Description

Technical Field

[0001] This invention relates to the field of optical cable installation components, specifically a micro-optical cable installation component for a full-ocean-depth unmanned submersible. Background Technology

[0002] A full-ocean-depth unmanned submersible (UUV) is a diving device with underwater observation and operational capabilities. It is used to perform tasks such as underwater surveys, seabed exploration, seabed development and salvage, and rescue. It can also serve as an operational base for underwater activities for divers. It can accomplish a variety of complex tasks, including surveying seabed resources through photography and videography, deploying underwater equipment at designated locations, and inspecting submarine cables and pipelines. In the construction of full-ocean-depth UUVs, the use of micro-fiber optic cable structures is an important component. However, due to the installation environment, some existing micro-fiber optic cable installation components for full-ocean-depth UUVs still have certain shortcomings in their use, resulting in deficiencies in the installation of micro-fiber optic cables within full-ocean-depth UUVs.

[0003] Patent document CN215006011U discloses an installation assembly suitable for optical cables, "including an optical cable fixing module for assembly within an optical cable distribution box. The optical cable fixing module includes multiple fixing components and a top cover. The fixing components are stacked sequentially. The top surface of each fixing component has a buckle and a fixing groove for placing the optical cable. The bottom surface of each fixing component has a buckle groove adapted to the buckle. Two adjacent fixing components are fixed by the buckle and the buckle groove. The bottom surface of the top cover also has a buckle groove. The top cover is fixed to the uppermost fixing component by the buckle groove of the top cover and the buckle of the fixing component. This application can solve the problem of cumbersome, time-consuming, and labor-intensive operation caused by using cable ties to bind optical cables in related technologies for optical cable installation." However, in the aforementioned patent, when the device is used for cable installation, the cable laying is affected by the installation environment. The disorder of cable laying can easily lead to tangling between cables, thus posing a safety hazard. The cables lack independent installation environments and affect each other. Therefore, the aforementioned device lacks a safe and suitable installation structure when installing cables, making it difficult to meet the installation requirements inside a full-ocean-depth unmanned submersible.

[0012] Preferably, the device is used as follows: S1. When the device is in use, the fixed frame is fixedly installed in the cable laying area by setting the bottom plate and fixing bolts on the positioning plates on both sides, and then the fixed frame is installed and fixed. Multiple sets of fixed frames are installed at equal intervals according to the laying area. The inner wall of the fixed frame is opened with a limiting groove, and the sliding strip slides within the limiting groove, thereby adding the sliding use of the sliding seat within the fixed frame. The protective sleeve is installed through the inside of the sliding seat, and after the protective sleeve passes through the sliding seat, its tail end also passes through the inside of the limiting frame. The cable body passes through the inside of the protective sleeve. Inside the protective sleeve, the positioning slider moves... The sliding properties within the positioning groove allow the floating plate to slide up and down within a certain range. The front end of the floating plate is connected to an inner tube. The top and bottom of the floating plate are connected by a pressing block, a pressing tube, and a pressing spring. The pressing block slides within the pressing tube, and the pressing spring is installed inside the pressing tube. After connecting to the pressing block, the spring limits the vertical movement of the floating plate. The outer surface of the protective sleeve is fitted with a reinforcing ring. After the reinforcing ring is fitted, it is fixed by the bottom base and reinforcing bolts. With the help of the fixing bolts, the device is installed and fixed in the area where cables are laid.

[0013] S2. After the fixed frame is installed and fixed by the structure on the positioning plate, the fixed frames are placed at equal intervals according to the installation quantity requirements. The spacing between the positioning plates is achieved by setting the connecting seat and the support rod. The two ends of the support rod are snapped into the inside of the connecting seat by snapping. Then, when placing the fixed frame, the front and rear spacing is limited and fixed. The top of the reinforcing ring is set by the snap seat, which has a snap groove, so that the snap block is snapped and installed. Then, the connecting plate is installed and connected. After the connecting plate is snapped and installed on the snap seat by its bottom snap block, the spacing on both sides of the protective sleeve is limited and fixed.

[0014] S3. The cable body passing through the inner tube is the cable body wound on the bundling shaft. When the cable body is laid and used, one end of the cable body passes through the cable tie hole on the bogie and then passes into the inner tube. After the cable body passes through the cable tie hole, the cleaning ring and the annular scraper scrape off any foreign objects on the cable body when the cable body is pulled out. The two sets of bundling shafts are used for hand-held laying of the cable body by limiting handles.

