Mine car automatic fire extinguishing devices and mining vehicle automatic fire extinguishing systems are used as rock drilling rigs, articulated mine cars, wide-body dump trucks, explosion-proof trackless rubber-tyred trucks, air compressors, shearers, coal mine underground monorail cranes, shield machines, hydraulic Commonly used fire extinguishing products for mining vehicles such as brackets have the characteristics of compact structure, convenient installation, and small space occupation. They can realize automatic detection, early warning and fire extinguishing of fires in flammable areas such as vehicle engine rooms, and promote intelligent fire protection and technology of mining vehicles. New development of fully automated fire extinguishing in firefighting.
Most roads in mining areas are generally narrow, bumpy, with steep slopes and many turns. Mining vehicles often operate in harsh and complex environments such as high temperature and high corrosion, which can easily cause short circuits, fuel leaks, vehicle battery aging and other problems, posing greater safety risks. This will cause fire hazards, cause huge economic losses and affect the normal production order of the mine. The installation and application of mine car automatic fire extinguishing systems/devices can effectively detect fires in flammable spaces and carry out efficient fire extinguishing.
Features of the mining vehicle automatic fire extinguishing system/device:
1. The fire extinguishing agent bottle set adopts internal pressure storage, the pressure is between 1.5-2Mpa (safety pressure), takes up little space and has high safety performance.
2. The probe temperatures of different risk areas can be designed separately, and detectors of different specifications can be installed in areas with higher normal operating temperatures and areas with lower temperatures in the vehicle to prevent the occurrence of no-spray situations.
3. The installation position of the probe should be installed above the flammable space. Multiple detectors should be installed according to the size of the space. If any one of the detectors detects an abnormal temperature, the fire extinguishing system can be activated.
4. The chemical pipeline and detection pipeline need to be protected to be wear-resistant and flame-retardant.
Advantages of mining vehicle automatic fire extinguishing systems/devices:
1. Temperature-sensing automatic start: The automatic fire extinguishing device of mining vehicles adopts fire detection technology to realize sensitive detection of fire temperatures in protective areas such as vehicle engine compartments and vehicle-mounted distribution boxes. When the set sensing temperature is reached, it can automatically start fire extinguishing. The device is used to extinguish fires without the need for personnel to participate in the entire process.
2. Exquisite structure and small space occupation: The mine car automatic fire extinguishing system adopts electroless fire extinguishing technology and a single pipeline structure. It does not require power supply during installation, does not damage the car body structure and lines, fits its own structure, can operate independently, and has stable performance.
3. Pipe network spray fire extinguishing technology: The use of special agent delivery pipelines can achieve accurate and rapid delivery of fire extinguishing agents, improving the efficiency and utilization of fire extinguishing agents. In addition, special customized nozzles further ensure that the fire extinguishing agents are more uniform and refined. Full coverage spray to expand coverage. Improve fire extinguishing efficiency and achieve local total submersion fire extinguishing.
4. Long running time and low maintenance cost: The automatic fire extinguishing system of mining vehicles performs anti-corrosion, shock absorption, wear resistance and other treatments according to the working conditions of the vehicle to ensure the operating time of the fire extinguishing device to the greatest extent. At the same time, the fire extinguishing device is maintained during the maintenance process. There is no need to disassemble pipelines, accessories, etc., and the operating status of the automatic fire extinguishing device of the mining vehicle can be easily understood through the self-test function.
