Description

Technical Field

[0001] The invention relates to the technical field of building fire protection engineering, and in particular to a movable vertical smoke barrier wall for building fire protection. Background Art

[0002] Smoke barrier is an important fire protection facility, mainly used in office buildings, large shopping malls, office buildings, warehouses and other buildings. In the event of a fire, the fire smoke barrier is controlled to fall as non-combustible fireproof cloth, effectively blocking the horizontal flow of smoke under the building ceiling, thereby improving the smoke exhaust effect in the smoke-proof partition to protect people's lives and property. The movable smoke barrier for building fire protection is mainly divided into fixed and movable types. The fixed smoke barrier is fixedly installed on the building, and its sagging height should be no less than 500mm, and the material is required to be non-combustible. The movable smoke barrier droops due to the action of temperature, smoke or other control equipment during a fire to form a smoke-proof partition. The movable smoke barrier is installed later after the building is decorated. Due to size issues, it needs to be measured and reserved in advance, and the ceiling needs to be dismantled and hidden in the ceiling. The construction space is limited and the construction is inconvenient. In addition, after the functional area of ​​the building is changed, the smoke barrier installed at the original location needs to be removed and installed at the new location, which makes the removal process of the movable smoke barrier more cumbersome. In addition, the movable smoke barrier is usually powered by wires. When the wires catch fire, the movable smoke barrier loses power supply and cannot control the rotation of the reel through the drive mechanism formed by the motor, sprocket, and chain to control the droop of the fireproof cloth, resulting in the failure of the movable smoke barrier and the inability to form a smoke-proof partition. Moreover, the speed of the drive mechanism to control the droop of the fireproof cloth is slow, which affects the smoke barrier efficiency. Summary of the invention

[0003] The purpose of the present invention is to provide a movable smoke barrier wall for building fire protection, so as to solve the problem that the fireproof cloth of the smoke barrier wall cannot be controlled to droop through the driving mechanism formed by the motor, sprocket and chain to form a smoke-proof partition due to a fire caused by electric wires.

[0004] In order to solve the above technical problems, the technical solution provided by the present invention is: a movable smoke barrier wall for building fire protection, comprising two suspension rods, a reel rotatably connected between the two suspension rods, a fireproof cloth rolled up on the reel, and a gravity rod parallel to the reel connected to the lower end of the fireproof cloth. A control box is provided on one of the suspension rods, and a controller and a smoke sensor and an electromagnetic plug connected thereto are provided in the control box. When the smoke sensor does not detect a smoke signal, the controller controls the electromagnetic plug to be inserted into a slot provided on the reel to lock the reel, and the fireproof cloth remains rolled up on the reel; when the smoke sensor detects a smoke signal, the controller controls the electromagnetic plug to be pulled out of the slot of the reel to unlock the reel, and the fireproof cloth is unfolded downward from a rolled up state to a drooping state by the gravity of the gravity rod.

[0005] Furthermore, in the movable smoke barrier wall for building fire protection provided by the present invention, an electromagnetic pin connected to the controller is provided on another suspension rod, and the electromagnetic pin on the other suspension rod is aligned with a slot provided on the reel at its corresponding position.

[0006] Furthermore, in the movable smoke barrier wall for building fire protection provided by the present invention, the controller is connected to a fire monitoring center. When the fire monitoring center sends out a fire signal, the controller controls the electromagnetic latch to be pulled out from the slot of the reel to unlock the reel.

[0007] Furthermore, the movable vertical smoke barrier wall for building fire protection provided by the present invention also includes a power supply device connected to the controller.

[0008] Furthermore, in the movable smoke barrier vertical wall for building fire protection provided by the present invention, the power supply device includes a battery.

[0009] Furthermore, in the movable smoke barrier wall for building fire protection provided by the present invention, the power supply device also includes an acoustic-to-electric conversion device connected to a battery and a controller, the acoustic-to-electric conversion device includes an acoustic energy collection device and a capacitive transducer, the capacitive transducer is a variable capacitor composed of a diaphragm and a rear plate, the incident sound wave is transmitted to the diaphragm through the acoustic energy collection device, the vibration of the diaphragm causes the variable capacitance to change, and the sound energy is converted into electrical energy.

