Abstract
Description
Technical Field
[0001] This invention relates to the field of building fire protection technology, and in particular to a fire isolation device and its usage method for high-rise buildings. Background Technology
[0002] High-rise buildings are characterized by their height, long vertical space, dense population, and complex evacuation routes. When a fire breaks out, the fire spreads rapidly and the smoke spreads over a wide area. The impact of thermal convection is particularly severe in high-rise buildings, where high-temperature gases and flames continuously move upwards. After the window glass breaks, it can ignite the room on the floor above, causing the fire to spread rapidly vertically, affecting the lives and property of more people and posing a great challenge to personnel evacuation and fire rescue.
[0003] As a key component of the fire protection system of high-rise buildings, fire isolation devices play a crucial role in quickly forming an effective barrier in the early stages of a fire, blocking the spread of fire and smoke, buying precious time for evacuation, and reducing property damage caused by the expansion of the fire.
[0004] In existing technologies, most fire protection measures are laid in the corridors and few external protections are designed, which causes flames to spread from the outside of the building through the windows. Therefore, a fire protection device for high-rise buildings is needed to meet people's needs.
[0005] Existing fire isolation devices have the following shortcomings:
[0006] 1. Poor sealing performance of partitions: Traditional partition devices are mostly single-layer curtain structures, and gaps are likely to exist between the curtain and the installation frame. High-temperature smoke generated by fire can easily penetrate through the gaps, making it impossible to achieve a complete partition effect and difficult to effectively prevent the spread of fire.
[0007] 2. Limited fireproof and heat insulation effect: Existing devices mostly rely on the flame-retardant properties of a single fireproof curtain, lacking active filling and cooling structures. They are not strong enough to resist the high temperatures generated by fire and are prone to failure after being baked by high temperatures for a long time, thus failing to play a continuous role in insulation. Summary of the Invention
[0008] To overcome the above deficiencies, the present invention provides a fire isolation device and its usage method for high-rise buildings, thereby solving the aforementioned problems.
[0009] To achieve the above objectives, the present invention adopts the following technical solution: a fire isolation device for high-rise buildings, comprising an outer partition layer, a storage compartment, and a fixing frame.
[0010] Furthermore: the storage compartment includes a storage compartment body, the outer layer of the partition includes a first fireproof curtain, a second fireproof curtain and a U-shaped connecting block, the outer layer of the partition forms a cavity, the storage compartment also includes a storage part, the storage part includes a first roller and a second roller, the first roller and the second roller are rotatably mounted on the storage compartment body through bearings, the first fireproof curtain and the second fireproof curtain are respectively rolled up and stored on the first roller and the second roller;
[0011] It also includes a filling component, which includes a material hopper and a water pipe. The water pipe's inlet is connected to a tap water pipe. The material hopper stores fire-fighting absorbent granules. The material hopper includes a discharge pipe. The outlets of the discharge pipe and the water pipe are both located between the first and second reels, aligned with the cavity of the outer layer of the partition.
[0012] Furthermore, the material silo also includes a disturbance shaft, a feed inlet, a motor, and an air pump. The motor is installed on the side wall of the material silo, and the disturbance shaft is connected to the motor. The disturbance shaft is provided with multiple radially diverging rods. The feed inlet is provided on the side wall of the material silo, and the air pump is installed on the outer side wall of the material silo. The air pump includes an air outlet pipe and an air inlet pipe, and the air outlet of the air outlet pipe is located inside the material silo.
[0013] Furthermore: the discharge pipe is divided into a first discharge pipe and a second discharge pipe.
[0014] Furthermore: the water inlet of the water pipe is a single pipe, and the water pipe splits into three outlet pipes when it exits the water. The water outlet of the water pipe is divided into a first outlet, a second outlet, and a third outlet, and the water outlet of the water pipe is arranged alternately with the first outlet pipe and the second outlet pipe.
[0015] Furthermore: the water pipe is equipped with a water pressure detection device, and the water inlet pipe of the water pipe is equipped with a solenoid valve.
[0016] Furthermore: the fixed frame is fixed to the bottom of the storage compartment, the fixed frame includes a side rail frame and a frame bottom groove, the cross-section of the side rail frame is an inward-opening groove, and the cross-section of the frame bottom groove is an upward-opening groove.
