Buried warning cable

Abstract

The invention discloses a buried warning cable which comprises a cable body and a protection device, wherein the protection device is arranged at the bottom of the cable body. The protection device comprises an outer shell, a containing cavity is formed in the middle of the outer shell, the bottom surface of the containing cavity is an arc-shaped surface, the arc-shaped surface of the outer shellis filled with a rubber capsule, a first arc-shaped concave surface is arranged on the upper end surface of the rubber capsule, an opening is formed in the top of the rubber capsule, limit baffle plates are arranged on two sides of an opening end of the rubber capsule, a floating part is arranged at the upper end of the rubber capsule, a second arc-shaped concave surface is arranged at the upper end of the floating part, the second arc-shaped concave surface of the floating part is filled with the bottom of the cable body, and the top of the cable body extends out of the upper end surface of the outer shell. The buried warning cable is simple in structure and has good safe protection ability and cooling performance, effective early warning can be achieved, and use safety of the cable is improved.

Description

technical field [0001] The invention relates to a cable, in particular to an underground warning cable. Background technique [0002] Buried cables are often buried in the soil, and they often face pressure during use, resulting in damage to the cable due to excessive pressure or shearing. Although many cables have anti-shearing structures, they face relatively large external forces. When cutting, this safety structure will not play any role at all, so it is necessary to set up a warning function, so that the operator can find out in time to prevent further cutting. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a buried warning cable, which can effectively serve the purpose of early warning, has very good safety protection ability and heat dissipation performance, and increases the safety of cable use. [0004] The present invention is achieved through the following technical solutions: a buried warning cable,...
