Description

Technical Field

[0001] This invention belongs to the field of cable laying, and specifically relates to a cable trench cover device. Background Technology

[0002] Due to urbanization and the conversion of power lines, cables, and fiber optic cables from exposed to underground conduits, cable trench covers are required. These covers are essential components of cable installation. Historically, cable trench covers have been made of cast iron and cement. However, these covers are not waterproof, are easily stolen and damaged, leading to water ingress into the cable trenches. Furthermore, they are inconvenient to manage and detrimental to safety.

[0003] The existing technology CN205911721U discloses a cable trench cover with waterproof and anti-theft functions, which involves installing an anti-theft alarm and a humidity detector display on the cable trench cover. However, it requires data collection and judgment from the anti-theft alarm in the cable trench cover, which is cumbersome and impractical. Furthermore, it is inconvenient to replace damaged cable trench covers in a timely manner.

[0004] To achieve a unified connection or form a single unit for cable trench covers laid on cable trenches, several cable trench covers need to be connected together, which often requires connectors. However, there are currently no detachable connectors for connecting cable trench covers.

[0005] Existing detachable connectors are generally designed for cable trench covers that need to be connected in large quantities. To facilitate disassembly, a plug-in device is installed between the cable trench cover and the cover mounting strip for connecting them. The existing plug-in device has a cumbersome structure, is not cheap to manufacture, is not easy to disassemble or plug in, and is quite cumbersome to operate. Summary of the Invention
