Described control cabinet 12 is arranged in ventral, and control cabinet 12 is connected with air compressor 1, water pump 2, air-compressor valve 4, water pump valve 5, air chamber magnetic valve 8, bore magnetic valve 9, infrared thermoviewer 11 respectively.
Operation principle of the present utility model is as follows:
(1) before fire extinguishing, getting extinguishing fluid case 3 capacity is 1000L, and gun tube 10 internal diameters are 20mm, and barrel (two gun tube) length is respectively 2m, 0.5m, 0.3m.The specified pressure of air compressor 1 is 3.5MPa, and plenum chamber 6 operating pressures are 3.0MPa, and bore 7 volumes are 7L;
(2) while fire extinguishing, use infrared thermoviewer 11 to analyze the range-azimuth of burning things which may cause a fire disaster, adjust helicopter position, make it apart from burning things which may cause a fire disaster 20m, start fire-extinguishing gun system, within the time of 3.5s, air compressor 1 completes to the interior inflation of plenum chamber 6, makes the interior pressure of plenum chamber 6 reach 3.0MPa; Meanwhile, water pump 2 completes and from extinguishing fluid case 3, extracts 7L extinguishing fluid to bore 7, and now firing button is activated; Aim at burning things which may cause a fire disaster and press firing button, air chamber magnetic valve 8, bore magnetic valve 9 are opened within the time that is no more than 18ms, and the gas in plenum chamber 6 mixes rapidly with the water bullet in bore 7, form gas-liquid mixture, complete primary atomization; A droplet spiral gun tube 10 of process small curve within the extremely short time, collides continuously with tube wall, completes secondary-atomizing; Secondary droplet is diffusion rapidly from gun muzzle ejection, completes three atomizations;
(3) expand more than 1700 times through the extinguishing fluid volume of three atomizations, spray to burning things which may cause a fire disaster with the initial velocity of 120m/s, range reaches 50m, and jet width reaches 6m; After three atomizations, 7L extinguishing fluid becomes the droplet of diameter 5 ~ 180 μ m, and droplet particle increases greatly with the surface area that contacts of fire, and the larger droplet of particle is along with high velocity air rushes at burning things which may cause a fire disaster, plays the effect of putting out, putting out by water; The gasification around burning things which may cause a fire disaster of the less droplet of particle, plays isolated air, takes away the effect of heat, and the fine and close salt deposit forming after the extinguishing chemical adding in extinguishing fluid evaporation covers comburant surface, can greatly improve the burning-point of comburant, stops resume combustion;
(4) after being once sent, control cabinet 12 automatic stay firing buttons, air chamber magnetic valve 8, bore magnetic valve 9 are closed automatically, air-compressor valve 4, water pump valve 5 are opened automatically, air compressor 1 and water pump 2 complete respectively above-mentioned inflation, water filling process again, wait for transmitting next time, wherein, the time that air compressor 1 and water pump 2 complete inflation, water filling process is no more than 3.5 seconds.
What the utility model used is the mode that two gun tubes combine side by side, and every transmitting once can spraying fire-extinguishing liquor 7 × 2=14L, and field trial shows, fully the 14L extinguishing fluid after atomization can be 3m, naked light area 3m to flame height
2disposable the putting out of flare.And 1000L extinguishing fluid can be launched for more than 70 times, can extinguish open flame area more than 200 square meters, more than sufficient to putting out a fire to save life and property of the small size mountain fire of tens of square meter naked lights near number square meters transmission line of electricity.Therefore use this extinguishing water cannon good extinguishing effect, mobility strong, and without the moisturizing that seeks sources of water midway, even rush to rapidly next fire point and put out a fire to save life and property having put out also can not shut down after a fire point, catered to the fire extinguishing demand of transmission line forest fire completely.
