Description

Technical Field

[0001] This utility model relates to the field of underwater vehicles, and in particular to a segmented connection structure for the pressure-resistant hull of an underwater vehicle. Background Technology

[0002] With the scarcity of land resources and continuous technological advancements, countries around the world have increasingly focused on deep-sea exploration as a key research area. Deep-sea unmanned vehicles (UAVs) play an indispensable role in this exploration. A crucial challenge in the development of deep-sea UAVs is overcoming the harsh, high-pressure working environment created by water depth. Currently, pressure chambers are commonly used to protect the internal equipment of deep-sea vehicles from the pressure and corrosion of seawater.

[0003] Currently, the main structural forms of modern pressure tanks include spherical, cylindrical, and ellipsoidal shapes. Compared with other types of pressure tanks, cylindrical pressure tanks are closer to the shape of the aircraft, have low fluid resistance, are easy to process and manufacture, and, more importantly, facilitate the internal compartment layout and have high internal space utilization. Therefore, they are widely used in the development of various aircraft.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the installation and maintenance of equipment inside the pressure hull of underwater vehicles in the existing technology is not very convenient. When a certain device inside the pressure hull needs maintenance, its outer shell needs to be disassembled first, which is quite cumbersome. Utility Model Content

[0005] To address the inconvenience of installing and maintaining equipment inside the pressure hull of underwater vehicles in existing technologies, where maintenance of a device inside the pressure hull requires disassembling its outer shell, which is cumbersome, this application provides a segmented connection structure for the pressure hull of an underwater vehicle.

[0006] This application provides a segmented connection structure for the pressure hull of an underwater vehicle, using the following technical solution: A segmented connection structure for the pressure hull of an underwater vehicle includes a pressure cover. The surface of the pressure cover is provided with a limiting component, and the side surface of the pressure cover is provided with a connecting component. The limiting component includes an outer shell disposed on the surface of the pressure cover, and an annular cylinder is fixed to the surface of the outer shell. The annular cylinder has a protruding post inside, and a pull rod is fixed to the surface of the protruding post. A through hole is opened on the side surface of the pull rod. A spring is disposed inside the annular cylinder, and a sealing element is fixed to the inner wall of the annular cylinder. The limiting component also includes a concave ring fixed to the surface of the pressure hull body, and a circular block is fixed to the inner wall of the concave ring.

[0007] Furthermore, the side surface of the outer casing is provided with a connector, and the connector and the surface of the outer casing are provided with multiple sets of threaded holes.

[0008] Furthermore, the protruding post passes through the outer shell and the circular block in sequence and extends into the interior of the circular block, and the concave ring and the pressure-resistant shell body are an integrated structure.

[0009] Furthermore, the surface of the spring contacts the surface of the protrusion, and the pull rod is fixed to the protrusion by means of threads.

[0010] Further, the connecting assembly includes a pressure-resistant housing body disposed on the side surface of the pressure-resistant cover, and an L-ring is fixed to the right end of the inner wall of the pressure-resistant housing body, an L-ring is fixed to the left end of the inner wall of the pressure-resistant housing body, and a retaining ring is provided on the surface of the pressure-resistant housing body, with bolts and nuts provided on the surface of the retaining ring, and a connecting ring is fixed on the surface of the pressure-resistant housing body.

[0011] Furthermore, the side surface of the second L-ring is fitted to the surface of the first L-ring, and a sealing ring is provided at the connection between the first L-ring and the second L-ring.

[0012] Furthermore, the retaining rings are provided in multiple sets and are arranged symmetrically to each other, with the surface of the retaining rings fitting against the inner wall of the outer shell.

[0013] Compared with related technologies, the pressure hull segment connection structure for underwater vehicles provided by this utility model has the following advantages:

[0014] This utility model provides a segmented connection structure for the pressure-resistant shell of an underwater vehicle. By setting a limiting component on the surface of the pressure cover, and the limiting component having an outer shell and an annular cylinder inside, when the user slides the protruding post, the protruding post separates from the circular block on the surface of the concave ring. By sliding the outer shell, the outer shell can be disassembled, making the disassembly of the outer shell simple.

[0015] This utility model provides a segmented connection structure for the pressure hull of an underwater vehicle. By providing L-ring one and L-ring two inside the connection component, the sealing performance at the connection between the two pressure hull bodies is improved. Since the pressure hull body adopts a segmented structure, the structure is ingenious and has good assembly performance, which facilitates the installation and disassembly of internal equipment. It is suitable for the development of various deep-sea unmanned vehicles. Attached Figure Description

[0021] 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.

[0022] Example 1:

[0023] like Figure 1-4 As shown, the present invention discloses a segmented connection structure for a pressure-resistant shell of an underwater vehicle, including a pressure-resistant cover 1. The surface of the pressure-resistant cover 1 is provided with a limiting component 2, and the side surface of the pressure-resistant cover 1 is provided with a connecting component 3. The limiting component 2 includes an outer shell 201 provided on the surface of the pressure-resistant cover 1, and an annular cylinder 202 is fixed on the surface of the outer shell 201. The inside of the annular cylinder 202 is provided with a protruding post 203, and a pull rod 204 is fixed on the surface of the protruding post 203. The side surface of the pull rod 204 is provided with a through hole 205. The inside of the annular cylinder 202 is provided with a spring 206, and a sealing element 207 is fixed on the inner wall of the annular cylinder 202. The limiting component 2 also includes a concave ring 208 fixed on the surface of the pressure-resistant shell body 301, and a round block 209 is fixed on the inner wall of the concave ring 208.

