[0021] See also Figure 1-4The utility model provides an embodiment: a fireproof partition door device for high-rise buildings, including a fireproof door 1 and a smoke alarm 4 fixed on the side wall of the fireproof door 1 by bolts. The model of the smoke alarm 4 is XL-83, which is used to receive and send out a smoke alarm. The fireproof door 1 is made of aluminum alloy and has good fireproof performance. A notch 2 is opened at the middle position of the top and bottom of the fireproof door 1. A plurality of overflow holes 19 are opened at equal intervals near the inner bottom of the notch 2 near the smoke alarm 4. The overflow holes 19 are all inclined at forty-five degrees. , which improves the convenience of water mist circulation, facilitates water flow to infiltrate the surface of the fire door 1, and improves the fireproof performance of the surface of the fire door 1. The two side walls of the fire door 1 near the notch 1 2 are symmetrically provided with notches 2 6, and the side wall of the fire door 1 near the bottom of the smoke alarm 4 is provided with a notch 3 9. The side wall of the fire door 1 near the bottom of the notch 3 9 is provided with an installation groove 11, and the inner side wall of the installation groove 11 is provided with a pipe groove 3, which is arranged in a U shape and connected with the notch 1 2. The interior of the fire door 1 near the bottom of the installation groove 11 is provided with a filter layer 20. The top of the filter layer 20 is plugged with a connecting pipe 15 for connecting to the installation groove 11. The inner bottom end of the installation groove 11 is installed with a water pump 13. The water pump 13 and the smoke alarm 4 are connected by wires for convenient linkage. The water outlet of the water pump 13 is plugged with a pipe 14. The other end of the pipe 14 penetrates the pipe groove 3 and is plugged with a nozzle 21. The water inlet of the water pump 13 is plugged with a pipe 27. Both the pipe 14 and the pipe 27 are silicone rubber hoses. The pipe 27 penetrates the connecting pipe 15 and is plugged into the inner bottom of the pipe 27. The installation groove 11 is close to the connecting pipe 11. A connecting pipe 2 16 is inserted into the inner bottom of 5, and the connecting pipe 2 16 is connected with the filter layer 20. A plug is inserted into the top of the connecting pipe 2 16 for easy water injection. When the smoke alarm 4 senses the smoke generated by the combustion, the water pump 13 is linked to spray the water stored in the filter layer 20 from the nozzle 21 through the pipe 2 17 and the pipe 1 14 in turn. The nozzle 21 is connected to the top of the pipe groove 3 to atomize the water, and then circulates in the groove 1 2 and the groove 2 6, so that the frame of the fire door 1 is moistened to form a dense water film, thereby improving the sealing of the fire door.

[0022] A handle 1 8 and a handle 2 18 are fixedly provided on the two walls of the fire door 1 near the slot 3 9 in sequence. The outer dimensions of the handle 1 8 and the handle 2 18 are connected and symmetrically distributed. A glass window 10 is clamped in the middle position of the slot 3 9. The glass window 10 is a double-layer laminated fire-resistant glass, which is convenient for operators to observe the fire.

[0023] A sealing strip 1 5 is clamped on the side walls of the fire door 1 near the two notches 1 2, and a sealing strip 2 7 is clamped on the side walls of the fire door 1 near the two notches 2 6. The sealing strip 1 5 and the sealing strip 2 7 are both made of silicone rubber and are U-shaped. Both ends of the sealing strip 1 5 and the sealing strip 2 7 are provided with chamfers, which improves the sealing performance around the fire door 1. When the sealing strip 1 5 and the sealing strip 2 7 come into contact with the water mist sprayed by the nozzle 21, they absorb water and expand, further improving the sealing performance around the fire door 1.

[0024] Baffles 12 are symmetrically fixed on the side walls of the fire door 1 near the installation groove 11, and cover plates 22 are clamped inside the baffles 12 to close the installation groove 11. The external dimensions of the cover plates 22 are compatible with the external dimensions of the two baffles 12. Lifting the cover plates 22 can leak out of the installation groove 11 to facilitate operators to inspect the water pump 13 and replenish the water inside the filter layer 20.

[0025] Working principle: When the fireproof partition door device for high-rise buildings is in use, the operator first rotates the fireproof door 1 with a hinge and connects it to the door opening of the rescue passage of the high-rise building. The fireproof door 1 has a built-in power supply to provide power for starting the smoke alarm 4 and the water pump 13, and then fills water into the filter layer 20 from the connecting pipe 16. The filter layer 20 is rectangular and coated with waterproof paint on the surface to improve the waterproof performance of the filter layer 20. The power supply and protective water paint are both existing technologies and will not be repeated here. When the smoke alarm 4 senses the smoke produced by combustion, the water pump 13 is linked to spray the water stored in the filter layer 20 from the nozzle 21 through the pipe 2 17 and the pipe 1 14 in turn, and then circulates inside the slot 1 2 and the slot 2 6, so that the frame of the fireproof door 1 is moistened to form a dense water film, thereby improving the sealing of the fireproof door.

[0026] Secondly, the sealing strip 1 5 and the sealing strip 2 7 are made of silicone rubber, which is elastic and non-combustible. When the sealing strip 1 5 and the sealing strip 2 7 come into contact with the water mist sprayed by the nozzle 21 , they absorb water and expand, further improving the sealing performance around the fire door 1 .

[0027] Finally, the baffles 12 are all L-shaped and symmetrically distributed, which is convenient for clamping and positioning the cover plate 22. The cover plate 22 can be lifted out of the installation groove 11 to facilitate operators to repair the water pump 13 and replenish the water inside the filter layer 20.
