Description

Technical Field

[0001] This utility model relates to the field of fireproof rolling shutter door technology, specifically to an easy-to-install fireproof rolling shutter door. Background Technology

[0002] In modern building safety protection systems, fire-resistant roller shutters are key equipment for preventing the spread of fire. Their installation stability is directly related to the effectiveness of fire safety. Underground buildings such as underground parking lots, underground shopping malls, and underground civil defense projects have a high risk of fire due to their relatively enclosed spaces. Fire-resistant roller shutters are installed between different fire compartments, between parking lots and equipment rooms, etc., to effectively prevent the spread of fire and buy time for personnel evacuation and fire rescue.

[0003] Chinese Patent No.: CN208236260U, a fireproof rolling shutter door fireproof rolling box, including a fireproof rolling box, a fireproof rolling shutter, an electric telescopic rod, a mounting groove, a roller, and an opening. A motor frame is welded to the upper inner side of the fireproof rolling box, and a drive motor is mounted on the motor frame. The drive motor is fixed to the motor frame by a fixing bracket. A side plate is bolted to one side of the fireproof rolling box, and a bushing is installed inside the side plate. The two ends of the roller are installed inside the bushings. Two limiting rings are provided on the surface of the roller near one end of the side plate. In this invention, after the fireproof rolling shutter is fully lowered, the electric telescopic rod drives a pressure plate to move towards the fireproof rolling shutter and press against the surface of the fireproof rolling shutter, thereby sealing the gaps on both sides of the opening. This avoids the problem of smoke leakage caused by gaps between the opening of the existing rolling box and the two sides of the fireproof rolling shutter.

[0004] The aforementioned patents also have some shortcomings. They mainly focus on the structural design of the fireproof rolling shutter box, and address issues such as smoke leakage, shutter deviation, and smooth lifting. However, in actual use, the environment in which the fireproof rolling shutter box is located may be more complex, with higher humidity. Moisture in the air can easily accumulate inside the box, potentially causing metal components such as the motor frame, drive motor, and bushings to become damp and rust, affecting their performance and service life. It may also cause some electronic components or control systems to malfunction due to moisture, leading to mechanical failure. Therefore, we need to propose a fireproof rolling shutter door that is easy to install. Utility Model Content

[0025] 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.

[0026] Please see Figures 1-6This utility model provides a technical solution: an easy-to-install fireproof roller shutter door, including a housing 1, a roller 2, and a roller shutter 3. The roller 2 is located inside the housing 1, and the roller shutter 3 is located inside the housing 1 and extends to the outside of the housing 1. The housing 1 serves as the main support structure of the fireproof roller shutter door, providing installation space for the roller 2, air intake components, air inflation components, etc., and protecting these components. It also serves as a storage space for the roller shutter 3. One end of the roller 2 is connected to the inner wall of one side of the housing 1, serving as support and positioning. The other end is connected to the output shaft of the motor 20. When the motor 20 is running, the output shaft drives the roller 2 to rotate. When the motor 20 rotates forward, the roller 2 winds the roller shutter 3, causing the roller shutter 3 to rise and enter the housing 1. When the motor 20 rotates in reverse, the roller 2 releases the roller shutter 3. The roller shutter 3 descends under the action of gravity and the bottom beam 22, covering the area that needs protection. The top of the roller shutter 3 is firmly connected to the roller 2, and it rises and falls under the action of the roller 2.

