In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

As shown in fig. 1-3, the utility model provides a fire-fighting emergency alarm device, which comprises a wireless fire-fighting alarm system and a protection structure for protecting the wireless fire-fighting alarm system. Specifically, the protection structure includes a case 10, a guide bar 20, a moving box 30, a spring 40, a driving device 50, and a connection bar 60.

The housing 10 is fixedly installed on a wall of a building, and an opening 11 is formed in an inner cavity of the housing 10 at one side of the housing 10. The cover 12 is disposed on the side of the box 10, the upper end of the cover 12 is hinged to the upper end of the box 10, the lower end of the cover 12 is a free end, and the opening 11 can be closed when the lower end of the cover 12 is attached to the lower end of the box 10. The guide rod 20 is installed in the box body 10, and both ends of the guide rod are respectively fixedly connected with both sides of the box body 10. The movable box 30 is disposed in the box 10, the movable box 30 has a sliding sleeve 31, and the sliding sleeve 31 is sleeved on the guide rod 20 and slidably connected with the guide rod 20, so that the movable box 30 can slide back and forth along the extending direction of the guide rod 20. Each part of wireless fire alarm system all installs in removing box 30, and the spring 40 cover is established on guide bar 20, and the one end and the box 10 butt of spring 40, the other end and sliding sleeve 31 butt, spring 40 make remove box 30 have the trend that is close to uncovered 11.

The driving means 50 is used to pull the moving box 30 so as to move the moving box 30 away from the opening 11. The driving device 50 comprises a motor 51 and a steel wire rope 52, the motor 51 is fixedly installed in the box 10 and located at the other side of the box 10, the motor 51 is electrically connected with a host in the wireless fire-fighting alarm system, and a winding drum 511 is installed on an output shaft of the motor 51. The motor 51 is preferably a motor 51 with a braking function, i.e. when the power is off, the output shaft of the motor 51 will not rotate under the action of external force. One end of the wire rope 52 is connected to the movable box 30, and the other end is connected to the winding drum 511 on the output shaft of the motor 51.

One end of the connecting rod 60 is hinged with one side of the movable box 30 close to the opening 11, and the other end is hinged with the inner side of the cover 12.

The specific working process is as follows: when a fire occurs, the temperature sensor 70 and the smoke sensor 80 in the wireless fire alarm system detect the fire and send signals to the host computer, and the host computer receives the signals, immediately and circularly makes calls to a plurality of people uninterruptedly and carries out remote voice alarm. Meanwhile, the host computer controls the motor 51 to rotate, so that the winding drum 511 on the output shaft of the motor 51 starts to wind the cable 52, and the movable box 30 is gradually far away from the opening 11 under the pulling of the cable 52. Under the effect of connecting rod 60, lid 12 finally can be closed with uncovered 11 of box 10 for wireless fire alarm system is protected in box 10, just can not just be burnt out in the short time when consequently the condition of a fire takes place, and then the time of extension host computer dialing makes alarm information can last to remind the user effectively.

In one embodiment, the temperature sensor 70 and the smoke sensor 80 of the wireless fire alarm system are both fixedly installed at one side of the mobile box 30 near the opening 11. After the box 10 is fixedly installed on the wall of the building, the temperature sensor 70 and the smoke sensor 80 can detect the fire in the nearby environment more quickly and better due to the proximity of the opening 11.
