Based on the flammable and explosive complex environment underground in coal mines, in order to effectively ensure the fire safety of underground mine vehicles such as rock drilling rigs, scrapers, trackless rubber-tired vehicles, flatbed transport vehicles, tunnel boring machines, and anchor trolleys, rock drilling rigs The automatic fire extinguishing system adopts mechanical non-electrical fire extinguishing technology to realize real-time monitoring of vehicle fires and non-electrical fire extinguishing, effectively ensuring the safe and stable operation of underground vehicles in coal mines, and solving the long-standing problem of mining vehicle fire extinguishing that has plagued mining companies.
As the degree of mechanization of mines continues to increase, rock drilling rigs and other mine vehicles are increasingly invested and used in mines. While greatly improving mine production efficiency and increasing production capacity, the fire safety issues of vehicles have also become a problem that troubles the stability of mining companies. development problems. The long-term and high-intensity operation of mining cars, coupled with the erosion of complex and harsh environments, coal dust accumulation, line aging, fuel leakage, sustained high temperatures and other problems have led to increasingly prominent vehicle fire accidents, which poses a serious threat to the property and life safety of mining companies and personnel. serious threat. Therefore, fire extinguishing products with high performance, intelligence and stability are of great significance in preventing and handling mine car fire accidents.
As a special fire extinguishing device for coal mining vehicles, the automatic fire extinguishing system/device of rock drilling rig overcomes the limitations and lag of traditional fire extinguishing in the past. Not only has it made technical improvements and enhancements in fire-extinguishing performance, but it has also been upgraded in terms of stability, allowing it to operate stably and reliably in the complex and harsh environments of mines, maintaining good detection and fire-extinguishing performance.
1. Fire extinguishing performance
On the one hand, it uses extremely fast fire detection technology and utilizes the sensitivity of mechanical temperature detectors to the fire source temperature to achieve very early detection of vehicle fires, effectively shortening vehicle fire detection and response times and improving its accuracy; on the other hand Using pipe network transportation + fine spray technology, while improving its transportation efficiency, it can achieve partial or full submersion fire extinguishing, making the fire extinguishing speed faster and more accurate.
2. Stability
Combined with the complex environment of high temperature, high humidity and high corrosion in mines, the use of all stainless steel materials effectively improves the sealing and stability of the fire extinguishing device and effectively extends the service life of the device. At the same time, in view of the harsh environment of high vibration in mines, shock-absorbing devices are used to fix the medicine bottles, and fire-proof and flame-retardant sleeves and nylon sheaths are worn on the pipelines and lines to make them more stable and durable.
