Description

Technical Field

[0001] This invention relates to the field of fire escape device technology, and more specifically, to an escape barrier device for high-rise fires and its usage method. Background Technology

[0002] Escape barriers are devices that provide temporary refuge for trapped individuals during a fire and help them evacuate safely. Traditional escape devices rely on staircases, elevators, or external rescue, but these methods are often unsafe or inefficient in high-rise buildings. Especially during a fire, smoke and high temperatures spread rapidly, rendering staircases and elevators unusable, and external rescue becomes difficult due to the height of the floors.

[0003] Therefore, it is necessary to design an escape isolation device and its usage method for high-rise fires in order to solve the problems existing in the current technology. Summary of the Invention

[0025] Furthermore, it also includes:

[0026] The first sensor group is disposed inside the body of the barrier device;

[0027] The second sensor group is located inside the barrier chamber;

[0028] A control module is disposed inside the barrier chamber, and the control module is connected to the smoke exhaust assembly, the first sensor group, and the second sensor group; the control module includes:

[0042] When the temperature characteristic value is greater than or equal to the temperature characteristic value threshold, it is determined that the initial smoke extraction strategy should be adjusted.

[0043] When the temperature characteristic value is less than the temperature characteristic value threshold, it is determined that the initial smoke exhaust strategy will not be adjusted.

[0044] Furthermore, when calculating the smoke emission impact index based on the aforementioned personnel flow data and personnel data, the following steps are included:

[0045] The personnel flow data includes personnel movement speed and the number of the first person;

[0046] The personnel data includes the number of second-hand personnel and the average time spent by personnel.

[0047] The smoke emission impact index is calculated based on the personnel movement speed, the number of first personnel, the number of second personnel, and the average personnel stay time.

[0048] The smoke emission impact index is obtained by the following formula:

[0050] Wherein, SVI I represents the smoke emission impact index; Wi represents the i-th weight coefficient; I 1 represents the personnel movement index; I 2 represents the first number of personnel; I 3 represents the second number of personnel; and I 4 represents the personnel stay index.

[0051] Furthermore, when adjusting the initial smoke extraction strategy based on the smoke extraction impact index to obtain the final smoke extraction strategy, the following steps are included:

[0054] When the smoke exhaust impact index is less than or equal to the first smoke exhaust impact index threshold, the adjustment coefficient is determined as the first adjustment coefficient, and the initial smoke exhaust strategy is adjusted according to the first adjustment coefficient to obtain the final smoke exhaust strategy.

[0055] When the smoke emission impact index is greater than the first smoke emission impact index threshold and less than or equal to the second smoke emission impact index threshold, the adjustment coefficient is determined as the second adjustment coefficient, and the initial smoke emission strategy is adjusted according to the second adjustment coefficient to obtain the final smoke emission strategy.

[0056] When the smoke emission impact index is greater than the second smoke emission impact index threshold, the adjustment coefficient is determined to be the third adjustment coefficient, and the initial smoke emission strategy is adjusted according to the third adjustment coefficient to obtain the final smoke emission strategy.

[0057] Compared with existing technologies, the advantages of this invention are as follows: The high-rise fire isolation escape device provided by this invention fully considers the emergency situation during a fire. Its structure and function are designed to provide a safe and reliable escape route for people in high-rise buildings. Through the design of the isolation device body and the isolation chamber, the fire and smoke can be effectively confined to a specific area, thus providing a relatively safe environment for escaping personnel. Simultaneously, the smoke extraction components can promptly remove smoke from the isolation chamber, ensuring clear visibility of the escape route and reducing risks during the escape process. The configuration of emergency lighting and alarm systems ensures that even in conditions of extremely low visibility, personnel can quickly find an escape route and receive timely evacuation guidance during a fire.

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

[0069] See Figure 1 As shown in some embodiments of this application, this embodiment provides an escape isolation device for high-rise fires, including:

[0070] The barrier device body 100 is a plurality of such devices, and the plurality of barrier device bodies 100 are arranged vertically inside the building 300, and the barrier device bodies 100 are connected to the inner wall of the building 300.

