The present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1 and fig. 2, the embodiment provides an automatic lifting wind-resistant high-pressure water mist fire extinguishing apparatus, which comprises a lifting mechanism 1 and a fire extinguishing nozzle 2.
The lifting mechanism 1 comprises a main water pipe 11, a branch water pipe 12, a T-shaped three-way pipe 13, a spring 14 and a water storage tank 15. The main water pipe 11 is connected with two transverse ends of the T-shaped three-way pipe 13 in an existing rotary sealing mode, so that the T-shaped three-way pipe 13 can rotate along the axial direction of the main water pipe 11. One end of the left side of the branch water pipe 12 is hermetically connected with one end of the T-shaped three-way pipe 13 in the longitudinal direction, and one end of the right side of the branch water pipe 12 is connected with the fire extinguishing nozzle 2. The water storage tank 15 is arranged at one end of the branch pipe 12 close to the fire extinguishing nozzle 2. The main water pipe 11 is disposed under the ceiling of a semi-open space (e.g., a shop with only a ceiling and no walls around the ceiling), and the branch water pipe 12 is connected to the ceiling by a spring 14, so that the main water pipe 11 and the branch water pipe 12 can be located at the same level. When a fire breaks out, pressure water enters the main water pipe 11 and flows into the water storage tank 15 through the branch water pipe 12, and with the increase of the water amount in the water storage tank 15, the spring 14 is stretched under the action of the gravity of the water, so that the T-shaped three-way pipe 13 rotates to drive the branch water pipe 12 to swing downwards until the branch water pipe is in a vertical state, and then fire extinguishment is carried out. Can let the shower nozzle 2 of putting out a fire after 12 downswings of a water pipe more be close to the burning things which may cause a fire disaster to storage water tank 15 can play the effect of interim retaining and pressure boost, promotes the fire extinguishing efficiency and the performance of shower nozzle 2 of putting out a fire. After the fire extinguishing is finished, as the water amount in the water storage tank 15 is reduced, the gravity of the water is not enough to enable the spring 14 to be in the stretching state, and the branch water pipe 12 is restored to the horizontal state again.
As shown in fig. 3 and 4, the fire sprinkler 2 includes a swirl pressurizing module 21 and a nozzle module 22. Wherein the cyclone pressurizing module 21 includes a tangential groove unit 211 and a direct incidence trapping unit 212.

A direct interception hole 212c, which penetrates the cap portion 212a and the insert portion 212b, is formed in the direct interception unit 212 to open into the circular hole of the tangential groove unit 211. Meanwhile, the tangential groove unit 211 and the direct projection interception unit 212 each have a diameter smaller than that of the branched water pipe 12.
When the water flow of the branch water pipe 12 enters the fire-extinguishing sprinkler 2, a part of water flow flows into the circular ring hole from the tangential groove 211a of the tangential groove unit 211 to form rotational flow water, the other part of water flow directly enters the circular ring hole through the direct projection interception hole 212c of the direct projection interception unit 212 to form direct flow water, the rotational flow water and the direct flow water meet in the circular ring hole to form strong turbulent flow motion, the pressure is increased for the nozzle module 22, the pressure of water flow jet is improved, the water flow jetted by the nozzle module 22 has larger jet distance, and a larger atomization cone angle can be formed.
As shown in fig. 3 and 5-7, the nozzle module 22 includes a direct jet nozzle 222, a swirler 223, and a water mist jet nozzle 224. A conventional water mist jet nozzle 224 is provided at the bottom end of the nozzle block 22 for ensuring a basic jetting effect. The direct spray nozzles 222 and the swirl nozzles 223 are evenly distributed around the water mist jet nozzle 224. Specifically, the three swirl nozzles 223 and the three direct injection nozzles 222 form regular hexagons which are alternately distributed around the fine water mist jet nozzle 224, the spray included angles formed by the water outlets of the swirl nozzles 223 or the direct injection nozzles 222 and the water outlet of the fine water mist jet nozzle 224 are 35-48 degrees, and 45 degrees is adopted in the embodiment.
