Description

Technical Field

[0001] This invention belongs to the field of fire protection equipment technology, and in particular relates to a vertical pole type fire sprinkler system and its fire extinguishing method. Background Technology

[0002] With the acceleration of urbanization, the number of densely packed buildings, such as high-rise and super high-rise residential buildings and "handshake buildings" in urban villages, is increasing, posing a severe challenge to their fire safety. At the same time, complex ground conditions such as riverbanks, waterfronts, gardens, paths, green belts, and dense clusters of buildings further exacerbate the difficulty of firefighting operations, and the multiple shortcomings of traditional fire protection systems are no longer sufficient to meet actual needs.

[0003] Currently, fire trucks are the core equipment for external firefighting in buildings, but their limitations are particularly prominent. First, they are limited by both height and space. The operating height of mainstream aerial ladders is usually no more than 50 meters, which cannot cover the upper part of high-rise residential buildings. In complex ground conditions, fire trucks cannot quickly approach the fire scene, or even enter the work area, and the aerial ladder cannot be set up for operation. Second, there is a contradiction between water supply and consumption. Ground pressurized water supply is affected by gravity and pipeline losses. In high-rise scenarios, "insufficient water pressure and water supply interruption" are prone to occur. Moreover, high-rise firefighting requires high water pressure and high flow rate spraying, resulting in serious water waste and difficulty in maintaining a continuous water supply. Third, there is a high risk to personnel safety. Firefighters need to work close to the building and face threats such as high temperature, dense smoke, and building collapse. The safety protection pressure of external rescue is extremely high. Fourth, the response efficiency is insufficient. Factors such as urban traffic congestion and the time required for equipment deployment cause the response time of fire trucks from receiving the alarm to starting firefighting to generally exceed 15 minutes, missing the golden window of 5-10 minutes after the fire starts. Furthermore, existing firefighting drones are limited by their limited payload and insufficient endurance, making it difficult to achieve sustained firefighting capabilities and unable to independently solve firefighting challenges in high-rise buildings and complex scenarios. Existing supplementary firefighting technologies also have shortcomings. For example, traditional sprinkler systems are mostly applicable to the interiors of public buildings and cannot adapt to the differentiated needs of residential exteriors; various solutions focus on upgrading single equipment or optimizing partial processes, lacking a comprehensive collaborative mechanism encompassing "storage-transportation-reconnaissance-water supply-spraying-maintenance," thus failing to fundamentally address industry pain points. Particularly in the field of exterior building firefighting, there is a lack of a systematic solution that can collaborate with drones, possess rapid deployment capabilities, and offer precise sprinkler control.

[0004] Therefore, it is necessary to provide a vertical pole fire sprinkler system and its fire extinguishing method to address the aforementioned problems in the existing technology. Summary of the Invention

[0005] To address the technical problems in existing technologies, such as fire trucks being limited by building height and ground conditions, fire-fighting drones having insufficient payload and endurance for continuous firefighting, and existing supplementary fire-fighting solutions lacking a full-process coordination mechanism, resulting in slow fire-fighting response, water supply difficulties, and high personnel risks in high-rise and complex scenarios, this invention proposes a vertical pole-type fire sprinkler system and its fire-fighting method to achieve full-process coordinated operation of "storage-transportation-reconnaissance-water supply-spraying-maintenance". Through the cooperation of drones and purely mechanical sprinkler devices, rapid deployment and precise fire extinguishing of the facade of high-rise buildings can be achieved.

[0006] The technical solution of this invention is implemented as follows: a vertical pole type fire sprinkler system, comprising: A vertical pole type sprinkler execution module, which includes a vertical pole type sprinkler device, which is a pure execution mechanism and has no external fire situation autonomous sensing function; The storage and drone dispatch module is used to store the vertical pole sprinkler device under normal conditions and to dispatch a heavy-duty drone to transport the vertical pole sprinkler device when a fire occurs. A fire detection and multi-channel control module is used to simultaneously activate a fire detection drone to collect fire data when a fire occurs, and to generate spraying commands based at least on the fire data; and A multi-source water supply module is used to provide a water source for the vertical pole sprinkler device; The fire detection and multi-channel control module, the storage and drone dispatch module, and the multi-source water supply module are all coordinated with the vertical pole sprinkler execution module. When a fire occurs, the heavy-duty dispatch drone hoists the vertical pole sprinkler device to the facade of the target building, the multi-source water supply module connects to the water source, and the vertical pole sprinkler device executes the spraying fire extinguishing operation according to the spraying command.

