The following is a related information about the automatic fire extinguishing system for underground mining cars to achieve non electric passive self starting fire prevention and extinguishing operations: achieving non electric passive self starting fire prevention and extinguishing operations

The Jiutong Changsheng underground mine car automatic fire extinguishing system is a fire extinguishing device designed specifically for mining vehicles such as coal mines. The system adopts non electric passive self starting technology, which can detect and effectively contain the fire in the early stage of the fire, providing important support for the safety of mining operations and personnel protection. The following will provide a detailed introduction to the composition, working principle, and implementation of the automatic fire extinguishing system for underground mining cars, as well as how to achieve non electric passive self starting fire prevention and extinguishing operations.

1、 System composition

The automatic fire extinguishing system for underground mining cars mainly consists of key components such as medication bottles, control valves, detectors, nozzles, and pipelines. Among them, the chemical bottle stores the fire extinguishing agent, the control valve is responsible for controlling the release of the fire extinguishing agent, the detector is used to monitor the temperature in the vehicle protection space in real time, and the nozzle is responsible for releasing the fire extinguishing agent to the fire point.

2、 Working principle

The working principle of the automatic fire extinguishing system for underground mining cars is based on temperature detection and automatic triggering mechanism. When the temperature inside the vehicle protection space continues to rise and reaches the sensing temperature set by the detector, the system will automatically trigger, control the valve body to open, and release the fire extinguishing agent through the chemical pipeline to each nozzle, autonomously achieving the fire extinguishing process.

1. Temperature detection: The detector monitors the temperature inside the vehicle's protective space in real time. When the temperature reaches the preset sensing temperature, the system will immediately issue an alarm signal.

2. Automatic triggering: After receiving the alarm signal, the system will automatically trigger and control the valve body to quickly open, preparing to release the fire extinguishing agent.

3. Fire extinguishing agent release: The fire extinguishing agent is quickly transmitted to each nozzle through the chemical pipeline and released to the fire point, achieving rapid fire extinguishing.

3、 Non electric passive self starting fire prevention and extinguishing operation

The automatic fire extinguishing system for underground mining cars adopts non electric passive self starting technology, which avoids the power supply problems and electrical insecurity in the flammable environment of coal mines. The system is designed purely mechanically and can automatically detect, alarm, and extinguish fires without the need for power connection.

1. Passive design: The system adopts a passive and electrically free mechanical structure configuration, without the need to lay power lines, reducing redundant and complex circuit pipelines and lowering the system's risk.

2. Self starting mechanism: When the temperature in the vehicle's protective space reaches the sensing temperature set by the detector, the system will automatically trigger the fire extinguishing operation without manual intervention.

3. Fire extinguishing agent selection: The system can choose water-based, ultra-fine dry powder, perfluorohexane and other fire extinguishing agents according to customer needs and protective space characteristics to achieve the best fire extinguishing effect.

4、 System features and advantages

1. Simple structure and reliable use: The system has three modes of automatic start, manual start, and mechanical emergency start, with a simple structure and reliable use.

2. Fast extinguishing speed and high extinguishing efficiency: The use of fire detectors can effectively perceive and detect fires, achieving rapid detection, response, and extinguishing when a fire occurs.

3. Exquisite structure and small space occupation: The device has a high degree of integration and can be applied to narrow and complex spaces of vehicles. The installation location will not affect daily maintenance and driving.

4. Strong adaptability: The system can be widely used in coal mine vehicles, port machinery, airport vehicles, oilfield equipment, industrial and mining vehicles, etc. It can extinguish Class A, B, C, and E fires.

5、 Conclusion

The automatic fire extinguishing system for underground mining cars adopts non electric passive self starting technology, which realizes rapid detection and automatic fire extinguishing functions in the early stage of fires, providing important support for mining operation safety and personnel protection. The system has a simple structure, reliable use, fast fire extinguishing speed, high fire extinguishing efficiency, and strong adaptability, and can be widely applied to various types of mining vehicles.
