[0027] An alarm 16 is installed on the left side of the bottom end of the installation shell 1, and a fixing rod 4 is fixedly connected at the four corners between the installation shell 1 and the installation plate 7. The threads on both sides of the outer side of the threaded rod 2 are opposite, and the top end of the movable rod 22 slides inside the limit groove 3, and the limit block 23 is embedded in the limit groove 24;

[0028] Specifically, Figure 1 and Figure 4 As shown, the connecting plate 21 at the top of the smoke sensor 15 is placed inside the mounting shell 1. After placing it, the servo motor 13 is started. The servo motor 13 drives the threaded rod 2 to rotate. Since the threaded rod 2 and the movable rod 22 cooperate with each other, and the limit block 23 is fixedly connected to the bottom end of one side of the movable rod 22, the rotation of the threaded rod 2 can make the limit block 23 embedded in the limit slot 24, so that the connecting plate 21 can be fixed to complete the installation of the smoke sensor 15. When disassembly is required, the servo motor 13 can be reversed, thereby facilitating the disassembly, replacement or maintenance of the smoke sensor 15, and preventing the use of bolts to install and disassemble, which will cause internal wear of the limit slot 24.

[0029] Embodiment 2: Mounting grooves 9 are provided at the four corners inside the mounting plate 7, mounting bolts 8 are provided inside the mounting grooves 9, guide grooves 19 are provided inside the protective shell 12, and support limit rods 18 are fixedly connected to both sides of the bottom end of the support plate 17, and the support limit rods 18 slide inside the guide grooves 19;

After alignment, the mounting bolts 8 are screwed into the mounting grooves 9 to fix the mounting plate 7. When the support plate 17 rotates, the support limit rod 18 will rotate inside the guide groove 19. The guide groove 19 can limit and guide the support plate 17 through the support limit rod 18. The support limit rod 18 can also support the support plate 17 and the components at the top of the support plate 17 to prevent the rotating shaft 20 from bending during use.

[0033] Working principle: When in use, the utility model puts the connecting plate 21 at the top of the smoke sensor 15 into the inside of the mounting shell 1, and then starts the servo motor 13. The servo motor 13 drives the threaded rod 2 to rotate. The rotation of the threaded rod 2 can make the limit block 23 embedded in the limit slot 24, so that the connecting plate 21 can be fixed to complete the installation of the smoke sensor 15. The mounting bolts 8 and mounting slots 9 inside the mounting plate 7 can facilitate the installation of the mounting plate 7 on the wall panel, so that the mounting slots 9 inside the mounting plate 7 are aligned with the mounting slots 9 on the wall panel. After alignment, screw the mounting bolts 8 into the mounting slots 9 to fix the mounting plate 7. When the smoke sensor 15 senses smoke, the alarm 16 will sound an alarm to notify nearby personnel, and the camera 6 can observe the smoke and the surrounding situation, which is convenient for the staff to timely Understand the situation of the fire location to facilitate rescue and fire extinguishing by the staff. When the camera 6 is working, start the electric push rod 5 and the drive motor 14. The electric push rod 5 makes one side of the camera 6 rise and fall to adjust the angle of the camera 6. The drive motor 14 can drive the camera 6 to rotate through the rotating shaft 20. When the support plate 17 rotates, the support limit rod 18 will rotate inside the guide groove 19. The guide groove 19 can limit and guide the support plate 17 through the support limit rod 18. The support limit rod 18 can also support the support plate 17 and the components at the top of the support plate 17 to prevent the rotating shaft 20 from bending during use. When the smoke sensor 15 needs to be disassembled for inspection, the servo motor 13 can be reversed, thereby facilitating the disassembly, replacement or inspection of the smoke sensor 15 and preventing the use of bolts to install and disassemble, which will cause internal wear of the limit slot 24.
