The limiting cavity 23 is fixedly connected to a limiting spring 24, and the other end of the limiting spring 24 is fixedly connected to the T-shaped limiting rod 22. Since the clamping end of the T-shaped limiting rod 22 is arranged in an arc shape, the T-shaped limiting rod 22 is squeezed into the limiting cavity 23 when the T-shaped connecting seat 3 moves upward, and the limiting spring 24 is compressed at this time. When the T-shaped limiting rod 22 moves to the position of the clamping hole 11, under the elastic force of the limiting spring 24, the T-shaped limiting rod 22 is clamped into the clamping hole 11, and the T-shaped connecting seat 3 is limited and fixed; The pulling mechanism includes a telescopic cylinder 21, which is fixedly installed in the mounting base 1. The output ends of the telescopic cylinder 21 are respectively fixedly connected to two traction ropes 19, and the ends of the two traction ropes 19 away from the telescopic cylinder 21 are respectively fixedly connected to the first baffle 7 and the second baffle 15. When the smoke sensors 20 arranged on both sides of the mounting base 1 detect smoke, the telescopic cylinder 21 will start to drive the two traction ropes 19 connected to its output ends to move, and the movement of the two traction ropes 19 drives the first baffle 7 and the second baffle 15 connected thereto to start moving. When the first baffle 7 is moved out of the gas guide cavity 35, the high-pressure carbon dioxide gas in the carbon dioxide gas cylinder 2 will enter the connecting cavity 4 through the gas guide cavity 35; The spray mechanism includes a water guide cavity 26, which is opened in the mounting seat 1. One end of the water guide cavity 26 is connected to the external threaded connecting pipe 17, and the other end is connected to the second annular cavity 16.

When the second baffle 15 is pulled by the traction rope 19, it will be stored in the second storage cavity 18. At this time, the external threaded connecting pipe 17 connected to the external water pipe will guide the water source into the water guide cavity 26, and the water source entering the water guide cavity 26 will enter the second annular cavity 16. The water source entering the second annular cavity 16 will enter the plurality of nozzles 14 in turn and spray around the device to extinguish the fire source around the device, so as to prevent the fire source around the device from causing damage to the device; The second baffle 15 is fixed in the water guiding cavity 26 by sealing glue, and the second baffle 15 is fixed in the water guiding cavity 26 by sealing glue to block the water source.

[0023] In addition, in order to achieve the above-mentioned purpose, the present invention also provides a method of use for the above-mentioned automatic fire alarm device for smart fire fighting, comprising: S1 The mounting base 1 is fixed on a suitable wall surface by installing the screw rod 10. When the smoke sensor 20 detects smoke, the telescopic cylinder 21 is activated to move the first baffle 7 and the second baffle 15. After the first baffle 7 is moved out of the air guide cavity 35, the high-pressure carbon dioxide gas in the carbon dioxide gas cylinder 2 enters the connecting cavity 4. The movement of the T-shaped connecting base 3 drives the cone plate 34 to move. The cone plate 34 moves upward to break the plastic sheet 8. S2 When the T-shaped limit rod 22 moves to the position of the clamping hole 11, the T-shaped limit rod 22 is clamped into the clamping hole 11 to fix the T-shaped connecting seat 3. When the smoke sensor 20 senses smoke, the LED alarm light 31 will flash, the alarm speaker 33 will emit an alarm tone, and the communication module 12 will send a fire alarm signal to the terminal. The operator can control the camera 32 after receiving the signal. S3 The air entering the connecting chamber 4 will enter the guiding chamber 9, and finally be discharged into the external environment through a plurality of air holes 29 opened on the outside of the supporting tube 30. When the second baffle 15 is retracted into the second receiving chamber 18, the external threaded connecting tube 17 will guide the water source into the water guiding chamber 26. The water source entering the water guiding chamber 26 will enter into a plurality of nozzles 14 in turn and be sprayed around the device.

[0024] Working principle: when in use, the mounting base 1 is fixed on a suitable wall by installing the screw rod 10. When the smoke sensors 20 arranged on both sides of the mounting base 1 detect smoke, the telescopic cylinder 21 will start to drive the two traction ropes 19 connected to its output end to move. The movement of the two traction ropes 19 drives the first baffle 7 and the second baffle 15 connected thereto to start moving. When the first baffle 7 is moved out of the air guide cavity 35, the high-pressure carbon dioxide gas in the carbon dioxide gas cylinder 2 will enter the connecting cavity 4 through the air guide cavity 35. The gas entering the connecting cavity 4 will push the T-shaped connecting base 3 to move upward along the connecting cavity 4. The movement of the T-shaped connecting base 3 drives the cone plate 34 to move. The cone plate 34 moves upward to break the plastic sheet 8. The camera 32, the alarm speaker 33 and the LED alarm light 31 are extended into the external environment. At the same time, since the clamping end of the T-shaped limit rod 22 is arranged in an arc shape, the T-shaped limit rod 22 is squeezed into the limit cavity 23 when the T-shaped connecting seat 3 moves upward. At this time, the limit spring 24 is compressed. When the T-shaped limit rod 22 moves to the position of the clamping hole 11, under the elastic force of the limit spring 24, the T-shaped limit rod 22 is clamped into the clamping hole 11 to limit and fix the T-shaped connecting seat 3. At the same time, when the smoke sensor 20 senses smoke, the LED alarm light 31 will flash, the alarm speaker 33 will emit an alarm tone, and the communication module 12 will send a fire alarm signal to the terminal. After receiving the signal, the operator can control the camera 32 to observe the fire situation; When the T-shaped limiting rod 22 is clamped into the clamping hole 11 to limit the T-shaped connecting seat 3, the connecting hole 27 will be aligned with the guiding cavity 9. At this time, the air entering the connecting cavity 4 will enter the guiding cavity 9, and the air in the guiding cavity 9 will enter the first annular cavity 28, and finally be discharged into the external environment through a plurality of air holes 29 opened on the outside of the supporting tube 30. The carbon dioxide gas discharged through the air holes 29 will disperse the surrounding smoke, preventing a large amount of smoke from gathering around the device, so that the light emitted by the LED warning light 31 is blocked, and it is impossible to remind and guide people in the distance; When the second baffle 15 is pulled by the traction rope 19, it will be retracted into the second storage chamber 18. At this time, the external threaded connecting pipe 17 connected to the external water pipe will guide the water source into the water guiding chamber 26. The water source entering the water guiding chamber 26 will enter the second annular chamber 16. The water source entering the second annular chamber 16 will enter several nozzles 14 in turn and spray around the device to extinguish the fire source around the device and prevent the fire source around the device from causing damage to the device.
