[0004] To achieve the above objectives, this utility model provides the following technical solution: an underwater cable-laying support for a cable-laying vessel, comprising a support platform and a U-shaped frame. The top of the support platform is provided with a U-shaped frame, and a transverse lead screw is provided at the middle position of the inner top of the U-shaped frame via a bearing seat. The lead screw has multiple sets of bidirectional threaded sections evenly distributed on it, and each threaded section of the lead screw is threadedly connected to a vertical clamping plate. The middle position of the inner side of each clamping plate is arc-shaped, and a buffer pad is provided in the arc-shaped groove on the inner side of each clamping plate. An insert block is provided at the middle position of the bottom of the U-shaped frame, and the insert block corresponds to the top of the support platform. A slot is provided in the middle of the frame, and all the plugs are inserted into the support platform through the slot. A spring groove is provided in the middle of both sides of the plug in the support platform, and a spring is provided in each spring groove. A fixing block is provided at the other end of each spring, and a fixing groove is provided in each plug corresponding to the fixing block.

In use, the U-shaped frame can be easily assembled and disassembled, and different U-shaped frames can be easily replaced.

[0005] As a further technical solution of this utility model, the front and back sides of the inner bottom end of the U-shaped frame are provided with sliding rods, and the clamping plates corresponding to the sliding rods are provided with through grooves. The clamping plates are slidably connected to the sliding rods through the through grooves, so that the clamping plates can slide on the sliding rods when they move, making their movement more stable.

[0006] As a further technical solution of this utility model, the end of the fixing block away from the spring is inclined, and the middle position of the fixing block near the spring is provided with an annular magnetic strip, and the middle position of the fixing block is provided with a threaded groove, so that the inclined end of the fixing block is easy to squeeze during insertion, and the annular magnetic strip at the other end can be magnetically attracted to the threaded block.

[0007] As a further technical solution of this utility model, a threaded rod is provided in the middle position of the spring groove, and a metal threaded block is connected to the threaded rod by thread. The other end of the threaded rod extends into the threaded groove by thread, so that when the threaded rod rotates in the spring groove, it can drive the threaded block to move towards the fixed block, so that it can limit the fixed block.

[0008] As a further technical solution of this utility model, the bottom of the support platform is provided with downward-sloping support frames on all four sides, and a second lead screw is provided in the middle of the bottom of the support platform. A lowering plate is connected to the second lead screw by thread, and an insertion rod is provided in the middle of the bottom of the lowering plate. The support platform is initially fixed by the support frames at the bottom. Then the second lead screw can drive the lowering plate to move down, and the lowering plate can drive the insertion rod to move down and insert it into the mud at the bottom of the water for secondary fixation, which can prevent it from shifting.

[0009] As a further technical solution of this utility model, a motor slot is provided at the middle position of the bottom end of the support platform, and a second motor is provided in the motor slot of the support platform. The output end of the second motor extends to the bottom of the support platform through a bearing and a coupling and is connected to the second lead screw, so that the motor slot supports and protects the second motor, and the output end of the second motor can drive the second lead screw to rotate through the coupling.

