Description

Technical Field

[0001] This utility model relates to the field of fire sprinkler head technology, and to a multi-functional adjustable fire extinguishing sprinkler head device. Background Technology

[0002] Existing fire sprinkler head designs typically lack the capability to replace the sprinkler head, which limits their adaptability and effectiveness in different firefighting scenarios. Especially when dealing with specific fires requiring continuous cooling and extinguishing, such as battery fires, and fires in environments with limited fluid resources such as water and extinguishing agents, the performance of traditional sprinkler heads often fails to meet the demands.

[0003] In addition, most existing fire sprinkler heads have water inlet at one end and water outlet at the other end, and there are fixed structures such as heat response triggers at the outlet end. Part of the water flow sprayed from the nozzle will collide with the fixed structure, causing some water flow direction to change, thus causing the water flow to disperse and affecting the fire extinguishing effect. Utility Model Content

[0004] To address the technical problems in existing technologies, this utility model provides a multi-functional adjustable fire extinguishing nozzle device. On the one hand, it can select the appropriate type of atomizing head and thermal response trigger to atomize the fluid according to different environments, thereby improving the adaptability of the fire extinguishing nozzle device. At the same time, it can reduce the consumption of fluids such as water resources and fire extinguishing agents. On the other hand, it can avoid the dispersion of water flow, thereby improving the fire extinguishing effect.

[0005] The technical solution includes a three-way pipe, a thermal response trigger, and an atomizing head. The first connection port of the three-way pipe is connected to a fluid supply pipe. The thermal response trigger is threadedly connected to the second connection port of the three-way pipe. The atomizing head is threadedly connected to the third connection port of the three-way pipe. It also includes a sealing assembly, which is installed inside the three-way pipe. The sealing assembly, the first connection port, and the second connection port are coaxially arranged.

[0006] The sealing assembly includes a push rod and a sealing gasket. One end of the push rod is slidably and sealingly connected to the tee pipe through the sealing gasket, and the other end abuts against the thermal response trigger. The sealing gasket is located between the first connection port and the third connection port. When the thermal response trigger is triggered, the sealing gasket slides toward the second connection port under the action of fluid, and the first connection port and the third connection port are connected.

[0007] Furthermore, the sealing assembly also includes a limiting plate and a return spring. The limiting plate is fixedly installed on the end of the top rod away from the sealing gasket. A fixing plate is provided between the second connection port and the third connection port. The return spring is sleeved on the top rod, with one end of the return spring fixedly connected to the fixing plate and the other end abutting against the limiting plate. When the thermal response trigger is triggered, the sealing gasket slides toward the second connection port under the action of the fluid and the elastic force of the return spring, and the first connection port and the third connection port are connected.

[0008] Furthermore, one end of the atomizing head is provided with a flow hole that communicates with the inside of the three-way tube, and the other end is provided with a spray hole that communicates with the outside. The flow hole is connected to the spray hole through a swirl groove.

[0009] Furthermore, a knob is fitted onto the atomizing head, and the knob is located at one end near the nozzle.

[0010] Furthermore, a groove is provided on the end of the atomizing head, the spray hole is connected to the groove, a connecting piece is slidably installed in the groove, and the width of the connecting piece is greater than the diameter of the spray hole. Multiple small holes of different diameters are spaced apart along the length of the connecting piece. When the connecting piece is slid, the spray hole is connected to the small holes of different diameters.

[0011] Furthermore, the distance between two adjacent holes is not less than the diameter of the nozzle.

[0012] Furthermore, the groove is provided with multiple positioning marks at intervals, and the positioning marks correspond one-to-one with the small holes. When the end of the connecting piece coincides with the positioning marks, the spray hole and the small hole are arranged coaxially.

[0013] Furthermore, the connecting piece is provided with two strip-shaped holes, which are symmetrically arranged on both sides of the plurality of small holes. The groove is provided with two threaded holes, which are symmetrically arranged on both sides of the spray hole. When the small hole is connected to the spray hole, the screw passes through the strip-shaped hole and the threaded hole to connect. The connecting piece is fixed relative to the atomizing head and fits tightly.

[0014] Beneficial effects:

[0015] 1. In this utility model, the arrangement of a three-way pipe, an atomizing head, and a sealing assembly including a top rod and a sealing gasket allows for the selection of appropriate types of atomizing heads and thermal response triggers to atomize fluids such as water and extinguishing agents entering the three-way pipe, improving the adaptability of the fire extinguishing nozzle device. Simultaneously, it reduces the consumption of fluids such as water and extinguishing agents, making it particularly suitable for environments requiring continuous cooling and extinguishing, such as battery fires. Specifically, the atomized fine water mist has a large surface area, effectively filtering toxic gases in the air and improving safety. Furthermore, the fine water mist can quickly cool the combustion module, effectively preventing thermal runaway and reducing the risk of fire reignition. It also avoids water dispersion, thereby improving the extinguishing effect. The threaded connection between the thermal response trigger and the three-way pipe allows for easy replacement of the thermal response trigger; the threaded connection between the atomizing head and the three-way pipe also allows for easy replacement of the atomizing head to adapt to different fire characteristics.