[0015] S4. After the spacing between the fixed frame and the protective sleeve is limited and fixed, a magnetic suction plate is provided on the top of the connecting plate, and an iron material is provided on the bottom of the load-bearing plate. The load-bearing plate is then magnetically connected to the magnetic suction plate on the connecting plate. After the cable is laid, the load-bearing plate is laid on the top of the fixed frame to cover the top of the fixed frame and the limiting frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention allows for convenient and reasonable adjustment of cable laying spacing through the sliding adjustment of the sliding seat within the fixed frame and the adjustability of the positioning plate's installation position on the fixed frame. Furthermore, the protective sleeve, with its reinforcing ring, is detached from the fixed frame and installed independently, enhancing the device's applicability during cable laying. In use, the convenient spacing adjustment avoids the tangling problem caused by excessive cable contact, improves the safety of separate cable laying, and facilitates orderly cable laying, making flat cable laying more convenient. The multi-layered external frame structure also provides excellent protection for the cable structure.

[0017] 2. The present invention uses an annular scraper with a hole diameter slightly larger than that of the cable body. Therefore, when the cable body is pulled out, it scrapes off any foreign objects on the cable body, cleans the foreign objects adhering to the surface of the cable body when it is placed, and also detects the protrusions on the surface of the cable body to detect whether the cable body is damaged, so as to cut and replace it in time.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8A micro-optical cable installation assembly for a full-ocean-depth unmanned submersible includes a fixed frame 1, with positioning plates 2 fixedly installed on both sides of the fixed frame 1, a limit frame 3 fixedly installed on the back of the fixed frame 1, a limit groove 4 formed on the inner wall of the fixed frame 1, a sliding seat 5 slidably connected to the inner wall of the limit groove 4, sliding strips 32 fixedly installed on the top and bottom of the sliding seat 5, and the sliding strips 32 slidably connected to the inside of the limit groove 4, a protective sleeve 6 penetrating the inside of the sliding seat 5, two sets of floating plates 7 slidably connected to the inner wall of the protective sleeve 6, an inner tube 8 fixedly installed on the facing surfaces of the two sets of floating plates 7, a cable body 9 penetrating the inside of the inner tube 8, positioning sliders 10 fixedly installed on the separating surfaces of the two sets of floating plates 7, two sets of positioning grooves 11 formed on the inner wall of the sliding seat 5, and the positioning sliders 10 slidably connected to the inside of the positioning grooves 11, the top and bottom of the floating plates 7... Each part is fixedly installed with a pressing block 12. The outer surface of the pressing block 12 is fitted with a pressing tube 13, and the tail end of the pressing tube 13 is fixedly connected to the inner wall of the sliding seat 5. The inner wall of the pressing tube 13 is fixedly installed with a pressing spring 14, and the front end of the pressing spring 14 is fixedly connected to the tail end of the pressing block 12. The bottom of the positioning plate 2 is fixedly installed with a base plate 15. The top of the base plate 15 is threaded through with multiple sets of fixing bolts 16. The outer surface of the protective sleeve 6 is fitted with a reinforcing ring 17. The two sides of the reinforcing ring 17 are threaded through with control bolts 40. The front end of the control bolts 40 is rotatably connected to a limit clamp 41. The top and bottom of the limit clamp 41 are fixedly installed with connecting sliders 42, and the connecting sliders 42 are slidably connected to the inside of the reinforcing ring 17. The bottom of the reinforcing ring 17 is fixedly installed with a base 18. The two sides of the top of the base 18 are threaded through with reinforcing bolts 19. By setting the base plate 15 and fixing bolts 16, the positioning plate 2 is fixedly installed in the cable laying area. Then, the fixing frame 1 is installed and fixed in the cable pre-laying area. Multiple sets of fixing frames 1 are installed at equal intervals according to the laying area. The sliding strip 32 limits the sliding in the limiting groove 4, and increases the sliding usability of the sliding seat 5 in the fixing frame 1. The protective sleeve 6 is installed through the inside of the sliding seat 5. In use, the protective sleeve 6 is inserted and placed in this way, so that the placement length and direction of the protective sleeve 6 are the same as the laying direction and length of the cable. The cable body 9 passes through the inside of the protective sleeve 6. By the sliding of the positioning slider 10 in the positioning groove 11, the floating plate 7 has a certain range of up and down sliding. The top and bottom of the floating plate 7 are set by the pressing block 12, the pressing tube 13 and the pressing spring 14. The pressing block 12 slides in the pressing tube 13. The elasticity of the sleeve pressing spring 14 increases the limiting activity of the pressing block 12 in the pressing tube 13. The inner tube 8 and floating plate 7 provide a certain buffering effect when they float as described above. By increasing the mobility of the inner tube 8, the cable structure is given appropriate mobility during cable laying to adapt to the installation requirements in dynamic environments. The outer surface of the protective sleeve 6 is fitted with the reinforcing ring 17. After the reinforcing ring 17 is fitted, it is fixed by the bottom base 18 and the reinforcing bolt 19. With the help of the fixing bolt 16, the device is installed and fixed in the cable laying area, thereby limiting the position of the protective sleeve 6. The control bolt 40 on the reinforcing ring 17 pushes the limiting clamp 41. The sliding property of the connecting slider 42, combined with the rotational connection between the limiting clamp 41 and the control bolt 40, assists the sliding of the limiting clamp 41. The sliding of the limiting clamp 41 clamps and fixes the protective sleeve 6. Based on the installation and fixation of the reinforcing ring 17, the installation position of the protective sleeve 6 is fixed.

