Description

Technical Field

[0001] This application relates to the technical field of smoke-proof hanging walls, and particularly to an automatic smoke-proof hanging wall. Background Art

[0002] Smoke-proof hanging walls are commonly used fire protection measures in construction projects and have the functions of fire prevention and smoke separation.

[0003] Smoke-proof hanging walls can be divided into two types according to the installation method: fixed smoke-proof hanging walls and electric smoke-proof hanging walls. The smoke-proof wall body of the fixed smoke-proof hanging wall is installed in a fixed manner, and a smoke-proof hanging wall is set between the top of the building and the clear smoke exhaust height of the space. The fixed smoke-proof hanging wall is fixed above the indoor space of the building both usually and during a fire, which affects the permeability of the indoor space of the building. For spaces such as shopping malls and lobbies that require a tall effect, the space effect is greatly affected.

[0004] Therefore, most of them use electric smoke-proof hanging walls to handle. Usually, the smoke-proof hanging wall is folded under the ceiling of the building or in the decorative ceiling by curling or folding, etc., without affecting the building space effect; when a fire or other dangerous situations occur, after the smoke detector near the electric smoke-proof hanging wall senses the disaster, corresponding instructions are issued through the fire control system in the whole building, and the motor or electric braking mechanism of the electric smoke-proof hanging wall is triggered to unfold the folded smoke-proof hanging wall down to the clear smoke exhaust height, playing the corresponding role of smoke-proof fire protection.

[0005] However, the existing electric smoke-proof hanging walls require the corresponding smoke sensing facilities to be installed and fire protection linkage with the fire control system of the whole building, with a high cost and unable to carry out fire protection work independently.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0038] In combination with reference to Figure 1 、 Figure 2 and Figure 3, in the first embodiment of the present application, an automatic smoke baffle is provided, including a smoke baffle main body 1, the smoke baffle main body 1 is arranged on the bare ceiling 7 or the decorative ceiling 8; a traction mechanism 2, the traction mechanism 2 is connected to the smoke baffle main body 1 and is used to adjust the lifting of the smoke baffle main body 1; a trigger mechanism 3, the traction mechanism 2 is connected to the trigger mechanism 3; a sensing device 4, the sensing device 4 is detachably connected to the trigger mechanism 3; when the sensing device 4 is triggered, the trigger mechanism 3 can be triggered to drive the traction mechanism 2 to move, so as to adjust the lifting of the smoke baffle main body 1.

[0039] Among them, the traction mechanism 2 is connected to the smoke baffle main body 1, and the smoke baffle main body 1 can be lifted by the traction mechanism 2 to prevent the smoke baffle main body 1 from affecting the building space below. The smoke baffle main body 1 can also be curled, folded, or overlapped by the traction mechanism 2, so as to reduce the placement space of the smoke baffle main body 1. The sensing device 4 can sense the temperature change of high-temperature gas and smoke. When the temperature exceeds a certain value, the sensing device 4 can trigger the trigger mechanism 3 to move, thereby driving the traction mechanism 2 to move, and then lowering the smoke baffle main body 1 through the traction mechanism 2. The traction mechanism 2 is detachably connected to the smoke baffle main body 1, which is convenient for installation, maintenance, and replacement. The material of the smoke baffle main body 1 is preferably a non-combustible material, and at the same time has a certain corrosion resistance to prevent aging and deformation due to weather and humidity. In addition, it also has a certain bending strength and can be curled and folded to reduce the required placement space. Specifically, the smoke baffle main body 1 can be a flexible fire curtain, which can be curled up to form a reel usually, occupying a small volume and being convenient for installation; the smoke baffle main body 1 can also be a rigid fire board, which is usually lifted to the position of the bare ceiling 7 or the decorative ceiling 8 of the building to prevent occupying the building space. In case of a fire, the smoke baffle main body 1 is then unfolded downward to the smoke exhaust clear height to prevent the lateral flow of smoke, so as to achieve the smoke baffle effect.

[0040] The sensing device 4 is a device that can sense the temperature change of high-temperature gas and smoke, and can be a liquid glass bulb or a device containing a fusible metal part. A discharge channel is arranged on the device. After the fusible metal part contacts high-temperature gas and smoke, when the temperature exceeds a certain value, it will melt and flow out through the discharge channel, making the device light in weight, thereby reducing the pulling force on the trigger mechanism 3, and then triggering the trigger mechanism 3 to move. Specifically, the balance of the trigger mechanism 3 is broken, and according to the lever principle, the traction mechanism 2 can be pried to drive the smoke baffle main body 1 to move.

