The automatic fire extinguishing device for underground mine cars in coal mines is a fire safety equipment specially designed for underground mine cars in coal mines. It adopts new sensing technology and extinguishing measures, aiming to promptly detect and extinguish fires that may occur inside the mine car to protect personnel life safety and coal mine property.
The device usually consists of the following main components:
1. Flame/smoke detector: Through the detector installed in the mine car, it can monitor whether there is flame or smoke in the mine car in real time. Once an abnormality is detected, the detector will send out a signal to trigger subsequent fire-extinguishing measures.
2. Fire suppressor system: This system includes fire extinguishers and sprinkler heads. Select the appropriate fire extinguishing agent according to the fire level and type of mine car. When the detector triggers the alarm signal, the sprinkler head will release the fire extinguishing agent to form fire extinguishing mist in the mine car to suppress and extinguish the flame.
3. Controller and alarm system: The controller is the center of the device and is responsible for receiving and processing signals from the detector and triggering corresponding fire-extinguishing operations. At the same time, it can also send fire alarms to miners through sound and light alarms or other warning devices, reminding them to take emergency escape measures.
The automatic fire extinguishing device for underground mine cars in coal mines has the following application characteristics:
1. Automatic sensing: The device uses multiple detection technologies to monitor the internal environment of the mine car in real time, such as temperature, smoke, gas concentration and other parameters. Once an abnormality is detected, the fire extinguishing procedure will be started immediately.
2. Quick response: The device can quickly sense the source of the fire and initiate extinguishing measures, greatly reducing the time for the fire to spread and reducing losses and risks.
3. Efficient fire extinguishing: The device is equipped with efficient fire extinguishing agents, which can quickly and effectively extinguish the fire source and prevent the fire from spreading further.
Flexible arrangement: The nozzles are reasonably arranged according to the structure and layout of the mine car to ensure that the entire car can be covered quickly and evenly, providing comprehensive fire-extinguishing protection.
4. Intelligent monitoring and alarm: The device has an intelligent monitoring and alarm system. Once a fire occurs, warning information will be sent to miners in a timely manner through sound and light alarms, linkage control rooms, etc., reminding them to take escape and fire-fighting measures.
5. Strong reliability: The device has been strictly designed and tested and has stable and reliable performance. It can work normally in harsh underground environments and ensure the safe operation of underground mine cars in coal mines.
6. Regular maintenance: In order to ensure the continued reliability of the device, regular maintenance work is required, including checking sensors, replenishing fire extinguishing agents, cleaning nozzles, etc., to ensure that it can work normally in an emergency.
The application of fully automatic fire-extinguishing devices for underground mine cars can greatly reduce vehicle fire losses and improve the fire safety level and fire-extinguishing capabilities of heavy-duty vehicles, underground transport vehicles, dump vehicles and rotating mechanical vehicles. It is currently a commonly used automotive intelligent fire-extinguishing product.
