Description

Technical Field

[0001] The utility model relates to the technical field of submarine cable laying, in particular to a protection mechanism for submarine cable laying. Background Art

[0002] Submarine cables are cables wrapped with insulating materials and laid on the seabed for telecommunication transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Modern submarine cables use optical fiber as material to transmit telephone and Internet signals. Usually, the laying of submarine cables requires the help of submarine cable construction ships. The submarine cable is wound on the cable drum on the surface of the construction ship. One end of the submarine cable is fixed on land. As the construction ship moves, the cable drum rotates to achieve the unwinding and laying of the submarine cable.

[0003] However, during the unwinding process of the submarine cable, the submarine cable will be dragged on the stern deck of the construction ship, so the submarine cable will produce friction with the deck, and the outer skin of the submarine cable will be worn to varying degrees. In addition, when laying the line or the construction ship turns, the submarine cable has a small fold angle, which not only increases the friction but also easily damages the fiber core. For this reason, a protective mechanism for laying submarine cables is proposed. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] When the utility model is used, the protection mechanism is moved to the surface of the stern deck of the construction ship, and then the submarine cable is passed between the two rollers. At this time, the submarine cable is overlapped on the conveyor belt, and the motor is started to drive the active roller to rotate.

The roller can reduce friction and facilitate line laying. BRIEF DESCRIPTION OF THE DRAWINGS