[0010] Furthermore, in the movable smoke barrier wall for building fire protection provided by the present invention, the power supply device is connected to a charging indicator light and a full-charge indicator light, and the sound energy conversion equipment is connected to a sound wave sensing indicator light.

[0011] Furthermore, in the movable vertical smoke barrier wall for building fire protection provided by the present invention, a hand wheel is provided at the end of the reel located outside the suspension rod.

[0012] Furthermore, in the movable vertical smoke barrier wall for building fire protection provided by the present invention, the reel is rotatably connected to the suspension rod via a bearing.

[0013] Furthermore, in the movable smoke barrier vertical wall for building fire protection provided by the present invention, the gravity rod is a round rod or a flat rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The movable smoke barrier for building fire protection provided by the present invention, when the smoke sensor detects a smoke signal, the controller controls the electromagnetic plug to be pulled out from the slot of the reel to unlock the reel, and the gravity of the gravity rod can quickly drive the fireproof cloth to rotate the reel, so that the fireproof cloth is unfolded downward from a curled state to a drooping state, quickly forming a smoke-proof partition, and quickly blocking smoke from entering the smoke control area. Compared with the drive mechanism composed of a motor, a sprocket, and a chain that controls the drooping of the fireproof cloth by rotating the reel, it has the advantages of fast drooping speed and rapid formation of smoke-proof partitions. After the electromagnetic plug loses power due to a fire in the electric wire, it can be pulled out from the slot of the reel to unlock the reel, and the fireproof cloth can be drooped, which is not affected by the power failure caused by the fire in the electric wire, and overcomes the problem that the traditional drive mechanism cannot control the fireproof cloth to droop to form a smoke-proof partition after power failure. During the initial installation, the electromagnetic plug is inserted into the slot on the reel to keep the reel in a locked state and the fireproof cloth in a curled state. It is suspended on the indoor roof of the building through a hanging rod and is not hidden in the ceiling. The installation position can be easily changed without dismantling the ceiling. After the functional area is changed, it can be easily disassembled and assembled, which has the advantage of convenient construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention is described in detail below in conjunction with the accompanying drawings: The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0029] Please refer to Figures 1 to 8The embodiment of the present invention provides a movable smoke barrier vertical wall 100 for building fire protection, comprising two suspension rods 110, a reel 120 rotatably connected between the two suspension rods 110, a fireproof cloth 130 rolled up on the reel 120, a gravity rod 140 parallel to the reel 120 connected to the lower end of the fireproof cloth 130, one of the suspension rods 110 is provided with a control box 150, the control box 150 is provided with a controller 151 and a smoke sensor 152 and an electromagnetic plug 153 connected thereto, when the smoke sensor When the smoke sensor 152 does not detect a smoke signal, the controller 151 controls the electromagnetic latch 153 to be inserted into the slot 121 set on the reel 120 to lock the reel 120, and the fireproof cloth 130 remains curled on the reel 120; when the smoke sensor 152 detects a smoke signal, the controller 151 controls the electromagnetic latch 153 to be pulled out from the slot 121 of the reel 120 to unlock the reel 120, and the fireproof cloth 130 is unfolded downward from the curled state to a drooping state by the gravity of the gravity rod 140. The reel 120 is in a horizontal state. The detection end of the smoke sensor 152 is exposed to the control box 150. When the reel 120 is locked, the reel 120 cannot rotate, and when the reel 120 is unlocked, it can rotate. The controller 151 can control the electromagnetic latch 153 to extend into or out of the slot 121 provided on the reel 120 to lock or unlock the reel 120 according to the detection signal of the smoke sensor 152 .

