Description

Technical Field

[0001] This utility model belongs to the field of fire rescue technology, and specifically relates to a fire rescue drone and ground support device for ultra-high-rise buildings. Background Technology

[0002] Buildings with more than 10 stories or 24 meters in height are called high-rise buildings, and buildings with more than 100 meters in height are called super high-rise buildings. Fighting fires in high-rise and super high-rise buildings has always been a challenge in the fire protection field. Existing firefighting equipment, both domestically and internationally, is limited in its firefighting height, difficult to deploy quickly, and expensive, making it difficult to meet the needs of firefighting in high-rise and super high-rise buildings. Similarly, once a fire breaks out at a hazardous chemical storage site, conventional firefighting equipment cannot quickly approach the fire area, which severely restricts the effectiveness of rescue efforts. Utilizing drones to quickly enter dangerous areas for reconnaissance, detection, firefighting, and rescue can greatly reduce losses, improve rescue efficiency, and buy valuable time.

[0003] Firefighting in high-rise and super high-rise buildings typically employs aerial ladder trucks and ladder trucks. The world's tallest fire truck is the Finnish Braunto, which includes a chassis, lifting device, and electrical system. This fire truck has a lifting height of 101 meters and can relay water to low, medium, and high zones, with a water delivery height of approximately 160 meters. In its deployed state, the fire truck is approximately 8 meters wide, 20 meters long, has a travel height of 4 meters, and a total mass of 62 tons, making it unsuitable for deployment in densely populated areas and narrow streets.

[0004] Existing fire and rescue equipment has many limitations when facing high-rise building fires and complex fire environments, such as limited functionality, low fire extinguishing efficiency, and inability to conduct timely rescues of multiple people. Utility Model Content

It utilizes a small drone formation with ducted fans and pre-embedded steel wire strands in high-pressure water hoses to achieve stable water and power supply at heights of 300 meters and above, with minimal flow loss. Furthermore, the triple-sealing design of the hose connector (conical compression sleeve + positioning sleeve + threaded locking) reduces leakage under ultra-high water pressure.

[0032] 4. This utility model achieves energy and safety redundancy, namely, by integrating a waterproof power cord through a clamp ring to provide continuous power for the drone; the folding compartment of the fire truck can accommodate multiple small drones for landing and the arrangement of high-pressure water hoses, thus achieving the purpose of rapid rescue setup.

Detailed Implementation

[0047] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0048] Example 1

[0049] like Figures 1-7 As shown, this utility model embodiment specifically provides a fire rescue drone for ultra-high-rise buildings, including:

[0050] The multi-rotor airframe 1 includes a cabin 11 and a water storage tank 12. The multi-rotor airframe 1 is equipped with a cabin 11 and a water storage tank 12. The water storage tank 12 can provide a rescue water source for the water spray mechanism 5.

[0051] The retractable multi-level cloud bridge 2 and folding ladder 3 are installed inside the cabin 11. The multi-level cloud bridge 2 is installed on the last level of the cloud bridge. By controlling the extension of the multi-level cloud bridge 2, the folding ladder 3 can be connected to the windowsill of the high-rise building, so that the residents of the high-rise building can quickly enter the multi-level cloud bridge 2 through the folding ladder 3. Then the multi-level cloud bridge 2 can be retracted into the multi-rotor body 1 to complete the rapid rescue of the residents.

[0052] Window breaker 4 is symmetrically arranged above the inner wall of the last level of the cloud bridge. By controlling the action of window breaker 4, the glass of the high-rise window sill can be broken; so as to facilitate the quick passage of residents or the extension and placement of folding stairs 3.

[0053] The water spraying mechanism 5 is installed on the front and rear sides of the multi-level cloud bridge 2 and on the top of the cabin 11. Water is supplied through the water storage tank 12. By controlling the action of the water spraying mechanism 5, water can be sprayed to extinguish fires in the high-rise interior, thereby improving the fire extinguishing efficiency.

[0054] The multi-rotor fuselage 1 also includes an automatic hatch 13, which, when opened, provides access for the multi-level cloud bridge 2 and the folding stairs 3.

[0055] It also includes a tilting rotor 14, which is located at one end of the multi-rotor body 1 away from the folding steps 3. By switching the tilting rotor 14 to tilt upward or downward by 90°, it can assist the multi-rotor body 1 in moving closer to or away from the high-rise windowsill.

