[0069] See also Figure 1 As shown, in some embodiments of the present application, this embodiment provides a barrier escape device for high-rise fire, including:

[0070] The barrier device body 100 has a plurality of them. The plurality of barrier device bodies 100 are arranged inside the building 300 along the vertical direction, and the barrier device body 100 is connected to the inner wall of the building 300;

[0071] A first barrier door 110 is provided on a 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;

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

[0074] The second barrier door 140 is embedded in the entrance of the chamber. The second barrier door 140 is used to prevent fire and smoke from entering the barrier chamber 120 when a fire occurs;

[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 arranged on the top of the side of the barrier device body 100 close to the inner wall; the second smoke exhaust assembly 152 is arranged on the top of the side of the barrier chamber 120 close to the inner wall;

[0076] An emergency lighting lamp is embedded in the inner top wall of the isolation chamber 120;

[0077] There are a plurality of escape device bodies 200, which are arranged outside the building 300 in the vertical direction, and 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, and each escape device body 200 is correspondingly connected to a barrier device body 100;

[0078] An escape assembly is located between the two escape device bodies 200;

[0079] An alarm system is installed inside the building 300, and the alarm system is used to sound an alarm and guide people 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 the surfaces thereof are coated with fire retardant paint to ensure that the structural integrity and barrier properties can be maintained in a high temperature environment.

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

[0082] In this embodiment, the emergency lighting uses LED lamps as light sources, which have the characteristics of low power consumption and long life, 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 a sound alarm. The smoke detector is used to detect smoke generated by a fire. When the smoke reaches a certain concentration, the sound and light alarm is triggered to sound an alarm. The sound and light alarm is designed to have a high decibel output to ensure that it can be clearly heard by personnel even at a noisy fire scene.

[0084] It can be seen that the barrier escape device for high-rise fires provided in this embodiment fully considers the emergency situation when a fire occurs, and its structure and function are set to provide a safe and reliable escape route for people in high-rise buildings. Through the setting of the barrier device body 100 and the barrier chamber 120, the fire and smoke can be effectively confined to a specific area, thereby providing a relatively safe environment for escaping people. At the same time, the setting of the smoke exhaust component can timely remove the smoke in the barrier chamber 120, ensure the clear visibility of the escape passage, and reduce the risk during the escape process. The configuration of the emergency lighting and alarm system ensures that when a fire occurs, even in extremely low visibility, people can quickly find the escape route and receive timely evacuation guidance. The design of the escape component, such as the escape ladder 211 and the escape handle 212, provides people with a variety of escape methods, increasing the flexibility and safety of escape. The control module enables the barrier escape device to automatically adjust the smoke exhaust strategy according to real-time smoke concentration and temperature data, further improving the escape efficiency and safety. Through the coordinated work of the collection unit, judgment unit, processing unit and adjustment unit, the device can intelligently respond to the complex changes at the fire scene and provide personnel with more accurate escape guidance.

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

[0086] There are a plurality of first smoke exhaust fans, and the plurality of first smoke exhaust fans are evenly arranged in the horizontal direction at the top of one side of the barrier device body 100 close to the inner wall;

[0087] One end of the first smoke exhaust duct is connected to the smoke exhaust end of the first smoke exhaust fan, and the other end of the first smoke exhaust duct extends out of the building 300 .

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

[0089] There are a plurality of second smoke exhaust fans, and the plurality of second smoke exhaust fans are evenly arranged in the horizontal direction at the top of the barrier chamber 120 on one side close to the inner wall;

[0090] One end of the second smoke exhaust duct is connected to the smoke exhaust end of the second smoke exhaust fan, and the other end of the second smoke exhaust duct passes through the barrier device body 100 and extends to the outside of the building 300 .

[0091] It is understandable that the first smoke exhaust fan and the second smoke exhaust fan are made of high temperature resistant and corrosion resistant materials to ensure stable operation under high temperature environment of fire. Each smoke exhaust fan is equipped with an independent control system, which can automatically adjust the speed according to the smoke concentration and temperature at the fire scene to achieve the best smoke exhaust effect. The smoke exhaust duct is made of high temperature resistant material, which can withstand extreme temperatures without deformation, ensuring the unobstructed smoke exhaust channel.

[0092] Specifically, the escape components include:

[0093] The escape ladder 211 is tilted in the vertical direction and arranged between the two escape device bodies 200, and the high end of the escape ladder 211 is close to the outer wall, and the low end of the escape ladder 211 is far away from the outer wall;

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

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

[0096] Specifically, it also includes:

[0097] A first sensor group is disposed inside the barrier device body 100;

[0098] A second sensor group is disposed inside the barrier chamber 120;

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

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

[0101] A judgment unit, configured to collect temperature data of the barrier device body 100, and judge whether to adjust the initial smoke exhaust strategy according to 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 is to be adjusted, and calculate the smoke exhaust impact index based on the personnel flow data and the personnel data;

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

[0104] It is understandable that the intelligent smoke exhaust strategy adjustment function of the control module enables the barrier escape device to automatically adjust the smoke exhaust strategy according to the real-time smoke concentration and temperature data, further improving the escape efficiency and safety. Through the collaborative work of the acquisition unit, judgment unit, processing unit and adjustment unit, the device can intelligently respond to the complex changes of the fire scene and provide more accurate escape guidance for personnel.

[0105] Specifically, when determining the initial smoke exhaust strategy based on the first smoke density and the second smoke density, 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, and an initial smoke exhaust strategy is determined according to 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, determining that the initial smoke exhaust strategy is the first smoke exhaust 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 exhaust strategy is determined to be the second smoke exhaust 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, determining that the initial smoke exhaust strategy is the third smoke exhaust strategy;

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

[0111] In this embodiment, the first smoke concentration threshold and the second smoke concentration threshold are preset according to the actual situation and safety standards of the building 300. The setting of these thresholds takes into account the diffusion speed of smoke and the degree of harm to the human body when a fire occurs, so as to ensure that the smoke exhaust strategy can be activated in time before the smoke concentration reaches a dangerous level, thereby ensuring the safety of personnel.

