Description

A submarine cable construction equipment Technical Field

[0001] This invention relates to the field of cable laying technology, and more specifically, to a submarine cable construction device. Background Technology

[0002] As a core infrastructure for marine power transmission and communication connections, the construction quality of submarine cables directly determines the stability and security of marine energy development and cross-sea communication. The underwater construction environment is extremely complex, facing not only high pressure, high humidity, and highly corrosive seawater erosion, but also terrain challenges such as uneven seabed, soft silt deposits, and reef obstacles. This places extremely high demands on the stability of construction equipment, the precision of cable clamping and guiding, the accuracy of laying, and the reliability of waterproofing.

[0003] Existing submarine cable laying equipment suffers from the following problems: Firstly, the underwater movement stability of existing equipment is insufficient. Most existing equipment uses traditional wheeled walking structures, which cannot guarantee continuous and stable movement. Secondly, the cable clamping and guiding flexibility and adaptability are poor. The cable clamping and guiding structures of existing equipment are mostly designed with fixed dimensions, which cannot accommodate submarine cables of different diameters. Cables are prone to twisting and deviation during transport, resulting in poor laying performance. Thirdly, the laying components of existing equipment are mostly fixed guiding structures, unable to flexibly adjust the cable lowering angle and depth according to changes in seabed topography. Furthermore, the walking and cable transport are not synchronized. The walking system and cable transport system of existing equipment are mostly independently driven, and their speeds cannot be precisely matched. When the equipment walking speed is faster than the cable transport speed, the cable is pulled, potentially leading to breakage. When the walking speed is slower than the transport speed, the cable becomes loose and accumulates, resulting in poor laying performance.

[0004] Therefore, we have made improvements and proposed a submarine cable construction device to solve the problems mentioned above. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please refer to Figures 1-8. This invention proposes a submarine cable construction device, including a vehicle body 1. The lower end of the vehicle body 1 is symmetrically and fixedly connected to two connecting arms 2. Each connecting arm 2 is equipped with a traveling mechanism 3. The upper end of the vehicle body 1 is fixedly connected to a first mounting frame 4 and a second mounting frame 5. A fixed horizontal roller 6 is rotatably connected inside both the first mounting frame 4 and the second mounting frame 5. A vertical pressing component 7 is provided on the upper side of each fixed horizontal roller 6. A fixed vertical roller 8 that cooperates with the fixed horizontal roller 6 is rotatably connected inside both the first mounting frame 4 and the second mounting frame 5. The fixed vertical roller 8 is located on one side of the fixed horizontal roller 6. A lateral pressing component 9 is provided on one side of each fixed vertical roller 8. A laying component 10 is provided on the outer side of the second mounting frame 5. A driven gear 11 is fixedly connected to one end of the shaft of the fixed horizontal roller 6 inside the second mounting frame 5. A transmission shaft 12 is rotatably connected to the side wall of the second mounting frame 5 near the driven gear 11. A driving gear 13 that meshes with the driven gear 11 is fixedly connected to the inner end of the transmission shaft 12.

[0022] This submarine cable construction equipment achieves efficient cable laying in complex submarine terrain through the coordinated operation of multiple systems, including submarine movement, cable clamping and guidance, synchronous laying, and linkage transmission. The vehicle body 1 serves as the overall load-bearing foundation, supporting all functional components. The connecting arm 2 connects the vehicle body 1 to the traveling mechanism 3, which adapts to the uneven submarine terrain to achieve stable equipment movement. The fixed horizontal roller 6 and fixed vertical roller 8 in the first mounting frame 4 and the second mounting frame 5, together with the vertical clamping component 7 and the lateral clamping component 9, achieve stable clamping and guidance of the cable. The laying component 10 completes the precise lowering and laying of the cable. The linkage transmission system ensures that the traveling speed is synchronized with the cable conveying speed, avoiding cable pulling or loosening. The overall structure is adapted to the construction requirements of submarine high pressure and complex terrain.

[0023] As shown in Figures 1, 2, 5 and 6, the walking mechanism 3 includes a walking frame 301 fixed on the connecting arm 2. Both the front and rear ends of the walking frame 301 are rotatably connected to walking wheels 302. A track 303 is connected between the two walking wheels 302. A set of wheel seats 304 are fixedly connected at equal intervals on the upper and lower end faces of the walking frame 301. Each wheel seat 304 is rotatably connected to a support wheel 305 for supporting the track 303.

