[0045] Working principle:

[0046] The smoke sensor 12 and the temperature sensor 13 are started by the controller 15. If the smoke sensor 12 detects smoke, it indicates that a fire has occurred. The smoke sensor 12 cooperates with the controller 15 to start the sound and light alarm 14, and the sound and light alarm 14 sends out an alarm, thereby achieving the purpose of timely discovering a fire. Similarly, if the temperature sensor 13 detects that the temperature rises, it also indicates that a fire has occurred. The temperature sensor 13 cooperates with the controller 15 to start the sound and light alarm 14, and the sound and light alarm 14 sends out an alarm, thereby achieving the purpose of timely discovering a fire. Compared with the existing method, the present invention replaces the existing manual patrol fire method, can timely discover a fire and send out an early warning signal, and uses the smoke sensor 12 and the temperature sensor 13 to perform dual monitoring of the fire, thereby improving the sensitivity of fire monitoring, reducing the false alarm rate of fire monitoring, and meeting the existing needs.

[0047] And by starting the motor 6, the motor 6 will drive the screw rod 7 to work, and under the drive of the screw rod 7, the sleeve 8 will move on the screw rod 7. When the sleeve 8 moves, the smoke sensor 12 and the temperature sensor 13 will move up and down, so that they can monitor the air temperature at different heights and the smoke in the air, further improving the sensitivity of fire monitoring and reducing the false alarm rate of fire monitoring;

[0048] The limiting ring 20 is rotated by an external tool (screwdriver) to disengage the limiting ring 20 from the outer wall of the threaded column 19, and then the threaded column 19 is taken out from the first connecting hole 16 and the second connecting hole 17, so as to achieve the purpose of disassembling and separating the connecting seat 10 and the mounting plate. Therefore, the present invention facilitates the maintenance of the smoke sensor 12, the temperature sensor 13, and the sound and light alarm 14;

[0049] And by pulling the pull rod 32, the pull rod 32 drives the fixing rod 30 to move in the movable hole 28, and at this time the spring 33 will perform a corresponding stretching movement. After one end of the fixing rod 30 is disengaged from the inside of the clamping hole 29, the fixing of the first protective cover 21 and the second protective cover 23 can be released, and then the first protective cover 21 and the second protective cover 23 can be manually driven to be disassembled and separated, so as to facilitate the maintenance of the controller 15 and the power supply 34;

[0050] And by placing the second protective cover 23 on the top of the first protective cover 21, the limit block 24 will be stuck in the limit groove 22, and the fixing bar 27 will also be located in the fixing groove 26, and then the fixing rod 30 will be driven to move in the movable hole 28 under the action of the spring 33. After one end of the fixing rod 30 is stuck in the clamping hole 29, the first protective cover 21 and the second protective cover 23 can be fixed. With the cooperation of the first protective cover 21 and the second protective cover 23, the controller 15 and the power supply 34 can be protected to prevent the controller 15 and the power supply 34 from being damaged by external influences, thereby improving the working efficiency and service life of the controller 15 and the power supply 34.
