Problems solved by technology

[0003] However, many cables are distributed side by side in the existing tray-type cable tray. When the current passing through the cables is large, the cables will generate heat due to excessive current. The aging of the insulating layer of the layer accelerates, and finally the high temperature causes the insulating layer to burn and carbonize, causing a short circuit and even a fire

Embodiment

[0031] Embodiment: a kind of high security cable tray, such as figure 1 and figure 2 , including a tray 1 with a U-shaped cross-section and a cover plate 2 arranged on the upper end of the tray 1. The tray 1 is used to place the cable 4. The cover plate 2 covers the opening of the tray 1 to reduce impurities entering the tray 1. When the cable 4 When working, it generates heat by itself, and the tray 1 and cover plate 2 reduce the heat dissipation of the cable 4. At this time, there are several cooling water pipes 21 distributed in the cover plate 2, and the water inlets of each cooling water pipe 21 pass through a Water inlet pipe 22 enters water, and the water outlet of each cooling water pipe 21 is all communicated by a water outlet pipe 23 (as image 3 ), to facilitate the circulation of water in the cooling water pipe 21, when the cooling water circulates in the cooling water pipe 21, the air temperature in the tray 1 is reduced, thereby reducing the temperature of the ...

Abstract

The invention discloses a high-safety cable bridge, and belongs to the field of cable bridges. The technical scheme mainly includes that the high-safety cable bridge comprises a tray with a U-shaped cross section and a cover plate; the cover plate is arranged at the upper end of the tray, a plurality of cooling water pipes are distributed in the cover plate, water can be fed into water inlets of the various cooling water pipes via a water inlet pipe, water outlets of the various cooling water pipes are communicated with one another via a water outlet pipe, a driving component for driving the cover plate in the tray to get away from the bottom of the tray or driving the cover plate to move towards the bottom of the tray is arranged on the tray, and the water inlet pipe and the water outletpipe are flexible pipes. The high-safety cable bridge has the advantages that the temperatures of the surfaces of cables can be lowered, and accordingly potential safety hazards can be reduced.

Description

technical field [0001] The invention relates to the field of cable bridges, in particular to a high-safety cable bridge. Background technique [0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, supporting arms and installation accessories. The bridge frame in the building can be erected independently or attached to various buildings (structures) and pipe gallery supports. It should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. [0003] However, many cables are distributed side by side in the existing tray-type cable tray. When the current passing through the cables is large, the cables will generate heat due to excessive current. The aging of the insulating layer of the first layer is accelerated, and finally the high temperature causes the insulating layer to burn and carbonize, causing a short circuit and even a f...
