Description

Technical Field

[0001] This invention relates to the field of high-rise building fire rescue technology, specifically to an automatic connection device and system for supplying water to fire-fighting drones in high-rise buildings, which is particularly suitable for fire fighting in super high-rise buildings over 100 meters. Background Technology

[0002] There are over 5,000 super high-rise buildings in my country that are taller than 100 meters, and high-rise fires have been frequent in recent years. Traditional aerial ladder trucks are generally limited to an operating height of 50-100 meters, making them ineffective against super high-rise buildings over 200 meters.

[0003] Current research primarily focuses on fixed fire suppression systems. Chinese patent CN116870399A discloses an intelligent fire extinguishing device for high-rise buildings, which achieves automatic fire suppression and smoke extraction through fixed sprinkler heads on the floor slab and temperature and smoke sensing systems. However, the sprinkler heads are fixed in position, unable to be flexibly adjusted according to changes in the fire location, and rely on the building's internal power and water supply systems, resulting in poor resilience and inability to handle external wall fires. Regarding mobile fire extinguishing devices, Chinese patent CN215653527U discloses a handcart-type fire extinguishing device for high-rise buildings, using hydraulic cylinders to adjust the sprinkler head height. However, this device is essentially a ground-based device, with a sprinkler head height of only 3-5 meters, rendering it ineffective against high-rise fires, and requiring manual operation, posing a high safety risk in the fire scene. As for ground docking technology, Chinese patent CN113082585B discloses an automatic release device for fire hose connections using a card-type interface, achieving electrically controlled release of the hose connection, but only solving the disconnection problem and not addressing automatic docking. Chinese patent CN114288590B discloses a rapid autonomous docking device for fire hydrant pipes used in firefighting robots. This device achieves automatic docking between a ground-based firefighting robot and a ground-based fire hydrant through a rope traction component and an auxiliary positioning gripper. However, this technology is designed entirely for stable ground environments, and its identification, positioning, gripping mechanisms, and control strategies cannot cope with special conditions such as high-altitude wind disturbances, limited space, and unstable drone hovering.

[0004] Continuous operation of firefighting drones in high-rise building fires presents a significant challenge in terms of water supply. While refuge floors in high-rise buildings possess independent fire-fighting water supply systems, these resources have not yet been utilized to support aerial firefighting drones. There is no technology or equipment capable of automatically docking firefighting drones with refuge floor water supply systems under conditions of high-altitude wind disturbance. Existing ground-based docking technologies cannot be directly applied. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the prior art, such as the limited height for firefighting in super high-rise buildings, difficulties in supplying water to firefighting drones, ineffective utilization of firefighting resources in refuge floors, and the lack of automatic docking technology in high-altitude environments. This invention provides an automatic docking device and system for supplying water to firefighting drones in high-rise buildings. It utilizes an independent fire water supply system and booster pump in the refuge floor to continuously supply water to the hovering firefighting drones, providing a reliable technical solution for efficient firefighting in super high-rise buildings.

[0006] To achieve the above objectives, the present invention provides an automatic connection device and system for supplying water to firefighting drones in high-rise buildings, based on refuge floors, comprising: An automatic docking device, comprising four parts: a capture mechanism, a tube winding mechanism, a flipping mechanism, and a docking mechanism; The mechanical telescopic arm is fixedly installed on the ground of the refuge floor. The mechanical telescopic arm adopts a multi-stage telescopic structure design and can extend from the refuge floor window or reserved opening to the external space of the building. The extension length can be adjusted according to the hovering position of the drone. Booster pumps are used to connect to the fire water pipes in refuge floors, and by boosting the water pressure, a longer water spray distance can be obtained. When the docking device determines the position of the water hose, the capturing mechanism operates. The capturing mechanism employs an active gripping method, and its structure is a clamp-shaped gripper with ball bearings.

[0007] In a preferred embodiment, the capture mechanism includes two staggered clamping arms, each clamping arm having an arc-shaped clamping surface matching the shape of the fire water pipe interface and a wide-range capture surface, wherein multiple balls are located on the wide-range capture surface.

