[0024] Example

[0025] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0026] A building fire protection Internet of Things system alarm device comprises a base 1, a lifting assembly 2 is arranged on the top of the base 1, the lifting assembly 2 comprises a self-locking motor 201, the self-locking motor 201 is fixed to the top of the base 1, a screw rod 202 is fixedly connected to the output end of the self-locking motor 201, a lifting column 203 is threadedly connected to the outer wall of the screw rod 202, a protrusion 204 is fixedly connected to the bottom of the first end of the lifting column 203, a slide plate 205 is arranged on the first end of the lifting column 203, the bottom of the slide plate 205 is fixed to the base 1, a limit block 206 is fixedly connected to the top of the second end of the slide plate 205, the second end of the limit block 206 is slidably connected to the first end of the lifting column 203, a mounting frame 3 is fixedly connected to the top of the lifting column 203, a nozzle 4 is penetrated and rotatably connected at both ends of the first side of the mounting frame 3, a pump 5 is fixedly connected to the second end of the nozzle 4, a water inlet hose 6 is fixedly connected to the second end of the pump 5, a smoke sensor 7 is fixedly connected to the second end of the top of the mounting frame 3, and an alarm 8 is fixedly connected to the first end of the top of the mounting frame 3.

[0027] In this embodiment, the self-locking motor 201 is started to drive the screw rod 202 to rotate, and the screw rod 202 drives the lifting column 203 to slide and lift along the limit block 206. At the same time, the protrusion 204 and the limit block 206 complete the limitation of the lifting height, thereby completing the adjustment of the height of the spraying fire extinguishing, thereby improving the spraying fire extinguishing range of the device.

[0028] A swing assembly 9 is provided at the first end of the nozzle 4, and the swing assembly 9 includes a swing fork 901. The swing fork 901 and the nozzle 4 are fixed to each other. A cam 902 is provided inside the swing fork 901. The second end of the cam 902 is rotatably connected to the mounting frame 3. The first end of the cam 902 is fixedly connected to a rotating shaft 903. The first end of the rotating shaft 903 is fixedly connected to a gear 904. The second side of the gear 904 is meshed with a rack 905. The bottom of the rack 905 is fixed to the base 1.

[0029] In this embodiment, while the gear 904 is driven to rise and fall by the mounting frame 3, the gear 904 is rotated with the help of the rack 905. At the same time, the gear 904 drives the rotating shaft 903 and the cam 902 to rotate. When the cam 902 rotates, it will push the swing fork 901 to swing in stages.

[0030] It should be noted that the utility model is a building fire protection Internet of Things system alarm device. When in use, the smoke sensor 7 and the alarm 8 are first connected to the network to complete the monitoring of the fire, and then the water inlet hose 6 is connected to the external water source. When the smoke sensor 7 and the alarm 8 detect a fire, the information is uploaded through the network, and the pump 5 and the self-locking motor 201 are started at the same time. The self-locking motor 201 drives the screw rod 202 to rotate, and the screw rod 202 drives the lifting column 203 to slide and lift along the limit block 206. At the same time, the protrusion 204 and the limit block 206 complete the limitation of the lifting height, thereby completing the adjustment of the height of the spraying and extinguishing, and improving the range of the spraying and extinguishing of the device. Synchronously, when the mounting frame 3 drives the gear 904 to rise and fall, the gear 904 rotates with the help of the rack 905. At the same time, the gear 904 drives the rotating shaft 903 and the cam 902 to rotate. When the cam 902 rotates, it will periodically push the swing fork 901 to swing, and the swing fork 901 drives the nozzle 4 to swing synchronously, thereby improving the range of the spraying and extinguishing of the device.
