Helicopter-mounted high-pressure water-saving fire-extinguishing water cannon used for fighting electric transmission line mountain fires

Abstract

The invention discloses a helicopter-mounted high-pressure water-saving fire-extinguishing water cannon used for fighting electric transmission line mountain fires. The helicopter-mounted high-pressure water-saving fire water cannon comprises a gas supply mechanism, a water supply mechanism, a high-pressure gas chamber, a cannon bore, a cannon barrel, an infrared imager and a control box, wherein the gas supply mechanism is installed in a belly of a helicopter; the gas supply mechanism is communicated with the high-pressure gas chamber positioned below the belly; the cannon bore, the cannon barrel and the infrared imager are all installed below the belly; the high-pressure gas chamber is communicated with the cannon bore and separated by a gas chamber electromagnetic valve; the cannon bore and the cannon barrel are communicated and are separated by a cannon bore electromagnetic valve; the cannon bore is connected with the water supply mechanism installed in the belly; the control box is respectively connected with the gas supply mechanism, the water supply mechanism, the infrared imager, the gas chamber electromagnetic valve and the cannon bore electromagnetic valve. By utilizing the helicopter-mounted high-pressure water-saving fire water cannon, the small curvature spiral cannon barrel is adopted, the atomization effect of fire extinguishing liquid is good, the fire extinguishing liquid is saved on the premise of ensuring the fire extinguishing effect, and the problem that the lack of a large-scale water source needed by water drawing of the helicopter in a field is effectively solved.

Description

technical field [0001] The invention relates to a fire-extinguishing water cannon, in particular to a helicopter-carried high-pressure water-saving fire-extinguishing water cannon for fighting mountain fires in power transmission lines. Background technique [0002] Transmission lines often pass through mountain forests, and wild wildfires have caused serious damage to the power system. In order to cope with the multi-point, wide-ranging and random transmission line mountain fires, Hunan Electric Power Company has developed a lot of mountain fire fighting equipment, such as single-person backpack high-pressure water mist fire extinguishers, long-distance high-lift mobile fire extinguishing platforms, electric high-pressure fire extinguishers, etc. , played a better fire extinguishing effect. However, due to the complex terrain and inconvenient transportation in mountainous areas, the existing fire extinguishing equipment is still difficult to meet the mobility requirements ...

AI Technical Summary

Problems solved by technology

However, most of the existing helicopter fire extinguishing equipment is designed for large-scale forest fires, with high power and large load. For small-area mountain fires, it has poor maneuverability and poor economy; and the areas with high incidence of mountain fires are mostly hilly areas, and there is a serious shortage of water sources. , the water pumping device of the large helicopter is useless

However, the fire extinguishing water cannon carried by the existing helicopter has the following characteristics: (1) the power is relatively large

Generally, the single injection water volume of a single barrel is more than 10L, and the water consumption is relatively large; (2) Using high-pressure gas storage cylinders as power, the gas cylinders need to be replaced after each use, which is cumbersome and costly to operate; (3) Using IFEX - The fire extinguishing water cannon with 3000 pulse technology can automatically and continuously spray during the fire extinguishing process. When fighting a large fire, it can simplify the operation and have a good fire extinguishing effect. Waste of fire extinguishing fluid; (4) Lack of flame positioning device, relying entirely on the experience of the driver, the accuracy of fire extinguishing is not high