[0056] The window breaker 4 includes an electric push rod and a conical window breaker head; the drive end of the electric push rod is equipped with a conical window breaker head, and the conical window breaker head is driven to apply an impact force to break the tempered glass by controlling the extension of the electric push rod.

[0057] The multi-level cloud bridge 2 includes: a first-level cloud bridge 21, a second-level cloud bridge 22, and a third-level cloud bridge 23; each level of the cloud bridge includes: a drive bridge plate 24 and a U-shaped bridge plate 25; the two ends of the U-shaped bridge plate 25 are integrally formed and connected to the drive bridge plate 24; the first-level cloud bridge 21, the second-level cloud bridge 22, and the third-level cloud bridge 23 are arranged radially from the outside to the inside; the drive bridge plate 24 on the first-level cloud bridge 21 is connected to the cabin 11 via a first-level electric telescopic rod; the drive bridge plates 24 on the first-level cloud bridge 21 and the second-level cloud bridge 22 are connected via a second-level electric telescopic rod; the drive bridge plates 24 on the second-level cloud bridge 22 and the third-level cloud bridge 23 are connected via a third-level electric telescopic rod; the first-level cloud bridge 21, the second-level cloud bridge 22, and the third-level cloud bridge 23 also include several ball bearing slides to ensure the smoothness and stability of the first-level cloud bridge 21, the second-level cloud bridge 22, and the third-level cloud bridge 23 when extending or retracting.

[0058] Furthermore, each of the above-mentioned cloud bridges has a limiting block 26 on the end side wall near the folding staircase 3, which serves to block and protect the multi-level cloud bridge 2 when it is folded up at each level.

[0059] As a further explanation of the embodiments of this utility model, the aforementioned third-level cloud bridge 23 also includes multiple safety seats, so that successfully rescued personnel can sit down and fasten their safety belts. At the same time, safety rope nets are included at the top open end and the front and rear open ends of the third-level cloud bridge 23 to further enhance the safety performance of personnel when entering. The height of the safety rope net near the end of the folding step 3 can be adjusted and locked so as not to affect the height of the rescue personnel entering and exiting. Even after the rescue personnel can pass through smoothly, they can be lowered and fixed.

[0060] As a further explanation of the present utility model, the interior of the water storage tank 12 may be provided with a multi-layer mesh plate structure to further connect the water through the holes in the mesh plate, so as to form a wave-damping plate to avoid the fluctuations generated on the water surface during the flight of the UAV affecting its flight attitude or flight stability.

[0061] It should also be noted that the bottom of the water storage tank 12 includes a downward-protruding recessed water trough, which is used to connect with the end of the water pipe inside the water storage tank 12 to ensure water supply.

[0062] The folding staircase 3 includes: a first-level staircase 31, a second-level staircase 32, a shock absorber 33, and a handrail 34; one end of the first-level staircase 31 is rotatably mounted to the end of the last step of the cloud bridge via a motor-driven power shaft, and the other end of the first-level staircase 31 is rotatably mounted to one end of the second-level staircase 32 via a motor-driven power shaft; a handrail 34 is provided on the first-level staircase 31, and a shock absorber 33 is provided at the bottom of the first-level staircase 31. The shock absorber 33 includes: a fixed rod 331, a buffer box 332, a fixed box 333, and a buffer spring 334; the fixed rod 331 is located at the bottom of the first-level staircase 31, the buffer box 332 is slidably mounted on one side of the fixed rod 331, and the fixed box 333 is fixedly mounted on the other side of the fixed rod 331. The buffer box 332 is slidably sleeved on the fixed box 333, and several buffer springs 334 are arranged between the buffer box 332 and the fixed box 333. During rescue operations, the first-level ladder 31 is rotated from a vertical to a horizontal position by a motor. Subsequently, the second-level ladder 32 is rotated 180 degrees from a horizontal position to a vertical position by a motor, allowing it to hook onto the interior of the high-rise window sill, thus ensuring the stable construction of the folding ladder 3 and the multi-level cloud bridge 2. Furthermore, the aforementioned shock absorber 33, with its buffer spring 334, provides elastic cushioning against the high-rise building wall during the deployment of the first-level ladder 31, thus protecting the folding ladder 3 from hard impacts and the risk of a crash.

