Description

Technical Field

[0001] This utility model relates to the field of fireproof rolling shutter door technology, specifically to a double-track steel fireproof rolling shutter door. Background Technology

[0002] Fire-resistant roller shutters are roller shutters that, along with their frames, can meet the requirements for fire resistance stability and integrity within a certain period of time. They consist of curtain panels, roller shafts, motors, and guide rails. Fire-resistant roller shutters are mainly used in walls that require fire separation, especially in firewalls and fire-resistant partitions where production or use necessitates large openings but fire doors cannot be installed.

[0003] A search revealed an existing patent (publication number: CN219138895U) that discloses a double-track steel fireproof roller shutter door. The roller shutter door body includes a main body and a fireproof component that uses fire-extinguishing substances to retard or extinguish fire. The fireproof component is located within the main body and includes a liquid. The main body includes two sets of vertical panels, a curtain panel, and a winding component for winding or releasing the curtain panel. This invention, by incorporating the fireproof component, enables the use of fire-extinguishing substances to retard or extinguish fire. This addresses the problem of existing fireproof roller shutter doors having poor fire resistance and limited fire-retardant time in large fires, thus improving safety. However, during a fire, a large amount of smoke may be generated at the scene. As the air temperature rises at the fire scene, the smoke spreads widely, easily causing people to inhale large amounts of smoke, thus affecting escape efficiency. Utility Model Content

[0004] This utility model proposes a double-track steel fireproof roller shutter door, which solves the problem in related technologies that smoke spreads widely as the air temperature at the fire scene rises, which can easily lead to people inhaling a lot of smoke and thus affect the efficiency of escape.

[0006] The smoke absorption assembly includes a box body fixedly connected to the outer wall of the bottom of the housing. Both ends of the box body are embedded with a plurality of smoke mouthpieces. The other end of each smoke mouthpiece is connected to a diversion smoke guide pipe. The other end of each diversion smoke guide pipe is connected to a smoke inlet pipe. The other end of the smoke inlet pipe is connected to an extraction pipe. The other end of the extraction pipe is connected to an air pump. The other end of the air pump is connected to a smoke outlet pipe. A purification box is fixedly connected to the bottom of the box body. The purification box is fixedly connected to the air pump. One end of the purification box is connected to an air outlet.

[0007] Preferably, the cooling assembly includes several electric telescopic rods fixedly connected to the outer wall of the top of the control box, and each of the output ends of the electric telescopic rods is hinged with a slider.

[0008] Preferably, the cooling component further includes slide rails slidably connected to the outer walls of several sliders, and the other ends of the several slide rails are fixedly connected to water storage pipes.

[0009] Preferably, the cooling component further includes several limiting blocks fixedly connected to the other end of the water storage pipe, the top of each of the limiting blocks being hinged to a limiting rod, and the top of each of the limiting rods being fixedly connected to the inner wall of the top of the control box.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] In this invention, a smoke extraction nozzle absorbs smoke from a fire scene, allowing the smoke to enter a diversion smoke guide pipe. The smoke is then guided into an extraction pipe via the smoke inlet pipe and into a purification chamber via the smoke outlet pipe. The purification chamber filters and purifies the smoke, removing harmful substances. The purified gas is then discharged from the fire scene through an outlet, thus diluting the smoke, reducing its concentration, and decreasing the amount of smoke inhaled by escaping individuals. Furthermore, water sprayed from nozzles cools the roller shutter door, lowering the temperature near the door and consequently reducing the air temperature, thus limiting the smoke's spread and improving escape efficiency.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] This application discloses a double-track steel fireproof roller shutter door. Please refer to [link / reference]. Figures 1-2 A double-track steel fireproof roller shutter door includes: a control box 1, with roller shutter body 2 installed on both sides of the bottom end of the control box 1. One end of the roller shutter body 2 is wound around the outside of the roller shaft 404. Guide rails 3 are symmetrically slidably connected to both ends of the two roller shutter body 2. Each guide rail 3 is fixedly connected to the bottom end of the control box 1. A drive assembly 4 is installed inside the control box 1 to drive the roller shutter body 2. A cooling assembly 6 is installed inside the drive assembly 4 to cool the roller shutter body 2. Smoke absorption assemblies 5 are installed on both sides of the bottom end of the control box 1 to absorb smoke at the fire scene. The smoke absorption assembly 5 includes a box 501 fixedly connected to the outer wall of the bottom end of the box 501. Several smoke nozzles 502 are embedded in both ends of the box 501. The other ends of the smoke nozzles 502 are connected to a diversion smoke guide pipe 5. 03. The smoke extraction nozzle 502 draws in smoke at different heights and then guides the smoke into the smoke pipe 504 through the diversion smoke guide pipe 503. The other end of several diversion smoke guide pipes 503 is connected to the smoke inlet pipe 504. The other end of the smoke inlet pipe 504 is connected to the extraction pipe 505. The other end of the extraction pipe 505 is connected to the air pump 506. The other end of the air pump 506 is connected to the smoke outlet pipe 507. The bottom of the box 501 is fixedly connected to the purification box 508. The purification box 508 is equipped with a smoke filter structure to purify the dust, impurities and other harmful substances inside the smoke, so as to prevent more harmful substances from being inhaled by the human body. The purification box 508 is fixedly connected to the air pump 506. One end of the purification box 508 is connected to the air outlet 509. The air outlet 509 discharges the filtered harmful gas, which facilitates the dilution of smoke at the fire scene.