[0007] This invention constructs a collaborative system covering the entire process of "storage-transportation-reconnaissance-water supply-spraying-maintenance" to achieve the cooperation between drones and purely mechanical sprinkler devices, breaking through the limitations of building height and ground conditions, shortening the response time to within the golden window for initial fire suppression, and filling the gap in external fire protection technology for high-rise buildings and complex scenarios.

[0008] As a further improvement to the above solution, the vertical rod spraying device includes a vertical rod body, multiple valves and nozzles arranged along the vertical extension direction of the vertical rod body, and a valve control mechanism. The valve control mechanism includes a spray selection mechanism and an opening and closing mechanism. The spray selection mechanism is used to select a target valve from a plurality of valves, and the opening and closing mechanism is used to drive the selected target valve to open or close. The spray selection mechanism includes a spray selection lever and multiple clutches. Each clutch is configured to correspond to a valve. The spray selection lever is provided with multiple spray selection protrusions, each of which corresponds to a clutch. The opening and closing mechanism includes an opening and closing lever, which is connected in a transmission manner to a plurality of the clutches; When the spray selector lever moves to the point where one of the spray selector protrusions abuts against the corresponding clutch, the clutch switches to the engaged state, establishing a transmission relationship between the corresponding valve and the opening / closing lever. The reciprocating motion of the opening / closing lever drives the valve to open or close.

[0009] It adopts a purely mechanical selection structure that combines a spray nozzle protrusion with a clutch, replacing the traditional solenoid valve solution. It can achieve precise selection and opening / closing of the target valve without the need for electronic sensors. The structure is simple and reliable, effectively resisting high temperatures, dense smoke and electromagnetic interference in the fire scene, and ensuring operational stability.

[0010] As a further improvement to the above solution, the vertical pole sprinkler system also includes a fixed-distance bracket. This bracket is located in the middle section of the vertical pole body and is used to maintain a constant distance between the vertical pole body and the building facade when the vertical pole sprinkler system is suspended from the roof railing for operation. Maintaining a constant distance between the vertical pole body and the building facade through the fixed-distance bracket ensures consistency in the spray angle and coverage area of ​​the sprinkler heads, avoids blind spots or water pressure loss due to distance fluctuations, and improves fire extinguishing accuracy and water resource utilization.

[0011] As a further improvement to the above solution, the vertical pole sprinkler device also includes a hanging bracket, which is located at the upper end of the vertical pole body and is used to hang the vertical pole sprinkler device on the roof railing or to dock with the heavy-duty transport drone. The hanging support includes a main frame, a wheel system, and lifting lugs; the wheel system is mounted on the main frame and is used to drive the vertical spray device to move laterally along the roof railing; the lifting lugs are high-strength load-bearing structures and are used to perform purely mechanical geometric constraint docking with the heavy-duty transport drone.

[0012] The hanging bracket integrates a walking wheel system and lifting lugs, which can move laterally along the roof railing to cover different work areas, and can also be docked with heavy-duty transport drones with pure mechanical geometric constraints to realize dual-mode operation of "roof hanging" and "drone hanging", adapting to various complex building structures.

[0013] As a further improvement to the above solution, at least one positioning mark is provided on the outer side of the vertical rod body at a position corresponding to each of the nozzles. The code of the positioning mark corresponds one-to-one with the nozzle serial number and is used for the fire reconnaissance drone to identify and determine the position of the target nozzle. The fire reconnaissance drone is configured to: upon detecting a fire on a building facade, simultaneously identify the location marker and transmit wireless data containing the fire location and corresponding location marker code information to the fire reconnaissance and multi-channel control module to generate a spraying command containing the target sprinkler head opening and closing instructions. By mapping the location marker code to the sprinkler head serial number, the fire reconnaissance drone can accurately identify the fire location and generate the target sprinkler head opening and closing instructions, achieving precise point-to-point fire suppression and avoiding water waste and secondary water loss caused by ineffective spraying.

