Mining vehicles such as rock drilling rigs, shearers, explosive trucks, concrete mixer trucks, and articulated mine trucks are important auxiliary transportation equipment in mines and have an important impact on the production, transportation, and transfer of mining vehicles such as coal mines. Mine car automatic fire extinguishing systems, coal mining vehicle engine room special fire extinguishing devices, etc., as customized fire extinguishing equipment for mining vehicles, can provide precise protection for flammable spaces such as the vehicle engine room, distribution box, and battery room, and build an unmanned, Intelligent, efficient, all-round refined mine car fire service system.
Common causes of fires in mining vehicles:
1. Electrical failure: Internal spaces such as the engine room of mining vehicles have many and intricate circuits. Under the high temperature and high corrosion environment of the mine, it is easy to cause electrical system failures, such as wire aging, short circuit and other problems, which can easily lead to fire accidents. .
2. Oil circuit failure: The hydraulic system of mining vehicles uses a large amount of hydraulic oil. If the oil pipe ruptures or the seals age during operation, it will cause oil leakage, posing serious fire safety hazards.
3. Accumulation of combustibles: During the operation of mining vehicles, a large amount of accumulated combustibles such as coal dust, dust, and oil will be produced. Moreover, long-term operation of the vehicle will cause the engine compartment, gearbox, and distribution box to continue to be at high temperatures. , thereby igniting combustible materials and causing fire.
The mine car automatic fire extinguishing system can conduct real-time and continuous fire detection of fires in the protection area through mechanical temperature detectors installed in flammable spaces such as mining vehicle engine rooms, vehicle distribution boxes, battery boxes, and fuel tanks. . When a fire occurs in the protected area, the system will automatically activate the fire extinguishing device to carry out fire warning and automatic fire extinguishing actions without human intervention. At this time, fire extinguishing agents such as perfluorohexanone and water-based agents will be accurately released to the approach area through special agent delivery pipelines to achieve the purpose of fast, accurate and efficient fire extinguishing.
In addition, the mine car automatic fire extinguishing device/system has unparalleled technical advantages over traditional firefighting in terms of configuration, mainly in:
1. Pharmacy bottle set: Made of austenitic stainless steel, it is corrosion-resistant, high-temperature resistant and has strong sealing properties. It can easily cope with the harsh environment of the mine. At the same time, strong hoops and shock-absorbing rubber strips are used during installation to improve its seismic performance, especially for use Firefighting in mining vehicles.
2. Mechanical fire source detector: It can be customized and installed according to the size of the protection area and fire characteristics, and the trigger temperature can be set differentially to detect early fires more quickly and accurately.
3. Self-starting device: Through the mechanical linkage of system components, it can automatically respond to start fire extinguishing as soon as a fire occurs, shorten fire extinguishing time, improve fire extinguishing efficiency, and solve the problem of unattended fire extinguishing.
4. Fine nozzles: The use of customized special mist fine nozzles enables water-based and perfluorohexanone fire extinguishing agents to spray out fine water mist quickly, effectively expanding the coverage area, making the fire extinguishing agent release more quickly, covering the fire source, etc. Evenly, the fire extinguishing effect is more significant.