[0112] In this embodiment, the first smoke exhaust strategy is to open the number of first smoke exhaust fans A1 and the number of second smoke exhaust fans B1; the second smoke exhaust strategy is to open the number of first smoke exhaust fans A2 and the number of second smoke exhaust fans B2; the third smoke exhaust strategy is to open the number of first smoke exhaust fans A3 and the number of second smoke exhaust fans B3; the fourth smoke exhaust strategy is to open the number of first smoke exhaust fans A4 and the number of second smoke exhaust fans B4. Among them, A1, A2, A3, A4 and B1, B2, B3, B4 respectively represent the number of smoke exhaust fans opened under different smoke exhaust strategies, and these numbers are dynamically adjusted according to the real-time monitored smoke concentration and temperature data. In this way, it can be ensured that when a fire occurs, the barrier escape device can respond quickly according to the actual situation, effectively control the spread of smoke, and provide a relatively safe escape environment for personnel.

[0113] Specifically, when judging whether to adjust the initial smoke exhaust strategy based on temperature data, it includes:

[0114] Extract features from the temperature data to obtain temperature characteristic values;

[0115] Compare the temperature characteristic value with the temperature characteristic value threshold, and determine whether to adjust the initial smoke exhaust strategy according to 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 is to 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 is not adjusted.

[0118] It is understandable that when a fire occurs, the increase in temperature often indicates that the fire is getting worse, so it is very important to adjust the smoke exhaust strategy in a timely manner. The judgment unit in the control module will monitor the temperature change in the barrier device body 100 in real time. Once the temperature exceeds the preset temperature characteristic value threshold, it means that the smoke exhaust strategy needs to be adjusted to cope with the change in the fire.

[0119] Specifically, when calculating the smoke exhaust impact index based on personnel flow data and personnel data, it includes:

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

[0121] Personnel data include the number of second personnel and the average length of stay of personnel;

[0122] The smoke exhaust 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;

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

[0124]

[0125] Among them, SVI I represents the smoke exhaust 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; I 4 represents the personnel stay index.

[0126] It is understandable that the setting of the weight coefficient Wi is based on the evaluation of the degree of influence of different factors, ensuring that in the calculation process, factors that have a greater impact on escape efficiency and safety can be given more attention. The personnel movement index (I1) reflects the movement speed of the escape personnel. Fast movement means that more efficient smoke exhaust is required to ensure the clarity of the escape route. The calculation process of the personnel movement index is I1=Vm / Tm, where Vm represents the movement speed of the personnel and Tm represents the escape time. The personnel stay index (I4) is calculated by I4=N / Tp, where N represents the number of personnel in the barrier chamber 120 and Tp represents the average personnel stay time. Through such calculations, it can be ensured that the adjustment of the smoke exhaust strategy can fully take into account the actual escape situation of the personnel, thereby optimizing the smoke exhaust effect and ensuring the smooth escape path. Finally, the control module dynamically adjusts the initial smoke exhaust strategy according to the smoke exhaust impact index to adapt to the real-time changes at the fire scene and ensure that personnel can evacuate the dangerous area safely and quickly. The first number of people (I 2) and the second number of people (I 3) represent the density of people in the barrier device body 100 and the barrier chamber 120, respectively. A high density may require a stronger smoke exhaust capability to maintain air circulation.

[0127] Specifically, the initial smoke exhaust strategy is adjusted based on the smoke exhaust impact index to obtain the final smoke exhaust strategy, including:

[0128] Setting an adjustment coefficient, and adjusting the initial smoke exhaust strategy according to the adjustment coefficient; wherein the adjustment coefficient includes a first adjustment coefficient, a second adjustment coefficient, and a third adjustment coefficient;

[0129] The smoke exhaust impact index is compared with the first smoke exhaust impact index threshold and the second smoke exhaust impact index threshold, and the adjustment coefficient is determined according to the comparison result; wherein the first smoke exhaust impact index threshold is less than the second smoke exhaust impact index threshold;

[0130] When the smoke exhaust impact index is less than or equal to the first smoke exhaust impact index threshold, determining the adjustment coefficient as the first adjustment coefficient, and adjusting the initial smoke exhaust strategy according to the first adjustment coefficient to obtain a final smoke exhaust strategy;

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

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

[0133] It is understandable that the adjustment coefficient setting mechanism of the control module is to ensure that the smoke exhaust strategy can be flexibly adjusted according to the actual situation to meet the needs of different fire scenarios. When the smoke exhaust impact index is low, it indicates that the current smoke exhaust strategy is sufficient to cope with the on-site situation, so only fine-tuning is required, that is, the first adjustment coefficient is adopted. When the smoke exhaust impact index is at a medium level, it indicates that the smoke exhaust strategy needs to be strengthened to a certain extent. At this time, the second adjustment coefficient is adopted. When the smoke exhaust impact index is high, it indicates that the current smoke exhaust strategy cannot meet the on-site needs and needs to be adjusted significantly to enhance the smoke exhaust effect. At this time, the third adjustment coefficient is adopted. Through such a hierarchical adjustment mechanism, the control module can ensure the timely and effective adjustment of the smoke exhaust strategy, thereby maximizing the safe evacuation of personnel. The final determination of the smoke exhaust strategy is based on the analysis of real-time data and the comprehensive judgment of the fire scene situation, ensuring that the barrier escape device can provide the most optimized escape plan when a fire occurs.
