Abstract
Description
Technical Field
[0001] This invention relates to the field of fire rescue equipment technology, and in particular to an airborne fire extinguishing pod system and fire extinguishing method suitable for high-rise buildings. Background Technology
[0002] With the increasing number of high-rise buildings, the demand for high-altitude, long-distance firefighting capabilities in fire accidents is becoming increasingly prominent. In reality, aside from drills and demonstrations, there are currently no feasible and effective solutions for firefighting in high-rise buildings. Traditional firefighting equipment is limited by factors such as operating height, deployment conditions, and personnel safety, making it difficult to meet the rapid response requirements of high-rise fires. Therefore, utilizing drones for firefighting operations has become one of the research and application directions in recent years.
[0003] Existing drone firefighting devices generally suffer from drawbacks such as insufficient altitude, small liquid capacity, inability to continuously supply water, difficulty in sealing telescopic spray guns leading to water leakage, large wind disturbances, and difficulty in approaching the fire scene, making it impossible to achieve truly practical high-rise firefighting.
[0004] The existing technology has the following main drawbacks: 1. The number of aerial ladder trucks and access platforms is limited, generally only reaching 50-100m, and cannot cover high-rise buildings of 250m and above; 2. Existing drone firefighting devices have limited liquid capacity and short flight time, making it impossible to provide continuous water supply; 3. Long-distance telescopic spray guns generally use dynamic sealing structures, which are prone to leakage, jamming, and wear under high pressure, resulting in extremely low reliability; 4. The vertical water conveyance system is greatly affected by gravity, and long-distance water hoses are prone to tearing, tensile deformation, and wind-induced twisting; 5. Traditional drones operating near fire scenes are easily affected by hot air currents, dense smoke, and deflagration, resulting in extremely low safety.
[0005] 6. Most drones cannot be equipped with compressed air foam systems due to their large size, heavy weight, and strong vibration.
[0006] Therefore, existing technologies cannot achieve a complete fire extinguishing closed loop that ensures continuous water supply, precise dry foam spraying, high reliability, and high safety for 250m high-rise buildings. Summary of the Invention
[0007] In order to overcome the problems existing in the prior art, the purpose of this invention is to provide an airborne fire extinguishing pod system and fire extinguishing method for ultra-high-rise buildings. It aims to break through the bottleneck of UAV fire extinguishing in ultra-high-rise buildings, and achieve continuous water supply, high efficiency and safety of high-level fire extinguishing operations by solving the problems of water pipeline load-bearing and vibration, innovating the spray structure and carrying fire extinguishing units.
[0008] To achieve the above objectives, an airborne fire extinguishing pod system for ultra-high-rise buildings is provided, comprising a heavy-duty drone and a fire extinguishing pod, wherein the fire extinguishing pod can be quickly installed and disassembled under the heavy-duty drone; The fire extinguishing pod is equipped with a telescopic nozzle assembly below it, and the fire extinguishing pod and the telescopic nozzle assembly are connected by an deployment mechanism; The deployment mechanism can extend the telescopic nozzle assembly downwards and forwards in parallel to reduce recoil. An angle adjuster is provided between the fire extinguishing pod and the telescopic nozzle assembly. The angle adjuster is used to adjust the angle of the horizontal attitude of the telescopic nozzle assembly. This can increase the safe distance between the drone and the fire site. When the nozzle is extended, the fire extinguishing range can be extended by adjusting the angle, while keeping the drone's attitude stable.
[0009] The fire extinguishing pod is equipped with a fire extinguishing unit, which is one of the following: a water-based fire extinguishing agent unit, a compressed air foam fire extinguishing agent unit, a hydrogel-type fire extinguishing agent unit, a dry powder fire extinguishing agent unit, a liquid nitrogen dry powder fire extinguishing agent unit, or a liquid nitrogen foam fire extinguishing agent unit. Each fire extinguishing unit is equipped with a spray pipe. Different fire extinguishing units can be selected to flexibly handle and control the fire situation according to different fire conditions.
