Abstract

The invention discloses a cable trench-used ventilation cover plate. The cable trench-used ventilation cover includes a cover plate, a protective net and a base. The cable trench-used ventilation cover plate characterized in that the base is a circular base; the edge of a bottom frame of the base is provided with a shelter wall; the bottom frame of the base is movably connected with supporting rods; each supporting rod can rotate around a fixed end by 90 degrees; each supporting rods is provided with at least two grooves; the groove width of the grooves is greater than or equal to the width of net wires of the protective net; and the cover plate is provided with a handle. The cable trench-used ventilation cover plate of the invention has the advantages of simple structure, excellent ventilation effect, simplicity and operational easiness and the like. With the cable trench-used ventilation cover plate adopted, large foreign bodies can be effectively prevented from falling into a cable trench, and therefore, the normal operation of equipment can be ensured.

Description

technical field [0001] The invention relates to a ventilation cover, in particular to a ventilation cover for a cable trench. Background technique [0002] At present, most substations have implemented the unattended mode. How to keep the cable trench clean and dry to ensure the normal operation of the equipment has become an urgent problem to be solved. The existing cable communication vent is usually a cement cover. When ventilation is required, a special person needs to lift it. Foreign objects often fall into the dark and affect normal work. In addition, frequent ventilation to ensure the ventilation of the equipment also requires lifting the cover. Contents of the invention [0003] According to the technical problem raised above, a ventilation cover plate for a cable trench is provided. The present invention mainly utilizes the supporting rods arranged on the base, so as to play the functions of ventilation and protection. The technical means adopted in the presen...
