DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-7 A fire door with heat insulation and cooling function comprises a door panel frame 1, a cover plate 2 is installed on the door panel frame 1, a device box 3 is installed on the side of the door panel frame 1 away from the cover plate 2, a regulating component 4 is installed in the device box 3, a water connection pipe 5 is installed on the side of the door panel frame 1, the water connection pipe 5 is connected to an external water source, a pressure switch 11 is installed on the water connection pipe 5, one end of the water connection pipe 5 passes through the door panel frame 1 and is exposed to the outside of the fire door, and the other end is connected to a fire water pump 6, The fire water pump 6 is connected to a water tank 7, which is located at the bottom of the door panel frame 1. A cooling pipe 8 is installed on the door panel frame 1. The cooling pipe 8 and the water tank 7 are both filled with cooling water, and one end of the cooling pipe 8 is connected to the water tank 7, and the other end is connected to a water outlet pipe 9. The water outlet pipe 9 is located in the equipment box 3, and a number of closed sprinkler heads 10 are rotatably connected thereto, and the several closed sprinkler heads 10 are all exposed to the outside of the equipment box 3.

[0030] When the fire outside the fire door causes the temperature to rise continuously, the closed sprinkler head 10 automatically explodes after reaching its operating temperature. At this time, the water outlet pipe 9 starts to transport water to the closed sprinkler head 10, and the closed sprinkler head 10 starts to spray water on the flame to slow down the burning speed of the flame. When the water flows in the water outlet pipe 9, it will generate an electrical signal to the pressure switch 11. At this time, the pressure switch 11 starts the fire pump 6. The operation of the fire pump 6 drives the external water source to flow into the water tank 7, and the water flows into the cooling pipe 8 through the water tank 7, thereby replenishing The amount of water in the cooling pipe 8 can provide sufficient water flow for the closed sprinkler nozzle 10. The fire door can always maintain a temperature close to the cooling water by setting the water tank 7 and the cooling pipe 8, thereby counteracting the high temperature generated by the flame and reducing the temperature of the fire door when it is roasted by the flame. At the same time, the water flow in the water tank 7 and the cooling pipe 8 forms a partition layer between the door frame 1 and the cover plate 2, so that the temperature on the door frame 1 cannot be transmitted to the cover plate 2 in real time, effectively reducing the temperature on the cover plate 2 and improving the thermal insulation of the fire door.

[0031] Reference Figure 2 In this embodiment, a semiconductor refrigeration sheet 17 is installed on the side wall of the water tank 7. The cooling surface of the semiconductor refrigeration sheet 17 is attached to the water tank 7, and a heat sink 12 is installed on its heating surface. The end of the heat sink 12 away from the semiconductor refrigeration sheet 17 is attached to the cover plate 2. The cover plate 2 and the door panel frame 1 are both made of steel, so that when the semiconductor refrigeration sheet 17 is in operation, its cooling surface can transfer the low temperature to the water tank 7, and then transfer it to the cooling water in the water tank 7, thereby reducing the temperature of the water flow and improving the heat resistance of the fire door; the heat generated on the heating surface of the semiconductor refrigeration sheet 17 is transferred to the heat sink 12, and the heat sink 12 dissipates the temperature. At the same time, the heat sink 12 contacts with the cover plate 2, and the temperature on the heat sink 12 is transferred to the cover plate 2, and the cover plate 2 further dissipates the heat, thereby improving the heat dissipation efficiency of the semiconductor refrigeration sheet 17 and ensuring the stability of the temperature inside the fire door.

[0032] Reference Figure 3-4In this embodiment, a transmission water pump 13 is connected to the pipeline between the water tank 7 and the cooling pipe 8. The transmission water pump 13 is associated with the fire water pump 6. Through the setting of the transmission water pump 13, the cooling water in the water tank 7 can flow into the cooling pipe 8 to supplement the water volume in the cooling pipe 8; because the transmission water pump 13 is associated with the fire water pump 6, the fire water pump 6 can trigger the transmission water pump 13 to run synchronously when it is running, so that the water flow brought into the water tank 7 by the fire water pump 6 can flow into the cooling pipe 8, thereby realizing the circulation of water flow, so that the water volume in the water tank 7 and the cooling pipe 8 is always guaranteed to be sufficient and flowable, so that the water flow whose temperature rises after being roasted by the flame can be discharged by the closed sprinkler head 10 to control the degree of flame spread, and the water flow in the water tank 7 and the cooling pipe 8 can be in a low temperature state, so as to protect the fire door and improve the service life of the fire door.

[0033] Reference Figure 2 In this embodiment, a pearl rock wool fireproof board 14 is filled between the door panel frame 1 and the cover plate 2. A first connecting groove 15 is provided on the pearl rock wool fireproof board 14. The first connecting groove 15 is adapted to the heat sink 12. The use of the pearl rock wool fireproof board 14 can further improve the fire resistance of the fire door, increase the service life of the fire door, and buy time for the evacuation of personnel. The setting of the first connecting groove 15 enables the heat sink 12 to pass through the pearl rock wool fireproof board 14 through the first connecting groove 15 and maintain contact with the cover plate 2, thereby ensuring effective heat dissipation of the semiconductor refrigeration plate 17.

