Cable trench cover plate convenient to install

Abstract

A cable trench cover plate convenient to install of the present invention comprises a supporting rack, a spacer arranged at the lower side of the supporting rack, and an upper plate body arranged at the upper side of the supporting rack. Handles are arranged at the two sides of the supporting rack respectively, the upper plate body is equipped with a plurality of through holes and the installing ports corresponding to the handles, and the supporting rack is a frame body formed by connecting two crossbeams and two longitudinal beams. An inner cavity of the frame body matches the size of the upper plate body, and the cross-sections of the crossbeams and the longitudinal beams are all L-shaped. The upper plate body is embedded in the frame body and is in detachable connection with the frame body, and a plurality of stiffeners are arranged at the bottom of the frame body. The cable trench cover plate of the present invention is lighter in weight, is convenient to open, install and disassemble, also has the enough mechanical strength, can guarantee the personal safety of the operation personnel, and also has the stronger ventilation capability and heat radiation effect.

Description

technical field [0001] The invention relates to a cover plate, in particular to a conveniently installed cable trench cover plate. Background technique [0002] In the substation, the cable trench is designed for sealing due to the needs of fire prevention and small animal prevention. The traditional cable trench cover is generally made of concrete or composite materials, there is no obvious gap between the cover plates, and there is a firewall at a certain distance in the cable trench, which artificially builds a relatively closed space in the cable trench, and the air cannot Circulation, rainwater cannot be evaporated through the exchange of internal and external air; the result of such long-term operation is: moist air will invade into the terminal box along the gap between the cables, forming condensation in the terminal box, resulting in components in the terminal box Corrosion, insulation performance decline, and then induce equipment accidents, affecting the safe ope...

AI Technical Summary

Problems solved by technology

Traditional cable trench covers are generally made of concrete or composite materials, there is no obvious gap between the covers, and there are firewalls at a certain distance in the cable trench, which artificially builds a relatively closed space in the cable trench, and the air cannot Circulation, rainwater cannot be evaporated through the exchange of internal and external air; the result of such long-term operation is: moist air will invade into the terminal box along the gap between the cables, forming condensation in the terminal box, causing components in the terminal box to Corrosion, insulation performance decline, and then induce equipment accidents, affecting the safe operation of the power grid and reliable power supply

At the same time, because the surface of the cover plate is relatively smooth, there is no grasping part installed, which makes the installation and removal of the cover plate more inconvenient. It needs to be installed with the help of auxiliary tools, which affects the construction efficiency