[0016] 2. In this utility model, the setting of the limiting plate and the return spring can improve the sliding speed of the sealing gasket and the response speed of the fire extinguishing nozzle device. Specifically, when the thermal response trigger is triggered, the limiting plate loses its limit and the return spring returns to its original length. Under the additional action of the return spring force, the limiting plate will quickly slide out from the second connection port, and at the same time drive the top rod and the sealing gasket to slide, so that the sealing gasket slides to the bottom of the third connection port or between the third connection port and the second connection port.

[0017] 3. The knob in this utility model allows for easy screwing on and off of the atomizing head, facilitating the assembly and disassembly of the atomizing head and the three-way tube.

[0018] 4. In this utility model, the size of the nozzle can be adjusted without replacing the atomizing head by using a sliding groove, connecting piece, and multiple small holes of different diameters to meet different fire extinguishing and cooling needs, thus improving the flexibility and adaptability of the fire extinguishing nozzle device. By setting the distance between two adjacent small holes to be no less than the diameter of the nozzle, it can be ensured that only one small hole is connected to the nozzle at any time. By setting multiple positioning marks, the sliding position of the connecting piece can be easily and quickly positioned, improving installation efficiency. Combined with the coaxial setting of the nozzle and the small holes, the atomization effect can be improved.

[0019] 5. In this utility model, the two strip holes, two threaded holes and screws can be used to fix the position of the connecting piece, prevent the connecting piece from falling off the atomizing head, and at the same time make the connecting piece fit tightly with the atomizing head, further improving the atomization effect.

[0036] This utility model provides a multi-functional adjustable fire extinguishing nozzle device, such as... Figure 1 , Figure 3 and Figure 5 As shown, the device includes a three-way pipe 1, a thermal response trigger 2, and an atomizing head 3. The first connection port of the three-way pipe 1 is connected to a fluid supply pipe. The thermal response trigger 2 is threadedly connected to the second connection port of the three-way pipe 1. The atomizing head 3 is threadedly connected to the third connection port of the three-way pipe 1. One end of the atomizing head 3 is provided with a flow hole communicating with the inside of the three-way pipe 1, and the other end is provided with a spray hole 6 communicating with the outside. The flow hole is connected to the spray hole 6 through a swirling groove. The flow hole, the spray hole 6, and the third connection port are all coaxially arranged. Multiple swirling grooves can be provided. The fluid entering the flow hole from the inside of the three-way pipe 1 forms turbulence through the swirling groove and is then sprayed out through the spray hole 6 to achieve atomization of the fluid. The device also includes a sealing assembly 4, which is installed inside the three-way pipe 1. The sealing assembly 4, the first connection port, and the second connection port are coaxially arranged.

[0037] The sealing assembly 4 includes a push rod 41 and a sealing gasket 42. One end of the push rod 41 is slidably and sealingly connected to the tee pipe 1 through the sealing gasket 42, and the other end abuts against the thermal response trigger 2. The sealing gasket 42 is located between the first connection port and the third connection port. When the thermal response trigger 2 is triggered, the sealing gasket 42 slides toward the second connection port under the action of fluid, and the first connection port and the third connection port are connected.

[0038] In this embodiment, the arrangement of the three-way pipe 1, the atomizing head 3, and the sealing assembly 4 including the top rod 41 and the sealing gasket 42 allows for the selection of appropriate types of atomizing heads 3 and thermal response triggers 2 to atomize fluids such as water and extinguishing agents entering the three-way pipe 1 according to different environments. This improves the adaptability of the fire extinguishing nozzle device and reduces the consumption of fluids such as water and extinguishing agents. It is particularly suitable for environments requiring continuous cooling and extinguishing, such as battery fires. Specifically, the atomized fine water mist has a large surface area, which can more effectively filter toxic gases in the air and improve safety. In addition, the fine water mist can quickly cool the combustion module, effectively preventing thermal runaway and reducing the risk of fire reignition. It can also avoid water flow dispersion, thereby improving the extinguishing effect. The threaded connection between the thermal response trigger 2 and the three-way pipe 1 allows for easy replacement of the thermal response trigger 2. The threaded connection between the atomizing head 3 and the three-way pipe 1 also allows for easy replacement of the atomizing head 3 to adapt to different fire characteristics.

