Description

Technical Field

[0001] The utility model relates to the field of building smoke prevention and exhaust, in particular to a flap type smoke baffle combined with a suspended ceiling. Background Art

[0002] Fixed smoke baffles are usually made of non-combustible materials, generally not less than 500 mm in height, and are installed on the building ceiling, cross beam or under the suspended ceiling. Although this structure can effectively block the lateral diffusion of smoke and confine the smoke in a specific area for discharge, its fixed nature results in occupying a certain building net height and may affect the aesthetics of the building, especially in buildings with relatively low storeys. In contrast, movable smoke baffles are mostly made of light materials such as inorganic fiber fabrics, and are usually retracted into the suspended ceiling during normal times, without affecting the clear space below the suspended ceiling.

[0003] However, movable smoke baffles also have defects. Their movable parts need to be installed above the suspended ceiling, still occupying a certain height space and may, to a certain extent, hinder the installation of other pipes inside the suspended ceiling. More importantly, movable smoke baffles are prone to swing under the influence of smoke or wind (such as when the smoke exhaust fan starts), thus affecting their smoke blocking effect. In addition, existing movable smoke baffles mostly rely on motors to control their deployment and contraction, and these motors are prone to be damaged in the high-temperature environment of a fire, thus affecting their reliability and effect. Therefore, based on the defects of smoke baffles in the current existing technologies, it is necessary to provide a more optimized improved design. Summary of the Utility Model

[0004] In view of the above defects or requirements for improvement in the prior art solutions, the utility model provides a flap type smoke baffle combined with a suspended ceiling, aiming to solve the technical problems of inconvenient deployment and contraction of existing smoke baffle devices, complex lifting structure with high cost, and inability to ensure the normal lowering of the smoke baffle during a fire.

[0005] To achieve the above object, the technical solution of the utility model is as follows: A flap type smoke baffle combined with a suspended ceiling, comprising a smoke baffle, a rotating mechanism, a control mechanism, an upper cover plate, a signal module, and a control box; the rotating mechanism includes a rotating shaft, a bearing, and an auxiliary contact, the auxiliary contact is fixedly connected to the rotating shaft and rotates with the rotating shaft, and the signal module can convert the position of the auxiliary contact into an electrical signal and feedback it to the control box or the fire control room; one end of the smoke baffle is fixedly connected to the rotating shaft, and a round hole is provided at the center position of the other end. In a non-fire state, the smoke baffle is flush with the suspended ceiling; the upper cover plate is located in the suspended ceiling space above the smoke baffle and fits with the smoke baffle; the control mechanism includes an electromagnet, and the control box controls the on-off of the circuit of the electromagnet based on the fire state.

[0006] The utility model combines a smoke baffle with a ceiling. Usually, it is retracted and flush with the ceiling, and can be used as a ceiling, without occupying the building's net clear height and the space inside the ceiling, without affecting the aesthetics. In case of a fire, it can automatically turn down and be in place, effectively blocking and controlling the lateral diffusion of smoke, and realizing the function of blocking and preventing smoke. Specifically, through the collaborative work of a smoke baffle, a rotating mechanism, an upper cover plate, a signal module, a control mechanism, and a control box, the smoke baffle can quickly respond and turn downwards accurately and deploy during a fire, effectively blocking the smoke, and improving the safety and evacuation efficiency during a fire.

[0007] Preferably, the control mechanism further includes a temperature fuse, a pull rod, a hanging lock, and a bolt. One end of the pull rod is a ring, and the other end is used to connect the temperature fuse and passes through a round hole on the smoke baffle. The hanging lock has two lock holes, and the bolt passes through the lock holes and the ring at the end of the pull rod to hinge the pull rod and the hanging lock.

[0008] Preferably, the electromagnet is perpendicular to the plane of the smoke baffle and is fixedly connected to the smoke baffle. The electromagnet is connected to the control box through the cable.

[0009] Preferably, it further includes a smoke detector, which is arranged under the ceiling near the smoke baffle, and is used to detect smoke and send an alarm signal to the control box or the fire control room.

[0010] Preferably, when the temperature of the temperature fuse reaches a preset value, it melts and disengages from the pull rod, allowing the smoke baffle to turn down along the rotating shaft under its own weight to a vertical state.

[0011] Preferably, the signal module includes two sets of terminal blocks, one set is used to feedback signals to the control box, and the other set is used to feedback signals to the fire control room.

[0012] Preferably, when the smoke baffle turns downwards, the control box can simultaneously send an instruction to the sound and light alarm, and the sound and light alarm issues a voice prompt and a light prompt.

[0013] Preferably, the control box is installed on the side wall near the smoke baffle.