[0063] The water spraying mechanism 5 includes: a water spray gun 51, a booster pump, and a water pipe; one end of the water spray gun 51 is connected to the water storage tank 12 through the booster pump and the water pipe; the water spray gun 51 is located on the top of the engine room 11 and can be driven by a motor to rotate horizontally to increase the spraying area; the water spray gun 51 located on both sides of the multi-stage cloud bridge 2 also includes: a rotary motor 52 and an arc-shaped groove support plate 53; the rotary motor 52 and the arc-shaped groove support plate 53 are respectively installed at the end of the last stage cloud bridge, and the output end of the rotary motor 52 is equipped with a water spray gun 51. When spraying water, the angle of the water spray gun 51 is adjusted so that it abuts against the arc-shaped groove support plate 53 to overcome the back thrust generated by the water spray. When the water spray guns 51 located on both sides of the multi-level cloud bridge 2 are not in use, their nozzles face downwards. When extinguishing a fire, the water spray guns 51 are rotated by controlling the rotating motor 52 to deflect upwards until the nozzles face forward and upwards, i.e., at an upward tilt angle with the horizontal plane, so that the water spray guns 51 spray water forward and upwards to extinguish the fire. At this time, the deflected water spray guns 51 abut against the arc-shaped groove support plate 53 to eliminate the backward thrust generated when spraying water.

[0064] The water spray guns 51 located on both sides of the multi-level cloud bridge 2 also include a water pipe storage mechanism 6. The water pipe storage mechanism 6 includes: an electric disc 61, a steel wire rope 62, a fixing ring 63, and a fixing ring 64. Three electric discs 61 are arranged alternately on the front and rear side walls of the engine room 11. Each electric disc 61 has a steel wire rope 62 wound on it. Two fixing rings 63 are respectively located at the ends of the first-level cloud bridge 21 and the second-level cloud bridge 22. Three fixing rings 64 are respectively located on the water pipes laid at each level of the cloud bridge. At the midpoint of point 1, the other ends of the three steel wire ropes 62 are respectively connected to the three fixed rings 64. When the multi-level cloud bridge 2 is retracted, each electric disc 61 is controlled to retract in sequence. Each fixed ring 64 pulls a section of water pipe laid by each level of cloud bridge to the front and rear side walls of the cabin 11, so that each section of water pipe is retracted and placed on the circular tube platform 65 with ball bearing bushings, which is used to support and place the retracted water pipe. The circular tube platform 65 is set on the front and rear side walls of the cabin 11. Through the design of the water pipe storage mechanism 6, the electric disc 61 corresponding to each section of water pipe is rotated and wound up. The steel wire rope 62 will pull the middle point of each section of water pipe to move to one side of the UAV cabin 11. At this time, it will form a dragging effect on the section of water pipe, causing it to bend into two strands (similar to forming a U-shaped bend) and be dragged and stored in the cabin 11 at the side wall of the first-level cloud bridge 21. When the third-level cloud bridge completes the retraction in the cabin 11, the water pipes stored in the same way will not affect the retraction of the cloud bridge.

[0065] It also includes an auxiliary water supply source 7, which includes: a small door 71, an electric disc 72, a booster pump 73, a steel wire rope 74, a water pipe 75, and a lifting ring 76. A small door 71 is provided at the bottom of one end of the multi-rotor body 1. The small door 71 is opened and closed by a motor. The electric disc 72 and the booster pump 73 are installed inside the multi-rotor body 1 inside the small door 71. One end of the booster pump 73 is connected to one end of the water pipe 75. The booster pump 73 pumps the water source transported by the water pipe 75 to the water storage tank 12. The electric disc 72 has a steel wire rope 74 wound on it. The other end of the steel wire rope 74 is connected to the lifting ring 76. The lifting ring 76 is fixed at the middle point of the water pipe 75. When the drone needs to lower water hose 75, the small hatch 71 is opened, and water hose 75 extends downwards synchronously with the steel cable 74 released by the electric disc 72. At this time, water hose 75 can be docked with the high-pressure water hose 94 carried by the drone formation in the ground support device to replenish the drone's water or power supply in a timely manner (during docking, the drone flies at a low altitude to facilitate docking by ground rescue personnel). Moreover, thanks to the steel cable 74 and the lifting ring 76, water hose 75 can be retrieved by rotating the electric disc 72, which will lift and pull water hose 75 into the cabin.