[0010] The telescopic nozzle assembly is equipped with a telescopic nozzle, which is a multi-section telescopic sleeve structure with different thicknesses. The outer layer of the telescopic nozzle is a square nozzle, and the inner layer is a round nozzle. A spray gun is connected to the front end of the round nozzle, and a nozzle head is provided at the front end of the spray gun. The square nozzle has good support, while the round nozzle has good flexibility. When the fire is large, the temperature next to the building is too high. Only when there is a sufficient distance can drones and firefighting operations be safe.
[0011] The fire extinguishing pod is equipped with a turntable in front, and a steel wire rope is wound up on the turntable. The front ends of the steel wire rope are symmetrically arranged on both sides of the telescopic nozzle and fixed to the front end of the nozzle. The steel wire rope has a pulling effect, which can keep the nozzle stable in the up, down and left and right directions during fire extinguishing operations. The spray nozzle is connected to the rear end of the telescopic spray nozzle; The fire extinguishing pod is equipped with support legs on all four sides for easy storage. The fire extinguishing pod is also equipped with a control system for controlling the fire extinguishing unit, the deployment mechanism, and the angle adjuster; It also includes a handheld remote control that can be adapted to the control system.
[0012] Furthermore, the deployment mechanism includes a connecting rod and a lifting motor. The lifting motor is located below the front end of the fire extinguishing pod. One end of the connecting rod is connected to the output shaft of the lifting motor, and the other end is movably connected to the telescopic nozzle assembly. The angle adjuster includes a lead screw, a lead screw nut, and a drive motor. The drive motor is located in the lower middle part of the fire extinguishing pod. The telescopic nozzle assembly has a lead screw nut at its end. One end of the lead screw is connected to the drive motor, and the other end is movably connected to the lead screw nut. The deployment mechanism and the angle adjuster are respectively adjacent linkage mechanisms, which together with the fire extinguishing pod and the telescopic nozzle assembly form a parallelogram mechanism. The deployed parallelogram can reduce recoil and play a buffering role. Preferably, the fire extinguishing unit is a water-based fire extinguishing agent fire extinguishing unit, including a fire pump, a water-based fire extinguishing agent storage tank, and a spray hose reel, wherein the spray hose is connected to the fire pump; the fire pump delivers water-based fire extinguishing agent from the water-based fire extinguishing agent storage tank to the spray hose.
[0013] Preferably, the fire extinguishing unit is a foam liquid fire extinguishing agent unit, including a water supply unit, an air supply unit, a foam liquid tank, a foam liquid pump, a spray hose reel, and a mixer. The water supply unit includes a fire pump, a buffer tank, and a hanging water delivery assembly. The hanging water delivery assembly includes a hose reel and a water supply hose. The end of the water supply hose is connected to a high-lift submersible pump to prevent the water hose from bursting due to high pressure. The front end of the water supply hose is connected to the buffer tank. The air supply unit includes a solenoid valve, a pressure regulating valve, an air tank, and an air compressor. The mixer is connected to the foam liquid tank, the water supply unit, and the air supply unit. The control system controls the mixer to mix the foam liquid, water, and air in proportion and deliver them to the telescopic spray nozzle assembly through the spray hose.
[0014] Furthermore, the water supply hose is formed by clamping and fixing multiple sections of water hose with carbon fiber load-bearing rope, so that the water hose only bears pressure and does not bear longitudinal tension. Each section of water hose is provided with quick connectors at both ends, and the beginning and end of each section of water hose are connected by quick connectors. Each quick connector is rigidly fixed to the carbon fiber load-bearing rope to form a segmented load-bearing structure. The top of the water supply hose is equipped with a rotating anti-twist joint to allow the hose to rotate circumferentially and prevent tangling. The rotating anti-twist joint is connected to the fire extinguishing unit via a quick connector. The end of the water supply hose is equipped with a hook.
[0015] Furthermore, in order to ensure that the spray gun operation and drones are not affected by the fire, they must be kept 20 meters away from the fire. The square nozzle consists of 2 sections, the round nozzle consists of 2 sections, each section of the telescopic nozzle has a travel of 5 meters, and the spray gun is 4 meters long.
