Mining vehicles such as rock drilling rigs, support trucks, wide-body dump trucks, hydraulic excavators, loaders, scrapers, etc. are important mechanical equipment for mining enterprises such as coal mines and gold mines. They play a role in mining and transporting ore, coal, The important role of materials and equipment can reduce the labor intensity of workers and improve work efficiency. During its long-term operation, local flammable spaces such as vehicle engine compartments, vehicle-mounted distribution boxes, battery boxes, fuel tanks, tires, etc. There are major fire safety hazards.
1. Application background of mine car automatic fire extinguishing system
The working environment of mining vehicles is complex and changeable. Under heavy work intensity and continuous operation for a long time, there are great fire safety hazards. Once vehicle fire safety problems occur, it will affect vehicle safety, personnel safety and the normal operation of mining enterprises. There is a greater threat. However, traditional vehicle fire extinguishers are highly dependent on manual labor and cannot realize automatic fire detection and automatic fire extinguishing functions under unattended conditions. Moreover, due to the limitations of the fire extinguisher's fire extinguishing agent injection pipeline When performing fire control, it is difficult to effectively release fire extinguishing agents into the protective space accurately and comprehensively, resulting in poor fire prevention and control effects and serious impact on surrounding facilities and mining companies.
2. Fire control solutions for mining vehicles
The mine car automatic fire extinguishing system uses fire detection technology, signal transmission analysis technology, early warning technology and fire extinguishing agent precision spray technology to change the traditional fire extinguishing method and achieve precise and rapid fire control functions. The fire control process is as follows:
1. Use secondary K-type detectors, flame detectors, infrared thermal imaging and other fire detection equipment to install them above or diagonally above the protective space on the premise of ensuring that they affect the normal operation of the vehicle and do not affect normal vehicle maintenance and inspection. All-round and real-time monitoring of fire conditions in the mine car's protective space can be achieved without personnel participation.
2. As the information processing center of the mine car's automatic fire extinguishing system, the control unit can not only receive fire information from the protective space, but also perform calculations based on its own algorithm to detect abnormal fire signals in a timely manner and issue corresponding early warnings and fire extinguishing actions. instruction.
3. The special release pipeline for fire extinguishing agents plays the role of fixed-point transportation of the agent. Coupled with the application of special sprinklers for fire extinguishing agents, the spray accuracy and spraying effect of fire extinguishing agents can be greatly enhanced, and the purpose of rapid fire control is achieved.
