(2) water-based extinguishing agent is added.Before fire extinguishing, in extinguishing chemical case 3, add enough water-based extinguishing agents, be used for mixing pure water and put out a fire.
(3) pure water is added.In ventral water tank 4, fill pure water in advance, or flight utilizes the water drawing device of helicopter itself to draw water to the surface, water source satisfied the requirements.
(4) fire extinguishing.By regulating the flow of extinguishing chemical and pure water, after exit is by jet mixer 9 mixing, it is sprayed to scene of a fire fire extinguishing.
(5) judge to put out a fire to save life and property effect.If mountain fire does not put out, after carrying out (6) step, continue fire extinguishing；Otherwise, put out a fire to save life and property end.
(6) moisturizing.Moisturizing or fly to the surface, water source satisfied the requirements to draw water after helicopter landing.
Embodiment 2:Utilizing K-32 type helicopter made in Russia to carry out extinguishing operation, this helicopter adopts well-bucket to take the mode of water.In the present embodiment, the capacity of helicopter well-bucket 10 is 4.5 tons.Comprise the following steps:
(1) device improves.Existing helicopter well-bucket needs in bottom folding to realize water intaking and watering, it is impossible to add water-based extinguishing agent.As shown in Figure 2, helicopter well-bucket 10 in the present invention arranges an annular extinguishing chemical capsule 11 at well-bucket inwall, for being previously stored water-based extinguishing agent, the air bag that in annular extinguishing chemical capsule 11, a sheathed volume is suitable, can the extinguishing chemical extrusion in extinguishing chemical capsule 11 being mixed with water to helicopter well-bucket 10 by controlling the capacity of air bag, the bottom valve folding controlled above helicopter well-bucket 10 base again through pneumatic actuator is put out a fire to discharge extinguishing fluid.The capacity of extinguishing chemical capsule 11 can be joined 6-10 bucket pure water with full capsule extinguishing chemical and is advisable.Extinguishing chemical capsule 11 is provided with liquid-filling valve and multiple check valve, and air bag is provided with air bag intake valve and air bleeding valve.Pneumatic actuator and air bag intake valve control by the air pump on helicopter.In the present invention, the concrete structure of helicopter well-bucket 10 is referring to the patent No. existing structure that to be ZL201520369785X, patent name be " a kind of helicopter well-bucket adding water-based extinguishing agent ", and in this not go into detail.
(2) water-based extinguishing agent is added.Before fire extinguishing, in extinguishing chemical capsule, add enough water-based extinguishing agents, be used for mixing pure water and put out a fire.
(3) pure water is added.Helicopter carries the well-bucket equipped with water-based extinguishing agent and flies to the surface, water source satisfied the requirements to fetch water, and the valve closing of this process extinguishing chemical capsule 11, extinguishing chemical does not discharge.
(4) fire extinguishing.Controlled the air capacity being filled with in extinguishing chemical capsule 11 by air bags valve, thus controlling the amount of the extinguishing chemical therefrom extruded so that it is just mix by the volume ratio of regulation with the pure water of full well-bucket, flight is opened well-bucket to overhead, the scene of a fire and is spilt mixed liquor fire extinguishing.
(5) judge to put out a fire to save life and property effect.If mountain fire does not put out, after carrying out (6) step, continue fire extinguishing；Otherwise, put out a fire to save life and property end.
(6) moisturizing.The extinguishing chemical of extinguishing chemical capsule 11 is available for repeatedly using, i.e. the valve closing of extinguishing chemical capsule 11 after mixing single barrel of fire extinguishing water preparation, and residue extinguishing chemical is for follow-up water intaking, and therefore helicopter directly flies to surface, the water source water intaking satisfied the requirements.