[0066] As a further illustration of this embodiment, the cabin 11 of the fire rescue drone contains a power supply compartment to power the onboard equipment. When the fire rescue drone docks with a supporting small drone 9, it can use the power supplied by the small drone 9. Simultaneously, the fire rescue drone is equipped with a series of devices for navigation, flight control, and search, including lidar, millimeter-wave radar, high-definition cameras, far-infrared sensors, searchlights, and loudspeakers.

The fire truck 8's cargo compartment includes: a main body 81, side panels 82, and a roof 83. Several ground-level helipads are linearly distributed at the bottom of the main body 81. The side panels 82, L-shaped, are rotatably mounted on the top of the two side walls of the main body 81 via motor-driven shafts. The roof 83 is rotatably mounted on the top of the side panels 82 via motor-driven shafts. A first helipad 84 is linearly distributed inside the main body 81, and a second helipad 85 is linearly distributed on the bottom of the L-shaped side panels 82. The main body 81, side panels 82, and roof 83 are connected to each other. The joint gaps are sealed and waterproofed by a textured waterproof sealing layer. The opening of the carriage can be achieved by controlling the rotation of the motor at the top panel 83, which will cause the top panels 83 on both sides to deflect outward by 180 degrees until the top panels 83 are horizontal. At this time, the batch of small drones 9 that landed on the second helipad 85 can take off outward in sequence. After all the batch of small drones 9 on the second helipad 85 have taken off, the motor at the side panel 82 can be controlled to rotate, which will cause the side panels 82 on both sides to deflect outward by 90 degrees until the bottom of the side panel 82, i.e. the L-shaped panel, is vertical and the side panels are horizontal. At this time, the batch of small drones 9 that landed on the first helipad 84 can take off outward in sequence. Moreover, the first helipad 84 is a single-piece structure, while the second helipad 85 is a separate-piece structure. The first helipad 84 has landing positioning slots 88 at the four corners of the single-piece structure, while each separate piece of the second helipad 85 has two landing positioning slots 88. The two separate pieces are symmetrically arranged and set on the bottom plate of the L-shaped plate of the side panels 82 of the two carriages to form the structure of the second helipad 85. When the two separate pieces are combined, a cavity will be left in the middle, that is, a strip-shaped groove will be formed in the middle of the structure of the second helipad 85 to allow the high-pressure water hose 94 under the top-level small drone 9 to pass through.

[0071] Several small drones 9 land sequentially on the first landing pad 84 and the second landing pad 85. Each small drone 9 includes a booster pump 91, a rotor arm 92, and a ducted fan 93. The booster pump 91 is surrounded by rotor arms 92, and the other end of each rotor arm 92 is equipped with a ducted fan 93. The input and output ends of the booster pump 91 on each small drone 9 are integrally connected to a high-pressure water hose 94. The high-pressure water hoses 94 on each pair of adjacent small drones 9 are detachably locked together through a hose connector 10. Several small drones 9 are suspended sequentially at corresponding heights to form a vertical formation array to supply water and power to the fire rescue drones. Each small drone 9 is equipped with a battery pack and a positioning and navigation sensor system.

[0072] It should be noted that the booster water pump 91 on the aforementioned small drone 9 is directly connected to the high-pressure water hose 94 and the power cord 110, meaning that there is no need to reconnect when the aforementioned small drone 9 takes off, and it is also connected after landing, without the need to disassemble.

[0073] By releasing batches of small drones 9 in sequence, a vertically arranged array can be formed. Each small drone 9 carries a section of high-pressure water hose 94 to form a water supply pipeline, which can promptly replenish water or power to rescue drones hovering at high altitudes.

[0074] It also includes a hose concentrator 86, which is installed on the first landing pad 84 and the second landing pad 85. The hose concentrator 86 includes a concentrator plate 87 and a concentrator motor. The concentrator plate 87 is symmetrically distributed on both sides of the first landing pad 84 and the second landing pad 85. The bottom shaft end of the concentrator plate 87 is connected to the output end of the concentrator motor. The concentrator motor is installed on the corresponding first landing pad 84 and the second landing pad 85. The concentrator motor drives the concentrator plates 87 on both sides to rotate closer to each other, so as to place the high-pressure hose 94 of the small UAV 9 landing on the first landing pad 84 or the second landing pad 85 inward, so as to avoid obstructing the landing positioning slots 88 opened at the four corners of the first landing pad 84 and the second landing pad 85. When the aforementioned small drone 9 is landing on the helipad but still has some height before landing, the two side aligning plates 87 are in a horizontal state with their sides tilted outwards. The high-pressure water hoses 94 carried by the small drone 9 will be piled up haphazardly on the helipad or on the aligning plates 87. At this time, the aligning motor can be controlled to rotate, causing the two side aligning plates 87 to tilt inwards towards each other until they are in a vertical state. The high-pressure water hoses 94 piled up on the aligning plates 87 can then be moved inwards to prevent them from piling up near the landing positioning slot 88 and affecting the accurate positioning and landing of the small drone 9.