[0016] Furthermore, each telescopic nozzle section is provided with a boss at its bottom, which serves as the mounting part of the bracket. A bracket is provided under the boss. The square nozzle has 3 pairs of brackets, and the round nozzle has 1 pair of brackets. The bracket is provided with a bearing mounting shaft and a bearing is installed on it. The bearing is set on each inner telescopic nozzle section. The bearing contacts the pipe wall of the adjacent outer telescopic nozzle and slides along its axial direction.
[0017] Furthermore, the telescopic nozzle assembly is equipped with a carbon fiber pull rope, one end of which is connected to the tail of the telescopic nozzle assembly, and the other end is connected to the innermost circular nozzle to prevent the spray gun from coming off.
[0018] Furthermore, the fire extinguishing pod has a turntable at the top and bottom of its front end, corresponding to the front ends of different levels of nozzles. The steel wire ropes are positioned between the lower turntable and the front end of the square nozzle, and between the upper turntable and the front end of the round nozzle. This improves the stability of the telescopic nozzle when fully extended.
[0019] A fire extinguishing method for an airborne fire extinguishing pod system for ultra-high-rise buildings includes the following steps: 1. Upon receiving a fire report, the first heavy-duty drone will install an airborne high-rise building fire extinguishing pod system containing a water-based fire extinguishing agent unit under the heavy-duty drone. The heavy-duty drone will fly to the fire scene and be remotely controlled by a handheld remote controller to spray fire extinguishing agents. It can control or suppress the fire without ground support, thus solving the problem of ground support or rescue personnel not being able to arrive in time. Firefighting procedures: S1) Activate the deployment mechanism to extend the telescopic nozzle assembly downwards and forwards in parallel; then activate the angle adjuster to make the telescopic nozzle assembly tilt downwards with the horizontal plane. When the telescopic nozzle assembly reaches a tilt angle of 30°, multiple nozzle sections will extend in sequence due to gravity; the turntable will tighten the fully extended telescopic nozzle assembly through a steel wire rope. S2) Adjust the flight altitude and distance to the fire using a handheld remote control, and spray the water-based fire extinguishing agent into the fire area at a predetermined angle through a spray gun to carry out fire suppression operations. Second, the second heavy-duty drone can simultaneously install an airborne fire extinguishing pod system for high-rise buildings containing foam extinguishing agents under the drone. After the drone flies to the fire scene, it can carry out continuous and thorough fire extinguishing operations with the cooperation of underground personnel, which is suitable for long-term operations. Firefighting procedures: S1) Activate the deployment mechanism to extend the telescopic nozzle assembly downwards and forwards in parallel; then activate the angle adjuster to make the telescopic nozzle assembly tilt downwards with the horizontal plane. When the telescopic nozzle assembly reaches a tilt angle of 30°, multiple nozzle sections will extend in sequence due to gravity; the turntable will tighten the fully extended telescopic nozzle assembly through a steel wire rope. S2) Release the water supply hose so that it extends vertically from below the rear of the fire extinguishing pod; S3) Start the high-lift submersible pump at the end of the water supply hose located at the surface water source to continuously supply water to the buffer tank through the water supply hose; fix the hook at the end of the water supply hose next to the surface water source; S4) Inside the fire extinguishing pod, start the foam liquid pump to inject the foam liquid in the foam liquid tank into the water circuit according to the preset ratio to form a mixture; S5) Start the air compressor and introduce compressed air into the mixer to mix water, foam liquid and air in the mixer to form compressed air foam; S6) Adjust the flight altitude and distance to the fire using a handheld remote control, and spray the compressed air foam at a predetermined angle into the fire area to complete the fire extinguishing operation; S7) After the fire is extinguished, first stop the ground water supply, drain the remaining water in the pipeline, release the hook, control the water hose reel to retrieve the water supply hose, then start the spray hose reel to reverse the carbon fiber load-bearing rope to retrieve the telescopic spray nozzle assembly, and then start the angle adjuster and the deployment mechanism in sequence, and the drone returns to base.
[0020] Beneficial effects of this invention: 1. This invention introduces water supply capacity from the ground to the high-altitude operation area through the vertical water delivery method of drones, realizing long-distance and continuous water supply for fires in super high-rise buildings, breaking through the limitations of traditional high-altitude platforms and conventional drone firefighting operations in terms of height and water supply capacity.
