Description

Technical Field

[0001] This invention provides a fireproof rolling shutter door structure, belonging to the technical field of fireproof rolling shutter equipment, and particularly relates to an inorganic fabric fireproof rolling shutter door structure and its usage method. Background Technology

[0002] Fire-resistant roller shutters, as a type of movable fire-resistant partition, refer to roller shutters that, along with their frames, can meet the requirements for fire resistance stability and integrity for a certain period of time. They are primarily made of inorganic fiber composite materials or steel, possessing excellent fire resistance and heat insulation properties. This type of facility is widely used in industrial and civil buildings, especially in fire-resistant partition areas requiring large openings, such as large supermarkets, shopping malls, specialized material markets, exhibition halls, and factory warehouses. Its main purpose is that, in the event of a fire, the fire-resistant roller shutter can automatically lower under the control of the fire central control system, effectively preventing the fire from spreading to other areas, thus buying valuable time for firefighting. It is an indispensable fire protection facility in modern buildings.

[0003] Based on the above, we can expand on the shortcomings of existing fireproof roller shutters as follows:

[0004] While existing fire-resistant roller shutters play a crucial role in building fire safety, they still have several shortcomings. First, their heat insulation and fireproofing performance is inadequate; they struggle to maintain effective fire and heat insulation for extended periods in high-temperature fire environments, potentially leading to structural instability and affecting their fire resistance. Second, their cooling capacity is insufficient; they lack effective cooling mechanisms and cannot maintain optimal performance under sustained high temperatures. Third, most fire-resistant roller shutters are functionally limited, only capable of basic opening and closing, lacking intelligent control and real-time monitoring capabilities. Faced with complex and ever-changing fire situations, these shutters lack flexible response plans and cannot automatically adjust their operating modes according to changes in fire intensity. Furthermore, the sealing performance of existing fire-resistant roller shutters is often inadequate, easily deforming or cracking under high temperatures, leading to smoke penetration. Finally, most fire-resistant roller shutters lack effective connection and communication capabilities with external fire protection systems, hindering remote monitoring and intelligent management. These shortcomings limit the effectiveness and reliability of fire-resistant roller shutters in complex fire situations, necessitating urgent improvement and innovation. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this application provides an inorganic fabric fireproof roller shutter door structure and its usage method, solving the problems of poor heat insulation and fireproof performance, limited functionality, and limited fire response capabilities of existing fireproof roller shutters. This system integrates high-efficiency heat insulation materials, an intelligent control unit, real-time monitoring sensors, and an automatic fire extinguishing device, enabling it to automatically adjust its operating mode according to changes in the fire situation, thereby improving fire prevention effectiveness and emergency response capabilities.

[0045] like Figure 1 ,2 As shown in Figures 3 and 4, an improved inorganic fabric fireproof roller shutter door structure includes a wall 1. The structure is characterized by: a roller shutter body 2, corresponding to itself, being provided between the wall 1 sections; the roller shutter body 2 being one or more combinations of fiberglass cloth, ceramic fiber cloth, or carbon fiber cloth; guide rails 3, distributed internally within the wall 1, being provided at both ends of the roller shutter body 2; a cooling system 4, located inside the wall 1 and roller shutter body 2, being provided on one side of the guide rails 3; a sealing system 5, corresponding to the roller shutter body 2, being provided inside the guide rails 3; a roller mechanism 6, corresponding to itself and located internally within the wall 1, being provided above the roller shutter body 1; a driving device 61 connected to one side of the roller mechanism 6; a control system 7, located on the outer surface of the wall 1, being provided on one side of the driving device 61; heat insulation layers 31, symmetrically distributed on both sides of the roller shutter body 2, being provided inside the guide rails 3; and the sealing structure 5 including an elastic sealing strip 51 and an intumescent fireproof material 52. The elastic sealing strip 51 is installed on the roller shutter body 2 near the guide rails 3. At both ends of the track 3, the intumescent fireproof material 52 is placed between the heat insulation layers 31. The cooling system 4 includes a cooling pipe 41 placed inside the roller shutter body 2. A coolant storage device 42 connected to itself and placed inside the wall 1 is provided on one side of the cooling pipe 41. A circulation pump 43 connected to itself is provided on the other side of the coolant storage device 42. The coolant is either a water-based coolant or a nanofluid. Several uniformly distributed heat-resistant metal sheets 21 are embedded on the surface of the roller shutter body 2. A reflective coating 22 is coated on the outer surface of the heat-resistant metal sheets 21. A temperature sensor 23 connected to the control system 7 is connected to one end of the heat-resistant metal sheet 21 near the control system 7. The control system 7 includes a detector 71 electrically connected to the temperature sensor 23. A wireless communication module 72 is provided above the detector 71. A central processing unit 73 electrically connected to the detector 71, the wireless communication module 72, the drive device 61, and the circulation pump 43 is provided on one side of the detector 71.

[0046] In this implementation plan, by setting up an inorganic fabric fireproof roller shutter door structure, the problems of existing fireproof roller shutter doors being unable to effectively prevent fire and insulate heat, having unstable structures, and insufficient cooling in high-temperature fire environments are solved. By setting the roller shutter body 2 and symmetrically distributed guide rails 3 inside the wall, the stability of the roller shutter door is ensured. The design of the cooling system 4 and sealing system 5 effectively improves the fire resistance performance. The combination of the roller mechanism 6 and the drive device 61 makes the operation of the roller shutter door more convenient.

[0047] It should be noted that the roller shutter body 2 uses fiberglass cloth, ceramic fiber cloth, or carbon fiber cloth as materials, which have good fire resistance and strength, can maintain structural stability in high-temperature environments, and effectively block the spread of flames and heat; the guide rails 3 and the heat insulation layer 31 are symmetrically distributed to ensure smooth operation of the roller shutter door, while the internal heat insulation layer further enhances the overall heat insulation performance and reduces heat conduction; the sealing system 5 includes an elastic sealing strip 51 and an intumescent fireproof material 52, which can maintain a good seal under normal conditions, and expand under high temperatures during a fire to further seal gaps and prevent flames and smoke from penetrating; the cooling system 4 is a closed-loop system consisting of a built-in cooling pipe 41, a coolant storage device 42, and a circulating pump 43, which can continuously cool the roller shutter door and extend its service life in high-temperature environments. The use of water-based coolant or nanofluid improves cooling efficiency; the uniformly distributed heat-resistant metal sheets 21 and reflective coating 22 enhance the structural strength of the roller shutter door, while the reflective coating reflects some heat radiation, further improving fire resistance; the temperature sensor 23 monitors the roller shutter door temperature in real time, providing accurate temperature data to the control system for timely adjustment of the cooling system's operating status; the control system 7 includes a detector 71, a wireless communication module 72, and a central processing unit 73, realizing intelligent control of the entire system. It can automatically adjust the cooling system according to temperature changes, control the opening and closing of the roller shutter door, and maintain real-time communication with the fire control center via wireless communication; the drive device 61 and the roller mechanism 6 ensure that the roller shutter door can open and close quickly and smoothly, responding rapidly in the event of a fire and effectively preventing the spread of fire.
