Description

Technical Field

[0001] This invention belongs to the field of submersible technology, specifically relating to a tooling and method for disassembling and assembling a submersible sealing cover. Background Technology

[0002] During ocean exploration, AUVs often need to dive to greater depths for exploration. AUV (autonomous underwater vehicle) is an autonomous underwater vehicle or an autonomous underwater vehicle.

[0003] If an AUV is equipped with large equipment and instruments such as high-precision inertial navigation systems and gravimeters, it will result in a very large cabin diameter, and the corresponding diameter of the sealing caps at the front and rear of the cabin will also increase. At the same time, in deep-sea operations, the sealing caps need to be thickened to withstand the pressure of deep-sea water, resulting in a heavy overall weight of the sealing caps. It is difficult to disassemble and assemble the sealing caps by hand, and reliable tooling equipment is required.

[0004] In addition, because a sealing ring is squeezed between the sealing cover and the cabin, the deformation force generated by the sealing ring after being squeezed is relatively large. This means that a large force is required to overcome the deformation force of the sealing ring during the installation and disassembly of large-sized sealing covers. Furthermore, the sealing cover cannot be guaranteed to move axially continuously during installation and disassembly, which may cause damage to the sealing cover.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0035] Example 1 See Figures 1-9 This is an embodiment of a tooling device for disassembling and assembling a submersible sealing cover proposed in this invention, wherein... Figures 1-5 This is a schematic diagram showing the installation of the sealing cap 220. Figures 7-9 This is a schematic diagram illustrating the removal of the sealing cover. The submersible 200 has a cabin 210 and a detachable sealing cover 220 located at the end of the cabin 210. The sealing cover 220 is installed inside the cabin 210; sealing covers 220 can be provided on both the left and right sides of the cabin 210, or only one sealing cover can be provided. The cabin 210 is cylindrical, with the direction closer to the axis of the cabin 210 being inward, and the opposite direction being outward; the sealing cover 220 is installed on the inner side of the cabin wall of the cabin 210. The cabin 210 can be provided with one sealing cover 220 or two sealing covers 220 as needed. To facilitate the installation and removal of the sealing cover 220, a tooling device 100 for removing and installing the submersible sealing cover is proposed.

[0036] The disassembly tooling equipment 100 includes: a first bracket 10, a second bracket 20, and multiple connecting rods 30. The first bracket 10 is located at one end of the cabin 210 where the sealing cover 220 needs to be installed, and the second bracket 20 is located at the other end of the cabin 210. The multiple connecting rods 30 are detachably connected between the first bracket 10 and the second bracket 20. The first bracket 10 has multiple first connecting portions 13 extending outward from the cabin 210, meaning the first bracket 10 abuts against the end of the cabin 210. The second bracket 20 has multiple second connecting portions 23 extending outward from the cabin 210. The connecting rods 30 connect the oppositely arranged first connecting portions 13 and second connecting portions 23. The number of first connecting portions 13, second connecting portions 23, and connecting rods 30 is the same. One end of each connecting rod 30 is fixedly connected to the first connecting portion 13, and the other end is fixedly connected to the second connecting portion 23.

[0037] The first bracket 10 is provided with multiple pushing structures for pushing the sealing cover 220 to move in the installation direction. Each pushing structure has a pushing hole 14 opened on the first bracket 10 and a pushing screw 15 that matches the pushing hole 14. By rotating the pushing screw 15, the sealing cover 220 is pushed to move.

[0038] In this embodiment, by setting the first bracket 10, the second bracket 20 and multiple connecting rods 30, the rotation and movement of multiple push screws 15 can realize the smooth movement of the sealing cover 220 during the installation process. This helps to ensure that the sealing cover 220 moves in the axial direction of the cabin 210, avoids damage to the sealing ring on the sealing cover 220 during the installation process, and ensures the sealing performance after installation.

[0039] In some embodiments of this application, multiple pushing structures are evenly arranged in the circumferential direction of the first support 10. When multiple pushing structures simultaneously apply pushing force to the sealing cover 220, it is beneficial for the sealing cover 220 to be subjected to uniform force in the circumferential direction, thus ensuring that the sealing cover 220 moves in the axial direction of the cabin 210.

[0040] In some embodiments of this application, a force-receiving block 225 matching the push screw 15 is provided on the sealing cover 220. One end of the push screw 15 abuts against the force-receiving block 225, and the push screw 15 transmits force to the force-receiving block 225 in contact with it. The force-receiving block 225 protrudes from the sealing cover 220, resulting in a larger thickness of the sealing cover 220 at the force-receiving block 225, which is beneficial to improving the force-bearing capacity. A matching force-transmitting structure is provided between the end of the push screw 15 and the force-receiving block 225. The force-transmitting structure consists of a protrusion 151 provided at the end of the push screw 15 and a groove 2251 provided on the force-receiving block 225, with the protrusion 151 and the groove 225 being matched. By setting the protrusion 151 and the groove 225, it is beneficial to increase the contact area between the push screw 15 and the force receiving block 225; and the protrusion 151 is wrapped in the groove 225, which ensures that the force on the push screw 15 is applied to the force receiving block 225, and ensures the axial movement of the push screw 15.

[0041] In some embodiments of this application, the force transmission structure may also be a protrusion on the force-receiving block 225 and a groove on the push screw 15.

[0042] In some embodiments of this application, the force-bearing block 225 is a detachable bolt mounted on the sealing cover 220. The sealing cover 220 has a mounting hole 221 with an internal thread matching the bolt. The bolt is screwed into the mounting hole 221. By making the force-bearing block 225 detachable, a harder material can be chosen for the force-bearing block 225, which is more conducive to withstanding pressure. Furthermore, after the force-bearing block 225 is removed, the mounting hole 221 can be used to remove the sealing cover 220.