[0021] 2. A two-stage dynamic balancing mechanism is adopted. The first stage is a submersible pump deployed by a drone to the water source to deliver water vertically and overcome gravity. The second stage is a pump in the fire extinguishing pod to spray horizontally / divingly to provide range. This greatly reduces the internal pressure of the water supply hose and completely solves the industry pain points of water hose bursting and limited water supply height in high-rise fire fighting.
[0022] 3. The fire extinguishing pod integrates an air compressor and an air tank, and uses pneumatic pressurization to mix foam liquid and high-pressure air in real time in the nozzle, greatly increasing the operation time.
[0023] 4. By setting up a segmented load-bearing hanging water conveyance structure and using carbon fiber load-bearing rope clamps for fixation, the water conveyance pipeline can achieve a working state of only bearing pressure and not tension under ultra-long distance conditions, which significantly improves the structural reliability and operational stability of the hanging water conveyance system in high-altitude operations.
[0024] 5. The modular design allows for the alternating operation of multiple fire extinguishing units, providing both timely fire control and continuous firefighting protection.
[0025] 6. This invention adopts a guide-type telescopic spray gun structure, which avoids the dynamic seals from bearing pressure for a long time under high pressure conditions, thereby reducing the risk of leakage, jamming and wear, and improving the reliability and service life of the spraying device in continuous fire extinguishing operations.
[0026] 7. The design of the telescopic spray gun and the wire rope reel ensures that the spraying device maintains good straightness and anti-sway performance during telescopic extension and operation, thereby improving spraying stability and the pointing accuracy of the fire point.
[0027] 8. The fire extinguishing pod and the telescopic nozzle assembly together form a parallelogram mechanism. The unfolded parallelogram can reduce the recoil of the fire extinguishing agent and play a buffering role. Attached Figure Description

[0033] 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 some embodiments of the present invention, and not all embodiments. 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.
[0034] Example 1, as Figure 1-2As shown, the present invention discloses an airborne fire extinguishing pod system for ultra-high-rise buildings, comprising a heavy-duty drone 1 and a fire extinguishing pod 2. The fire extinguishing pod 2 can be quickly installed and disassembled on the support frame at the bottom of the heavy-duty drone 1. The quick installation can be achieved by using a hanger, quick-release buckle, bolt seat or plug-in locking mechanism. The heavy-duty drone 1 is a tandem dual-rotor drone with a maximum takeoff weight of 760 kg, a maximum payload of 300 kg, and an endurance of 2-4 hours.
[0035] The fire extinguishing pod 2 is equipped with a telescopic nozzle assembly below it, and the fire extinguishing pod 2 and the telescopic nozzle assembly 5 are connected by an unfolding mechanism 3; The deployment mechanism 3 can extend the telescopic nozzle assembly 5 downwards and forwards in parallel to reduce recoil. An angle adjuster 4 is provided between the fire extinguishing pod 2 and the telescopic nozzle assembly 5. The angle adjuster 4 is used to adjust the angle of the horizontal attitude of the telescopic nozzle assembly 5. This can increase the safe distance between the drone and the fire site. When the nozzle is extended, the fire extinguishing range can be extended by adjusting the angle, while keeping the drone's attitude stable.
[0036] The fire extinguishing pod 2 is equipped with a fire extinguishing unit 21, which is a water-based fire extinguishing agent fire extinguishing unit or a compressed air foam fire extinguishing agent fire extinguishing unit 21. Each fire extinguishing unit 21 is equipped with a spray pipe 210. like Figure 5 , 6 As shown, the telescopic nozzle assembly 5 is equipped with a telescopic nozzle 51. The telescopic nozzle 51 is a multi-section telescopic fitting structure with different thicknesses. The outer layer of the telescopic nozzle 51 is a square nozzle 52, and the inner layer of the telescopic nozzle 51 is a round nozzle 53. The front end of the round nozzle 53 is connected to a spray gun 6. The front end of the spray gun 6 is equipped with a quick-release nozzle 61, which can replace different nozzles to adapt to different scenarios. The square nozzle 52 has good support, and the round nozzle 53 has good flexibility. The fully extended telescopic nozzle 51 is up to 20 meters long. When the fire is large, the temperature next to the building is too high. Only when there is sufficient distance can drones and firefighting operations be safe.
