With the continuous acceleration of mining development, the safety protection of mining vehicles has become an important issue that cannot be ignored. The engine compartment, as the power source of mining vehicles, has become the hardest hit area causing fire accidents in mining vehicles. The underground mine car automatic fire extinguishing system/device provides a solution to the problem of mine car engine room fires through professional one-to-one precise protection.
First, let’s analyze the fire factors in the engine compartment of mining vehicles:
1. The environment of the engine room of mining vehicles is complex, the internal space is closed and narrow, and there are a large number of electrical equipment and equipment. In addition, the mining environment is high vibration, high corrosion, flammable and explosive, etc., so the stability and stability of the fire extinguishing device are affected. There are strict requirements in terms of safety.
2. Fires in the engine compartment of mining vehicles are mostly caused by fires in oil lines, wiring, etc. Once a fire occurs, if it cannot be suppressed and prevented in time, the vehicle fire will spread rapidly and seriously endanger the lives of workers. Therefore, in terms of fire extinguishing efficiency, it is necessary to be able to quickly suppress and control the fire in a short period of time.
3. The engine rooms of mining vehicles are mostly confined spaces. It is difficult to detect a fire in time in the early stage. When discovered, it may be too late and the opportunity to extinguish the fire will be missed. In addition, traditional fire extinguishing requires opening the cabin cover to extinguish the fire, which will not only increase oxygen intake and fuel the fire, but also pose a serious threat to fire fighters who are close to the fire. Therefore, traditional fire extinguishing methods can no longer meet their fire extinguishing needs.
Innovative advantages of underground mine car automatic fire extinguishing system:
1. Using fixed-point fire detection technology, non-contact, all-round, all-weather real-time collection of fire signals for vehicle fires can be achieved by distributing fire source detectors in flammable spaces such as engine compartments and battery boxes, with detection capabilities It is timely, accurate and efficient, providing an accurate data source for the start-up of fire extinguishing devices.
2. In view of the problem of small space inside the engine compartment, a single pipeline structure is adopted and the pipe network spray fire extinguishing technology is used, which not only occupies a small space, but also effectively improves the efficiency of agent delivery, improves agent utilization, and thereby reduces operating costs.
3. In terms of fire extinguishing effectiveness, it is equipped with customized mist nozzles, which are distributed above or diagonally above the engine compartment. It can fully cover the fire and extinguish the fire, effectively eliminating potential fire hazards and three-dimensional fires.
4. It is equipped with automatic start, manual button start and mechanical emergency start. Operators can perform the fastest and most convenient operation according to the vehicle fire situation to achieve rapid fire extinguishing and effectively reduce fire losses.
In addition, the underground mine car automatic fire extinguishing device/system can also achieve precise protection of a single space fire or multiple flammable space fires by setting different temperatures of the detector according to the customer's actual fire extinguishing needs and mining vehicle fire characteristics. The joint protection can meet a variety of different fire-fighting needs and effectively solve the fire safety issues of special vehicles in different fields such as mines, ports, airports, petrochemicals, and agriculture.
