Problems solved by technology
[0003] For the control cable trays for laying computer cables, communication cables, thermocouple cables and other highly sensitive systems, the trough-type fully enclosed cable tray is generally used. In order to ensure the trough-type cable installation, the cables can be firmly fixed during long-term use. In the cable tray, there will be no side-to-side shaking, no corrosion by the external environment, and prolonging the service life of the internal cables. It is necessary to increase the fixed structure and ventilation of the trough-type cable device. Therefore, ventilation holes are provided on the side of the trough-type cable device. But there will be a lot of dust entering the interior of the cable device from the ventilation hole, covering the cable, and affecting the communication characteristics of the cable

Embodiment Construction
[0013] Such as figure 1 As shown, a trough type cable tray device of the present invention adopts a technical solution as follows: a trough type cable tray device, comprising a trough frame body 1 with an open port structure, and the bottom plate of the trough frame body 1, etc. Several positioning protrusions 2 are provided at intervals, and the positioning protrusions 2 are X-shaped. On the top plate of the groove frame body 1 and corresponding positions of the positioning protrusions 2, there are several positioning protrusions 2 at equal intervals for fixing cables. The fixing holes 3 are symmetrically arranged on both sides of the frame body 1 with a plurality of ventilation holes 4 distributed at equal intervals, and each ventilation hole 4 is provided with a dust-proof filter screen 5 .
[0014] The shape of each ventilation hole 2 is a semicircle.
[0015] Further, the dust-proof filter screen 5 is composed of a plurality of mesh holes, and the diameter of the mesh ho...

The invention relates to a groove type cable bridge device which comprises a groove frame body with ports of open structures. A plurality of positioning protrusions are arranged on a bottom plate of the groove frame body at equal intervals, each positioning protrusion is in an X shape, a plurality of fixing holes used for fixing cables are formed in positions, corresponding to the positioning protrusions, of a top plate of the groove frame body at equal intervals, a plurality of ventilation holes distributed at equal intervals are symmetrically formed in the two sides of the groove frame body, and each ventilation hole is provided with a dustproof filter screen. By the adoption of the groove type cable bridge device, the cables can be fixed through the positioning protrusions and the fixing holes and prevented from shaking leftwards and rightwards, a large amount of dust can be filtered through the dustproof filter screens and prevented from covering the cables in the groove frame body, the service life of the cables in the groove frame body is prolonged, and the groove type cable bridge device has the advantages of being simple in structure and convenient to use and having good application prospects.
Description
technical field [0001] The invention relates to the technical field of power supply and distribution, and more specifically relates to a trough type cable bridge device. Background technique [0002] Cable tray is the main equipment used to regulate the safety of cables and transmission lines in infrastructure projects. 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. [0003] For the control cable trays for laying computer cables, communication cables, thermocouple cables and other highly sensitive systems, the trough-type fully enclosed cable tray is generally used. In order to ensure the trough-type cable installation, the ca...