[0071] The first barrier door 110 is located on the side of the barrier device body 100 away from the inner wall. The first barrier door 110 is used to prevent fire and smoke from entering the interior of the barrier device body 100 when a fire occurs.

[0072] An isolation chamber 120 is located inside the isolation device body 100. An escape pipe 160 is provided on the side of the isolation chamber 120 near the inner wall. An entrance is provided on the side of the isolation chamber 120 near the first isolation door 110.

[0073] There are two fireproof layers 130, which are located on the inner wall of the barrier chamber 120 and the outer wall of the barrier chamber 120, respectively.

[0074] The second barrier door 140 is embedded inside the entrance and is used to prevent fire and smoke from entering the interior of the barrier room 120 in the event of a fire.

[0075] The smoke exhaust assembly includes a first smoke exhaust assembly 151 and a second smoke exhaust assembly 152. The first smoke exhaust assembly 151 is disposed on the top of the barrier device body 100 near the inner wall; the second smoke exhaust assembly 152 is disposed on the top of the barrier chamber 120 near the inner wall.

[0076] Emergency lighting is installed in the inner ceiling wall of the isolation room 120;

[0077] There are several escape device bodies 200, and several escape device bodies 200 are arranged vertically on the outside of the building 300. The escape device bodies 200 are connected to the outer wall of the building 300. The escape pipe 160 extends out of the barrier device body 100 and is connected to the escape device body 200. Each escape device body 200 is connected to a corresponding barrier device body 100.

[0078] The escape component is located between the two escape device bodies 200;

[0079] An alarm system, installed inside the building 300, is used to issue alarms and guide personnel to evacuate.

[0080] In this embodiment, the first barrier door 110 and the second barrier door 140 are made of high-temperature resistant composite materials, and their surfaces are coated with fire-retardant paint to ensure that the structure can maintain its integrity and barrier performance in high-temperature environments.

[0081] In this embodiment, the fireproof layer 130 is made of a heat-insulating material with excellent fire resistance, such as asbestos board or ceramic fiber board, which can effectively insulate against high temperatures and protect the safety of the internal environment of the barrier chamber 120.

[0082] In this embodiment, the emergency lighting uses LED lights as the light source, which features low power consumption and long lifespan, and can provide stable lighting in emergency situations to ensure that the escape route is clearly visible.

[0083] In this embodiment, the alarm system includes a smoke detector and an audible alarm. The smoke detector detects smoke generated by a fire, and when the detected smoke reaches a certain concentration, it triggers the audible and visual alarm to sound an alarm. The audible and visual alarm is designed with a high decibel output to ensure that it can be clearly heard by people even in a noisy fire scene.

[0084] As can be seen, the high-rise fire isolation escape device provided in this embodiment fully considers the emergency situation during a fire. Its structure and function are designed to provide a safe and reliable escape route for people in high-rise buildings. Through the installation of the isolation device body 100 and the isolation chamber 120, the fire and smoke can be effectively confined to a specific area, thus providing a relatively safe environment for escaping personnel. Simultaneously, the smoke extraction components can promptly remove smoke from the isolation chamber 120, ensuring clear visibility of the escape route and reducing risks during the escape process. The configuration of emergency lighting and an alarm system ensures that even in conditions of extremely low visibility, personnel can quickly find an escape route and receive timely evacuation guidance during a fire. The design of escape components, such as the escape ladder 211 and escape handle 212, provides multiple escape methods, increasing the flexibility and safety of escape. The control module enables the isolation escape device to automatically adjust its smoke extraction strategy based on real-time smoke concentration and temperature data, further improving escape efficiency and safety. Through the coordinated work of the data acquisition unit, judgment unit, processing unit, and adjustment unit, the device can intelligently respond to the complex changes at the fire scene and provide more accurate escape guidance for personnel.

[0085] Specifically, the first smoke exhaust assembly 151 includes:

[0086] The first exhaust fan has several of them, and the several first exhaust fans are evenly arranged horizontally on the top of the barrier device body 100 on the side close to the inner wall.

