In addition, some aspects disclosed in the utility model can be used alone, or used in any appropriate combination with other aspects disclosed in the utility model.

[0022] like Figure 1-4 As shown, the utility model provides an automatically activated fire sprinkler device, including a water tank 1, a protection box 2 is fixedly connected to the left side of the water tank 1, a spray mechanism 3 is arranged at the rear end of the inner cavity of the protection box 2, a transmission mechanism 5 is arranged at the front end of the inner cavity of the protection box 2, the spray mechanism 3 includes a water pump 31, the water inlet end of the water pump 31 is connected to the water tank 1, the water outlet end of the water pump 31 is connected to a hose 32, the other end of the hose 32 is connected to a connecting pipe 33, the end of the connecting pipe 33 away from the hose 32 is connected to a sprinkler head 34, a detection mechanism 4 is arranged on the left side of the front of the water tank 1, the detection mechanism 4 includes a connecting tube 41, and the back of the connecting tube 41 is fixedly connected to the water tank 1, the front of the connecting tube 41 is fixedly connected to a PLC controller 42, the back of the inner cavity of the connecting tube 41 is fixedly connected to a smoke sensor 43, and the surface of the connecting tube 41 is provided with an air inlet hole 44.

[0023] like Figure 1As shown, water is stored in the water tank 1, the protection box 2 protects the spray mechanism 3 and the transmission mechanism 5, and at the same time, the outside gas enters the connecting tube 41 through the air inlet 44, and the smoke sensor 43 detects the smoke in the gas and transmits data to the PLC controller 42. When the smoke content is higher than the preset value, the PLC controller 42 can start the water pump 31 to operate. The water pump 31 absorbs the water inside the water tank 1 and transmits it to the inner cavity of the hose 32 and the connecting pipe 33. The connecting pipe 33 transmits the water source to the inner cavity of the sprinkler head 34, and the sprinkler head 34 sprays the water source to the outside, thereby realizing the fire extinguishing operation. At the same time, the transmission mechanism 5 can drive the connecting pipe 33 and the sprinkler head 34 to move up and down, thereby expanding the spraying range and improving the fire extinguishing efficiency.

[0024] In this embodiment, Figure 2 As shown, the transmission mechanism 5 includes a servo motor 51, and the bottom of the servo motor 51 is fixedly connected to the bottom of the inner cavity of the protective box 2, the output shaft of the servo motor 51 is transmission-connected with a threaded rod 52, the surface of the threaded rod 52 is threadedly connected with a sleeve plate 53, and the connecting pipe 33 is located in the inner cavity of the sleeve plate 53 and is fixedly connected to the sleeve plate 53.

[0025] The back of the sleeve plate 53 is fixedly connected to a limiting rod 531 , and the back of the inner cavity of the protection box 2 is provided with a limiting groove 21 . One end of the limiting rod 531 extends to the inner cavity of the limiting groove 21 and is slidably connected to the inner cavity of the limiting groove 21 .

[0026] like Figure 2 As shown, the output shaft of the servo motor 51 drives the threaded rod 52 to rotate. During the rotation of the threaded rod 52, the sleeve plate 53 can be driven to move up and down. The sleeve plate 53 drives the limiting rod 531 to slide in the inner cavity of the limiting groove 21, thereby ensuring the stability of the sleeve plate 53 during movement. At the same time, the sleeve plate 53 drives the connecting pipe 33 and the sprinkler head 34 to move up and down, thereby expanding the sprinkler range and improving the fire extinguishing efficiency.

[0027] In this embodiment, Figure 1 As shown, a through slot 22 is opened on the left side of the protection box 2, and the connecting pipe 33 passes through the inner cavity of the through slot 22 and is slidably connected with the inner cavity of the through slot 22.

[0028] The top of the water storage tank 1 is connected to a water injection pipe 11 , and the top of the water injection pipe 11 is movably connected to a cover, and a water level window 12 is opened on the front of the water storage tank 1 .

[0029] like Figure 1 As shown, the connecting tube 33 can slide in the inner cavity of the through groove 22 when moving up and down, thereby preventing the connecting tube 33 from being misplaced during movement. At the same time, the sealing cover can be taken, and water can be injected into the water tank 1 through the water injection pipe 11, so that the water level inside the water tank 1 can be checked in real time through the water level window 12 when it is used later.

[0030] In this embodiment, Figure 4 As shown, the output end of the smoke sensor 43 is electrically connected to the input end of the PLC controller 42 , and the output end of the PLC controller 42 is electrically connected to the input ends of the servo motor 51 and the water pump 31 , respectively.

[0031] like Figure 4 As shown, the smoke sensor 43 can transmit the smoke detection data to the PLC controller 42 for analysis, and the PLC controller 42 can turn on or off the servo motor 51 and the water pump 31, thereby realizing automatic control and improving the convenience of use.

[0032] When in use, first, external gas enters the connecting tube 41 through the air inlet 44, and the smoke sensor 43 detects the smoke in the gas. At the same time, the detected data of the smoke sensor 43 will be transmitted to the PLC controller 42 for analysis. When the smoke content is higher than the preset value, the PLC controller 42 can transmit a signal to the water pump 31 to start the water pump 31. The water pump 31 absorbs the water inside the water tank 1 and transmits it to the inner cavity of the hose 32 and the connecting pipe 33. The connecting pipe 33 transmits the water source to the inner cavity of the sprinkler head 34, and the sprinkler head 34 sprays the water source to the outside, thereby realizing the fire extinguishing operation. At the same time, the PLC controller 42 starts the servo motor 51, and the output shaft of the servo motor 51 drives the threaded rod 52 to rotate. During the rotation of the threaded rod 52, the sleeve plate 53 can be driven to move up and down. The sleeve plate 53 can drive the connecting pipe 33 and the sprinkler head 34 to move up and down, thereby expanding the spraying range and effectively improving the fire extinguishing efficiency.
