Description

Technical Field

[0001] This utility model relates to the field of submarine cable laying technology, specifically a submarine cable laying and burial device. Background Technology

[0002] Compared to laying cables on land, laying cables on the seabed offers several advantages. First, seabed laying is relatively cheaper and faster, and is not limited by land-based obstacles such as mountains, rivers, or roads. Second, seawater prevents interference from external optical and magnetic waves, improving the communication quality of the fiber optic cable, reducing noise, and making the latency virtually imperceptible to users. Furthermore, submarine cables are less susceptible to interference and damage from human activities. Existing submarine cable laying and burial equipment is generally sufficient for daily use, but some shortcomings still require improvement.

[0003] Existing submarine cable laying and burial devices typically use water pipes to create a groove on the seabed surface. The cable is then placed into the groove, causing it to fall into the pre-buried area. However, due to the different cable types being laid, these cables can shift within the groove, preventing them from fitting properly and leaving them exposed. This can easily lead to cable damage. Therefore, we propose a submarine cable laying and burial device to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a device for laying and burying submarine cables to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a submarine cable laying and burial device, comprising a frame, a submersible pump housed within the frame, a water pipe on the left side of the submersible pump, a plow blade on the right side of the frame, an insertion groove formed in the frame between the submersible pump and the plow blade, a positioning component on the insertion groove, the positioning component comprising a movable compartment mounted on the left side of the frame of the insertion groove, a bearing mounted on the inner wall of the movable compartment, a double-ended lead screw fixedly connected to the bearing, a brake disc on the front end surface of the double-ended lead screw, two sets of transmission blocks threadedly connected to the double-ended lead screw, a connecting plate on the right side of each transmission block, a clamping plate at the bottom of each connecting plate, and a guide plate on the inner wall of the insertion groove in the middle of the two sets of clamping plates.

[0006] As a further preferred embodiment of this technical solution, the connecting plate can also be connected to the clamping plate via a connecting assembly. The connecting assembly includes a fixed seat disposed on the outer wall of the clamping plate on the side opposite to the guide plate. A rotating rod is rotatably disposed within each fixed seat, and a torsion spring is wound around each rotating rod. A pressing plate is disposed on the outer wall of the rotating rod below the connecting plate. A limiting groove is formed in each connecting plate, and the rotating rod is slidably connected to the limiting groove. A limiting block is disposed on the outer wall of the rotating rod above the connecting plate.

[0007] As a further preferred embodiment of this technical solution, both the clamping plate and the guide plate are L-shaped, and both the clamping plate and the guide plate have arc-shaped grooves with the same curvature as the outer wall of the submarine cable.

[0008] As a further preferred embodiment of this technical solution, the surface of the brake disc is provided with anti-slip texture, and the surface of the brake disc may also be covered with an anti-slip rubber sleeve.

[0009] As a further preferred embodiment of this technical solution, the limiting block is rectangular in shape, and two sets of the limiting blocks are provided, with both sets of the limiting blocks and the limiting grooves being staggered.

[0012] This utility model provides a device for laying and burying submarine cables, which has the following advantages: 1. This utility model uses a positioning component installed on the insertion groove. By placing the submarine cable on the guide plate and then rotating the brake disc, the brake disc drives the double-ended lead screw to rotate on the bearing. The rotating double-ended lead screw synchronously drives two sets of transmission blocks, causing the two sets of transmission blocks to move within the movable chamber and converge towards the center of the double-ended lead screw. While the transmission blocks are moving, they drive two sets of clamping plates to move synchronously through the connecting plate until the two sets of clamping plates are close to the outer wall of the submarine cable. This achieves the purpose of positioning submarine cables of different models, so that the submarine cable can be buried in the groove and prevent the submarine cable from being partially exposed, which could easily lead to damage.

[0013] 2. This utility model, through the connecting component set between the connecting plate and the clamping plate, can rotate the rotating rod, causing the rotating rod to rotate within the fixed seat and drive the torsion spring to twist, so that the rotating rod drives the limiting block to align with the limiting groove. Then, by sliding the rotating rod and the limiting block out of the limiting groove, the clamping plate can be disassembled, so that the staff can replace the clamping plate and clean the attached objects on the clamping plate before continuing to use it.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] This utility model provides a technical solution: such as Figures 1 to 6As shown, in this embodiment, the submarine cable laying and burial device includes a frame 1, a submersible pump 2 is installed inside the frame 1, a water pipe 3 is installed on the left side of the submersible pump 2, a plow blade 4 is installed on the right side of the frame 1, an insertion groove 5 is opened in the frame 1 between the submersible pump 2 and the plow blade 4, a positioning component 6 is installed on the insertion groove 5, the positioning component 6 includes a movable compartment 61 installed on the left side of the frame 1 of the insertion groove 5, a bearing 62 is installed on the inner wall of the movable compartment 61, a double-ended lead screw 63 is fixedly connected to the bearing 62, a brake disc 64 is installed on the front end surface of the double-ended lead screw 63, two sets of transmission blocks 65 are threadedly connected to the double-ended lead screw 63, a connecting plate 66 is installed on the right side of each transmission block 65, a clamping plate 67 is installed at the bottom of each connecting plate 66, and a guide plate 68 is installed on the inner wall of the insertion groove 5 in the middle of the two sets of clamping plates 67.