[0041] When the liquid glass bulb comes into contact with high-temperature gas and soot, when the temperature exceeds a certain value, the glass bulb will break, and the liquid inside will overflow, making the whole device light in weight, thereby reducing the pulling force on the triggering mechanism 3, and then triggering the movement of the triggering mechanism 3; the sensing device 4 is preferably a liquid glass bulb, which can reduce costs and has a wide range of applications. Moreover, the device containing the fusible metal part and the discharge channel, or the liquid glass bulb, does not need to be connected to the network for temperature sensing and reaction, and can work independently. Specifically, the fusible metal part can be lead-tin alloy, lead-antimony alloy, lead-tin-antimony alloy, etc.; the liquid in the liquid glass bulb can be a low-boiling liquid such as alcohol, which can vaporize when the temperature rises, thereby expanding, causing a change in the air pressure inside the glass bulb, and then bursting.

[0042] The sensing device 4 is detachably connected to the triggering mechanism 3. When the sensing device 4 needs to be repaired or fails, the sensing device 4 can be removed or directly replaced, and the operation is simple and convenient. Specifically, the heights of the sensing device 4 and the smoke baffle main body 1 can be set according to actual needs.

[0043] An automatic smoke baffle in this embodiment includes a smoke baffle main body 1 and a traction mechanism 2. The smoke baffle main body 1 is curled and folded through the traction mechanism 2 and is raised and arranged under the bare ceiling 7 or on the decorative ceiling 8, so as not to affect the building space; when the sensing device 4 senses high-temperature gas or dust and is triggered, the triggering mechanism 3 is triggered successively, driving the traction mechanism 2 to move, thereby controlling and adjusting the lifting of the smoke baffle main body 1, achieving the effect of automatically adjusting the lifting of the smoke baffle main body 1. The whole process is a mechanical movement process, without the need for information linkage with other fire protection systems, can work independently, and has simple components and low costs.

[0044] In some embodiments, the triggering mechanism 3 includes a triggering spring 31 and a first pull rod 32 connected to each other. One end of the first pull rod 32 is connected to the triggering spring 31, and the other end of the first pull rod 32 is connected to the traction mechanism 2; the triggering spring 31 is connected to the sensing device 4.

[0045] When the sensing device 4 is triggered, after the sensing device 4 melts and overflows or overflows from the crack of the glass bulb, the gravity decreases, thereby reducing the pulling force on the triggering spring 31. The triggering spring 31 moves upward according to its elastic restoring force, thereby driving the first pull rod 32 to move upward and tilt, and the traction mechanism 2 connected to the first pull rod 32 moves accordingly, adjusting the lifting of the smoke baffle main body 1. The length of the first pull rod 32 is adjustable, and the length of the first pull rod 32 can be adjusted according to actual needs, thereby adjusting the height of the sensing device 4.

[0046] Combined with reference Figure 4 and Figure 5, Further, the traction mechanism 2 includes a second pull rod 21 and a rotating member 22. The smoke baffle main body 1 is connected to the rotating member 22 and moves following the rotation of the rotating member 22. One end of the second pull rod 21 is connected to the first pull rod 32, and the other end of the second pull rod 21 abuts against the rotating member 22.

[0047] The smoke baffle main body 1 can be curled and overlapped following the rotating member 22, thereby reducing the placement space of the smoke baffle main body 1. When installing the automatic smoke baffle, after curling the smoke baffle main body 1 along with the rotating member 22, the rotating member 22 is abutted against the second pull rod 21, thereby fixing the position of the rotating member 22. The rotating member 22 stops moving, enabling the smoke baffle main body 1 to stably be in the raised state. When the induction device 4 is triggered, the tension force received by the trigger spring 31 changes. The second pull rod 21 moves along with the trigger spring 31 and the first pull rod 32, and the balance of the rotating member 22 is disrupted. Under the action of the gravity of the smoke baffle main body 1, it rotates, causing the smoke baffle main body 1 to unfold downward, separating the building space below, and playing the role of fire prevention and smoke blocking.

