Description

Technical Field

[0001] This invention relates to the field of fire protection equipment technology for high-rise buildings, and more specifically to a fire protection device and method for high-rise buildings. Background Technology

[0002] Fighting fires in high-rise buildings has always been a global technical challenge in the fire protection field. As urban buildings continue to rise higher, fires in high-rise buildings often spread rapidly and are extremely difficult to extinguish, easily causing serious casualties and property damage.

[0003] Currently, fire prevention and fighting in high-rise buildings mainly rely on the following methods, but all of them have significant limitations:

[0004] First, the effectiveness of fixed fire protection facilities installed inside buildings, such as fire hydrant systems and automatic sprinkler systems, depends on the integrity of the building's interior and the continuous pressure of the water supply system. In the event of a fire causing a power outage, pipe damage, or insufficient water supply, such systems may completely fail and cannot perform their intended function.

[0005] Secondly, the rescue model relying on ground fire trucks has inherent flaws. Even with ladder trucks or high-pressure water cannons, their operating height is usually limited, often rendering them ineffective against fires in the middle and upper parts of high-rise buildings over 100 meters tall. Furthermore, the purchase and maintenance costs of specialized fire trucks are extremely high, and due to limitations imposed by urban traffic conditions and on-site operating space, the time required to reach the fire scene and commence effective operations is long, easily leading to missed opportunities for optimal firefighting.

[0006] In recent years, with the development of drone technology, attempts and concepts have emerged to utilize drones for firefighting operations. However, existing demonstration solutions are mostly limited to drones directly carrying small fire extinguishing agent canisters or short water hoses for spraying. Due to the strict limitations of drones' own payload and endurance, the amount of fire extinguishing medium they can carry is extremely limited, and the spray flow rate and duration are far from sufficient to meet the large-scale, high-intensity combustion requirements of real high-rise building fires, resulting in serious lack of practicality. Summary of the Invention

[0007] (a) Technical problems to be solved

[0008] To address the aforementioned problems, this invention provides a high-rise building fire-fighting device and method. By combining a fire-fighting drone, a transferable hose system, and a rooftop mobile fire-fighting platform, a highly efficient and collaborative external fire-fighting system for high-rise buildings is constructed. The core of this solution lies in: utilizing a mobile platform for rapid positioning; reliably supporting and deploying long-distance hoses with internal wiring via a drive device and conveyor chain; and using a drone to carry nozzles at the hose's end for precise and mobile fire suppression, while a winch and wire rope provide auxiliary suspension. This integrated solution achieves rapid response, continuous high-flow water supply, ultra-high-altitude operational coverage, and three-dimensional flexible positioning of the fire-fighting nozzles, effectively overcoming key bottlenecks in existing high-rise building fire-fighting technologies such as slow response, insufficient water pressure and flow, limited drone payload, and easily damaged hoses.

[0009] (II) Technical Solution

[0010] To address the aforementioned technical problems, embodiments of the present invention provide a high-rise building fire protection device and method.

[0011] According to a first aspect of the present invention, a high-rise fire-fighting device is provided, comprising: a mobile fire-fighting platform disposed on the top of a high-rise building; a conveyor hose including a conveyor chain and a hose mounted on the conveyor chain, the front end of the hose being connected to a hose connector, and the end of the hose being provided with a hose nozzle, the hose nozzle being provided with a latch for locking with a drone and a charging connector; a drone configured to engage and lock with the latch on the hose nozzle and obtain power through the charging connector; wherein, the mobile fire-fighting platform is provided with a drive device, the drive device being provided with a drive gear, the drive gear engaging with the conveyor chain for transmission; the mobile fire-fighting platform is also provided with a telescopic boom device, the telescopic boom device including a telescopic arm and a winch, the end of the telescopic arm being provided with a guide gear and a hook, the winch being connected to the hook via a wire rope; a lifting ring is connected to the end of the conveyor chain, and the free end of the wire rope is connected to the lifting ring.

[0012] In some exemplary embodiments, the conveyor chain includes chain links that are hinged in sequence, each chain link including a right side plate and a left side plate disposed opposite to each other; the upper part of the right side plate is provided with a right clamping plate, the upper part of the left side plate is provided with a left clamping plate, and a chain gap for clamping water hose is formed between the right clamping plate and the left clamping plate.

