Abstract

The invention provides a cable trench cover plate. The cable trench cover plate comprises a cover plate body and a plurality of ventilating holes which penetrate through the cover plate body; a cavitystructure is formed in the ventilating holes; and the area of the cavity structure gradually increases from top to bottom. In addition, the cable trench cover plate further comprises a temperature detection alarm device and a dry powder fire extinguishing ball. By virtue of the cable trench cover plate, a situation that the ventilating holes are blocked can be effectively prevented; and the easily caused problem of unsmooth ventilation of the cable trench, too high temperature, and incapability of finding abnormal temperature in the trench and performing fire extinguishing in time when the ventilating holes of the cable trench cover plate are blocked can be solved.

Description

technical field [0001] The present application relates to the technical field of electric equipment, in particular to a cable trench cover. Background technique [0002] The cable trench is the main channel of the city's power supply cables. It is mainly located on the sidewalk. The concrete manhole cover has the functions of opening and cable communication and cooling. In the process of realizing the present invention, the inventor found that the prior art has at least the following technical problems: the ventilation holes of the existing cable trench cover are easily blocked by dirt, stones, leaves and other sundries, resulting in poor ventilation of the cable communication and high temperature. If the temperature is too high, the abnormal temperature in the trench cannot be detected in time. When the cable trench catches fire, it cannot be found and extinguished immediately, which seriously affects the safe operation of the cable and reduces the reliability of power supp...