[0048] According to fire prevention and smoke blocking requirements, a smoke storage bin is provided in the building. A smoke exhaust opening can be provided on the smoke storage bin. The smoke storage bin is composed of the bare ceiling 7 or the decorative ceiling 8 provided with a smoke baffle, the smoke baffle after drooping, and the side wall of the building. The building can be provided with a lower smoke storage ceiling. After the smoke baffle droops, the smoke baffle connects the bare ceiling 7 with the lower smoke storage ceiling, or the decorative ceiling 8 with the lower smoke storage ceiling, and the side wall of the building to form a smoke storage bin. The lower smoke storage ceiling can position the bottom of the smoke baffle after drooping, facilitating, in special circumstances, blocking the smoke in the smoke storage bin for storage or discharging it through its smoke exhaust opening after the automatic vertical baffle droops, preventing the smoke from spreading to other positions and playing the role of smoke blocking.

[0049] The lower smoke storage ceiling is located below the bare ceiling 7 and the decorative ceiling 8. The smoke baffle is the smoke baffle main body 1 of the present application. The position of the lower smoke storage ceiling is the smoke exhaust clear height where the smoke baffle main body 1 needs to unfold downward.

[0050] A sealing strip can be provided at the bottom of the smoke baffle main body 1. When the smoke baffle main body 1 is unfolded downward to fit with the lower smoke storage ceiling, it can be closely attached to the lower smoke storage ceiling through the sealing strip, preventing smoke and dust from overflowing through the gap between the lower smoke storage ceiling and the smoke baffle main body 1, and improving the fire prevention and smoke blocking effects of the smoke baffle main body 1. Specifically, the sealing strip can be an inverted U-shaped structure. When the smoke baffle main body 1 is unfolded downward, due to the gravity, the sealing strip is closely attached to the lower smoke storage ceiling. At the same time, due to the rapid impact and pressure, the pressure inside the U-shaped area of the sealing strip is discharged, and the internal pressure is lower than the external atmospheric pressure, which can further improve the connection tightness between the sealing strip and the lower smoke storage ceiling, thereby improving the fire prevention and smoke blocking effects of the smoke baffle main body 1. The height of the smoke baffle main body 1 can be 1 - 1.5 m, or longer, and can be set according to actual needs, so that the smoke baffle main body 1 can be unfolded downward to the smoke exhaust clear height, achieving the functions of smoke blocking and fire prevention. Specifically, the minimum height of the smoke baffle main body 1 from the ground is 2.2 m, which is convenient for people below to pass through and can also play a good role in smoke blocking and fire prevention. That is, the lower smoke storage ceiling can be set at a position with a height from the ground of at least 2.2 m, so as to locate the unfolding height of the smoke baffle main body 1.

[0051] The first pull rod 32 is connected to the second pull rod 21. Among them, a number of through holes are provided on the first pull rod 32, and the second pull rod 21 is fixedly connected to the first pull rod 32 through the through holes. Specifically, connection methods such as screws, bolts, and nuts can be used. The through holes on the first pull rod 32 are vertically arranged and are all at different heights. The second pull rod 21 can be connected to the through holes at different heights, so as to adjust the connection length between the first pull rod 32 and the sensing device 4, and further adjust the length of the sensing device 4.

[0052] Specifically, the second pull rod 21 is horizontally arranged, and the first pull rod 32 is vertically arranged, which is convenient for the first pull rod 32 to sense the change in the gravity of the sensing device 4, so as to conduct the force change of the first pull rod 32 to the second pull rod 21, thereby improving the sensitivity of the triggering mechanism 3.

[0053] Furthermore, a first abutting member 211 is provided at one end of the second pull rod 21 close to the rotating member 22, and a second abutting member 221 is provided on the rotating member 22. When the second abutting member 221 abuts and fits with the first abutting member 211, the rotating member 22 stops rotating.

[0054] When installing the smoke baffle main body 1, the smoke baffle main body 1 can be bent and overlapped along the rotation direction of the rotating member 22, and then the second abutting member 221 of the rotating member 22 is abutted and fitted with the first abutting member 211 of the second pull rod 21 to make the rotating member 22 reach balance.

[0055] The abutment and fit between the first abutment member 211 and the second abutment member 221 can balance the gravity of the smoke shielding wall body 1 on the rotating member 22 through the engagement force and friction force between the two, so that the rotating member 22 is in a balanced and stable state, and the rotating member 22 stops moving. The contact surfaces of the first abutment member 211 and the second abutment member 221 can be provided with fine threads and grooves to improve the connection stability between the two, so as to maintain the stable state of the rotating member 22 when the two are connected.