[0014] As a further improvement to the above solution, the storage and drone delivery module adopts a cellular distributed layout, using regular hexagons as the basic unit to divide the protected area; the vertical pole sprinkler device is normally suspended vertically on the roof load-bearing structure of the building via its hanging bracket; the heavy-duty delivery drone is configured to start synchronously with the fire reconnaissance drone, plan the delivery route according to the fire data, dock with the vertical pole sprinkler device through image recognition, and complete the delivery. By adopting a cellular distributed layout and pre-dock storage mode, the heavy-duty delivery drone starts synchronously with the fire reconnaissance drone, significantly shortening the device delivery time, enabling rapid delivery in the early stages of a fire, and improving the overall system response efficiency and area coverage capability.

[0015] As a further improvement to the above solution, the multi-source water supply module includes a water source adaptation unit and an emergency water supply pump sub-module. The water source adaptation unit is compatible with legal fire-fighting water on the top floor, non-legal high-level water sources on the roof, water supply across adjacent buildings, and ground-level water supply, and selects or prompts for water sources according to priority. The emergency water supply pump submodule adopts an integrated design of pipeline pump and small booster pump, and is configured to automatically switch between low-pressure relay boosting mode and medium-lift emergency mode according to the water supply pressure.

[0016] The multi-source water supply is compatible with four types of water sources and automatically selects them according to priority. The emergency water supply pump automatically switches between two modes, effectively solving the problem of insufficient water pressure in high-rise buildings, ensuring continuous and stable water supply, while reducing water waste and improving water supply reliability.

[0017] As a further improvement to the above solution, the fire detection and multi-channel control module includes the fire detection drone, a dedicated communication link, and a multi-channel control unit; The fire reconnaissance drone is equipped with infrared detection and real-time image transmission capabilities; The multi-channel control unit includes an automatic command mode, a manual intervention mode, and an emergency adjustment mode. In the automatic command mode, the command platform generates sprinkler commands based on fire reconnaissance data. The manual intervention mode allows authorized personnel to adjust sprinkler parameters via mobile terminals. The emergency adjustment mode supports remote command issuance from the fire command base station. By simultaneously employing these three modes, the system ensures efficient automated operations while retaining flexibility for human intervention in complex scenarios, enhancing its fault tolerance and on-site adaptability, and ensuring foolproof fire response.

[0018] A fire extinguishing method applied to the vertical pole type fire sprinkler system as described above includes the following steps: S1. After a fire is triggered, a fire reconnaissance drone is simultaneously launched to collect data on the fire point, and a heavy-duty transport drone is dispatched to the storage point to retrieve the vertical pole sprinkler device. S2. The fire reconnaissance drone will transmit the collected fire point data back to the command platform, and the heavy-duty transport drone will deliver the vertical pole sprinkler device to the working position on the roof of the target building according to the instructions. S3. Connect the multi-source water supply module to the vertical pole sprinkler device according to the water source priority, and confirm that the water supply meets the standards. S4. The command platform generates a spraying command based on the fire point data and sends it to the vertical rod spraying device. The spray selection mechanism of the vertical rod spraying device selects the target valve according to the command, and the opening and closing mechanism drives the target valve to open, so that the corresponding nozzle is aimed at the fire point to spray and extinguish the fire. S5. After the fire is extinguished, the vertical pole sprinkler system is retrieved and maintenance records are made.

[0019] By simultaneously initiating reconnaissance and transportation, connecting water sources according to priority, and selecting target valves for opening and closing in a standardized process, seamless connection is achieved in all aspects of fire response, forming a closed loop from fire triggering to operation completion, thereby improving overall fire extinguishing efficiency.

[0020] As a further improvement to the above solution, S4 specifically includes: When the fire reconnaissance drone detects a fire on the building facade, it simultaneously identifies the positioning marks that correspond one-to-one with the nozzles on the outside of the vertical pole body, and obtains the coding information corresponding to the target nozzle that matches the height of the fire point. The positioning marks are geometric codes or specific graphics, and their codes correspond one-to-one with the nozzle serial numbers. The fire reconnaissance drone transmits wireless data containing the location of the fire point and the coded information to the command platform. The command platform matches the corresponding target nozzles according to the coded information and generates a spraying command containing the opening and closing instructions of the target nozzles. After receiving the spraying command, the vertical rod spraying device drives the spraying rod to move through the spraying drive unit, so that the spraying protrusion on the spraying rod moves to the clutch position corresponding to the target nozzle. The spraying protrusion pushes the clutch moving component to overcome the elastic force of the elastic component, so that the clutch switches from the disengaged state to the engaged state. The opening and closing drive unit drives the opening and closing lever to reciprocate, and through the engaged clutch, it drives the corresponding valve core to rotate, so that the target valve opens and the corresponding nozzle starts spraying to extinguish the fire. When the water supply pressure is below the rated value, all sprinkler heads remain closed, and the sprinkler system will automatically start once the water pressure reaches the standard.

