Firefighting equipment and fire trucks

[0001] Cross-references to related applications

[0002] This application claims priority to Chinese Patent Application No. 202411620034.0, filed on November 13, 2024, entitled "Firefighting Overhead Equipment and Fire Truck", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of fire protection technology, and more specifically, to a fire-fighting superstructure and fire truck. Background Technology

[0004] With the development of the world economy, the number of high-rise and super high-rise buildings in cities is increasing. Once a fire breaks out in a high-rise building that is tens or even hundreds of meters tall, it will face fire protection challenges.

[0005] Currently, there are some firefighting drones based on multi-rotors on the market, but their payload capacity is small, and they can only carry a few fire extinguishing bombs. If the payload capacity of multi-rotor drones is to be increased, the corresponding size will increase, which will further lead to a larger size of the superstructure used to accommodate the multi-rotor drone, occupying more space and resulting in a low degree of integration of the entire superstructure. Summary of the Invention

[0006] This application provides a fire-fighting superstructure and a fire truck, which can reduce the size of the fire-fighting superstructure and improve the integration of the entire superstructure.

[0007] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0008] The embodiments of this application can be implemented as follows:

[0009] In a first aspect, this application provides a fire-fighting superstructure, comprising: a housing configured to store and protect other system modules; a liquid tank configured to store a fire extinguishing agent and a power generation module configured to provide power to a ducted drone; a tethered cable reel connected to the power generation module and configured to supply power to the ducted drone; a water pump system configured to output the fire extinguishing agent from the liquid tank; and a support platform located above the liquid tank; wherein the liquid tank, the water pump system, and the tethered cable reel are arranged along the same length direction of the housing and are all located below the housing, and the power generation module is located on one side of the tethered cable reel; the housing and the support platform form a receiving space configured to accommodate the ducted drone.

[0010] In the implementation of the above solution, the fire-fighting superstructure includes: a housing configured to store and protect other system modules; a liquid tank for storing extinguishing agent, which can be used for fire extinguishing; a power generation module configured to provide power to the ducted drone; a tethered cable reel connected to the power generation module and configured to supply power to the ducted drone; a water pump system configured to output the extinguishing agent from the liquid tank; and a support platform located above the liquid tank. The liquid tank, water pump system, and tethered cable reel are arranged along the same length of the housing and are all located below the housing. The power generation module is located on one side of the tethered cable reel. The housing and support platform form a space configured to accommodate the ducted drone, thus making the layout of the various components within the housing in this embodiment reasonable, highly integrated, and able to increase the flow rate of the extinguishing agent. Compared to the superstructure of a rotary-wing drone, it is smaller in size, easier to transport or place, reduces the space occupied in the width direction of the housing, and can pass through narrow spaces during transportation, improving the adaptability of the superstructure.

[0011] In one embodiment, the fire-fighting superstructure includes a ducted drone, which is longitudinally elongated and located above the liquid tank. The extension direction of the ducted drone is consistent with the arrangement direction of the liquid tank, the water pump system, and the mooring cable reel.

[0012] In the implementation of the above solution, the fire-fighting superstructure includes a ducted drone. The ducted drone is longitudinally elongated, meaning that its extension direction is along its own length, reducing the width space occupied by the ducted drone. This facilitates the fire-fighting superstructure passing through narrow areas. Compared to areas that ladders or rotary drones cannot pass through, this increases the application scenarios of the ducted drone and improves its adaptability. The ducted drone is located above the liquid tank, and its extension direction is consistent with the arrangement direction of the liquid tank, water pump system, and mooring cable reel. This allows the ducted drone to make full use of the space above the liquid tank, making the internal layout of the container more reasonable and reducing the space occupied in the width direction of the container, thus reducing space occupation and facilitating transportation and placement.

[0013] In one embodiment, the ducted unmanned aerial vehicle includes a support beam, with at least four ducted propulsion systems on each side of the support beam.

