Abstract
Description
Technical Field
[0001] This application relates to the field of roller shutter doors, and in particular to a fireproof roller shutter linkage control system. Background Technology
[0002] Fire-resistant roller shutters are movable fire-resistant partitions widely used in fire-resistant partitions of industrial and civil buildings. They effectively prevent the spread of fire and protect life and property, making them an indispensable fire protection facility in modern buildings. National building and fire protection codes have specific requirements for the wind pressure resistance, smoke resistance, operational stability, noise reduction, and fire resistance of fire-resistant roller shutters.
[0003] Existing fireproof roller shutters tend to have a delay in closing during a fire. This is mainly because existing fire detection methods are passive detection structures, which can only detect a fire after it has started. Since roller shutters require a certain amount of time to close, a significant amount of time is wasted between the onset of a fire and the closing of the roller shutter. Utility Model Content

The sealing box 13 facilitates the installation of the smoke sensor 14, which facilitates the detection of whether a fire has occurred. An air inlet is opened on the bottom outer wall of the detection box 7, and a filter box 9 is fixedly connected to the inner wall of the air inlet, facilitating the filtration of the air entering the sealing box 13.
[0034] In use, the frame 1 facilitates the installation of the two detection mechanisms 6, the detection mechanism 6 facilitates the active detection of whether a fire has occurred, the fireproof component facilitates the closing of the fireproof roller shutter at the moment a fire occurs, the controller 12 facilitates the control of the detection mechanism 6 and the fireproof component, the smoke sensor 14 in the sealed box 13 facilitates the detection of fire, and the filter box 9 facilitates the filtration of the air entering the sealed box 13.
[0035] Reference Figure 2-3The detection box 7, which monitors whether a fire has occurred, has exhaust vents on both outer walls. Each exhaust vent's inner wall is fixedly connected to an exhaust hood 10. The exhaust hoods 10 protect the detection box 7, preventing impurities from entering through the exhaust vents. Both exhaust hoods 10 are connected to a sealed box 13 via pipes. A filter box 9 is also connected to the sealed box 13 via pipes. An alarm 11 is fixedly connected to the top outer wall of the detection box 7. Air is supplied to the sealed box 13 through the filter box 9 and then discharged through the two exhaust hoods 10. The alarm 11 is designed to provide a warning in case of fire.

The inner wall of the filter box 9 is fixedly connected to the fan 16, and the inner wall of the filter box 9 is equipped with a cleaning component 15. The fan 16 is designed to accelerate the airflow in the sealed box 13, and the cleaning component 15 is designed to clean the impurities adhering to the filter cover 23. Therefore, it can effectively prevent the filter cover 23 from being blocked by impurities, thereby preventing the filter cover 23 from being blocked and affecting the air intake.
[0036] Reference Figure 4-5 The cleaning assembly 15 for assisting in cleaning the filter cover 23 includes two fixed seats 17 fixedly connected to the inner wall of the filter box 9, and a common vibrating plate 18 is rotatably connected between the two fixed seats 17. The vibrating plate 18 is rotatably installed from the midpoint, and two rubber protrusions are fixedly connected to the outer wall of the bottom of the vibrating plate 18. The fixed seats 17 facilitate the rotation and installation of the vibrating plate 18. When the vibrating plate 18 swings, it vibrates by impacting the filter cover 23 through the rubber protrusions.

The slide grooves 2 facilitate the restriction of the sliding trajectory of the roller shutter body 3. The alarm 11, drive motor 5, smoke sensor 14, fan 16 and electric telescopic rod 22 are all electrically connected to the controller 12. The controller 12 facilitates the rapid linkage of electrical components, thereby enabling the roller shutter body 3 to close quickly.
[0038] The implementation principle of the fireproof roller shutter linkage control system in this application embodiment is as follows: In use, two detection mechanisms 6 are set on both sides of the frame 1. The fan 16 in the detection box 7 starts to accelerate the air flow in the sealed box 13. When smoke in the air enters the smoke sensor 14 during a fire, the smoke sensor 14 is triggered. At this time, the smoke sensor 14 transmits the detected signal to the controller 12. The controller 12 directly controls the alarm 11 and the drive motor 5. The alarm 11 alerts the drive motor 5, which directly drives the roller shutter door body 3 to close. When the fan 16 in the detection box 7 starts, the outside air enters the sealed box 13 through the filter cover 23. When a large amount of impurities adhere to the filter cover 23, it needs to be cleaned. During cleaning, the electric telescopic rod 22 drives the rack 21 to move back and forth. When the rack 21 moves back and forth, it directly drives the gear 19 to rotate. When the gear 19 rotates, it drives the vibrating plate 18 to swing. When the vibrating plate 18 swings, it drives the rubber protrusion to impact the filter cover 23, thereby facilitating the removal of impurities adhering to the filter cover 23.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
