Description

Technical Field

[0001] This utility model relates to the field of fire door technology, specifically to a fire door with a fire-resistant structure. Background Technology

[0002] Fire-resistant fire doors are building fire protection systems specifically designed to prevent the spread of fire and smoke. They are typically installed in critical locations such as fire compartments, stairwells, and corridors within buildings. Their core function is to effectively isolate the fire source and high-temperature smoke for a certain period of time during a fire, through their fire-resistant structure and sealing performance, thus buying valuable time for evacuation and fire rescue.

[0003] In existing technologies, fire-resistant fire doors mainly rely on physical barriers and fire-resistant materials to achieve fire-resistant functions, and do not have the function of active fire extinguishing. When exposed to high-temperature environments for a long time, such as continuous burning on the other side of the door, the fire door may deform or fail to seal due to heat conduction, increasing the risk of breaching the fire compartment. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a fire door with a fire-resistant structure, thereby solving the problems mentioned in the background art, such as the fire-resistant fire door lacking active fire extinguishing function, and the potential for deformation or sealing failure due to heat conduction when exposed to high-temperature environments for extended periods, thus increasing the risk of breaching fire-resistant partitions.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A fire door with a fire-resistant structure includes:

[0007] The wall, wherein a fire door frame is provided inside the wall, is characterized in that it further includes:

[0008] The door structure is located inside the fire door frame;

[0009] The spray structure is arranged on the door structure and is used to spray water towards one side of the door structure to prevent fire.

[0010] The spraying structure includes a pipeline assembly for delivering water into the door structure for cooling and a nozzle assembly for spraying water.

[0011] A support structure, arranged on the piping assembly, is used to support the piping assembly.

[0012] Preferably, the door structure includes:

[0013] Mounting framework;

[0014] Hinges are installed on the mounting frame and fire door frame;

[0015] Both flame-retardant panels are located inside the hinge.

[0016] Preferably, the piping assembly includes:

[0017] The wall-embedded pipes and transition pipes are respectively arranged inside the wall and the fire-retardant board;

[0018] Two corrugated pipes are respectively rotatably installed on the wall-embedded pipe and the transition pipe;

[0019] Two connecting rigid pipes are respectively arranged on two corrugated pipes;

[0020] Corrugated pipe two is arranged between the two connecting rigid pipes;

[0021] Hollow insulation panels are arranged between two flame-retardant panels and located within the mounting frame. The hollow insulation panels are arranged at one end of the transfer pipe and connected to the transfer pipe.

[0022] The suction pump is located at one end of the pipe embedded in the wall.

[0023] Preferably, the piping assembly further includes several guide plates, which are arranged alternately inside the hollow insulation plate.

[0024] Preferably, the nozzle assembly includes:

[0025] Several connecting pipes are arranged inside the hollow insulation board and the corresponding flame-retardant board, and the connecting pipes are connected to the hollow insulation board.

[0026] Several nozzles are arranged on corresponding connecting pipes.

[0027] Preferably, the support structure includes:

[0028] Two mounting sleeves are respectively rotatably fitted onto the wall-embedded pipe and the transition pipe;

[0029] Two support frames are rotatably mounted on two mounting sleeves, respectively;

[0030] The connecting rod is rotatably mounted on two support frames.

[0031] Preferably, the support structure further includes an installation limiting component, which is arranged on the installation sleeve and used to install the installation sleeve on the wall-mounted pipe or the transition pipe.

[0032] Preferably, the installation limiting component includes:

[0033] Two fixing rings are respectively fixedly fitted onto the wall-embedded pipe and the adapter pipe;

[0034] Several limiting screws are evenly threaded and installed inside the two mounting sleeves, with the limiting screws located below the corresponding retaining rings.