[0027] An air intake assembly is installed on the top of the housing 1 to reduce the air pressure by extracting air from inside the housing 1. One end of the air intake assembly extends into the interior of the housing 1. The air intake assembly includes a first exhaust pipe 4, a vacuum pump 5, and a first intake pipe 6. The vacuum pump 5 is located on the top of the housing 1. One end of the first intake pipe 6 is connected to the intake end of the vacuum pump 5, and the other end of the first intake pipe 6 extends into the interior of the housing 1. One end of the first exhaust pipe 4 is connected to the exhaust end of the vacuum pump 5. A fireproof cover 7 is installed outside the vacuum pump 5. The end of the first exhaust pipe 4 away from the exhaust end of the vacuum pump 5 extends to the outside of the fireproof cover 7. A one-way valve 8 is installed on the surface of the first exhaust pipe 4. After the vacuum pump 5 is started, it generates suction. One end of the first intake pipe 6 is connected to the intake end of the vacuum pump 5. The other end extends into the interior of the housing 1, drawing air from inside the housing 1 into the vacuum pump 5. After being compressed by the vacuum pump 5, the air is discharged through the first exhaust pipe 4. One end of the first exhaust pipe 4 is connected to the exhaust end of the vacuum pump 5, and the other end extends to the outside of the fireproof cover 7. A one-way valve 8 is installed on the surface of the first exhaust pipe 4. Its function is to prevent the discharged gas from flowing back, ensuring that the extracted air will not re-enter the interior of the housing 1, and ensuring that the air pressure inside the housing 1 continues to decrease. The fireproof cover 7 is made of fireproof material and has good heat insulation and fireproof performance. When a fire occurs and the ambient temperature rises, the fireproof cover 7 can effectively block the heat transfer to the vacuum pump 5, allowing the vacuum pump 5 to maintain normal operation for a certain period of time, thus ensuring the normal operation of the fireproof rolling shutter door.

[0028] An inflation assembly for filling the interior of the box 1 with argon gas for moisture protection is installed on one side of the exterior. One end of the inflation assembly extends into the interior of the box 1. The inflation assembly includes an argon cylinder 9 and a first gas supply pipe 10. The argon cylinder 9 is used to store argon gas. A sealing shell 11 is provided on the exterior of the argon cylinder 9. The argon cylinder 9 is installed on the exterior of the box 1 through the sealing shell 11. The sealing shell 11 is used to securely install the argon cylinder 9 on the exterior of the box 1. It is made of fire-resistant material and has good heat insulation and fire resistance performance, while also providing a certain degree of protection. The exhaust end of the argon cylinder 9 is connected to the first gas supply pipe 10. One end of the first gas supply pipe 10 is connected to the outside of the box 1 and extends into the inside of the box 1. A gas leak detector 12 is installed on the surface of the first gas supply pipe 10. When argon needs to be filled, the valve of the argon cylinder 9 is opened, and the argon flows into the inside of the box 1 through the first gas supply pipe 10. The gas leak detector 12 is installed on the surface of the first gas supply pipe 10 to monitor whether the argon is leaking in real time. Once an argon leak is detected, an alarm will be issued in time to remind maintenance personnel to carry out maintenance, so as to ensure the normal operation of the gas filling component and the stability of the argon environment inside the box 1.

[0029] A connecting assembly for mounting the housing 1 to the wall is installed at the rear of the housing 1. The connecting assembly includes a slide 13 and a slide plate 14. The slide 13 is vertically and symmetrically installed at the rear of the housing 1. The slide 13 has a semi-hollow structure. The shape of the internal space of the slide 13 is precisely adapted to the shape of the slide plate 14. The slide plate 14 can be tightly and gaplessly inserted into the semi-hollow interior of the slide 13. Several expansion bolts 23 are installed on the surface of the slide plate 14. A locking block 15 is horizontally arranged at the bottom of each slide 13. A movable plate 17 adapted to the locking block 15 is provided on the outside of the locking block 15. A fixing rod 16 is vertically inserted into the end of each locking block 15. The fixing rod 16 and the movable plate 17 are connected to each other. The slide plate 14 is fixed to the wall by expansion bolts 23 mounted on the surface. The slide groove 13 is vertically and symmetrically installed at the rear of the box 1. It has a semi-hollow structure and its internal space is precisely matched with the shape of the slide plate 14. The slide plate 14 is tightly inserted into the semi-hollow interior of the slide groove 13, so that the box 1 can be stably suspended on the slide plate 14. When the slide plate 14 is inserted into the interior of the slide groove 13, the movable plate 17 is pushed. The movable plate 17 fits against the locking block 15, thereby fixing the slide plate 14 inside the slide groove 13. When the movable plate 17 is fully fitted against the locking block 15, the fixing rod 16 is inserted into the end of the locking block 15 to fix the movable plate 17, thereby ensuring that the box 1 is installed stably.

