Description

Technical Field

[0001] This invention relates to a fire rescue method, particularly a fire rescue method for high-rise buildings and a device for delivering a rescue capsule to implement the method. Background Technology

[0002] Currently, the main technical solutions for rescuing people trapped in balconies, windows, and other similar locations during high-rise building fires are as follows:

[0003] 1. Drone delivery of rescue supplies: In existing technologies, drones are used to carry supply packages and deliver rescue supplies (such as breathing masks, fire blankets, water, etc.) to trapped personnel from top to bottom via ropes or free fall. This method can usually only deliver small and scattered rescue items and cannot provide trapped personnel with a closed and safe survival space.

[0004] 2. Aerial fire trucks and aerial platforms: Large ground equipment such as aerial fire trucks and ladder trucks are used to lift the working bucket to the location of the trapped people through the telescopic boom for rescue. This solution is limited by the building height (usually not exceeding 100 meters), site environment (such as narrow roads and green belts obstructing the way), and deployment time, and has poor applicability in super high-rise buildings or complex terrain.

[0005] 3. Drone-mounted fire extinguishing bombs / fire extinguishing agents: Some technical solutions utilize drones to carry fire extinguishing bombs or spray fire extinguishing agents to suppress the fire source. The core objective is to extinguish the fire, rather than to provide long-term isolation, protection, and life support for trapped personnel.

[0006] 4. Fixed refuge rooms: Some high-rise buildings are designed with fire refuge rooms, but their locations are fixed, and trapped people need to move to them on their own. When the fire spreads rapidly, the movement path may be blocked.

[0007] None of the aforementioned existing technical solutions involve an integrated rescue device that can be precisely delivered via an aerial platform, deployed in narrow spaces such as balconies / windows, and form a closed fireproof and heat-insulating environment; and that provides oxygen and emergency supplies. Summary of the Invention

[0008] In view of the shortcomings of the prior art, the purpose of this invention is to provide a high-rise building fire rescue method and a rescue capsule delivery device. The high-rise building fire rescue method is reasonably designed and is conducive to providing trapped personnel with a physical barrier against flames and high temperatures, and providing ample time for rescue.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] The present invention relates to a high-rise building fire rescue method, characterized in that: a protective cabin compressed in a delivery tube is transported by a drone to the balcony or window of the high-rise building on fire. After the delivery tube pushes the protective cabin into the balcony or window (i.e., indoors), the compressed protective cabin unfolds after being freed from the delivery tube. The affected people enter the unfolded protective cabin, which has fireproof function, to avoid the fire.

[0011] Preferably, the aforementioned protective chamber includes a compressible elastic frame and a heat-insulating and fireproof cloth covering the elastic frame.

[0012] Preferably, the above-mentioned elastic frame is formed by multiple arched spring rods evenly distributed along the circumference, the arched spring rods intersecting and fixing each other at the upper end of the arch, and each spring rod is connected and fixed to the heat-insulating and fireproof cloth.

[0013] Preferably, the aforementioned protective cabin is also equipped with a rescue supplies storage bin, which contains oxygen cylinders, oxygen masks, and emergency lights.

[0014] Preferably, after delivery, the trapped personnel take and wear the oxygen mask delivered by the drone, or the internal lighting of the protective cabin automatically turns on, and the trapped personnel enter the cabin to wear the oxygen mask.

[0015] The present invention provides a life-delivery capsule device for implementing any of the above methods, characterized in that it includes a delivery tube, a delivery tube position adjustment mechanism, and a drone. The delivery tube is mounted on the delivery tube position adjustment mechanism to adjust the pitch angle, forward and backward angle, and left and right angle of the delivery tube. The delivery tube position adjustment mechanism is detachably connected to the lower part of the drone.

[0016] Preferably, the aforementioned delivery tube position adjustment mechanism includes a fixed base that can be detachably connected to the UAV and a pitch adjustment mechanism, a front-to-back adjustment mechanism, and a left-to-right adjustment mechanism connected to the fixed base.

