Description

Technical Field

[0001] This utility model relates to the technical field of submarine cable laying, and in particular to a lifting device for submarine cable laying. Background Technology

[0002] Submarine cable laying is a complex engineering project that safely lays submarine cables to the seabed, requiring precise operations that combine the marine environment, cable characteristics, and technical equipment. Before laying, a detailed survey must be conducted, using sonar to map the seabed topography, avoiding obstacles such as coral reefs and trenches, and assessing the impact of ocean currents, tides, and geological activity to determine the optimal route. During construction, specialized cable-laying vessels play a crucial role. Onboard laying equipment, such as tension control systems, releases the cable with constant tension, preventing excessive bending and damage to the internal structure. For example, when laying transoceanic communication cables, fiber optic attenuation testing must be conducted simultaneously to ensure signal transmission quality; while laying submarine power cables requires controlled burial depth, typically 0.5-3 meters below the seabed, to prevent damage from fishing boat anchors or seawater erosion. Laying methods are flexibly adjusted according to different marine environments: in shallow waters, plow-type burial machines can be used to bury the cable into the seabed, while in deep waters, remotely operated underwater vehicles (ROVs) are used for positioning and fixation. Furthermore, the laying process requires real-time monitoring of cable temperature, tension, and other parameters, and after completion, withstand voltage tests and signal verification are necessary. With the development of offshore wind power, submarine cable laying also needs to be coordinated with wind turbine foundation construction, such as adopting the "lay first, then bury" process to ensure the stable connection of the offshore energy network.

[0003] During submarine cable laying, the cable is transported from the dock to the laying vessel by crane for splicing, and then transported by the vessel to the designated sea area for laying. Currently, submarine cable laying vessels are generally not equipped with offshore splicing devices. Usually, two laying vessels approach each other and then the cable is transported by guide wheels. When the position changes, the guide wheels need to be moved back and forth, making the cable transport between the two laying vessels less than ideal.

[0004] Currently, no effective solution has been proposed for the problems of unsatisfactory transmission of submarine cables between ships and the need to move the guide wheels back and forth in related technologies. Utility Model Content

Furthermore, by utilizing the cooperation between the telescopic unit and the telescopic drive unit, the telescopic unit can achieve dynamic length adjustment under the action of the telescopic drive unit. When the distance between the two ships changes due to tides and ocean currents, the telescopic unit automatically extends or shortens, adapting to the position between the two laying vessels according to usage requirements, thus ensuring the reliability of cable delivery.