[0043] In some embodiments of this application, a push cap 152 for applying torque is provided at the end of the push screw 15 away from the sealing cover 220. Torque can be applied by manually applying a tool to the push cap 152.

[0044] In some embodiments of this application, a first limiting pin 16 located on the outside of the cabin 210 is provided on the first connecting portion 13, and the first limiting pin 16 is provided on multiple first connecting portions 13; when the first bracket 10 is assembled onto the cabin 210, the sealing cover 220 is first placed at the end of the cabin 210, and the sealing cover 220 is located inside the cabin 210. The sealing cover 220 needs to continue to move axially toward the center of the cabin 210 to reach the installation position; then the first bracket 10 is brought close to the cabin 210, so that the first bracket 10 abuts against the end of the cabin 210, and multiple first limiting pins 16 are all located on the outside of the cabin 210, realizing the radial positioning and axial positioning of the first bracket 10 abutting against the cabin 210.

[0045] A second limiting pin 26 is provided on the second connecting part 23, located on the outside of the cabin 210. When the second bracket 20 is assembled onto the cabin 210, the second bracket 20 and the first bracket 10 are arranged opposite each other. The second bracket 20 is brought close to the cabin 210, so that the second bracket 20 abuts against the end of the cabin 210, and the multiple second limiting pins 26 are all located on the outside of the cabin 210, realizing the radial positioning and axial positioning of the second bracket 20 abutting against the cabin 210.

[0046] In some embodiments of this application, a first connecting hole 131 matching the connecting rod 30 is provided on the first connecting portion 13, and a second connecting hole 231 matching the connecting rod 30 is provided on the second connecting portion 23. External threads are provided at both ends of the connecting rod 30, and a first connecting nut 31 and a second connecting nut 32 matching the external threads. The connecting rod 30 is fixed to the first connecting portion 13 and the second connecting portion 23 by the first connecting nut 31 and the second connecting nut 32.

[0047] In some embodiments of this application, an annular mounting platform 211 extending radially inward is provided inside the cabin 210, and the sealing cover 220 has a cover body 229 and an outwardly extending mounting edge 228 along the side of the cover body 229 away from the center of the cabin 210. The mounting edge 228 is fixed to the mounting platform 211 by fasteners; the cover body 229 is located inside the mounting platform 211.

[0048] In some embodiments of this application, the sealing cover 220 further has a reinforcing edge 227 extending along the outer side of the cover body 229 towards the center of the compartment 210. A sealing ring 224 is provided between the reinforcing edge 227 and the mounting platform 211, and an annular sealing groove for accommodating the sealing ring 224 is formed on the reinforcing edge 227. By providing the reinforcing edge 227, it is beneficial to increase the axial mating area between the sealing cover 220 and the compartment 210, and to increase the structural strength of the sealing cover 220. The disassembly tooling device 100 is mainly used to push the sealing cover 220 and the mounting platform 211 for mating installation or disassembly.

[0049] In some embodiments of this application, the sealing cover 220 further includes an annular reinforcing rib 223 extending along the cover body 229 towards the center of the hull 210, and a plurality of radial reinforcing ribs 222 connecting the annular reinforcing rib 223 and the reinforcing edge 227. The inclusion of reinforcing ribs improves the structural strength of the sealing cover 220. The cover body 229 is an arc-shaped structure protruding from the center away from the center of the hull 210, which improves the sealing cover 220's ability to withstand underwater pressure.

[0050] In some embodiments of this application, the disassembly tooling device 100 further includes a disassembly screw 25 for disassembling the sealing cover. A through hole 24 is provided on the second bracket 20 for the disassembly screw 25 to pass through. The end of the disassembly screw 25 is detachably fastened to the sealing cover 220. A disassembly nut 27 is also provided on the disassembly screw 25, located on the side of the through hole 24 away from the sealing cover 220. When it is necessary to disassemble the sealing cover 220, the second bracket 20 is abutted against the bottom of the chamber 210 and positioned by the second limiting pin 26. Then, the disassembly screw 25 is passed through the through hole 24 and fixed to the sealing cover 220. Next, the disassembly nut 27 is installed on the disassembly screw 25 and rotated so that the disassembly nut 27 abuts against the sealing cover 220. Finally, by tightening the disassembly nut 27, the sealing cover 220 is moved closer to the second bracket 20. When removing the sealing cover 220, place the second bracket 20 on the end of the compartment 210 where the sealing cover 220 needs to be removed.

[0051] The number of disassembly screws 25 can be set to one or more. In this embodiment, three disassembly screws 25 are provided, which are evenly arranged axially.

[0052] In some embodiments of this application, the disassembly nut 27 may be installed onto the disassembly screw 25 first, and then the disassembly screw 25 may be passed through the through hole 24.

[0053] In some embodiments of this application, a mounting hole 221 matching the disassembly screw 27 is provided on the sealing cover 220. The internal thread of the mounting hole 221 and the internal thread of the disassembly nut 27 are threads that rotate in the same direction; this ensures that the disassembly screw 25 is not disassembled from the mounting hole 221 when the disassembly nut 27 is tightened.

The sealing cover 220 is moved toward the center of the compartment 210 by rotating and pressing the multiple push screws 15 until the sealing cover 220 is in place.

[0055] The sealing cover 220 can be pushed into place using the above method, and then fixed to the mounting platform 211 using fasteners, thus achieving the installation and fixation of the sealing cover 220.

[0056] The disassembly and assembly method also includes the step of removing the sealing cap 220: S210.