[0017] Preferably, the pitch adjustment mechanism includes a first driving member fixedly mounted on a fixed base. The output end of the first driving member is connected to a worm gear. A worm wheel, meshing with the worm gear, is rotatably connected to the fixed base. The worm wheel is fixedly connected to the first end of a first swing arm, and the second end of the first swing arm is fixedly connected to a first driving member mounting platform. When the first driving member is working, it drives the worm gear and worm wheel to rotate, thereby causing the first swing arm and the first driving member mounting platform to swing in the pitch direction. The front-to-back adjustment mechanism includes two sets of second driving members fixedly mounted on the front and rear of the first driving member mounting platform. The output ends of the two sets of second driving members are respectively connected to second driving member swing rods. The free ends of the two sets of second driving member swing rods are respectively connected to the front and rear of the second driving member mounting platform. The first driving member mounting platform and the second driving member mounting platform are connected to each other. A main fixed shaft is installed between the platforms. The first end of the main fixed shaft is fixedly connected to the first drive component mounting platform, and the middle part of the main fixed shaft is rotatably connected to the second drive component mounting platform. When a set of second drive components is working, it drives a second drive component swing rod to swing the second drive component mounting platform around the main fixed shaft to the front or back. The second end of the main fixed shaft is connected to a universal joint fixed shaft through a universal joint. The universal joint fixed shaft is fixed on the delivery pipe fixing frame. Four sets of third drive components and third drive component swing rods are installed on the second drive component mounting platform. The free ends of the four sets of third drive component swing rods are respectively connected to the four corners of the delivery pipe fixing frame. When the third drive components are working, they drive the third drive component swing rods, the delivery pipe fixing frame, and the delivery pipe to swing in the pitch direction and the left and right direction.

[0018] Preferably, the rear of the delivery tube is equipped with a push rod capable of pushing out the compressed protective chamber in the delivery tube, the push rod being driven by a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0019] Preferably, both the second and third driving component swing rods include a swing arm, a connecting rod, and a pin. The inner end of the swing arm is directly connected to the output end of the driving component. The free end of the swing arm is hinged to the first end of the connecting rod, and the second end of the connecting rod is hinged to the outer end of the pin. The inner end of the pin is fixedly connected to the second driving component mounting platform or the delivery pipe fixing frame.

[0020] This application has the following technical advantages compared to the prior art:

[0021] 1. Extreme rescue timeliness and rapid response capability: This application relies on an aerial mobile drone platform. From takeoff from the ground, flying to the target floor, hovering and aiming, to completing the delivery and deployment of the protective cabin, the entire process can be completed in a short time. From the time the drone arrives at the fire scene to the protective cabin being pushed out and fully deployed, it takes about 11-15 seconds. Compared with the lifting time of several minutes to more than ten minutes after the aerial ladder truck arrives at the scene, this application achieves a near-zero-delay rescue of "delivery upon arrival and deployment upon delivery", winning precious survival time for trapped personnel.

[0022] 2. This innovative approach provides a closed, safe space. It fundamentally changes the traditional "supply delivery" rescue model, upgrading it to a "safe space delivery" model. This creates a complete, physically isolated fireproof and heat-insulated cabin for trapped personnel, separating them from the fire environment and significantly increasing their survival probability. This is achieved through the overall architecture of a remotely deployable, automatically deployable fireproof rescue cabin system.

[0023] 3. Ease of operation and reliability: The rescue process requires almost no operation from the trapped personnel. They only need to enter the deployed protective cabin. Furthermore, the deployment of the protective cabin adopts a purely mechanical energy storage and release method, which does not rely on electricity.

[0024] 4. Achieving high-precision non-contact delivery in narrow spaces at high altitudes: This application breaks through the height and site limitations of ground equipment and achieves for the first time high-precision delivery to typical trapped locations such as balconies and windows of high-rise buildings.

[0025] 5. Complete life support and humanized design: The protective cabin of this application integrates four major functions: oxygen supply, lighting, water supply, and fire prevention.

[0026] 6. Economy and sustainability: This application adopts a design that separates the "reusable delivery platform (delivery pipe and delivery pipe position adjustment mechanism, etc.)" from the "disposable protective cabin". This design not only ensures the high utilization rate of the core delivery equipment, but also makes the material cost of a single rescue controllable through modular design, which is conducive to large-scale equipment deployment.

[0127] To make the above features and advantages of the present invention more obvious and understandable, specific embodiments are hereinafter given and described in detail in conjunction with the accompanying drawings. However, the present invention is not limited thereto.