[0024] The rotation of the traveling wheel 302 drives the track 303 to rotate, thereby enabling the vehicle body 1 to move stably on the seabed. The support wheel 305 supports the track 303 to prevent it from sagging due to its own weight or the undulation of the seabed terrain, ensuring that the track 303 fits tightly with the seabed surface and improving the stability of the equipment on uneven terrain.

[0025] As shown in Figures 1, 2, 5, and 6, the walking frame 301 has two symmetrically connected and rotatably connected connecting shafts 306. The outer ends of the two connecting shafts 306 are fixedly connected to a first sprocket 307. The outer shaft ends of the two walking wheels 302 are fixedly connected to a second sprocket 308. A first chain 309 is connected between the first sprocket 307 and the second sprocket 308. The inner ends of the two connecting shafts 306 are fixedly connected to a first bevel gear 3010. The walking frame 301 has two symmetrically connected and fixedly connected connecting plates 3011. A transmission rod 3012 is rotatably connected between the two connecting plates 3011. Two second bevel gears 3013 are fixedly connected to the transmission rod 3012 and respectively mesh with the first bevel gear 3010. A first waterproof motor 3014 is fixedly connected to the outer wall of one of the connecting plates 3011. The drive end of the first waterproof motor 3014 passes through the connecting plate 3011 and is fixedly connected to the shaft end of the transmission rod 3012.

[0026] The first waterproof motor 3014 drives the transmission rod 3012 to rotate. The second bevel gear 3013 on the transmission rod 3012 meshes with the first bevel gear 3010 at the inner end of the connecting shaft 306, thereby driving the connecting shaft 306 to rotate. The rotation of the connecting shaft 306 drives the first sprocket 307 to rotate synchronously. The first sprocket 307 drives the second sprocket 308 through the first chain 309, ultimately driving the walking wheel 302 to rotate, and driving the track 303 to walk on the seabed surface.

[0027] As shown in Figures 1 and 3, the vertical clamping assembly 7 includes two first mounting plates 701 fixed on the rear sidewalls of the first mounting frame 4 and the second mounting frame 5, respectively. A first screw 702 is rotatably connected between the two first mounting plates 701. A second waterproof motor 703 is fixedly connected to the upper first mounting plate 701. The drive end of the second waterproof motor 703 passes through the first mounting plate 701 and is fixedly connected to the shaft end of the first screw 702. A first moving opening is provided on the sidewalls of the first mounting frame 4 and the second mounting frame 5, and a first moving seat 704 is slidably connected in the first moving opening. The outer end of the first moving seat 704 is threadedly connected to the first screw 702. A first guide rod 705 is slidably connected in the first moving seat 704. The two ends of the first guide rod 705 are fixedly connected to the first mounting plate 701, respectively. A moving horizontal roller 706 is rotatably connected to the inner end of the first moving seat 704.

[0028] The second waterproof motor 703 drives the first screw 702 to rotate, causing the first movable seat 704 to slide up and down along the first guide rod 705. The movable horizontal roller 706 at the inner end of the first movable seat 704 rises and falls synchronously with the movable seat, thereby adjusting the distance between the movable horizontal roller 706 and the fixed horizontal roller 6, realizing the vertical clamping or loosening of the cable. The first guide rod 705 ensures that the first movable seat 704 moves smoothly without deviation, ensuring the parallelism between the movable horizontal roller 706 and the fixed horizontal roller 6, and avoiding cable clamping deformation.

[0029] As shown in Figures 1, 3, and 4, the lateral clamping assembly 9 includes two second mounting plates 901 fixed to the upper surfaces of the first mounting frame 4 and the second mounting frame 5, respectively. A second screw 902 is rotatably connected between the two second mounting plates 901. A third waterproof motor 903 is fixedly connected to the outer second mounting plate 901. The drive end of the third waterproof motor 903 passes through the second mounting plate 901 and is fixedly connected to the shaft end of the second screw 902. A second moving opening is provided on the upper surfaces of the first mounting frame 4 and the second mounting frame 5, and a second moving seat 904 is slidably connected in each of the second moving openings. A second guide rod 905 is slidably connected in the second moving seat 904. The two ends of the second guide rod 905 are fixedly connected to the second mounting plate 901, respectively. A moving vertical roller 906 is rotatably connected to the lower surface of the second moving seat 904.

