Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figures 1 to 6This utility model provides a technical solution: a fire sprinkler device for building services, including a liquid delivery pipe 1, a connecting frame 2 and a booster nozzle 13. Both ends of the liquid delivery pipe 1 are fixed with connecting frames 2. The bottoms of the two connecting frames 2 are rotatably connected to the protruding shafts 4 at both ends of the rotating platform 3 through bearings. The upper end of the rotating platform 3 is fixed with a housing 5. A backup power supply 6 is provided inside the housing 5. A box body 7 is fixed on one side of the housing 5. A booster pump 8 is fixed inside the box body 7. The negative pressure end of the booster pump 8 is connected to the first solenoid valve 10 through a first telescopic pipe 9. The other end of the first solenoid valve 10 is connected to the liquid delivery pipe 1 through a pipe. The other end of the booster pump 8 is connected to the connecting pipe 11 through a pipe. The bottom of the connecting pipe 11 is connected to the booster nozzle 13 through a second telescopic pipe 12.

[0028] The lower end of the rotating platform 3 is provided with a slewing bearing 14. The rotating end of the slewing bearing 14 is fixedly sleeved with a first driven gear ring 16 that meshes with the first drive gear 15. The bottom of the rotating end of the slewing bearing 14 is fixed with an arc-shaped frame 17. A sliding member 18 is provided on the surface of the arc-shaped frame 17 along the guide groove in the middle of the arc-shaped frame 17. The bottom of the sliding member 18 is fixed to the pressurizing nozzle 13 by a U-shaped frame 19 and screws.

[0029] An L-shaped frame 21 is fixed to the front end of the rotating platform 3. A two-axis servo platform 22 is fixed to the bottom of the L-shaped frame 21. An infrared camera 23 is rotatably connected to the bottom of the two-axis servo platform 22. The infrared camera 23 is connected to a tracker 24 at the front end of the L-shaped frame 21 via a wire. The tracker 24 is connected to a remote controller 25 at the front end of the L-shaped frame 21 via a wire. Considering that fire sprinkler devices are used in fire sprinkler systems, when a fire occurs, fire water is evenly sprayed through the sprinkler heads to control the fire in a certain area. Most existing fire sprinkler devices achieve the function of controlling the fire by increasing... While large-area spraying enhances the spraying effect, it lacks the ability to track and extinguish fires based on their location. This utility model patent addresses this drawback by using an infrared camera 23, a two-wheeled servo platform, a tracker 24, and a remote control module to achieve the tracking function. The device's first small motor 28, second small motor 29, and third small motor 37 enable the pressurized nozzle 13 to track and extinguish fires at their location. This structure suppresses initial fires, and the extinguishing footage is transmitted to remote control personnel via the infrared camera 23 and the remote control module, allowing them to monitor the fire extinguishing status.

[0030] Among them, a second driven gear ring 27 that meshes with the second drive gear 26 is fixedly sleeved on the outside of the protruding shaft 4 on one side of the rotating platform 3. The second drive gear 26 is fixedly installed outside the output shaft of the first small motor 28, and the first small motor 28 is fixed to one side of the connecting frame 2 through the housing. By setting the first small motor 28 to drive the second drive gear 26, when the first small motor 28 is turned on, the drive shaft of the second drive motor drives the second drive gear 26 to rotate. At this time, the second driven gear ring 27 will drive the protruding shaft 4 of the rotating platform 3 to rotate, thereby adjusting the front and rear spray angle of the booster nozzle 13.

[0031] The bottom of the rotating platform 3 is fixed with a second small motor 29 through a box. The output shaft of the second small motor 29 is fixed with the first drive gear 15. The second small motor 29 drives the first drive gear 15. The rotation of the first drive gear 15 will cause the second driven gear ring 27 meshing with it to rotate. After the second driven gear rotates, the horizontal position of the booster nozzle 13 can be adjusted.

[0032] The rotating platform 3 has a three-way pipe 30 fixed at its front end. The upper end of the three-way pipe 30 is connected to the second solenoid valve 32 through the third telescopic pipe 31, and the other end of the second solenoid valve 32 is connected to the liquid delivery pipe 1. Both ends of the three-way pipe 30 are connected to the vertical pipe 33 at the bottom of the first platform through pipes. The bottom of the two vertical pipes 33 are connected to atomizing nozzles 34. The second solenoid valve 32 is used to open and close the water circuit of the two atomizing nozzles 34. After the second solenoid valve 32 is opened, the liquid enters the vertical pipe 33 and is sprayed in conjunction with the atomizing nozzles 34. The spray from the atomizing nozzles 34 forms a water mist barrier, thereby preventing the spread of fire.

[0033] The middle part of the sliding member 18 is rotatably connected to a guide shaft 36 that matches the arc groove 35 on the surface of the arc frame 17. A third small motor 37 is provided on the back of the sliding member 18, and the output shaft of the third small motor 37 passes through the middle part of the sliding member 18 and is fixed to the gear column 38. The outside of the gear column 38 is engaged with the snap teeth 20 on the surface of the arc frame 17. At the same time, the third small motor 37 drives the gear column 38. During the rotation of the gear column 38, the sliding member 18 will move along the arc frame 17, so that the pressurized nozzle 13 can complete the adjustment of another angle.
