[0002] Currently, large buildings such as shopping malls, theaters, and garages need to install smoke curtains or smoke screens on the ceilings of their interiors. This is to control the smoke generated in the early stages of a fire within a certain range, thereby preventing the spread of toxic smoke to other areas. It can effectively control toxic smoke within the smoke control zone and discharge the toxic smoke from the burned area through the smoke exhaust duct, so as to facilitate the rapid evacuation of personnel and the timely entry of firefighters, protect the safety of life and property, and buy valuable time for fire fighting.

[0003] Traditional smoke curtains typically use wired or single-pane glass as the main smoke barrier. Due to foundation settlement and construction issues, buildings may deform, causing deformation of walls or beams. Smoke curtains installed on ceilings or beams become deformed under external stress, making them difficult to remove and affecting daily maintenance.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0007] The present invention is further configured such that: the bottom of the mounting strip is provided with a mounting groove, the cross-section of the mounting groove is T-shaped, and a plurality of disassembly ports are provided on the opening of the mounting groove; the top frame is a long rectangular prism, and a connector is provided on the top surface of the top frame; the connector extends into the mounting groove, and a plurality of limiting blocks with the same shape and size as the disassembly ports are provided on the long side end faces of the connector.

[0008] The present invention is further configured such that: the bottom frame is a long rectangular parallelepiped, and the bottom surface of the top frame and the top surface of the bottom frame are provided with connecting grooves for placing the smoke baffle; the smoke baffle is configured as a plate-like structure, and its upper and lower ends extend into the connecting grooves of the top frame and the bottom frame, respectively.

[0009] The present invention is further configured such that the coefficient of friction between the smoke baffle and the connecting groove is 0.5-0.6.

[0010] The present invention is further configured such that: the flexible component is a long rectangular parallelepiped structure, and the upper and lower ends of the flexible component abut against the side walls of the top frame and the bottom frame, respectively.

[0011] The present invention is further configured such that the flexible component is made of halogen-free flame-retardant TPE material.

[0012] The present invention is further configured such that a smoke alarm is provided on the outer side of the top frame.

[0013] In summary, this utility model has the following beneficial effects: the mounting strip is movably connected to the top frame, a smoke baffle is detachably connected to the bottom of the top frame, a bottom frame is detachably connected to the bottom of the smoke baffle, and flexible components are detachably connected to the two side walls of the smoke baffle.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Automatic alarm type smoke curtain, such as Figure 1As shown, it includes an installation strip 2, a top frame 3 movably connected to the bottom of the installation strip 2, a smoke baffle 1 detachably connected to the bottom surface of the top frame 3 away from the installation strip 2, a bottom frame 4 detachably connected to the bottom surface of the smoke baffle 1, and flexible parts 5 detachably connected to the two side walls of the smoke baffle 1. The flexible parts 5 between two adjacent smoke baffles 1 abut against each other and can resist the stretching and shrinking of the smoke baffle 1 caused by the deformation of the wall.

[0021] like Figure 4 As shown, the mounting strip 2 is a long, rectangular structure. It is installed on a ceiling or beam. A mounting groove 21 is formed on the ground-facing end of the mounting strip 2, penetrating both side walls. The mounting groove 21 has a T-shaped cross-section, and its opening has several disassembly ports 22 distributed on both sides of the opening. These ports connect to the mounting groove 21. Figure 3 As shown, the top frame 3 is a long rectangular prism. A connector 31 is provided on the end face facing the mounting strip 2. The connector 31 is also a long rectangular prism and is located at the center of its end face. The connector 31 extends into the mounting groove 21, and the top surface of the connector 31 abuts against the bottom surface of the mounting groove 21. Several limiting blocks 32 are provided on the two side walls of the connector 31. The cross-sectional shape of the limiting blocks 32 is consistent with the cross-sectional shape of the disassembly port 22, and their positions on the connector 31 are consistent with the positions of the disassembly port 22 on the mounting groove 21. The top frame 3 slides into the mounting groove 21 through the connector 31. The top frame 3 and the mounting strip 2 are slidably and detachably connected. When the top frame 3 is slidably connected to the mounting strip 2, the disassembly port 22 and the limiting blocks 32 cooperate. When the top frame 3 slides, the limiting blocks 32 slide to the position of the disassembly port 22, and the top frame 3 can move down and detach from the mounting strip 2, improving its portability and facilitating disassembly and assembly.

