Due to the harsh environment of the mine, the conditions of high temperature, high humidity and high corrosion not only affect the work efficiency and health of workers, but also destroy the key components of mining vehicles, resulting in potential safety hazards and fire hazards. Through the automatic fire extinguishing system for underground vehicles, the fire situation in the high-fire area is monitored in real time, and corresponding countermeasures are actively taken to firmly control the fire safety of coal mine vehicles.
Operation mechanism of automatic fire extinguishing system for underground vehicles:
1.Fire monitoring.
Through the mechanical temperature detector, the temperature change and fire detection of the engine compartment, fuel tank, battery compartment, tires and other areas of the underground vehicle are carried out 24 hours a day, and the equipment will not produce human fatigue and slack fire monitoring, and truly realize the uninterrupted monitoring of regional fire.
2.Fire warning.
When the detector detects a dangerous fire in the area, the alarm device will be activated at the same time, and the surrounding staff will be notified in an emergency to deal with or evacuate in a timely and reasonable manner.
3.Fire extinguishing sprinklers.
When the fire has reached the need to extinguish the fire, the staff withdraws from the fire scene, and leaves the fire to the underground vehicle with the automatic fire extinguishing system for processing, and the fire extinguishing device is automatically started immediately, releasing an appropriate amount of fire extinguishing agent until the flame is fully covered, and the surrounding parts and equipment are covered with a dense anti-flame film, which effectively prevents re-ignition.
Application characteristics of automatic fire extinguishing system for underground vehicles:
1.Smart automatic.
The automatic fire extinguishing system for underground vehicles adopts advanced fire source detectors and fire extinguishing settings, makes full use of the attributes of the device for automatic management, and realizes automatic fire prevention and control under unattended conditions.
2.Passive and powerless.
The system uses a passive and non-electric system, which does not require power support, which saves the cost of use, and also reduces the danger of power runaway due to the reduction of laying power supply circuits.
3.Safe and stable.
Through the use of austenitic stainless steel materials or electroplating treatment for the key parts of the underground vehicle automatic fire extinguishing system, the line pipeline is protected by flame retardant and wear-resistant protective gear, which has higher safety performance, prolongs the service life of the equipment, and provides fire extinguishing guarantee more stably.