[0056] When the second pull rod 21 of the trigger mechanism 3 moves, the force on the second pull rod 21 acts on the first abutment 211, so that the first abutment 211 is separated from the second abutment 221, and the rotating member 22 cannot maintain balance and rotates under the action of the gravity of the smoke barrier wall body 1, so that the smoke barrier wall body 1 is unfolded downward.

[0057] In some embodiments, the first abutting member 211 is provided with a protrusion 2111, the second abutting member 221 is provided with an abutting groove 2211 corresponding to the protrusion 2111, and the abutting groove 2211 is provided with a limiting rod 2212, and the limiting rod 2212 abuts against the protrusion 2111. Through the abutting groove 2211 and the limiting rod 2212, the first abutting member 211 and the second abutting member 221 can be closely abutted, and the force on the second pull rod 21 is balanced with the gravity of the smoke barrier wall body 1 on the rotating member 22, thereby stabilizing the state of the rotating member 22, so that the curled smoke barrier wall body 1 on the rotating member 22 can be in a raised state.

[0058] Furthermore, a clamping spring 2214 is provided between the limiting rod 2212 and the abutting groove 2211, and the limiting rod 2212 is connected to the abutting groove 2211 through the clamping spring 2214. In order to make the first abutting member 211 and the second abutting member 221 abut tightly, when the first abutting member 211 and the second abutting member 221 are abutted, the clamping spring 2214 is in a compressed or stretched state, and the first abutting member 211 and the abutting groove 2211 are abutted and limited by elastic restoring force.

[0059] When the second pull rod 21 is tilted up or pressed down by force, the first abutment 211 is separated from the second abutment 221, and the clamping spring 2214 returns to its original state under the action of the elastic restoring force, so that the second abutment 221 can no longer fit with the first abutment 211, and the force on the second abutment 221 disappears. The rotating part 22 is only affected by the gravity of the smoke barrier wall body 1, which accelerates the speed at which the smoke barrier wall body 1 unfolds downward, and improves the reaction rate of the smoke barrier wall body 1.

[0060] Specifically, the second abutting member 221 is provided with a groove corresponding to the clamping spring 2214, and the clamping spring 2214 is completely accommodated in the groove, without affecting the abutting and fitting of the first abutting member 211 and the second abutting member 221. The limiting rod 2212 is located on the surface of the first abutting member 211. After the clamping spring 2214 returns to its original position, the limiting member 34 is located at the middle position of the abutting groove 2211, separating and disengaging the first abutting member 211 and the second abutting member 221.

[0061] Further, a guide rod 2213 is provided on the abutting groove 2211, and the clamping spring 2214 is sleeved on the guide rod 2213; one end of the clamping spring 2214 is connected to the limiting rod 2212, and the other end of the clamping spring 2214 is fixedly connected to the abutting groove 2211 through the guide rod 2213.

[0062] The guide rod 2213 guides the clamping spring 2214, facilitating the fixed connection of the clamping spring 2214 and the abutting groove 2211, so that the clamping spring 2214 abuts against and limits the first abutting member 211 in a specific manner, improving the stability when the first abutting member 211 and the second abutting member 221 are connected.

[0063] In some embodiments, the sensing device 4 is a liquid glass bulb, and the sensing device 4 is located below the decorative ceiling 8. In most scenarios, a decorative ceiling 8 is provided below the bare ceiling 7. At this time, if the sensing device 4 is provided on the bare ceiling 7 or between the bare ceiling 7 and the decorative ceiling 8, due to the relatively high setting of the sensing device 4 and the obstruction of the decorative ceiling 8 in the middle, the high-temperature gas and soot are difficult to climb to a relatively high position, resulting in poor sensing effect and low sensitivity of the sensing device 4, making it difficult to reflect in a timely manner. However, when the sensing device 4 is located below the decorative ceiling 8, it can directly contact the high-temperature gas and soot, improving its sensing sensitivity.

[0064] Specifically, the bare ceiling 7 is the main structure of the building, such as the beam in a roughcast house; and the decorative ceiling 8 includes decorative boards, heat-insulating boards, shock-proof boards, etc., which are floor structures added on the basis of the bare ceiling 7. Therefore, when the building includes a decorative ceiling 8, the sensing device 4 is preferably provided below all the decorative ceilings 8 so as to directly contact the high-temperature gas or soot in case of a fire, improving the sensitivity.