[0014] In the implementation of the above scheme, the ducted unmanned aerial vehicle (UAV) includes a support beam. At least four ducted propulsion systems are provided on one side of the support beam. The support beam provides a support structure for the ducted propulsion systems. The localized duct design also makes the ducted UAV a longitudinal structure, reducing the space occupied by the ducted UAV in width. Using multiple ducted UAVs can further improve the payload capacity of the ducted UAV. Furthermore, by using a larger number of ducted UAVs, when one of the ducted propulsion systems on one side of the support beam is damaged, the other ducted propulsion systems on the same side can compensate for the corresponding lift, which facilitates the control of the ducted UAV and also improves the risk resistance and stability of the ducted UAV.

[0015] In one embodiment, the fire-fighting superstructure is configured to be installed on a fire truck, with the power generation module located near the rear of the fire truck's cab; the liquid tank is located at the rear of the housing; the tethered cable reel is located behind the power generation module; and the water pump system is located between the tethered cable reel and the liquid tank.

[0016] In implementing the above scheme, the fire-fighting superstructure can be installed on a fire truck, allowing the fire truck to extinguish high-rise fires through confined spaces, thus improving its adaptability. The generator module can be located behind the fire truck cab, with the liquid tank at the rear of the vehicle body. Since the liquid tank contains extinguishing agent and is relatively heavy, and the generator module also has a certain weight, placing the generator module behind the cab and the liquid tank at the rear of the vehicle body balances the overall weight of the fire truck, ensuring stability while driving. This rational layout also improves space utilization on the fire truck. The mooring cable reel is located behind the generator module, shortening the distance between them and facilitating connection. The water pump system is located between the mooring cable reel and the liquid tank, a rational layout that also shortens the distance between the water pump system and the liquid tank, reducing pipe connections. This also makes the fire-fighting superstructure compact, improving space utilization and allowing it to pass through confined areas, thus improving fire-fighting efficiency.

[0017] In one embodiment, the fire-fighting superstructure also includes a lifting mechanism connected to the housing and the support platform, located above the liquid tank, and configured to lift the ducted drone above the housing.

[0018] In the implementation of the above scheme, the fire-fighting superstructure also includes a lifting mechanism. The lifting mechanism is connected to the box and the support platform and is located above the liquid tank to improve space utilization. The lifting mechanism can lift the ducted drone to a height above the box, avoiding the box from obstructing the ducted drone and facilitating its flight.

[0019] In one implementation, the support platform is provided with multiple through holes.

[0020] In the implementation of the above scheme, the support platform is equipped with multiple through holes, which allow the airflow generated by the ducted propulsion system to pass through the support platform, reducing the disturbance of the airflow to the ducted UAV and improving the stability of the ducted UAV during takeoff and landing.

[0021] In one embodiment, the tethered cable reel includes a support frame and a winch. The winch is used to wind the cable and is rotatable relative to the support frame. The support frame is also equipped with a drive motor and a take-up device. The cable is used to pass through the take-up device and connect to the ducted UAV. The support frame is also equipped with a guide rod and a threaded rod. Both the threaded rod and the guide rod are connected to the take-up device. The drive motor can drive the threaded rod to rotate.

[0022] In the implementation of the above scheme, the tethered cable reel includes a support frame and a winch. The winch is used to wind the cable and can rotate relative to the support frame. The support frame is also equipped with a drive motor and a take-up device. The cable can pass through the take-up device and connect to the ducted UAV. The support frame is also equipped with a guide rod and a threaded rod, both of which are connected to the take-up device. The drive motor can drive the threaded rod to rotate, causing the take-up device to move along the threaded rod. At the same time, the guide rod guides the take-up device, ensuring that the take-up opening of the take-up device is always facing upwards, facilitating cable take-up and release. The take-up device is slidably connected to the guide rod, facilitating the movement of the take-up device along the guide rod. Simultaneously, the winch can be driven to rotate while the cable is being taken up and released, improving the smoothness of cable take-up and release.

[0023] In one implementation, the cable and the water hose are wrapped together by a protective sleeve.

