According to the invention, a plurality of groups of swing units 41 are arranged between the first movable frame 13 and the second movable frame 14, in the process of high-altitude operation, the first movable frame 13 and the second movable frame 14 are in a completely unfolded state, the first annular rod 411 and the second annular rod 412 are also completely stretched, high-altitude airflow can blow the first movable frame 13 and the second movable frame 14 to shake, the second movable frame 14 and the first movable frame 13 can shift to one side in the shaking process, the internal spaces of the first annular rod 411 and the second annular rod 412 on the shifted side are compressed, and the airflow is conveyed into the annular cavity 421 through the one-way output valve. In the process of shaking the first movable frame 13 and the second movable frame 14, the air flow in the first annular rod 411 and the second annular rod 412 has a buffering effect on the shaking, so that the shaking amplitude and the shaking frequency are reduced. On the other hand, the shaking capability is converted into the kinetic energy of the gas to be continuously input into the stabilizing ring 42 and ejected out of the jet hole 422 in a ring shape, the output of the water flow is pushed by the ring-shaped air flow, and the air flow restriction is formed outside the water flow, so that the early atomization consumption of the ejected water flow is avoided.
The working principle of the invention is as follows: when the fire fighting truck 11 runs to a fixed position, the rotating disc 12 rotates, the hydraulic telescopic rod 15 drives the first movable frame 13 to rise, and the driving unit 16 extends each second movable frame 14 to extinguish fire. The fixed pipe 21 and the movable pipe 22 are in a contracted state in a conventional state, when fire is needed to be extinguished, the movable pipe 22 extends out along with the second movable frame 14, and the sliding ring 24 and the fixed ring 26 support two ends of the movable pipe 22 respectively, so that the movable pipe 22 can still keep the stability of the structure in the extending state. The diversion pipe 232 inputs part of the water flow in the main pipe into the booster pump 231, and after being boosted, the water flow is returned to the main pipe through the return pipe 233. When the high-pressure water gun 311 works, water flows through the flow guide pipe 314 at a very high pressure, the pressure of the water flows acts on the pipe wall of the flow guide pipe 314, the extrusion spring 3124 is extruded, the extrusion spring 3124 extrudes the rubber ferrule 3123, the rubber ferrule 3123 expands to extrude the first connection ring 3121, the rotational friction between the first connection ring 3121 and the second connection ring 3122 is increased, and when the water flow speed is reduced, the rotational friction between the first connection ring 3121 and the second connection ring 3122 is reduced. The air current of high latitude can blow first adjustable shelf 13, second adjustable shelf 14 and rock, and second adjustable shelf 14 and first adjustable shelf 13 can be to one side skew at the in-process of rocking, and the first annular pole 411 of one side that is squinted, second annular pole 412 inner space are compressed, and the air current is carried the annular chamber 421 through one-way output valve in, and the air current is final from the efflux hole blowout.