[0013] In some exemplary embodiments, the right clamp has multiple right clamp holes, and the left clamp has multiple left clamp holes, with the right clamp holes and left clamp holes aligned one by one; the bottom of the water hose forms a water hose folded portion, which is inserted into the chain gap and fixed by a connector passing through the right clamp hole and the left clamp hole.

[0014] In some exemplary embodiments, the mobile fire-fighting platform also includes a platform plate, with a moving device located below the platform plate. The moving device cooperates with a track laid on the roof to allow the mobile fire-fighting platform to move along the track.

[0015] In some exemplary embodiments, the platform plate is provided with two guide slots, one of which is located near the drive unit and the other is located at the end of the telescopic arm; the guide slots are provided with chain grooves for the conveyor chain to pass through.

[0016] In some exemplary embodiments, a first blocking ring and a second blocking ring are respectively fitted at the beginning and end of the conveyor chain, and the first blocking ring and the second blocking ring are fitted outside the water hose; a detachable third blocking ring is provided on the guide groove, and the water hose passes through the third blocking ring; the inner diameter of the third blocking ring is smaller than the outer diameter of the first blocking ring and the second blocking ring.

[0017] In some exemplary embodiments, an electric wire is embedded in the hose, one end of which is electrically connected to a charging connector on the hose nozzle, and the other end is connected to an external power source via the hose connector.

[0018] In some exemplary embodiments, the mobile fire-fighting platform is also equipped with a nozzle base for supporting water hose nozzles that are not connected to the drone.

[0019] In some exemplary embodiments, the hose connector is connected to a water tank located on the roof.

[0020] According to a second aspect of the present invention, a method for high-rise fire fighting is provided, employing the aforementioned high-rise fire fighting device, comprising the following steps: a remotely controlled drone flies to the rooftop and docks with a water hose nozzle placed on a nozzle base, locking the drone's locking mechanism and latch, and connecting the drone's power interface to the charging connector; the drone takes off carrying the water hose nozzle and hovers outside the building; the drive device is activated, causing the drive gear to rotate, driving the conveyor chain and water hose to be conveyed outward; simultaneously, the telescopic arm is controlled to extend outward, and the winch is controlled to release the wire rope; the water hose and conveyor chain descend under the guidance of gravity and the suspension of the wire rope, and the drone descends synchronously until the water hose nozzle reaches the target floor height; the mobile fire platform is controlled to move along the track, so that the hovering drone is aligned with the fire point; the water source of the rooftop water tank is connected through the water hose connector, and the remotely controlled drone operates the water hose nozzle to spray water for fire extinguishing; wherein, during the fire extinguishing process, the spray direction is adjusted by the remotely controlled drone, and / or the drive device and winch are controlled to move synchronously to raise or lower the height of the water hose nozzle.

[0021] (III) Beneficial Effects

[0022] As can be seen from the above technical solutions, the high-rise building fire protection device and method provided by the embodiments of the present invention have at least the following beneficial effects:

[0023] (1) Rapid response and high fire-fighting mobility: Fire-fighting drones are usually centrally deployed in fire brigades. When a fire occurs, they can quickly fly to the roof of the building and quickly connect with the pre-positioned mobile fire-fighting platform and water delivery gun, saving the time of long-distance dispatch and deployment of large fire trucks. The drones equipped with nozzles can flexibly fly to the windows of any floor, realizing the efficient and accurate delivery of fire extinguishing agents.

[0024] (2) Solved the water supply problem for super high-rise buildings: By fixing the water hose (with built-in wires) to the conveyor chain and coordinating its opening and closing with the drive device on the roof and the winch, the huge weight of the water hose and the water flow within it is mainly borne by the mechanical structure (chain and wire rope), rather than by the water hose itself or its joints. This fundamentally avoids the risk of ordinary water hoses collapsing, breaking, or joints falling off due to excessive hydrostatic pressure, making it possible to stably deliver large volumes of extinguishing agent to fire points hundreds of meters high.

