[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0038] Reference Figure 2 , Figure 3 and Figure 4 , an embodiment provided by the utility model: a smart fire sprinkler device, comprising a support plate 1, a hollow tube 3 is arranged on the bottom side of the support plate 1, a micro motor 4 is fixedly connected to the right side of the hollow tube 3, the output end of the micro motor 4 passes through the hollow tube 3 and is fixedly connected to a driving bevel gear 5, a cross fixing plate 6 is fixedly connected to the middle and lower part of the inner side of the micro motor 4, a rotating rod 7 is rotatably connected to the top of the cross fixing plate 6, a driven bevel gear 8 is fixedly connected to the middle and upper part of the outer side of the rotating rod 7, the driven bevel gear 8 is meshed and connected with the driving bevel gear 5, and a fan-shaped plate 9 is fixedly connected to the outer bottom of the driven bevel gear 8. A nozzle 10 is connected to the bottom end of the micro motor 4, an infrared flame detection locator 15 is fixedly connected to the left side of the bottom of the support plate 1, an adjusting mechanism 2 is arranged on the rear side of the bottom of the support plate 1, a sealing ring 14 is fixedly connected to the top of the outer side of the hollow tube 3, and the gap sizes on the cross fixing plate 6 match the corresponding fan-shaped plate 9 sizes respectively;

[0039] Specifically, when the infrared flame detection locator 15 detects a fire source, it will quickly locate the fire source and feed back this important information to the controller 205 in the form of an electrical signal. After receiving this signal, the controller 205 will immediately start the emergency response program, on the one hand, send out an alarm to notify personnel to evacuate, and on the other hand, start the intelligent water volume regulation system by controlling the micro motor 4. After receiving the command of the controller 205, the micro motor 4 will quickly start and drive the active bevel gear 5 to rotate. At the same time, the driven bevel gear 8 meshing with the active bevel gear 5 will also rotate, thereby driving the rotating rod 7 to rotate. The rotation of the rotating rod 7 will further affect the angle change between the fan plate 9 and the cross fixing plate 6. This angle change is the core mechanism of the intelligent water volume regulation system. When the angle between the fan plate 9 and the cross fixing plate 6 changes, the size of the water outlet will also be adjusted accordingly, thereby achieving precise control of the water output. In this way, the water output can be adjusted according to actual needs, which not only avoids the waste caused by excessive one-time water output, but also meets the different needs of users.

[0040] Reference Figure 1 The adjusting mechanism 2 includes a fixed frame 201, which is fixedly connected to the bottom rear side of the supporting plate 1, a servo motor 202 is fixedly connected to the right side of the interior of the fixed frame 201, a worm 203 is fixedly connected to the output end of the servo motor 202, a worm wheel 204 is fixedly connected to the middle and upper part of the outer side of the hollow tube 3, the worm wheel 204 is meshedly connected to the worm 203, and the left end of the worm 203 is rotatably connected to the left side of the interior of the fixed frame 201;

[0041] Specifically, the servo motor 202 can drive the worm 203 to rotate. The clever design of the worm 203 lies in its meshing relationship with the worm wheel 204. This meshing relationship allows the worm wheel 204 to rotate at the same speed and direction under the drive of the worm 203. The fixed connection between the worm wheel 204 and the hollow tube 3 allows the hollow tube 3 to rotate with the rotation of the worm wheel 204. In this process, the nozzle 10 is installed at the end of the hollow tube 3, so when the hollow tube 3 rotates, the nozzle 10 will also rotate. This design allows the nozzle 10 to flexibly adjust the spraying direction, thereby accurately locating the fire source. In this way, it can be ensured that the water source can be directly sprayed onto the fire source, thereby improving the fire extinguishing efficiency.

[0042] Reference Figure 1 and Figure 2 A booster pump 11 is fixedly connected to the top of the support plate 1, and the output end of the booster pump 11 is connected to a liquid outlet pipe 12, the bottom end of the liquid outlet pipe 12 passes through the support plate 1, the top end of the hollow tube 3 is internally rotatably connected to the bottom end of the liquid outlet pipe 12, and the input end of the booster pump 11 is connected to a liquid inlet pipe 13;

[0043] Specifically, the water pressure can be adjusted by the booster pump 11 so that the water sprayed by the nozzle 10 can spray the fire source more accurately.

[0044] Reference Figure 1 The regulating mechanism 2 further includes a controller 205, which is fixedly connected to the right side of the fixed frame 201. The fixed frame 201 is electrically connected to the servo motor 202, the booster pump 11, the micro motor 4 and the infrared flame detection locator 15 respectively. A protective cover 206 is provided on the outer side of the controller 205, and one end of the protective cover 206 is rotatably connected to the right side of the fixed frame 201;

[0045] Specifically, the controller 205 can control the operation of the servo motor 202, the booster pump 11, the micro motor 4 and the infrared flame detection locator 15, and the protective cover 206 can protect the controller 205 from being damaged by external factors.

[0046] Working principle: When encountering a fire, the infrared flame detection locator 15 detects the fire source and locates the fire source, and then feeds back the signal to the controller 205 to control the micro motor 4, the booster pump 11 and the servo motor 202. At this time, the booster pump 11 can adjust the water pressure and transport the external water source to the hollow tube 3 through the liquid outlet pipe 12. The water source will then be sprayed to the fire source through the nozzle 10, and the micro motor 4 can drive the active bevel gear 5 to rotate, and the driven bevel gear 8 will also rotate with it due to the engagement with the active bevel gear 5, thereby driving the rotating rod 7 to rotate. At this time, the water output can be adjusted according to the angle change between the fan plate 9 and the cross fixing plate 6, so as not to cause excessive one-time water output and cause waste, thereby meeting the needs of users, and the servo motor 202 can drive the worm 203 to rotate, and the worm wheel 204 will also rotate with it due to the engagement with the worm 203, thereby driving the hollow tube 3 to rotate, and the nozzle 10 will rotate with it, and the fire source can be located, thereby improving the fire extinguishing effect, thereby improving the practicality of the device.