[0021] By refining the timing of mechanical actions such as positioning mark recognition, code matching, engagement of the selective spray protrusion drive clutch, and rotation of the valve core driven by the opening and closing lever, and combining water pressure detection with delayed start-up, accurate selection and safe spraying are ensured, avoiding ineffective operation due to low water pressure.

[0022] Beneficial effects: (1) Breaking through the limitations of building height and ground conditions to achieve rapid response to fires in all scenarios: This invention achieves rapid response to fires in all scenarios by simultaneously starting and coordinating the storage and drone dispatch module, the fire detection and multi-channel control module, and the division of labor and cooperation between the heavy-duty dispatch drone and the fire detection drone. The fire detection drone first approaches to collect fire data, and the heavy-duty dispatch drone simultaneously dispatches the vertical pole sprinkler device. This completely gets rid of the limitations of traditional fire trucks on complex ground conditions such as ladder height, narrow streets and alleys, and riverbanks. It can cover fires in the upper part of high-rise residential buildings and areas that fire trucks cannot enter, such as "handshake buildings" in urban villages. The response time is shortened from more than 15 minutes for traditional fire trucks to within the golden window for initial fire suppression, thus achieving early suppression of fires.

[0023] (2) Pure mechanical actuators improve the reliability and safety of fire scene operations: As a pure actuator, the vertical rod sprinkler device has no external fire situation autonomous sensing function. Its internal pure mechanical transmission method, which uses the spray selection protrusion and clutch to realize the valve opening and closing on demand, does not rely on electronic sensors and solenoid valves, which are easily affected by the high temperature, dense smoke and electromagnetic interference of the fire scene. It can operate stably in harsh fire scene environments. At the same time, firefighters only need to complete auxiliary work such as water supply connection in the safe area on the roof. They do not need to approach the fire scene to face the high temperature, dense smoke and building collapse risk, which greatly reduces the safety hazards to personnel.

[0024] (3) Multi-source priority water supply ensures the stability and water-saving efficiency of high-rise water supply: This invention uses a multi-source water supply module to be compatible with four types of water sources: legal fire water on the top floor, non-legal high-level water source on the roof, water supply across adjacent buildings, and ground bottom water supply. It selects high-level water sources according to priority order, makes full use of natural gravity water supply, and effectively solves the industry problem of "insufficient water pressure and water supply interruption" in high-rise buildings. At the same time, the vertical pole sprinkler device adopts a precise sprinkler mode close to the building facade, which does not require high water pressure and high flow for long-distance spraying, significantly improving the water resource utilization rate and avoiding the water resource waste caused by long-distance spraying of traditional fire trucks.

[0025] (4) Full-process collaborative closed loop fills the gap in residential external fire protection technology: The present invention constructs a full-process collaborative operation system of "storage-transportation-reconnaissance-water supply-sprinkler-operation and maintenance". Each module interacts with information in real time through a dedicated communication link, forming a seamless connection from fire triggering to operation completion; the vertical pole sprinkler device is normally suspended vertically on the roof load-bearing structure and pre-connected with the lifting lug of the heavy-duty transport drone. It can be quickly deployed without on-site assembly when a fire occurs, providing a complete and reliable external fire extinguishing solution for traditional fire blind spots such as high-rise residential buildings, super high-rise apartments, "handshake buildings" in urban villages and buildings around riverbanks, with significant engineering application value and promotion prospects.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In the description of this invention, it should be understood that the term "a number" means "at least one", and the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0029] Example: like Figures 1-9 As shown, this embodiment provides a vertical pole type fire sprinkler system, including: A vertical pole type sprinkler execution module, which includes a vertical pole type sprinkler device, which is a pure execution mechanism and has no external fire situation autonomous sensing function; The storage and drone dispatch module is used to store the vertical pole sprinkler device under normal conditions and to dispatch a heavy-duty drone to transport the vertical pole sprinkler device when a fire occurs. A fire detection and multi-channel control module is used to simultaneously activate a fire detection drone to collect fire data when a fire occurs, and to generate spraying commands based at least on the fire data; and A multi-source water supply module is used to provide a water source for the vertical pole sprinkler device; The fire detection and multi-channel control module, the storage and drone dispatch module, and the multi-source water supply module are all coordinated with the vertical pole sprinkler execution module. When a fire occurs, the heavy-duty dispatch drone hoists the vertical pole sprinkler device to the facade of the target building, the multi-source water supply module connects to the water source, and the vertical pole sprinkler device executes the spraying fire extinguishing operation according to the spraying command.

