[0002] As is well known, during a fire, the most casualties are caused by the smoke generated by the fire. The hot smoke will burn people's throats and lungs, affecting the escape of people in the fire. Therefore, in fire-fighting facilities, a smoke-proof curtain that specifically plays a role in blocking smoke needs to be set up.

[0003] In the prior art, a Chinese patent with the publication number of CN206844368U was proposed to solve the above-mentioned existing technical problems. The technical solution disclosed in the patent document is as follows: The utility model discloses a smoke-proof curtain, which is characterized in that: it includes a fire-proof steel profile and a fire-proof board. The fire-proof steel profile includes a U-shaped member. The U-shaped member includes two side walls and a U-shaped bottom edge. One end of the fire-proof board is arranged inside the two side walls of the U-shaped member and is connected to the two side walls of the U-shaped member through bolts.

[0004] Although this smoke-proof curtain can block the spread of fire and smoke, when a fire occurs, it is necessary to manually operate the lowering of the smoke-proof curtain, which may delay the response time of the smoke-proof curtain and affect its fire-proof effect. Secondly, there is a risk of human error in manual operation, resulting in the problem that the smoke-proof curtain cannot be opened in time when a fire occurs. Summary of the Utility Model

Specific embodiments

[0035] The following further describes the present utility model in detail with reference to embodiments:

[0036] Embodiment 1

[0037] As Figures 1-9 shown, the present utility model provides a fireproof smoke baffle, including a protective shell 1 and a fixing plate 8. A wiring groove 17 is provided on the inner wall of the protective shell 1, and a plate groove 19 is provided at the bottom of the protective shell 1.

[0038] A cover plate 2 is snap-connected to the inner wall of the protective shell 1. A ventilation slot 3 is provided on the back of the protective shell 1, and a ventilation pipe 4 is fixedly connected to the outer wall of the ventilation slot 3, which is used to discharge the smoke sucked into the shell body, can increase air circulation, reduce temperature, and improve fireproof performance. The wiring groove 17 is used to connect the circuit.

[0039] A first mounting bracket 5 is fixedly connected to the inner wall of the protective shell 1. The front of the first mounting bracket 5 is fixedly connected to an outer shell 6. The inner wall of the outer shell 6 is fixedly connected to the outer wall of the fixing plate 8. The first mounting bracket 5 is used to fix the outer shell 6, so that the fan 10 can suck the smoke and discharge it through the ventilation pipe 4, reduce the thick smoke in the room, and increase the escape time for personnel.

[0040] A first permanent magnet synchronous motor 7 is fixedly connected to the back of the fixing plate 8. A rotating rod 9 is rotatably connected to the center of the first permanent magnet synchronous motor 7. The other end of the rotating rod 9 is fixedly connected to a fan 10. The first permanent magnet synchronous motor 7 drives the rotating rod 9 to rotate, so that the fan 10 can suck the smoke in the room into the protective shell 1, keep the air in the room circulating, and reduce the indoor temperature.

[0041] Embodiment 2

[0042] As Figures 1-9 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably,

[0043] In this embodiment, a rocker arm 11 is movably connected to the inner wall of one side of the protective shell 1, one end of the rocker arm 11 is fixedly connected to a connecting rod 12, and the other end of the connecting rod 12 is fixedly connected to an inner circular rod 14, which can be used to prevent the speed of smoke and flame spread in the event of a fire. The rocker arm 11 facilitates the recovery of the fire curtain 13 and is also convenient for replacement after recovery.

[0044] The outer wall of the inner round rod 14 is covered with a fire curtain 13, and the outer wall of the fire curtain 13 is fixedly connected with a weighted strip 22, which can reduce the speed of the spread of flame and smoke. The weighted strip can make the fire curtain 13 fall quickly, block the flame and smoke in time, prevent the spread of flame, and buy time for rescue.

[0045] The inner wall of the protective shell 1 is fixedly connected to a second permanent magnet synchronous motor 20, one side of the second permanent magnet synchronous motor 20 is rotatably connected to a locking rod 15, and the outer wall of the locking rod 15 is clamped and connected to a pad 16. When a fire occurs, information is transmitted to the second permanent magnet synchronous motor 20 through a temperature sensor, so that the pad 16 rotates downward through the drive of the locking rod 15, and the fire curtain 13 falls rapidly through the weight-increasing strip 22.

[0046] A second mounting bracket 21 is fixedly connected to the inner wall of the protective shell 1, a temperature sensor 18 is fixedly connected to the bottom inner wall of the protective shell 1, and a similar fan 10 is installed on the second mounting bracket 21 for sucking smoke into the protective shell 1, and then the smoke is sucked into the ventilation pipe 4 through another fan 10. The temperature sensor 18 can transmit a signal to the motor by sensing the ambient temperature so that it can process it in time.

[0047] The following is a detailed description of the working principle of the fire-proof smoke barrier vertical wall.

[0048] like Figures 1-9 As shown, when a fire occurs, the temperature sensor 18 can transmit information to the first permanent magnet synchronous motor 7 and the second permanent magnet synchronous motor 20, so that the fan 10 and the pad 16 rotate. When the pad 16 rotates, the fire curtain 13 will quickly drop through the weight-added strip 22, and promptly stop the spread of flames and smoke. Then the fan 10 will suck the smoke into the protective shell 1, and then another group of fans 10 will suck the smoke into the ventilation duct 4, so as to maintain indoor air circulation, reduce temperature and improve fire resistance.

[0049] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
