Description

Technical Field

[0001] This utility model relates to the field of submarine cable transmission, and further to a submarine cable protective sleeve and auxiliary installation equipment. 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 as the material to transmit telephone and internet signals.

[0003] During the laying of submarine cables, a protective sleeve is usually installed on the outside of the cable to protect it and improve its stability on the seabed. Existing submarine cable sleeves are usually of a two-part structure. Before the cable is laid on the seabed, the two halves of the cable sleeve are installed on both sides of the cable and fixed together.

[0004] In existing submarine cable protection sleeves, one end of the sleeve is a large ball end with a larger diameter, and the other end is a small ball end with a smaller diameter. When assembling two adjacent submarine cable protection sleeves, the small ball end of one sleeve is inserted into the large ball end of the other sleeve, thereby achieving a rotatable connection between the two adjacent sleeves.

[0005] Existing submarine cable protection sleeves are typically two interconnected pieces. One half usually has a radially extending limiting post on the outer side of the large ball end, while the other half has an axially extending limiting hook on the outer side of the large ball end. When the two halves are joined to form the submarine cable protection sleeve, the limiting hook is inserted below the limiting post to restrain the two halves.

[0006] It should be noted that in the existing design of submarine cable protection sleeves, when the small ball end of one submarine cable protection sleeve abuts against the inner wall of the large ball end of an adjacent submarine cable protection sleeve, the limiting hook is inserted below the limiting post for limiting. When a half-piece structure limiting hook is inserted below another limiting post, the two half-piece structures will have a certain misalignment in the axial direction. At this time, the large ball end of one of the half-piece structures will abut against the small ball end of the adjacent submarine cable protection sleeve. The operator needs to strike it forcefully to install the limiting hook and the limiting post into place, making the installation process rather cumbersome.

[0007] In addition, in existing submarine cable protection sleeves, the two-piece structure of the submarine cable protection sleeve is usually completely separate. When they are assembled and installed on the outside of the submarine cable, they need to be transported separately, which results in low assembly efficiency and occupies a large assembly space.
