According to the geographical distribution location and mining needs of mining enterprises' mineral resources, coal mining vehicles can be divided into open-pit coal mining vehicles and underground mining vehicles. Due to the different application environments and places, in terms of fire safety protection, the automatic fire extinguishing system of coal mining vehicles also proposes different fire extinguishing solutions: electronic automatic fire extinguishing devices for open-pit mining vehicles and special mechanical automatic fire extinguishing devices for underground mining vehicles, which provide the best service for mines. Vehicle fire protection provides a comprehensive, accurate and efficient fire safety defense mechanism.
In addition to the different application environments between open-pit mine cars and underground mine cars, in terms of fire protection, explosive situations should also be considered for underground mine cars. The air in most underground mines is thin, and toxic and harmful gases such as coal dust and gas are ubiquitous. Once a fire occurs, it will not only easily cause an explosion. Moreover, the underground space is small and it is difficult for people to escape. Therefore, in terms of fire protection, it not only needs to have automatic fire extinguishing performance, but also has the characteristics of no electricity and high efficiency to achieve safe fire extinguishing in an unmanned and no electricity environment.
The electronic automatic fire extinguishing device for open-pit mining vehicles is mainly composed of a chemical bottle set, a 2K fire source detector, a chemical pipeline, a detection line, a control unit, a battery life module, a nozzle and an alarm. Fire detection technology, signal analysis and conversion technology, early warning technology and sprinkler fire extinguishing technology are used to realize remote real-time monitoring and fire extinguishing of mine car fires. When a fire occurs in the vehicle, early warning can be provided through sound and light or SMS notification, and at the same time Issue fire extinguishing instructions to achieve rapid fire extinguishing.
The special mechanical automatic fire extinguishing device for underground mine cars is mainly composed of a chemical bottle group, a main chemical pipeline, a chemical branch pipeline, a mechanical fire source detector, a special sprinkler head, a manual starter, etc. When a fire breaks out in a vehicle, the fire source detector can automatically trigger and start the fire extinguishing device through mechanical action, and spray perfluorohexanone, water-based and other fire extinguishing agents to complete the fire extinguishing process.
Whether it is a mechanical automatic fire extinguishing device or an electronic automatic fire extinguishing device, their core purpose is to quickly and effectively put out the fire when a fire occurs in the vehicle, effectively ensuring the safety of the vehicle and people. Therefore, when selecting vehicle fire extinguishing devices, customized designs of different fire extinguishing devices can be carried out according to the vehicle operating environment and actual fire extinguishing needs to ensure safe, efficient and stable fire extinguishing.