[0037] In this embodiment, the square nozzle 52 is preferably composed of two sections, the round nozzle 53 is preferably composed of two sections, each section of the telescopic nozzle 51 has a stroke of 5 meters, the spray gun 6 is 4 meters long, and the fully extended telescopic nozzle 51 plus the external spray gun 6 has a length of 24 meters.
[0038] Each telescopic nozzle 51 has a boss 55 at its bottom, which serves as the mounting part of the bracket. A bracket 551 is provided under the boss 55. The square nozzle 52 has 3 pairs of brackets 551, and the round nozzle 53 has 1 pair of brackets 551. The bracket 551 is provided with a bearing mounting shaft 552 and a bearing 553 is installed on it. The bearing is set on each inner telescopic nozzle section. The bearing 553 contacts the pipe wall of the adjacent outer telescopic nozzle 51 and slides along its axial direction.
[0039] The telescopic nozzle assembly 5 is equipped with a carbon fiber pull rope 54. One end of the carbon fiber pull rope 54 is connected to the tail of the telescopic nozzle assembly 5, and the other end is connected to the innermost circular nozzle 53 to prevent the spray gun 6 from coming out.
[0040] Preferably, the fire extinguishing pod 2 has a turntable 22 at the top and bottom of its front end, with four turntables 22 corresponding to the front ends of different levels of nozzles. The steel wire rope 23 is correspondingly located between the lower turntable 22 and the front end of the square nozzle 52 and between the upper turntable 22 and the front end of the round nozzle 53, thereby improving the stability of the telescopic nozzle 51 when it is fully extended.
[0041] like Figure 9 As shown, a turntable 22 is provided in front of the fire extinguishing pod 2. The turntable 22 is wound with a steel wire rope 23. The front ends of the steel wire rope 23 are symmetrically arranged on both sides of the telescopic nozzle 51 and fixed to the front end of the nozzle. The steel wire rope 23 has a pulling effect, which can keep the spray gun 6 stable in the up, down and left and right directions during fire extinguishing operations. The spray pipe 210 is connected to the rear end of the spray gun 6 of the telescopic spray pipe 51. The fire extinguishing pod 2 is equipped with support legs 7 on its four sides for easy storage. The fire extinguishing pod 2 is also equipped with a control system 8 for controlling the fire extinguishing unit 21, the deployment mechanism 3, and the angle adjuster 4; The fire extinguishing pod 2 also includes a data and image transmission control system and a handheld remote control adapted to the control system 8.
[0042] The deployment mechanism 3 includes a connecting rod 31 and a lifting motor 32. The lifting motor 32 is located below the front end of the fire extinguishing pod 2. One end of the connecting rod 31 is connected to the output shaft of the lifting motor 32, and the other end is movably connected to the telescopic nozzle assembly 5. The angle adjuster 4 includes a lead screw 41, a lead screw nut 42, and a drive motor 43. The drive motor 43 is located in the lower middle part of the fire extinguishing cabin 2. The telescopic nozzle assembly 5 is provided with a lead screw nut 42 at its end. One end of the lead screw 41 is connected to the drive motor 43, and the other end is movably connected to the lead screw nut 42. The deployment mechanism 3 and the angle adjuster 4 are respectively used as adjacent linkage mechanisms, which together with the fire extinguishing pod 2 and the telescopic nozzle assembly 5 form a parallelogram mechanism. This mechanism enables the telescopic nozzle assembly 5 to maintain a predetermined attitude relationship during deployment, and can cooperate with the angle adjuster 4 to change the spray angle. Furthermore, the deployed parallelogram can reduce recoil and play a buffering role.
[0043] Example 2, as Figure 3 As shown, preferably, in scenarios where ground-based liquid supply support is not required and rapid response is needed, the fire extinguishing unit 21 is a water-based fire extinguishing agent unit, including a fire pump 221, a water-based fire extinguishing agent storage tank 222, and a spray hose reel 223. The spray hose 210 is connected to the fire pump 221; the fire pump 221 delivers water-based fire extinguishing agent from the water-based fire extinguishing agent storage tank 222 to the spray hose 210.
