In view of the fire problems of mining vehicles such as rock drilling rigs, support trucks, scrapers, monorail cranes, explosive trucks, explosion-proof command vehicles, flatbed transport trucks, trackless rubber-tyred trucks, etc., the mine truck automatic fire extinguishing system developed is an advanced , Intelligent vehicle-mounted fully automatic fire extinguishing device. The system can be installed inside flammable areas such as vehicle engine compartments. It does not require frequent maintenance and does not hinder the normal operation and daily maintenance of the vehicle. After a vehicle catches fire, the fire extinguishing system can be instantly triggered by the temperature sensing device to quickly release water-based, Fire extinguishing agents such as perfluorohexanone can realize full submersion and efficient fire extinguishing, and have become an effective fire extinguishing method for mining vehicle fire protection in mining companies.
As the main force of mining production, mine cars have the characteristics of small internal space, complex oil and electricity lines, long running time, and inconvenient daily inspections. Once a fire occurs, it can only be extinguished by traditional and inefficient fire extinguishing methods such as portable fire extinguishers equipped on the vehicles. When extinguishing fires, it is difficult to control the fire accurately and effectively, and fires are highly destructive. Therefore, it is necessary to equip the mine car with an automatic fire extinguishing system.
The design and development of the mine car automatic fire extinguishing system meets the principle of "extinguishing early, small, and early stage fires for mine vehicles and heavy machinery equipment". At the same time, customized fire extinguishing solutions are used to achieve its wide applicability. At the same time, one-to-one professional customization is carried out to effectively improve its accuracy: based on comprehensive factors such as the size of the protected area, structural characteristics, and actual fire extinguishing needs, the device startup method, number of detectors, number of nozzles, and pipeline routes are The paving requires precise design and layout to achieve real-time, all-round, and accurate effective protection against vehicle fires, and improve vehicle fire emergency response performance and mining vehicle fire safety factor.
Innovative applications of mine car automatic fire extinguishing systems/devices:
1. Mechanical passive fire extinguishing can not only solve the dependence on power supply, but also enhance system safety performance and reduce enterprise operating costs.
2. It adopts a pressureless single pipeline structure. The pipeline is in a pressureless state under normal conditions and maintains pressure at the moment of startup, making it safer.
3. Fine spray fire extinguishing technology can effectively improve the agent delivery efficiency, expand the agent coverage area, and effectively improve the system's fire extinguishing performance.
4. High-efficiency water-based fire extinguishing agent can quickly suppress and interrupt the fire through physical cooling and rapid heat absorption, and achieve safe, non-destructive and efficient fire extinguishing.
The development and application of mine car automatic fire extinguishing systems/devices have effectively realized the early stage of accurate detection, efficient response, independent alarm and rapid fire extinguishing of mining vehicle fires in coal mines, gold mines, iron mines, etc., effectively ensuring the property and life safety of mining companies and personnel, and realizing It marks the direction of new fire extinguishing in smart and unmanned mines, and is an important equipment for the development of smart mines in the future.
