In order to effectively solve the fire protection needs of coal mine vehicle fire extinguishing in terms of professionalism, safety, efficiency and environmental protection, the underground mine vehicle automatic fire extinguishing system and the coal mining vehicle automatic fire extinguishing system are realized by installing fire source detectors in each flammable space. Real-time monitoring and detection of flammable space fires, in order to respond quickly to activate and start fire extinguishing devices as soon as a fire occurs, release water-based fire extinguishing agents, quickly prevent and control fires, and achieve all-round detection and no dead ends fire extinguishing. It not only realizes the autonomy, intelligence and unmanned operation of mine car fire extinguishing, but also eliminates the need to connect the power supply, effectively improves the safety performance of the vehicle and greatly reduces the risk of property and personnel safety in fire accidents.
The underground environment of coal mines is complex, with many tunnels and small underground spaces. Mine cars shuttle continuously around. The complex and changeable environment makes underground mine cars often exposed to external threats such as high corrosion, high temperature, toxic gases, and combustibles. Once a fire accident occurs, fire rescue work is often difficult due to the complex and narrow underground space in coal mines. Nowadays, with the rapid development of science and technology, the degree of intelligence, informatization and automation in the coal industry has been significantly improved. Coal mine fire safety construction is also gradually improving in the direction of intelligence to ensure the safety of workers and achieve safe and efficient production of coal mine vehicles.
The underground mine car automatic fire prevention and extinguishing system/device can realize the rapid detection of early fires through real-time and all-round temperature real-time monitoring in the early stages of coal mine vehicle fires. At the same time, the abnormal temperature signal is detected in time and the automatic fire extinguishing device is controlled to extinguish the fire source, achieving "extremely fast fire extinguishing", extinguishing the fire in the bud, effectively blocking the spread of the fire, and realizing fully automatic unattended fire extinguishing.
Advantages of coal mine vehicle automatic fire extinguishing system/device:
1. Change the traditional fire extinguishing model and use water-based fire extinguishing agents to quickly extinguish and suppress fire re-ignition through cooling and suffocation.
2. The purely mechanical structure trigger eliminates the unsafety of electrification and provides safe and stable fire-extinguishing equipment for underground mine cars.
3. Low maintenance cost, no complicated maintenance process required, effectively saving manpower, material and financial resources.
4. The response time is short, the fire is extinguished quickly, and the water-based fire extinguishing agent can be fully covered evenly without dead ends.
5. After the fire is extinguished, there will be no damage to the vehicle's internal equipment, and it is highly safe and environmentally friendly, making it easy to resume production quickly after disasters.
It can be seen that the underground mine car automatic fire extinguishing system/device integrates fire detection and fire extinguishing, achieving unmanned control and autonomous fire extinguishing of vehicle fires, truly realizing the intelligentization of mining vehicle fire extinguishing, and effectively ensuring mine production. Safe and stable development.