[0030] The modules mentioned above interact with each other via dedicated communication links, which include, but are not limited to, fire-specific wireless communication networks, 4G / 5G mobile communication networks, or fire command base station communication links.

[0031] In this embodiment, the vertical pole sprinkler system includes a vertical pole body, multiple valves and nozzles arranged along the vertical extension direction of the vertical pole body, and a valve control mechanism. The vertical pole body extends vertically, and the protective outer shell of the vertical pole body can have a diameter of 200mm. It has a main water pipe inside, and several horizontal branch pipes extend from the side wall of the main water pipe toward the side wall of the vertical pole body. The valves and nozzles are respectively installed on the horizontal branch pipes. The vertical pole sprinkler system is made of lightweight, high-strength, fire-resistant and high-temperature resistant materials, and is produced in a standardized manner according to building height specifications (32m / 48m class), with a length-to-diameter ratio of 1:160 / 1:240, which is suitable for fire fighting needs of different building heights.

[0032] The valve control mechanism includes a spray selection mechanism and an opening and closing mechanism. The spray selection mechanism is used to select a target valve from a plurality of valves, and the opening and closing mechanism is used to drive the selected target valve to open or close. The spray selection mechanism includes a spray selection lever and multiple clutches. Each clutch is configured to correspond to a valve. The spray selection lever is provided with multiple spray selection protrusions, each of which corresponds to a clutch. The opening and closing mechanism includes an opening and closing lever, which is connected in a transmission manner to a plurality of the clutches; When the selective spray lever moves to the point where one of the selective spray protrusions abuts against the corresponding clutch, the clutch engages, establishing a transmission relationship between the corresponding valve and the opening / closing lever. The reciprocating motion of the opening / closing lever drives the valve to open or close. This purely mechanical selection structure, employing a selective spray protrusion and clutch, replaces the traditional solenoid valve solution. It achieves precise selection and opening / closing of the target valve without the need for electronic sensors. The structure is simple and reliable, effectively resisting high temperatures, dense smoke, and electromagnetic interference in a fire, ensuring operational stability.

[0033] Specifically, the top of the vertical spraying device is equipped with a control cabin, which contains a selective spray drive unit and an opening / closing drive unit. The selective spray drive unit is tractively connected to the selective spray lever and is used to drive the selective spray lever to move vertically. The opening / closing drive unit is tractively connected to the opening / closing lever and is used to drive the opening / closing lever to reciprocate vertically. The selective spray drive unit and the opening / closing drive unit can be stepper motors or servo motors to achieve precise displacement control.

[0034] Specifically, the valve includes a valve body and a valve core disposed within the valve body, the valve core comprising a round shaft section and a square shaft section; the clutch includes a clutch lever, a clutch actuator, and an elastic element, the clutch lever being sleeved on the round shaft section of the valve core, the clutch actuator being sleeved on the square shaft section of the valve core and circumferentially synchronized with it, and the elastic element abutting between the clutch lever and the clutch actuator, so that the clutch is always in a disengaged state; the selective spray protrusion is disposed on the side where the clutch actuator is located, and when the selective spray lever moves to make the selected spray protrusion... When the selected spray protrusion abuts against the clutch actuator, the protrusion pushes the clutch actuator to overcome the elastic force of the elastic element and move along the axial direction of the valve core, causing the clutch actuator to engage with the clutch rocker arm. The opening / closing lever is connected to the clutch rocker arm. After the clutch actuator engages with the clutch rocker arm, the reciprocating motion of the opening / closing lever drives the clutch actuator to swing through the clutch rocker arm. The clutch actuator drives the valve core to rotate through the square shaft section of the valve core, thereby realizing the opening and closing of the corresponding valve. The elastic element is preferably a compression spring or a tower spring, and its elastic coefficient is set according to the reset requirements of the clutch actuator. The engagement surface of the clutch actuator and the clutch rocker arm can be provided with mutually cooperating concave and convex structures, such as teeth or friction surfaces, to enhance transmission reliability.

