A fire early warning fan for subway station tunnel

Abstract

The present application discloses a fire early warning fan for a subway station tunnel, which includes an air intake mechanism, an air exhaust mechanism, a temperature detection assembly and two fire extinguishing assemblies; the input end of the air intake mechanism and the output end of the air exhaust mechanism are respectively connected to the outside of the tunnel. The output end of the air intake mechanism and the input end of the air exhaust mechanism are both located in the tunnel; the temperature detection component is arranged between the air intake mechanism and the air exhaust mechanism, and is connected with the two fire extinguishing components respectively, which can control the two fire extinguishing components. Action to achieve fire extinguishing; two fire extinguishing components are respectively arranged on the outside of the air inlet mechanism and the air exhaust mechanism. The application realizes the independent operation of the air intake and exhaust in the tunnel, quickly handles the heat and dust generated during the operation of the train, and can quickly capture the temperature rise point, extinguish the ignition point in time, and effectively control the occurrence of fire. Purpose.

Description

technical field [0001] The present application relates to the technical field of tunnel ventilation equipment, and in particular, to a fire early warning fan for subway station tunnels. Background technique [0002] The subway is a fast, large-capacity, electric-driven rail transit built in the city. Trains run on fully enclosed lines. Lines located in the central urban area are basically located in underground tunnels. Lines outside the central urban area are generally located on viaducts or on the ground. , High-density, high-volume urban rail transit system, the subway in Taiwan, China is called "MRT". In addition to the subway, it also includes elevated railways or railways laid on the road. Therefore, the subway is the exclusive right of way, without Level crossing, this is also the fundamental sign that the subway is different from the light rail transit system. The earliest (and the first) subway in the world is the Metropolitan subway in London, England, which was b...

AI Technical Summary

Problems solved by technology

[0004] This application provides a fire warning fan for subway station tunnels, which solves the problem that the fan in the tunnel in the prior art uses a single-pipe exhaust and air intake, so that the heat and dust generated by frequent train running cannot be quickly processed, which in turn causes the fire in the tunnel. The technical problem of accumulation and easy to cause spontaneous combustion and fire has realized the independent operation of air intake and exhaust in the tunnel, and can quickly deal with the heat and dust generated during the operation of the train. At the same time, it can quickly capture the temperature rise point and timely treat The purpose of extinguishing the ignition point and effectively controlling the occurrence of fire
