Technical Field
[0001] This utility model relates to the field of submarine cable laying technology, specifically a submarine cable laying slide plow blade for a cable laying vessel. Background Technology
[0002] The cable laying plow is a primary cable-laying device on a cable-laying vessel. It is a symmetrical, multi-bladed plow used for digging trenches in shallow seas. It can be towed along the seabed, plowing trenches 0.7-1 meters deep for cable laying. A cable guide cage is used in conjunction with the plow to prevent signal cables from becoming entangled with the cable-laying steel cables.
[0003] Currently, submarine cables and optical fibers are mainly laid using a method of simultaneous laying and burying with a cable-burying plow. This method requires equipment such as gantry cranes, winches, high-pressure water hoses, and traction ropes for construction, and submarine cable laying requires specialized vessels, resulting in high costs. For near-shore submarine cable laying projects with short distances, the above-mentioned traditional submarine cable laying technology is too costly and urgently needs to be developed.
