detailed description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In explaining the embodiments of the present invention, if a detailed description of related well-known elements or functions interferes with the gist of the present invention, the detailed description will be omitted.

Fig. 1 is a schematic diagram of the external structure of the movable multi-phase fire sprinkler head provided by the present invention.

Fig. 2 is a schematic diagram of the internal structure of the movable multi-phase fire sprinkler head provided by the present invention.

Referring to Fig. 1 and Fig. 2, the present invention provides a movable multi-phase fire sprinkler, comprising a sprinkler body 10, the sprinkler body 10 is provided with a liquid spray system 20, including a liquid pipe 21 arranged inside the sprinkler body 10, the liquid pipe 21 A liquid inlet 22 formed outside the spray head body 10 and a liquid spray port 23 provided at the lower end of the spray head body 10 , and a moving device 30 is also provided at the upper end of the spray head body 10 .

The moving device 30 includes: a slider 31 disposed inside the moving device 30 ; a sliding bar 32 connected to the slider 31 inside the moving device 30 and extending to the outside of the moving device 30 . The slider 31 can slide along the slide rod 32 to control the movement of the spray head, wherein the slider 31 can be a roller.

The movable multi-phase fire sprinkler head provided by the present invention can also be provided with a gas sprinkler system 40, including a gas pipe 41 arranged inside the shower head body 10, a gas inlet 42 formed outside the shower head body 10, and a gas inlet 42 arranged at the lower end of the shower head body 10. The gas nozzle 43 can be arranged in the middle part of the lower end of the liquid spray port 23 and is connected with the gas pipe 41 .

The gas pipe 41 can be arranged axially (that is, vertically) inside the liquid pipe 21 , or outside the liquid pipe 21 vertically parallel to it, and the user can choose according to needs.

The movable multi-phase fire sprinkler provided by the present invention can also include a mixing chamber 50, which is arranged inside the sprinkler body 10, and can fully mix the water coming in from the liquid inlet 22 with the auxiliary fire extinguishing additive. One end is connected with the liquid inlet 22, and the other end is connected with the liquid inlet 22. The liquid pipe 21 is connected to each other, and a pressurizing pump 60 may also be arranged in the mixing chamber 50 to pressurize the mixed liquid. After the spray head is equipped with a pressurizing pump 60, the requirements for the water supply pipeline are relatively low, and the fire extinguishing effect of the pressurized liquid is better.

In the movable multi-phase fire sprinkler provided by the present invention, the liquid inlet 22 and the gas inlet 42 can also be connected with telescopic tubes 70, which can improve the flexibility of the sprinkler when moving. The telescopic tube 70 can be a flexible tube, which is stretched and contracted in cooperation with the movable device 30 .

Hereinafter, the usage method of the movable fire sprinkler head provided by the present invention will be described.

In the movable multi-phase fire sprinkler provided by the present invention, when a fire does not occur, the telescopic tube 70 is in a contracted state, and the movable fire sprinkler is in a standby state. When a fire occurs, the slider 31 moves along the slide rod 32, thereby moving the nozzle to the sky near the fire source, and the telescopic tube 70 is in a stretched state, and delivers liquid and gas to the nozzle. The water entering through the liquid inlet 22 and the auxiliary fire extinguishing additive are fully mixed in the mixing chamber 50, and after being pressurized by the booster pump 60, they are sprayed out from the liquid spray port 23 through the liquid pipe 21 to extinguish the fire. At the same time, the gas spray system 40 Gases such as carbon dioxide, inert gas, and heptafluoropropane can also be sprayed to increase the fire extinguishing effect. The gas enters through the gas inlet 42, and is ejected from the gas nozzle 43 through the gas pipe 41, and simultaneously extinguishes the fire with the liquid ejected from the liquid spray port 23. If the fire is small, only liquid fire can be extinguished, and the user can choose the fire extinguishing method according to the actual fire situation.

The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the foregoing embodiments, but can be realized in various forms. The embodiments disclosed in this specification are provided only to make the disclosure of the present invention complete so that those skilled in the art can fully understand the scope of the present invention. The scope of protection of the present invention should be determined by the content of the claims.