[0014] The beneficial effects of the utility model are as follows:

[0015] (1) The design of combining the smoke baffle of the utility model with the ceiling makes it flush with the ceiling in the non-fire state, which is used as a part of the ceiling and does not occupy the building's net clear height and the space inside the ceiling. This design not only optimizes the space utilization but also maintains the aesthetics of the building interior. In case of a fire, the smoke baffle can automatically turn down and be in place, quickly realizing the function of blocking and preventing smoke, and effectively restricting the diffusion of smoke.

[0016] (2) The smoke baffle of the present utility model can automatically fuse and close according to the alarm signal of the smoke detector or when the temperature reaches 70°C, and feedback the status to the control system. At the same time, it supports on-site manual control and remote control operations, which enhances the reliability and flexibility of the system and meets the control requirements of modern smoke prevention and exhaust equipment. The smoke baffle with a plate structure has a large structural strength and can effectively resist the swing caused by wind, thus ensuring excellent smoke blocking and smoke prevention effects.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the present utility model.

[0024] In addition, the described features, structures, or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, numerous specific details are provided to give a thorough understanding of the embodiments of the present application. However, those skilled in the art will realize that the technical solutions of the present application can be practiced without one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, well-known methods, devices, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the present application.

[0025] As Figure 1 shown, this embodiment provides a flip-type smoke baffle combined with a suspended ceiling, including a smoke baffle 1, a rotating mechanism 2, a control mechanism 3, an upper cover plate 4, a signal module 5, and a control box 8; the rotating mechanism 2 includes a rotating shaft 21, a bearing 22, and an auxiliary contact 25. The auxiliary contact 25 is fixedly connected to the rotating shaft 21 and rotates with the rotating shaft 21. The signal module 5 can convert the position of the auxiliary contact 25 into an electrical signal and feedback it to the control box 8 or the fire control room; one end of the smoke baffle 1 is fixedly connected to the rotating shaft 21 and rotates with the rotating shaft 21. A circular hole is provided at the center position of the other end. In the non-fire state, the smoke baffle 1 is flush with the suspended ceiling; the upper cover plate 4 is located in the suspended ceiling space above the smoke baffle 1 and fits closely with the smoke baffle 1; the control mechanism 3 includes an electromagnet 36, and the control box 8 controls the on-off of the circuit of the electromagnet 36 based on the fire state.

[0026] Furthermore, the lower surface of the smoke baffle 1 uses the same material and color as the suspended ceiling, so that the smoke baffle 1 merges with the suspended ceiling in the horizontal state, maintaining the aesthetics and consistency of the interior of the building. A damping facility can be set on the bearing 21 to ensure that the smoke baffle 1 slowly flips downwards, without being too fast and causing danger, improving the safety of the system, especially in case of emergency. A limiting device is provided at the vertical position after the smoke baffle 1 flips down, which can be an angle steel or a baffle rod, etc., to prevent the smoke baffle 1 from shaking after flipping down into place, not only ensuring the stability of the smoke baffle after it is in place, but also improving the reliability and durability of the entire system. The upper cover plate 4 is made of non-combustible material and fits closely with the smoke baffle 1.

[0027] As Figure 2 shown, the rotating mechanism 2 includes a rotating shaft 21, a bearing 22, a support plate 23, a fixing bolt 24, and an auxiliary contact 25. The support plate 23 is connected to the bearing 22 and is installed on the walls on both sides through the fixing bolt 24. The two ends of the rotating shaft 21 are inserted into the bearing 22 and can rotate freely. The auxiliary contact 25 is fixedly connected to the rotating shaft 21 and rotates with the rotating shaft 21.

[0028] The smoke detector 7 is placed under the ceiling near the smoke baffle, detecting smoke and sending an alarm signal to the control box 8 or the fire control room. The fire control room is the central monitoring point of the building, responsible for monitoring the safety systems of the entire building. Through this set of terminal blocks, the signal module 5 can transmit the status information of the smoke baffle to the fire control room in real time, ensuring that the building safety management personnel can quickly understand and respond to the fire situation.

[0029] As Figure 3 shown, the control mechanism 3 includes a thermal fuse 31, a pull rod 32, a hanging lock 33, a bolt 35, and an electromagnet 36. One end of the pull rod 32 is a ring with a diameter larger than the round hole, and the other end is used to connect to the thermal fuse 31; this pull rod passes through the round hole on the smoke baffle 1, with a ring on the board and the thermal fuse 31 connected under the board. The thermal fuse 31 is located in the concave hole of the smoke baffle 1. When the temperature reaches 70 °C, the thermal fuse 31 melts and disengages from the pull rod 32.

[0030] The hanging lock 33 has two locking holes 34. The bolt 35 can sequentially pass through the locking holes 34 and the ring at the end of the pull rod 32 to hinge the pull rod 32 and the hanging lock 33 together. The hanging lock 33 is connected to the hanging rod 9, and the hanging rod 9 is fixed under the beam slab. The electromagnet 36 is fixedly connected to the smoke baffle 1 perpendicular to the plane of the smoke baffle 1, and the electromagnet 36 is connected to the control box 8 through a cable 6.

