Adjustable intelligent cable tray

Abstract

The invention provides an adjustable intelligent bridge. The invention has a simple structure and good heat dissipation. It can be assembled flexibly according to the actual situation of the site terrain. It can change the orientation and length of multiple angles, avoid obstacles, and can complete multiple angles. Adjustment to realize the steering function in the cable line, the invention does not need on-site measurement, can be directly manufactured in factory standardization, easy processing, mass production, low cost, beautiful appearance, easy installation; through rectangular cooling holes, cooling fans, The heat dissipation efficiency is improved, the heat dissipation effect is good, and the heat generated by the cable can be greatly reduced; the sand interlayer is set in the middle of the installation plate, the side plate, and the support frame to achieve the effect of fire prevention and flame retardant; through the PLC controller and the temperature alarm. Intelligent control of bridge heat dissipation.

Description

technical field [0001] The invention relates to the field of bridges, in particular to an adjustable intelligent bridge. Background technique [0002] The cable tray product is a new type of cable laying device developed by industrially developed countries in the early 1960s. With the high development of electrification and automation, especially the change of power distribution mode, the direct burial of trenches and the laying of cables on brackets can no longer meet the requirements of use, and they are replaced by cable trays, thus speeding up the construction progress, ensuring quality, and realizing product quality. Standardization, serialization, generalization. Cable tray is a device for fixing cables, widely used in petroleum, chemical industry, electric power, light industry, telecommunications and other industries, mainly used for the laying of overhead power cables, control cables, lighting lines, and telecommunication cables. Commonly used bridges are generall...

AI Technical Summary

Problems solved by technology

When a bridge is required for cable laying, when faced with multi-fork intersections and complex and changeable engineering erection environments, the bridge installation cannot change the shape of the facility, and it is difficult to mount the cables, the installation is difficult, and the style is not beautiful after installation. Cable placement looks cluttered

Existing cable trays usually have ventilation holes punched out on the bottom and sides, and the external natural wind is used to radiate the heat inside the cable tray. When blowing directly into the bridge frame, the cold air is difficult to disperse, and the cables cannot be fully cooled. At the same time, after the cables are placed in the bridge frame, the ventilation holes are easily blocked by the cables, which cannot achieve the purpose of ventilation and heat dissipation. It is easy to cause fire after a long time
