DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-4 , a smoke baffle control device, including a beam-column ceiling 1, and a load-bearing track groove 3 and a flipping track seat 4 are bolted inside the beam-column ceiling 1;

[0028] Inside the load-bearing track groove 3, there are a control rotating shaft 5, a micro motor 6 and a movable magnet 7. On the flip-type track seat 4, there is a smoke baffle main body 8. The control rotating shaft 5 is rotationally connected inside the load-bearing track groove 3. The output end of the micro motor 6 is connected to the end of the control rotating shaft 5. The movable magnets 7 are equidistantly installed on the control rotating shaft 5. On the side of the smoke baffle main body 8, there is a magnetic adsorption adapter block 9. The magnetic adsorption adapter block 9 corresponds to the position of the movable magnet 7 and they are magnetically attracted to each other.

[0029] Among them, at the bottom of the beam-column ceiling 1, there is a smoke alarm 10. The smoke alarm 10 is electrically connected to the micro motor 6.

[0030] The beneficial effects expressed by this solution: By setting the movable magnets 7 on the load-bearing control rotating shaft 5 and the corresponding magnetic adsorption adapter blocks 9 on the smoke baffle main body 8, when the smoke alarm 10 detects smoke and conducts an alarm operation, the micro motor 6 is operated. The control rotating shaft 5 drives the positive and negative poles of the movable magnets 7 to flip, so that the movable magnets 7 and the magnetic adsorption adapter blocks 9 change from the magnetically attracted state to the repulsive state, pushing the magnetic adsorption adapter blocks 9 to flip downward. The overall structure is simple, and the flipping and falling operation can be carried out quickly and efficiently, enabling the device to have flip-type falling and retracting. The falling efficiency of the switch is fast, the overall structure is simple, and the ability to block smoke and hot air is excellent.

[0031] Furthermore, at the top of the side of the smoke baffle main body 8, there is a smoke guiding pipe 12. The end of the smoke guiding pipe 12 extends out of the smoke baffle main body 8.

[0032] By setting the smoke guiding pipe 12, when the smoke baffle main body 8 flips to block smoke, the smoke guiding pipe 12 can be placed in the positive direction, so that the smoke guiding pipe 12 can conduct smoke diversion and exhaust effect, and the adaptability is good.

[0033] Furthermore, inside the smoke guiding pipe 12, there is an air extraction fan 13. The air extraction fan 13 is electrically connected to the smoke alarm 10.

[0034] By setting the air extraction fan 13, the smoke guiding pipe 12 cooperates with the air extraction fan 13, and can quickly suck and divert the smoke at the bottom.

[0035] Furthermore, on the side of the smoke guiding pipe 12, there is a horizontal opening groove 14. At the top of the side of the smoke baffle main body 8, there is a support plate 11. The smoke guiding pipe 12 is located inside the support plate 11. The support plate 11 is in contact with the beam-column ceiling 1. The smoke baffle main body 8 is arranged vertically.

[0036] By setting the horizontal opening groove 14, the horizontal opening groove 14 increases the opening and diversion area, further improving the flue gas discharge efficiency. The support plate 11 plays a supporting role, so that when the smoke baffle main body 8 is magnetically adsorbed, it is supported by the support plate 11, so that the vertical placement effect can be maintained. Moreover, when the smoke baffle main body 8 flips to block the smoke, the support plate 11 plays an auxiliary role in blocking the smoke, with good adaptability.

[0037] Furthermore, the smoke baffle main body 8 is made of one of non-combustible inorganic composite plates, metal plates or fireproof glass, and an anti-collision protection pad 16 is provided on the side of the smoke baffle main body 8;

[0038] By setting that the smoke baffle main body 8 is made of one of non-combustible inorganic composite plates, metal plates or fireproof glass, the material usage range is relatively wide, and the ability to block flue gas and hot air is good. Moreover, the anti-collision protection pad 16 plays a protective role, so that when the smoke baffle main body 8 flips and falls, it is not easy to injure the user. The anti-collision protection pad 16 plays a buffer protection role, with good safety.

[0039] Furthermore, a fireproof cloth 17 and an installation clamping strip 18 are provided at the top of the smoke baffle main body 8. The fireproof cloth 17 is located inside the installation clamping strip 18, and the installation clamping strip 18 is fitted and sleeved on the top of the smoke baffle main body 8;

[0040] By setting the fireproof cloth 17 and the installation clamping strip 18, when the smoke baffle main body 8 is flipped and inverted, the flipping force can drive the installation clamping strip 18 and the fireproof cloth 17 to be thrown out, so that the fireproof cloth 17 cooperates with the installation clamping strip 18, further increasing the overall fire and smoke blocking height and further increasing the fire and smoke blocking safety.

