Transparent cover board capable of being wiped

Abstract

The invention discloses a transparent cover board capable of being wiped, which comprises tempered glass and a bracket, wherein the tempered glass is arranged on the bracket; the bracket comprises a guide rail and a cross arm; the cross arm is arranged on the guide rail in a sliding manner and is provided with a wiping mechanism; the wiping mechanism is attached to the lower surface of the tempered glass; and the cross arm is provided with a permanent magnet. Compared with the prior art, the transparent cover board capable of being wiped disclosed by the invention becomes a transparent structure from an originally non-transparent structure; the lower surface of the cover board can be wiped clean even if the lower surface of the cover board is misted or water drops are formed by moisture condensation; the lower surface of the cover board is prevented from dust or debris; the cover board is kept in a transparent state; and the condition that an inspector can timely grasp the condition in a cable channel without turning over the cover board is facilitated.

Description

technical field [0001] The invention relates to the field of power engineering materials, specifically a wipeable transparent cover plate. Background technique [0002] In order to prevent the spread of cable fires, cable trenches with a length of more than 100m, the entrance where cables enter the room from the outside, and the entrance and exit of cable shafts, etc., should refer to the requirements of the "Code for Fire Protection Design of Thermal Power Plants and Substations" GB50229-1996, set Fireproof partition. For the sake of safety, inspectors need to inspect the situation of the cable trench regularly, and they need to know the situation in the cable trench every time they inspect. At present, the existing fire partition wall covers are made of cement or metal materials, which mainly have the following disadvantages: 1. It is opaque, and inspectors cannot easily see the situation in the cable trench; 2. It is too bulky and inconvenient to carry It also makes it ...

AI Technical Summary

Problems solved by technology

At present, the existing fire partition wall covers are made of cement or metal materials, which mainly have the following disadvantages: 1. It is opaque, and inspectors cannot easily see the situation in the cable trench; 2. It is too bulky and inconvenient to carry It also makes it inconvenient for inspectors to observe the situation in the cable trench

[0003] In addition, although transparent fireproof partition wall covers have appeared now, in actual use, since the cable trench is outdoors, the lower surface of the cover is prone to fogging or condensation into water drops at low temperatures. At the same time, over time, the wet lower surface of the cover is also easily contaminated with dust or debris, causing the transparent cover to become opaque, making it impossible for inspectors to see the situation inside the cable trench