[0017] Furthermore, the storage compartment also includes a transmission part, which includes a driving part, a driven wheel two, a second transmission chain, a driven wheel three, and a third transmission chain. The driven wheel two is keyed and mounted on a first spool, and the driven wheel three is keyed and mounted on a second spool.
[0018] Furthermore: the active part includes an active fixing plate, an active wheel, a driven wheel one, a first transmission chain, a support frame, and a motor. The active fixing plate is fixed to the storage compartment body of the storage compartment. The motor is fixed to the active fixing plate. The support frame is fixed to the active fixing plate and supports the motor. The motor shaft of the motor is connected to the active wheel via a key. The driven wheel one is rotatably connected to the active fixing plate. The active wheel and the driven wheel one are chain-driven by the first transmission chain. The active wheel and the driven wheel two are chain-driven by the second transmission chain. The driven wheel one and the driven wheel three are chain-driven by the third transmission chain.
[0019] A method for using a fire isolation device in a high-rise building, characterized by comprising the following steps:
[0020] S1. When a fire occurs, the activation device starts the transmission part of the storage compartment, and the motor drives the drive wheel to rotate.
[0021] S2. The driving wheel drives the driven wheel one to rotate through the first transmission chain, and at the same time drives the driven wheel two to rotate through the second transmission chain. The driven wheel one drives the driven wheel three to rotate through the third transmission chain.
[0022] S3, driven wheel two and driven wheel three drive the first roller and the second roller to rotate synchronously, lowering the first fireproof curtain and the second fireproof curtain. The first fireproof curtain, the second fireproof curtain and the U-shaped connecting block descend along the direction defined by the fixed frame to form the outer layer of the partition;
[0023] S4. The air pump and the motor on the side wall of the material silo start. The motor drives the disturbance shaft to rotate, disturbing the fire-fighting water-absorbing particles in the material silo. The fire-fighting water-absorbing particles enter the cavity of the outer layer of the partition through the discharge pipe along with the airflow generated by the air pump.
[0024] S5. When the solenoid valve is opened, the water pipe simultaneously delivers water into the cavity. The water mixes with the fire-fighting water-absorbing particles and expands to form the inner layer of the partition.
[0025] S6. When the inner layer of the partition reaches the outlet of the water pipe, the water pressure detection device detects that the water pressure in the water pipe has increased, and the solenoid valve closes, stopping the water from entering the water pipe.
[0026] The present invention has the following beneficial effects:
[0027] 1. Significantly improved partition sealing: The invention uses a first fireproof curtain, a second fireproof curtain, and a U-shaped connecting block to form a double-layer partition outer layer, creating a closed cavity; the fire-absorbing particles injected by the filling component absorb water and expand, which will squeeze the double-layer curtain outward, so that the curtain fits tightly with the grooved fixed frame (side rail frame, frame bottom groove), completely eliminating the gap problem of traditional partition devices and effectively blocking the penetration and spread of fire smoke and fire.
[0028] 2. Enhanced fire resistance and heat insulation performance: Through the composite structure of "double-layer fireproof curtain + soft rubber expansion inner layer", the outer curtain plays a basic flame-retardant role, while the inner expanded soft rubber partition layer has both efficient heat insulation and cooling functions. The combination of moisture and fire-fighting water-absorbing particles can not only absorb a large amount of heat, but also form a dense heat insulation barrier, avoiding the problem of traditional single curtains being easily damaged by high temperature baking, and continuously ensuring the partition effect.
[0029] 3. Significantly optimized filling efficiency and uniformity: The material hopper is equipped with an air pump and double-sided disturbance shafts. The rotation of the disturbance shafts can break up the fire-fighting water-absorbing particles. Combined with the airflow of the air pump, it ensures that the particles enter the cavity quickly and evenly. At the same time, the water outlet and the discharge pipe are staggered to achieve synchronous mixing of water and particles, accelerate the water absorption and expansion rate, and quickly form a stable partition layer.
