Description

TECHNICAL FIELD

[0001] The present application relates to a metal door, in particular to a water-cooled heat-insulated metal door. BACKGROUND

[0002] When a fire occurs, it is easy for people to be trapped indoors, especially when a fire occurs in a high-rise building. Once trapped in the room, people can only close all doors and windows, block the door gap with a wet towel or bed sheet, pour water to prevent smoke from entering, and wait for rescue. Some existing security doors have certain heat insulation effect, such as steel door body and frame to ensure structural stability at high temperature; the inside of the door leaf is filled with perlite, inorganic flame-retardant composite material and other efficient heat insulation layers to delay heat transfer; the surface is coated with inorganic fire-resistant paint to improve corrosion resistance and high temperature resistance. However, even with the above process, it is still impossible to ensure that the security door maintains good sealing under long-term fire roasting, especially the sealing strip between the door leaf and the door frame, which is easy to melt and vaporize at high temperature. Even if the door leaf remains locked, the overall sealing performance will be greatly compromised, and high-temperature toxic gas will enter the room, causing internal personnel to suffocate. SUMMARY

[0003] The present application provides a water-cooled heat-insulated metal door; solve the problem of insufficient fireproof performance of the existing metal door.

[0004] The above technical problems of the present application are mainly solved by the following technical scheme: a water-cooled heat-insulated metal door, comprising a door frame and a door leaf, the door leaf is filled with heat-insulating fireproof material, the side of the door leaf is provided with a sealing rubber ring, the door leaf is pre-buried with a first cooling pipeline, the first cooling pipeline is communicated with a first water inlet section, the opening of the first water inlet section is exposed to the outside or shielded, the first cooling pipeline is divided into an outer peripheral cooling pipe distributed along the circumference direction of the door leaf and a middle cooling pipe penetrating the middle part of the door leaf, a first through hole is opened on the door leaf and located on both sides of the sealing rubber ring, a plurality of first water outlets are arranged on the first cooling pipeline, part of the first water outlets are opposite to the first through hole, and the heat-insulating fireproof material can be soaked by water sprayed from the first water outlet.

[0005] The application pre-buried a first cooling pipeline in the door leaf, and is also provided with a water connecting hose, one end of the water connecting hose can be quickly connected with the first water inlet section, and the other end can be quickly connected with a water faucet. When a high-rise fire occurs and the escape passage is blocked, the trapped personnel can only close the door, take out the water connecting hose, connect the first water inlet section with the water faucet, and then open the water faucet. Tap water is continuously injected into the first cooling pipeline through the water connecting hose, and finally sprayed out from each first water outlet. The sprayed water can directly cool the door leaf, or can moisten the heat-insulating and fireproof material to prolong the heat-insulating effect and service life. Part of the water sprayed out from the first water outlet can also be sprayed into the joint between the door leaf and the door frame through the first through hole, so as to cool the door joint and maximize the sealing effect of the sealing rubber ring. At the same time, a large amount of steam generated by the water in the door leaf and the door frame after being heated will also be sprayed out through the first through hole, so as to disperse the smoke. Even if the sealing rubber ring fails, the high-speed steam can also partially isolate the smoke.

[0006] Further, a second cooling pipeline is pre-buried in the door frame, a second water inlet section is communicated on the second cooling pipeline, the opening of the second water inlet section is exposed to the outside or is shielded, the second cooling pipeline is distributed along the direction of the door frame, second through holes are formed on the door frame and correspond to the positions where the sealing rubber ring is attached, a plurality of second water outlets are arranged on the second cooling pipeline, and the second water outlets are opposite to the second through holes. Like the effect of the first cooling pipeline, by pre-buried the second cooling pipeline in the door frame, when a fire occurs, the first cooling pipeline and the second cooling pipeline can be simultaneously supplied with water through the three-way water connecting hose. The water sprayed out from the second water outlet can help to cool the door frame and the sealing rubber ring, thereby prolonging the sealing effect of the application.

[0007] Further, due to the physical property that fire tends to go upward, the temperature of the ceiling area is obviously higher than that of the floor. Because water flows downward, the excess water in the door leaf and the door frame will flow downward automatically. Therefore, the density distribution of the first water outlets and the second water outlets in the application follows the distribution rule that the density is higher at the top and lower at the bottom.

[0008] Therefore, compared with the prior art, the application has the following characteristics: 1. Tap water can be injected into the first cooling pipeline and the second cooling pipeline through the water connecting hose, and finally sprayed out from each water outlet. The sprayed water can cool the door leaf and the door frame, or can moisten the heat-insulating and fireproof material to prolong the heat-insulating effect and service life. 2. Part of the water can also be sprayed into the joint between the door leaf and the door frame through the through hole, so as to cool the door joint and maximize the sealing effect of the sealing rubber ring. 3. At the same time, a large amount of steam generated by the water in the door leaf and the door frame after being heated will also be sprayed out through the through hole, so as to disperse the smoke. Even if the sealing rubber ring fails, the high-speed steam can also partially isolate the smoke. BRIEF DESCRIPTION OF DRAWINGS

[0013] The technical solutions of the present application will be further specifically described below by examples in combination with the drawings.

