[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a hollow energy-saving metal fire door, including a door frame 1, a fire door panel 2 inside the door frame 1, a cooling device 4 fixedly connected to the upper end of the door frame 1, a fireproof handle 3 fixedly connected to the outer surface of the fire door panel 2, a sealing component 5 between the fire door panel 2 and the door frame 1, a smoke sensor 6 fixedly connected to the upper end of the door frame 1, and a controller 8 fixedly connected to the upper end of the door frame 1. By setting the cooling device 4, the metal fire door can be cooled when the fire is large, making it easier for trapped personnel to open the fire door, while also controlling the fire, protecting personnel safety, and increasing rescue time.

[0025] The cooling device 4 includes a water tank 401. Connecting pipes 402 are symmetrically fixedly connected to the lower end of the water tank 401. Booster pumps 403 are fixedly connected to the outer surfaces of the two connecting pipes 402 to pressurize the water inside the water tank 401 and introduce it into the connecting pipes 402. A diversion pipe 404 is fixedly connected to the lower end of the connecting pipe 402. Multiple nozzles 405 are fixedly connected to the lower end of the diversion pipe 404. A water inlet pipe 406 is fixedly connected to the side wall of the water tank 401. A solenoid valve 407 is provided on the outer surface of the water inlet pipe 406.

[0026] The sealing assembly 5 includes a sliding groove 503, which is formed inside the fireproof door panel 2. A spring 505 is fixedly connected to one end of the sliding groove 503, and a telescopic rod 504 is fixedly connected to the other end of the sliding groove 503. A connecting plate 502 is fixedly connected to the other end of the spring 505, and a sealing strip 501 is fixedly connected to the other end of the connecting plate 502. A groove 101 is formed inside the door frame 1. The door frame 1 and the fireproof door panel 2 are movably connected by a hinge 7. The sealing strip 501 is set inside the groove 101. By setting the sealing assembly 5, smoke can be prevented from entering from the connection between the fireproof door panel 2 and the door frame 1 when a fire occurs, preventing injury to personnel and further improving safety.

[0027] The fireproof door panel 2 has a heat insulation layer 201 symmetrically arranged inside, a fireproof layer 202 symmetrically arranged inside, and a support layer 203 arranged inside, which makes the structure of the fireproof door panel 2 more robust and improves the fireproof effect of the fireproof door panel 2.

[0028] Smoke sensor 6 is connected to controller 8, and controller 8 is connected to booster pump 403 and solenoid valve 407. When a fire occurs, smoke sensor 6 receives a signal and can transmit it to controller 8. Controller 8 can control booster pump 403 and solenoid valve 407 to open and close.

[0029] Working principle: When a fire occurs, the smoke sensor 6 receives a signal and transmits it to the controller 8. The controller 8 then controls the booster pump 403 and the solenoid valve 407 to open. Water enters the water tank 401 through the inlet pipe 406, and then enters the diversion pipe 404 through the booster pump 403 via the connecting pipe 402. The water is then sprayed onto the inner and outer sides of the fireproof door panel 2 through the nozzle 405 to cool the fireproof door panel 2 and also to block the fire. When the fireproof door is closed, the door frame 1 squeezes the sealing strip 501, and the sealing strip 501 squeezes the connecting plate 502, which in turn squeezes the telescopic rod 504 and the spring 505. Under the thrust of the spring 505, the sealing strip 501 is pushed into the groove 101 to isolate the external smoke.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