[0030] The third waterproof motor 903 drives the second screw 902 to rotate, causing the second movable seat 904 to slide horizontally along the second guide rod 905; the movable vertical roller 906 at the lower end of the second movable seat 904 moves synchronously with the movable seat, adjusting the distance between the movable vertical roller 906 and the fixed vertical roller 8 to achieve lateral clamping or loosening of the cable. The second guide rod 905 ensures that the second movable seat 904 moves smoothly, ensuring the parallelism between the movable vertical roller 906 and the fixed vertical roller 8, and preventing lateral deviation of the cable.

[0031] As shown in Figures 1, 3, 7, and 8, the laying assembly 10 includes two symmetrical support plates 1001 fixed to the upper surface of the vehicle body 1. A first guide seat 1002 is rotatably connected between the two support plates 1001. A first ring 1003 is slidably connected to the first guide seat 1002. A rotating seat 1004 is fixedly connected to the outer sidewall of each of the two support plates 1001. A support arm 1005 is rotatably connected to the rotating seat 1004. A second guide seat 1006 is rotatably connected between the bottom ends of the support arms 1005. A second ring 1007 is slidably connected to the second guide seat 1006. A mating post 1008 is fixedly connected to the outer sidewall of the top wall of each support arm 1005. A movable head 1009 is rotatably connected to the mating post 1008. A telescopic extension is provided on the lower side of the movable head 1009. The driving end of the telescopic cylinder 1010 is fixedly connected to the bottom end of the movable head 1009. The bottom end of the telescopic cylinder 1010 is rotatably connected to the base 1011, which is fixedly connected to the upper end face of the vehicle body 1. A following rod 1012 is rotatably connected to the outer wall of the first ring 1003. The top end of the following rod 1012 is hinged to the second movable seat 904 on the second mounting frame 5 by a pin. The following rod 1012 is provided with a telescopic joint (not shown in the figure). When the telescopic cylinder 1010 drives the support arm 1005 to change the angle of the first guide seat 1002, the following rod 1012 can adaptively extend or deflect, ensuring that while adjusting the laying angle, the first ring 1003 can still be laterally centered by driving the second movable seat 904.

[0032] When the telescopic cylinder 1010 extends or retracts, it drives the movable head 1009 to rotate, thereby causing the support arm 1005 to rotate around the rotating seat 1004, adjusting the lowering angle and depth of the second guide seat 1006 to adapt to changes in seabed topography. The first guide seat 1002 and the second guide seat 1006 facilitate the guiding and laying of cables, ensuring the accuracy of cable laying.

[0033] As shown in Figures 1, 3, 7 and 8, a first limiting sleeve 1013 is fixedly connected to the outer wall of the first ring 1003, and a second limiting sleeve 1014 is fixedly connected to the outer wall of the second ring 1007. A linkage plate 1015 is provided between the first limiting sleeve 1013 and the second limiting sleeve 1014 and the first ring 1003 and the second ring 1007. The upper and lower ends of the linkage plate 1015 are rotatably connected to the first guide seat 1002 and the second guide seat 1006, respectively.

[0034] The first ring 1003 is linked to the second movable seat 904 via the follower rod 1012. When the lateral clamping assembly 9 is activated, the first ring 1003 moves synchronously with the second movable seat 904, which facilitates the guiding and laying of cables of different sizes. The first limiting sleeve 1013 and the second limiting sleeve 1014 maintain the coaxiality of the first guide seat 1002 and the second guide seat 1006, preventing the cable from twisting during the guiding process, facilitating the guiding and laying of cables of different sizes, and ensuring the accuracy of cable laying.

[0035] As shown in Figures 1, 3, 7 and 8, the centers of the first guide seat 1002, the first ring 1003 and the rotating seat 1004 are on the same central axis as the top center of the linkage plate 1015.