[0024] In the implementation of the above solution, the cable and hose are wrapped together with a protective sleeve, which prevents the cable and hose from getting tangled in the air and improves the safety of the fire-fighting equipment.

[0025] Secondly, this application provides a fire truck, including the fire-fighting superstructure provided in the first aspect; a power generation module located near the rear of the fire truck cab; a liquid tank located at the rear of the tank; a tethered cable reel located at the rear of the power generation module; and a water pump system located between the tethered cable reel and the liquid tank.

[0026] In the implementation of the above solution, the fire-fighting superstructure includes the fire-fighting superstructure provided in the first aspect. The power generation module is located at the rear of the fire truck cab, and the liquid tank is located at the rear of the body. Since the liquid tank stores extinguishing agent and is relatively heavy, and the power generation module also has a certain weight, placing the power generation module at the rear of the cab and the liquid tank at the rear of the body can balance the weight of the entire fire truck and ensure stability when driving the fire truck. At the same time, the layout is reasonable and improves the space utilization rate on the fire truck.

[0027] The mooring cable reel is located behind the generator module, shortening the distance between them and facilitating connection. The water pump system is located between the mooring cable reel and the liquid tank, a rational layout that also shortens the distance between the pump system and the liquid tank, reducing pipeline connections. This also makes the fire-fighting superstructure compact, improving space utilization and allowing it to pass through narrow areas, thus improving fire-fighting efficiency.

[0028] In one embodiment, the fire-fighting superstructure also includes a lifting mechanism connected to the fire truck and configured to place the ducted UAV from the fire truck to the ground, or to place the ducted UAV from the ground onto the fire truck.

[0029] In the implementation of the above scheme, the fire-fighting superstructure also includes a lifting mechanism. The lifting system is installed on the fire truck and can be used to place the ducted drone from the fire truck to the ground, or to place the ducted drone from the ground onto the fire truck, which can realize the efficient movement of the ducted drone and reduce the cost of manual handling.

Detailed Implementation

[0042] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0043] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] Firstly, this application provides a fire-fighting superstructure device that can be fixed to a mobile device or a fixed device, such as a support platform 6 in a residential area or a fire truck, thereby improving the adaptability of the fire-fighting superstructure device.

[0045] As shown in Figures 2 and 3, the fire-fighting superstructure includes: a housing 1, configured to store and protect other system modules; a liquid tank 2, which stores extinguishing agent for use in fire suppression; a power generation module 3, electrically connected to a ducted drone 7, providing power to the drone and enabling it to carry a hose for fire suppression; a mooring cable reel 4, electrically connected to both the power generation module 3 and the ducted drone 7, transmitting the electrical energy generated by the power generation module 3 to the drone 7; and a water pump system 5, configured to output the extinguishing agent from the liquid tank 2, which is then sprayed out through a fire monitor 73 to achieve [fire suppression]. The purpose of fire extinguishing; support platform 6, located above liquid tank 2; wherein, liquid tank 2, water pump system 5 and tethered cable reel 4 are arranged along the same length direction of box 1 and are all located below box 1, and power generation module 3 is located on one side of tethered cable reel 4; box 1 and support platform 6 form a space configured to accommodate ducted drone 7, thereby making the layout of various components in box 1 of this application embodiment reasonable, with a high degree of integration, and able to increase the flow rate of fire extinguishing agent. Compared with the superstructure of rotary-wing drone, it is smaller in size, easier to transport or place, reduces the space occupied in the width direction of box 1, and can pass through narrow spaces during transportation, improving the adaptability of the superstructure.

[0046] Optionally, the housing 1 can be used to protect the internal components.

[0047] Optionally, the fire monitor 73 is equipped with a hose connector, and the fire monitor 73 is connected to the liquid tank 2 via a hose.

[0048] Optionally, the extinguishing agent can be a mixture of water and foam, which can be mixed according to industry standards.

