Among them, the electrically lifted concealed smoke baffle, as a new type of fire-fighting device, has been widely used in various buildings due to its unique functions and advantages. In recent years, the structure of the electrically lifted concealed smoke baffle has been widely used due to its convenient operability and high-efficiency smoke isolation effect. However, any design will have some deficiencies;
[0003] In the frequent lifting process of the existing electrically lifted concealed smoke baffle, its transmission mechanism, guide rails and connecting components are prone to wear, resulting in a decrease in stability.

Detailed implementation mode
[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0025] Refer to Figures 1 - 5 , the present invention provides a technical solution: an electrically lifted concealed smoke baffle, including a rolling shutter frame 1, a receiving groove 2 is arranged at the top of the rolling shutter frame 1, and a through hole 3 is arranged in the middle of the receiving groove 2. T-shaped chutes 4 are arranged on both sides inside the rolling shutter frame 1, and the T-shaped chutes 4 are connected to the inside of the through hole 3. A T-shaped slider 6 matching the T-shaped chute 4 is arranged inside the rolling shutter frame 1, and a segmented smoke baffle 7 is connected to the side of the T-shaped slider 6. A magnetic attraction block 9 matching the through hole 3 is arranged at the bottom of the segmented smoke baffle 7, and a lifting rolling shutter mechanism is arranged inside the receiving groove 2. The lifting rolling shutter mechanism is a rotating winding structure driven by dual motors for switching, and a detachable cover plate 5 is arranged on the side of the receiving groove 2, and multiple groups of reinforced gypsum boards 8 are arranged outside the cover plate 5. A connecting mechanism is arranged at the top of the receiving groove 2.
[0026] Refer to Figure 1 , Figure 2 , a mounting plate 10 is arranged outside the rolling shutter frame 1, and multiple groups of mounting holes 11 are arranged inside the mounting plate 10. A placement groove 12 is arranged inside the rolling shutter frame 1 below, and a magnetic attraction suction cup 13 matching the magnetic attraction block 9 is arranged inside the placement groove 12. The connecting mechanism includes a boss 27, a threaded hole 28, a threaded rod 29, a connecting plate 30, and a fixing hole 31. Multiple groups of bosses 27 are arranged at the top of the receiving groove 2. A threaded hole 28 is arranged inside the boss 27, and a threaded rod 29 matching the threaded hole 28 is movably connected to the outside of the boss 27. A connecting plate 30 is arranged at the top of the threaded rod 29, and multiple groups of fixing holes 31 are arranged inside the connecting plate 30 to form a connecting structure.
[0027] In specific implementation, during the installation of a concealed smoke baffle with electric lifting, first manually rotate the threaded rod 29 to connect the threaded rod 29 to the internal threaded hole 28. Then, install the connecting plate 30 on the indoor top through the fixing hole 31, so that the receiving groove 2 at the top of the rolling curtain frame 1 is installed inside the ceiling, making the installation more convenient. Next, the mounting plate 10 is fixedly installed on the side of the structure through the mounting hole 11 to hide the rolling curtain frame 1 inside the wall. Since the reinforced gypsum board 8 is fixedly installed on the outside of the receiving groove 2 and the cover plate 5, and the latex paint layer is coated on the surface of the reinforced gypsum board 8, the entire smoke baffle is hidden inside the ceiling, improving the aesthetics. Through the above operations, the indoor space is effectively saved, and the aesthetics, stability and durability of the concealed smoke baffle are improved.
[0028] Refer to Figure 3 , Figure 4 , the lifting rolling curtain mechanism includes a main driving motor 14, a standby driving motor 15, a driving gear 16, a driven gear 17, a winding shaft 18, a winding and unwinding disc 19, a baffle 20, a strip rod 21, and a card slot 22. And a winding shaft 18 is arranged inside the receiving groove 2, a winding and unwinding disc 19 is sleeved outside the winding shaft 18, and a strip rod 21 is arranged outside the winding shaft 18. A card slot 22 matching the strip rod 21 is arranged inside the winding and unwinding disc 19 and is in sliding connection. And baffles 20 are arranged on both sides of the winding and unwinding disc 19. Main driving motors 14 and standby driving motors 15 are arranged at both ends of the side surface of the winding shaft 18, and driving gears 16 are arranged at the output ends of the main driving motor 14 and the standby driving motor 15. Driven gears 17 are arranged on the side surfaces of the two ends of the outside of the winding shaft 18 and located at the side of the winding and unwinding disc 19. And an installation groove 223 is arranged inside the rolling curtain frame 1 below the main driving motor 14 and the standby driving motor 15. An electric telescopic rod 222 is arranged inside the installation groove 223, and a transfer gear 221 is arranged at the top of the electric telescopic rod 222. The driving gear 16, the driven gear 17 and the transfer gear 221 are meshed and connected to form a lifting rolling curtain structure.
[0029] Refer to Figure 5 , the side surface of the receiving groove 2 is installed with a cover plate 5 through a bolt 23, and a slideway 24 is arranged on the side surface of the cover plate 5. A protection plate 25 matching the slideway 24 is arranged inside the cover plate 5 and is in sliding clamping connection. A plurality of groups of smoke sensors 26 are arranged on both sides of the through hole 3 above the inside of the rolling curtain frame 1.
[0030] In specific implementation, when an electric-lifting concealed smoke baffle is in use, first start the main drive motor 14. The electric telescopic rod 222 extends and retracts the transfer gear 221, causing the transfer gear 221, the driving gear 16, and the driven gear 17 to be meshed and connected. The winding shaft 18 is rotated by driving with the main drive motor 14, and then the take-up and release reel 19 quickly descends the segmented smoke baffle 7, thereby enabling the T-shaped slider 6 to slide quickly inside the T-shaped chute 4. At the same time, start the magnetic suction cup 13, and the magnetic suction cup 13 adsorbs the magnetic block 9, further ensuring the speed of the segmented smoke baffle 7 during its descent and the sealing performance after the descent, guaranteeing the smoke-blocking effect. Meanwhile, the segmented smoke baffle 7 is internally made of materials such as fireproof glass and silicate board. Fireproof glass is a transparent fireproof material with excellent fireproof and heat insulation properties. In the smoke baffle, the fireproof glass can not only block smoke and flames but also improve the permeability of the field of vision. Thus, through the above operations, the safety of the concealed smoke baffle is enhanced;
[0031] When the concealed smoke baffle needs maintenance, the detachable cover plate 5 on the side of the receiving groove 2 can be used to remove the protective plate 25 by sliding the protective plate 25 and removing the bolts 23, enabling maintenance and repair inside the receiving groove 2, facilitating the internal cleaning and maintenance of the concealed smoke baffle. At the same time, for the lifting roller blind structure, the take-up and release reel 19 is sleeved outside the winding shaft 18, and the segmented smoke baffle 7 can be replaced as a whole regularly, improving safety. Thus, through the above operations, the stability and durability of the electric-lifting concealed smoke baffle are enhanced, the control and response speed are increased, and the difficulty of maintenance and repair is reduced.
[0032] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