After the rotation is completed, the sealing plug can be inserted into the circular groove for protection.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By placing multiple sets of cables inside the opposing clamping plates, the bidirectional threaded section on the lead screw can drive the clamping plates to move relative to each other, which can stably clamp multiple sets of cables in the arc groove inside the clamping plates. Multiple sets of cables can be clamped at the same time, which can improve the cable laying speed and facilitate the clamping of cables of different thicknesses. By inserting the plug at the bottom of the U-shaped frame into the support platform, the plug can squeeze the fixing block and compress the spring during insertion. After the plug is inserted into place, the fixing block is inserted into the fixing groove in the plug under the elastic force of the spring, which can fix the connection.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5An embodiment of this utility model provides an underwater cable laying support for a cable laying vessel, comprising a support platform 1 and a U-shaped frame 2. The top of the support platform 1 is provided with the U-shaped frame 2, and a horizontal lead screw 3 is provided at the middle position of the top inner side of the U-shaped frame 2 through a bearing seat. A motor cover 5 is provided on the outer surface of the U-shaped frame 2 at one end of the lead screw 3, and a motor 12 is provided inside the motor cover 5. The output end of the motor 12 extends to the inner side of the U-shaped frame 2 and is connected to the lead screw 3 through a bearing and a coupling. Multiple sets of bidirectional threaded sections are evenly provided on the lead screw 3, and vertical clamping plates 4 are threadedly connected to the threaded sections of the lead screw 3. The middle position of the inner side of the clamping plates 4 is arc-shaped, and buffer pads 6 are provided in the arc-shaped grooves on the inner side of the clamping plates 4. Slide rods 7 are provided on the front and back sides of the bottom inner side of the U-shaped frame 2, and through grooves are provided on the clamping plates 4 corresponding to the slide rods 7. The clamping plates 4 are slidably connected to the slide rods 7 through the through grooves. Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, multiple sets of cables are placed in the arc-shaped groove on the inner side of the clamping plate 4. Then, the motor 12 can be started to drive the lead screw 3 to rotate. The bidirectional threaded section on the lead screw 3 can drive the clamping plate 4 to move relative to each other. At the same time, the bottom end of the clamping plate 4 can slide relative to each other on the slide rod 7. Multiple sets of cables can be stably clamped in the arc-shaped groove on the inner side of the clamping plate 4. The buffer pad 6 can prevent the cables from being damaged during the clamping process. Multiple sets of cables can be clamped at the same time, which can improve the cable laying speed and facilitate the clamping of cables of different thicknesses. A plug 13 is provided at the middle position of the bottom of the U-shaped frame 2, and a slot is provided at the middle position of the top of the support platform 1 corresponding to the plug 13. The plug 13 is inserted into the support platform 1 through the slot. A spring groove 20 is provided at the middle position of both sides of the plug 13 in the support platform 1, and a spring 21 is provided in the spring groove 20. A fixing block 15 is provided at the other end of the spring 21, and a fixing groove is provided in the plug 13 corresponding to the fixing block 15. The fixing block 15 is inserted into the plug 13 through the fixing groove. Specifically, such as Figure 2 and Figure 5 As shown, when laying cables, the workers can insert the plug 13 at the bottom of the U-shaped frame 2 into the slot at the top of the support platform 1. When it is inserted, it can squeeze the fixing block 15, so that the fixing block 15 compresses the spring 21 in the spring groove 20. When the plug 13 is inserted into place, the fixing block 15 is inserted into the fixing groove in the plug 13 under the elastic force of the spring 21. This can achieve a stable connection between the U-shaped frame 2 and the support platform 1, and can facilitate the installation and disassembly of the U-shaped frame 2. It also allows the workers to flexibly replace different U-shaped frames 2 according to actual needs to support and clamp the cables. The end of the fixing block 15 away from the spring 21 is beveled, and the middle position of the fixing block 15 near the spring 21 is provided with an annular magnetic strip. The middle position of the fixing block 15 is provided with a threaded groove 22. The middle position of the spring groove 20 is provided with a threaded rod 19. The threaded rod 19 is connected to a metal threaded block 23 by threads. The other end of the threaded rod 19 extends into the threaded groove 22 by threads. The two sides of the support platform 1 are provided with circular grooves 17 corresponding to the positions of the threaded rods 19. The middle position of the circular grooves 17 is provided with a turntable 18. The circular grooves 17 on the outer side of the turntable 18 are provided with sealing plugs 16. The rotating rods on the inner side of the turntable 18 extend into the spring groove 20 and are connected to the threaded rods 19 by bearings and couplings. Specifically, such as Figure 2 , Figure 4 and Figure 5 As shown, the operator rotates the turntable 18 to drive the threaded rod 19 to rotate, which in turn drives the threaded block 23 to move. This allows the threaded block 23 to press and limit one end of the fixed block 15, and the threaded block 23 to be magnetically fixed to the fixed block 15 via the annular magnetic strip, preventing the fixed block 15 from shifting. After the limiting and fixing is completed, the sealing plug 16 can be inserted into the circular groove 17 to prevent the circular groove 17 from being directly exposed. When disassembly is required, the sealing plug 16 can be removed, and the turntable 18 can be rotated in the opposite direction to end the limiting effect and move the fixed block 15 away from the fixing groove for easy disassembly. The bottom of the support platform 1 is provided with downward-sloping support frames 8 on all four sides, and a screw rod 11 is provided in the middle of the bottom of the support platform 1. A lowering plate 9 is connected to the screw rod 11 by thread, and a plug rod 10 is provided in the middle of the bottom of the lowering plate 9. A motor slot is provided in the middle of the bottom of the support platform 1, and a motor 14 is provided in the motor slot of the support platform 1. The output end of the motor 14 extends to the bottom of the support platform 1 and is connected to the screw rod 11 by bearings and couplings. Specifically, such as Figure 1 and Figure 2 As shown, the bottom of the support platform 1 is supported by the inclined support frame 8 contacting the plane. Then, the motor 14 is started to drive the lead screw 11 to rotate. The rotation of the lead screw 11 drives the lower plate 9 to move downward. The downward movement of the lower plate 9 drives the insertion rod 10 to move downward, so that the insertion rod 10 is inserted into the mud at the bottom of the water, providing stable support for the support platform 1 and preventing the support platform 1 from shifting during the cable laying process, which would affect the cable laying effect.

