In order to effectively reduce the occurrence of mine vehicle fire accidents such as scrapers, loaders, trackless rubber-tyred vehicles, forklifts, and rock drilling rigs, improve the level of mine safety protection, and meet the actual fire-fighting needs of mining enterprises, the open-pit coal mine vehicle automatic fire extinguishing system/ The device emerged as a customized intelligent protective fire extinguishing equipment, which effectively solves the fire safety problems of underground mining vehicles and surface mining vehicles, and realizes real-time monitoring, efficient response and precise fire extinguishing of mine car fires.
The open pit coal mine vehicle automatic fire extinguishing system/device adopts integrated management and control, takes up little space, and does not require complex equipment. Instead, the fire source detector, agent pipeline, nozzle and detection line need to be installed according to the actual protection needs and the internal structure of the vehicle. That’s it, it not only effectively solves the problem of fire extinguishing in relatively closed and narrow spaces such as mine car engine rooms, but also can accurately and effectively extinguish the fire source and eliminate the fire in the early stages in a timely manner.
System fire extinguishing principle:
The open pit coal mine vehicle automatic fire extinguishing system/device is a simple and highly reliable independent automatic fire extinguishing equipment that integrates fire detection, alarm and fire extinguishing. When the temperature in the protective area is abnormal and reaches the warning temperature set by the detector, the fire extinguishing device will automatically trigger and start, sending out an early fire warning signal. If the temperature in the protected area continues to rise to the operating temperature, the fire extinguishing device will automatically issue a fire extinguishing command, spray water-based fire extinguishing agents, and quickly and fully flood the protected area to accurately extinguish the fire to complete the fire extinguishing process.
At the same time, in the automatic fire extinguishing system/device of open-pit coal mine vehicles, the design and installation position of the sprinkler head are also crucial. The sprinkler head is generally installed above or diagonally above the protective area, and must be able to spray the fire extinguishing agent evenly inside the protective area to ensure that the fire extinguishing agent can cover the entire fire extinguishing area. In addition, the number and location of sprinkler heads must be reasonable so that they can be quickly activated and spray extinguishing agents when a fire occurs.
In addition, the automatic fire extinguishing system/device of open-pit coal mine vehicles also pays attention to humanized design. The system's startup method is simple and easy to understand, making it easy for operators to quickly master how to use it. It also has multiple fire extinguishing methods such as automatic startup, manual startup, and mechanical emergency startup. Moreover, the system also has a self-test function, which can detect the operating status of the equipment in real time to ensure the safe and normal operation of the fire extinguishing device, effectively guarantee the safety of mine operations, and bring stable and reliable economic benefits to the mine.