[0030] 4. High efficiency and reliable transmission and storage response: The transmission part adopts the design of "motor + multi-stage chain drive". The drive wheel drives the two rollers to rotate synchronously through the chain, realizing the synchronous lifting and lowering of the double-layer fireproof curtain, which greatly improves the device's start-up response efficiency and meets the needs of rapid isolation in the early stage of a fire.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0045] Example 1
[0046] Reference Figure 1-11 The present invention provides a fire isolation device for high-rise buildings, including an outer partition layer, a filling component and a storage compartment 1.
[0047] The outer layer of the partition includes a first fireproof curtain 11, a second fireproof curtain 12, and a U-shaped connecting block 17. The bottoms of the first fireproof curtain 11 and the second fireproof curtain 12 are both fixed to the U-shaped connecting block 17 to form the outer layer of the partition.
[0048] The filling component includes a material bin 2 and a water pipe 13. After the outer layer of the partition is lowered, the first fireproof curtain 11, the second fireproof curtain 12 and the U-shaped connecting block 17 form a cavity. At this time, the filling component will fill the cavity with fire-fighting water-absorbing particles and water respectively. The fire-fighting water-absorbing particles will absorb water and expand after contact with water, forming a soft rubber inner layer of the partition.
[0049] The storage compartment 1 is located at the top of the device and is used to store the first fireproof curtain 11 and the second fireproof curtain 12. The bottom of the storage compartment 1 has an opening for the passage of the first fireproof curtain 11 and the second fireproof curtain 12. The fixing frame 3 is fixed to the bottom of the storage compartment 1 and corresponds to the opening position at the bottom of the storage compartment 1. The fixing frame 3 is divided into side rail frames 31 on both sides and frame bottom groove 32 at the bottom. The cross section of both is groove-shaped and is used to fix and guide the outer layer of the partition.
[0050] When the device is not activated, both the first fireproof curtain 11 and the second fireproof curtain 12 are stored in the storage compartment 1 at the top of the device. The storage compartment 1 includes a storage part and a transmission part.
[0051] The storage compartment 1 includes a first roller 111 and a second roller 121. The first fireproof curtain 11 is rolled up and stored on the outer arc surface of the first roller 111, and the second fireproof curtain 12 is rolled up and stored on the outer arc surface of the second roller 121. The first roller 111 and the second roller 121 are both rotatably mounted on the storage compartment body 15 at both ends. Bearings are installed between the shaft ends and the storage compartment body 15, thereby realizing the relative rotation of the first roller 111 and the second roller 121 with the storage compartment body 15. The storage compartment body 15 is divided into two halves and is fixed into a whole by mounting ears 16.
[0052] The transmission system of storage compartment 1 includes a driving part 14, a driven wheel 112, a second transmission chain 113, a driven wheel 122, and a third transmission chain 123. The driving part 14 includes a driving fixing plate 141, a driving wheel 142, a driven wheel 143, a first transmission chain 144, a support frame 145, and a motor 4. The motor 4 is fixed on the driving fixing plate 141. A support frame 145 is provided at the bottom of the motor 4 to support it. The support frame 145 is fixedly connected to the driving fixing plate 141. The driving wheel 142 is mounted on the motor shaft of the motor 4 via a key connection. The driving wheel 142 includes two wheel bodies with different diameters. The wheel body structure of the driven wheel 143 is the same as that of the driving wheel 142. The driven wheel 143 rotates... The drive wheel 142 is connected to the active fixed plate 141. The drive wheel 142 and the driven wheel 143 are driven by the first transmission chain 144. The driven wheel 112 is connected to the first roller 111 by a key. The driven wheel 112 and the drive wheel 142 are driven by the second transmission chain 113. The driven wheel 122 is connected to the second roller 121 by a key. The driven wheel 122 and the driven wheel 143 are driven by the third transmission chain 123. Through the power transmission of the transmission part, the forward and reverse rotation of the motor 4 can control the forward and reverse rotation of the first roller 111 and the second roller 121, and further control the lifting and lowering of the first fireproof curtain slat 11 and the second fireproof curtain slat 12. The storage compartment 1 is fireproofed.
