Mining trucks, scrapers, rock drilling rigs, shearers, support trucks, mining trackless rubber-tired trucks and other mining vehicles shuttle back and forth in coal mines, gold mines, iron ores, copper mines and nonferrous metal mines. It is in uninterrupted operation and is the main artery of mine production. Its fire safety cannot be ignored. Due to the compact internal structure and small space of the mine car, once a fire occurs, the fire spreads quickly and is difficult to put out, so the portable fire extinguisher cannot exert its own value. How to reduce and reduce the economic property losses of mining companies and ensure personnel safety? At this time, a new automatic fire extinguishing device that breaks tradition and is smart and innovative is needed - the mine car automatic fire extinguishing system, which can realize unmanned automatic start, quickly suppress and extinguish fires, and protect the lives and property safety of mining company personnel to the greatest extent.
Combustion is a chemical reaction that emits heat and light. Its essence is a chain reaction of free radicals. Due to the continuous chain reaction, combustion continues. Once the reaction starts, free radicals will quickly act on other compound molecules participating in the reaction to generate new free radicals. This will go through many chain reaction steps until the reactants are completely reacted, the free radicals disappear, the chain reaction is interrupted, and the combustion stops. The mine car automatic fire extinguishing system is different from the traditional fire extinguishing method, breaking the old pattern of passive fire extinguishing and creating a new situation of active defense and independent fire extinguishing. Use high-efficiency water-based fire extinguishing agents to quickly suppress and control the fire. While vaporizing and absorbing heat reduces the temperature of the fire scene, it isolates the oxygen required for combustion and shuts down the combustion reaction, thereby achieving the purpose of suffocating the fire and suppressing re-ignition for a long time.
System advantages and features:
Compared with traditional fire extinguishing methods, mine car automatic fire extinguishing systems respond more quickly, extinguish fires more intelligently, operate more safely and stably, and are equipped with "safety locks" for special vehicles above and below mines.
1. Faster response: The system is transmitted from the detector to the control system, and has the function of automatically triggering and starting the fire extinguishing device at the moment of fire, with rapid response and strong autonomy.
2. Fire extinguishing is more intelligent: The system does not require human participation and integrates fire detection, alarm and fire extinguishing, achieving autonomous and efficient fire extinguishing performance in an unmanned state.
3. The operation is safer and more stable: the system is equipped with a sound and indication fire alarm, which automatically warns and extinguishes the fire the moment it occurs, greatly reducing personnel and property losses; at the same time, it can effectively cope with the complex industrial and mining environment of the mine, achieving long-term stable and efficient operation purpose, and realize flexible control of automatic fire extinguishing, manual fire extinguishing and emergency start-up fire extinguishing when extinguishing fire.
In addition, the mine car automatic fire extinguishing device/system can also effectively solve the fire extinguishing problems deep inside the coal mining vehicle as well as in small and confined spaces through customized design. It can be used exclusively for special vehicles and can truly and quickly determine the fire source point when a fire occurs. The real temperature can achieve the ultimate goal of accurate detection and accurate fire extinguishing.
The development and application of mine car automatic fire extinguishing systems/devices deeply integrates Internet of Things monitoring technology and intelligent fire extinguishing technology, integrating automatic vehicle fire detection, early fire warning and automatic fire extinguishing, achieving real-time tracing of vehicle fires, efficient fire extinguishing, Safety control can truly solve the problem of spontaneous vehicle fires.
