As a mining vehicle automatic fire extinguishing system for many mining vehicle fire prevention and control, it uses a special mechanical fire source detector as a detection device, integrating Internet of Things technology, sensing technology, alarm technology, control technology and sprinkler technology, and has essential It has the advantages of safety, corrosion resistance, and electromagnetic interference. It can continuously monitor fire conditions in single or multiple flammable areas. It is suitable for rock drilling rigs, scrapers, shearers, tunnel boring machines, road rollers, and mining dump trucks. , loaders, articulated mine cars and other mining vehicles provide high-quality independent fire detection and fire extinguishing solutions.
Mining vehicles, as common mechanical equipment in mining, often cause fires due to contact with flammable and explosive materials and high-temperature environments during production and operation. Fire prevention and control has become a major problem for mining enterprises in Xinjiang, Shanxi and other areas. Let’s first understand the following flammable areas that cause fires and their causes:
1. Engine compartment: As the power source of the vehicle, the engine compartment is generally the hardest hit area by fires. When the vehicle continues to run, the engine will continue to be high-temperature. In addition, a large amount of fuel is required to provide power during operation. It is easy to cause a fire due to fuel leakage, circuit failure and other reasons, and the fire can easily spread.
2. Hydraulic system: The hydraulic system is an important part of vehicle operation, but it is also a potential source of fire hazard. The hydraulic oil is flammable. Once the hydraulic pipeline leaks due to wear, aging and other reasons, it will easily cause spontaneous combustion and fire under the action of high temperature of the vehicle, causing a fire accident.
3. Electrical system: Due to the complex environment of high corrosion and high vibration in mines, the internal circuits of the vehicle are easily susceptible to degradation in insulation performance due to wear and aging. Coupled with the impact of high-temperature environments, it is easy to cause circuit short circuits and spontaneous combustion.
It can be seen that fires in mining vehicles are mainly concentrated in the engine room, hydraulic system, electrical system and other parts. Once a fire breaks out, with the participation of combustion-supporting substances such as coal dust and oil pollution, the fire will spread rapidly and easily cause heavy casualties and property losses. , so it is necessary to equip it with high-performance fire extinguishing devices.
Mining vehicle automatic fire extinguishing system/device functions:
1) The system can perform simultaneous prevention and control of fires in single or multiple protective spaces according to actual fire extinguishing needs. According to the fire characteristics of each protective space, the temperature of the temperature detector can be set differently. When the temperature in the detection area reaches the set temperature When on duty, the system automatically starts and sprays chemicals to extinguish the fire.
2) When the staff discovers the fire in advance and the temperature in the protection area does not reach the set threshold, the fire can be extinguished manually by pressing the manual start button.
3) The system has a fire early warning function. It can collect and analyze early fire information, notify personnel of the occurrence of fire through sound and light alarms, carry out defense and deployment in advance, and adopt active fire extinguishing mode to effectively reduce fire hazards.
The introduction of automatic fire extinguishing systems/systems for mining vehicles will provide mining enterprises with safer and more reliable production guarantees. In order to ensure the fire safety of mining vehicles and improve their fire emergency response performance, the installation of automatic fire extinguishing systems for mining vehicles has become the future development trend of smart fire protection in mines, thereby providing a solid guarantee for the safety and stability of mine production.