[0025] Please see Figures 3-5The cooling component 6 includes several electric telescopic rods 601 fixedly connected to the outer wall of the top of the control box 1. Each of the electric telescopic rods 601 has a slider 602 hinged to its output end. The cooling component 6 also includes slide rails 603 slidably connected to the outer wall of the sliders 602. A water storage pipe 606 is fixedly connected to the other end of the slide rails 603. The cooling component 6 also includes several limiting blocks 605 fixedly connected to the other end of the water storage pipe 606. Limiting rods 604 limit the limiting blocks 605. 605 limits the water storage pipe 606, thereby limiting the water storage pipe 606 through the limiting rod 604. The top of several limiting blocks 605 are all hinged to the limiting rod 604, and the top of several limiting rods 604 are all fixedly connected to the inner wall of the top of the control box 1. The cooling component 6 also includes several nozzles 607 connected to the bottom end of the water storage pipe 606. The bottom end of the control box 1 has an opening to facilitate the accommodation of the nozzles 607. One end of the water storage pipe 606 is connected to a water inlet hose 608. The water inlet hose 608 is... The flexible pipe allows for easy movement along with the water storage pipe 606. The inlet hose 608 is connected to the water pipe, facilitating water entry into the inlet hose 608. When cooling is required on one side of the roller shutter door body 2, the electric telescopic rod 601 is activated. The output end of the electric telescopic rod 601 drives the slider 602 downwards, which in turn drives the slide rail 603 downwards. The slide rail 603 then drives the water storage pipe 606 downwards. Simultaneously, the other end of the water storage pipe 606 connects with the limiting block 60. 5. The fixed connection allows the water storage pipe 606 to rotate around the hinge of the limiting rod 604. The water storage pipe 606 drives the slide rail 603 to rotate, which in turn drives the hinge of the slider 602 to rotate. At the same time, to adapt to the angle of the slider 602, the slide rail 603 slides relative to the slider 602, thereby driving the nozzle 607 to adjust its angle. This causes the nozzle of the nozzle 607 to be biased towards one side of the roller shutter body 2, thus facilitating the cooling of one side of the roller shutter body 2.

[0026] Please see Figures 3-4 The drive assembly 4 includes a motor 401 fixedly connected to the inner wall of one end of the control box 1. A large gear 402 is fixedly connected to the output end of the motor 401. It also includes a roller 404 fixedly connected to the inner wall at the center of two small gears 403. Both ends of the large gear 402 are meshed with the small gears 403. Therefore, the rotation directions of the small gears 403 on both sides are the same, so that the rotation directions of the two rollers 404 are the same. The other ends of the two rollers 404 are rotatably connected to the inner wall of the control box 1.

[0027] Working principle and usage process: Start motor 401, which drives the large gear 402 to rotate. The large gear 402 then drives the small gears 403 on both sides to mesh and rotate. Simultaneously, the two small gears 403 drive the roller shaft 404 to rotate, which in turn drives the roller shutter door body 2 to extend. This causes the other end of the roller shutter door body 2 to move downwards on the guide rail 3, thus closing the roller shutter door body 2. In the event of a fire, the air pump 506 is activated, causing the smoke nozzle 502 to generate suction, allowing smoke to enter the diversion smoke guide pipe 503 through the smoke nozzle 502. Inside, the smoke enters the smoke inlet pipe 504 through the diversion smoke guide pipe 503, then enters the extraction pipe 505 through the smoke inlet pipe 504, and is then guided into the purification box 508 through the smoke outlet pipe 507 for purification. The purified gas is then discharged through the air outlet 509. At the same time, the water inlet hose 608 is connected to the water pipe. When the water pipe is opened, water enters the water inlet hose 608, and is then guided into the water storage pipe 606 through the water inlet hose 608. The water is then guided into the spray nozzle 607 through the water storage pipe 606, and finally sprayed out through the spray nozzle 607, thereby cooling the roller shutter door body 2.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