[0075] The first and second parking aprons 84 and 85 mentioned above also include symmetrically arranged support buffer rods 89. The support buffer rods 89 are spring rod structures, which are used to support the bottom plate of the L-shaped plate of the side panel 82 of the carriage and the top plate 83 of the carriage, respectively.

[0076] The hose connector 10 includes: a plug 101, a socket 102, a fastening ring 103, a handle 104, a hook 105, an internal threaded sleeve 106, an external threaded sleeve 107, and a hook ring 108. The plug 101 and socket 102 are integrally formed and connected to both ends of the high-pressure water hose 94, and are connected by a plug-in joint. The plug 101 also includes a rotatably mounted internal threaded sleeve 106, and the socket 102 includes an integrally formed external threaded sleeve 107, which is threadedly connected to the internal threaded sleeve 106. A fastening ring 103 is integrally formed and connected to the socket 102, as well as the input and output ends of the booster pump 91. A handle 104 is hinged around the fastening ring 103 on the connector 101. A hook rod 105 is hinged to the handle 104. The other end of the hook rod 105 is hooked onto the hook ring 108. The hook ring 108 is integrally formed and connected to the socket 102. A steel wire strand is pre-embedded in the inner circumference of the high-pressure water hose 94 or a steel wire strand is provided in the outer circumference. The two ends of the steel wire strand are respectively tightened and connected to the fastening ring 103 at the booster pump 91 and the fastening ring 103 at the hose connector 10 by locking bolts.

[0077] The connector 101 includes: an outer conical clamping sleeve 1011, a first positioning sleeve 1012, and a second positioning sleeve 1013; the outer conical clamping sleeve 1011 is provided with the first positioning sleeve 1012 and the second positioning sleeve 1013 in sequence with the center on the outer radial side.

[0078] The socket 102 includes: an inner conical clamping sleeve 1021 and a third positioning sleeve 1022; the third positioning sleeve 1022 is concentrically fitted on the outer radial side of the inner conical clamping sleeve 1021; the outer conical clamping sleeve 1011 is clamped and connected to the inner conical clamping sleeve 1021; the first positioning sleeve 1012 and the second positioning sleeve 1013 are respectively clamped onto the inner and outer walls of the third positioning sleeve 1022; both the plug 101 and the socket 102 have O-rings at the bottom of their inner cavities; When using the hose connector 10, the connector 101 can be quickly inserted into the socket 102. This applies force through the wedge-shaped surface of the inner conical clamping sleeve 1021, compressing the outer conical clamping sleeve 1011. This causes elastic deformation of the thin wall of the outer conical clamping sleeve 1011, thereby clamping the second positioning sleeve 1013. The first positioning sleeve 1012, the second positioning sleeve 1013, and the third positioning sleeve 1022 are also connected through insertion to further enhance the locking and sealing effect. Furthermore, the inner threaded sleeve 106 is then rotated to further lock it with the outer threaded sleeve 107, ensuring reliable locking between the connector 101 and the socket 102. At the same time, by turning the handle 104 upward, the hook rod 105 is hooked onto the hook ring 108. Then, by pressing the handle 104 downward, a downward force is applied to the hook rod 105. At this time, the connector 101 and the socket 102 can be locked together by this force, thereby ensuring the reliability of the high-pressure water hose 94 when supplying water and avoiding pressure loss, leakage or disconnection.

[0079] As a further explanation of this utility model, the hook rod 105 is a two-section hook structure with an inclined included angle or a two-section hinged hook rod structure, which facilitates locking. The high-pressure water hose 94 has steel wire strands pre-embedded in its inner circumference or located on its outer side. The two ends of the steel wire strands are respectively connected to the fastening ring 103 at the booster pump 91 and the fastening ring 103 at the hose connector 10 by locking bolts. This further enhances the overall structural stability between the high-pressure water hose 94 and the booster pump 91, ensuring the safety and reliability of high-pressure water supply.

