[0013] The beneficial effects of the present invention are:

[0014] (1) The door body can be rolled up by the provided rolling door mechanism, and the provided guide mechanism can drive the rolling door mechanism to roll up the door body. When a fire occurs, the guide mechanism directly drives the rolling door mechanism to roll up the door body, and the provided lifting mechanism drives the guide mechanism to work; the provided transmission mechanism transmits the kinetic energy of the lifting mechanism to the water spraying mechanism, and the water spraying mechanism squeezes the water flow inside the water tank, so that the water flow is sprayed out from the inside of the nozzle after being pressurized, thereby achieving the effect of extinguishing the fire. The provided winch rotates to drive the transmission shaft to rotate, and when the transmission shaft rotates, it drives the first gear to rotate. At this time, the first gear is not on the same plane as the second gear, and the first gear rotates by itself; at this time, the protection rod drives the door body to roll up, so that the door body opens, making it easier for firefighters to enter the room to extinguish the fire.

[0015] (2) The second gear is meshed with the first gear as the lifting mechanism pushes it, so that the rotation of the second gear can drive the rotation of the first gear. When the first gear rotates, the door body is rolled up, and the door body is opened, which is convenient for people in the room to evacuate quickly and for firefighters outside to extinguish the fire. When the second gear rotates, the top block on the side wall of the second gear will abut the rotating plate, and multiple top blocks will continuously squeeze the rotating plate, so that the rotating plate will continuously rotate and reset, so that the rotating plate drives the hammer to make a ringing sound, thereby achieving the effect of an alarm. When the first motor rotates, the first motor drives the threaded rod to rotate, and the second gear moves forward under the cooperation of the threaded rod and the thread groove. When the second gear moves to the guide groove and contacts the guide block, the second gear moves the bare rod section on the threaded rod where no thread is set.

When the first motor rotates, the threaded rod rotates synchronously. At this time, the worm rotates synchronously with the threaded rod, and the turbine meshing with the worm arranged on the side wall of the worm rotates synchronously, thereby driving the transmission mechanism to transfer kinetic energy to the water spraying mechanism for spraying water.

[0016] (3) The rotating plate is continuously rotated with the continuous squeezing of the top block, and then the hammer on the side wall of the rotating plate will continuously hit the sound board, and the sound board will continuously make a sound. The sound of the sound board can quickly spread the sound through the amplifying chamber and the loudspeaker, so as to make an alarm sound. The turbine is driven by the worm to rotate, and the rotating rod connected to the turbine rotates. When the rotating rod rotates, the rotating rod drives the rotating wheel to rotate synchronously, and the rotating wheel pushes the tooth plate to move inside the water tank. The rotating wheel drives the tooth plate to move. When the tooth plate moves, the tooth plate drives the squeezing plate to move downward. When the squeezing plate moves downward, the squeezing plate squeezes the water below it, and then the water is squeezed into the inside of the water pipe. When the pressure inside the water pipe increases, the nozzle will be opened, so that water is sprayed out from the inside of the nozzle, which plays a certain cooling and fire extinguishing function, can provide certain favorable conditions for firefighters to extinguish fires, and achieve good fire safety effects.
