Spraying system based on urban rail traffic

Abstract

The invention provides a spraying system based on urban rail traffic. The spraying system comprises a water bottle and high-pressure nitrogen bottle set, a water supply pipe net, a control valve set and novel fine water mist spraying heads, wherein the water bottle and high-pressure nitrogen bottle set is arranged at the bottom of a carriage, the water supply pipe net is arranged at the top and the periphery of the carriage, the control valve set is used for controlling the system to open and close, and the novel fine water mist spraying heads are installed at the top of the carriage; and thewater bottle and high-pressure nitrogen bottle set is connected to the water supply pipe net through the control valve set, and the tail ends of the water supply pipe net is connected to the fine water mist spraying heads. According to the spraying system, a bottle group type power source is adopted, the fire extinguishing structure is simple, and performance is high; and meanwhile, a novel designis carried out on the traditional fine water mist spraying heads, the novel fine water mist spraying heads adopt a dual filter screen structure and a plurality of water mist refining structures, morestable and uniform high-pressure fine water mist can be generated, and the system is more suitable for rail traffic vehicles.

Description

technical field [0001] The invention relates to the field of rail transit safety, in particular to a spray system based on urban rail transit. Background technique [0002] With the rapid development of transportation technology, rail transit facilities have been established in many first- and second-tier cities at home and abroad, and the subsequent fire safety issues of rail transit vehicles have also attracted people's attention. Therefore, how to provide good fire safety protection measures for rail transit is of great significance to the safety of rail transit operations. [0003] At present, rail transit fire protection systems generally face such a problem, that is, when a fire occurs, the fire protection system responds slowly and the fire extinguishing efficiency is relatively low. Due to the unique closed environment of rail transit, rail transit fires are likely to cause disasters of mass death and mass injury. How to activate the fire protection system in a shor...

Problems solved by technology

[0003] At present, rail transit fire protection systems generally face such a problem, that is, when a fire occurs, the response of the fire protection system is slow and the fire extinguishing efficiency is relatively low. However, due to the unique closed environment of rail transit, rail transit fires are likely to cause mass casualties and casualties.