[0025] (3) The system has high reliability and good fault tolerance: the conveyor chain wraps around and protects the water hose. Even if the water hose is partially damaged due to long-term exposure or accidental impact, the damaged area is not easy to tear and expand under pressure, which significantly improves the reliability of the fire extinguishing operation. At the same time, the use of limiting mechanisms such as blocking rings can effectively prevent the conveyor chain from coming off the drive system, ensuring operational safety.

[0026] (4) Ensures the continuous operation capability of the drone: The built-in wires of the water hose can provide power to the drone in real time during the fire extinguishing process, which breaks through the limitation of the short battery life of the drone and enables it to carry out long-term, uninterrupted fire extinguishing operations to cope with large-scale fires.

[0027] (5) Flexible deployment and strong scalability: Multiple mobile fire-fighting platforms can be arranged along the surrounding tracks on the rooftop to achieve fire-fighting coverage without blind spots. In the event of a fire, multiple drones and multiple platforms can be dispatched to work together to extinguish the fire from different directions simultaneously, greatly improving fire-fighting efficiency. This device can also be used for automated cleaning of high-rise building facades and other operations to improve equipment utilization. Attached Figure Description

[0079] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0080] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The terms “comprising,” “including,” etc., as used herein indicate the presence of features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0081] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way.

[0082] Figure 1 The schematic diagram illustrates the structure of a high-rise fire protection device according to an embodiment of the present invention.

[0083] like Figure 1 As shown, the high-rise fire-fighting device according to an embodiment of the present invention includes: a mobile fire-fighting platform 701, installed on the top of the high-rise building; a conveyor water gun, including a conveyor chain 201 and a water hose 301 mounted on the conveyor chain 201, the front end of the water hose 301 being connected to a water hose connector 501, and the end being equipped with a water hose nozzle 401, the water hose nozzle 401 being provided with a latch 4011 for locking with a drone and a charging connector 4012; a drone, configured to dock and lock with the latch 4011 on the water hose nozzle 401, and to obtain power through the charging connector 4012; wherein, the mobile fire-fighting platform 701 is provided with a drive device 7013, the drive device 7013 being provided with a drive gear 70131, the drive gear 70131 being engaged with the conveyor chain 201 for transmission. The mobile fire-fighting platform 701 is also equipped with a telescopic boom device 7014, which includes a telescopic boom 70141 and a winch 70143. The end of the telescopic boom 70141 is equipped with a guide gear 70142 and a hook 70144. The winch 70143 is connected to the hook 70144 via a wire rope 701431. The end of the transmission chain 201 is connected to a lifting ring 20151, and the free end of the wire rope 701431 is connected to the lifting ring 20151.

[0084] The high-rise fire-fighting device provided in the embodiments of the present invention has the core principle of constructing an "airborne mobile water supply terminal", which achieves efficient fire extinguishing outside the high-rise building through the coordinated operation of drones, water hoses 301, mechanical conveying systems and rooftop platforms. Specifically, during system operation: Normally, the hose nozzle 401 is placed on the nozzle base 7016 of the rooftop mobile fire-fighting platform 701. In the event of a fire, the fire-fighting drone quickly flies to the rooftop, docks with the nozzle, locks onto it, and connects its built-in power supply. Subsequently, the drone carries the nozzle outside the building, and the rooftop drive unit 7013 is activated. Through the engagement of the drive gear 70131 and the transmission chain 201, the transmission chain 201, which holds the hose 301, is extended outwards. Simultaneously, the telescopic boom extends outwards, and the winch 70143 releases the wire rope 701431 to suspend the chain and the end of the hose 301. Under the combined action of the hose 301's own weight, chain drive, and wire rope 701431's traction, the hose 301 descends smoothly, and the drone lands simultaneously at the target floor height. The mobile platform can move horizontally along the rooftop track 1001, allowing the drone to precisely target the fire. Finally, once the water supply is connected, the drone can perform high-flow, continuous, and precise water spraying for fire extinguishing. If height adjustment is required, the drive unit 7013 and the winch 70143 can be reversed synchronously to quickly recover the water hose 301 and the nozzle.