[0030] The fireproof cover 7 is equipped with a controller 18 and a plate pressure sensor 19. The controller 18 is electrically connected to the plate pressure sensor 19. One end of the roller 2 is connected to the inner wall of one side of the box 1, and the other end of the roller 2 is connected to the output shaft of the motor 20. The plate pressure sensor 19 senses the air pressure inside the box 1 in real time and converts the air pressure value into an electrical signal, which is then transmitted to the controller 18. The controller 18 controls the operation of the suction component and the inflation component according to the preset air pressure threshold and the received pressure signal. When the air pressure inside the box 1 is detected to be higher than the set upper limit, the controller 18 starts the vacuum pump 5 to reduce the air pressure through the suction component. When the air pressure is lower than the set lower limit, the controller 18 can control the inflation component to fill in an appropriate amount of argon gas to maintain the air pressure inside the box 1 within a suitable range. At the same time, the controller 18 can also be linked with other external devices such as the fire alarm system to control the raising and lowering of the roller shutter door according to the fire alarm signal.

[0031] Motor 20 is installed on the inner wall of the other side of housing 1. The output shaft of motor 20 is connected to roller 2. After power is applied, the stator and rotor inside motor 20 generate electromagnetic induction, the rotor starts to rotate, drives the output shaft to rotate, and then drives roller 2 to rotate, realizing the rising and falling movement of roller shutter 3. The forward and reverse rotation of motor 20 is controlled by controller 18, which can accurately control the lifting speed and position of roller shutter door according to different operation commands and sensor feedback signals. The top of roller shutter 3 is firmly connected to roller 2, and the bottom of roller shutter 3 extends to the outside of housing 1. The bottom of roller shutter 3 is connected to bottom beam 22. When roller shutter 3 descends, the gravity generated by its own weight helps to overcome the rolling shutter. The friction between the roller shutter 3 and the guide rail 21, as well as the rolling resistance of the roller shutter 3 itself, enable the roller shutter 3 to descend quickly and evenly. After the roller shutter 3 is closed, the weight of the bottom beam 22 ensures that the bottom of the roller shutter 3 is in close contact with the ground, reducing gaps and effectively preventing the spread of flames, smoke and heat from the bottom. Guide rails 21 are provided on both sides of the roller shutter 3. The guide rails 21 are installed vertically on both sides of the roller shutter 3. During the lifting and lowering process, the edges of the roller shutter 3 are embedded in the guide rails 21. The shape and structure of the guide rails 21 restrict the direction of movement of the roller shutter, so that it can only move up and down along the length of the guide rails 21, thereby ensuring the stability and accuracy of the roller shutter 3 during operation and ensuring that the fireproof roller shutter door can reliably play its role in fire separation.

[0032] During the descent of the roller shutter 3, the entire fireproof roller shutter system adopts a comprehensive sealing and protection design to ensure that the argon gas inside the housing 1 will not leak. The housing 1, roller shutter 3, guide rail 21 and other connecting parts are all equipped with high-performance sealing structures. These sealing structures can maintain a good sealing state at all times during the movement of the roller shutter 3, effectively preventing the argon gas from leaking out. At the same time, the connection between the inflation component and the housing 1 has also been specially treated to further enhance the sealing performance during the storage and transportation of argon gas. This ensures that after the roller shutter 3 completes its descent, the argon gas concentration inside the housing 1 can still be maintained within a preset safe and effective range, continuously providing moisture protection for the internal components.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
