Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

An automatic sprinkler fire extinguishing device, as shown in Figure 1 and Figure 2, includes several water pipes 2 fixed on the top of the wall 1 and sprinkler heads 3 connected to the water pipes 2. The water pipe 2 includes a horizontal pipe 21 and a vertical pipe 22 whose end is fixed to the sprinkler head 3. The wall top 1 is equipped with a fixing assembly 10 connected and fixed to the horizontal pipe 21; the wall top 1 is fixed by the fixing assembly 10 and the horizontal pipe 21, Furthermore, the position of the water pipe 2 is fixed, and the fixing assembly 10 can be conveniently and stably fixed to the horizontal pipe 21 .

The fixing assembly 10 includes a support rod 101 installed and fixed on the lower surface of the wall top 1, and a clamping hoop 102 welded to the bottom end of the support rod 101 and sleeved on the outer wall of the horizontal pipe 21; The upper hoop 1021 and the lower hoop 1022 matched with the upper hoop 1021, the two ends of the upper hoop 1021 and the lower hoop 1022 are installed with bolts 11 that run through the upper hoop 1021 and the lower hoop 1022, and the bolts 11 are threaded A nut 12 is attached.

The upper hoop 1021 and the lower hoop 1022 clamp the horizontal pipe 21 through the connection and cooperation of the bolt 11 and the nut 12, and the clamping hoop 102 is fixed below the top of the wall 1 through the support rod 101, so that the water pipe 2 is stably fixed on the top of the wall 1 Below, the water pipe 2 is not easy to fall off from the top of the wall 1 . When the water pipe 2 needs to be replaced or in other situations, the nut 12 is rotated to disengage the nut 12 from the bolt 11 , so that the lower hoop 1022 is separated from the upper hoop 1021 , and the water pipe 2 is conveniently disassembled.

As shown in Figures 3 and 4, the sprinkler head 3 includes a threaded pipe 31 threadedly connected to the vertical pipe 22, a yoke arm seat 32 integrally formed at the end of the threaded pipe 31, and yoke arms integrally formed at both ends of the yoke arm seat 32. Frame 33, and, the other end of yoke arm frame 33 is fixedly installed splash plate 34. The yoke arm seat 32 is provided with a water spray hole 4, and the water spray hole 4 is embedded with a sealing seat 5 for closing the water spray hole 4; the middle of the splash plate 34 is provided with a screw hole 7, and the screw hole 7 is internally threaded with a screw 8. There is a glass body 6 in contact between the screw 8 and the sealing seat 5, and the inside of the glass body 6 is closed and filled with a sensitive liquid whose volume changes significantly with temperature changes.

The threaded pipe 31 is threadedly connected with the vertical pipe 22, so that the sprinkler head 3 is easy to install and disassemble, and the sprinkler head 3 and the vertical pipe 22 are fixed firmly. When a fire breaks out, when the temperature rises to a certain value, the sensitive liquid expands to make the glass body 6 explode, so that the sealing seat 5 falls off from the yoke arm seat 32 under the water pressure and its own gravity, so that the water flows from the water spray hole 4 along the water pipe 2 Spray, and fall through splash plate 34 and carry out fire extinguishing. Thereby realized automatic sprinkler fire extinguishing when breaking out of fire, has stopped fire spreading effectively in time. The friction between the screw 8 and the vitreous body 6 makes the vitreous body 6 more tightly conflicted between the screw 8 and the sealing seat 5, making the glass body 6 more difficult to fall off and greatly increasing the stability of the vitreous body 6 being fixed.

The splash plate 34 has a curved surface, and after the water is sprayed onto the splash plate 34, it is guided by the splash plate 34 and sprayed out in an umbrella shape, so that the water can be sprinkled in a larger area, and the impact of the water flow on the inner wall of the splash plate 34 is reduced. And downward straight-line rebound sprays, and causes the too small situation of the scope of water spray, has increased the effect of sprinkler fire extinguishing. The outer circumference of the splash plate 34 is integrally formed with evenly distributed tooth flutes 9 along the circumferential direction, and water is sprayed from the gaps of the tooth flutes 9, and the impact force of the water is then increased, so that the water is sprayed more openly, and the spraying effect is further increased. scope.

Sprinklers 3 are evenly distributed, and each sprinkler 3 is surrounded by six sprinklers 3 forming a regular hexagon; the diameter of the sprinkler 3 spray range is greater than the distance between two adjacent sprinklers 3, and every three The water spraying ranges of two adjacent sprinkler heads 3 all have a common intersection point, so that the water spraying ranges of adjacent sprinkler heads 3 have a small overlap, and the sprinkler heads 3 can spray to every corner of the space. In the event of a fire, the sprinkler head 3 can spray water without any dead angle, and the limited space can be fully and effectively used to minimize the overlapping range of the sprinkler head 3 spraying water, and the least amount of water can be used to achieve the effect of saving water resources.

The overall working process: when a fire occurs, when the temperature reaches a certain value, the sensitive liquid expands to cause the glass body 6 to explode, and water is sprayed out from the sprinkler 3 through the water pipe 2 to extinguish the fire; each sprinkler 3 is surrounded by six regular hexagonal Sprinklers 3 are surrounded, and the diameter of the spraying area of sprinklers 3 is greater than the distance between two adjacent sprinklers 3, making full use of the limited space for sprinkler fire, saving water resources.

The above-mentioned embodiment is only an explanation of the utility model, and it is not a limitation of the utility model. Those skilled in the art can make modifications to the embodiment without creative contribution as required after reading this specification, but as long as the utility model All claims are protected by patent law.