[0087] The first smoke exhaust duct is connected at one end to the smoke exhaust end of the first smoke exhaust fan, and the other end of the first smoke exhaust duct extends outside the building 300 meters.

[0088] Specifically, the second smoke exhaust assembly 152 includes:

[0089] The second smoke exhaust fan has several of them, and the several second smoke exhaust fans are evenly arranged horizontally on the top of the side of the barrier chamber 120 near the inner wall.

[0090] The second smoke exhaust duct is connected at one end to the exhaust end of the second smoke exhaust fan, and the other end of the second smoke exhaust duct extends out of the building 300 through the barrier device body 100.

[0091] Understandably, both the first and second smoke exhaust fans are made of high-temperature and corrosion-resistant materials to ensure stable operation even in high-temperature fire conditions. Each smoke exhaust fan is equipped with an independent control system that automatically adjusts its speed based on the smoke concentration and temperature at the fire scene to achieve optimal smoke extraction. The smoke exhaust ducts are made of high-temperature resistant materials, capable of withstanding extreme temperatures without deformation, ensuring unobstructed smoke extraction.

[0092] Specifically, the escape components include:

[0093] Escape ladder 211 is vertically inclined between the two escape device bodies 200, with the high end of escape ladder 211 close to the outer wall and the low end of escape ladder 211 far away from the outer wall.

[0094] There are several escape handles 212, and several escape handles 212 are evenly arranged on both sides of the escape ladder 211.

[0095] Understandably, each step of the escape ladder 211 is equipped with an anti-slip design to ensure the safety of personnel during escape. The escape handle 212 is made of an easy-to-grip shape and material, so that even in an emergency, personnel can quickly and steadily grab the handle and escape safely.

[0096] Specifically, it also includes:

[0097] The first sensor group is located inside the barrier device body 100;

[0098] The second sensor group is located inside the isolation chamber 120;

[0099] The control module is located inside the isolation chamber 120 and is connected to the smoke exhaust assembly, the first sensor group, and the second sensor group. The control module includes:

[0100] The acquisition unit is configured to acquire internal smoke concentration data of the barrier device body 100, which is recorded as the first smoke concentration, and acquire internal smoke concentration data of the barrier chamber 120, which is recorded as the second smoke concentration; and determine the initial smoke exhaust strategy based on the first smoke concentration and the second smoke concentration.

[0101] The judgment unit is configured to collect temperature data of the barrier device body 100 and determine whether to adjust the initial smoke exhaust strategy based on the temperature data.

[0102] The processing unit is configured to collect personnel flow data inside the barrier device body 100 and personnel data inside the barrier chamber 120 when it is determined that the initial smoke exhaust strategy should be adjusted, and to calculate the smoke exhaust impact index based on the personnel flow data and personnel data.

[0103] The adjustment unit is configured to adjust the initial smoke extraction strategy based on the smoke extraction impact index to obtain the final smoke extraction strategy.

[0104] Understandably, the intelligent smoke extraction strategy adjustment function of the control module enables the escape device to automatically adjust its smoke extraction strategy based on real-time smoke concentration and temperature data, further improving escape efficiency and safety. Through the coordinated work of the data acquisition unit, judgment unit, processing unit, and adjustment unit, the device can intelligently respond to complex changes in the fire scene, providing personnel with more accurate escape guidance.

[0105] Specifically, when determining the initial smoke extraction strategy based on the first smoke concentration and the second smoke concentration, it includes:

[0106] The first smoke concentration is compared with the first smoke concentration threshold, and the second smoke concentration is compared with the second smoke concentration threshold. The initial smoke extraction strategy is determined based on the comparison results.

[0107] When the first smoke concentration is less than or equal to the first smoke concentration threshold and the second smoke concentration is less than or equal to the second smoke concentration threshold, the initial smoke extraction strategy is determined to be the first smoke extraction strategy.

[0108] When the first smoke concentration is less than or equal to the first smoke concentration threshold, and the second smoke concentration is greater than the second smoke concentration threshold, the initial smoke extraction strategy is determined to be the second smoke extraction strategy.

