Mining vehicles such as support trucks, frame transport trucks, hydraulic excavators, loaders, scrapers, and wide-body dump trucks are the key to ensuring the normal operation of mines. Currently, mining vehicles used for reloading and transporting are put into use in major mines. The volume of mining vehicles continues to increase, and the investment in this part of mining vehicles not only brings high yields to mining companies, but also adds difficulty to the fire safety management of mines, seriously restricting the healthy and orderly development of mining companies.
The mining vehicle automatic fire extinguishing system is specially developed and designed for the prevention and control of mining vehicle fires. The system adopts integrated prevention and control design, has a simple structure, is reliable and easy to use, and is currently a common choice for vehicle fire protection management in major mining companies. The system has good applicability. In addition to mining vehicles such as support trucks in the mining field, it is also suitable for heavy mobile equipment in other fields such as petroleum, engineering, ports, airports, agriculture and forestry, whether for early fire monitoring, detection, or This system/device can handle fire emergencies with ease.
The system is different from traditional fire extinguishing equipment in that it has better initiative and automation. It can fully automatically complete the entire process of fire prevention and control of heavy mobile equipment such as mining vehicles. Not only does it not require human intervention, but it is also responsive, fast and accurate. Also higher. The system can simultaneously protect single or multiple flammable spaces of mining vehicles through customized design, and actively and timely obtain and identify fire conditions through fire source detectors installed above the internal spaces of mining vehicles, and then realize the fire detection of mining vehicles. Prevention of early fires in vehicles and other heavy mobile equipment. When the detector determines that a fire has occurred, the system is automatically activated through the mechanical linkage of the components, and the fire extinguishing agent is released to extinguish the fire.
In addition to its high compatibility with mining vehicles, this system also has better flame retardant capabilities. The system successfully applies the latest fine spray technology and safe and environmentally friendly water-based fire extinguishing agents. The technology includes fine spray When the water-based fire extinguishing agent is discharged, the sprinkler head can release the fire extinguishing agent in the form of fine water mist less than 100 μm, thereby accelerating evaporation, taking away more heat in a shorter time, and reducing the temperature of the fire source. sudden drop. Secondly, as the water in the fire extinguishing agent evaporates, the main components of the agent will form crystals. When the temperature reaches 180°C, these crystals rapidly sublime and transform from solid to gaseous state, taking away a large amount of heat again, thereby quickly interrupting the combustion process. Effect.
The automatic fire extinguishing system for mining vehicles adopts a customizable structural design. The selection and materials of system components and agents take into account the structural characteristics, protection requirements and operating environment characteristics of mining vehicles. According to the size of the mining vehicle protection space, fire characteristics and protection requirements, it can be Differentially set the number and position of detectors, nozzles, and detector triggering temperature values; for the complex and harsh operating environments of mining vehicles such as high temperature, high corrosion, and high dust, the system chooses to use more durable stainless steel materials. So in general, this system/device is more suitable for the fire prevention and control needs of various types of heavy mobile equipment. It is also more worthy of being promoted and popularized by major mining companies.