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8The front and back of the positioning plate 2 are fixedly installed with connecting seats 20. The connecting seats 20 are internally connected with support rods 21. The top of the reinforcing ring 17 is fixedly installed with a snap-fit ​​seat 22. The top of the snap-fit ​​seat 22 has two sets of snap-fit ​​grooves 23. The top of the snap-fit ​​seat 22 is connected with a connecting plate 24. The bottom of the connecting plate 24 is fixedly installed with a snap-fit ​​block 33, which is snapped into the inside of the snap-fit ​​groove 23. The top of the connecting plate 24 is movably installed with a magnetic suction plate 25. The bottom of the connecting plate 24 is fixedly installed with a snap-fit ​​block 33, which is snapped into the inside of the snap-fit ​​groove 23. The top of the magnetic suction plate 25 is magnetically connected with a load-bearing plate 34. The top of the load-bearing plate 34 is fitted with an anti-slip plate 35. One side of the load-bearing plate 34 is fixedly installed with a docking plate 36, and the other side of the load-bearing plate 34 has a docking groove 37. After the fixed frame 1 is fixed by the structure on the positioning plate 2, it is installed at equal intervals according to the required number of installations. The spacing between the positioning plates 2 is achieved by the connection seat 20 and the support rod 21. The two ends of the support rod 21 are snapped into the inside of the connection seat 20 by snap-fit, thereby limiting and fixing the front and rear spacing of the fixed frame 1 when it is placed. The top of the reinforcing ring 17 is provided by the snap-fit ​​seat 22, which has a snap-fit ​​groove 23, so as to snap-fit ​​the snap-fit ​​block 33. Then, the connecting plate 24 is installed and connected by the snap-fit ​​block 33 at its bottom. After the snap-fit ​​installation on the snap-fit ​​seat 22, the spacing on both sides of the protective sleeve 6 is limited and fixed. After the spacing between the fixing frame 1 and the protective sleeve 6 is limited and fixed, the top of the connecting plate 24 is provided with a magnetic suction plate 25, and the bottom of the load-bearing plate 34 is provided with iron material, which is magnetically connected to the magnetic suction plate 25 on the connecting plate 24. The installation connection between the connecting plate 24 and the magnetic suction plate 25 ensures that the two sets of protective sleeves 6 maintain an appropriate spacing, which plays a role in spacing control for cable laying. It also ensures that the sliding seat 5 is equidistantly distributed within the limiting frame 3, so that most cables maintain an orderly laying spacing when being laid.

[0022] Please see Figure 1 , Figure 2 , Figure 3 and Figure 9 The cable body 9 is wound and connected to the outer surface of the bundling shaft 26. The top and bottom of the bundling shaft 26 are rotatably mounted with limit covers 27. The two sets of limit covers 27 are rotatably connected to the opposite surfaces of the two sets of limit covers 27. The top of the bogie 28 is fixedly mounted with a reinforcing rod 38. The top of the reinforcing rod 38 is fixedly mounted with a limit handle 39. The front of the bogie 28 is provided with a cable harness hole 29, and the cable body 9 passes through the inside of the cable harness hole 29. The inner wall of the bogie 28 is fixedly mounted with a cleaning ring 30, and the cleaning ring 30 is positioned corresponding to the cable harness hole 29. The inner wall of the cleaning ring 30 is fixedly mounted with an annular scraper 31. The cable body 9 passing through the inner tube 8 is the same cable body 9 wound on the bundling shaft 26. Therefore, the bundling shaft 26 is a storage device for the cable body 9. During laying and use, one end of the cable body 9 is pulled to pass through the cable tie hole 29 on the bogie 28. By continuously pulling out the sleeve, the cable body 9 is pulled out a certain distance, and then one end is inserted into the inner tube 8. After the cable body 9 passes through the cable tie hole 29, the sleeve is stopped by the retaining handle 39. When the cable is held in hand and the bundling shaft 26 is used, the rotation of the bundling shaft 26 continuously extends the service length of the cable body 9. When the cable body 9 is pulled out for use, the cleaning ring 30 and the annular scraper 31 are used. After the cable body 9 passes through the cable bundling hole 29, the surface of the cable body 9 will come into contact with the annular scraper 31. The diameter of the hole of the annular scraper 31 is slightly larger than the diameter of the cable body 9. Therefore, when the cable body 9 is pulled out, the excess foreign matter on the cable body 9 is scraped off, the foreign matter adhering to the surface of the cable body 9 when it is placed is cleaned, and the protrusions on the surface of the cable body 9 are also detected to detect whether the cable body 9 is damaged, so that it can be cut off and replaced in time.

