[0026] As a technical optimization of this utility model, by setting up a smoke detection component 4, the controller 42 starts the centralized fan 43 during use, which absorbs the surrounding wind and blows it towards the smoke sensor 41, enabling the smoke sensor 41 to effectively detect smoke and realize early warning of fire. In the event of a failure or untimely response of the building's overall automatic fire alarm system, this device can independently detect smoke. Through the cooperation of the smoke sensor 41, the controller 42, and the transmission lifting device 2, it can react quickly and automatically lower the fireproof roller shutter, buying more time for personnel evacuation and improving the emergency response capability of the fireproof roller shutter.

[0027] refer to Figure 2 The connecting sealing assembly 5 includes a connecting plate 51. The top of the connecting plate 51 is provided with an installation groove 52. An iron plate 53 is installed inside the installation groove 52. A fixing plate 54 is installed on the other side of the fireproof roller shutter device body 1. A strong magnetic block 55 is installed at the bottom of the fixing plate 54. Several strong magnetic blocks 55 are provided, and the several strong magnetic blocks 55 are arranged at equal distances.

[0028] As a technical optimization of this utility model, the sealing performance of the fireproof roller shutter is enhanced by setting the connecting sealing component 5. The iron plate 53 on the connecting plate 51 attracts the strong magnetic block 55 at the bottom of the fixing plate 54 of the fireproof roller shutter device body 1, so that the bottom of the fireproof roller shutter can fit tightly after it is lowered into place, reducing gaps. The multiple strong magnetic blocks 55 are set at equal distances to ensure the uniformity and stability of the fit, effectively blocking the spread of smoke and fire from the bottom and improving the fireproof separation effect of the fireproof roller shutter.

[0029] refer to Figure 3 A fixing groove 6 is provided on the outer side of the mounting plate 3. The smoke sensor 41 is installed inside the fixing groove 6. A connecting bracket 7 is installed on the outer side of the centralized fan 43. The inner side of the connecting bracket 7 is installed on the outer side of the mounting plate 3.

[0030] As a technical optimization of this utility model, by setting the fixing groove 6 and the connecting bracket 7, it is convenient to install and fix the smoke sensor 41 and the centralized fan 43. The smoke sensor 41 is installed in the fixing groove 6 on the outside of the mounting plate 3, which not only ensures the stability of its installation, but also facilitates replacement and maintenance. The connecting bracket 7 fixes the centralized fan 43 on the outside of the smoke sensor 41, ensuring that the centralized fan 43 can accurately guide the smoke to the sensor.

[0031] refer to Figure 3 The controller 42 is electrically connected to the remote controller 8 via wires. The remote controller 8 is installed on one side of the front of the mounting plate 3. An insulation box 9 is installed on one side of the front of the mounting plate 3. Both the controller 42 and the remote controller 8 are located inside the insulation box 9.

[0032] As a technical optimization of this utility model, by setting up a remote controller 8 and an insulation box 9, the remote controller 8 allows managers to monitor and operate the fireproof rolling shutter device remotely. Even when not on-site, they can understand the status of the device and control it in a timely manner. The insulation box 9 provides a stable working environment for the controller 42 and the remote controller 8, avoiding the impact of excessively high or low ambient temperatures on their performance, extending the service life of the equipment, and ensuring that the equipment can operate normally in emergency situations such as fires.

[0033] refer to Figure 2 A sealing strip 10 is installed on the inner side of the inner wall of the mounting plate 3, and a storage battery 11 is installed on the top of the mounting plate 3. The storage battery 11 is electrically connected to the controller 42, the smoke sensor 41, the central fan 43 and the remote controller 8 through wires.

[0034] As a technical optimization of this utility model, by setting a sealing strip 10 and a storage battery 11, the sealing strip 10 is installed on the inner wall of the mounting plate 3 and is in close contact with the fireproof roller shutter device body 1 to prevent smoke and fire from leaking from the side. When the external power supply fails, the storage battery 11 provides power support for the controller 42, smoke sensor 41, centralized fan 43, remote controller 8 and transmission lifting device 2, etc., to ensure that the fireproof roller shutter device can still work normally in the event of power failure and continue to play its fireproof separation role.