[0065] In some embodiments, one end of the smoke baffle main body 1 is connected to the rotating member 22, and a counterweight rod 5 is provided at the other end of the smoke baffle main body 1. When the rotating member 22 loses balance, under the action of the self-weight of the smoke baffle main body 1 and the gravity of the counterweight rod 5, the smoke baffle main body 1 can be quickly unfolded downward. The weight of the counterweight rod 5 can be adjusted according to the connection strength between the first abutting member 211 and the second abutting member 221, so that when the first abutting member 211 and the second abutting member 221 are abutted and fitted, the rotating member 22 can be in a balanced state, and the smoke baffle main body 1 can be stably in the raised state.

[0066] Further, the rotating member 22 can be provided with an additional rotating spring (not marked in the figure). Driven by the rotational traction force of the additional rotating spring, the smoke baffle main body 1 can be unfolded downward more quickly to play a smoke-blocking and fire-fighting role more quickly.

[0067] The height of the smoke baffle main body 1 can be the height of the internal space of the building, that is, the counterweight rod 5 can directly fall to the clear smoke exhaust height and contact the lower smoke storage ceiling to make a sound, playing a reminder role. An inductor can be provided on the counterweight rod 5. After the counterweight rod 5 falls, the inductor senses the force change of the counterweight rod 5, thereby being triggered to send an alarm signal or directly emit an alarm bell to give a reminder, so that the nearby personnel can clearly know the location information of the fire and take timely measures. In addition, the smoke baffle main body 1 can be painted with oil paint to enhance its heat insulation and fire prevention performance, and fluorescent warning words can be painted on the paint surface, so that when it is unfolded, the nearby people can observe its prominent warning words and thus stay away from here or take fire-fighting measures.

[0068] In addition, in order to prevent the inductor from failing due to temperature change and resulting in the inability to play a reminder effect, a sound generating component can be provided at the bottom of the counterweight rod 5. The sound generating component contains a rubber hollow structure with a kazoo structure. When the smoke baffle main body 1 is unfolded downward, the counterweight rod 5 falls first, causing the sound generating component below it to be pressed, and the volume of the internal hollow structure changes, causing the air pressure to change, and then making a sound; the sound is special and has strong penetrability, which can play an excellent reminder role and will not be affected by the fire or signal reasons for its sound generation; and the sound generating component can be made of rubber material.

[0069] Further, the automatic smoke baffle further includes a rolling shutter box 11, and the smoke baffle main body 1 and the rotating member 22 are both located in the rolling shutter box 11. The rolling shutter box 11 serves as a protection device for the smoke baffle body. The rolling shutter main body and the rotating member 22 are arranged inside the rolling shutter box 11, which can prevent impurities and water vapor from entering the rolling shutter box 11 and then damaging the smoke baffle main body 1 and the rotating member 22.

[0070] Specifically, one end of the additional rotation spring is arranged at the center of the rotating member 22; the other end is arranged on the shutter box 11 along with the curling of the smoke barrier wall body 1, and is thus rotated to the periphery of the center of the rotating member 22 and connected to the second abutment member 221. When the balance of the rotating member 22 is broken, the elastic restoring force of the additional rotation spring can drive the second abutment member 221 to rotate in the opposite direction of the curling of the smoke barrier wall body 1, thereby accelerating the downward extension speed of the smoke barrier wall body 1.

[0071] Combined with reference Figure 6 Further, a fixing member 33 is provided between the shutter box 11 and the trigger mechanism 3, and the fixing member 33 is used to connect the shutter box 11 and the trigger mechanism 3. The fixing member 33 can stably connect the shutter box 11 and the trigger mechanism 3, thereby fixing the position of the trigger mechanism 3.

[0072] A limit member 34 can also be provided on the trigger mechanism 3, and the limit member 34 abuts against the second pull rod 21, so that the second pull rod 21 is in a horizontal state with the ground, and the second pull rod 21 is perpendicular to the first pull rod 32. When the sensing device 4 senses high-temperature gas and smoke, the gravity changes, and the vertical force on the first pull rod 32 changes, thereby moving vertically, causing the second pull rod 21 to be unbalanced in the vertical direction; at this time, the first abutment 211 and the second abutment 221 are horizontally connected, and the connection is mainly stabilized by lateral friction. When the second pull rod 21 is unbalanced in the vertical direction, vertical force appears on the first abutment 211 and the second abutment 221, which makes it easier to destroy the stable connection relationship between the first abutment 211 and the second abutment 221, thereby causing the rotating member 22 to be unbalanced, and the smoke barrier vertical wall body 1 is unfolded downward.

