Description

Technical Field

[0001] The invention relates to the technical field of folding doors, in particular to a folding door with automatic cooling and fire-fighting functions. Background Art

[0002] The folding door is a barrier mechanism composed of multiple strip-shaped plates. It is opened and closed by lifting up and down. By folding the top, it can effectively save the internal space of the passage, especially the lower space.

[0003] The function of traditional folding doors is only to close passageways. When a fire occurs inside a building, they cannot automatically sense and control the fire and assist in controlling the fire, resulting in limited safety and simple functionality. At the same time, different fire extinguishing methods cannot be switched according to different fire conditions inside the building, causing a large amount of heat and toxic gases to accumulate at the passageway, seriously hindering escape and rescue. Summary of the invention

[0004] The technical problem to be solved by the present invention is that when a fire occurs inside a building, the traditional folding door cannot automatically sense and control and assist in controlling the fire, resulting in limited safety and relatively simple functionality.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a folding door with automatic cooling and fire-fighting functions, comprising a main frame, a top storage box body is fixedly installed on the top surface of the main frame, a lateral lifting guide rail extending toward the inside of the top storage box body is fixedly installed on the inner side surface of the main frame, a folding door body is movably installed inside the main frame through the lateral lifting guide rail, an electric-controlled lifting screw rod for controlling the lifting of the folding door body is installed inside the main frame, a front closing opening is opened at the upper end of the outer side surface of the main frame, an electric-controlled closing cover plate is movably installed inside the front closing opening, and a first high-pressure nozzle and a second high-pressure nozzle connected to a high-pressure water pipe are fixedly installed on the inner side surface of the electric-controlled closing cover plate.

[0006] A horizontal assembly pipe connected to the high-pressure water pipe is fixedly mounted on the inner side of the top storage box body and is located at the lower end of the inner opening of the front closed opening.

[0007] The electrically controlled closed cover comprises lateral assembly brackets movably mounted on both sides of the horizontal assembly tube, an external flip cover fixed on the lateral assembly brackets and a top adjustment support rod for controlling the lateral assembly brackets, and a temperature and smoke sensor is fixedly mounted on the inner side of the external flip cover.

[0008] The spraying direction of the first high-pressure nozzle is opposite to that of the second high-pressure nozzle, and the first high-pressure nozzle and the second high-pressure nozzle are staggeredly arranged on the inner side of the external flip cover plate.

[0009] The external flip cover plate has a first internal flow guide channel connected to the first high-pressure nozzle and a second internal flow guide channel connected to the second high-pressure nozzle. The input ports of the first internal flow guide channel and the second internal flow guide channel are respectively connected to the inside of the lateral assembly brackets on both sides.

[0010] The lateral assembly bracket comprises a curved control bracket welded and fixed to the external flip cover plate, a metal flow guide pipe fixed inside the curved control bracket, and a horizontal sleeve fixed at the input end of the metal flow guide pipe.

[0011] Internal closing plates are fixedly mounted on the inner walls of the openings on both sides of the transverse mounting tube and the inner wall of the transverse sleeve.

[0012] The inner closing plate is provided with offset flow-conducting holes.

[0013] An inner guide wheel group matched with the lateral lifting guide rail is fixedly mounted on the inner side of the folding door body, and a bottom control seat matched with the electric-controlled lifting screw rod is fixedly mounted on the bottom of the folding door body.

[0014] The folding door body is composed of a plurality of transversely placed closed cover plates, and connecting hinges are arranged on the inner side of the upper end and the outer side of the lower end of the transversely placed closed cover plates, and detachable closed cover shells are elastically mounted on the separation surfaces on both sides of the transversely placed closed cover plates.