[0039] In this utility model, preferably, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the sealing assembly 4 also includes a limiting plate 43 and a return spring 44. The limiting plate 43 is fixedly installed on the end of the top rod 41 away from the sealing gasket 42. A fixing plate 5 is provided between the second connection port and the third connection port. The return spring 44 is sleeved on the top rod 41, and one end of the return spring 44 is fixedly connected to the fixing plate 5, while the other end abuts against the limiting plate 43. When the thermal response trigger 2 is triggered, the sealing gasket 42 slides toward the second connection port under the action of the fluid and the elastic force of the return spring 44, and the first connection port and the third connection port are connected.

[0040] In this embodiment, the sliding speed of the sealing gasket 42 and the response speed of the fire extinguishing nozzle can be improved by setting the limiting plate 43 and the return spring 44. Specifically, when the thermal response trigger 2 is triggered, the limiting plate 43 loses its limit and the return spring 44 returns to its original length. Under the additional action of the elastic force of the return spring 44, the limiting plate 43 will quickly slide out from the second connection port, and at the same time, it will drive the top rod 41 and the sealing gasket 42 to slide, so that the sealing gasket 42 slides to the bottom of the third connection port or between the third connection port and the second connection port.

[0041] In this utility model, preferably, such as Figure 1 , Figure 2 and Figure 6 As shown, a knob is fitted on the atomizing head 3, and the knob is located at one end near the nozzle 6.

[0042] In this embodiment, the knob allows for easy screwing of the atomizing head 3, facilitating the assembly and disassembly of the atomizing head 3 and the three-way tube 1.

[0043] In this utility model, preferably, such as Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the end of the atomizing head 3 is provided with a groove 31, and a connecting piece 7 is slidably installed in the groove 31. The width of the connecting piece 7 is greater than the diameter of the spray hole 6. To prevent the connecting piece 7 from detaching from the atomizing head 3, the groove 31 can be a T-shaped groove, and the connecting piece 7 can be a T-shaped connecting piece that matches the T-shaped groove. The connecting piece 7 has multiple small holes 8 of different diameters spaced apart along its length. The diameters of the small holes 8 are 0.8mm, 1.0mm, 1.2mm, 1.5mm, etc., and the largest small hole 8 is equal to the spray hole 6. In addition, to improve the atomization range and spray distance, the small holes 8 can be set at a certain angle, preferably 60° to 70°. When the connecting piece 7 is slid, the spray hole 6 communicates with the small holes 8 of different diameters. To facilitate the sliding of the connecting piece 7, handles 12 can be provided at both ends of the connecting piece 7. In addition, the length of the connecting piece 7 is less than the length of the groove 31 to ensure that the connecting piece 7 is always located in the groove 31 when sliding.

[0044] In this embodiment, by setting up the slide groove 31, the connecting piece 7 and multiple small holes 8 with different diameters, the size of the spray hole 6 can be adjusted without replacing the atomizing head 3, so as to meet different fire extinguishing and cooling needs and improve the flexibility and adaptability of the fire extinguishing nozzle device.

[0045] In this utility model, preferably, such as Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the distance between two adjacent small holes 8 is not less than the diameter of the spray hole 6; multiple positioning marks 9 are spaced apart in the groove 31, and the multiple positioning marks 9 are evenly distributed on both sides of the spray hole 6. Specifically, the positioning marks 9 are set at the bottom of the groove 31, and the positioning marks 9 on one side correspond one-to-one with the small holes 8. When the end of the connecting piece 7 coincides with the positioning mark 9, the spray hole 6 and the small holes 8 are set on the same axis.

[0046] In this embodiment, by setting the distance between two adjacent small holes 8 to be no less than the diameter of the spray hole 6, it can be ensured that only one small hole 8 is connected to the spray hole 6 at a time; by setting multiple positioning marks 9, the sliding position of the connecting piece 7 can be conveniently and quickly positioned, improving installation efficiency; and by setting the spray hole 6 and the small hole 8 to be coaxial, the atomization effect can be improved.

[0047] In this utility model, preferably, such as Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, the connecting piece 7 is provided with two strip holes 10, which are symmetrically arranged on both sides of the plurality of small holes 8. The sliding groove 31 is provided with two threaded holes 11, which are symmetrically arranged on both sides of the spray hole 6. When the small hole 8 is connected to the spray hole 6, the screw passes through the strip hole 10 and connects with the threaded hole 11. The connecting piece 7 is fixed relative to the atomizing head 3 and fits tightly.

[0048] In this embodiment, the two strip holes 10, the two threaded holes 11 and the screws can be used to fix the position of the connecting piece 7, prevent the connecting piece 7 from falling off the atomizing head 3, and at the same time make the connecting piece 7 fit tightly with the atomizing head 3, thereby further improving the atomization effect.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