[0035] The beneficial effects of this utility model are as follows:

[0036] This invention allows water to be pumped into a hollow insulation panel by activating a suction pump, and then sprayed onto the door through a nozzle to extinguish the fire and prevent its spread. Furthermore, the water is guided by a baffle plate to promote water flow within the hollow insulation panel, which reduces the panel's heat to some extent, thus providing insulation. The water-filled hollow insulation panel, combined with the mounting frame, further enhances the flame-retardant effect.

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] Example 1:

[0050] like Figures 1 to 7 As shown, this utility model provides a fire door with a fire-resistant structure, including: a wall 1, a fire door frame 101 provided inside the wall 1, and a door structure arranged inside the fire door frame 101.

[0051] The door structure includes an installation frame 2 and hinges 201 arranged on the installation frame 2 and the fire door frame 101. Two flame-retardant plates 202 are arranged inside the hinges 201. When the installation frame 2 is pushed, it can rotate within the fire door frame 101 through the hinges 201. When the installation frame 2 is rotated, it can also rotate the flame-retardant plates 202, thereby opening the passage. The flame-retardant plates 202 can be made of perlite board to prevent the spread of fire.

[0052] Example 2:

[0053] Based on Example 1, in order to extinguish the flames in front of the door and prevent fire, a spraying structure for spraying water towards one side of the door structure is arranged on the door structure. The spraying structure includes a pipeline assembly for delivering water into the door structure for cooling and a nozzle assembly for spraying water.

[0054] The piping assembly includes a wall-embedded pipe 3 and a transition pipe 301 respectively arranged inside the wall 1 and the flame-retardant plate 202; two corrugated pipes 302 rotatably installed on the wall-embedded pipe 3 and the transition pipe 301 respectively; two connecting rigid pipes 303 respectively arranged on the two corrugated pipes 302; a corrugated pipe 304 arranged between the two connecting rigid pipes 303; a hollow heat insulation plate 305 arranged between the two flame-retardant plates 202 and located in the mounting frame 2; the hollow heat insulation plate 305 is arranged at one end of the transition pipe 301 and connected to the transition pipe 301; and a suction pump 307 arranged at one end of the wall-embedded pipe 3. By turning on the suction pump 307, water can be pumped into the wall-embedded pipe 3, and then transported to the transition pipe 301 through the corrugated pipes 302, the connecting rigid pipes 303 and the corrugated pipe 304. Subsequently, the water will enter the hollow heat insulation plate 305.

[0055] The piping assembly also includes several guide plates 306 arranged in a staggered manner inside the hollow insulation plate 305. Under the guidance of the guide plates 306, water can be promoted to flow inside the hollow insulation plate 305. While the water is flowing inside the hollow insulation plate 305, it can reduce the heat between the hollow insulation plate 305 and the flame retardant plate 202 to a certain extent.

[0056] The nozzle assembly includes several connecting pipes 308 arranged inside the hollow heat insulation plate 305 and the corresponding flame retardant plate 202. The connecting pipes 308 are connected to the hollow heat insulation plate 305. Several nozzles 309 are arranged on the corresponding connecting pipes 308. Water inside the hollow heat insulation plate 305 flows into the corresponding connecting pipes 308 and is then sprayed forward through the nozzles 309 to extinguish the flames.

[0057] Example 3:

[0058] Based on Embodiment 2, in order to avoid squeezing and blocking the pipeline assembly during the process of switching the frame 2 and the flame-retardant plate 202, a support structure for supporting the pipeline assembly is arranged on the pipeline assembly.

[0059] The support structure includes two mounting sleeves 4 that are rotatably fitted onto the wall-embedded pipe 3 and the adapter pipe 301, two support frames 401 that are rotatably installed on the two mounting sleeves 4, and a connecting rod 402 that is rotatably installed on the two support frames 401. When the flame-retardant plate 202 flips, it will cause the adapter pipe 301 to move closer to the wall-embedded pipe 3, thereby making the distance between the two mounting sleeves 4 closer. The mounting sleeves 4 can drive the corresponding support frames 401 and connecting rods 402 to flip. The flipping of the support frames 401 will drive the connecting rigid pipe 303 to move, so that the connecting rigid pipe 303 will drive the corrugated pipe 1 302 and corrugated pipe 2 304 to bend to adapt to the positional changes of the wall-embedded pipe 3 and the adapter pipe 301.

