Technical Field
[0001] This utility model relates to the field of composite material underwater vehicles, and in particular to a composite material underwater vehicle hull. Background Technology
[0002] Composite materials are widely used in the manufacture of underwater vehicles. These materials possess numerous advantages, such as high strength, low density, and good corrosion resistance, making them an ideal choice for important components like the hull, frame, and propulsion system of underwater vehicles.
[0003] The application of composite materials can significantly improve the pressure resistance of underwater vehicle hulls, which is particularly important for deep-sea equipment. For example, a lightweight, high-rigidity composite pressure hull structure is designed to overcome the shortcomings of traditional metal pressure hulls. By incorporating composite material reinforcing ribs, it enhances instability load capacity, suppresses crack propagation, and achieves weight reduction and efficiency improvement. Furthermore, composite materials can be used to manufacture components with specific functions, such as high-damping, lightweight sandwich composite rudders for underwater vehicles, which effectively dampen vibrations, reduce weight, and improve overall performance.
[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Most of the connection structures currently used require opening holes or slots on the surface of the housing and fixing with screws or wedge rings. However, the disadvantage of fixing with screws or wedge rings is that opening holes or slots damages the overall structure of the housing and reduces the structural strength. Utility Model Content
[0005] To improve the current connection structure, most of them require opening holes or slots on the shell surface and fixing with screws or wedge rings. However, the disadvantage of fixing with screws or wedge rings is that opening holes or slots damages the overall structure of the shell and reduces the structural strength. This application provides a composite material underwater vehicle shell.
[0006] This application provides a composite material underwater vehicle hull with the following technical solution: A composite material underwater vehicle hull includes a vehicle hull, the surface of which is provided with a connecting assembly and a disassembly assembly.

A threaded ring is fixed to the surface of the connecting block, a sealing gasket is fitted on the surface of the threaded ring, and a sealing cover is threadedly connected to the surface of the threaded ring. A connecting cylinder is fixed to the top surface of the connecting block, and an L-groove is formed on the surface of the connecting cylinder. A limiting groove is formed on the inner wall of the L-groove. A spring is provided inside the connecting cylinder, and a protruding post is movably connected inside the connecting cylinder. A limiting post is fixed to the surface of the protruding post.
[0007] Furthermore, the slot is provided with a retaining ring inside, and a connecting shell is fixed to the surface of the retaining ring.
[0008] Furthermore, the protruding post passes through the aircraft housing and the retaining ring in sequence, and extends into the interior of the retaining ring; the threaded ring and the connecting block are an integrated structure.
[0009] Furthermore, the surface of the limiting post contacts the inner wall of the L-groove and the limiting groove, and the connecting block and the vehicle shell are an integrated structure.

A sleeve is fixed to the surface of the wing support, a groove is opened on the surface of the sleeve, and a spring is provided inside the sleeve. A protruding post is movably connected inside the sleeve, and a connecting post is fixed to the surface of the protruding post.
[0011] Furthermore, the surface of the glider body is fitted to the inner wall of the wing support, and the second protrusion passes through the wing support and the glider body in sequence, extending into the interior of the glider body.
[0012] Compared with related technologies, the composite material underwater vehicle hull provided by this utility model has the following beneficial effects:
[0013] This utility model provides a composite material underwater vehicle hull. By providing a connecting assembly on the surface of the hull, and having a retaining ring, a connecting cylinder, and a sealing cover inside the connecting assembly, when the user slides a protruding post, the protruding post moves, causing it to separate from the retaining ring. Simultaneously, sliding the retaining ring and the connecting cover allows for disassembly. Since the side surface of the hull has a groove with a retaining ring inside, the connecting assembly can connect the connecting cover to the hull without needing to open holes or grooves, thus improving the overall structure of the hull and increasing its strength.

