Description

Technical Field

[0001] The utility model relates to the technical field of cable protection, in particular to a submarine cable protection device which is easy to locate. Background Art

[0002] The laying of submarine cables usually uses large laying ships to lower the submarine cables to the seabed. The submarine cables will inevitably bend when they are lowered from the ship to the seabed, and the bending transition of the submarine cables will cause damage to the internal structure. Therefore, when the submarine cables are lowered, a protective tube with limited bending will be installed outside the submarine cables to limit the bending degree of the submarine cables.

[0003] For example, Chinese patent CN217789270U discloses a dynamic submarine cable submarine anti-wear protection tube. A large ball head and a small ball head are provided at both ends of the device. The protection tube is bent at a certain angle when passing through the large ball head and the small ball head. At the same time, an inner protective tube is provided on the inner side of the outer protective tube through a spring buffer mechanism, and the submarine cable is flexibly protected by the buffer device.

[0004] However, the submarine cable is in direct contact with the inner wall of the protective tube, and the protective tube is prone to friction with the submarine cable, affecting the service life of the submarine cable; and when the protective tube rotates or moves relative to each other, the submarine cable at the connection between the two protective tubes is in direct contact with the protective tube, and local bending may occur in the area.

[0005] Based on this, the utility model designs a submarine cable protection device which is easy to locate to solve the above problems. Utility Model Content
