Abstract
Description
Technical Field
[0001] This utility model relates to the field of building safety technology, and more specifically, to a safety escape device for high-rise buildings. Background Technology
[0002] High-rise building safety escape is a complex but crucial issue, involving knowledge of building structure, emergency plans, and personal protection. In high-rise buildings, vertical passageways (elevator shafts, stairwells) create a "chimney effect" during fires, causing the vertical spread of fire to reach 5-8 meters per second, more than three times the horizontal spread. High-temperature smoke (600-1000℃) diffuses through pipes and gaps; in fires above the sixth floor, 80% of deaths are caused by asphyxiation and poisoning (carbon monoxide concentrations exceeding 1200 ppm are fatal).
[0003] The hazards of high-rise building fires exhibit a "three-dimensional diffusion" characteristic—vertical fire spread, horizontal economic losses, and the continuation of social trauma over time.
[0004] Currently, escape devices used for high-rise building fires can only move up and down in one longitudinal direction. However, high-rise buildings often have multiple households on one floor, and the presence of fire hazard further obstructs access to the escape device. For example, a high-rise building safety escape device (application number 201920166005.X) disclosed in the prior art, consisting of a "backrest", "protective board" and "seat", can only move up and down in one longitudinal direction. Utility Model Content
[0005] (a) Technical issues
[0006] The purpose of this utility model is to address the shortcomings of existing technologies: current escape devices for high-rise building fires can only move up and down in one longitudinal direction; however, high-rise buildings often have multiple households on one floor, and the presence of fire hazards further hinders access to the escape device. Therefore, this utility model proposes a safety escape device for high-rise buildings.
[0007] (II) Technical Solution
[0008] A safety escape device for high-rise buildings includes a position adjustment component installed on the top of an escape cage, the position adjustment component comprising:
[0009] A height-traction structure is attached to the top of the escape cage via a traction rope; the height-traction structure is used to adjust the height of the escape cage via the traction rope.
[0010] Two guide sleeves are distributed at both ends of the height traction structure; the guide sleeves are fixed to the height traction structure by fixing plates.
[0011] Two guide posts correspond one-to-one with two guide sleeves; the guide posts are movably inserted into the guide sleeves, and both the outer surface of the guide posts and the inner surface of the guide sleeves are smooth; the guide posts are installed on the top of the building.
[0012] A displacement traction structure is installed on the height traction structure between two guide sleeves; the displacement traction structure is used to adjust the lateral position of the height traction structure and the escape cage.
[0013] When a fire breaks out in a high-rise building and escape is necessary, the displacement traction structure is activated. This structure, along with the height traction structure and escape cage, is then adjusted laterally using guide columns and guide sleeves to precisely position them above the escape point. The height traction structure is then activated again to lower the escape cage to the escape point. This improved mobility allows for comprehensive coverage of the building, facilitating precise subsequent rescue efforts.
[0014] In the detailed technical solution, the displacement traction structure includes:
[0015] A take-up drum is installed on a high-traction structure;
[0016] One take-up and untake-down reel is attached to one end of the take-up drum;
[0017] The second take-up reel is attached to the other end of the take-up drum.
[0018] Furthermore, the take-up and release reel one, the take-up and release reel two, and the height traction structure adopt the same structure. The height traction structure has a take-up roller installed inside, and the take-up roller is mounted on the output shaft of the motor.
[0019] Furthermore, the displacement traction structure also includes:
[0020] The first pull rope is attached to one side of the first take-up and take-down tray and inserted into the inside of the first take-up and take-down tray;
[0021] The second pull rope is attached to one side of the second take-up and take-down tray and inserted into the inside of the second take-up and take-down tray;
[0022] Both the pull rope one and pull rope two are parallel to the guide column; pull rope one and pull rope two are installed on the top of the building.
[0023] In the detailed technical solution, the escape cage includes:
[0024] Escape cage;
[0025] The door frame is installed on the front end of the escape cage.
[0026] Multiple uprights are arrayed on the door frame and the side walls around the escape cage.
[0027] Furthermore, the upright plate is made of heat-insulating and flame-retardant material.
[0028] Furthermore, the upright plate is equipped with a reinforcing plate inside, and the reinforcing plate is made of metal.
[0029] The upright plate has air guiding channels inside its main body, and the air guiding channels are distributed along the main body of the upright plate; the air guiding channels are connected to the exhaust fan, and the exhaust fan is installed on the top of the escape cage.
[0030] Multiple air outlets are provided on the upright plate outside the air guide channel, and the multiple air outlets are distributed at equal intervals along the main body of the upright plate; the air outlets are connected to the air guide channel; and all the air outlets face the outside of the escape cage.
[0031] When a fire occurs in a high-rise building and escape is necessary, the exhaust fan is activated to ventilate the air ducts in multiple vertical panels, creating a stable outward airflow within the ducts. Combined with multiple air outlets on the outside of the air ducts, this exhausts the gas, creating a protective airflow around the escape cage to disperse smoke emitted from the building due to the fire and ensure the breathing environment for those inside the escape cage. Simultaneously, the vertical panels are made of heat-insulating and flame-retardant material, which, along with the multiple air outlets, also ensures a suitable temperature environment inside the escape cage.
[0032] The positioning connection component includes:
[0033] A U-shaped locking bar is attached to the exhaust fan; the exhaust fan is equipped with a reinforced outer shell, which is fixed to the top of the escape cage; the U-shaped locking bar is integrally fixed to the reinforced outer shell.
[0034] A connecting plate is fixed to a U-shaped locking rod; the end of the connecting plate away from the U-shaped locking rod is fixed to the end of the traction rope.
[0035] (III) Beneficial Effects
[0036] Compared with existing technologies, this utility model of a high-rise building safety escape device can achieve the following:
[0037] When a fire breaks out in a high-rise building and escape is necessary, the displacement traction structure is activated. The displacement traction structure drives the height traction structure and the escape cage to make lateral adjustments through the cooperation of guide columns and guide sleeves, so as to accurately adjust the height traction structure and the escape cage above the escape point. Then, the height traction structure is activated to lower the escape cage to the escape point. This improves mobility and allows for all-round coverage of the building, so as to facilitate subsequent precise rescue.
[0038] When a fire occurs in a high-rise building and escape is necessary, the exhaust fan is activated to ventilate the air ducts in multiple vertical panels, creating a stable outward airflow within the ducts. Combined with multiple air outlets on the outside of the air ducts, this exhausts the gas, creating a protective airflow around the escape cage to disperse smoke emitted from the building due to the fire and ensure the breathing environment for those inside the escape cage. Simultaneously, the vertical panels are made of heat-insulating and flame-retardant material, which, along with the multiple air outlets, also ensures a suitable temperature environment inside the escape cage.