[0109] When the first smoke concentration is greater than the first smoke concentration threshold and the second smoke concentration is greater than the second smoke concentration threshold, the initial smoke extraction strategy is determined to be the third smoke extraction strategy.

[0110] When the first smoke concentration is greater than the first smoke concentration threshold and the second smoke concentration is less than or equal to the second smoke concentration threshold, the initial smoke extraction strategy is determined to be the fourth smoke extraction strategy.

[0111] In this embodiment, the first smoke concentration threshold and the second smoke concentration threshold are preset based on the actual conditions and safety standards of building 300. These thresholds take into account the rate of smoke diffusion and the degree of harm to the human body during a fire, ensuring that the smoke extraction strategy can be activated in time before the smoke concentration reaches a dangerous level, thereby protecting personnel safety.

[0112] In this embodiment, the first smoke extraction strategy involves activating A1 first smoke extraction fans and B1 second smoke extraction fans; the second smoke extraction strategy involves activating A2 first smoke extraction fans and B2 second smoke extraction fans; the third smoke extraction strategy involves activating A3 first smoke extraction fans and B3 second smoke extraction fans; and the fourth smoke extraction strategy involves activating A4 first smoke extraction fans and B4 second smoke extraction fans. Here, A1, A2, A3, A4 and B1, B2, B3, B4 represent the number of smoke extraction fans activated under different smoke extraction strategies, and these numbers are dynamically adjusted based on real-time monitored smoke concentration and temperature data. This method ensures that in the event of a fire, the escape barrier can respond quickly according to the actual situation, effectively controlling the spread of smoke and providing a relatively safe escape environment for personnel.

[0113] Specifically, when determining whether to adjust the initial smoke extraction strategy based on temperature data, the following should be included:

[0114] Temperature feature values ​​are obtained by extracting features from the temperature data.

[0115] The temperature characteristic value is compared with the temperature characteristic value threshold, and the initial smoke exhaust strategy is adjusted based on the comparison result.

[0116] When the temperature characteristic value is greater than or equal to the temperature characteristic value threshold, it is determined that the initial smoke exhaust strategy should be adjusted.

[0117] When the temperature characteristic value is less than the temperature characteristic value threshold, it is determined that the initial smoke exhaust strategy will not be adjusted.

[0118] Understandably, during a fire, a rise in temperature often foreshadows an intensification of the fire; therefore, timely adjustments to the smoke extraction strategy are crucial. The judgment unit in the control module monitors temperature changes within the barrier device body 100 in real time. Once the temperature exceeds a preset temperature characteristic threshold, it means that the smoke extraction strategy needs to be adjusted to cope with changes in the fire intensity.

[0119] Specifically, when calculating the smoke emission impact index based on personnel flow data and personnel data, the following are included:

[0120] Personnel flow data includes personnel movement speed and the number of first persons;

[0121] Personnel data includes the number of second-hand personnel and the average time spent by personnel;

[0122] The smoke emission impact index is calculated based on personnel movement speed, number of first personnel, number of second personnel, and average personnel dwell time.

[0123] The smoke emission impact index is obtained by the following formula:

[0124]

[0125] Wherein, SVI I represents the smoke emission impact index; Wi represents the i-th weight coefficient; I 1 represents the personnel movement index; I 2 represents the first number of personnel; I 3 represents the second number of personnel; and I 4 represents the personnel stay index.

[0126] Understandably, the weighting coefficient Wi is set based on an assessment of the impact of different factors, ensuring that factors with a greater impact on escape efficiency and safety receive more attention during the calculation process. The personnel movement index (I1) reflects the movement speed of escaping personnel. Rapid movement means more efficient smoke extraction is needed to ensure clear escape routes. The personnel movement index is calculated as I1 = Vm / Tm, where Vm represents the personnel movement speed and Tm represents the escape time. The personnel dwelling index (I4) is calculated using I4 = N / Tp, where N represents the number of people in the isolation room 120 and Tp represents the average dwelling time. This calculation ensures that the smoke extraction strategy adjustment fully considers the actual escape situation of personnel, thereby optimizing the smoke extraction effect and ensuring unobstructed escape routes. Finally, the control module dynamically adjusts the initial smoke extraction strategy based on the smoke extraction impact index to adapt to real-time changes at the fire scene, ensuring that personnel can safely and quickly evacuate the danger zone. The first number of personnel (I 2) and the second number of personnel (I 3) represent the personnel density in the barrier device body 100 and the barrier chamber 120, respectively. Higher density may require stronger smoke extraction capabilities to maintain air circulation.