[0128] The high-rise building fire rescue method of the present invention transports the protection cabin A1 compressed in the delivery pipe 1 to the balcony of the high-rise building on fire by an unmanned aerial vehicle. After the delivery pipe 1 pushes the protection cabin A1 to fall to the balcony, the compressed protection cabin expands after breaking free from the restraint of the delivery pipe, and the affected people enter the expanded protection cabin with fire prevention function to avoid the fire.

[0129] Specifically, the protection cabin A1 includes an elastic framework that can be compressed and a heat-insulating and fire-proof cloth 32 covering the elastic framework. The elastic framework is formed by a plurality of arched spring rods 28 evenly distributed along the circumference. The arched spring rods are fixedly crossed with each other at the upper end of the arch, and each spring rod 28 is fixedly connected to the heat-insulating and fire-proof cloth 32.

[0130] The above protection cabin A1 is a disposable item. In the unexpanded state, the protection cabin is cylindrical (with a diameter of 30 - 60 cm and a length of 1.5 - 2 m), folded and accommodated in the delivery pipe. The spring rods 28 are made of high-elastic spring steel sheets or spring steel bars. These spring rods 28 are arranged in a "rice" shape in the top view of the elastic framework. When in the delivery pipe, the tube wall constraint makes the elastic framework and spring rods in an energy storage state; after being pushed out of the delivery pipe nozzle, the constraint is instantly released, and the spring rods elastically reset, driving the elastic framework and the heat-insulating and fire-proof cloth to complete the expansion within 1 - 5 seconds, forming a closed cylindrical or hemispherical space with a diameter ≥ 1 - 2 m and a height ≥ 1.5 - 2 m; through comparative tests, the protection cabin of the present invention only takes 1 - 5 seconds from being pushed out to being fully expanded, while the existing inflatable protection cabins usually take more than 10 seconds, and the protection cabin of the present invention is purely mechanically expanded without relying on external power or gas source, with higher reliability.

[0131] One embodiment of the spring rod can adopt a 65Mn spring steel rod with a diameter of 6 - 10 mm. After heat treatment, the yield strength is ≥ 520 MPa. A plurality of arched spring rods are evenly distributed, and after expansion, they can support a hemispherical fire-proof cabin with a diameter of 2 m and a height of 1.8 m.

[0132] The heat-insulating and fire-proof cloth can be ceramic fiber cloth, high-silica cloth, carbon fiber cloth, etc.; or it can also adopt a multi-layer composite material. The outer layer is a polycrystalline mullite fiber blanket, and the inner layer is a high flame-retardant cloth of the same grade as the fire-fighter's fire-fighting protective clothing. The two are compounded, which can effectively resist the direct impact of the flame and isolate heat conduction.

[0133] The protective cabin A1 is also equipped with a rescue supplies storage bin 29, which can hold bottled drinking water, oxygen cylinders, oxygen masks and emergency lights. These bottled drinking water, oxygen cylinders, oxygen masks and emergency lights can be commercially available components, which will not be described in detail here.

[0134] This application features a highly streamlined workflow, enabling a rapid response mode of "deployment upon arrival and deployment upon deployment." The entire process requires no ground preparation, is not limited by location, and greatly reduces the time window for rescue operations. The specific work steps are as follows:

[0135] The first step, mounting and takeoff: Ground personnel load the folded fireproof protective cabin into the delivery tube, and the industrial drone carrying the device flies to the fire scene of the high-rise building and hovers outside the balcony or window where the trapped people are located.

[0136] The second step is aiming and alignment: The ground pilot controls the delivery tube position adjustment mechanism through the remote control system to precisely adjust the attitude of the delivery tube. Using the laser infrared composite aiming module, the pilot waits for the controller to determine that the ranging data is stable before outputting an "aiming lock" signal to confirm the optimal docking attitude and distance between the delivery tube opening and the target window.

[0137] The third step is delivery and deployment: After confirming alignment and receiving the "aiming lock" signal, the pilot issues a delivery command, the push stick is activated, and the folded protective cabin is smoothly pushed away from the delivery tube opening. As soon as the protective cabin leaves the delivery tube, the internal spring rod immediately loses its restraint and instantly elastically resets, driving the cabin to unfold into a closed fireproof space, covering the balcony or window area.

[0138] The fourth step is rescue and shelter: After the protective cabin is deployed, the emergency lights will turn on. The trapped personnel will enter the cabin and put on oxygen masks, or the trapped personnel will take and put on oxygen masks delivered by drones after being dropped.