[0049] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the protection scope of this utility model.
[0050] In this embodiment of the utility model, such as Figures 1-3 As shown: A safety escape device for high-rise buildings includes a position adjustment component 100 installed on the top of an escape cage 300, the position adjustment component 100 comprising:
[0051] A height traction structure 150 is attached to the top of the escape cage 300 via a traction rope 160; the height traction structure 150 is used to adjust the height of the escape cage 300 via the traction rope 160.
[0052] Two guide sleeves 120 are distributed at both ends of the height traction structure 150; the guide sleeves 120 are fixed to the height traction structure 150 by a fixing plate 140.
[0053] Two guide posts 110 correspond one-to-one with two guide sleeves 120; the guide posts 110 are movably inserted into the interior of the guide sleeves 120, and the outer surface of the guide posts 110 and the inner surface of the guide sleeves 120 are both smooth; the guide posts 110 are installed on the top of the building.
[0054] A displacement traction structure 130 is installed on a height traction structure 150 between two guide sleeves 120; the displacement traction structure 130 is used to adjust the lateral position of the height traction structure 150 and the escape cage 300.
[0055] Therefore, current escape devices used in high-rise building fires can only move up and down in one vertical direction; however, high-rise buildings often have multiple households on each floor, and the presence of a fire hazard further obstructs access, preventing people from effectively reaching the escape device. This application addresses this issue by:
[0056] When a fire occurs in a high-rise building and escape is necessary, the displacement traction structure 130 is activated. The displacement traction structure 130 drives the height traction structure 150 and the escape cage 300 to make lateral adjustments through the guide column 110 and guide sleeve 120, so as to accurately adjust the height traction structure 150 and the escape cage 300 above the escape point. Then, the height traction structure 150 is activated to lower the escape cage 300 to the escape point. This improves mobility and allows for all-round coverage of the building, so as to facilitate subsequent precise rescue.
[0057] In this embodiment of the utility model, such as Figure 2 and Figure 3 As shown: The displacement traction structure 130 includes:
[0058] The take-up drum 1303 is mounted on the high-traction structure 150;
[0059] A take-up reel 1302 is attached to one end of the take-up drum 1303;
[0060] The take-up reel 2 1305 is attached to the other end of the take-up reel 1303.

[0071] Furthermore, such as Figure 6 As shown: The material of the upright plate 330 is heat-insulating and flame-retardant material.
[0072] It should be added that: heat-insulating and flame-retardant materials are a type of material that combines the functions of heat insulation (reducing heat transfer) and flame retardancy (inhibiting or delaying combustion);
[0073] Common heat-insulating and flame-retardant materials include inorganic materials, organic-inorganic composite materials, and metal-based materials. Inorganic materials include rock wool, glass wool, ceramic fibers, and aerogel. Aerogel has a nanoporous structure and an ultra-low thermal conductivity (0.015-0.025 W / m·K), and is both lightweight and flame-retardant, making it suitable for heat insulation in high-end equipment or batteries. Organic-inorganic composite materials include intumescent fire-retardant coatings and flame-retardant polymer composite materials. Metal-based materials include metal foil composite materials and metal-ceramic coatings.

[0077] Multiple air outlets 3303 are provided on the upright plate 330 outside the air guide channel 3302. The multiple air outlets 3303 are distributed at equal intervals along the main body of the upright plate 330. The air outlets 3303 are connected to the air guide channel 3302. All the multiple air outlets 3303 face the outside of the escape cage 310.
[0078] It should be noted that the exhaust fan 230 and its power supply wiring method are existing technologies. Their detailed structure can be found in existing literature and journals, and they can also be purchased directly on the market, or components can be purchased on the market to assemble them, etc. They are not what this invention is meant to protect, and will not be described in detail here, nor are they shown in the accompanying drawings.
[0079] In this embodiment of the invention, when a fire occurs in a high-rise building and escape is required, the exhaust fan 230 is activated to ventilate the interior of the air guide channels 3302 in the multiple vertical panels 330, thereby creating a stable external exhaust flow inside the air guide channels 3302.