[0044] In this embodiment, a handheld remote control, via the control system 8, controls the fire pump 221 to extract the water-based extinguishing agent from the water-based extinguishing agent storage tank 222. This agent is then transported through the spray pipe 210 to the telescopic spray nozzle assembly 5, and finally sprayed from the nozzle 61 at the front end of the spray gun 6 to extinguish the fire. To facilitate aerial firefighting operations, the water-based extinguishing agent unit can be installed inside the firefighting pod 2, and the fire pump 221 can be started and stopped via the control system 8. The operating time varies from 5 to 30 minutes depending on the size of the water-based extinguishing agent storage tank 222.
[0045] Example 3, as Figure 4 , 10 As shown, preferably, for fire scenarios requiring ground-based liquid supply support, the fire extinguishing unit 21 is a foam liquid extinguishing agent unit, including a water supply unit, an air supply unit, a foam liquid tank 225, a foam liquid pump 226, a spray hose reel 223, and a mixer 227. The water supply unit includes a fire pump 221, a buffer water tank 224, and a hanging water delivery assembly. The hanging water delivery assembly includes a hose reel 228 and a water supply hose 229. The end of the water supply hose 229 is connected to a high-lift submersible pump 230 to prevent the water hose from bursting due to the high-pressure pump. The front end of the water supply hose 229 is connected to the buffer water tank 224. The buffer water tank 224 is equipped with a porous anti-sway baffle to reduce the impact of swaying on the center of gravity. The air supply unit includes a solenoid valve, a pressure regulating valve, an air storage tank 233, and an air compressor 234. Since the solenoid valve and pressure regulating valve are standard components commonly used in the field, their specific structures and working principles are well known to those skilled in the art. Furthermore, the inventive point of this application does not lie in improving these components; therefore, their structures are not described in detail in the specification, nor are they shown in the accompanying drawings. The mixer 227 is connected to the foam liquid tank 225, the water supply unit, and the air supply unit. The control system 8 controls the mixer 227 to mix the foam liquid, water, and air in a proportional manner and deliver them to the telescopic nozzle assembly 5 through the spray pipe 210.
[0046] like Figure 11 As shown, furthermore, the water supply hose 229 is formed by clamping and fixing multiple sections of water hose with carbon fiber load-bearing rope 241, so that the water hose only bears pressure and does not bear longitudinal tension. Each section of water hose is provided with quick connectors 244 at both ends, and the beginning and end of each section of water hose are connected by quick connectors 244. Each quick connector 244 is rigidly fixed to the carbon fiber load-bearing rope 241 to form a segmented load-bearing structure. The ends of the water supply hose 229 and the carbon fiber load-bearing rope 241 are rigidly fixed to the high-lift submersible pump, and the weight of the high-lift submersible pump tensions the carbon fiber load-bearing rope, avoiding the water hose from tangling. The water supply hose 229 consists of two 50-meter-long mesh high-pressure lightweight hoses and five 30-meter-long high-pressure water hoses, with a total length of 250 meters. The mesh high-pressure lightweight hoses are connected to the mandrel of the water hose reel 228, so that the water supply hose 229 can still effectively supply water even when it is not fully unrolled and there are still 100 reels on the reel. The top of the water supply hose 229 is provided with a rotating anti-twist joint 243 to allow the hose to rotate circumferentially and prevent tangling. The rotating anti-twist joint 243 is connected to the fire extinguishing unit 21 through a quick connector 244. The end of the water supply hose 229 is provided with a hook 9. In use, the foam extinguishing agent unit is first installed inside the fire extinguishing gondola 2, and the spray pipe 210 is connected to the telescopic spray pipe assembly 5. After the operation begins, the water supply hose 229 extends vertically from below the rear of the fire extinguishing gondola 2. A high-lift submersible pump 230 is located at the end of the water supply hose 229 and connected to a ground water source. After the submersible pump starts, water is continuously supplied to the buffer water tank 224 via the water supply hose 229. The water supply hose 229 can be composed of a carbon fiber load-bearing rope 241 and multiple sections of hose, with a rotating anti-twist joint 243 at the top.
