Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically to an adjustable fire sprinkler head. Background Technology

[0002] In the field of fire protection, fire sprinklers are a crucial component of fire protection systems. Their main function is to spray extinguishing agents in a timely manner when a fire occurs, control the spread of fire, and protect the lives and property of people.

[0003] Most fire sprinklers are fixed in design, and their spray position cannot be adjusted after installation. However, in actual building environments, the fire risk level, spatial layout, and potential fire source locations vary from area to area. For example, in some large warehouses, the location and method of goods stacking may change over time and with business needs, which means that fire sprinklers originally installed in fixed positions may not be able to effectively spray coverage to new fire risk areas. Therefore, an adjustable fire sprinkler is proposed to solve the above problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 3 An adjustable fire sprinkler head in this embodiment includes a sprinkler head body 1, and an adjustment component for adjusting the spray position is provided at the bottom of the sprinkler head body 1.

[0018] Please see Figure 1In this embodiment, the adjustment component includes a connecting hose 2 fixedly connected to the bottom of the nozzle body 1, a connecting block 3 fixedly connected to the other end of the connecting hose 2, a water spray plate 4 fixedly connected to the bottom of the connecting block 3, a threaded block 5 fixedly connected to the back of the connecting block 3, a threaded shaft 6 threadedly connected to the inner side of the threaded groove of the threaded block 5, and a motor 7 fixedly connected to the right end of the threaded shaft 6.

[0019] Specifically, a limiting frame 8 is fixedly connected to the left side of the motor 7, and a threaded block 5 is slidably connected between the inner top and bottom walls of the limiting frame 8. The height and width of the threaded block 5 are equal to the height and width inside the limiting frame 8, respectively.

[0020] It should be noted that the height and width of the threaded block 5 are equal to the height and width inside the limiting frame 8, respectively. This design ensures that the threaded block 5 will not wobble or have gaps when it moves inside the limiting frame 8, further enhancing the stability and accuracy of the adjustment component and ensuring the reliability of the spray position adjustment.

[0021] Specifically, the left end of the threaded shaft 6 is rotatably connected to the inner left side wall of the limiting frame 8, and the right end of the threaded shaft 6 passes through the threaded groove of the threaded block 5 and the inner right side wall of the limiting frame 8 in sequence and is fixedly connected to the output shaft of the motor 7.

[0022] Specifically, a motor cover 9 is fixedly connected to the right side of the limiting frame 8, and a heat dissipation vent is provided on the front of the motor cover 9.

[0023] It should be noted that the motor cover 9 can protect the motor 7 and prevent it from being damaged by the external environment.

[0024] Specifically, ceiling connecting shafts 10 are fixedly connected to the four corners of the top of the limiting frame 8.

[0025] It should be noted that the ceiling connecting shaft 10 is used to fix the entire adjustable fire sprinkler head to the ceiling, ensuring the stability and safety of the sprinkler head during use.

[0026] Specifically, a water-gathering cavity 301 is provided on the inner side of the connecting block 3, an inlet connected to the water-gathering cavity 301 is provided on the top of the inner side of the connecting block 3, and a water outlet 302 connected to the water-gathering cavity 301 is provided on the bottom of the inner side of the connecting block 3. The cross-sectional area of ​​the water-gathering cavity 301 is larger than the cross-sectional area of ​​the water outlet 302, and the position of the water outlet 302 corresponds vertically to that of the sprinkler plate 4.

[0027] It should be noted that the cross-sectional area of ​​the water collection chamber 301 is larger than that of the water outlet 302. This design allows the water flow to be buffered and concentrated after entering the water collection chamber 301, and then flows out from the water outlet 302 in a relatively stable flow, and finally sprays onto the water spray plate 4.

[0028] The working principle of the above embodiments is as follows: When the spray position needs to be adjusted, start motor 7. The output shaft of motor 7 starts to rotate. Since the output shaft of motor 7 is fixedly connected to the right end of threaded shaft 6, threaded shaft 6 will rotate together with the output shaft of motor 7. When threaded shaft 6 rotates in limit frame 8, it cooperates with the thread groove of threaded block 5. Since threaded block 5 is slidably connected between the inner top and bottom walls of limit frame 8, and its height and width are equal to the height and width inside limit frame 8, threaded block 5 can only move linearly along the axis of threaded shaft 6. When threaded shaft 6 rotates, threaded block 5 will move left and right along threaded shaft 6, thereby driving connecting block 3 and water spray plate 4 to move together, thus changing the position of water spray plate 4. While adjusting the position of the sprinkler disc 4, water flows out from the nozzle body 1, passes through the connecting hose 2 and enters the inlet of the connecting block 3, and then flows into the water collection chamber 301. Since the cross-sectional area of ​​the water collection chamber 301 is larger than the cross-sectional area of ​​the water outlet 302, the water flow is buffered and concentrated in the water collection chamber 301, and then flows out from the water outlet 302 with a relatively stable water flow, and finally sprays onto the sprinkler disc 4 to achieve the spraying function.

[0029] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