[0060] The support structure also includes an installation limiting component arranged on the mounting sleeve 4 for installing the mounting sleeve 4 on the wall-mounted pipe 3 or the transition pipe 301.

[0061] Specifically, the installation limiting assembly includes two fixing rings 403 respectively fixedly sleeved on the wall-embedded pipe 3 and the adapter pipe 301, and several limiting screws 404 evenly threaded inside the two mounting sleeves 4. The limiting screws 404 are located below the corresponding fixing rings 403. Rotating the corresponding limiting screws 404 can make them move by engaging with the threads of the mounting sleeves 4, so that the limiting screws 404 can be released from the obstruction of the fixing rings 403. At this time, pulling the mounting sleeves 4 can remove them from the corresponding fixing rings 403.

[0062] Working principle:

[0063] The wall-embedded pipe 3 can be embedded in the wall. One end of it is connected to a suction pump 307 for pumping water. By turning on the suction pump 307, water can be pumped into the wall-embedded pipe 3, and then transported through corrugated pipe 1 302, connecting rigid pipe 303 and corrugated pipe 2 304 to the transfer pipe 301. Subsequently, the water enters the hollow insulation board 305. Under the guidance of the guide plate 306, the water can be promoted to flow within the hollow insulation board 305. Afterward, the water flows into the corresponding connecting pipe 308, and then is sprayed forward through the nozzle 309. When a fire occurs near the door, active fire suppression systems can extinguish the fire source immediately. Meanwhile, the water flowing within the hollow insulation panel 305 can reduce the heat between the hollow insulation panel 305 and the flame-retardant panel 202 to a certain extent, providing insulation. Pushing the mounting frame 2 allows it to rotate within the fire door frame 101 via the hinge 201. As the mounting frame 2 rotates, it also causes the flame-retardant panel 202 and the hollow insulation panel 305 to rotate, thus opening the passageway. The rotation of the flame-retardant panel 202 will... The movable adapter pipe 301 moves, causing one of the mounting sleeves 4 to move and rotate. This causes the other mounting sleeve 4 to rotate on the wall-embedded pipe 3 via the first corrugated pipe 302, the connecting rigid pipe 303, and the second corrugated pipe 304. As both mounting sleeves 4 rotate, they rotate on the two fixing rings 403 respectively, simultaneously causing the corresponding first corrugated pipe 302 to rotate. The limiting screw 404 and the fixing rings 403 prevent the mounting sleeves 4 from... If the wall-mounted pipe 3 or the adapter pipe 301 becomes loose, the continuous movement of the adapter pipe 301 will cause the distance between the two mounting sleeves 4 to become closer. This will allow the mounting sleeves 4 to drive the corresponding support frame 401 and connecting rod 402 to rotate. The rotation of the support frame 401 will drive the connecting rigid pipe 303 to move, causing the connecting rigid pipe 303 to drive the corrugated pipe 1 302 and corrugated pipe 2 304 to bend, so as to adapt to the positional changes of the wall-mounted pipe 3 and the adapter pipe 301, and avoid the pipeline being squeezed when the switch mounting frame 2 is switched.

[0064] During use, the bellows 302, connecting rigid pipe 303, and bellows 304 can be inspected periodically. If damage occurs, the corresponding limiting screw 404 can be rotated. When the limiting screw 404 rotates, it can move through the threaded engagement with the mounting sleeve 4, allowing the limiting screw 404 to disengage from the obstruction under the fixing ring 403. At this time, the connection restriction of the mounting sleeve 4 can be released, and it can be pulled off the corresponding fixing ring 403 by pulling the mounting sleeve 4. At the same time, the bellows 302, connecting rigid pipe 303, and bellows 304 can be disassembled for replacement.

[0065] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