[0047] After the water supply stabilizes, the foam liquid pump 226 is started to inject the foam liquid in the foam liquid tank 225 into the water supply circuit according to a preset ratio to form a mixture. At the same time, the air compressor 234 is started to deliver compressed air to the mixer 227 through the air storage tank 233, the pressure regulating valve and the solenoid valve. The mixer 227 mixes water, foam liquid and air to form compressed air foam. The resulting foam extinguishing medium is then delivered to the telescopic nozzle assembly 5 through the spray pipe 210, and finally sprayed into the fire area by the nozzle 61 at the front end of the spray gun 6 to extinguish the fire.

[0051] Example 4: Example of coordinated operation of initial suppression and continuous fire suppression. like Figure 7 , 8 As shown in the figure, this embodiment illustrates the specific way in which water-based fire extinguishing agent units and foam liquid fire extinguishing agent units are used together in the same fire fighting mission, so as to illustrate the adaptability of the platform-type fire extinguishing pod 2 system of the present invention in different fire fighting stages.
[0052] The airborne high-rise building fire extinguishing pod 2 system adopts a platform structure. The fire extinguishing pod 2 can be quickly installed and disassembled under the heavy-duty drone 1. The fire extinguishing pod 2 is equipped with a telescopic nozzle assembly 5. The fire extinguishing pod 2 and the telescopic nozzle assembly 5 are connected by an deployment mechanism 3 and an angle adjuster 4. The deployment mechanism 3 and the angle adjuster 4 can cooperate to realize the deployment and angle adjustment of the telescopic nozzle assembly 5. The fire extinguishing pod 2 is also equipped with a control system 8, which can be controlled by a handheld remote control.
[0053] In this embodiment, the fire extinguishing pod 2 is equipped with two types of fire extinguishing units 21 for coordinated fire extinguishing: the first type is a water-based fire extinguishing agent unit, and the second type is a foam liquid fire extinguishing agent unit. The water-based fire extinguishing agent unit includes a fire pump 221, a water-based fire extinguishing agent storage tank 222, and a spray hose reel 223. The fire pump 221 delivers the water-based fire extinguishing agent from the water-based fire extinguishing agent storage tank 222 to the spray hose 210. The foam liquid fire extinguishing agent unit includes a water supply unit, an air supply unit, a foam liquid tank 225, a foam liquid pump 226, a spray hose reel 223, and a mixer 227. The water supply unit includes a fire pump 221, a buffer water tank 224, and a hanging water delivery assembly. The air supply unit includes a solenoid valve, a pressure stabilizing valve, an air storage tank 233, and an air compressor 234.
[0054] I. Preparation for Receiving an Alarm Upon receiving the fire report, firefighters quickly retrieved the fire extinguishing gondola from its routine maintenance warehouse and rapidly installed the gondola, containing the water-based extinguishing agent unit, onto the first heavy-duty drone. After securing the connection between the gondola and the drone, they connected the fire hose to the telescopic nozzle's front connector. Once confirmed, the first heavy-duty drone took off from its base and headed to the fire alarm location. Simultaneously, firefighters quickly installed a foam extinguishing gondola onto the second heavy-duty drone. After securing the connection, they connected the fire hose to the telescopic nozzle's front connector. Once confirmed, the second heavy-duty drone also took off from its base and headed to the fire alarm location. Meanwhile, firefighters also loaded a spare foam extinguishing gondola onto a dedicated transport vehicle and rushed it to the fire scene. During firefighting operations, the airborne high-rise building fire suppression pod 2 system, equipped with the aforementioned water-based fire extinguishing agent unit, is used to perform initial suppression operations. After the heavy-duty UAV 1 arrives at the fire scene, the deployment mechanism 3 is activated, causing the telescopic nozzle assembly 5 to extend downwards and forwards. Then, the angle adjuster 4 is activated to make the telescopic nozzle assembly 5 form a downward spray angle. After the telescopic nozzle assembly 5 is deployed in place, it is tightened by the steel wire rope 23. Subsequently, the fire pump 221 is activated to deliver the water-based fire extinguishing agent to the telescopic nozzle assembly 5 through the spray pipe 210, and spray it onto the fire area from the nozzle 61 at the front end of the spray gun 6 to achieve