Description

Fire extinguishing method for remote fire control Technical Field The invention relates to the technical field of fire control, in particular to a fire extinguishing method for remote fire control. Background The earth environment condition cause anxiety is important for improving natural environment, protecting forest resources and ensuring ecological value and economic value of forests. However, annual worldwide forest fires frequently occur, and forest fire extinguishment is a problem which is difficult to solve. The burning of forest fires on forests, the damage to the environment, and the unestimated economic losses caused by fire are all quite serious. Fire has become the most painful catastrophic problem for people worldwide, especially with very powerful destructive fires. Forest fires are complex in fire, particularly cliff fires and other fires, and due to dangerous terrain, personnel are difficult to quickly approach and even cannot approach, the fire cannot be suppressed in the first time, the fire is easy to spread, the fire is further easy to expand, and great difficulty is brought to rescue work. The traditional fire extinguishing tool is difficult to realize remote accurate fire extinguishment, and therefore, the remote electromagnetic gun fire extinguishing vehicle is provided, and the fire extinguishing gun vehicle can perform remote forest fire extinguishing work aiming at fires which cannot be contacted by personnel. When a forest fire occurs, a professional fire fighter drives the fire-extinguishing gun car into a fire place. Under the unified dispatch of commander, carry out the adjustment of putting out a fire gun carriage and loading, then fire extinguishing bomb is launched towards the conflagration district. Thus, the remote fire extinguishment can be realized under the condition of avoiding casualties. And the fire-extinguishing gun gets rid of the requirement on water source. The burning of forest fires on forests, the damage to the environment, and the unestimated economic losses caused by fire are all quite serious. Fire has become the most painful catastrophic problem for people worldwide, especially with very powerful destructive fires. Forest fires are complex in fire, particularly cliff fires and other fires, and due to dangerous terrain, personnel are difficult to quickly approach and even cannot approach, the fire cannot be suppressed in the first time, the fire is easy to spread, the fire is further easy to expand, and great difficulty is brought to rescue work.
