Embodiment Construction

[0020] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] The invention provides a cable trench firewall to solve the problems of difficult maintenance and potential safety hazards in the prior art.

[0022] Specifically, for the cable trench firewall, see figure 1 , including: a transparent upper cover 101, a baffle and a plurality of fireproof bags; wherein:

[0023] The baffle includes a first fireproof board 102 and a second fireproof board 103 that are anti-corrosion and waterproof;

[0024] A plurality of fireproof packages are tightly and evenly arranged between the first fireproof board 102 and the second fireproof board 103;

[0025] The upper surface of the transparent upper cover 101 is a non-slip surface, and the lower surface is an anti-fog and fire-proof surface. The lo...

Abstract

The invention provides a cable duct firewall. The cable duct firewall is manufactured from a fireproof material, and has a fireproof function; meanwhile, cable standby holes are formed in the cable duct firewall so as to facilitate later dilatation or exchange maintenance, and the cable duct firewall is not need to be dismantled; a water-flowing flood prevention tank is formed in the cable duct firewall so as to facilitate water-flowing flood prevention and washing maintenance in a cable duct; moreover, a baffle plate of the cable duct firewall is manufactured from fireproof plates capable of preventing corrosion and water, so that corrosion of the fireproof plates is avoided; a transparent upper cover of the cable duct firewall is transparent, the upper surface is antiskid, the lower surface is anti-fog and fireproof, and the bearing pressure is greater than a preset pressure value, so that potential safety hazards in the prior art are avoided.

Description

technical field [0001] The invention relates to the technical field of cable trench fire prevention, in particular to a cable trench firewall. Background technique [0002] At present, the firewalls of the cable trenches of many power companies are mostly made of bricks and coarse sand; the cable trenches of some power plants and substations use simple firewalls made of fireproof boards, fireproof bags, and fireproof mud. [0003] However, with the increasing development of the power system and the continuous updating of various equipment, the construction or transformation of intelligent substations has begun. Therefore, the traditional firewall can no longer meet the current technical standards. For example, in the later expansion or replacement maintenance, the firewall must be removed to add or replace the cable; when it rains, the cable trench is filled with sludge water, resulting in long-term It is not clean because it is wrapped in sludge, which brings inconvenience...