[0024] like Figure 1-4 As shown, the side surface of the outer casing 201 is provided with a connector 210, and the connector 210 and the surface of the outer casing 201 are provided with multiple sets of threaded holes 211.

[0025] like Figure 1-4 As shown, the protruding post 203 passes through the outer shell 201 and the circular block 209 in sequence and extends into the interior of the circular block 209. The concave ring 208 and the pressure-resistant shell body 301 are an integrated structure.

[0026] like Figure 1-4 As shown, the surface of the spring 206 is in contact with the surface of the protrusion 203, and the pull rod 204 forms a fixed structure with the protrusion 203 through threads.

[0027] During implementation, when it is necessary to disassemble the outer shell 201, the sliding rod 204 can drive the protrusion 203 to slide, thereby separating the protrusion 203 from the circular block 209 on the surface of the concave ring 208. By sliding the outer shell 201, the outer shell 201 can be disassembled. At the same time, the annular cylinder 202 is equipped with a spring 206 and a seal 207 inside. During installation, the spring 206 can push the protrusion 203 to reset. Installation and disassembly are simple. Due to the integrated design of the outer shell 201 and the annular cylinder 202, the openings of the outer shell 201 are reduced, thereby improving the pressure resistance of the entire outer shell 201.

[0028] Example 2:

[0029] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: the connecting component 3 includes a pressure-resistant housing body 301 disposed on the side surface of the pressure-resistant cover 1, and an L-ring 302 is fixed to the right end of the inner wall of the pressure-resistant housing body 301, an L-ring 303 is fixed to the left end of the inner wall of the pressure-resistant housing body 301, and a retaining ring 304 is provided on the surface of the pressure-resistant housing body 301, a bolt and nut 305 is provided on the surface of the retaining ring 304, and a connecting ring 306 is fixed on the surface of the pressure-resistant housing body 301.

[0031] like Figure 1-4 As shown, multiple sets of retaining rings 304 are provided, and the retaining rings 304 are arranged symmetrically to each other. The surface of the retaining rings 304 is in contact with the inner wall of the outer shell 201.

[0032] In practice, the inner wall of the pressure hull body 301 is provided with L-ring 302 and L-ring 303, and L-ring 302 and L-ring 303 are interlocked. A sealing ring 307 is provided at the connection between L-ring 302 and L-ring 303, which improves the sealing performance at the connection between the two sets of pressure hull bodies 301. Since the pressure hull body 301 adopts a segmented structure, it has a clever structure, good assembly performance, and facilitates the installation and disassembly of internal equipment. It is suitable for the development of various deep-sea unmanned vehicles.

[0033] The advantages of this technical solution in practical applications include, but are not limited to, the following:

[0034] 1. The limiting component 2 has an outer shell 201 and an annular cylinder 202 inside, so that when the user slides the protruding post 203, the protruding post 203 is separated from the round block 209 on the surface of the concave ring 208. The outer shell 201 can be disassembled by sliding the outer shell 201, and the outer shell 201 is easy to disassemble.

[0035] 2. The connection component 3 is equipped with L-ring 302 and L-ring 303, which improves the sealing performance of the connection between the two pressure-resistant shell bodies 301. Since the pressure-resistant shell body 301 adopts a segmented structure, it has a clever structure, good assembly performance, and facilitates the installation and disassembly of internal equipment. It is suitable for the development of various deep-sea unmanned vehicles.

[0036] In this technical solution, when the outer shell 201 needs to be disassembled, the sliding rod 204 can be used to drive the protrusion 203 to slide, thereby separating the protrusion 203 from the circular block 209 on the surface of the concave ring 208. By sliding the outer shell 201, the outer shell 201 can be disassembled. At the same time, the annular cylinder 202 is equipped with a spring 206 and a seal 207 inside. During installation, the spring 206 can push the protrusion 203 to return to its original position. Installation and disassembly are simple. Due to the integrated design of the outer shell 201 and the annular cylinder 202, the number of openings in the outer shell 201 is reduced. This improves the pressure resistance of the entire outer shell 201. The inner wall of the pressure-resistant shell body 301 is provided with L-ring 1 302 and L-ring 2 303, and L-ring 1 302 and L-ring 2 303 are interlocked. A sealing ring 307 is provided at the connection between L-ring 1 302 and L-ring 2 303, which improves the sealing performance at the connection between the two sets of pressure-resistant shell bodies 301. Since the pressure-resistant shell body 301 adopts a segmented structure, it has a clever structure, good assembly performance, and facilitates the installation and disassembly of internal equipment. It is suitable for the development of various deep-sea unmanned vehicles.
