Abstract

This application relates to a cable trench fireproof sealing system, including: a plurality of support parts arranged at intervals along the extending direction of the cable trench, the support parts are used to support cables, the support parts are arranged at intervals from the bottom of the cable trench, The sensitive material is fixed on the side wall of the cable trench, and a heater is installed inside the heat-sensitive material; the fire extinguishing agent nozzle is set on the top of the cable trench, and the orthographic projection of the fire extinguishing agent nozzle on the bottom of the cable trench and the supporting part are at the bottom of the cable trench The projection coincides; the smoke sensor is set between two adjacent support parts and is located on the top of the cable trench, the smoke sensor is electrically connected to the heater, and the smoke sensor is also connected to the main power supply; the fire resistance wall is set on Between the support part and the fire extinguishing agent nozzle, and block the fire extinguishing agent nozzle. When the smoke sensor reaches the alarm state, control the heater to heat at the same time, and control the main power to be turned off. After the fire extinguishing agent nozzle loses its resistance, it starts to spray fire to the cable trench agent.

Description

technical field [0001] This application relates to the field of electrical safety, in particular to a fireproof sealing system for cable trenches. Background technique [0002] Cable trench laying refers to a cable installation method in which cables are laid in pre-built cable trenches. It is suitable for cable route paths with light load on the ground, such as sidewalks, grounds in factories, etc. The fire resistance of the cable trench is often the key to ensure the safety performance of the cable connection. The existing cable trench has poor fire resistance, which brings unsafe factors. Contents of the invention [0003] Based on this, it is necessary to provide a cable trench fireproof sealing system for the above problems. [0004] A fireproof sealing system for a cable trench, comprising: [0005] A plurality of support parts arranged at intervals along the extension direction of the cable trench, the support parts are used to support cables, the support parts ...