[0073] Furthermore, the outer wall of the sensing device 4 is meshed with the inner wall of the trigger mechanism 3; that is, the outer wall of the sensing device 4 and the inner wall of the trigger mechanism 3 are provided with corresponding threads, which can be connected by threaded meshing, thereby improving the connection stability of the two. A smoke alarm can be provided next to the sensing device 4. When the sensing device 4 reacts, the smoke alarm is triggered at the same time to spray, respond to the fire in the first time, and achieve the effect of extinguishing the fire. In addition, the outer wall of the sensing device 4 and the inner wall of the trigger mechanism 3 can also be connected by a fixing clip, so that the sensing device 4 can adjust the upper and lower installation heights according to the height of the bare ceiling 7 or the decorative ceiling 8 to ensure that it is installed under the decorative ceiling 8.

[0074] The trigger mechanism 3 can be connected to the sensing device 4 through the first pull rod 32 and the trigger spring 31, so that the height of the sensing device 4 can be adjusted by adjusting the length of the first pull rod 32; the sensing device 4 can also be engaged with the trigger mechanism 3, and the height of the sensing device 4 can be adjusted by adjusting the height of the trigger mechanism 3. Among them, the liquid glass bubble of the sensing device 4 is connected through the trigger spring 31. When the liquid glass bubble is subjected to high-temperature gas or smoke and explodes, the tension on the trigger spring 31 changes, thereby driving the first pull rod 32 and the second pull rod 21 to move, thereby destroying the balance of the rotating member 22, so that the smoke barrier vertical wall body 1 is unfolded downward under the action of its own gravity and the counterweight rod 5 to a clear height for smoke exhaust.

[0075] In some embodiments, the smoke barrier wall body 1 is located on the bare ceiling 7; or, the smoke barrier wall body 1 is located on the decorative ceiling 8; or, the smoke barrier wall body 1 is located between the bare ceiling 7 and the decorative ceiling 8, and the decorative ceiling 8 is provided with a through groove corresponding to the smoke barrier wall body 1.

[0076] The smoke barrier wall body 1 can be set on the bare ceiling 7 or the decorative ceiling 8 without affecting the building space below; when a fire occurs, it can be expanded downward by sensing abnormal temperature and smoke, thereby achieving the effect of smoke blocking and fire prevention; therefore, if the building ceiling includes a bare ceiling 7 and a decorative ceiling 8, then the decorative ceiling 8 should be provided with a through groove corresponding to the smoke barrier wall body 1, so as to facilitate the downward expansion of the smoke barrier wall body 1.

[0077] Preferably, when the building includes a bare roof 7 and a decorative ceiling 8, the smoke barrier wall body 1 is disposed between the bare roof 7 and the decorative ceiling 8, making full use of the space between the two to hide the smoke barrier wall body 1, thereby improving the utilization rate of the building space. The bare roof 7 and the decorative ceiling 8 can be connected via a keel connector 71.

[0078] A hanger 6 is provided on the main body 1 of the smoke barrier wall. The ceiling can use angle steel as the keel, one end of which is connected to the main body of the building through the hanger 6, such as a bare ceiling 7 or a decorative ceiling 8 and other structural floors, and the other end fixes the main body 1 of the smoke barrier wall to the keel of the hanger 6; at the same time, the sensing mechanism and the traction mechanism 2 can also be fixedly connected to the keel.

[0079] In summary, the present application provides an automatic smoke baffle, which includes a smoke baffle main body and a traction mechanism. The smoke baffle main body is curled and folded through the traction mechanism and is raised and arranged under the bare ceiling or on the decorative ceiling, so as not to affect the building space. When the induction device senses high-temperature gas or dust and is triggered, the triggering mechanism is successively triggered to drive the traction mechanism to move, thereby controlling and adjusting the lifting of the smoke baffle main body, achieving the effect of automatically adjusting the lifting of the smoke baffle main body. The whole process is a mechanical movement process, without the need for information linkage with other fire protection systems, can work independently, and has simple components and low cost.

Although the present application has been described in detail with reference to the foregoing examples, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing examples, or perform equivalent replacements for some of the technical features. These modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the present application.
