Abstract

The invention provides an underground protection device for optical cables in traffic engineering construction, which includes an annular platform and a sealing ring; the outer cylinder is a cylindrical structure; the fixing bolt is a bolt structure, which is connected to the upper cover and the outer cylinder through threads, Fix the upper cover and the outer cylinder together; the arc groove is set on the top side of the floating block, and the arc shape is the same as the inner wall of the outer cylinder; there are three hooks, which are located at the right end of the outer circle of the outer cylinder as intervals. 120-degree equal arc circular distribution; the annular groove is a circular groove structure, which is set on the left side of the outer cylinder, and a sealing ring is respectively set on the small diameter and the large diameter of the groove; the structure of the present invention Simple, low cost, easy to install and disassemble, convenient for follow-up maintenance and repair, and provide a layer of external protection for the optical cable to reduce the phenomenon of water immersion of the optical cable. , to reduce the amount of internal water and prevent water from affecting optical signal transmission.

Description

technical field [0001] The invention belongs to the technical field of optical cable protection devices, and more specifically relates to an underground protection device for optical cables in traffic engineering construction. Background technique [0002] In traffic engineering, optical cables for communication are often routed underground, and the underground environment is relatively humid. [0003] Based on the above, the inventors have found that the underground passage is prone to water ingress in rainy days, the optical cable is easily immersed in water, and the optical signal transmission efficiency will be affected when the optical cable connection is damp, and the optical cable is usually exposed in the pipeline without protective measures. , susceptible to mouse gnawing leading to loss of optical transmission signal. [0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an underground protection device for optical c...
