Self-falling plate heat insulation type cable bridge

Abstract

The invention discloses a self-falling plate heat insulation type cable bridge, and belongs to the technical field of cable installation. Through combined arrangement of touch heat insulation warning balls and the like, when the temperature of a certain cable is too high, a hard and solid soft touch body in the touch heat insulation warning ball corresponding to the cable can be heated and softened, so that an inflation balloon is expanded, and therefore, a heat insulation driving and adjusting rod is driven to push a linkage cross rod, all heat insulation plates automatically fall into a bridge chassis, an isolation and protection effect can be achieved, the influence of the over-high-temperature cable on other cables is remarkably reduced, the other cables are prevented from being damaged along with the cable, and the safety performance is greatly improved; and the movement of the linkage cross rod can trigger and start a buzzer, so that the buzzer makes a sound to give an alarm, related workers can timely find out the phenomenon that the temperature of the cable is too high; and through the arrangement of a heat insulation push rod, a light reflection rod and the like, the cable with the abnormal temperature can be rapidly found out through light reflection of the light reflection rod, and the practicability is greatly improved.

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.