[0085] Corresponding to the above working principle, this device brings several significant benefits: First, the system has a fast response and high mobility, allowing drones to quickly arrive and deploy, overcoming the limitations of slow dispatch and difficult access to high altitudes faced by large fire trucks. Second, it innovatively solves the problem of water supply in ultra-high-rise buildings. By fixing the hose 301 to the conveyor chain 201 and using steel wire rope 701431 for auxiliary load-bearing, the hose 301 is not subjected to longitudinal tension, avoiding deformation and breakage caused by excessive hydrostatic pressure, and achieving stable delivery of large-flow extinguishing agent to altitudes of hundreds of meters. Third, the system has high reliability and good fault tolerance. The chain protects the hose 301, preventing further damage even if it is partially broken, and the design of the blocking rings prevents chain slippage. Fourth, it ensures the continuous operation capability of drones, achieving continuous power supply through the internal cable of the hose 301, breaking through the battery life bottleneck. Fifth, it has good scalability and multi-functionality. Multiple platforms can be deployed on the rooftop to achieve all-round coverage and coordinated fire fighting. The system can also be used for high-rise cleaning and other operations, improving equipment utilization.

[0086] Figure 2 A schematic diagram of the structure of a conveyor chain 201 according to an embodiment of the present invention is shown. Figure 3 This schematic diagram illustrates the structure of the right side plate 2011 of the conveyor chain 201 according to an embodiment of the present invention; Figure 4 The schematic diagram shows the structure of the left side plate 2012 of the conveyor chain 201 according to an embodiment of the present invention.

[0087] like Figures 2-4 As shown, the conveyor chain 201 according to an embodiment of the present invention includes chain links hinged sequentially. Each chain link includes a right side plate 2011 and a left side plate 2012 disposed opposite to each other. A right clamping plate 20111 is provided on the upper part of the right side plate 2011, and a left clamping plate 20121 is provided on the upper part of the left side plate 2012. A chain slot 2013 for securing the water hose 301 is formed between the right clamping plate 20111 and the left clamping plate 20121. The right clamping plate 20111 has a plurality of right clamping plate holes 201111, and the left clamping plate 20121 has a plurality of left clamping plate holes 201211, with the right clamping plate holes 201111 and the left clamping plate holes 201211 aligned one-to-one. Compared with a conventional chain 101 (see...), this chain... Figure 5 According to an embodiment of the present invention, the conveyor chain 201 is designed with perforated right clamps 20111 and left clamps 20121 on each link, forming a chain gap 2013 between them. This allows the folded portion of the hose 301 to be embedded within the gap and secured using connectors passing through the aligned clamp holes, thus structurally integrating the flexible hose 301 with the rigid chain. This design transforms the hose 301 from a traditional independent pressure-bearing pipeline into a "composite conveyor unit" supported and pulled by the chain. Its direct benefits are that the hose 301 itself no longer primarily bears longitudinal tension and hydrostatic pressure; these loads are effectively transferred and distributed to the robust chain mechanism. This not only completely avoids the problems of crushing, cracking, and joint detachment that easily occur with ultra-long hoses 301 under heavy loads, but also significantly improves the reliability, stability, and durability of the entire water supply system during operations at heights of hundreds of meters. It is a key structural innovation for achieving continuous high-flow water supply to high-rise buildings.

[0088] Figure 6 A schematic diagram of the structure of the water hose 301 according to an embodiment of the present invention is shown.

[0089] like Figure 6 As shown, according to an embodiment of the present invention, the bottom of the water hose 301 forms a water hose folding portion 3011, which is inserted into the chain slot 2013 and fixed by a connector passing through the right clip hole 201111 and the left clip hole 201211.

[0090] Figure 7 The schematic diagram illustrates the structure of a water hose 301 installed on a conveyor chain 201 according to an embodiment of the present invention.

[0091] like Figure 7As shown, the folded portion 3011 of the hose is inserted into the chain slot 2013 of the conveyor chain 201. A pointed tool is used to penetrate the folded portion 3011 through each left clamp hole 201211 to form a small hole. Stainless steel wire or other similar rivet components are used to fix the folded portion 3011 to the right clamp 20111 and the left clamp 20121, thus completing the installation of the hose 301 on the conveyor chain 201. By pre-fabricating the folded portion at the bottom of the hose 301 and embedding it into the chain slot 2013, and then using connectors to rivet at multiple points through the aligned right clamp holes 201111 and left clamp holes 201211, structural integration and synchronous transmission between the hose 301 and the chain are achieved. This assembly method not only ensures that the hose 301 does not slip or fall off when subjected to water flow pressure and longitudinal load, but also effectively avoids localized damage to the hose 301 caused by stress concentration due to its distributed fixing design. While maintaining the water supply function of the water hose 301, it is endowed with reliable mechanical load-bearing and transmission capabilities, making the water hose 301 a protected functional component in the transmission system, thereby significantly improving the integrity, durability and maintainability of the entire high-altitude water supply system.