[0018] By using the positioning component 6 installed on the insertion groove 5, the submarine cable is placed on the guide plate 68, and then the brake disc 64 is rotated, causing the double-ended lead screw 63 to rotate on the bearing 62. The rotating double-ended lead screw 63 synchronously drives two sets of transmission blocks 65, causing the two sets of transmission blocks 65 to move within the movable chamber 61 and converge towards the center of the double-ended lead screw 63. While the transmission blocks 65 are moving, they drive two sets of clamping plates 67 to move synchronously through the connecting plate 66 until the two sets of clamping plates 67 are close to the outer wall of the submarine cable. This achieves the purpose of positioning submarine cables of different models, so that the submarine cable can be buried in the groove, preventing the submarine cable from being partially exposed and thus easily damaged.

[0019] In other embodiments, the connecting plate 66 can also be connected to the clamping plate 67 via the connecting assembly 7. The connecting assembly 7 includes a fixed seat 71 disposed on the outer wall of the clamping plate 67 on the side opposite to the guide plate 68. A rotating rod 72 is rotatably disposed in the fixed seat 71. A torsion spring 73 is wound around the rotating rod 72. A pressing plate 74 is disposed on the outer wall of the rotating rod 72 below the connecting plate 66. A limiting groove 75 is opened in the connecting plate 66. The rotating rod 72 is slidably connected to the limiting groove 75. A limiting block 76 is disposed on the outer wall of the rotating rod 72 above the connecting plate 66. By using the connecting assembly 7 between the connecting plate 66 and the clamping plate 67, the rotating rod 72 can be rotated, causing the rotating rod 72 to rotate within the fixed base 71 and drive the torsion spring 73 to twist. This causes the rotating rod 72 to align the limiting block 76 with the limiting groove 75. By sliding the rotating rod 72 and the limiting block 76 out of the limiting groove 75, the clamping plate 67 can be disassembled, making it easier for workers to replace the clamping plate 67 and clean any adhering substances on it before reuse.

[0020] In other embodiments, both the clamping plate 67 and the guide plate 68 have arc-shaped grooves with an arcuate curvature equal to that of the outer wall of the submarine cable. This design allows the outer wall of the submarine cable to be the same as that of the clamping plate 67 and the guide plate 68, thereby increasing the contact area between the guide plate 68 and the clamping plate 67 and the submarine cable. This prevents the submarine cable from shifting within the guide plate 68, which could lead to a poorer burial effect and make the exposed submarine cable more susceptible to damage.

[0021] In other embodiments, the surface of the brake disc 64 is provided with anti-slip texture, and the surface of the brake disc 64 may also be covered with an anti-slip rubber sleeve; This design achieves a double anti-slip effect on the brake disc 64, preventing seaweed from adhering to the surface of the brake disc 64 and causing slippage during use.

[0022] In other embodiments, the limiting block 76 is rectangular in shape, and two sets of limiting blocks 76 are provided. Both sets of limiting blocks 76 and the limiting groove 75 are staggered. This design allows workers to easily rotate the lever 72 within the fixed base 71 using the limit block 76, preventing slippage when rotating the limit block 76 and further improving the stability of the limit block 76 during use.

[0023] In other embodiments, a rubber ring is provided on the side surface of the extrusion plate 74 facing the connecting plate 66, and the rubber ring has the same shape as the extrusion plate 74. This design prevents direct contact between the extrusion plate 74 and the connecting plate 66, thereby reducing frictional damage that occurs when the extrusion plate 74 and the connecting plate 66 come into contact with each other.

[0024] In other embodiments, the inner diameter of the torsion spring 73 is equal to the outer diameter of the rotating rod 72, the inner wall of the torsion spring 73 is in contact with the outer wall of the rotating rod 72, and both ends of the torsion spring 73 are welded to the inner wall of the fixed seat 71. This design prevents the torsion spring 73 from shifting on the rotating rod 72, which would weaken the restoring force of the torsion spring 73 and make it difficult to drive the rotating rod 72 to return to its original position.

[0025] This utility model provides a device for laying and burying submarine cables, the specific working principle of which is as follows: In use, the submarine cable is first placed into the insertion groove 5 and aligned with the guide plate 68. Then, by rotating the brake disc 64, the double-ended lead screw 63 rotates on the bearing 62, and the rotating double-ended lead screw 63 synchronously drives the two sets of transmission blocks 65. The two sets of transmission blocks 65 move within the movable chamber 61 and converge towards the center of the double-ended lead screw 63. While the transmission blocks 65 are moving, they drive the two sets of clamping plates 67 to move synchronously through the connecting plate 66 until the two sets of clamping plates 67 are almost in contact with the outer wall of the submarine cable. At this point, the laying vessel towing frame 1 moves the frame 1, and the water pipe 3 drives the submersible pump 2 to flush the seabed, creating a groove. Under the action of gravity, the submarine cable slides into the groove through the guide plate 68 and the clamping plate 67. The frame 1 then drives the plow blade 4, which pushes the mud and sand to pre-bury the groove, thereby achieving the purpose of burying the submarine cable.
