A self-falling plate heat-insulating cable tray

Abstract

The invention discloses a self-falling plate heat-insulating cable bridge, which belongs to the technical field of cable installation. The invention uses a combination of heat-insulation warning balls and the like. When the temperature of a certain cable is too high, the cable corresponds to a heat-insulation warning The hard and soft touch body in the ball will be heated and softened, so that the inflatable balloon can be expanded, thereby driving the heat-insulating driving adjustment rod to push the linkage cross bar, so that all the heat-insulating plates automatically fall into the bridge chassis, and then can play an isolation protection It can significantly reduce the influence of overheated cables on the rest of the cables, prevent the rest of the cables from being damaged, and greatly improve the safety performance, and the movement of the linkage crossbar will also trigger the buzzer to make the buzzer sound Warning, so that the relevant staff can find out the phenomenon that the cable temperature is too high in time, and through the setting of the heat insulation push rod, reflective rod, etc., the cable with abnormal temperature can be quickly found through the reflection of the reflective rod, which greatly improves the practicability.

Description

technical field [0001] The invention relates to the technical field of cable installation, and more specifically relates to a heat-insulating self-falling plate cable tray. Background technique [0002] With the development of intelligent buildings, there are often AC strong current systems, weak current systems, DC strong current systems and various automation systems in the same building, such as building automation systems, office automation systems, communication automation systems, etc. Therefore, it is necessary to lay various types of cables such as AC strong current cables, DC strong current cables, communication cables in weak currents, and control cables at the same time. Various cables need to be wired separately when designing and wiring. Cable trays are gradually being used on a large scale. [0003] Cable bridges are divided into trough type, tray type, ladder frame type, grid type and other types. The bridge frame in the building can be erected independently ...

AI Technical Summary

Problems solved by technology

[0004] During the use of the cable, it is easy to cause the temperature to be too high due to abnormal current and other reasons. If the cable temperature is too high, it will easily damage the cable and even cause a fire. In the cable tray in the prior art, multiple cables are usually directly laid in parallel on the bridge. In this case, the distance between the cables is short and there is no isolation protection measure, so that when one of the cables is overheated, the heat will be transferred to other cables, causing other cables to be damaged accordingly.