rapid suppression of the fire. Simultaneously, the airborne high-rise building fire extinguishing pod 2 system, equipped with the aforementioned foam liquid fire extinguishing agent unit, is activated to perform continuous fire extinguishing operations. During operation, the telescopic nozzle assembly 5 is first deployed to the working state by the deployment mechanism 3 and the angle adjuster 4. Then, the hanging water supply assembly is released, allowing the water supply hose 229 to be vertically deployed from below the tail of the fire extinguishing pod 2. The high-lift submersible pump 230 located at the end of the water supply hose 229 is then activated, and the hook 9 at the end of the water supply hose 229 is fixed to the ground water source. Water is continuously supplied to the buffer water tank 224 through the water supply hose 229. Subsequently, the foam liquid pump 226 is activated to inject the foam liquid in the foam liquid tank 225 into the water circuit according to the preset ratio to form a mixture. At the same time, the air compressor 234 is activated to deliver compressed air to the mixer 227 through the air supply unit. The mixer 227 mixes the water, foam liquid, and air to form a foam extinguishing medium, which is then delivered to the telescopic nozzle assembly 5 through the spray pipe 210. The nozzle 61 at the front end of the spray gun 6 is continuously sprayed into the fire area to complete continuous fire extinguishing.
[0055] After the fire extinguishing operation is completed, the medium supply of the relevant fire extinguishing unit 21 is stopped; for the foam liquid fire extinguishing agent fire extinguishing unit, the ground water supply is stopped first, the remaining water in the pipeline is drained, the end hook 9 of the water supply hose 229 is released and the water supply hose 229 is retrieved, and then the telescopic nozzle assembly 5 is retrieved in sequence to restore the fire extinguishing pod 2 to the non-working state.
[0056] In this embodiment, the two types of fire extinguishing units 21 can adopt two cooperative methods: Firstly, a heavy-duty UAV 1 using a water-based fire extinguishing unit is used for independent fire extinguishing with water-based fire extinguishing agents. Secondly, two heavy-duty drones 1 are used to carry fire extinguishing pods 2 corresponding to different fire extinguishing units 21, and to carry out coordinated fire extinguishing simultaneously or sequentially.
[0057] Third, a batch of pods with independent fire-fighting capabilities can be stored in advance on high-rise buildings. When fighting a fire, drones can be unloaded and quickly go to the pod storage point near the fire to load ammunition and extinguish the fire.
[0058] IV. Joint firefighting operations for major fires When the fire situation at the scene is severe, coordinated firefighting operations should be carried out promptly. The specific firefighting operation steps are as follows: S1) After the first heavy-load drone flies to the fire scene and completes the rapid fire extinguishing operation, but the fire cannot be suppressed and effectively extinguished in time, the operation should be immediately switched to joint fire extinguishing. The heavy-load drone 1 should be quickly lowered to a safe position on the ground at the fire scene, and the fire extinguishing pod 2 that has completed the fire extinguishing operation should be quickly unloaded by the ground firefighters at the fire scene.
[0059] S2) After the fire truck carrying the backup fire extinguishing pod 2 arrives at the fire scene, the first heavy-duty drone uses the roof platform of the vehicle carrying the fire extinguishing pod 2 to quickly attach the fire extinguishing pod 2 and take off again.
[0060] S3) After the first heavy-load drone takes off again, it will continue to extinguish the fire in accordance with the fire extinguishing operation steps of the second heavy-load drone.
[0061] S4) If the first and second heavy-load drones are continuously fighting the fire, and the onboard 3% foam liquid runs out, they can land on the ground in time to quickly replace the fire extinguishing pod 2 or replenish the 3% foam liquid on site, and then continue to take off to fight the fire.
[0062] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the technical solution of the present invention is not limited to the above embodiments, nor is it limited to use only in rescue operations. Within the knowledge of those skilled in the art, various changes can be made without departing from the technical solution of the present invention. These changes involve related technologies well known to those skilled in the art, and all of these fall within the protection scope of the present invention.