[0035] In this embodiment, the vertical pole sprinkler system further includes a distance-fixing bracket located in the middle section of the vertical pole body. This bracket ensures a constant distance between the vertical pole body and the building facade when the sprinkler system is suspended from the roof railing. Maintaining a constant distance between the vertical pole body and the building facade ensures consistency in the spray angle and coverage area, preventing blind spots or water pressure loss due to distance fluctuations, and improving fire extinguishing accuracy and water resource utilization. Specifically, the distance-fixing bracket includes a retractable swing arm and distance-fixing wheels at the end of the swing arm. When the bracket is extended, the distance-fixing wheels contact the building facade, maintaining a constant distance between the vertical pole body and the building facade. When the bracket is retracted, it reduces the space occupied by the device and facilitates transport. The distance-fixing bracket also includes a distance-fixing drive motor and a transmission mechanism. The distance-fixing drive motor drives the swing arm to extend or retract via the transmission mechanism. The transmission mechanism can be a worm gear mechanism or a rack and pinion mechanism to achieve a self-locking function and prevent the swing arm from accidentally retracting during operation.

[0036] In this embodiment, the vertical pole sprinkler system further includes a hanging bracket, which is located at the upper end of the vertical pole body and is used to suspend the vertical pole sprinkler system on the roof railing or dock with the heavy-duty transport drone. The hanging bracket includes a main frame, a wheel system, and lifting lugs. The wheel system is located on the main frame and is used to drive the vertical pole sprinkler system to move laterally along the roof railing. The lifting lugs are high-strength load-bearing structures used to hook with the heavy-duty transport drone for purely mechanical geometric constraint docking. The hanging bracket integrates the wheel system and lifting lugs, allowing it to move laterally along the roof railing to cover different work areas, and also to dock with the heavy-duty transport drone using purely mechanical geometric constraint docking, realizing dual-mode operation of "rooftop suspension" and "drone suspension," adapting to various complex building structures.

[0037] Specifically, the walking wheel system includes a drive wheel, a load-bearing wheel, an inner wheel, and an adjusting wheel. The drive wheel is driven by a walking drive motor. The inner wheel cooperates with the adjusting wheel to maintain force balance and posture stability when the sprinkler device is suspended from the roof railing. The hanging bracket also includes a posture adjustment bracket, used to adjust the parallelism between the vertical pole body and the building facade in real time to ensure a constant spacing. The posture adjustment bracket can adopt a screw adjustment mechanism or a parallelogram linkage mechanism, driven by a posture adjustment motor, to keep the adjusting wheel in contact with the outer wall of the roof railing, thereby dynamically adjusting the verticality of the vertical pole body.

[0038] In this embodiment, at least one positioning mark is provided on the outer side of the vertical rod body at a position corresponding to each of the nozzles. The code of the positioning mark corresponds one-to-one with the nozzle serial number and is used for the fire reconnaissance drone to identify and determine the position of the target nozzle. The fire reconnaissance drone is configured to: upon detecting a fire on a building facade, simultaneously identify the location marker and transmit wireless data containing the fire location and corresponding location marker code information to the fire reconnaissance and multi-channel control module to generate a spraying command containing the target sprinkler head opening and closing instructions. By mapping the location marker code to the sprinkler head serial number, the fire reconnaissance drone can accurately identify the fire location and generate the target sprinkler head opening and closing instructions, achieving precise point-to-point fire suppression and avoiding water waste and secondary water loss caused by ineffective spraying.

[0039] In this embodiment, the positioning identifier is a machine-recognizable geometric code or specific graphic. The geometric code includes barcodes, QR codes, or 3D codes, and the specific graphic includes circles, squares, triangles, trapezoids, or rings. The 3D code adopts a matrix structure, with matrix holes machined on a slotted thin plate. The slotted plate is then fastened to the surface of the vertical rod body, and its installation height and spacing correspond one-to-one with the nozzles. The encoding identification uses binary, octal, hexadecimal, or 32-bit binary, and nozzle position identification and numbering are achieved through multi-digit combination. Preferably, a 2×6 matrix structure 3D code is used, with start and end codes at the beginning and end, and a 2×4 information code in the middle. The encoding sequence number is fixed from top to bottom.

