In the wave of intelligent and mechanized transformation in mining, industrial and mining vehicles such as loaders, excavators, loaders, and dump trucks are the core production equipment, and their safety directly affects the efficiency of mining operations and the safety of personnel. However, in complex industrial and mining environments such as high temperature, high humidity, dust, and corrosive gases, coupled with hidden dangers such as high engine load operation, aging electrical circuits, and high temperature in hydraulic systems, mine car fires have become the "number one killer" threatening mine safety. Therefore, improving the fire safety performance of industrial and mining vehicles has become an urgent need for mining enterprises to achieve safe production and efficient operation. The emergence of the automatic fire extinguishing system/device for Jiutong Changsheng industrial and mining vehicles provides an innovative and effective solution to this problem.

The causes of "invisible bomb" vehicle fires under complex working conditions are diverse: prolonged high load operation of the engine compartment can lead to heat accumulation, and a malfunction in the cooling system may cause spontaneous combustion; Aging electrical circuits and insulation damage can easily generate electrical sparks, igniting surrounding combustibles; Excessive oil temperature and pipeline leakage in the hydraulic system may result in oil mist combustion; Sparks generated by friction between vehicles and minerals may also ignite flammable materials. In addition, the interior space of the mining car is narrow, and the initial concealment of the fire is strong, making it difficult for manual inspection to detect. Once the fire spreads, it often causes the entire vehicle to be scrapped or even triggers a chain explosion.

The automatic fire extinguishing system/device for industrial and mining vehicles has built a "monitoring warning fire extinguishing" full chain protection system by integrating real-time fire detection, accurate fire analysis, efficient fire extinguishing protection, and intelligent high-end customization technologies.

The system adopts multiple types of sensors such as mechanical temperature detectors, K-type detectors, and linear detectors, covering key parts such as the engine compartment, electrical cabinet, battery pack, hydraulic oil tank, etc., forming a dense detection network. And through customized layout, the number and position of detectors can be adjusted according to the structure of the mining car to ensure that every corner is under monitoring, thereby achieving early real-time monitoring of early-stage fires.

Once a fire signal is detected, the automatic fire extinguishing system will immediately activate an efficient fire extinguishing program. The system quickly determines the size and area of the fire based on preset fire extinguishing strategies and intelligent algorithms. Through carefully designed nozzle layout, multiple nozzles and angles are simultaneously sprayed to form a comprehensive fire extinguishing agent coverage network. The nozzle adopts special atomization technology, which can evenly and finely spray the fire extinguishing agent to the ignition point, allowing it to quickly penetrate into the core of the fire source, rapidly reduce the temperature and isolate oxygen, thus achieving effective control and extinguishing of the fire in just a few seconds. Whether it is a solid fire, liquid fire, or electrical fire, the system can select suitable fire extinguishing agents according to different types of fires, such as new water-based fire extinguishing agents, ultra-fine dry powder fire extinguishing agents, or perfluorohexane fire extinguishing agents, to ensure maximum fire extinguishing effect. Compared with traditional fire extinguishing methods, the automatic fire extinguishing system for industrial and mining vehicles has faster extinguishing speed and higher efficiency, which can greatly reduce the losses caused by fires.

However, the harsh working environment of mines is beyond imagination. Open pit mining cars face challenges such as high temperature exposure, strong winds and dust, and bumpy roads, while underground mining cars need to operate in narrow spaces, high humidity, high gas concentration, and strong electromagnetic interference environments. The automatic fire extinguishing system for industrial and mining vehicles fully considers these harsh working conditions in the design and manufacturing process, and adopts a series of special technologies and materials to ensure the stable and reliable operation of the system. The shell of the system is made of high-strength and corrosion-resistant special alloy material, which can resist high temperature, corrosion, and mechanical impact; The line connection adopts sealing and reinforcement technology to prevent dust and water vapor from entering and causing short circuit faults. In addition, the system also has strong anti-interference ability, which can accurately detect fires and execute firefighting instructions in complex electromagnetic environments without being affected by external interference.

It can be seen that the promotion and application of automatic fire extinguishing devices/systems for Jiutong Changsheng industrial and mining vehicles marks a historic leap from "passive remediation" to "active defense" in mine firefighting. Under the guidance of the "Technology driven Security" strategy, this technology is becoming the core driving force for improving the quality and efficiency of mining safety. In the future, with the continuous innovation of technology, automatic fire extinguishing systems for industrial and mining vehicles will build a stronger safety barrier for the mining industry, helping mines move towards intelligence, greenness, and sustainability.