[0139] Step 5, Life Support: After the protective cabin is deployed, the heat-insulating and fireproof cloth provides protection against flames and heat radiation, while bottled drinking water and emergency lights create valuable conditions for trapped personnel to wait for rescue.

[0140] To implement the aforementioned high-rise building fire rescue method, the delivery pipe 1 is installed on the delivery pipe position adjustment mechanism A2 to adjust the pitch angle, forward / backward angle, and left / right angle of the delivery pipe 1. The delivery pipe position adjustment mechanism A2 is detachably connected to the lower part of the drone (drone not shown in the figure). The pitch angle is... Figure 2 The rotation around the Z-axis, the front and back angles are... Figure 2 The rotation around the X-axis, the left and right angles are... Figure 2 Rotation around the Y-axis.

[0141] The specific delivery tube position adjustment mechanism A2 includes a fixed base A3 that can be detachably connected to the UAV, and a pitch adjustment mechanism A4, a forward and backward adjustment mechanism A5, and a left and right adjustment mechanism A6 connected to the fixed base A3.

[0142] The pitch adjustment mechanism A4 includes a first drive component 73 fixedly mounted on a fixed base A3. The output end of the first drive component is connected to a worm gear 67. A worm wheel A7, which meshes with the worm gear, is rotatably connected to the fixed base. The worm wheel A7 is fixedly connected to the first end of a first swing arm A8, and the second end of the first swing arm is fixedly connected to a first drive component mounting platform A9. When the first drive component is working, it drives the worm gear and worm wheel to rotate, causing the first swing arm and the first drive component mounting platform to swing around the axis of the worm wheel A7 in the pitch direction (i.e., around the axis of the worm wheel A7). Figure 2 The Z-axis of the delivery tube 1 can be adjusted up and down within the range of 0 to 45 degrees through the first driving component (usually adjusted to about 45 degrees during delivery). The self-locking characteristic of the worm gear ensures that the angle remains stable at the moment of delivery, preventing deviation caused by external impact.

[0143] The front and rear adjustment mechanism A5 includes two sets of second drive components 37 fixedly installed on the front and rear of the first drive component mounting platform A9 (the front and rear parts here are also known as the first drive component mounting platform A9). Figure 2 (The two sets of second drive components are located at the front and rear positions along the Z-axis). The output ends of the two sets of second drive components are respectively connected to the second drive component swing rods 36. The free ends of the two sets of second drive component swing rods are respectively connected to the front and rear parts of the second drive component mounting platform A10 (the front and rear parts here are also known as the front and rear parts). Figure 2 (The front and rear positions along the Z-axis), a main fixed shaft 49 is installed between the first drive component mounting platform and the second drive component mounting platform (the axis of the main fixed shaft 49 is along the Z-axis). Figure 2 (X-axis direction setting), the first end of the main fixed shaft is fixedly connected to the first drive component mounting platform A9, and the middle part of the main fixed shaft is rotatably connected to the second drive component mounting platform A10. When a set of second drive components is working, it drives a second drive component swing rod to move, causing the second drive component mounting platform to swing forward or backward around the main fixed shaft, that is, around the main fixed shaft. Figure 2 The X-axis direction is rotated towards the Z-axis direction (forward and backward). This forward and backward rotation adjustment is to overcome the wobbling of the drone under wind conditions, and to adjust the balance attitude of the delivery tube. Figure 2 As shown, if the second drive unit located on the front side drives the swing arm of the second drive unit located on the front side to move (the swing arm of the second drive unit located on the rear side does not move relative to it), then the second drive unit mounting platform and the delivery pipe swing forward around the main fixed axis, and vice versa.

[0144] The second end of the main fixed shaft 49 is connected to the universal joint fixed shaft 43 via a universal joint 44. The universal joint fixed shaft is fixed on the delivery pipe fixing frame 33 (specifically, on the upper and lower symmetrical plates 34 of the delivery pipe fixing frame). Four sets of third drive components 42 and third drive component swing rods 41 are mounted on the second drive component mounting platform. The free ends of the four sets of third drive component swing rods are respectively connected to the four corners of the delivery pipe fixing frame 33. When the third drive component is working, it drives the third drive component swing rods, the delivery pipe fixing frame, and the delivery pipe to swing in the pitch direction and left and right directions. The pitch direction here is... Figure 2 The rotation around the Z-axis (the pitch adjustment here is to overcome the yaw caused by wind on the UAV, and to adjust the balance of the delivery tube; this pitch angle is 1-15 degrees, which is different from the function and adjustment degree of the first drive component mentioned above), the left and right directions here are... Figure 2 Rotate around the Y-axis (the left and right sway adjustment here is also to overcome the swaying of the drone when it is blown by the wind, so as to adjust the balance attitude of the delivery tube).

