Submarine cable protection apparatus

Abstract

The invention discloses a submarine cable protection apparatus. The submarine cable protection apparatus comprises a protection pipe arranged on a cable in a sleeving manner; the protection pipe is sleeved with two arc-shaped locking blocks; a first locking block and a second locking block which are arranged symmetrically are fixedly mounted on each arc-shaped locking block; the first locking block is positioned above the second locking block; a movable groove is formed in the bottom of the first locking block; the same fixed plate is fixedly mounted on the two side inner walls of the movablegroove; a movable rod is glidingly mounted on the fixed plate; a fixed block is fixedly mounted at the bottom of the movable rod; and the top of the fixed block is in contact with the bottom of the fixed plate. By virtue of the submarine cable protection apparatus, effective protection on the cable can be provided, and the protection pipe can be mounted and fixed conveniently, and the positions ofthe arc-shaped locking blocks can be adjusted conveniently, thereby adapting protection pipes of different lengths; and by protecting the protection pipe by a first protective pipe and a second protective pipe on each arc-shaped locking block conveniently, the overall protection performance is improved, and the submarine cable protection apparatus is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of cable protection equipment, in particular to a submarine cable protection device. Background technique [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. Submarine communication cables are mainly used for long-distance communication networks, usually between long-distance islands, across For more important occasions such as naval and military facilities, the laying distance of submarine power cables is much shorter than that of communication cables. It is mainly used for the connection between land and islands, across rivers or harbors, from land to drilling platforms or between drilling platforms. etc., after searching, the patent document with the authorized announcement number CN205900148U discloses a submarine cable bending protecti...

[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. Submarine communication cables are mainly used for long-distance communication networks, usually between long-distance islands, across For more important occasions such as naval and military facilities, the laying distance of submarine power cables is much shorter than that of communication cables. It is mainly used for the connection between land and islands, across rivers or harbors, from land to drilling platforms or between drilling platforms. etc., after searching, the patent document of authorized announcement number CN205900148U discloses a submarine cable bending protection device, which includes a chain structure composed of at least two bending limiter modules interlocking with each other, and each bending limiter module consists of two symmetrical structural units Connected by bolts and positioned by positioning pins, the symmetrical structure unit includes three parts connected in sequence: head, neck and tail. The head is set as a convex ring structure, and the inner side of the tail is set as a groove structure. The groove structures are occluded and connected with each other. The center of the symmetrical structural unit is provided with a through hole for the submarine cable to pass through. The symmetrical position of the side of the symmetrical structural unit is provided with bolt holes, and the side is symmetrically provided with positioning pin holes near the edge. The modular unit structure can change its overall length arbitrarily according to the requirements. At the same time, the unit adopts a symmetrical locking structure, which is convenient for installation on the submarine cable. The positioning pin design prevents the symmetrical unit from moving and makes the symmetrical unit more tightly combined. The protection effect of this protective device is not very good, it is not convenient to provide effective protection for submarine cables, and submarine cables are still vulnerable to damage, so we propose a submarine cable protection device to solve the above problems