[0015] The beneficial effects of the present invention are:

[0016] (1) The folding door with automatic cooling and fire-fighting function of the present invention has a front closing opening with an internally installed electric-controlled closing cover plate opened at the upper end of the outer side surface of the main frame. Once a fire occurs inside, the passage opening can be extinguished and cooled in the first time to form a safe escape passage, thereby greatly improving the safety of the folding door;

[0017] (2) A first high-pressure nozzle and a second high-pressure nozzle arranged in a staggered manner are fixedly mounted on the inner side of the electrically controlled closed cover plate, and the opening and closing are automatically switched by the flipping angle of the electrically controlled closed cover plate, thereby switching the fire extinguishing mode, greatly improving the fire extinguishing effect;

[0018] (3) High-temperature smoke and toxic gases are quickly drawn outwards through the Venturi effect formed by the outward spray of high-pressure water, forming a relatively wide escape passage at the bottom, greatly facilitating escape and rescue;

[0019] (4) The connection state between the horizontal assembly pipe and the first high-pressure nozzle and the second high-pressure nozzle can be automatically switched by flipping the electrically controlled closed cover plate, making the control more convenient;

[0020] (5) By adopting the timing layout design, there is no need to occupy the internal space of the folding door, which greatly improves the utilization rate of the internal space;

[0021] (6) By directly opening the existing folding door frame, modification is convenient and cost-effective;

[0022] (7) By providing a detachable closing cover at the joint of the folding door, the impact resistance and airtightness of the folding door are improved without affecting the folding and storage of the folding door. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Figure 1 , Figure 2 , Figure 3 and Figure 4 A folding door with automatic cooling and fire-fighting functions is shown, comprising a main frame 1, a top storage box 2 is fixedly mounted on the inner top surface of the main frame 1, a lateral lifting guide rail 3 extending toward the inside of the top storage box 2 is fixedly mounted on the inner side surface of the main frame 1, a folding door body 4 is movably mounted inside the main frame 1 through the lateral lifting guide rail 3, an electric-controlled lifting screw rod 5 for controlling the lifting of the folding door body 4 is mounted inside the main frame 1, a front closing opening is opened at the upper end of the outer side surface of the main frame 1, an electric-controlled closing cover plate 6 is movably mounted inside the front closing opening, and a first high-pressure nozzle 8 and a second high-pressure nozzle 9 connected to a high-pressure water pipe 7 are fixedly mounted on the inner side surface of the electric-controlled closing cover plate 6.

[0031] In order to cooperate with the connection to the external water supply pipe, a horizontal assembly pipe 10 connected to the high-pressure water pipe 7 is fixedly assembled on the inner side surface of the top storage box body 2 at the lower end of the inner opening of the front closed mouth.

[0032] In order to cooperate with installation adjustment and control, the electrically controlled closed cover 6 includes a lateral assembly bracket 61 that is movably mounted on both sides of the horizontal assembly tube 10, an external flip cover 62 fixed on the lateral assembly bracket 61, and a top adjustment support rod 63 for controlling the lateral assembly bracket 61. A temperature and smoke sensor 11 is fixedly mounted on the inner side of the external flip cover 62.

[0033] The temperature and smoke sensor 11 is composed of an internal infrared temperature sensor and a smoke concentration sensor, forming a two-stage control.

[0034] In order to facilitate switching of control modes, the spraying direction of the first high-pressure nozzle 8 is opposite to that of the second high-pressure nozzle 9 , and the first high-pressure nozzle 8 and the second high-pressure nozzle 9 are staggered on the inner side of the external flip cover 62 .

[0035] In order to cooperate with the internal flow diversion, a first internal flow guide channel 12 connected to the first high-pressure nozzle 8 and a second internal flow guide channel 13 connected to the second high-pressure nozzle 9 are opened inside the external flip cover 62, and the input ports of the first internal flow guide channel 12 and the second internal flow guide channel 13 are respectively connected to the inside of the lateral assembly bracket 61 on both sides.

[0036] In order to facilitate assembly and connection, the lateral assembly bracket 61 includes a curved control bracket 611 welded and fixed to the external flip cover 62, a metal guide tube 612 fixed inside the curved control bracket 611, and a horizontal sleeve 613 fixed at the input end of the metal guide tube 612.

[0037] The metal flow guide tube 612 on one side of the external flip cover plate 62 is connected to the interior of the first internal flow guide channel 12 , and the metal flow guide tube 612 on the other side of the external flip cover plate 62 is connected to the interior of the second internal flow guide channel 13 .

[0038] The metal flow guide pipe 612 is sleeved on the openings on both sides of the transverse assembly pipe 10 through the transverse sleeve 613 and is connected to the inside of the transverse assembly pipe 10 .

