A rolling shutter door 3 is wound around the middle of the winding roller 2. By rotating the winding roller 2, the rolling shutter door 3 can be wound and unwound, which is convenient for opening and closing. One end of the rolling shutter door 3 penetrates through the bottom of the winding box 1 and is fixedly connected with a limiting strip 13. An electric push rod 14 is arranged in the inner cavity of the limiting strip 13. The output end of the electric push rod 14 is connected with a push plate 15. The limiting strip 13 can limit the up and down movement of one end of the rolling shutter door 3, improving the stability of the rolling shutter door 3;

[0026] On one side of the electric push rod 14, there is a fire extinguisher cylinder body 16. On the side of the fire extinguisher cylinder body 16 close to the push plate 15, there is a fire extinguisher pressing plate 17. At the opening on one side of the limiting strip 13, there is a cover plate 19. At both ends of the cover plate 19, there are symmetrically arranged fire extinguisher nozzles 18 connected to the fire extinguisher cylinder body 16. By placing the fire extinguisher cylinder body 16 in the middle of the limiting strip 13 and making the push plate 15 fit with the fire extinguisher pressing plate 17, when fire extinguishing is needed, the electric push rod 14 can be started to control the push plate 15 to squeeze the fire extinguisher pressing plate 17, so that the fire extinguishing smoke inside the fire extinguisher cylinder body 16 is ejected through the fire extinguisher nozzles 18, realizing the function of fire extinguishing. The cover plate 19 protects the fire extinguisher cylinder body 16 and the electric push rod 14 and is convenient to open through the cover plate 19 for replacing the fire extinguisher cylinder body 16. Among them, the fire extinguisher cylinder body 16, the fire extinguisher pressing plate 17, and the fire extinguisher nozzles 18 are existing components of an existing fire extinguisher body and will not be elaborated here;

[0027] On one side of the inner cavity of the winding box 1, there is a driving mechanism. On the other side, there is a liquid pump 4 and a controller 5. The input end of the liquid pump 4 is connected with a connector 11, and the output end is connected with a water pipe 6. At the bottom of the winding box 1, there are a water spraying pipe 7, a temperature sensor 9, a smoke sensor 10, and a limiting door frame 12. On one side of the water spraying pipe 7, there are spray holes 8. Starting the driving mechanism can control the rotation of the winding roller 2, and by starting the liquid pump 4, the liquid inside the water tank is input into the water pipe 6 through the connector 11 and sprayed out through the spray holes 8 on one side of the water spraying pipe 7 to cool the surface of the rolling shutter door 3, improving the fireproof effect. The temperature sensor 9 and the smoke sensor 10 can detect temperature and smoke, improving the use effect.

[0028] As shown in the appendix Figure 3 As shown in the figure, the bottom of the water pipe 6 is connected with the inner cavity of the water spraying pipe 7 through a communicating pipe. The spray holes 8 are arranged on the side of the water spraying pipe 7 close to the limiting strip 13. The liquid input into the water pipe 6 can be input into the water spraying pipe 7 and sprayed out through the spray holes 8, realizing the function of cooling and extinguishing fire and improving the fireproof effect on the rolling shutter door 3.

[0029] As shown in the appendix Figures 1-3As shown in the figure, there are two limit door frames 12, which are symmetrically arranged on both sides of the rolling shutter door 3. The fire extinguisher nozzle 18 and the cover plate 19 are arranged on the side close to the smoke sensor 10. The push plate 15 corresponds to the fire extinguisher pressing plate 17. The movement of the rolling shutter door 3 is limited by the limit door frame 12 to improve the movement stability of the rolling shutter door 3. And the fire extinguishing smoke ejected by the fire extinguisher nozzle 18 can extinguish the fire at the bottom of the fire part to improve the fire extinguishing effect.

[0030] As shown in the attached Figure 1 、 3 As shown in Figure 4, there are a plurality of electric push rods 14 and fire extinguisher cylinders 16 arranged in the middle of the limit strip 13. A sub-controller 20 is arranged on the inner side of the winding box 1 away from the controller 5. The push plate 15 is controlled by the electric push rod 14 to squeeze the fire extinguisher pressing plate 17, which is convenient for using the fire extinguisher cylinder 16.

[0031] As shown in the attached Figure 2 、 5 As shown in the figure, the driving mechanism includes a stepping motor 22 arranged on one side of the sub-controller 20. The output end of the stepping motor 22 is connected with a threaded rod 23. A moving plate 24 is sleeved on the middle thread of the threaded rod 23. A tooth hole 21 is opened at one end of the winding roller 2 close to the stepping motor 22.

[0032] As shown in the attached Figure 2 、 5 As shown in the figure, a winding motor 26 is arranged on one side of the moving plate 24, and a stabilizing plate 25 is inserted on the other side. The output end of the winding motor 26 is connected with a rotating tooth column 27. One end of the rotating tooth column 27 extends into the tooth hole 21 and meshes with the tooth hole 21. By starting the stepping motor 22 to control the rotation of the threaded rod 23, the moving plate 24 can drive the winding motor 26 and the rotating tooth column 27 to move away from the winding roller 2 under the limit of the stabilizing plate 25, so that the rotating tooth column 27 is separated from the tooth hole 21. At this time, due to the gravity of the rolling shutter door 3 on the limit strip 13, it is convenient to control the rolling shutter door 3 to close automatically. And when the rotating tooth column 27 is inside the tooth hole 21, by starting the winding motor 26, the winding roller 2 can be controlled to wind the rolling shutter door 3, which is convenient for winding and using.

[0033] The working principle of the present utility model: Before use, connect the connector 11 with the water pipe of the water tank, and detect whether there is a fire outside through the temperature sensor 9 and the smoke sensor 10;

[0034] When it is detected that there is a fire, control the stepping motor 22 to start, so that the rotating tooth column 27 moves out of the tooth hole 21, which can make the limit strip 13 drive the rolling shutter door 3 to move downward to achieve the closing function, and start the liquid pump 4 to spray liquid through the spray holes 8 in turn to wet and cool the surface of the rolling shutter door 3, improving the fire prevention effect of the rolling shutter door 3;

[0035] At the same time, start the electric push rod 14 to control the push plate 15 to extrude the fire extinguisher pressing plate 17, so that the gas and smoke inside the fire extinguisher cylinder 16 are ejected through the fire extinguisher nozzle 18 to extinguish the fire at the fire location, improving the fire prevention effect.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
