Description

Technical Field

[0001] The utility model relates to the technical field of submarine cable laying equipment, in particular to a traction laying device and a traction system for submarine cables. Background Art

[0002] A submarine cable is a cable wrapped with insulating materials and laid on the seabed for telecommunication transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Submarine communication cables are mainly used for communication services, which are expensive but highly confidential. Submarine power cables are mainly used for underwater transmission of high-power electrical energy, which is equivalent to the function of underground power cables, except for the application scenarios and laying methods.

[0003] When laying a submarine cable, the submarine cable will be passed through a laying pipe. During the process, first, a diver checks the inlet of the laying pipe underwater, binds the traction steel wire rope reserved in the laying pipe with a thin rope, and the construction ship uses the thin rope to pull the traction steel wire rope out of the water, and then connects the steel wire rope with the cable head for subsequent construction operations.

[0004] During this process, in some operating waters, the underwater currents are strong, and the diver can only enter the water during slack tide, which affects the construction efficiency. Moreover, the effective working time of the diver underwater is short, and the decompression time required to ensure the health and safety of the diver will be longer. To ensure the safety of diving operations, each diving team needs to be equipped with multiple types of work, such as diving doctors, diving supervisors, and mechanics. In addition, a decompression chamber needs to be equipped as an emergency guarantee.

[0005] Currently, for the problems of underwater operations affecting construction efficiency and potential safety hazards during long-term underwater work in the related art, no effective solutions have been proposed. Content of the Utility Model
