[0002] Firefighting means eliminating hidden dangers and preventing disasters (i.e. preventing and solving man-made, natural and accidental disasters encountered by people in their lives, work and studies). Of course, the meaning of firefighting in the early stage of people's cognition is: (extinguishing) the meaning of fire. Most of the existing firefighting equipment uses wireless smoke detectors, which can sense fires without human supervision. Then, the wireless smoke detectors transmit signals and receive signal feedback to realize functions such as automatic fire alarm, fire safety linkage and personnel evacuation. Among them, the existing wireless smoke detectors are mostly installed at high places during installation.

[0029] In this embodiment, the device can be easily installed by providing the mounting plate 17 and the mounting holes.

[0030] Working principle: when the wireless smoke detector 9 needs to be installed, the staff fixes the box body 1 in the designated position through the mounting plate 17, mounting holes and screws. Then, the staff moves the vertical plate 6 so that the vertical plate 6 drives the rectangular plate 503 and the L-shaped plate 8 to be inserted into the inner cavity of the rectangular groove 3. At the same time, the vertical plate 6 and the L-shaped plate 8 are vertically downward. Then, the staff rotates and moves the limiting bolts 13 on both sides in turn so that the limiting bolts 13 are threadedly inserted into the inner cavity of the threaded pin groove 12, thereby realizing the installation of the rectangular block 7 and the rotating shaft 2. Then, the staff moves the L-shaped plate 8 so that the L-shaped plate 8 slides on the outer surface of the vertical plate 6. When the L-shaped plate 8 slides to the appropriate installation position, the staff rotates the limiting nuts 15 on both sides in turn so that the limiting nuts 15 are tightly fitted at the connection between the outer surface of the stud 14 and the L-shaped plate 8, thereby realizing the installation of the L-shaped plate 8 and the vertical plate 6. Then, the staff installs the wireless smoke detector 9 and the L-shaped plate 8 through screws.

[0031] Then, the staff energizes the servo motor 501 plug and starts the external controller of the servo motor 501, so that the output end of the servo motor 501 drives the screw 502 to rotate on the inner surface of the rectangular plate 503. At the same time, the rectangular plate 503 drives the tooth plate 504 to move rightward, so that the tooth plate 504 drives the gear 4 to rotate 90 degrees counterclockwise. At the same time, the gear 4 drives the shaft 2 to rotate 90 degrees counterclockwise, and the shaft 2 drives the rectangular block 7 and the vertical plate 6 to rotate 90 degrees counterclockwise, so that the vertical plate 6 drives the L-shaped plate 8 and the wireless smoke detector 9 to rotate 90 degrees counterclockwise, so that the wireless smoke detector 9 moves to the specified installation height, thereby completing the installation of the wireless smoke detector 9;

[0032] When the wireless smoke detector 9 has been used for a period of time and needs to be disassembled and replaced, the staff starts the external controller of the servo motor 501 again, so that the output end of the servo motor 501 drives the screw 502 to rotate in the reverse thread on the inner surface of the rectangular plate 503. At the same time, the rectangular plate 503 drives the toothed plate 504 to move left, so that the toothed plate 504 drives the gear 4 to rotate 90 degrees clockwise. At the same time, the gear 4 drives the rotating shaft 2 to rotate 90 degrees clockwise, and the rotating shaft 2 drives the rectangular block 7 and the vertical plate 6 to rotate 90 degrees clockwise, so that the vertical plate 6 drives the L-shaped plate 8 and the wireless smoke detector 9 to rotate 90 degrees clockwise, so that the wireless smoke detector 9 moves to the bottom, so that it is convenient for the staff to disassemble and replace the wireless smoke detector 9. The device is simple to operate and easy to disassemble and replace, thereby effectively reducing the difficulty of later replacement and maintenance, as well as the disassembly and assembly cost, so as to meet the customer's usage needs.