[0053] The filling section includes a material silo 2, a water pipe 13, and an air pump 5. Dry fire-fighting absorbent granules are added to the material silo 2 through the feed inlet 22. The outlets of the material silo 2's discharge pipe 23 and the water pipe 13 are both located between the first reel 111 and the second reel 121. The discharge pipe 23 is divided into a first discharge pipe 231 and a second discharge pipe 232. The water pipe 13 is supplied with water through a water inlet pipe connected to a tap water supply line. A solenoid valve 6 is installed on the water inlet pipe to control the start and stop of water supply to the water pipe 13. The water pipe 13 is divided into three outlet pipes before the outlet: a first outlet 131, a second outlet 132, and a third outlet 133. A water pressure detection device is installed in the water pipe 13. The outlets of the water pipe 13 and the two discharge pipes 23 are staggered, so that the fire-fighting absorbent granules can be fully mixed with water during filling, accelerating the formation rate of the inner layer of the partition.
[0054] An air pump 5 is installed on the outside of the material silo 2. The air outlet pipe 51 of the air pump 5 is connected to the inside of the material silo 2. During filling, the air pump 5 draws air from the outside through the suction pipe 52 and outputs the gas into the material silo 2 through the air outlet pipe 51. A one-way valve is provided in the air outlet pipe 51 of the air pump 5 to prevent fire-fighting water-absorbing particles from entering the air pump 5. The air pump 5 blows the small and lightweight fire-fighting water-absorbing particles in the material silo body 24 into the cavity formed by the first fireproof curtain 11, the second fireproof curtain 12 and the U-shaped connecting block 17 through the discharge pipe 23. In order to improve the filling efficiency, motors 4 are installed on both the left and right sides of the material silo 2. The motors 4 are connected to the disturbance shaft 21. The disturbance shaft 21 is provided with multiple radially diverging rods. The motors 4 drive the disturbance shaft 21 to rotate, thereby disturbing the fire-fighting water-absorbing particles in the material silo 2, making it easier for the fire-fighting water-absorbing particles to be output into the cavity along with the airflow. The structure of the material silo 2 and the air pump 5 are both fireproofed.
[0055] Example 2
[0056] Based on Example 1, a method for using a fire isolation device in a high-rise building is as follows:
[0057] In the event of a fire, this device is activated, and the active part 14 of the storage compartment 1 starts. The motor 4 of the active part 14 begins to rotate, driving the active wheel 142 to rotate. The active wheel 142 drives the driven wheel 143 and driven wheel 112 to rotate synchronously through the first transmission chain 144 and the second transmission chain 113. The driven wheel 143 drives the driven wheel 122 to rotate synchronously through the third transmission chain 123.
[0058] Driven wheel 2 112 and driven wheel 3 122 drive the first roller 111 and the second roller 121 to rotate synchronously. The synchronous rotation of the first roller 111 and the second roller 121 lowers the first fireproof curtain 11 and the second fireproof curtain 12. The first fireproof curtain 11, the second fireproof curtain 12 and the U-shaped connecting block 17 descend synchronously along the movement direction defined by the fixed frame 3 to form the outer layer of the partition.
[0059] The air pump 5 and the motor 4 on the side wall of the material silo 2 start simultaneously. The motor 4 drives the disturbance shaft 21 to rotate, disturbing the fire-fighting water-absorbing particles in the material silo 2. The air pump 5 draws air from the outside through the air suction pipe 52 and outputs gas into the material silo 2 through the air outlet pipe 51, so that the fire-fighting water-absorbing particles enter the cavity of the outer layer of the partition along with the airflow generated by the air pump 5.
[0060] When solenoid valve 6 is opened, water is simultaneously filled into water pipe 13 while fire-fighting water-absorbing particles are being filled. The water and fire-fighting water-absorbing particles mix in the cavity of the outer layer of the partition. The fire-fighting water-absorbing particles absorb water and expand upon contact with it, forming a soft gel-like inner layer of the partition. When the inner layer of the partition reaches the outlet of water pipe 13, the water pressure in water pipe 13 increases. After the detection device detects the increase in water pressure, solenoid valve 6 closes, stopping the water intake.
[0061] The inner layer of the partition pushes the first fireproof curtain 11 and the second fireproof curtain 12 of the outer layer of the partition outward, so that the outer layer of the partition is tightly fitted with the fixed frame 3, and the inner layer of the partition blocks the smoke and high temperature generated by the fire, and cools the outer layer of the partition.
[0062] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