[0080] It also includes clamp rings 109 and power lines 110. Each section of high-pressure water hose 94 also includes several linearly arranged clamp rings 109. Power lines 110 are tightly fastened on the clamp rings 109. Power is supplied to each adjacent pair of power lines 110 through a power socket. The bottom power line 110 is electrically connected to the emergency power supply, and the top power line 110 is electrically connected to the power supply port of the fire rescue drone.

[0081] As a further illustration of the embodiments of this utility model, the embodiments of this utility model also include the following operation process:

[0082] This fire rescue drone can be both remotely controlled and autonomously controlled. Once airborne, it can quickly reach the fire scene using BeiDou / GBS positioning, simultaneously activating its automatic fire (smoke) source search system to locate the fire point and guide the water cannons. Upon reaching the fire scene, the drone can quickly descend to a height close to the fire, facilitating firefighting and rescue efforts. The drone's cabin door automatically opens under the push of a motor / electric actuator. After the door opens, the window breaker inside the hovercraft extends from the cabin under the push of the electric actuator, striking and shattering the burning window glass. If there are trapped personnel inside, the main unit can extend the hovercraft, lowering and extending a ladder at the front of the hovercraft to enter the burning room. Trapped personnel can then enter the cabin via the hovercraft, fasten their seatbelts, and wait to return to the ground. With the support of sensors, the water cannons automatically locate key fire sources and spray water sequentially through the broken window into the fire point inside the room until the fire is extinguished. After the fire is extinguished, it can return to base remotely or autonomously.

[0083] If the fire-fighting drone runs out of onboard water but the fire still exists, the drone should quickly land on the ground, and any trapped personnel should evacuate. Once the drone reaches a certain altitude, ground support personnel should connect it to a fire truck to supply water and / or power, allowing the small drone platoon to continue its firefighting efforts. Fire-fighting drones can utilize the water and electricity provided by small drone platoons carrying hoses and / or power cables for extended firefighting and rescue operations. These small drone platoons, equipped with hoses and / or power cables, can be precisely vertically arrayed from top to bottom. Each water / electricity-equipped drone consists of a high-pressure hose, inlet and outlet connectors, a power cable, inlet and outlet power connectors, and a booster pump.

[0084] At this point, the ground fire trucks have their onboard hoses connected to ground fire hydrants, providing a continuous water supply for firefighting. The ground fire trucks also have powerful battery packs (which can also be connected to public power sources) to allow firefighting drones to remain airborne for extended periods for firefighting operations. Small drone teams carrying hoses / cables, consisting of several identical drones, each capable of carrying the same length (height) of hose / cable, supply water and electricity to the firefighting drones. The number of hose / cable drone teams can be automatically configured based on the height of the building in the fire. After the firefighting mission is completed, with the support of a sensor positioning system, the firefighting drones and the onboard small drones fly above the fire trucks and descend one by one onto the fire truck's landing pad. As the small drones land, the fire hoses naturally fall and accumulate beneath the small drones, inside the landing gear. The first floor is full. The second floor parking area is then restored to its original state. The small drone continued its descent, with the water hoses from the drones above and those from the already landed drones passing through the gap in the middle of the second-level helipad and landing on the second-level helipad. The small drones continued their descent, and the water hoses naturally fell and accumulated until they came to a stop. After the last small drone landed, the water hose below the fire rescue drone was on the ground. At this point, ground crew went to disconnect the water hoses from the small drones and placed that section of hose on the fire truck. Then, the fire rescue drone's motor turntable tightened the cable to retrieve the water hose, closed the small hatch, and flew back to its base. The water hose / cable recovery of the small drone was complete, and the ground fire truck departed for its return trip.

[0085] Furthermore, the following process can be further adapted as needed:

[0086] The gimbals equipped on fire rescue drones can transmit real-time images of the fire scene back to the control console and handheld remote control screen, allowing operators to control firefighting efforts and store data. They can also wirelessly connect to public security fire brigades to transmit real-time fire scene images and receive commands for unified control. With the support of sensor systems, fire rescue drones can also achieve fully automated, autonomous firefighting.

[0087] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
