DETAILED DESCRIPTION

[0017] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0018] like Figures 1 to 6 As shown, a fire detection and alarm device for smart firefighting includes a base plate 1, a support plate 2, and an alarm device body 3. The base plate 1 is fixed to the wall by a plurality of countersunk bolts 4. A positioning groove 5 is provided at the center of the front end of the base plate 1. A magnet 6 is fixed in the rear end of the positioning groove 5. Slide grooves 7 are provided on both the left and right sides of the upper and lower parts of the front end of the base plate 1 along the left and right directions. Slide blocks 8 are slidably provided on the slide grooves 7. A spring 9 is fixed on the front end of the slide block 8 along the front and rear directions. The front ends of the two springs 9 on the same side are fixedly connected to the same pressure plate 10. A locking plate 11 is fixed to the upper part of the front end of the pressure plate 10. A first threaded hole 12 is provided on the locking plate 11. A limit plate 13 is fixed to the position of the upper middle section of the front end of the base plate 10 near the corresponding slide groove 7. The limit plate 13 has a second threaded hole 14. The alarm device body 3 is fixed on the front center of the support plate 2, and a magnetic plate 15 is fixed on the rear center of the support plate 2. The support plate 2 abuts on the front end of the base plate 1. The magnetic plate 15 is inserted into the positioning groove 5 and is magnetically connected to the magnet 6. The pressure plate 10 abuts on the front end of the support plate 2 on the same side and the spring 9 is in a stretched state. The first threaded hole 12 corresponds coaxially to the adjacent second threaded hole 14 and is threaded with the same butterfly bolt 16.

[0019] During installation and use, the base plate 1 can be first fixed to the use position by the countersunk bolts 4. Then, the support plate 2 is abutted against the base plate 1, and the magnetic plate 15 is aligned and inserted into the positioning groove 5, so that the magnetic plate 15 is magnetically connected to the magnet 6, and the initial positioning installation of the support plate 2 can be achieved. Next, pull the pressure plate 10 to the front side so that the distance between the pressure plate 10 and the base plate 1 is greater than the thickness of the support plate 2. At this time, the spring 9 has a certain amount of stretching. Then move the pressure plate 10, and with the cooperation of the corresponding slider 8 and the slide groove 7, move the pressure plate 10 to the front of the support plate 2 and then release the pressure plate 10. Under the action of the reset elastic force of the spring 9, the pressure plate 10 can be automatically pressed on the support plate 2, thereby achieving further compression and limiting installation of the support plate 2, and at this time, the first threaded hole 12 can be aligned with the corresponding second threaded hole 14. Afterwards, screw the butterfly bolt 16 into place on the first threaded hole 12 and the second threaded hole 14 to lock the pressure plate 10 and prevent it from moving. This completes the fixed installation of the entire alarm device body 3, and the installation is stable and does not affect subsequent use. When the alarm device body 3 needs to be repaired or replaced, the butterfly bolt 16 that is convenient for manual operation can be unscrewed first, and then the pressure plate 10 can be pulled forward to make the pressure plate 10 leave the support plate 2 and then move the pressure plate 10 back to its position to release the clamping limit on the support plate 2. Then, the magnetic plate 15 can be pulled forward to remove the original alarm device body 3, and then the new alarm device body 3 can be installed as described above. In this way, the alarm device body 3 can be flexibly and conveniently disassembled, assembled and replaced. The overall operation is simpler and more convenient, saving time and effort, and will not cause damage to the original installation position. It is convenient to continue to install and use it in the original position, which is more convenient and practical. The magnetic plate 15 can be made of existing conventional iron or other magnetic metal materials.

[0020] In this embodiment, the alarm device body 3 includes a support column 17 fixedly arranged on the front center of the support plate 2 along the front-to-back direction, and a plurality of evenly distributed first electric push rods 18 are embedded on the rear end circumference of the support column 17, and a second electric push rod 19 is coaxially embedded at the front end. The telescopic end of the first electric push rod 18 is fixedly connected to the smoke alarm 20, and the telescopic end of the second electric push rod 19 faces forward and is fixedly connected to a dustproof mesh cover 21, which abuts against the front end of the support plate 2. A controller 22, a GPS locator 23, and a wireless communication module 24 are fixedly mounted on the front end of the support plate 2 inside the dust screen 21. The first electric push rod 18, the second electric push rod 19, the smoke alarm 20, the GPS locator 23, and the wireless communication module 24 are all electrically connected to the controller 22. This allows the dust screen 21 to effectively shield the corresponding components from dust during use, ensuring the service life of the corresponding components and making the device more practical as a whole. The smoke concentration sensor inside the smoke alarm 20 can detect the smoke concentration at the operating location in real time and feed the information back to the controller 22. When a fire occurs and the smoke concentration received by the controller 22 exceeds a set value, the controller 22 can first automatically control the second electric push rod 19 to extend its telescopic end, driving the dust screen 21 forward an appropriate distance, and then automatically control the first electric push rod 18 to reciprocate its telescopic end, driving the corresponding smoke alarm 20 to reciprocate. At the same time, the controller 22 can automatically control the operation of the sound and light alarm components on the smoke alarm 20, providing sound and light alarm prompts. This, combined with the circumferential distribution of the multiple smoke alarms 20 and the reciprocating motion of each smoke alarm 20, can significantly enhance the effectiveness of the warning. Furthermore, the controller 22 can automatically control the GPS locator 23 for positioning and transmit relevant fire information and location information to the terminal via the wireless communication module 24, further facilitating timely and accurate arrival of personnel at the fire location for handling. The first electric push rod 18, the second electric push rod 19, the smoke alarm 20, the controller 22, the GPS locator 23, and the wireless communication module 24 can all utilize existing technologies. During actual use, the controller 22 is electrically connected to an external power source to power the corresponding components. The controller 22 is wirelessly connected to the terminal via the wireless communication module 24 to facilitate remote information transmission.

[0021] In this embodiment, the magnetic plate 15 is matched with the positioning groove 5 to ensure that the magnetic plate 15 is smoothly inserted into place.

[0022] In this embodiment, a handle 25 is fixedly provided on the front end of the pressing plate 10 to facilitate controlling the movement of the pressing plate 10 .

[0023] In this embodiment, the base plate 1 and the support plate 2 are both foam aluminum plates. Foam aluminum is an existing material with the performance characteristics of high damping energy absorption and shock absorption. It can play a good buffering and shock absorption role in actual use and is more conducive to ensuring the service life of the device.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