[0127] Specifically, when adjusting the initial smoke extraction strategy based on the smoke extraction impact index to obtain the final smoke extraction strategy, the following steps are taken:

[0128] Set adjustment coefficients, and adjust the initial smoke extraction strategy according to the adjustment coefficients; wherein, the adjustment coefficients include a first adjustment coefficient, a second adjustment coefficient, and a third adjustment coefficient;

[0129] The smoke emission impact index is compared with the first smoke emission impact index threshold and the second smoke emission impact index threshold, and the adjustment coefficient is determined based on the comparison result; wherein, the first smoke emission impact index threshold is less than the second smoke emission impact index threshold.

[0130] When the smoke emission impact index is less than or equal to the first smoke emission impact index threshold, the adjustment coefficient is determined as the first adjustment coefficient, and the initial smoke emission strategy is adjusted according to the first adjustment coefficient to obtain the final smoke emission strategy.

[0131] When the smoke emission impact index is greater than the first smoke emission impact index threshold and less than or equal to the second smoke emission impact index threshold, the adjustment coefficient is determined as the second adjustment coefficient, and the initial smoke emission strategy is adjusted according to the second adjustment coefficient to obtain the final smoke emission strategy.

[0132] When the smoke emission impact index is greater than the second smoke emission impact index threshold, the adjustment coefficient is determined as the third adjustment coefficient, and the initial smoke emission strategy is adjusted according to the third adjustment coefficient to obtain the final smoke emission strategy.

[0133] Understandably, the adjustment coefficient setting mechanism of the control module is designed to ensure that the smoke extraction strategy can be flexibly adjusted according to actual conditions to adapt to the needs of different fire scenarios. When the smoke extraction impact index is low, it indicates that the current smoke extraction strategy is sufficient to cope with the situation on site, so only minor adjustments are needed, i.e., the first adjustment coefficient is used. When the smoke extraction impact index is at a medium level, it indicates that the smoke extraction strategy needs to be strengthened to a certain extent, at which point the second adjustment coefficient is used. When the smoke extraction impact index is high, it indicates that the current smoke extraction strategy cannot meet the needs on site, and a significant adjustment is needed to enhance the smoke extraction effect, at which point the third adjustment coefficient is used. Through this tiered adjustment mechanism, the control module can ensure timely and effective adjustment of the smoke extraction strategy, thereby maximizing the safe evacuation of personnel. The final determination of the smoke extraction strategy is based on the analysis of real-time data and a comprehensive judgment of the fire scene situation, ensuring that the escape isolation device can provide the optimal escape plan in the event of a fire.

[0134] See Figure 2 As shown in some embodiments of this application, this embodiment provides a method for using an escape isolation device for high-rise fires, including the following steps:

[0135] S100: Collect the internal smoke concentration data of the barrier device body and record it as the first smoke concentration; collect the internal smoke concentration data of the barrier chamber and record it as the second smoke concentration; determine the initial smoke exhaust strategy based on the first smoke concentration and the second smoke concentration;

[0136] S200: Collect temperature data of the barrier device body, and determine whether to adjust the initial smoke extraction strategy based on the temperature data;

[0137] S300: When it is determined that the initial smoke exhaust strategy needs to be adjusted, collect personnel flow data inside the barrier device body and personnel data inside the barrier chamber, and calculate the smoke exhaust impact index based on the personnel flow data and personnel data;

[0138] S400: Adjust the initial smoke extraction strategy based on the smoke extraction impact index to obtain the final smoke extraction strategy.

[0139] Understandably, through the steps described above, the escape isolation device can automatically perform a series of intelligent operations in the event of a fire, thereby providing people with a safe and effective escape route. The entire process requires no human intervention, greatly improving escape efficiency and safety.
