Flexible high-pressure water mist safety system for rail transit

Abstract

The invention relates to a flexible high-pressure fine water mist safety system for rail transit. The flexible high-pressure fine water mist safety system for rail transit comprises a plurality of carriages, each carriage is provided with a three-way magnetic valve, a branch pipe and a plurality of spray heads. Two water pumps and a main water pipe are used in common by the multiple carriages. Each water pump is provided with a three-way pipe, wherein one pathway of the three-way pipe communicates with the water pump and the other two pathways communicate with the main water pipes at both ends. The two pathways of the three-way magnetic valve of each carriage are each connected with the main water pipe, and the another pathway is connected with the corresponding branch pipe. Each branch pipe extends to the top of the corresponding carriage and is connected with the multiple spray heads. A gas-proof water mist door device is positioned at a carriage door of each carriage and an explosion-terror-proof hydraulic giant is positioned in each carriage. The flexible high-pressure fine water mist safety system for rail transit can separately control the operating of the spray heads in single carriage and control the water volume, has a good fire extinguishing effect, can inhibit toxic gas diffusion, can subdue criminals through the hydraulic giant, and can ensure that rail transit vehicles run safely and stably.

Description

technical field [0001] The invention relates to a fire safety system, in particular to a flexible high-pressure fine water mist safety system for rail transit. Background technique [0002] At present, rail transit is already the most widely used means of transportation for people to travel, especially during holidays, when the number of passengers is complex and the compartments are relatively crowded. The traditional rail transit fire extinguishing device adopts an integral structure. If a fire occurs in a carriage, the pressurized water in each carriage will not be sprayed from the nozzle. Due to the limited amount of water stored in the train, if it is sprayed in this way, the water will be sprayed out in a very short time, causing the fire compartment to still burn. Can not achieve fire extinguishing effect. If some criminals release poisonous gas in the compartment, the poisonous gas can only be discharged by opening the window, which will not only cause harm to the ...

AI Technical Summary

Problems solved by technology

If some lawbreakers release poisonous gas in the compartment, the poisonous gas can only be discharged by opening the window, which will not only cause harm to the life safety of passengers, but also spread to other compartments quickly. It does not have the function of suppressing poisonous gas, nor does it have the function of high-pressure water guns to subdue criminals