[0049] Optionally, the mobile equipment includes fire trucks, that is, the fire-fighting superstructure device of this application embodiment can be fixedly installed on a fire truck, so that the fire truck can drive into high-rise communities or some narrow passages to extinguish fires; the fixed equipment can include fixed platforms in the community, or some support platforms 6 of other high-rise buildings, etc. When a fire occurs nearby, it is not necessary to transport the fire-fighting superstructure device to the vicinity of the fire by fire truck. The fire-fighting superstructure device of the fixed equipment can directly control the ducted drone 7 to extinguish the fire, so that the ducted drone 7 can reach the vicinity of the fire as soon as possible and respond quickly, thereby improving efficiency.

[0050] Optionally, the power generation module 3 is configured in the generator compartment. The power generation module 3 includes a generator. The fire-fighting superstructure also includes a hydraulic cylinder. The fuel in the hydraulic cylinder is supplied to the engine through a fuel supply system. The fuel can be gasoline. The engine is driven by burning gasoline. The output shaft of the engine and the input shaft of the generator are coaxially fixed. The engine drives the generator to generate electrical energy. This electrical energy is distributed through a hybrid power control module. Depending on the actual working conditions, it can provide power to the ducted unmanned aerial vehicle 7, or it can provide energy to other components that require power.

[0051] Optionally, modules such as hydraulic cylinders and engines can be mounted on fire trucks or fixed platforms within residential areas to enable generator startup.

[0052] Optionally, the housing 1 includes four side walls and a top cover located above the side walls. The top cover can be opened by a hydraulic or electric push rod to facilitate the flight of the ducted drone 7.

[0053] As shown in Figure 3, in one embodiment, the fire-fighting superstructure includes a ducted drone 7. The ducted drone 7 is longitudinally elongated, meaning that the extension direction of the ducted drone 7 is along its own length, reducing the space occupied by the ducted drone 7 in width. This makes it easier for the fire-fighting superstructure to pass through narrow areas. Compared to areas that ladders or rotary drones cannot pass through, this increases the application scenarios of the ducted drone 7 and improves its adaptability. The ducted drone 7 is located above the liquid tank 2, and the extension direction of the ducted drone 7 is consistent with the arrangement direction of the liquid tank 2, the water pump system 5, and the mooring cable reel 4. This allows the ducted drone 7 to make full use of the space above the liquid tank 2, making the internal layout of the container 1 more reasonable and reducing the space occupied in the width direction of the container 1. This reduces the space occupied and facilitates transportation and placement.

[0054] This application uses a ducted drone 7, which has a larger payload capacity compared to a rotary-wing drone. On the one hand, it can increase the fire extinguishing altitude, and on the other hand, it can carry a larger weight of fire extinguishing agent, increasing the fire extinguishing flow rate and thus improving the fire extinguishing effect. Furthermore, with the same payload as a rotary-wing drone, the ducted drone 7 is smaller in size, which can pass through some narrow spaces, enriching the fire extinguishing scenarios and improving the fire extinguishing effect.

[0055] Optionally, under the same load, the volume of the rotary-wing UAV is larger than that of the ducted UAV 7 provided in the embodiments of this application. Therefore, the ducted UAV 7 in the embodiments of this application is small in size and designed with a longitudinal structure, which makes it easy to pass through narrow areas.

[0056] Optionally, the ducted unmanned aerial vehicle 7 is equipped with a fire monitor 73, which can be connected to the liquid tank 2, and the fire extinguishing agent in the liquid tank 2 can be sprayed through the fire monitor 73.

[0057] As shown in Figures 8 and 9, in one embodiment, the ducted unmanned aerial vehicle (UAV) 7 includes a support beam 71. At least four ducted propulsion systems 72 are provided on one side of the support beam 71. The support beam 71 provides a support structure for the ducted propulsion systems 72. The partial design of the ducts also makes the ducted UAV 7 a longitudinally elongated structure, reducing the space occupied by the ducted UAV 7 in terms of width. Using a multi-ducted UAV 7 can further improve the load capacity of the ducted UAV 7. Furthermore, by using a larger number of ducted UAVs 7, when one of the ducted propulsion systems 72 on one side of the support beam 71 fails, the other ducted propulsion systems 72 on the same side can compensate for the corresponding lift, facilitating the control of the ducted UAV 7 and improving its resilience and stability.

