Description

Technical Field

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

[0002] The submarine cable laying plough is a core piece of equipment for laying submarine cables. It is typically installed on laying vessels or specialized work platforms, resembling a robotic arm with a sharp shovel head, and is adaptable to various seabed terrains. During operation, the plough first precisely locates the laying path using a positioning system. The shovel head then cuts into the seabed sediment layer, creating a trench 0.5-3 meters deep (adjusted according to the marine environment). Simultaneously, the submarine cable is transported into the trench, and a compaction mechanism then levels the sediment to complete the burial, preventing damage from fishing boat anchors, marine organisms, or water currents. Equipped with pressure and depth sensors and a real-time monitoring module, the equipment can dynamically adjust operating parameters to adapt to different seabed types, including sandy and silty seabeds. It is a crucial piece of equipment for ensuring the stable laying of submarine communication and power transmission lines, and is widely used in transoceanic submarine cables, near-shore wind power submarine cables, and other projects.

[0003] In current submarine cable laying operations, the trenching chainsaw on a trailing suction hopper dredger is used for initial trenching and soil breaking, followed by the laying of the cable using a traditional burial plow (single shovel head structure), forming a segmented operation mode of "chainsaw initial crushing - burial plow laying". However, the traditional burial plow, relying solely on a single shovel head, cannot meet the operational needs after the initial crushing by the chainsaw. When facing dense seabeds such as silt or clay, the single shovel head cannot quickly break up the remaining clumps of soil after the initial crushing by the chainsaw, resulting in slow trenching speed.

[0004] Currently, no effective solution has been proposed for the problems of difficulty in secondary soil breaking and slow trenching after the initial chain sawing of submarine cable laying. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a burying plow for submarine cable laying, thereby solving the problems of difficulty in secondary soil breaking and slow trenching after the initial breaking of the submarine cable by the chainsaw.

[0031] In some embodiments, the drive unit further includes:

[0032] A fourth transmission element is movably disposed inside the housing element and connected to the driving end of the driving element, for rotating in the vertical direction under the action of the driving element;

[0033] The fifth transmission element is movably disposed inside the shell element and located below the fourth transmission element, and is connected to the crushing unit to drive the crushing unit to move;

The crushing unit works in conjunction with the main unit. The support structure of the main unit provides force support for the crushing unit, preventing the crushing unit from deforming or breaking under impact, while limiting the crushing range and ensuring that the trench shape is regular, laying a good foundation for submarine cable laying.

[0145] (I) Installation Operation

[0146] Connect and fix the main component 11 to the dredge arm (submarine cable support channel) on the dredge suction hopper.

[0147] (II) Laying operations

[0148] The submarine cable is introduced into the through slot element 14 through the submarine cable support channel, and then enters the guide element 21 through the through slot element 14.

[0149] The main component 11 is placed into the designated position (seabed) by the drag arm of the dredging vessel;

[0150] Start the trailing suction hopper dredger to carry out the laying operation;

[0151] During the process, the chainsaws set up on the suction hopper boat are used for initial trenching and soil breaking;

[0152] The drive element 42 is activated, causing it to drive the fourth transmission element 43 to rotate. The fourth transmission element 43, through the cooperation between the sixth transmission element 45 and the fifth transmission element 44, drives the first transmission element 31 to rotate around the third rotating element 46.

[0153] The first transmission element 31 drives the crushing element 34 to move through the cooperation between the second transmission element 32 and the third transmission element 33, thereby crushing the soil in the initial trench.

[0154] The advantage of this utility model is that the main unit brings about the integrated installation of various functional units of the burial plow and the basic support effect for seabed operations. It provides stable accommodation and fixed space for the guiding unit, crushing unit and driving unit, ensuring that each unit maintains a stable relative position in the complex seabed environment and avoiding misalignment of components due to water flow impact or soil resistance. Furthermore, the main unit works in conjunction with the crushing unit and the drive unit. The main unit provides rotational support for the crushing unit through a rotating structure, allowing the crushing unit to move stably along a preset trajectory. At the same time, it provides protection and fixation for the drive unit, preventing it from directly contacting seawater and silt, reducing the risk of corrosion and jamming, and ensuring long-term reliable operation of the equipment. The coordinated use of the guide unit, crushing unit, and drive unit brings about a secondary crushing effect on the seabed soil. Through the transmission components, it drives the crushing components to move, which can crush the clumps of soil remaining after the initial trenching by the chainsaw. It is especially suitable for dense seabeds such as silt and clay, solving the problem of low crushing efficiency of traditional single shovel heads and improving trenching speed. The crushing unit works in conjunction with the main unit. The support structure of the main unit provides force support for the crushing unit, preventing the crushing unit from deforming or breaking under impact, while limiting the crushing range and ensuring that the trench shape is regular, laying a good foundation for submarine cable laying.

[0155] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