[0039] In order to cooperate with internal closure and control, internal closing plates 14 are fixedly mounted on the inner walls of the openings on both sides of the transverse assembly tube 10 and the inner wall of the transverse sleeve 613 .

[0040] In order to cooperate with the switching control, the internal closing plate 14 is provided with a staggered flow-conducting hole 15 .

[0041] In normal state, the internal closing plates on the inner walls of the openings on both sides of the horizontal assembly pipe 10 and the offset guide holes 15 on the internal closing plates on the inner walls of the horizontal sleeve 613 are offset, so that the high-pressure water inside the high-pressure water pipe 7 cannot supply liquid to the lateral assembly bracket 61;

[0042] When a fire occurs indoors, the high temperature inside triggers the temperature and smoke sensor 11, which controls the top side adjustment support rod 63 to extend and retract, thereby controlling the external flip cover plate 62 to flip outwards. At this time, the lateral assembly bracket 61 on one side of the external flip cover plate 62 rotates, and the misaligned flow guide holes inside it are connected with the misaligned flow guide holes inside the transverse assembly pipe 10. At this time, the high-pressure water pipe 7 injects high-pressure water into the first high-pressure nozzle 8 through the transverse assembly pipe 10, and the first high-pressure nozzle 8 starts to spray high-pressure water into the room to assist in fire extinguishing.

[0043] When the smoke concentration inside becomes larger and larger, the smoke concentration sensor of the temperature and smoke sensor 11 is triggered. At this time, the temperature and smoke sensor 11 controls the top side adjustment support rod 63 to continue to extend and retract, thereby controlling the external flip cover 62 to continue to flip outward. At this time, the lateral assembly bracket 61 on one side of the external flip cover 62 rotates to displace and close the offset flow guide holes inside the internal offset flow guide holes and the offset flow guide holes inside the transverse assembly tube 10, while the lateral assembly bracket 61 on the other side rotates to connect the offset flow guide holes inside the internal offset flow guide holes and the offset flow guide holes inside the transverse assembly tube 10. At this time, the high-pressure water pipe 7 injects high-pressure water into the second high-pressure nozzle 9 through the transverse assembly tube 10, and the second high-pressure nozzle 9 starts to spray high-pressure water outdoors, using the Venturi effect to form a low-pressure area on the inside, and the indoor air is quickly extracted through the adsorption effect generated by the pressure difference, and the fire is extinguished by reducing the indoor oxygen content. At the same time, by extracting smoke and high temperature from the upper side, a safe area can be quickly formed at the bottom to facilitate escape and rescue.

[0044] In order to coordinate the guidance and bottom control, an inner guide wheel set 16 cooperating with the lateral lifting guide rail 3 is fixedly mounted on the inner side of the folding door body 4, and a bottom control seat 17 cooperating with the electric control lifting screw rod 5 is fixedly mounted on the bottom of the folding door body 4.

[0045] When the electric lifting screw 5 rotates, it drives the bottom control seat 17 to rise and fall, thereby squeezing the folding door body 4 from bottom to top, and then the folding door body 4 is lifted along the lateral lifting guide rail 3 through the inner guide wheel group 16. When it is lifted to the inside of the top storage box body 2, it begins to flip from longitudinal to transverse, and is finally stored transversely inside the top storage box body 2.

[0046] In order to improve the sealing performance and compressive strength, the folding door body 4 is composed of 6 horizontal closed cover plates, and connecting hinges are provided on the inner side of the upper end and the outer side of the lower end of the horizontal closed cover plates. Removable closing cover shells 18 are elastically installed on the separation surfaces on both sides of the horizontal closed cover plates.

[0047] The separation surface of the horizontally placed closed cover plate is provided with an installation groove, and then a limit groove is provided on the inner side of the installation groove. The detachable closed cover 18 is inserted into the limit groove through the limit block at the upper end of the assembly surface and connected with the return spring in the limit groove. After the detachable closed cover 18 is installed, the limit block can be fixed by bolting the closed cover plate in the installation groove to limit the limit block and prevent it from being separated from the limit groove.

[0048] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