[0008] The clamping arms are driven by a servo motor, enabling them to open and close in an alternating manner. When the fire hose is captured, the hose reeling mechanism clamps the upper end of the fire hose and, via a motor, drives the rollers to rotate, pulling the front end of the fire hose into the positioning port of the clamping mechanism. When the fire hose enters the positioning port, the capturing mechanism locks, securing the fire hose interface with a mechanical locking pin. The fire hose uses a standard plug-in hose; the flipping mechanism flips it, allowing the fire hose outlet to connect with another fire hose placed on the docking mechanism.

[0009] The fire water pipe is placed along the mechanical telescopic arm and can extend and retract with the mechanical arm. The rear end of the fire water pipe is connected to the booster pump through the pipeline system. The booster pump is installed inside the refuge floor, and its inlet is connected to the fire water supply riser or indoor fire hydrant of the refuge floor.

[0010] The system of this invention exhibits a high degree of automation and intelligence in its workflow. When a fire occurs, the fire command center sends a start command to the refuge floor connection device via wireless communication, and simultaneously dispatches a fire-fighting drone to the fire scene. The fire-fighting drone, carrying a fire monitor and a standard fire hose interface, flies to the vicinity of the refuge floor and hovers there. Upon receiving the start command, the refuge floor connection device activates its control system to activate a vision sensor to scan the external space, and quickly locates the hovering drone and its fire hose interface using an image recognition algorithm.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The present invention creatively utilizes the fire protection resources of the refuge floor of high-rise buildings, transforming the refuge floor into a water supply node for aerial firefighting drones. By setting up an automatic connection device and system for supplying water to firefighting drones from high-rise buildings in the refuge floor, the firefighting drones do not need to carry long-distance water hoses from the ground, fundamentally solving the problem of excessive water hose weight limiting the drone's load capacity and maneuverability. At the same time, it significantly reduces the water supply distance, improves firefighting efficiency and the upper limit of operating altitude, and enables firefighting drones to truly have the ability to carry out continuous firefighting operations in super high-rise buildings, filling the technological gap of using refuge floor fire protection resources to support external aerial firefighting equipment.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0014] like Figures 1 to 6 As shown, this invention provides an automatic docking device and system for supplying water to firefighting drones in high-rise buildings. The system mainly includes an automatic docking device 1, a mechanical telescopic arm 2, and a booster pump 3. The entire system is installed inside the refuge floor of the high-rise building, which typically has an independent fire water supply system and power supply.

[0015] The automatic docking device 1 is the core component of the entire system. It is fixedly installed at the front end of the mechanical telescopic arm 2 and extends out of the building from the refuge floor window along with the arm. The automatic docking device 1 comprises four main functional modules: a capture mechanism 11, a hose reel mechanism 12, a flipping mechanism 13, and a docking mechanism 14. These four mechanisms work together sequentially according to the workflow to complete the entire process of automatically identifying, capturing, locating, and docking the fire hose 15 carried by the fire-fighting drone.

[0016] The mechanical telescopic boom 2 adopts a multi-stage telescopic structure design and is fixedly installed on the ground of the refuge floor. Driven by an electric push rod or hydraulic cylinder, it can extend from the fully retracted state to its maximum working length, ensuring that the automatic docking device is 10 meters away from the building facade. The booster pump 3 is installed inside the refuge floor, near the fire water supply riser or indoor fire hydrant. The booster pump's inlet is connected to the fire water supply riser of the refuge floor via a standard fire hose connection, and its outlet is connected to fire hose 15.

[0017] In this embodiment, as Figure 3 As shown, the capture mechanism 11 is responsible for capturing the end interface of the fire hose 15 carried by a hovering fire-fighting drone. The capture mechanism 11 includes a left clamping arm 111 and a right clamping arm 112, which are arranged in an alternating manner and driven to open and close by a first servo motor 116 and a second servo motor 117. The inner sides of both the left clamping arm 111 and the right clamping arm 112 are provided with arc-shaped clamping surfaces. The radius of curvature of the arc-shaped clamping surfaces matches the outer diameter of the standard fire hose interface to ensure a stable contact surface during clamping.

[0018] In this embodiment, as Figure 3 As shown, the outer side of the clamping arm is provided with a wide-range capture surface, on which multiple balls 113 are evenly distributed and can rotate freely. The function of the balls 113 is to guide the fire hose 15 into the clamping area by rolling contact when it approaches, thereby increasing the capture success rate and the margin of error.