[0092] Figure 8 A schematic diagram of the structure of a water delivery gun according to an embodiment of the present invention is shown.

[0093] like Figure 8 As shown, according to Figure 7 The method shown involves mounting the main body of a single water hose 301, exceeding the height of a building, onto a conveyor chain 201. A first blocking ring 2014 is installed on the right side plate 2011 and left side plate 2012 at the beginning of the conveyor chain 201 to enclose the water hose 301. A second blocking ring 2015 is installed on the right side plate 2011 and left side plate 2012 at the end of the conveyor chain 201 to enclose the water hose 301. The second blocking ring 2015 has a hanging ring 20151 at its top. An electric wire 601 is passed through the water hose 301, and its end is connected to a charging connector 4012 on a water hose nozzle 401. The water hose nozzle 401 is then installed at the end of the water hose 301, and a water hose connector 501 is installed at the front end of the water hose 301, thus completing the installation of the water hose nozzle. The water hose nozzle 401 also has two locking buckles 4011 for locking and docking with a drone.

[0094] By structurally fixing the main body of the extra-long water hose 301 to the conveyor chain 201, and setting a first blocking ring 2014 with a limiting function and a second blocking ring 2015 with a lifting ring 20151 at its two ends, and simultaneously embedding wires 601 and integrating nozzles with locking buckles 4011 and charging connectors 4012, a composite high-altitude operation execution terminal integrating water delivery, power supply, transmission, and docking functions is constructed. Through this structural design, the chain bears most of the weight of the water hose 301 and the water flow, the blocking rings effectively prevent the water hose 301 from axially shifting or detaching during transmission, the lifting rings 20151 provide a reliable force connection point for the external hoisting system, the built-in wires 601 enable long-distance continuous energy delivery, and the standardized nozzle locking buckles 4011 ensure quick and secure docking with the UAV. Overall, this water delivery gun achieves synchronous and reliable transmission of force, water flow, and current, and is the core functional module supporting UAVs for long-term, high-flow, high-altitude mobile firefighting.

[0095] Figure 9 A schematic diagram of the structure of a mobile fire-fighting platform 701 according to an embodiment of the present invention is shown.

[0096] like Figure 9 As shown, the mobile fire-fighting platform 701 according to an embodiment of the present invention includes a platform plate 7011, a moving device 7012 is provided below the platform plate 7011, the moving device 7012 cooperates with a track 1001 laid on the roof, so that the mobile fire-fighting platform 701 moves along the track 1001. A driving device 7013 is provided at the rear of one side of the platform plate 7011, a driving gear 70131 is provided on the driving device 7013, a telescopic boom device 7014 is provided at the front of the same side of the driving device 7013, a telescopic arm 70141 is provided on the telescopic boom device 7014, a guide gear 70142 is provided above the end of the telescopic arm 70141, a winch 70143 is provided below the telescopic boom device 7014, a wire rope 701431 is provided on the winch 70143, a hook 70144 is provided below the end of the telescopic arm 70141, and the end of the wire rope 701431 passes through the hook 70144. The platform plate 7011 is provided with two guide grooves 7015, one of which is located near the drive unit 7013, and the other is located at the end of the telescopic arm 70141; the guide grooves 7015 are provided with chain grooves 70151 for the conveyor chain 201 to pass through. The mobile fire-fighting platform 701 is also provided with a nozzle base 7016 for supporting the water hose nozzles 401 that are not connected to the drone.

