Embodiment 1

[0032] Such as Figure 1 to Figure 3 As shown, the cable trench cover plate of this embodiment is used to cover the cable trench to protect the cables in the cable trench. The cable trench cover includes a base 1, a protective net 5 and a cover 3 that cooperates with the base 1 and covers the outside of the entire cable trench cover.

[0033] Base 1 cover among the present embodiment is arranged on the cable ditch, has installation opening on it; Protection net 5 is arranged on the installation opening, and protection net 5 includes two sub-protection nets, and at least one sub-protection net can be mounted on the installation opening. It is arranged to move back and forth, and when the movable sub-protection net moves to an overlapping position with another sub-protection net, the installation opening on the base 1 will be opened to form an inspection port 11 that can be used for overhauling the cable trench; the cover plate 3 , cooperate with the base 1 in a hinged manner, ...

Abstract

The invention provides a cable groove cover plate. The cable groove cover plate comprises a base, a protection net and a cover plate, wherein the base is covered on a cable groove, an installation hole is formed in the base, the protection net is arranged on the installation hole and at least comprises two protection sub-nets, at least one protection sub-net is movably arranged on the installation hole in reciprocating way, an opening formed by moving the protection sub-net to be overlapped with the other protection sub-net is an access hole, and the cover plate is covered on the base and can cover the projection net. In the cable groove cover plate provided by the embodiment of the invention, the whole cable groove cover plate is not needed to be carried no matter during the ventilation process of the cable groove or the maintenance process of the cable groove by ingeniously arranging the projection nets in many blocks and arranging and designing the protection sub-nets to be movable under the condition of improving the safety, the workload is reduced, and the working efficiency during the process of maintenance and ventilation to remove dampness is improved.

Description

technical field [0001] The invention relates to the technical field of substation construction, in particular to a cable trench cover plate. Background technique [0002] At present, the cable trench cover plate is mostly made of cast iron or cement, and is lapped on the cable trench to seal the cable trench. When performing maintenance work or ventilating and dehumidifying the cables in the cable trench, it is necessary to remove the cable trench cover first, and then expose the cable trench for related operations. In actual operation, taking the cable maintenance in the cable trench in the current 110KV substation as an example, the number of cable trench covers is between 400 and 600, and the weight of each cable trench cover is between 50 and 100kg. Construction workers need to move the cable trench cover away from the cable trench when performing regular maintenance or ventilating the cable trench. The work intensity of the entire cable trench cover is very high. [0...