[0014] In the description of the present application, it should be understood that the orientations or positional relationships indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0015] Example 1: see Figure 1 and Figure 2 A water-cooled heat-insulating metal door, comprising a door frame 100 and a door leaf 200, the door leaf is filled with a heat-insulating fireproof material 10, specifically perlite or inorganic flame-retardant composite material, the side edge of the door leaf is provided with a sealing rubber ring 20, a first cooling pipeline 30 is pre-buried in the door leaf, a first water inlet section 31 is communicated on the first cooling pipeline, the opening of the first water inlet section is exposed to the outside or shielded, the first cooling pipeline is divided into an outer peripheral cooling pipeline 32 distributed along the circumference direction of the door leaf and a middle cooling pipeline 33 penetrating through the middle part of the door leaf, a first through hole 101 is opened on the door leaf and located on both sides of the sealing rubber ring, a plurality of first water outlets 34 are arranged on the first cooling pipeline, part of the first water outlets are extended to be opposite to the first through hole, and the heat-insulating fireproof material can be soaked by the water sprayed by the first water outlets.

[0016] The first cooling pipeline is embedded in the door leaf, and a water connecting hose is also provided. One end of the water connecting hose can be quickly connected with the first water inlet section, and the other end can be quickly connected with a faucet. When a high-rise fire occurs and the escape passage is blocked, the trapped person can only close the door, take out the water connecting hose, connect the first water inlet section with the faucet, and then open the faucet. Tap water is continuously injected into the first cooling pipeline through the water connecting hose, and finally sprayed out of the first water outlets. The sprayed water can directly cool the door leaf or moisten the heat-insulating and fireproof material to extend its heat-insulating effect and service life. Part of the water sprayed out of the first water outlets can also be sprayed into the joint between the door leaf and the door frame through the first through hole, thereby cooling the door joint and delaying the sealing effect of the sealing rubber ring to the greatest extent. Meanwhile, a large amount of steam generated by the heated water in the door leaf is also sprayed out of the first through hole, which can also disperse smoke. Even if the sealing rubber ring fails, the high-speed steam can also partially isolate the smoke.

[0017] See Figure 1 and Figure 2 , the second cooling pipeline 40 is embedded in the door frame, the second cooling pipeline is communicated with the second water inlet section 41, and the opening of the second water inlet section is exposed to the outside or shielded. The second cooling pipeline is distributed along the direction of the door frame. The second through hole 201 is arranged on the door frame and located on both sides of the position corresponding to the sealing rubber ring. A plurality of second water outlets 42 are arranged on the second cooling pipeline, and the second water outlets face the second through hole. Like the first cooling pipeline, the second cooling pipeline is embedded in the door frame. Therefore, when a fire occurs, the first cooling pipeline and the second cooling pipeline can be supplied with water at the same time through the three-way water connecting hose. The water sprayed out of the second water outlets can help cool the door frame and the sealing rubber ring at the same time, thereby prolonging the sealing effect of the embodiment. It should be noted that the distribution path of the second cooling pipeline should avoid the position where the expansion screw is installed.

[0018] Due to the physical property that fire tends to go upward, the temperature of the ceiling area is obviously higher than that of the floor. In addition, due to the property that water flows downward, the excess water in the door leaf and the door frame also flows downward automatically. Therefore, the density distribution of the first water outlets and the second water outlets in the embodiment follows the distribution rule that the density is higher at the top and lower at the bottom.

[0019] Specifically, see Figure 4 , the inner bottom of the door leaf is provided with a water receiving compartment 102, and the door leaf is provided with a first cover plate 103 covering the water receiving compartment. The connector of the first water inlet section is located in the water receiving compartment. The inner bottom of the door frame is provided with a second cover plate 202, and the inner side of the second cover plate corresponds to the connector of the second water inlet section. The first cover plate and the second cover plate are used for shielding and protecting the connector of the water inlet section.

[0020] Specifically, the first cover plate and the second cover plate are fixed by a buckle structure, and are made of rubber or plastic material. The buckle structure facilitates quick opening, and the rubber or plastic material also facilitates violent disassembly.

[0021] Specifically, see Figure 3 The door leaf is internally provided with a first positioning sheet 104 for fixing the first cooling pipeline, and the first positioning sheet is welded and fixed with the door leaf. The door frame is internally provided with a second positioning sheet 203 for fixing the second cooling pipeline, and the second positioning sheet is welded and fixed with the door frame.

[0022] It will be apparent to those skilled in the art that modifications can be made to the application as specifically described without departing from the spirit and scope of the application. All such modifications are intended to be included within the scope of the claims.