[0030] The movable smoke barrier wall 100 for building fire protection provided by the embodiment of the present invention, when the smoke sensor 152 detects a smoke signal, the controller 151 controls the electromagnetic plug 153 to be pulled out from the slot 121 of the reel 120 to unlock the reel 120, and the gravity of the gravity rod 140 can quickly drive the reel 120 to rotate, so that the fireproof cloth 130 is unfolded downward from a curled state to a drooping state, quickly forming a smoke-proof partition, and quickly blocking smoke from entering the smoke-controlled area. Compared with the driving mechanism composed of a motor, a sprocket, and a chain that controls the rotation of the reel 120 to control the drooping of the fireproof cloth 130, it has the advantages of fast drooping speed and rapid formation of smoke-proof partitions. After the electromagnetic latch 153 loses power due to a fire in the electric wire, it can be pulled out from the slot 121 of the reel 120 to unlock the reel 120, so that the fireproof cloth 130 can be drooped, and it is not affected by the power failure caused by the fire in the electric wire, which overcomes the problem that the traditional driving mechanism cannot control the fireproof cloth 130 to droop to form a smoke-proof partition after power failure. At this time, the electromagnetic latch 153 is not controlled by the detection signal of the smoke sensor 152. During the initial installation, the electromagnetic latch 153 is inserted into the slot 121 on the reel 120 to keep the reel 120 in a locked state and the fireproof cloth 130 in a curled state. It is hoisted on the indoor roof of the building through the suspension rod 110, not hidden in the ceiling, and the installation position can be easily changed without disassembling the ceiling. After the functional area is changed, it can be easily disassembled and assembled, which has the advantage of convenient construction.

[0031] Please refer to Figures 1 to 5 In order to ensure the reliability of the reel 120 when locked, the fire-fighting movable smoke barrier 100 provided in the embodiment of the present invention has an electromagnetic latch 153 connected to the controller 151 on the other suspension rod 110, and the electromagnetic latch 153 on the other suspension rod 110 is aligned with the slot 121 provided on the reel 120 at the corresponding position. Through the structure of the electromagnetic latch 153 and the slot 121 at both ends of the reel 120, it is ensured that both ends of the reel 120 are locked and unlocked at the same time, which improves the reliability of the reel 120 when locked and improves the load on the fireproof cloth 130 in the curled state.

[0032] Please refer to Figure 7In order to control the sagging of the fireproof cloth 130 to form a smokeproof partition, the embodiment of the present invention provides a movable smoke barrier wall 100 for building fire protection, wherein the controller 151 is connected to the fire monitoring center 300. When the fire monitoring center 300 sends a fire signal, the controller 151 controls the electromagnetic plug 153 to be pulled out from the slot 121 of the reel 120 to unlock the reel 120. The electromagnetic plug 153 is unlocked by the fire signal of the fire monitoring center 300 to form a smokeproof partition by sagging the fireproof cloth 130, so as to prevent smoke from flowing into the area in advance. That is, the unlocking of the reel 120 by the electromagnetic plug 153 of the movable smoke barrier wall 100 for building fire protection is controlled by three signals, the first one is linked with the fire monitoring center 300, the second one is to control the fireproof cloth 130 by the detection signal of the smoke sensor 152, and the third one is to automatically unlock after power failure.

[0033] Please refer to Figures 7 and 8 In order to prevent the problem that the smoke sensor 152 loses power and fails due to fire caused by fire-proof wires, the movable smoke barrier 100 for building fire protection provided by the embodiment of the present invention also includes a power supply device 200 connected to the controller 151. The power supply device 200 includes a battery 210, and an acoustic-to-electric conversion device 220 connected to the battery 210 and the controller 151. The acoustic-to-electric conversion device 220 includes an acoustic energy collection device 221 and a capacitive transducer 222. The capacitive transducer 222 is a variable capacitor composed of a diaphragm 2221 and a rear plate 2222. The incident sound wave is transmitted to the diaphragm 2221 through the acoustic energy collection device 221. The vibration of the diaphragm 2221 causes the variable capacitance to change, converting the sound energy into electrical energy. Thus, the battery 210 and the controller 151 are powered by the acoustic-to-electric conversion device 220, and the power supply of the building's wires is not affected. After the wires catch fire, the smoke sensor 152 will not lose power and fail. In addition, the acoustic-to-electric conversion device 220 can charge the battery 210. In order to monitor the working status of the electric energy, the power supply device 200 may be connected with a charging indicator light 230 and a full-charge indicator light 240, and the acoustic energy conversion device 220 is connected with an acoustic wave sensing indicator light 250.
