Compact type locomotive-mounted fire prevention and control system

Abstract

The invention discloses a compact type locomotive-mounted fire prevention and control system. The compact type locomotive-mounted fire prevention and control system comprises a data acquisition moduleused for collecting the concentration of carbon monoxide in an equipment cabinet and the temperature in the equipment cabinet, a control module and a fire extinguishing device, wherein the control module is in signal connection with the data acquisition module, judges whether a fire breaks out or not according to data transmitted back by the data acquisition module and controls an electromagneticvalve to be opened so as to feed a fire extinguishing agent into the equipment cabinet. The fire extinguishing device comprises an agent storage tank and the electromagnetic valve. An agent drawing end of the electromagnetic valve is connected with an agent outlet of the agent storage tank, and an agent discharging end of the electromagnetic valve is connected with an agent discharge opening, a control terminal of the electromagnetic valve is in signal connection with the control module, and the agent discharging opening is arranged in the equipment cabinet. The data acquisition module, the control module and the fire extinguishing device are all fixed into the shell. According to the compact type locomotive-mounted fire prevention and control system, the fire extinguishing system in thelocomotive-mounted equipment cabinet is reasonably arranged, the data acquisition module, a master control module, the control module, a display module, a fan and the like are integrated in the system, and safety of passengers and drivers and the railway operation safety are effectively guaranteed.

Description

technical field [0001] The patent of the present invention relates to a compact fire prevention and control system suitable for a built-in vehicle cabinet of a railway locomotive, in particular to a compact vehicle fire prevention and control system. Background technique [0002] The on-board cabinet of railway locomotives, as the load-bearing equipment for the control of the microcomputer network control system and the control of the AC drive system of railway locomotives in my country, its safety in use is very important. According to relevant statistics, there have been 67 extremely serious rolling stock accidents since the founding of the People's Republic of China, 18 of which were related to fires. Part of it is caused by electrical cabinets such as electrical cabinets and AC cabinets. [0003] Since the on-board cabinet is located in the space of the locomotive equipment cabin, it is a hidden fire protection area compared to the drivers and passengers, so it is diffi...

AI Technical Summary

Problems solved by technology

[0003] Since the on-board cabinet is located in the space of the locomotive equipment cabin, it is a hidden fire protection area compared to the drivers and passengers, so it is difficult for personnel to detect the fire at a very early stage. Once the fire is discovered, personnel will open the cabinet to put out the fire. Oxygen enters and induces a larger fire, so it is impossible to extinguish the fire at all, and only peripheral control can wait for the fire to end

[0004] In recent years, although various local railway companies have successively installed some fixed water mist fire extinguishing devices on the locomotives, they have not installed effective fire extinguishing devices inside the electrical equipment and on-board cabinets, and cannot effectively guarantee the safety of drivers and passengers and the safety of railway operations; therefore It is imperative to develop a compact on-board fire prevention and control system that can be built into the on-board electrical cabinet