[0097] The mobile fire-fighting platform 701 according to an embodiment of the present invention constitutes an integrated control and execution hub for a high-rise building fire-fighting system. Its core working principle lies in achieving rapid horizontal positioning via a platform plate 7011 that can move along the track 1001, and integrating a drive device 7013, a telescopic boom device 7014, and a winch 70143 to form coordinated control of the water hose delivery system. The drive gear 70131 engages with the chain to provide transmission and load-bearing capacity; the telescopic boom 70141 extends the working radius; and the guide gear 70142 at its end ensures correct engagement and guidance of the chain in its suspended state. The winch 70143 is connected to the end of the chain via a wire rope 701431 and a hook 70144, providing stable auxiliary suspension and tension control. The two guide grooves 7015 and the chain groove 70151 on the platform further provide precise constraints and support for the chain along the transmission path, while the nozzle base 7016 is used for the safe storage of standby nozzles. The benefits of this integrated design are significant: the platform has flexible horizontal and vertical adjustment capabilities, enabling it to quickly and accurately aim the fire extinguishing terminal at the fire point; its mechanical structure provides a stable and reliable transmission path and multi-point support for the hose 301 and chain, effectively suppressing high-altitude swaying; at the same time, all power and control units are centrally located, facilitating operation and maintenance, and realizing integrated and coordinated control of positioning, transmission, suspension and recovery functions, which is the key foundation for ensuring the efficient and stable operation of the entire system.

[0098] Figure 10 A schematic diagram of the structure of the telescopic arm 70141 according to an embodiment of the present invention is shown.

[0099] like Figure 10 As shown, the guide groove 7015 is installed at the front of the end of the telescopic boom 70141, and the guide groove 7015 is provided with a chain groove 70151, as shown. Figure 8 The conveyor chain 201 on the water gun shown can pass through the chain groove 70151. The chain groove 70151 has detachable third blocking rings 70152 on both sides. Figure 8 The water hose 301 on the water delivery gun shown can pass through the third blocking ring 70152, the inner diameter of which is smaller than the outer diameter of the first blocking ring 2014 and the second blocking ring 2015.

[0100] The structural design of the end guide groove 7015 of the telescopic boom 70141 according to an embodiment of the present invention follows the principle of combining precise guidance and safety limiting: the chain groove 70151 provided inside provides a rigid motion track 1001 for the transmission chain 201 to pass through the telescopic boom 70141, ensuring the stability of the chain engagement and transmission in the suspended state; while the detachable third blocking ring 70152 allows the water hose 301 to pass through its inner hole and forms axial mechanical interference with the larger first and second blocking rings 2015, effectively preventing the water hose 301 fixed on the chain from accidentally slipping off or the chain from detaching from the chain groove 70151 without affecting the flow of the water hose 301. The beneficial effects of this design are: in complex high-altitude operation conditions, it ensures the smoothness and accuracy of the transmission system operation, provides key safety redundancy through a simple mechanical limiting method, and the detachable structure facilitates the installation and maintenance of the equipment.

[0101] Figure 11 The schematic diagram illustrates a structure of a mobile fire-fighting platform 701 and a water delivery gun mounted on the top of a high-rise building 801 according to an embodiment of the present invention.

[0102] like Figure 11As shown, the water tank 901 and track 1001 are installed on the roof. The wire 601 in the hose connector 501 of the water gun is connected to a dedicated power supply. The hose connector 501 is connected to the water tank 901. The moving device 7012 under the mobile fire platform 701 is installed on the track 1001. The third blocking ring 70152 on the two guide grooves 7015 on the mobile fire platform 701 is removed. The hose 301, which is mounted on the conveyor chain 201 to the right of the first blocking ring 2014 on the water gun, is passed through the guide groove 7015 on the rear side of the platform plate 7011. The conveyor chain 201 is inserted into the chain groove 70151 of the guide groove 7015. Lift the water hose 301 upwards and engage the conveyor chain 201 with the drive gear 70131 of the drive device 7013. Extend the water hose 301 forward and engage the conveyor chain 201 with the guide gear 70142 at the end of the telescopic arm 70141 of the telescopic boom device 7014. Pass the water hose 301 downwards through the guide groove 7015 at the end of the telescopic arm 70141. The conveyor chain 201 is engaged in the chain groove 70151 of the guide groove 7015. Place the water hose nozzle 401 at the end of the water gun on the nozzle base 7016 on the platform plate 7011. The two latches 4011 on the water hose nozzle 401 face upwards for easy docking with the drone. Two third blocking rings 70152 are respectively installed on two guide grooves 7015. One end of the wire rope 701431 on the winch 70143 is passed through the hook 70144 below the end of the telescopic boom 70141 and connected to the lifting ring 20151 at the top of the second blocking ring 2015 on the water hose. This completes the installation of the mobile fire platform 701 and the water hose on the top of the high-rise building 801. When the drive gear 70131 rotates forward or backward, the water hose 301 can be conveyed forward or backward via the conveyor chain 201. When the first blocking ring 2014 or the second blocking ring 2015 on the conveyor chain 201 respectively touches the two third blocking rings 70152 on the mobile fire platform 701, the drive gear 70131 stops rotating. This prevents the conveyor chain 201 from falling off the drive gear 70131 and the guide gear 70142.