[0023] Working principle: During use, the fixed frame 1 is fixedly installed in the cable laying area by the base plate 15 and fixing bolts 16 on the positioning plates 2 on both sides, thereby fixing the positioning plates 2. Multiple sets of fixed frames 1 are installed at equal intervals according to the laying area. The inner wall of the fixed frame 1 is limited by the opening of the limiting groove 4, and the sliding strip 32 slides within the limiting groove 4. This allows the sliding seat 5 to slide within the fixed frame 1. The protective sleeve 6 is installed through the inside of the sliding seat 5, and its tail end also passes through the inside of the limiting frame 3. The cable body 9 passes through the inside of the protective sleeve 6. The sliding of the positioning slider 10 within the positioning groove 11 within the protective sleeve 6 allows the cable body 9 to slide through the protective sleeve 6. The floating plate 7 has a certain range of vertical sliding. The front end of the floating plate 7 is installed through the inner tube 8. The top and bottom of the floating plate 7 are connected by pressing blocks 12, pressing tubes 13, and pressing springs 14. The pressing blocks 12 slide inside the pressing tubes 13, and the pressing springs 14 are installed inside the pressing tubes 13. After connecting to the pressing blocks 12, the vertical floating position of the floating plate 7 is limited. The outer surface of the protective sleeve 6 is fitted with the reinforcing ring 17. After the reinforcing ring 17 is fitted, it is fixed by the bottom base 18 and the reinforcing bolts 19. With the help of the fixing bolts 16, the device is installed and fixed in the area where the cable is laid. The fixing frame 1 is fixed by the installation structure on the positioning plate 2. After the installation is completed, the fixed frames 1 are installed at equal intervals according to the required number of installations. The spacing between the positioning plates 2 is achieved through the connection seat 20 and the support rod 21. The two ends of the support rod 21 are snapped into the inside of the connection seat 20 by snapping. Then, when the fixed frames 1 are placed, their front and rear spacing is limited and fixed. The top of the reinforcing ring 17 is connected by a snap-fit ​​seat 22, which has a snap-fit ​​groove 23, so that the snap-fit ​​block 33 is snapped and installed. Then, the connecting plate 24 is installed and connected. After the connecting plate 24 is snapped and installed on the snap-fit ​​seat 22 by its bottom snap-fit ​​block 33, the spacing on both sides of the protective sleeve 6 is limited and fixed. After the spacing between the fixed frame 1 and the protective sleeve 6 is limited and fixed, the top of the connecting plate 24... The unit is equipped with a magnetic suction plate 25, and the bottom of the load-bearing plate 34 is provided with iron material, which is magnetically connected to the magnetic suction plate 25 on the connecting plate 24. Then, after the cable is laid, the load-bearing plate 34 is laid on the top of the fixed frame 1, covering the top of the fixed frame 1 and the limiting frame 3. After the installation and fixation of the device frame structure is completed, a reasonable laying environment is provided for the cable body 9. The cable body 9 passing through the inner tube 8 is the cable body 9 wound on the bundling shaft 26. When the cable body 9 is laid and used, one end of it passes through the cable bundling hole 29 on the bogie 28 and then passes into the interior of the inner tube 8. After the cable body 9 passes through the cable bundling hole 29, it is cleaned by the cleaning ring 30 and the annular scraper 31. When the cable body 9 is pulled out,The annular scraper 31 scrapes away any foreign objects on the cable body 9, and the two sets of bundling shafts 26 are used for hand-laying the cable body 9 via the limiting handles 39.