[0036] As shown in Figures 1, 2, 3 and 4, the outer end of the drive shaft 12 passes through the side wall of the second mounting frame 5 and is fixedly connected to the third sprocket 14. The third sprocket 14 is connected to the fourth sprocket 16 through the second chain 15. An extension shaft 17 is fixedly connected to the center of the fourth sprocket 16, and the end of the extension shaft 17 is fixedly connected to its inner end near the shaft end of the traveling wheel 302.

[0037] When the traveling wheel 302 rotates, it drives the fourth sprocket 16 to rotate through the extension shaft 17. The fourth sprocket 16 drives the third sprocket 14 through the second chain 15, which drives the transmission shaft 12 and the driving gear 13 to rotate. The driving gear 13 meshes with the driven gear 11, thereby driving the fixed horizontal roller 6 in the second mounting frame 5 to rotate.

[0038] As shown in Figures 1 and 2, the end of the fixed horizontal roller 6 away from the driven gear 11 passes through the first mounting frame 4 and the second mounting frame 5 respectively and is fixedly connected to the third bevel gear 18. Connecting ears 19 are fixedly connected to the outer walls of the first mounting frame 4 and the second mounting frame 5 respectively. Connecting rods 20 are rotatably connected between the connecting ears 19. Two fourth bevel gears 21 are fixedly connected to the connecting rods 20 respectively and mesh with the third bevel gear 18, so that the power input from the drive shaft 12 can be synchronously transmitted to the fixed horizontal roller 6 in the first mounting frame 4 through the connecting rods 20.

[0039] The rotation of the fixed horizontal roller 6 drives the third bevel gear 18 connected to it to rotate synchronously. The third bevel gear 18 drives the fourth bevel gear 21 and the connecting rod 20 to rotate synchronously. The rotation of the connecting rod 20 then mobilizes another fourth bevel gear 21 to rotate synchronously, which in turn drives another third bevel gear 18 and the fixed horizontal roller 6 to rotate synchronously, thus facilitating the transport of cables.

[0040] Specifically, when using this submarine cable construction equipment: first, pass one end of the cable to be laid sequentially through the clamping areas of the first mounting frame 4 and the second mounting frame 5, then through the space between the first guide seat 1002 and the first ring 1003, and the space between the second guide seat 1006 and the second ring 1007; finely adjust the second waterproof motor 703 and the third waterproof motor 903 through the control system, so that the moving horizontal roller 706 presses the cable downward and the moving vertical roller 906 clamps the cable inward, and adjust the telescopic cylinder. The telescopic cylinder 1010's extension range causes the movable head 1009 to rotate around the mating column 1008, which in turn drives the support arm 1005 to rotate around the rotating seat 1004, changing the lowering angle and depth of the second guide seat 1006 to ensure the cable is always laid close to the seabed surface. Then, the first waterproof motor 3014 drives the transmission rod 3012 to rotate, and the second bevel gear 3013 on the transmission rod 3012 meshes with the first bevel gear 3010 at the inner end of the connecting shaft 306, thereby driving... The rotating connecting shaft 306 drives the first sprocket 307 to rotate synchronously. The first sprocket 307 drives the second sprocket 308 through the first chain 309, which in turn drives the traveling wheel 302 to rotate, causing the track 303 to travel along the seabed surface. The rotation of the traveling wheel 302 is transmitted to the fourth sprocket 16 through the extension shaft 17. The fourth sprocket 16 drives the third sprocket 14 to rotate through the second chain 15, which in turn drives the transmission shaft 12 and the drive gear 13 to rotate. The drive gear 13 meshes with the driven gear 11, which drives the fixed horizontal roller 6 in the second mounting frame 5 to rotate. The fixed horizontal roller 6 cooperates with the moving horizontal roller 706 to realize the cable transport. At the same time, the rotation of the fixed horizontal roller 6 in the second mounting frame 5 is transmitted to the fourth bevel gear 21 through the third bevel gear 18, which drives the connecting rod 20 to rotate, which in turn drives the fixed horizontal roller 6 in the first mounting frame 4 to rotate synchronously, realizing the synchronous transport of cables in the two mounting frames, ensuring that the traveling speed and the cable transport speed are accurately matched, and avoiding cable pulling or slack accumulation.
