Description

Technical Field

[0001] The utility model relates to the technical field of submarine cables and optical cable supports, in particular to a submarine cable and optical cable support and a self-locking structure thereof. Background Art

[0002] Submarine cables and optical cables are cables wrapped in insulating materials, laid on the seabed, and used for telecommunication transmission. Submarine cables and optical cables are divided into submarine communication cables and submarine power cables. Modern submarine cables and optical cables use optical fibers as materials to transmit telephone and Internet signals. Submarine cable and optical cable technology is a recognized global problem at home and abroad, but with the continuous progress of society and the rapid development of scientific and technological forces, the application of submarine cable and optical cable technology is becoming more and more extensive, such as island power supply, independent grid connection, offshore wind farms, offshore oil platform power supply, etc.

[0003] Submarine cables and optical cables are usually laid between islands and between countries, with the characteristics of long laying distance and great difficulty. Submarine cables and optical cables have large weight and the submarine environment is very complex, with many external forces, such as the impact of ocean currents, collision with reefs, pressure from seawater, etc. Therefore, in order to protect the safety of submarine cables and optical cables, submarine cables and optical cables need to be connected to parallel steel cables through supports. When laying, the steel cables need to be fixed and laid on the seabed, and the steel cables bear external forces. The cables are attached to the steel cables, thus completing the laying of submarine cables and optical cables.

[0004] Patent No.: CN219779752U, discloses a submarine optical fiber cable support, including an upper support block and a lower support block, one end of the support is directly buckled and connected through a matching connection protrusion and connection groove, and the other end is fixedly connected through a screw rod. Only one end is connected through the screw rod, which saves half of the assembly time and improves the assembly efficiency of the support; the contact end is arranged at both ends of the support, the cable hole is arranged at the center of the support, and the screw hole is arranged at the steel cable hole and the middle position of the cable hole, which effectively improves the stable support effect of the support on the optical fiber cable and the steel cable; a plurality of adjacent strip grooves are evenly arranged on the inner side of the cable hole, and the plurality of strip grooves save the material amount of the support; the top of the strip groove is in an arc shape, and each corner of the strip groove is provided with a rounded corner. The arc shape and the rounded corner design improve the demoulding efficiency of the support; the screw nut is a four-corner nut. Compared with the hexagonal nut, the four-corner nut can reduce the number of slippage, improve the tightening force of the screw, and improve the stability of the support.

[0005] The submarine optical fiber cable support of the above-mentioned related patent still has a disadvantage, that is, it still needs to be connected by screws, which is time-consuming and laborious for workers to assemble and has low efficiency.

[0006] The present application proposes a submarine cable and optical cable support with a self-locking structure, which does not require screw connection, and only requires external force to apply to the upper and lower support blocks to self-lock and combine. It is easy to operate, saves time and effort, and has a high installation efficiency. Utility Model Content
