[0002] The function of the smoke baffle is to block the wanton lateral flow of smoke or hot air below the top of the building during a fire, strengthen the smoke exhaust effect of each smoke prevention zone, and thus avoid the spread of the fire

[0003] As an innovative fire fighting equipment, the electric smoke baffle has the advantages of rapid response, flexibility, durability, reliability, and easy installation and maintenance, making it have broad application prospects in the field of fire prevention and control. Currently, it is more and more applied to building fire fighting scenarios

[0004] Currently, in many actual engineering application scenarios, especially in industrial buildings, it is found that various forms of process equipment will be arranged inside the building. For example, process chambers, shelves, etc. Some equipment is relatively high, and the top of the equipment is very close to the ceiling. If the equipment happens to be below the electric smoke baffle, it will cause the smoke baffle to be unable to fall during a fire, because the smoke baffle is of an integral type. As long as one part touches other objects during the falling process, the whole will be unable to fall. If the above situation occurs, the smoke baffle cannot fall normally during a fire, and it cannot form a barrier to the smoke, which will have a great impact on the smoke exhaust effect, and further have an adverse effect on ensuring the safety of personnel's lives and property Content of the Utility Model

[0028] Embodiment

[0029] Refer to Figures 1-4 , a cross-section adaptive electric smoke baffle disclosed in the present utility model, includes a smoke baffle outer box 1 with an open lower surface and a plurality of fireproof board units 2 arranged in the smoke baffle outer box 1. Among them, a mounting plate 3 is fixedly connected to the top surface of the smoke baffle outer box 1, and the mounting plate 3 is fixed to the upper top wall of the building by bolts, and the smoke baffle outer box 1 is located above the ceiling 000;

[0030] In this embodiment, the plurality of fireproof board units 2 are linearly distributed, and a ball guide rail 4 is arranged between the plurality of fireproof board units 2. Each fireproof board unit 2 is connected through the ball guide rail 4, and the tops of the plurality of ball guide rails 4 are fixed to the inner top wall of the smoke baffle outer box 1;

[0031] Furthermore, a control component 5 fixed to the lower surface of the mounting plate 3 is arranged on the outer side of the smoke baffle outer box 1, and the control component 5 penetrates the smoke baffle outer box 1 and is connected to the plurality of fireproof board units 2.

[0032] Furthermore, a baffle component 6 is arranged at the bottom end of the smoke baffle outer box 1.

[0033] Under normal conditions, the plurality of fireproof board units 2 are inside the smoke baffle outer box 1, and the baffle component 6 blocks the plurality of fireproof board units 2 inside the smoke baffle outer box 1 to prevent the fireproof board units 2 from accidentally falling.

[0034] In this embodiment, the control component 5 includes a first motor 7, a rotating shaft 8 horizontally extending into the interior of the smoke baffle outer box 1, and a plurality of cable wires 9 fixedly connected to the rotating shaft 8. Among them, the first motor 7 is fixed to the lower surface of the mounting plate 3 and is located at the side of the smoke baffle outer box 1. The output end of the first motor 7 is connected to the rotating shaft 8, and the other end of the rotating shaft 8 is rotatably connected to the inner side wall of the smoke baffle outer box 1 through a bearing. One ends of the plurality of cable wires 9 are fixedly connected to the rotating shaft 8, and the other ends are respectively connected to the plurality of fireproof board units 2 in one-to-one correspondence.

[0035] In this embodiment, the baffle assembly 6 includes a second motor 10, a gear 11, a rack 12, and two falling baffles 13. Among them, a compensation plate 14 is fixedly connected to the front surface of the smoke-proof hanging wall outer box 1. The second motor 10 is fixed to the front surface of the compensation plate 14, and the output end of the second motor 10 is arranged parallel to the rotating shaft 8. The output shaft of the second motor 10 is fixedly connected to the gear 11. The rack 12 is located below the gear 11 and meshes with the gear 11, and the top end of the rack 12 is on the same horizontal plane as the lower surface of the smoke-proof hanging wall outer box 1. The two falling baffles 13 are respectively fixed on both sides of the rack 12, and the two falling baffles 13 are slidably connected to the smoke-proof hanging wall outer box 1.

[0036] Specifically, two vertically arranged limiting plates 15 are fixed to both sides of the lower surface of the falling baffle 13. Limiting strips 16 are fixed to the opposite end faces of the two limiting plates 15. Sliding grooves 17 for sliding connection with the limiting strips 16 are formed in the opposite end faces of the two falling baffles 13. Under normal conditions, the falling baffles 13 block the lower surface of the smoke-proof hanging wall outer box 1 to prevent the fireproof board unit 2 from accidentally falling.

[0037] The utility model further includes a controller that is signal-connected to the fire protection system. The controller is simultaneously coupled to the first motor 7 and the second motor 10 to control their opening and closing.

[0038] Furthermore, a gypsum board 18 is fixedly connected to the lower surfaces of the plurality of fireproof board units 2.

[0039] The working principle and beneficial effects of the utility model are as follows:

[0040] When a fire occurs, the smoke sensor signal of the smoke-proof zone where the fire occurs is transmitted to the fire protection system. The fire protection system transmits the fire protection signal to the controller. The controller first controls the second motor 10 to start. The second motor 10 drives the gear 11 to rotate. The rack 12 meshing with the gear 11 moves towards the side away from the smoke-proof hanging wall outer box 1. The rack 12 drives the two falling baffles 13 to slide along the limiting strips 16 away from the smoke-proof hanging wall outer box 1, thereby opening the smoke-proof hanging wall outer box 1.

[0041] The controller then controls the first motor 7 to start. The output shaft of the first motor 7 drives the rotating shaft 8 to rotate, thereby releasing the plurality of cables 9. Under the action of gravity, the plurality of fireproof board units 2 fall below the ceiling 000 to form a smoke-proof hanging wall. If the fireproof board units 2 encounter process equipment during the falling process, they will stop falling. The other fireproof board units 2 that do not encounter process equipment continue to fall to the bottom height of the smoke storage bin. The process equipment body and the fireproof board units 2 in the smoke storage bin together form a smoke-proof separation space.

[0042] During reset, the controller first controls the output end of the first motor 7 to reverse, thereby winding up multiple cables 9. Under the action of the cables 9, multiple fireproof board units 2 are pulled into the smoke baffle outer box 1. Then, the controller controls the output end of the second motor 10 to reverse, driving the falling baffle 13 to reset, thereby sealing the lower surface of the smoke baffle outer box 1 again.

[0043] In one embodiment, the width of the fireproof board unit 2 can be adjusted in actual design. The smaller the width of the fireproof board unit 2 and the more the number of fireproof board units 2, the more adaptable it is to more fire protection scenarios.

[0044] For the application scenario where there are relatively tall process equipment below the smoke baffle, during the falling process of the smoke baffle, several fireproof board units 2 can be relied on to form an irregular cross-section effect, maximizing the protection of the fire exhaust function while being unaffected by the height of the process equipment.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present invention.