[0103] The system uses track 1001 as a horizontal reference. It precisely engages the transmission chain 201 within a continuous transmission path formed by the drive gear 70131, guide gear 70142, and chain groove 70151. Combined with the reliable connection between the wire rope 701431 and the lifting ring 20151, a closed-loop force transmission and motion control system is formed. During installation, the design of a detachable third blocking ring 70152 cleverly solves the spatial interference problem of installing long components. The final blocking ring limiting mechanism (the dimensional interference between the first, second, and third blocking rings 70152) constitutes a crucial safety protection, automatically triggering a drive stop at the transmission end to prevent the chain from disengaging. This integrated solution enables the modular and standardized rapid deployment and reliable assembly of high-rise fire protection systems, ensuring precise matching of power transmission, water connections, and electrical connections between subsystems. Through multiple mechanical limits and linkage controls, it provides structural protection for the long-term operational reliability of the entire device in complex high-altitude environments.

[0104] based on Figure 1 The high-rise building fire protection device shown in this embodiment of the invention provides a high-rise building fire protection method.

[0105] Figure 12 A flowchart illustrating a high-rise building fire protection method according to an embodiment of the present invention is shown.

[0106] like Figure 12 As shown, the high-rise building fire protection method according to an embodiment of the present invention includes steps S1 to S6.

[0107] In step S1, the remote-controlled drone flies to the rooftop and docks with the water hose nozzle 401 placed on the nozzle base 7016, locking the drone's locking mechanism with the latch 4011 and connecting the drone's power interface with the charging connector 4012.

[0108] In step S2, the drone carrying the water hose nozzle 401 takes off and hovers in the air outside the building.

[0109] In step S3, the drive device 7013 is started, causing the drive gear 70131 to rotate, which drives the conveyor chain 201 and water hose 301 to be conveyed outward; at the same time, the telescopic arm 70141 is controlled to extend outward, and the winch 70143 is controlled to release the wire rope 701431.

[0110] In step S4, the water hose 301 and the conveyor chain 201 descend under the guidance of gravity and the suspension of the steel wire rope 701431, and the drone descends synchronously until the water hose nozzle 401 reaches the height of the target burning floor.

[0111] In step S5, the mobile fire-fighting platform 701 is controlled to move along track 1001 so that the hovering drone is aimed at the fire point.

[0112] In step S6, the water source of the rooftop water tank 901 is connected through the hose connector 501, and the drone is remotely controlled to operate the hose nozzle 401 to spray water for fire extinguishing.

[0113] In embodiments of the present invention, during firefighting, the spray direction is adjusted by remotely controlling the drone, and / or the drive device 7013 and winch 70143 are synchronized to raise or lower the height of the hose nozzle 401. Because the steel wire rope 701431 suspended on the hook 70144 holds the front end of the hose 301, the weight of the hose 301, the weight of the transmission chain 201, and the weight of the water are basically borne by the steel wire rope 701431 and the transmission chain 201. The drone can easily carry a small section of the end of the hose 301 plus a small amount of water, and can fly freely up, down, left, and right according to the changes in the fire point, thus extinguishing the fire more effectively. When the fire spreads upward, the drive gear 70131 and the winch 70143 rotate inward synchronously, pulling the hose 301 upward, and the drone follows to rise and extinguish the fire.

In particular, the features described in the various embodiments of the present invention can be combined and / or combined in various ways without departing from the spirit and teachings of the present invention. All such combinations and / or combinations fall within the scope of the present invention.
