Technical Field

[0001] This utility model relates to the field of submarine cable salvage, specifically to a submarine cable salvage hook and anchor for offshore wind power. Background Technology

[0002] Submarine cable salvage refers to the process of recovering or repairing cables (including submarine optical cables and submarine power cables) that have sunk to the seabed. This process may be necessary for various reasons, such as the need to relocate submarine cables to facilitate municipal engineering projects, or the need to repair or replace submarine cables due to malfunctions.

[0003] Commonly used marine mooring for salvage primarily employs a simple three-pronged salvage anchor attached to the salvage line. However, existing three-pronged salvage anchors have a simple structure and lack a mechanism for securing and clamping the submarine cable, resulting in a low success rate for salvaging submarine cables. Therefore, those skilled in the art have developed a submarine cable salvage hook anchor for offshore wind power to address the problems mentioned in the background section. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a submarine cable salvage hook and anchor for offshore wind power, used to complete the salvage operation of damaged submarine cables.

[0022] Please see Figures 1-4This embodiment provides a retrieval hook and anchor for offshore wind power cables, including a crossbar 1. The upper end of the crossbar 1 has several threaded grooves 2. Several movable rings 3 are slidably connected to the outer surface of the crossbar 1. Fastening bolts 4 are installed inside the movable rings 3. A chain 5 is installed at the lower end of the movable rings 3. A fixed ring 6 is installed at the lower end of the chain 5. An anchor rod 7 is installed at the lower end of the fixed ring 6. Several anchor hooks 8 are installed on the lower part of the outer surface of the anchor rod 7. Matching holes 9 are opened inside the anchor hooks 8. A lifting mechanism 10 is installed inside the anchor rod 7. A lifting ring 15 is slidably connected to the outer surface of the anchor rod 7, and the lifting ring 15 is connected to the lifting mechanism 10. The lifting mechanism 10 includes a lifting hole 11 and a threaded rod 12. The lifting hole 11 is opened inside the anchor rod 7, and the threaded rod 12 is rotatably connected inside the lifting hole 11. A motor 13 is installed at the upper end of the threaded rod 12. A threaded sleeve 14 is fitted onto the outer surface of the threaded rod 12, and the threaded sleeve 14 is fixedly connected to the lifting ring 15. 5. Several arc-shaped limiting rods 16 are provided on the side, and the positions of the arc-shaped limiting rods 16 correspond to the positions of the mating holes 9. A rotating shaft 17 is installed on the end of the arc-shaped limiting rod 16 near the lifting ring 15. The two ends of the rotating shaft 17 are rotatably connected to the stop blocks, and the stop blocks are fixedly connected to the lifting ring 15. Torsion springs 18 are symmetrically sleeved on the outer surface of the rotating shaft 17. One end of the torsion spring 18 is fixedly connected to the stop block, and the other end of the torsion spring 18 is fixedly connected to the arc-shaped limiting rod 16. Several blocking blocks 19 are installed on the side of the lifting ring 15, and the blocking blocks 19 are located at the upper end of the arc-shaped limiting rod 16. Elastic mechanisms 21 are symmetrically installed at the lower end of the arc-shaped limiting rod 16. The elastic mechanism 21 includes a hollow block 22 and a slider 23. The slider 23 is slidably connected inside the hollow block 22. A solid block 25 is installed on the upper end of the slider 23, and the solid block 25 passes through the hollow block 22. A spring 24 is installed on the lower end of the slider 23. A clamping rod 20 is installed on the lower end of the two elastic mechanisms 21.

[0023] The working principle of this utility model is as follows: Multiple anchor rods 7 are installed on the crossbar 1 according to usage requirements. The moving ring 3 is pushed to adjust the distance between adjacent anchor rods 7. Then, the fastening bolts 4 are screwed into the threaded groove 2 to fix the position of the anchor rods 7. During the process of the anchor hook 8 hooking the submarine cable, the submarine cable will push the arc-shaped limiting rod 16 to rotate downwards around the rotating shaft 17 and retract. The torsion spring 18 is torsionally deformed. When the submarine cable is stuck in the anchor hook 8, the arc-shaped limiting rod 16 loses its limiting force. The torsion spring 18 pushes the arc-shaped limiting rod 16 to reset. Then, the control motor 13 drives the threaded rod 12 to rotate. 2. The threaded sleeve 14 drives the lifting ring 15 to descend, and the lifting ring 15 drives the arc-shaped limiting rod 16 to descend and press on the submarine cable. At the same time, the end of the arc-shaped limiting rod 16 passes through the mating hole 9, and the blocking block 19 provides a limiting force to the arc-shaped limiting rod 16, making the arc-shaped limiting rod 16 unable to rotate. The arc-shaped limiting rod 16 presses on the submarine cable, and the anchor hook 8 and the arc-shaped limiting rod 16 clamp the submarine cable, fixing its position, which is convenient for the submarine cable to be retrieved. At the same time, the spring 24 pushes the solid block 25, and the solid block 25 pushes the clamping rod 20 to abut against the submarine cable, improving the clamping stability of the submarine cable.