[0040] In this embodiment, the storage and drone dispatch module adopts a cellular distributed layout, with regular hexagons as the basic unit to divide the protection area; the vertical pole sprinkler device is normally suspended vertically on the roof load-bearing structure of the building through its hanging bracket; the heavy-duty dispatch drone is configured to: start synchronously with the fire reconnaissance drone, plan the dispatch route according to the fire data, and dock with the vertical pole sprinkler device through image recognition to complete the delivery.

[0041] Specifically, the storage and drone delivery module includes a storage submodule and a heavy-duty delivery drone. The storage submodule adopts a honeycomb distributed layout, dividing urban and rural building protection areas into hexagonal units. A storage point is located at the center of each unit. Vertical pole sprinkler systems are suspended from the building's rooftop load-bearing structure via lugs and pre-filled with water. The heavy-duty delivery drone connects to the lugs of the vertical pole sprinkler system via hooks to complete the delivery, calibrating its position using drone positioning data and its own image recognition function. The storage point is equipped with fencing and safety protection facilities, and is equipped with water pressure sealing testing equipment for periodically testing the sealing performance of the vertical pole sprinkler system. The heavy-duty delivery drone is wind-resistant, and its maximum takeoff weight is not less than the total weight of the vertical pole sprinkler system fully loaded with water.

[0042] In this embodiment, the multi-source water supply module includes a water source adaptation unit and an emergency water supply pump sub-module; The water source adaptation unit is compatible with legal fire-fighting water on the top floor, non-legal high-level water sources on the roof, water supply across adjacent buildings, and ground-level water supply, and selects or prompts for water sources according to priority. The multi-source water supply module is responsible for providing a stable top-down water supply link for the vertical pole sprinkler system. It is compatible with various on-site water source conditions, including four types of water sources: legal fire water on the top floor, non-legal high-level water source on the roof, water supply across adjacent buildings, and ground-level water supply. It is equipped with quick-connect connectors (standardized quick connectors, flexible sealing interfaces, standard fire hose connectors, etc.) to achieve rapid switching and access of water sources without the need for complicated pretreatment processes. The water source selection follows the core design principles of "high-level priority, emergency backup, innovative cross-building, and national standard compatibility," configuring four water connection methods in order of reliability and response efficiency. The top-floor legally mandated fire water connection point (stairwell / corridor) is the optimal choice, relying on the mandatory configuration requirements of the "Code for Fire Protection Design of Buildings," ensuring 100% deployment certainty and enabling rapid water supply without pressurization; the non-legally mandated high-level water source on the roof is the second-best choice, with a flexible sealing design at the interface to adapt to different specifications of water outlets; emergency water supply across adjacent buildings is achieved by using drones to pull guide ropes, pull load-bearing cables, and use water supply pipeline loops (force separation) to overcome spatial limitations; ground-level emergency backup water supply is an alternative, supporting connections to municipal fire pipe networks, natural water sources, and fire truck water sources, meeting water pressure requirements through high-pressure emergency pumps or fire truck-mounted booster systems.

[0043] The emergency water supply pump submodule adopts an integrated design of pipeline pump and small booster pump, and is configured to automatically switch between low-pressure relay boosting mode and medium-lift emergency mode according to the water supply pressure. Multi-source water supply is compatible with four types of water sources and automatically selects them according to priority. The emergency water supply pump automatically switches between dual modes, effectively solving the problem of insufficient water supply pressure in high-rise buildings, ensuring continuous and stable water supply, while reducing water waste and improving water supply reliability.

[0044] Specifically, the water source adaptation unit is equipped with quick-connect couplings. For cross-building water supply between adjacent buildings, a drone-guided traction rope, a load-bearing cable with spaced loops, and a stress-separated design for the water supply pipeline passing through the loops are used. Ground-level water supply supports connections to municipal fire-fighting networks, natural water sources, and fire truck water sources, meeting water pressure requirements through emergency water pumps or fire truck-mounted booster systems. The emergency water pump submodule adopts an integrated lightweight enclosure structure, powered by a combination of a high-capacity lithium battery pack and a pure sine wave inverter, with built-in multiple safety protection mechanisms including water shortage detection, motor overload, and low battery warning. The water supply execution unit uses high-pressure wear-resistant rubber hoses, allowing water supply to be turned on and off as needed based on the on-site water source and sprinkler requirements. The quick-connect couplings use standard fire-fighting interface specifications, such as DN50 or DN65, to ensure compatibility with existing fire-fighting facilities. The low-pressure relay booster mode is suitable for scenarios where the water supply pipeline pressure is insufficient but there is still water flow, while the medium-lift emergency mode is suitable for scenarios requiring direct water supply from the ground to high-rise buildings. The two modes are automatically switched through a frequency converter control system.