[0058] Optionally, for an eight-duct UAV, four ducted propulsion systems 72 are fixed on each side of the support beam 71; for a ten-duct UAV, five ducted propulsion systems 72 are fixed on each side of the support beam 71.

[0059] As shown in Figures 1 to 3, in one implementation method, the fire-fighting superstructure can be installed on a fire truck, allowing the fire truck to extinguish high-rise fires in confined spaces and improving its adaptability. The power generation module 3 can be located behind the fire truck cab, and the liquid tank 2 is located at the rear of the housing 1. Since the liquid tank 2 stores extinguishing agent and is relatively heavy, and the power generation module 3 also has a certain weight, placing the power generation module 3 behind the cab and the liquid tank 2 at the rear of the housing 1 can balance the weight of the entire fire truck and ensure stability when driving it. At the same time, the layout is reasonable and improves the space utilization of the fire truck. The mooring cable reel 4 is located behind the generator module 3, shortening the distance between them and facilitating connection between the mooring cable reel 4 and the generator module 3. The water pump system 5 is located between the mooring cable reel 4 and the liquid tank 2, which is a reasonable layout. It also shortens the distance between the water pump system 5 and the liquid tank 2, reduces the number of pipeline connections, and makes the fire-fighting superstructure compact, improving space utilization and facilitating the fire-fighting superstructure to pass through narrow areas, thereby improving fire-fighting efficiency.

[0060] As shown in Figures 5 to 7, in one embodiment, the fire-fighting superstructure also includes a lifting mechanism 8. The lifting mechanism 8 is connected to the housing 1 and the support platform 6 and is located above the liquid tank 2, improving space utilization. The lifting mechanism 8 can lift the ducted drone 7 to a height exceeding that of the housing 1, avoiding obstruction of the ducted drone 7 by the surroundings of the housing 1 and facilitating the flight of the ducted drone 7.

[0061] As one implementation, the support platform 6 is provided with multiple through holes, which allow the airflow generated by the ducted propulsion system 72 to pass through the support platform 6, reducing the disturbance of the airflow to the ducted UAV 7 and improving the stability of the ducted UAV 7 during takeoff and landing.

[0062] As shown in Figure 4, in one embodiment, the tethered cable reel 4 includes a support frame 41 and a winch 42. The winch 42 is used to wind the cable and can rotate relative to the support frame 41. The support frame 41 is also equipped with a drive motor 43 and a take-up device 44. The cable can pass through the take-up device 44 and connect to the ducted UAV 7. The support frame 41 is also equipped with a guide rod 46 and a threaded rod 45. Both the threaded rod 45 and the guide rod 46 are connected to the take-up device 44. The threaded rod 45 and the take-up device 44 can be connected by a worm gear mechanism. The drive motor 43 can drive the threaded rod 46. 5. Rotation causes the take-up device 44 to move along the threaded rod 45. At the same time, the guide rod 46 guides the take-up device 44, ensuring that the take-up opening of the take-up device 44 is always facing upwards, facilitating cable take-up and release. The take-up device 44 is slidably connected to the guide rod 46, allowing the take-up device 44 to move along the guide rod 46. The drive motor 43 can be connected to the threaded rod 45 via belt drive or other gear meshing methods. Simultaneously, the winch 42 can be driven to rotate, improving the smoothness of cable take-up and release.

[0063] As one implementation method, the cable and hose are wrapped together with a protective sleeve, which prevents the cable and hose from getting tangled in the air and improves the safety of the fire-fighting equipment.