[0019] In this embodiment, as Figure 3 As shown, the capturing mechanism 11 is also equipped with a fire hose fixing port 114, which is located at the center position formed when the two clamping arms are closed. When the clamping arms are fully closed, the fixing port firmly clamps the fire hose interface. The clamping fixing plate 115 connects the left clamping arm 111 and the right clamping arm 112, and the first servo motor 116 and the second servo motor 117 are respectively fixedly installed on both sides of the fixing plate 115.

[0020] In this embodiment, as Figure 4 As shown, the hose reel mechanism 12 is the second working unit of the docking device, responsible for further pulling the fire hose 15, which is held by the capture mechanism 11, towards the hose fixing port 114, so that the hose interface accurately enters the predetermined positioning position. The hose reel mechanism 12 includes two sets of symmetrically arranged roller assemblies: roller 121 and drive motor 123 on the left, and roller 122 and drive motor 124 on the right. The two sets of rollers are mounted on the frame formed by the longitudinal fixing plate 1210 and the transverse fixing plate 1211 of the hose reel mechanism via roller fixing plates 125. Drive motors 123 and 124 operate synchronously, driving the fire hose 15 to move.

[0021] In this embodiment, as Figure 4As shown, the hose reel mechanism 12 is also equipped with a blocking leaf 126 and a blocking leaf 127. The blocking leaf is installed below the roller fixing plate 125 and is driven to open and close by a third servo motor 128 and a fourth servo motor 129. The function of the blocking leaf is to flip downwards and block the gap between the roller and the fire hose after the capturing mechanism 11 has finished clamping, so as to prevent the hose from falling off the roller due to positional displacement during the hose reeling process.

[0022] In this embodiment, as Figure 5 As shown, the flipping mechanism 13 is the third working unit of the docking device. It is responsible for flipping the fire hose connector pulled in by the hose reeling mechanism 12 so that the hose connector faces the other fire hose connector pre-installed on the docking mechanism 14, preparing for insertion and docking. The flipping mechanism 13 mainly includes a fifth servo motor 132, a front servo motor mounting plate 131, and a rear servo motor mounting plate 133. The output shaft of the fifth servo motor 132 passes through the front mounting plate 131, driving the capture mechanism to flip.

[0023] In this embodiment, as Figure 6 As shown, the docking mechanism 14 is the last working unit of the automatic docking device, responsible for completing the final insertion and locking of the two fire water pipe interfaces, establishing a stable and reliable water supply channel. The docking mechanism 14 includes a docking mechanism mounting plate 143, a sliding table 144, a telescopic cylinder 146, a fire hose fixing sleeve 141, and related connecting and driving components.

[0024] In this embodiment, as Figure 6 As shown, the docking mechanism mounting plate 143 is used to fix the entire docking mechanism, and the docking mechanism mounting and fire hose fixing plate 148 is used to assist in fixing the docking mechanism and the fire hose 15. The slide 144 is mounted on the guide rail of the fire hose fixing plate 149 and can slide linearly along the guide rail direction.

[0025] The inner diameter of the fire hose fixing sleeve 141 matches the outer diameter of the standard fire hose interface. A section of fire hose interface is pre-installed inside the sleeve. The rear end of the interface is connected to the water supply pipeline attached to the mechanical telescopic arm through a high-pressure water pipe, and finally connected to the booster pump 3.

[0026] The telescopic cylinder 146 uses an electric push rod for pushing and connecting the fire water pipe 15. The servo motor horizontal connecting rod 142 is mounted on the horizontal fixing plate 1211 of the pipe winding mechanism, and the movable end of the electric push rod is connected to the fire water pipe interface sleeve. When the telescopic cylinder 146 receives an extension command, the push rod extends outward to press the fire water pipe interface.

[0027] The flipping mechanism 13 drives the capture mechanism to flip, so that the fire water pipe interfaces are on the same axis. The servo motor 147 is installed on the side of the docking mechanism. The servo motor 147 moves the slide table 144 by cooperating with the servo motor horizontal linkage 142 and the servo motor vertical linkage 145, so that the fire water pipe interface sent by the capture mechanism 11 is pushed into another fire water pipe receiving port. The two interfaces reach the predetermined insertion depth and lock them together.

