[0022] As shown in the attached Figure 1-6 A campus fire warning device shown in the figure includes a mounting plate 1. A mounting seat 2 is fixedly arranged at the bottom of the mounting plate 1. A warning device housing 3 is installed at the bottom of the mounting seat 2. A microcontroller 16, a smoke sensor 17 and a temperature sensor 18 are installed inside the warning device housing 3. A warning light 19 is arranged at the bottom of the warning device housing 3, and a buzzer 20 is arranged on the surface of the warning device housing 3. The smoke sensor 17, the temperature sensor 18, the warning light 19 and the buzzer 20 are all electrically connected to the microcontroller 16.

[0023] Specifically, in this structure, the fire warning device is installed at the positions on campus that require fire warning, such as public areas like classrooms, corridors, or dormitories. Once a fire occurs, first, the smoke sensor 17 and the temperature sensor 18 detect the smoke and temperature conditions of the fire in real time and send the signals to the microcontroller 16. The microcontroller 16 sends instructions to the warning light 19 and the buzzer 20. The warning light 19 flashes to prompt the campus personnel, and at the same time, the buzzer 20 gives an early warning to remind the campus personnel to evacuate in time, thus achieving the effect of fire warning.

[0024] In a specific embodiment, as shown in Figure 1 , 2 , 3, 4, and 5, a plurality of locking structures are provided between the mounting base 2 and the warning device housing 3. The locking structure includes a locking block 4. The locking block 4 is fixedly installed on the surface of the mounting base 2. An installation frame 5 is fixedly provided on the surface of the warning device housing 3. An extension plate 6 is slidably arranged inside the installation frame 5. One end of the extension plate 6 is provided with a support block 7. A locking frame 8 is rotatably arranged outside the support block 7. A limiting slide plate 9 is arranged at the bottom of the extension plate 6 inside the installation frame 5. Two tension springs 10 are arranged at the bottom of the limiting slide plate 9. The two ends of the tension springs 10 are respectively connected to the bottom of the inner cavity of the installation frame 5 and the bottom of the limiting slide plate 9. A locking bar 13 is fixedly installed at the top of the inner cavity of the locking frame 8. A locking groove 14 is opened on the upper surface of the locking block 4. The locking bar 13 and the locking groove 14 are adapted in structure. The bottom of the locking frame 8 is at both ends of the support block 7. A pin 15 is arranged at the connection between the locking frame 8 and the support block 7, and they are rotatably connected through the pin 15.

[0025] Specifically, in this structure, it is convenient for quick disassembly and assembly between the warning device housing 3 and the mounting base 2. Specifically, when installing the fire warning device, first, the warning device housing 3 and the mounting base 2 are docked. At the same time, by pulling up the locking frame 8 to stretch the locking frame 8 towards the locking block 4, at this time, the extension plate 6 drives the limiting slide plate 9 to slide inside the installation frame 5 and stretches the tension springs 10. After the locking frame 8 approaches the position of the locking block 4, the locking frame 8 is rotated with the support block 7 through the pin 15, so that the locking frame 8 is sleeved outside the locking block 4, and the tension springs 10 are reset after being stretched, providing a force in the opposite direction of the locking block 4 to the locking frame 8, realizing the connection between the locking frame 8 and the locking block 4, and further being able to connect the warning device housing 3 and the mounting base 2, avoiding the tediousness of using bolt connection during disassembly and assembly;

[0026] When the locking frame 8 is sleeved outside the locking block 4, it can make the locking bar 13 snap into the inside of the locking groove 14, thereby preventing the locking frame 8 from falling off the outside of the locking block 4 and further improving the connection effect;

[0027] Similarly, when the warning device needs to be disassembled, pull the locking frame 8 upward and rotate the locking frame 8 relative to the support block 7 to separate the locking frame 8 from the locking block 4, thereby enabling the quick disassembly of the warning device.

[0028] In a specific embodiment, as shown in the appended Figure 1 figures, a plurality of mounting holes are formed on the surface of the mounting plate 1, and mounting bolts 11 are threadedly installed inside the plurality of mounting holes.

[0029] Specifically, in this structure, the mounting plate 1 can be installed at a specific use position, such as the surface of the ceiling or wall, through the mounting bolts 11, thereby facilitating the installation and fixation of the warning device.

[0030] In a specific embodiment, as shown in the appended Figure 1 and 2 figures, a plurality of rectangular openings are formed on the surface of the warning device housing 3, and dust-proof nets 12 are embedded inside the plurality of rectangular openings.

[0031] Specifically, in this structure, the rectangular openings can not only facilitate the detection of fire smoke but also serve the purpose of heat dissipation, while the dust-proof nets 12 prevent dust from entering the interior of the warning device and affecting its use.

[0032] Working principle of the present utility model:

[0033] This application provides a campus fire warning device. During specific operation, first, the mounting plate 1 can be installed at the position of the wall or ceiling through the mounting bolts 11, thereby realizing the installation of the mounting seat 2;

[0034] When installing the warning device, dock the warning device housing 3 with the mounting seat 2. At the same time, by pulling the locking frame 8 upward and stretching the locking frame 8 towards the locking block 4, the extension plate 6 drives the limit sliding plate 9 to slide inside the mounting frame 5 and stretches the tension spring 10. When the locking frame 8 approaches the position of the locking block 4, rotate the locking frame 8 relative to the support block 7 through the pin 15 so that the locking frame 8 sleeves outside the locking block 4. After being stretched, the tension spring 10 resets and provides a force in the opposite direction of the locking block 4 to the locking frame 8, realizing the connection between the locking frame 8 and the locking block 4. Furthermore, the warning device housing 3 can be connected to the mounting seat 2. When the locking frame 8 sleeves outside the locking block 4, the locking bar 13 can be inserted into the locking groove 14, thereby preventing the locking frame 8 from falling off outside the locking block 4 and further improving the connection effect, thus realizing the installation of the warning device and avoiding the cumbersome process of using bolt connection during disassembly and assembly;

[0035] When a fire warning is carried out, first, the smoke sensor 17 of model MQ-2 and the temperature sensor 18 of model PT100 detect the smoke and temperature conditions of the fire in real time, and send the signals to the microcontroller 16. The microcontroller 16 sends instructions to the warning light 19 and the buzzer 20. The warning light 19 flashes to prompt the campus personnel, and at the same time the buzzer 20 gives a warning to remind the campus personnel to evacuate in time, so as to achieve the effect of fire warning;

[0036] When disassembling the warning device, pull up the locking frame 8 and rotate the locking frame 8 relative to the support block 7 so that the locking frame 8 is separated from the locking block 4, then the disassembly operation of the warning device can be realized quickly, which is convenient for cleaning the dust screen 12 on the outer shell 3 of the warning device.

[0037] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