[0145] like Figure 2 As shown, if the two sets of third drive components on the front side drive the swing rod of the third drive component on the front side to move (the third drive component and the swing rod of the third drive component on the rear side do not move relative to each other), then the delivery tube fixing frame and the delivery tube will swing to the left around the Y-axis, and vice versa.

[0146] like Figure 2 As shown, if the two sets of third drive components on the upper side drive the swing rod of the third drive component on the upper side to move (the third drive component and the swing rod of the third drive component on the lower side do not move relative to each other), then the delivery tube fixing frame and the delivery tube will swing upward around the Z-axis (i.e., tilt upward), and vice versa (i.e., tilt downward).

[0147] The first drive unit, the second drive unit, and the third drive unit can each be independently selected as a servo motor, an electric actuator, or a hydraulic motor.

[0148] The rear of the delivery tube is equipped with a push rod 8 that can push out the compressed protective chamber in the delivery tube. The push rod is driven by a hydraulic cylinder 12, a pneumatic cylinder, or an electric cylinder.

[0149] Additionally, a laser-infrared composite aiming module, including a laser rangefinder and an infrared spot emitter, can be installed at the front end of the delivery tube. The ground pilot can simultaneously observe the infrared spot projected onto the target and the aiming ring linked to the ranging data through the FPV screen. The delivery device (including the delivery tube and the delivery tube position adjustment mechanism, etc.) has a built-in controller. The controller continuously receives laser ranging data. When the ranging value fluctuates less than a preset threshold (e.g., ±5cm) and continues for more than a preset time (e.g., 2 seconds), the controller automatically sends an "aiming lock" signal to the ground station (ground pilot end) and allows push command execution. This judgment logic effectively avoids misjudgment caused by platform hovering and drifting.

[0150] This application has the following technical advantages compared to the prior art:

[0151] 1. Extreme rescue timeliness and rapid response capability: This application relies on an aerial mobile drone platform. From takeoff from the ground, flying to the target floor, hovering and aiming, to completing the delivery and deployment of the protective cabin, the entire process can be completed in a short time. From the time the drone arrives at the fire scene to the protective cabin being pushed out and fully deployed, it takes about 11-15 seconds. Compared with the lifting time of several minutes to more than ten minutes after the aerial ladder truck arrives at the scene, this application achieves a near-zero-delay rescue of "delivery upon arrival and deployment upon delivery", winning precious survival time for trapped personnel.

[0152] 2. This innovative approach provides a closed, safe space. It fundamentally changes the traditional "supply delivery" rescue model, upgrading it to a "safe space delivery" model. This creates a complete, physically isolated fireproof and heat-insulated cabin for trapped personnel, separating them from the fire environment and significantly increasing their survival probability. This is achieved through the overall architecture of a remotely deployable, automatically deployable fireproof rescue cabin system.

[0153] 3. Ease of operation and reliability: The rescue process requires almost no operation from the trapped personnel. They only need to enter the deployed protective cabin. Furthermore, the deployment of the protective cabin adopts a purely mechanical energy storage and release method, which does not rely on electricity.

[0154] 4. Achieving high-precision non-contact delivery in narrow spaces at high altitudes: This application breaks through the height and site limitations of ground equipment and achieves for the first time high-precision delivery to typical trapped locations such as balconies and windows of high-rise buildings.

[0155] 5. Complete life support and humanized design: The protective cabin of this application integrates four major functions: oxygen supply, lighting, water supply, and fire prevention.

[0156] 6. Economy and sustainability: This application adopts a design that separates the "reusable delivery platform (delivery pipe and delivery pipe position adjustment mechanism, etc.)" from the "disposable protective cabin". This design not only ensures the high utilization rate of the core delivery equipment, but also makes the material cost of a single rescue controllable through modular design, which is conducive to large-scale equipment deployment.