[0035] refer to Figure 2 An insulation box 12 is installed on the outside of the battery 11, and a protective box 13 is installed on the outside of the insulation box 12. The battery 11 is electrically connected to the transmission lifting device 2 through wires.

[0036] As a technical optimization of this utility model, by setting up an insulation box 12 and a protective box 13, the insulation box 12 reduces the impact of ambient temperature on the battery 11, ensures its stable performance, and extends its service life. The protective box 13 provides physical protection for the battery 11, preventing damage to the battery 11 from external impacts, and ensuring that the battery 11 can continuously supply power to the equipment in the complex environment of a fire scene, thus ensuring the reliable operation of the fireproof roller shutter device.

[0037] refer to Figure 3 A heat insulation ring 14 is provided on the outside of the centralized fan 43. An electric push rod 15 is installed on the front of the heat insulation ring 14. The electric push rod 15 is installed on the front of the mounting plate 3. A heat insulation column 16 is installed at the output end of the electric push rod 15.

[0038] As a technical optimization of this utility model, by setting up a heat insulation ring 14, an electric push rod 15 and a heat insulation column 16, after a fire has been detected, the controller 42 can activate the electric push rod 15, which will drive the heat insulation ring 14 to move to the outside of the centralized fan 43, reducing the impact of the external temperature on the centralized fan 43, preventing high temperature from damaging it, reducing the economic losses of the user, and allowing the centralized fan 43 and the smoke sensor 41 to be reused after the fire.

[0039] The working principle and usage process of this utility model are as follows: During use, the controller 42 simultaneously sends a start signal to the centralized fan 43. The centralized fan 43, fixed by the connecting frame 7, begins to operate, accelerating the blowing of surrounding smoke-containing air towards the smoke sensor 41. This allows the smoke sensor 41 to detect changes in smoke concentration more quickly and accurately. Once the smoke concentration reaches a preset threshold, the smoke sensor 41 immediately transmits an electrical signal to the controller 42 via a wire. Upon receiving the signal, the controller 42 quickly sends a command to the transmission lifting device 2 via a wire, activating the device. Its internal motor drives the roller to rotate, causing the curtain of the fireproof roller shutter device 1 to descend rapidly, forming a fireproof barrier to prevent the spread of fire and smoke. During the descent of the fireproof roller shutter device body 1, multiple strong magnetic blocks 55 at the bottom of the fixing plate 54 on the other side of the fireproof roller shutter device body 1 gradually approach the iron plate 53 in the mounting groove 52 on the bottom connecting plate 51 inside the mounting plate 3 as the curtain descends. When the fireproof roller shutter is in place, the strong magnetic blocks 55 and the iron plate 53 are tightly magnetically attracted. The equal distribution of multiple strong magnetic blocks 55 ensures the uniformity and stability of the fit between the two, effectively reducing bottom gaps and blocking the spread of smoke and fire from the bottom. At the same time, the sealing strip 10 installed on the inner side of the inner wall of the mounting plate 3 is in close contact with the side of the fireproof roller shutter device body 1, further preventing smoke and fire from leaking from the side, enhancing the sealing performance and fireproof separation effect of the fireproof roller shutter, achieving the effect of sealing detection, and enhancing the use effect of the fireproof roller shutter door.

[0040] In summary, this intelligent building smoke detection fireproof roller shutter device detects smoke by setting up a smoke detection component 4 in conjunction with a connecting sealing component 5, and seals the fireproof roller shutter body 1 when it is closed. This solves the problem that existing fireproof roller shutters cannot detect smoke and are difficult to provide early fire warnings. They often rely on the building's overall automatic fire alarm system for triggering, which results in the fireproof roller shutter not closing in time during a fire, causing inconvenience in use and reducing the effectiveness of the fireproof roller shutter.
