Production safety is the key to the efficient and stable development of coal mines and non-coal mining enterprises. With the increase in mining intensity and mining depth, especially the coupling and superposition of various disasters, coal mine safety production is facing increasing risks and pressures. Moreover, mining vehicles such as articulated mine cars, mining trucks, carriers, scrapers, flatbed trucks, rock drilling rigs, wet spray trolleys, and explosive trucks are widely used. Vehicle fire safety management is difficult, and fires are highly sudden. , high destructive power, and difficult to put out fires, there is an urgent need for intelligent vehicle automatic fire extinguishing devices to strengthen protection.
The development and application of mine car automatic fire extinguishing systems/devices can effectively realize fully automatic and unmanned fire safety protection for open-pit coal mining vehicles and underground mining vehicles. Mainly manifested in the following aspects:
1. Real-time monitoring of fires in flammable spaces can be achieved by reasonably distributing the appropriate number and location of fire source detectors according to the characteristics and size of the fire in the protection area, and different source detectors can be used according to the different characteristics of different protection areas. The temperature setting can effectively improve the accuracy of fire detection and achieve rapid detection of early stage fires.
2. The system uses Internet of Things technology to achieve purely mechanical linkage protection for each component of the system without human participation. When the fire source detector captures an abnormal fire signal, it will automatically trigger the fire extinguishing device and push water-based and other fire extinguishing agents through the agent. The refined spray from the pipeline to the nozzle achieves the purpose of fast and accurate fire extinguishing.
At the same time, the internal components of the mine car automatic fire extinguishing system: detection device, transmission device, control device, alarm device and fire extinguishing device are all made of stainless steel, which effectively enhances the stable safety performance of the fire extinguishing device. The starting method adopts a passive and non-electrified design, which simplifies the internal structure, makes the structure more compact, and takes up less space. It can be widely used to extinguish fires in compact and confined spaces such as mine cars. At the same time, high-efficiency water-based fire extinguishing agents are used, coupled with fine spray fire extinguishing technology, which can achieve the purpose of efficient fire extinguishing and resistance to re-ignition through rapid cooling and suffocation extinguishing, and effectively ensure the safety of vehicles and personnel after the fire is extinguished.
Mine car automatic fire extinguishing systems/devices can not only effectively improve the fire detection and fire emergency response capabilities of mining vehicles and mechanical equipment, but also grasp the best fire extinguishing opportunities and firmly control and eliminate fires through early proactive prevention. In the embryonic stage, it can reduce the probability of fire accidents, effectively ensure the smooth progress of mine production, and create a safer and more stable operating environment.