[0016] Working principle: During use, when laying cables, the worker can insert the plug 13 at the bottom of the U-shaped frame 2 into the slot at the top of the support platform 1. During insertion, it presses against the fixing block 15, causing the fixing block 15 to compress the spring 21 within the spring groove 20. Once the plug 13 is in place, the fixing block 15, under the elastic force of the spring 21, is inserted into the fixing groove within the plug 13, achieving a stable connection between the U-shaped frame 2 and the support platform 1. This allows for convenient installation and disassembly of the U-shaped frame 2, enabling workers to flexibly replace different U-shaped frames 2 according to actual needs. The cable is supported and clamped. After installation, the turntable 18 can be rotated to drive the threaded rod 19 to rotate, causing the threaded rod 19 to move the threaded block 23. This allows the threaded block 23 to press and limit one end of the fixed block 15, and the threaded block 23 is magnetically fixed to the fixed block 15 through the annular magnetic strip, preventing the fixed block 15 from shifting. After the limiting and fixing is in place, the sealing plug 16 can be inserted into the circular groove 17 to prevent the circular groove 17 from being directly exposed. When disassembly is required, the sealing plug 16 can be removed, and the turntable 18 can be rotated in the opposite direction to allow the limiting... The positioning effect ends, and it moves the fixing block 15 away from the fixing groove for easy disassembly. When cable laying is required, multiple sets of cables are placed in the arc-shaped groove on the inner side of the clamping plate 4. Then, the motor 12 can be started to drive the lead screw 3 to rotate, which can cause the bidirectional threaded section on the lead screw 3 to move the clamping plate 4 relative to each other. At the same time, the bottom end of the clamping plate 4 can slide relative to each other on the slide rod 7, which can stably clamp multiple sets of cables in the arc-shaped groove on the inner side of the clamping plate 4. The buffer pad 6 can prevent the cables from being damaged during the clamping process. Multiple sets of cables can be clamped at the same time, which can improve the efficiency of cable laying. The cable is lowered at a certain speed and can be easily clamped with cables of different thicknesses. After the cable is clamped, it is slowly lowered into the water according to the preset path and depth. When it descends to the plane, the bottom of the support platform 1 can be supported by the inclined support frame 8. Then, the motor 2 14 is started to drive the lead screw 2 11 to rotate. The rotation of the lead screw 2 11 drives the lower plate 9 to move downward. The downward movement of the lower plate 9 drives the insertion rod 10 to move downward, so that the insertion rod 10 is inserted into the mud at the bottom of the water, providing stable support for the support platform 1 and preventing the support platform 1 from shifting during the cable laying process, which would affect the cable laying effect.

[0017] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