[0045] In this embodiment, the fire detection and multi-channel control module includes the fire detection drone, a dedicated communication link, and a multi-channel control unit; The fire reconnaissance drone is equipped with infrared detection and real-time image transmission capabilities; The multi-channel control unit includes an automatic command mode, a manual intervention mode, and an emergency adjustment mode. In the automatic command mode, the command platform generates sprinkler commands based on fire reconnaissance data. The manual intervention mode allows authorized personnel to adjust sprinkler parameters via mobile terminals. The emergency adjustment mode supports remote command issuance from the fire command base station. By simultaneously employing these three modes, the system ensures efficient automated operations while retaining flexibility for human intervention in complex scenarios, enhancing its fault tolerance and on-site adaptability, and ensuring foolproof fire response.

[0046] In this embodiment, the fire reconnaissance drone is lightweight and independent of heavy-duty transport drones, allowing it to approach safe areas surrounding the fire scene and accurately identify the burning floor, fire location, and spread trend. The dedicated communication link integrates a dedicated fire-fighting internet platform, a mobile internet platform, and a fire command base station, enabling real-time data transmission and efficient command issuance. The manual intervention mode requires authorized personnel with dual authentication to manually adjust sprinkler parameters and device movement status via a dedicated mobile terminal based on the reconnaissance footage. The dual authentication includes identity authentication and device authentication. Identity authentication can use digital certificates or biometric identification, while device authentication can use hardware encryption chips or device serial number binding.

[0047] This embodiment also provides a fire extinguishing method for a vertical pole fire sprinkler system, including the following steps: S1. After a fire is triggered, a fire reconnaissance drone is simultaneously launched to collect data on the fire point, and a heavy-duty transport drone is dispatched to the storage point to retrieve the vertical pole sprinkler device. S2. The fire reconnaissance drone will transmit the collected fire point data back to the command platform, and the heavy-duty transport drone will deliver the vertical pole sprinkler device to the working position on the roof of the target building according to the instructions. S3. Connect the multi-source water supply module to the vertical pole sprinkler device according to the water source priority, and confirm that the water supply meets the standards. S4. The command platform generates a spraying command based on the fire point data and sends it to the vertical rod spraying device. The spray selection mechanism of the vertical rod spraying device selects the target valve according to the command, and the opening and closing mechanism drives the target valve to open, so that the corresponding nozzle is aimed at the fire point to spray and extinguish the fire. S5. After the fire is extinguished, the vertical pole sprinkler system is retrieved and maintenance records are made.

[0048] Furthermore, S4 specifically includes: When the fire reconnaissance drone detects a fire on the building facade, it simultaneously identifies the positioning marks that correspond one-to-one with the nozzles on the outside of the vertical pole body, and obtains the coding information corresponding to the target nozzle that matches the height of the fire point. The positioning marks are geometric codes or specific graphics, and their codes correspond one-to-one with the nozzle serial numbers. The fire reconnaissance drone transmits wireless data containing the location of the fire point and the coded information to the command platform. The command platform matches the corresponding target nozzles according to the coded information and generates a spraying command containing the opening and closing instructions of the target nozzles. After receiving the spraying command, the vertical rod spraying device drives the spraying rod to move through the spraying drive unit, so that the spraying protrusion on the spraying rod moves to the clutch position corresponding to the target nozzle. The spraying protrusion pushes the clutch moving component to overcome the elastic force of the elastic component, so that the clutch switches from the disengaged state to the engaged state. The opening and closing drive unit drives the opening and closing lever to reciprocate, and through the engaged clutch, it drives the corresponding valve core to rotate, so that the target valve opens and the corresponding nozzle starts spraying to extinguish the fire. When the water supply pressure is below the rated value, all sprinklers remain closed, and the sprinkler system automatically starts spraying once the water pressure reaches the standard. The rated value of the water supply pressure can be preset according to the building height and sprinkler type. The water pressure compliance detection can be achieved through a pressure sensor installed at the water inlet pipe of the vertical rod sprinkler device. When the water pressure is detected to reach the rated value, the control room automatically sends a start signal to the start / stop drive unit.