[0034] Reference Figure 3 In this embodiment, a second connecting groove 16 is provided on the door panel frame 1, and the second connecting groove 16 is adapted to the equipment box 3, so that the equipment box 3 can be connected to the door panel frame 1 through the second connecting groove 16, so that the water outlet pipe 6 can be connected to the cooling pipe 8 without obstacles, thereby ensuring that the water outlet pipe 9 can always keep in communication with the cooling water, thereby ensuring the normal operation of the closed sprinkler head 10.

[0035] Reference Figure 4-6 In this embodiment, the regulating component 4 includes an infrared sensor 405 installed on the lower wall of the device box 3. Two connecting parts 401 are installed in the device box 3. A servo motor 402 is installed on one of the connecting parts 401. The output end of the servo motor 402 is connected to a rotating shaft 403. The rotating shaft 403 is rotatably installed between the two connecting parts 401, and two connecting blocks 404 are installed on the rotating shaft 403. The ends of the two connecting blocks 404 away from the rotating shaft 403 are connected to the water outlet pipe 9.

[0036] When the fire spreads to the sensing range of the infrared sensor 405, the infrared sensor 405 stimulates the servo motor 402 to operate, and the servo motor 402 rotates counterclockwise, causing the rotating shaft 403 to rotate synchronously, resulting in the synchronous rotation of the water outlet pipe 9 connected to the rotating shaft 403 through the connecting block 404, thereby driving the closed sprinkler head 10 connected thereto by the pipeline to move in a direction away from the servo motor 402, thereby adjusting the angle of the closed sprinkler head 10, so that the closed sprinkler head 10 can spray the flame in the sensing area of ​​the infrared sensor 405, further controlling the spread of the fire, reducing property losses, and extending the evacuation time of personnel.

[0037] Reference Figure 4 In this embodiment, a plurality of third connecting grooves 406 are provided at the bottom of the equipment box 3, and the plurality of third connecting grooves 406 are adapted to the plurality of closed sprinkler heads 10, so that the plurality of closed sprinkler heads 10 can be connected to the water outlet pipe 9 via the third connecting grooves 406, thereby ensuring that the plurality of closed sprinkler heads 10 can extend from the equipment box 3 via the corresponding third connecting grooves 406, thereby ensuring that the plurality of closed sprinkler heads 10 can spray to the external area of ​​the fire door, thereby satisfying the spraying conditions for paired fires.

[0038] Reference Figure 6 In this embodiment, a telescopic tube 407 is installed on the cooling pipe 8, and one end of the telescopic tube 407 away from the cooling pipe 8 is connected to the water outlet pipe 9, so that the water outlet pipe 9 can be connected to the cooling pipe 8 through the telescopic tube 407, thereby avoiding the end of the water outlet pipe 9 connected to the cooling pipe 8 being affected by the rotational force when the water outlet pipe 9 rotates, resulting in connection failure or the rotation of the water outlet pipe 9 being affected, thereby providing protection for the connection between the water outlet pipe 9 and the cooling pipe 8 and the rotation state of the water outlet pipe 9.

[0039] Reference Figure 5 In this embodiment, a plurality of positioning blocks 408 are installed on the top wall of the equipment box 3, and the water outlet pipe 9 is rotatably installed on the plurality of positioning blocks 408, so that the water outlet pipe 9 can be installed on the equipment box 3 through the plurality of positioning blocks 408, and the plurality of positioning blocks 408 provide support force and position limitation for the water outlet pipe 9, and the water outlet pipe 9 is rotatably connected to the positioning blocks 408 to ensure that its rotation state can be carried out normally, thereby providing a guarantee for the angle adjustment of the closed sprinkler nozzle 10.

[0040] Reference Figure 7In this embodiment, a connecting shaft 409 is installed at the inner center of a plurality of closed sprinkler heads 10, and a plurality of fan blades 410 are rotatably installed at the top of the connecting shaft 409. A plurality of water spraying grooves 411 are distributed circumferentially on the plurality of closed sprinkler heads 10, and the ends of the plurality of water spraying grooves 411 away from the fan blades 410 are inclined toward the outside of the closed sprinkler head 10. When water flows into the closed sprinkler head 10 through the outlet pipe 9, the impact force of the water flow drives the plurality of fan blades 410 to rotate rapidly, thereby driving the closed sprinkler head 10 to rotate, and then the water flows out of the closed sprinkler head 10 through the plurality of water spraying grooves 411, so that the closed sprinkler head 10 rotates while driving the water flowing out of it to rotate synchronously, thereby expanding the spraying area of ​​the closed sprinkler head 10, and then cooperating with the rotation of the outlet pipe 9, the fire door can effectively cope with fire conditions of different angles, different distances and different ranges.