[0028] The fire hose fixing plate 149 is located at the rear of the docking mechanism and is used to fix and support the water supply pipeline from the booster pump 3. The fire hose sleeve 1410 and the fire water pipe interface sleeve 1411 are arranged in sequence to provide a standardized routing channel and protection for the water supply pipeline.

[0029] The visual recognition system includes a high-definition camera and a depth camera mounted on the front end of the mechanical telescopic arm 2, used to identify the position of the hovering firefighting drone and the fire hose 15 it carries. The control system includes a main controller, a sensor interface module, a drive control module, and a communication module, used to coordinate the operation of the capture mechanism 11, the hose reel mechanism 12, the flipping mechanism 13, the docking mechanism 14, the mechanical telescopic arm 2, and the booster pump 3. The safety protection devices include an emergency stop button, an overload protection circuit, a leakage protection device, and a mechanical limit switch.

[0030] The system workflow is as follows: When a fire breaks out in a high-rise building, upon receiving the alarm, the fire command center immediately sends a start command via wireless communication network to the automatic connection device and system deployed on the corresponding refuge floor, which supplies water to firefighting drones. The mechanical telescopic arm extends the automatic connection device outside the window. Simultaneously, the fire command center dispatches the firefighting drone to take off and fly to the fire scene. The firefighting drone carries a fire monitor and a standard fire hose (15), with a standard fire hose connector installed at the end of the hose.

[0031] After the drone arrives at the designated location near the refuge floor, it hovers outside the safe area of ​​the refuge floor using onboard and visual positioning systems. Upon receiving the activation command, the automatic docking device inside the refuge floor activates the visual recognition system, which quickly identifies the hovering drone and the fire hose 15 it carries using image processing algorithms.

[0032] Upon receiving an opening command, the first servo motor 116 and the second servo motor 117 of the capture mechanism 11 drive the left clamping arm 111 and the right clamping arm 112 to open to their maximum angle. The control system issues a capture command, and the servo motors move rapidly, driving the clamping arms to close towards the center. If there is a deviation in the position of the fire hose 15, the hose first contacts the ball bearings 113 on the outside of the clamping arms, and the ball bearings guide the fire hose to the center of the capture port through rolling contact.

[0033] Once the fire hose 15 enters the center of the capture port, the clamping arms continue to close until the arc-shaped clamping surface is in close contact with the outer surface of the fire hose connector. The control system determines that the capture is successful and locks both clamping arms in the clamped state.

[0034] Upon successful capture, the hose reel mechanism 12 immediately starts. Drive motors 123 and 124 operate synchronously, driving rollers 121 and 122 to rotate. Driven by the rotation of the rollers, the fire hose 15 is pulled, and the fire hose connector moves to the clamping slot position of the flipping mechanism 13.

[0035] After the hose reel mechanism 12 completes its work, the flipping mechanism 13 begins to operate. The fifth servo motor 132 rotates, causing the clamping slot and the fire hose interface to flip together. After the flipping is completed, the opening direction of the fire hose interface is exactly opposite to the opening direction of the fire water pipe interface pre-set on the docking mechanism 14.

[0036] After successful docking, the control system sends a start command to booster pump 3. The booster pump draws water from the fire water supply riser in the refuge floor, and after pressurization, delivers the high-pressure water to the fire hose 15 of the drone, which finally reaches the fire monitor for spraying and extinguishing the fire.

[0037] Throughout the water supply process, the control system continuously monitors the water supply status. Pressure and flow sensors detect pipeline parameters in real time, and the control system dynamically adjusts the speed of the booster pump according to preset strategies to maintain stable water supply pressure and flow.

[0038] When the firefighting mission is completed or the work position needs to be changed, the control system receives a disengagement command. First, it shuts down the booster pump to stop the water supply. After the pipeline pressure drops to a safe value, it releases the lock on the interface, retracts the interface to disengage, the clamping arm opens to release the water pipe interface, and the mechanical telescopic arm retracts into the refuge floor, completing the entire docking and disengagement cycle.

[0039] Finally, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
