are symmetrically installed on the left and right sides. As a longitudinal stabilizing device during airship flight, it can reduce lateral swaying caused by airflow disturbance. The tailstock is rotatably connected to the bottom shaft 48. The gear 44 fixed at the end of the bottom shaft precisely meshes with the toothed plate 45 at the end of the telescopic rod 47, forming a mechanical transmission link. When the airship needs to adjust its direction of travel, the control system drives the telescopic rod 47 to extend and retract axially, causing the toothed plate 45 to move horizontally. The linear motion of the toothed plate is converted into rotational motion through the gear 44, causing the bottom shaft 48 to rotate synchronously, thereby driving the tail fin 49 to change its orientation.
[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