[0020] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings show typical embodiments of this utility model.
[0021] Example 1:
[0022] like Figure 1-4 As shown, the present invention discloses a composite material underwater vehicle hull, comprising a vehicle hull 1, a connecting assembly 2 and a disassembly assembly 3 on the surface of the vehicle hull 1, the connecting assembly 2 including a slot 201 formed on the surface of the vehicle hull 1, and a connecting block 202 fixed to the surface of the vehicle hull 1, the surface of the connecting block 202 being fixed with a threaded ring 203, the surface of the threaded ring 203 being fitted with a sealing gasket 204, and the surface of the threaded ring 203 being threadedly connected with a sealing cover 205, the top surface of the connecting block 202 being fixed with a connecting cylinder 206, the surface of the connecting cylinder 206 being formed with an L-groove 207, the inner wall of the L-groove 207 being formed with a limiting groove 208, the interior of the connecting cylinder 206 being provided with a spring 209, the interior of the connecting cylinder 206 being movably connected with a protrusion 210, and the surface of the protrusion 210 being fixed with a limiting post 211.
[0023] like Figure 1-4 As shown, the slot 201 has a retaining ring 212 inside, and a connecting shell 213 is fixed on the surface of the retaining ring 212.
[0024] like Figure 1-4 As shown, the protruding post 210 passes through the aircraft hull 1 and the retaining ring 212 in sequence and extends into the interior of the retaining ring 212. The threaded ring 203 and the connecting block 202 are an integrated structure.
[0025] like Figure 1-4As shown, the surface of the limiting post 211 is in contact with the inner wall of the L groove 207 and the limiting groove 208, and the connecting block 202 is an integral structure with the aircraft shell 1.
[0026] In practice, a slot 201 is provided on the side surface of the aircraft hull 1, and a retaining ring 212 is provided inside the slot 201. Using the connecting cylinder 206 and other parts inside the connecting assembly 2, the connecting shell 213 can be connected to the aircraft hull 1 without opening holes or slots, thus improving the overall structure of the aircraft hull 1 and increasing its strength. The sealing gasket 204, sealing cover 205 and threaded ring 203 are provided to seal the connecting cylinder 206, improving its waterproof performance. When it is necessary to disassemble the connecting shell 213, the sealing cover 205 is rotated to disassemble it first. At the same time, the sliding limit post 211 is slid, which drives the protrusion 210 to slide. Simultaneously, the limit post 211 is rotated, and under the action of the spring 209, the limit post 211 is engaged with the limit groove 208, and the sliding connecting shell 213 can be disassembled.
[0027] Example 2:
[0028] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: the disassembly assembly 3 includes a wing support 301 fixed to the surface of the aircraft shell 1, and the wing support 301 has a glider body 302 inside, a sleeve 303 fixed to the surface of the wing support 301, a sliding groove 304 opened on the surface of the sleeve 303, and a second spring 305 inside the sleeve 303, and a second protrusion 306 movably connected inside the sleeve 303, and a connecting post 307 fixed to the surface of the second protrusion 306.
[0029] like Figure 1-4 As shown, the surface of the glider body 302 is attached to the inner wall of the wing support 301, and the second protrusion 306 passes through the wing support 301 and the glider body 302 in sequence, and extends into the interior of the glider body 302.
[0030] During implementation, when it is necessary to disassemble the glider body 302, the connecting column 307 can be slid to drive the second protrusion 306 to slide, thereby separating the second protrusion 306 from the glider body 302. By sliding the glider body 302, the glider body 302 can be separated from the wing support 301. Similarly, the glider body 302 can be installed.
[0031] The advantages of this technical solution in practical applications include, but are not limited to, the following:
[0032] 1. The connecting assembly 2 is equipped with a retaining ring 212, a connecting cylinder 206, and a sealing cover 205. When the user slides the protrusion 210, the protrusion 210 moves, thereby separating the protrusion 210 from the retaining ring 212. Simultaneously, by sliding the retaining ring 212 and the connecting shell 213, it can be disassembled. Since the side surface of the aircraft housing 1 is provided with a groove 201, and the groove 201 is provided with a retaining ring 212, the connecting assembly 2 can be used to connect the connecting shell 213 to the aircraft housing 1. This eliminates the need for opening holes or slots, thus avoiding damage to the overall structure of the aircraft housing 1 and improving its strength.
[0033] 2. The disassembly assembly 3 is equipped with a wing support 301 and a sleeve 303. When the user slides the second protrusion 306, the second protrusion 306 moves, thereby separating the second protrusion 306 from the glider body 302. By sliding the glider body 302, the glider body 302 can be separated from the wing support 301, which is convenient for disassembly.
[0034] In this technical solution, a slot 201 is provided on the side surface of the aircraft hull 1, and a retaining ring 212 is provided inside the slot 201. Using the connecting cylinder 206 and other parts inside the connecting assembly 2, the connecting shell 213 can be connected to the aircraft hull 1 without opening holes or slots, thus avoiding damage to the overall structure of the aircraft hull 1 and improving strength. Through the setting of the sealing gasket 204, the sealing cover 205 and the threaded ring 203, the sealing cover 205 seals the connecting cylinder 206, improving its waterproof performance. When it is necessary to disassemble the connecting shell 213, the sealing cover 205 is rotated to remove it first. To remove the glider body 302, slide the limiting post 211. The limiting post 211 drives the first protrusion 210 to slide. At the same time, rotate the limiting post 211. Under the action of the first spring 209, the limiting post 211 engages with the limiting groove 208, and the sliding connecting shell 213 can be disassembled. When it is necessary to disassemble the glider body 302, slide the connecting post 307. The connecting post 307 can drive the second protrusion 306 to slide, thereby separating the second protrusion 306 from the glider body 302. Slide the glider body 302 to separate the glider body 302 from the wing support 301. Similarly, the glider body 302 can be installed.