[0022] like Figure 2 and Figure 3 As shown, the bottom frame 4 is a long rectangular cuboid, and the end face of the top frame 3 facing the ground and the end face of the bottom frame 4 facing the top frame 3 are provided with connecting grooves 6. The connecting grooves 6 penetrate through the two side walls of the top frame 3 and the bottom frame 4. The cross-section of the connecting grooves 6 is rectangular. The connecting grooves 6 are used to place the smoke baffle 1. The smoke baffle 1 has a plate-like structure. The length of the top frame 3 and the bottom frame 4 is the same as the length of the smoke baffle 1. The upper and lower ends of the smoke baffle 1 extend into the connecting grooves 6 provided on the top frame 3 and the bottom frame 4, respectively. Preferably, the coefficient of friction between the smoke baffle 1 and the connecting groove 6 is between 0.5 and 0.6. The high coefficient of friction allows the smoke baffle 1 to be better connected to the top frame 3 and the bottom frame 4 and is not easy to fall off. The mounting strip 2, the top frame 3 and the bottom frame 4 are all made of aluminum alloy. Aluminum alloy has the characteristics of low density, high strength, high plasticity, good electrical and thermal conductivity, good corrosion resistance and easy processing.

[0023] like Figure 2As shown, the flexible component 5 has a long rectangular parallelepiped structure. One end face of the flexible component 5 is attached to the side wall of the smoke baffle 1, and the height of the flexible component 5 is equal to the sum of the heights of the top frame 3, the smoke baffle 1, and the bottom frame 4. The upper and lower ends of the flexible component 5 abut against the side walls of the top frame 3 and the bottom frame 4, respectively. Fixing grooves 41 are provided on the two side walls of the bottom frame 4. A protrusion 51 is provided at the bottom of one end face of the flexible component 5, and the protrusion 51 extends into the fixing groove 41. The flexible component 5 and the bottom frame 4 are detachably connected. The end faces of the flexible components 5 between two adjacent smoke baffles 1 are attached to each other. During installation, opposing forces are applied to the two smoke baffles 1 to make the two adjacent flexible components 5 fit tightly together, causing them to undergo elastic deformation to resist the tension caused by the deformation of the wall and maintain the proper smoke baffle function. Preferably, the flexible component 5 is made of halogen-free flame-retardant TPE material. Halogen-free flame-retardant TPE material is a material with the high elasticity, high strength, and high resilience of rubber, and also has the characteristics of being injection moldable.

[0024] like Figure 1 As shown, a smoke detector 7 is installed on the outer side of the top frame. The smoke detector 7 is electrically connected to the power supply. In the event of a fire, the smoke detector 7 will sound an alarm after detecting that the smoke concentration has reached a preset value, which will serve as an early warning and increase the time for people to escape, thereby reducing casualties.

[0025] When installing this automatic alarm smoke curtain, first fix the mounting strip 2 to the ceiling or beam using expansion screws. Then slide the top frame 3 into the mounting groove 21 at the bottom of the mounting strip 2. The limiting block 32 on the top frame 3 and the disassembly port 22 on the mounting groove 21 are misaligned. The top frame 3 is fixed to the mounting strip 2. Insert one end of the smoke curtain 1 into the connecting groove 6 on the bottom surface of the top frame 3, and insert the other end of the smoke curtain 1 into the connecting groove 6 on the top surface of the bottom frame 4. Due to the friction coefficient between the inner wall of the connecting groove 6 and the outer wall of the smoke curtain 1, the smoke curtain 1 can be firmly connected to the top frame 3 and the bottom frame 4. Flexible parts 5 are provided on both sides of the smoke curtain 1. One end of the flexible part 5 fits the side wall of the smoke curtain 1, the top frame 3, and the bottom frame 4. The flexible part 5 is made of halogen-free flame-retardant TPE. The material possesses excellent deformation capacity and flame-retardant properties. The flexible parts 5 between two adjacent smoke curtains 1 abut against each other, and during installation, the two smoke curtains 1 are pressed together, causing the two adjacent flexible parts 5 to deform. This resists the stretching and compression caused by the wall deformation, allowing the smoke curtain to maintain its normal smoke-blocking function. The flexible parts 5 and the detachable connection between the top frame 3 and the mounting strip 2 allow the smoke curtain to be disassembled even when the wall deforms, enabling routine maintenance and repair work and enhancing its safety. In locations where this automatic alarm type smoke curtain is installed, if the smoke concentration exceeds a predetermined threshold during a fire, the smoke alarm 7 detects the smoke and sounds an alarm, promptly reminding personnel to evacuate, increasing escape time and reducing casualties.