[0031] The control box 8 is installed on the side wall near the smoke baffle. The signal module 5 is installed on the side wall or placed on the keel, and can convert the position state of the auxiliary contact 25 into an electrical signal and feedback it to the control box 8 or the fire control room.

[0032] As Figure 4 shown, the signal module 5 includes two sets of terminal blocks. One set is used to feedback signals to the control box 8, and the other set is used to feedback signals to the fire control room. The control box is installed near the smoke baffle and is directly responsible for monitoring and controlling the behavior of the smoke baffle. When the state of the smoke baffle changes, the signal module 5 immediately sends the signal of the state change to the control box 8 through this set of terminal blocks.

[0033] Furthermore, the installation height of the control box 8 is 1.3 - 1.5 m. This height range is convenient for operators to perform daily operations and maintenance, and also ensures easy access and visibility. When the smoke baffle 1 is flipped downwards, the control box 8 can simultaneously send instructions to the audible and visual alarm. The audible and visual alarm emits voice prompts and light prompts to remind the evacuated crowd to pay attention to safety. This immediate audible and visual alarm mechanism is crucial for ensuring personnel safety in emergency situations. The control box 8 can reserve an interface for the FAS system, facilitating connection to the disaster prevention or fire control room platform. The duty personnel can remotely control the opening and closing of the smoke curtain wall in the fire control room. This remote control function makes the system response more flexible and timely. The control box 8 can display the opening and closing status of the smoke curtain wall in real time through a liquid crystal display. Through the intuitive display, the operator can easily monitor the current status of the smoke curtain wall, ensuring immediate understanding and effective management of the system.

[0034] The smoke curtain wall mainly has two state modes: non-fire mode and fire mode. In the non-fire mode, the smoke baffle 1 and the upper cover plate 4 are suspended under the beam and slab by the tie rod 32 and the hanging lock 33, flush with the ceiling. At this time, the auxiliary contact position is at the "0" position, and the status output from the signal module 5 to the control box 8 or the fire control room is open. In case of a fire, the smoke detector 7 detects the smoke signal and sends an alarm signal to the control box 8 or the fire control room. After confirming the fire, it can be manually controlled by the control box 8 or the fire control room. A pulse is sent from the control box 8 to the electromagnet 36. After the electromagnet 36 is energized, the latch 35 is sucked out by magnetic force, and the tie rod 53 is disengaged from the hanging lock 44. The smoke baffle 1, together with the temperature fuse 31, the tie rod 32, the electromagnet 36, and the latch 35, rotates downwards along the rotating shaft 21 to the vertical position. At the same time, the stainless steel mesh plate 10 slides out of the smoke baffle. At the same time, the auxiliary contact 25 position is at the "1" point, and the signal module 5 outputs a closing signal to the control box 8 or the fire control room. If the smoke detector 7 or the control mechanism 3 fails, the smoke accumulates under the ceiling. When the smoke temperature reaches 70 °C, the temperature fuse 31 melts, and the smoke baffle 1 disengages from the tie rod 32 under its own weight and rotates downwards from the ceiling position along the rotating shaft 21 until it reaches the vertical state, which can also achieve the function of blocking smoke. At this time, the auxiliary contact 25 position is at the "1" point, and the signal module 5 outputs a closing signal to the control box 8 or the fire control room.

[0035] In this embodiment, the smoke baffle system ensures rapid and effective deployment in the event of a fire through intelligent control and automatic response mechanisms, maximizing the control of smoke diffusion while maintaining the aesthetics and functionality of the building. The temperature fuse 31 provides an important safety guarantee for the smoke baffle system. Especially in the case of a malfunction of the smoke detector 7 or the control mechanism 3, the temperature fuse 31 provides an automatic safety response mechanism. Once the smoke temperature reaches 70 °C, the temperature fuse will automatically blow, triggering the drooping action of the smoke baffle, thus ensuring that the smoke baffle can be deployed in a timely manner at a critical moment. This temperature-based automatic activation mechanism enhances the reliability of the system. As a passive safety measure, it does not rely on external power sources or complex electronic control systems and is therefore still effective in the event of electrical or electronic failures.

[0036] After the fire is over, it can be reset manually (in the case of non-fusing) or by re-welding the temperature fuse 31 (in the case of fusing). During normal maintenance, the smoke baffle 1 can be manually controlled to flip downward to the vertical position through the control box 8. The inspection opening should be set near the control mechanism 3 for easy manual reset and other operations.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it; under the concept of the present invention, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above. For the sake of brevity, they are not provided in detail; 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 recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention.
