[0042] As shown in Figures 1 to 4 , Figure 6 and Figure 9 , the utility model also proposes a kind of live water cloud robot fire water cannon, including fire-fighting robot and live water cloud fire water cannon installed on the chassis of the fire-fighting robot, the fire water cannon includes water cannon body 300, the water cannon body 300 includes water inlet pipe, one end of the water inlet pipe is equipped with the nozzle as described in any one of the above embodiments, and the nozzle is detachably connected with the water inlet pipe.It can be understood that the water cannon body 300 and the nozzle are the same as or similar to the water cannon body 300 and the nozzle described in the above embodiments, to avoid repetition, which will not be repeated here.

[0045] It can be understood that the temperature active water in this application refers to the water with temperature reaching between 160°C to 260°C and pressure reaching between 2Mpa to 10Mpa, which is sprayed out through the nozzle 100 in the above embodiment, and after being sprayed out, forms a mixture of steam and water droplets, wherein the water that is not heated enough is converted into a metastable state in an instant (10 -4 —10 -9 seconds) and then forms a burst of boiling, with the composition of the not heated enough steam accounting for 30%, the metastable state water droplets of 0.01-10.0 microns accounting for 70%, most of the water droplets having a diameter of 0.1-5.0 microns, and after being sprayed out, being able to float in the air, having four best fire extinguishing effects of water cooling, nitrogen dilution, foam isolation and chemical inhibitor inhibition, being able to effectively weaken the dispersed heat flow, floating for a long time to fill the space, effectively protecting the enclosed space from heat radiation and performing three-dimensional fire extinguishing with maximum efficiency, preventing open fire from burning, precipitating to eliminate smoke and reduce temperature, without the need for rescue personnel to enter the room, and being able to complete the surface and three-dimensional extinguishing of natural, underground and engineering fires with a height or depth of 350 meters and a distance of 2 kilometers.

[0046] It can also be understood that due to the high temperature and pressure of the temperature active water, using a traditional water gun or water cannon can cause damage to the user, and also cannot achieve the above-mentioned formation of active water cloud floating in the air. Using the nozzle in the above embodiment, due to the unique design of the cross-sectional area between the water outlet hole and the water inlet channel, when the high-pressure water passes through the small hole of the nozzle, the flow rate increases and the pressure is released. At the same time, due to the extremely fast jet speed and the high pressure before jetting, in the instant of jetting, the high-pressure water flowing out of the small hole encounters air and can be cut into tiny water droplets to form an active cloud floating in the air. Therefore, the temperature of the water stream reaching 160°C to 260°C is greatly reduced after jetting, with a temperature as low as 42°C, so that the jet stream sprayed out is not harmful to the skin, improving safety. In addition, due to the design of the nozzle, the water pressure sprayed out is small and the flow rate is fast, thereby expanding the jet range. At the same time, since the water is cut into tiny water droplets to form an active cloud floating in the air, it can quickly spread and diffuse to fill the fire extinguishing space, and 1 liter of temperature active water jet stream can fill 5 cubic meters of space per second, which is 10 times more water-saving than traditional fire extinguishing.

[0047] In summary, the jet stream sprayed out through the nozzle described in the above embodiment has the advantages of not harming the skin, a temperature as low as 42°C, normal atmospheric pressure, rapid cooling, 100% smoke precipitation, high-efficiency fire extinguishing, safety and environmental protection, and fundamentally solves the loss and waste caused by using a large amount of water.
