Description

Technical Field

[0001] This utility model relates to a burying device for laying submarine cables, belonging to the field of submarine cable laying technology. Background Technology

[0002] Submarine cables are cables wrapped in insulating material and laid on the seabed for telecommunications transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Modern submarine cables use optical fibers to transmit telephone and internet signals. When laying submarine cables, ships are often used to power and pull trenching equipment to excavate trenches on the seabed, where the cables are then laid.

[0003] Existing burial equipment suffers from the high fluidity of marine mud and the constant flow of seawater, causing the extracted mud to be immediately filled with other marine mud, thus affecting the efficiency of cable burial. Therefore, we propose a burial device for submarine cable laying to solve the above problems. Utility Model Content
