Today, with the rapid development of social economy, fire safety protection and emergency fire rescue have become the focus of widespread attention from all walks of life in mining, ports, steel plants and other fields. The research and development of underground/open-pit mine car automatic fire extinguishing systems (devices) breaks the restrictions of industry, region and use. With its unique fire prevention and extinguishing performance and high-end fire extinguishing technology, it is widely used in mining vehicles, port flow machines, oil field vehicles and engineering machinery and equipment. It has played an important role in fire safety construction in other fields and has been widely recognized and favored by many mining enterprises.
Mining vehicles such as articulated mine cars, scrapers, loaders, hydraulic excavators, shearers, monorail cranes, wet spray trolleys and shovel trucks are important components of mine production and are manufactured during production operations. Frequent movements, vehicle engine compartment, turbocharger, gearbox, etc. continue to be hot. In addition, affected by the complex working conditions of high temperature and high pressure, problems such as aging, rupture, short circuit and other problems of vehicle internal circuit equipment often occur, which can easily lead to vehicle fire accidents. Therefore, the fire safety protection of mine cars is urgent.
The underground/open-pit mine car automatic fire extinguishing system integrates automatic fire detection, early warning and fire extinguishing. Through real-time temperature sensing fire detection technology, it can realize real-time monitoring of fires in different environments of mining vehicles during the whole period. When a fire occurs, it can quickly , accurately detect the fire source and automatically activate the fire extinguishing device to effectively control the spread of fire, reduce the harm of fire to personnel and equipment, and achieve the purpose of rapid fire control and fire extinguishing.
The underground/open-pit mine car automatic fire extinguishing system has made technological innovations in traditional fire extinguishing technology, mainly in:
1. Adopt a customized fire-extinguishing design scheme that fits the internal structure of the vehicle, and install the fire source detector and sprinkler head directly inside the vehicle. This effectively solves the problem of fire-extinguishing in the small confined space inside the vehicle and at the same time achieves the goal of protecting the mine. All-weather, all-round, continuous fire monitoring for vehicle fires.
2. The use of unmanned temperature-sensing self-starting fire-extinguishing technology and water-based fine spray fire-extinguishing technology eliminates dependence on personnel. At the same time, the efficient fire-extinguishing performance of water-based fire extinguishing agents is used to quickly reduce the temperature in the protected space and improve the protection. Full-coverage fire extinguishing is carried out for regional fires, and combustion is quickly blocked through oxygen isolation and suffocation to achieve efficient fire extinguishing performance.
As an innovative and customized fire prevention and extinguishing equipment, the underground/open-pit mine car automatic fire extinguishing system gives full play to its own performance advantages. It not only has the characteristics of high detection accuracy, timely fire response, efficient and fast fire extinguishing, etc., but also complies with the requirements of mines without fire extinguishing. The development process of people, wisdom, and mechanization has achieved the coexistence of safety and efficiency, effectively ensuring fire safety in various fields such as mines, ports, oil fields, and steel plants.
