Optical cable ground laying optical fiber protection device

Abstract

The invention relates to an optical cable ground laying optical fiber protection device. The optical fiber protection sleeve solves the problem that an optical fiber protection sleeve in the prior art is poor in protection effect. The device comprises a protective outer tube, a protective inner tube used for loading optical fibers is arranged on the circumferential inner side of the protective outer tube, a supporting gap is formed between the protective inner tube and the protective outer tube, and a plurality of elastic pressure buffering mechanisms with one ends fixedly connected with the circumferential inner wall of the protective outer tube and the other ends connected with the protective inner tube through insertion connection assemblies are arranged in the supporting gap. And a plurality of pressure-resistant damping assemblies are spirally arranged on the outer wall of the protective outer pipe in the circumferential direction, and a pressure conduction mechanism is arranged between every two adjacent pressure-resistant damping assemblies and located on the outer wall of the protective outer pipe. The optical fiber protection device has the advantages that the protection effect is good, and damage of external pressure to the optical fiber is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of optical fiber protection, in particular to an optical fiber protection device for laying optical cables on the ground. Background technique [0002] Optical fiber, short for optical fiber, is a fiber made of glass or plastic that acts as a light-transmitting tool. Optical fibers are widely used in various engineering fields because of their unique advantages such as strong chemical corrosion resistance, good electrical insulation performance, small size, light weight, strong adaptability, and low cost. The laying of optical cables is the first and key step in engineering applications, so the protection of optical fibers during the laying process is the top priority in the entire project. Most of the current optical cable ground laying sites are manually compared, and the optical cable is placed in it with bricks with reserved slots, and then the bricks are tamped on the ground by knocking from above.

Problems solved by technology

[0004] The above-mentioned solution solves to a certain extent the problems in the prior art that the optical fiber protective sleeve is not easy to be flexibly disassembled and inconvenient to use after being connected, but this solution still has many deficiencies, for example: the protective sleeve cannot withstand the Vertical pressure, and the optical fiber itself is too fragile and easy to break, the optical fiber is easy to withstand high pressure and damage, affecting communication, and the protection effect is not good
