Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-4As shown, the utility model provides a technical solution: a building fire sprinkler pipeline, including a mounting plate 1, a vertical cylinder 2, a water spray box 3, a water inlet pipe 4, a plurality of first water outlet holes 5, a plurality of second water outlet holes 6, a plurality of third water outlet holes 7 and a booster assembly, the mounting plate 1 is provided with a plurality of mounting holes 15 distributed in a circular array, the vertical cylinder 2 is fixedly mounted on the bottom of the mounting plate 1, the water spray box 3 is rotatably mounted on the bottom of the vertical cylinder 2, an annular guide groove 11 is provided at the bottom of the vertical cylinder 2, an annular guide rod 12 is slidably mounted in the annular guide groove 11, the top of the water spray box 3 is an open structure and is fixedly connected to the annular guide rod 12, the water inlet pipe 4 is fixedly mounted on the left side of the vertical cylinder 2, and the booster assembly is provided. Placed in the vertical cylinder 2, the booster assembly is used to increase the water pressure in the vertical cylinder 2. A plurality of first water outlet holes 5 distributed in a circular array are provided on the vertical cylinder 2, a plurality of second water outlet holes 6 distributed in a circular array are provided on the annular side wall of the water spray box 3, and a plurality of third water outlet holes 7 distributed in a circular array are provided at the bottom of the water spray box 3. The plurality of third water outlet holes 7 are all inclinedly arranged. Through the plurality of first water outlet holes 5, the enhanced water pressure can be utilized to spray water to a farther range and increase the coverage area. By controlling the water spray box 3 to rotate, the water flow passing through the plurality of second water outlet holes 6 and the third water outlet holes 7 forms a water cover to wrap and cover the flame, thereby improving the effect of extinguishing the initial fire.

[0025] In this embodiment, the above-mentioned booster assembly includes a rotating shaft 8, a plurality of baffles 9 and a spiral blade 10. The rotating shaft 8 is rotatably mounted on the top inner wall of the vertical cylinder 2. The plurality of baffles 9 are fixedly mounted on the top of the rotating shaft 8 and are evenly distributed. It should be noted that the water inlet pipe 4 is located at the left rear of the vertical cylinder 2. The water flow gushing out of the water inlet pipe 4 impacts the baffle 9, thereby pushing the baffle 9 and the rotating shaft 8 to rotate. The spiral blade 10 is fixedly mounted on the rotating shaft 8 and is located below the plurality of baffles 9. The spiral blade 10 is in sliding contact with the annular inner wall of the vertical cylinder 2. Through the above-mentioned arrangement, the water pressure in the vertical cylinder can be increased, and the water flow can be accelerated to spray out from the water outlet.

[0026] In this embodiment, a fan blade 14 is fixedly installed at the bottom end of the above-mentioned rotating shaft 8. The fan blade 14 includes four blades distributed in a circular array and are all made of high-quality stainless steel. The bottom end of the rotating shaft 8 extends to the bottom of the water spray box 3. The bottom of the water spray box 3 is fixedly connected to the rotating shaft 8. Two symmetrically distributed connecting holes 13 are opened at the bottom of the vertical cylinder 2.

[0027] Through the above structure, a building fire sprinkler pipe provided by the utility model can, when a fire occurs, use the water flow in the fire pipe to push the baffle plate 9, thereby driving the rotating shaft 8 and the spiral blade 10 to rotate, thereby increasing the water pressure in the vertical cylinder 2, accelerating the water flow to spray outward from multiple water outlets, expanding the coverage range, increasing the water output, forming a multi-layer water flow to cover the flame, and improving the effect of extinguishing the initial fire. The rotation of the rotating shaft 8 can also be used to drive the fan blades 14 to rotate, thereby breaking up the water flow sprayed from the bottom of the water spray box 3 and blowing it toward the flame, thereby improving the coverage and suppression effect of the flame. In specific use, when a fire occurs, high temperature triggers the alarm device and automatically controls the operation of the fire sprinkler system, and the fire pipe After the water flow in the channel enters the vertical cylinder 2, it impacts the baffle plate 9, thereby driving the rotating shaft 8 and the spiral blades 10 to rotate. As the spiral blades 10 rotate, the water pressure in the vertical cylinder 2 is gradually increased, prompting the water in the vertical cylinder 2 to accelerate through the multiple first water outlets 5 to spray outward, thereby expanding the coverage area. The rotating shaft 8 drives the water spray box 3 to rotate, and uses the water pressure to rotate and spray water outward from the multiple second water outlets 6 and the third water outlets 7, forming a multi-layer water flow or water mist to cover the flame, which greatly improves the effect of extinguishing the initial fire. At the same time, the rotating shaft 8 drives the fan blades 14 to rotate, and the rotating fan blades 14 break up the water sprayed from the bottom of the water spray box 3 and blow it toward the flame, thereby improving the coverage and suppression effect on the flame.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
