A cable protection device for extreme environments

Abstract

The invention provides a cable protection device for an extreme environment. The device comprises a housing and a top cover fixedly connected with the upper end of the housing through a plurality of fastening screws; the housing is of a strip-shaped structure; the housing is located in soil; a plurality of cable trays are disposed in the inner cavity of the housing; adjacent ends of the pluralityof cable trays are hinged to each other; the lower ends of the cable trays are connected with the inner bottom wall of the housing through supporting devices; the inner bottom wall of each cable trayis fixedly connected with a heating plate; and the inner side walls of the cable tray are fixedly connected with a grid plate. With the cable protection device of the invention adopted, deficiencies in the prior art can be eliminated. The cable protection device has the advantages of reasonable design and compact structure. With the cable protection device adopted, cables can be effectively protected; the temperature stability of the cables is effectively maintained; the normal use of the cables is ensured; the service lives of the cables in the extreme environment can be prolonged; and the maintenance costs of the cables can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of cable protection equipment, in particular to a cable protection device used in extreme environments. Background technique [0002] Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are composed of single-strand or multi-strand wires and insulating layers, and are used to connect circuits, electrical appliances, etc. Cables are usually twisted by several or groups of wires (at least two in each group). Insulated from each other and often twisted around a center, the entire outside is covered with a highly insulating covering. The cable has the characteristics of internal electrification and external insulation. [0003] Existing cable protection devices are roughly divided into trough-type, tray-type, ladder-type, g...

AI Technical Summary

Problems solved by technology

[0003] Existing cable protection devices are roughly divided into trough-type, tray-type, ladder-type, grid-type and other structures. When used in extreme environments, all parts need to be galvanized, and in extreme environments, whether it is too cold Or too hot will affect the use of the cable or even damage the cable

At present, most of the cable protection devices are composed of cable trays. In extreme environments, it is impossible to ensure the safety of the cables, and it is also impossible to ensure that the cables can be used normally at a certain temperature. This brings a lot of trouble to the staff, so we propose A cable protection device for extreme environments