[0041] Furthermore, the end of the control rotating shaft 5 far from the micro motor 6 extends out of the bearing track groove 3, and an electromagnetic guiding mark 15 is provided at the end of the control rotating shaft 5. The electromagnetic guiding mark 15 is matched with the position of the movable magnet 7;

[0042] By setting the electromagnetic guiding mark 15, the flipping change situation of the movable magnet 7 can be visually observed, with good adaptability and convenient control.

[0043] Furthermore, the installation clamping strip 18 is a rubber clamping strip. The upper and lower ends of the fireproof cloth 17 are respectively connected to the installation clamping strip 18 and the smoke baffle main body 8, and a center of gravity stabilizing block 2 is provided at the top of the installation clamping strip 18;

[0044] By setting the installation card strip 18 as a rubber card strip, it can be fitted and installed on the top of the smoke baffle main body 8. The upper and lower ends of the fireproof cloth 17 are respectively connected to the installation card strip 18 and the smoke baffle main body 8. Thus, when the smoke baffle main body 8 is flipped upside down, the flipping force can drive the installation card strip 18 and the fireproof cloth 17 to be thrown out. The fireproof cloth 17 plays a better role in extending the shielding height. The center of gravity stabilizing block 2 plays a role in balancing the center of gravity and adding weight. When the smoke baffle main body 8 is flipped, the center of gravity stabilizing block 2 can assist in the throwing movement, preventing the installation card strip 18 from being stuck and blocked at the smoke baffle main body 8. The detachment is relatively convenient and stable, and the practicability is good.

[0045] It should be noted that the devices in this application are all common devices in the market, which can be selected according to needs during specific use. And the circuit connection relationships of the devices all belong to simple series and parallel connection circuits. There is no innovation point in the circuit connection. Those skilled in the art can relatively easily achieve it, which belongs to the prior art and will not be elaborated here.

[0046] Working principle: By bolt - connecting and installing a bearing track groove 3 and a flip - type track seat 4 at the bottom of the beam - column ceiling 1, the bearing track groove 3 and the flip - type track seat 4 correspond to each other. The bearing track groove 3 can carry a control rotating shaft 5, a micro - motor 6, and a movable magnet 7, and the flip - type track seat 4 can carry the smoke baffle main body 8;

[0047] A movable magnet 7 is provided on the bearing control rotating shaft 5, and the smoke baffle main body 8 is provided with a corresponding magnetic - attraction adaptation block 9. When the smoke alarm 10 detects smoke and conducts an alarm operation, the micro - motor 6 can be simultaneously operated to drive the control rotating shaft 5 to rotate 180 degrees, so that the positive and negative poles of the movable magnet 7 are flipped magnetically. Thus, the movable magnet 7 and the magnetic - attraction adaptation block 9 change from a magnetic - attraction state to a repulsive state, and then push the magnetic - attraction adaptation block 9 to flip downward. The overall structure is simple, and the flipping and falling operation can be carried out quickly and efficiently, avoiding the situation that the smoke baffle cannot block well due to the rapid spread of smoke during a fire;

[0048] A smoke guiding pipe 12 is inverted on the side of the smoke baffle main body 8, and an air - extraction type fan 13 is provided inside it. And a horizontal opening groove 14 is opened on the smoke guiding pipe 12. When the smoke baffle main body 8 is flipped to block smoke, the smoke guiding pipe 12 cooperates with the air - extraction type fan 13 to quickly suck and divert the smoke at the bottom. The horizontal opening groove 14 increases the opening diversion area and further improves the smoke discharge efficiency;

[0049] The top of the smoke baffle main body 8 is provided with a fireproof cloth 17 and an installation strip 18. When the smoke baffle main body 8 is turned upside down, the turning force can drive the installation strip 18 and the fireproof cloth 17 to be thrown out, so that the fireproof cloth 17 cooperates with the installation strip 18, further increasing the overall fire and smoke blocking height, further enhancing the fire and smoke blocking safety, enabling the device to have a flipping type of falling and retracting, with a fast falling efficiency of the switch, a simple overall structure, excellent smoke and hot gas blocking ability, and solving the problems of insufficient lifting control ability of the existing vertical lifting type smoke baffle, which may cause rapid diffusion of smoke due to too slow lifting speed and insufficient safety protection ability.