[0064] Optionally, when the cable and water hose are wrapped together by the protective sleeve, the main body can be wound by the winch 42, while the connection points with the power generation module 3 and the liquid tank 2 can be connected separately. This way, the part of the cable and water hose that is in the air is wrapped together by the protective sleeve, which improves safety.

[0065] As shown in Figures 1 to 3, in a second aspect, embodiments of this application provide a fire truck, which includes the fire-fighting superstructure device provided in the first aspect. The power generation module 3 is located at the rear of the fire truck cab, and the liquid tank 2 is located at the rear of the body 1. Since the liquid tank 2 stores fire extinguishing agent and is relatively heavy, and the power generation module 3 also has a certain weight, placing the power generation module 3 at the rear of the cab and the liquid tank 2 at the rear of the body 1 can balance the weight of the entire fire truck and meet the stability requirements when driving the fire truck; at the same time, the layout is reasonable and improves the space utilization rate on the fire truck.

[0066] The mooring cable reel 4 is located behind the generator module 3, shortening the distance between them and facilitating connection between the mooring cable reel 4 and the generator module 3. The water pump system 5 is located between the mooring cable reel 4 and the liquid tank 2, which is a reasonable layout. It also shortens the distance between the water pump system 5 and the liquid tank 2, reduces the number of pipeline connections, and makes the fire-fighting superstructure compact, improving space utilization and facilitating the fire-fighting superstructure to pass through narrow areas, thereby improving fire-fighting efficiency.

[0067] As shown in Figure 1, in one embodiment, the fire-fighting superstructure also includes a lifting mechanism 9. The lifting system is installed on the fire truck and can be used to place the ducted drone 7 from the fire truck to the ground, or to place the ducted drone 7 from the ground onto the fire truck, which can realize the efficient movement of the ducted drone 7 and reduce the cost of manual handling.

[0068] Optionally, in some special environments, the ducted drone 7 may not be able to land accurately and directly on the lifting mechanism 8 and the support platform 6. Therefore, the ducted drone 7 can be lifted by the lifting mechanism 9 and placed on the lifting mechanism 8; or the ducted drone 7 can be lifted by the lifting mechanism 8 and placed on the ground platform by the lifting mechanism 9.

[0069] Optionally, the lifting mechanism 9 is installed at the rear of the fire truck to reduce the impact of the lifting mechanism 9 on other parts of the fire truck.

[0070] Optionally, the fire truck also includes a chassis, which primarily serves as the transport and load-bearing component for the entire fire-fighting superstructure. The fire truck is also equipped with a full-power power take-off (PTO) to provide power to the water pump system 5 during firefighting operations. A side PTO is also installed on the fire truck to provide power to the hoisting mechanism 9 and the lifting mechanism 8.

[0071] Optionally, the water pump system 5 can be located in the middle of the fire truck. The full-power power take-off on the chassis is connected to the water pump input shaft via a coupling. The water pump system 5 is controlled to deliver the high-pressure extinguishing agent through a water hose connected to the outlet of the water pump system 5 to the fire monitor 73 mounted on the ducted drone 7. Firefighters can control the fire monitor 73 from the ground to adjust the direction and intensity of the water flow to extinguish the fire.

[0072] Optionally, the fire truck is also equipped with a hydraulic system, which is connected to a side power take-off and provides power through the side power take-off. The hydraulic system can control the lifting mechanism 8 and the hoisting mechanism 9 respectively.

[0073] As shown in Figures 5 to 7, optionally, the lifting mechanism 8 includes a support base 83 located below the entire lifting mechanism 8, which supports the entire lifting mechanism 8. It also includes a first support member 81 and a second support member 82, which are arranged crosswise and rotatably connected at the intersection. One end of the first support member 81 is rotatably connected to the support base 83, and the other end is slidably connected to the support platform 6. One end of the second support member 82 is slidably connected to the support base 83, and the other end is rotatably connected to the support platform 6. In this way, the connection between the first support member 81 and the second support member 82 provides support for the first support member 81 and the second support member 82. The first support member 81 and the second support member 82 can slide relative to the support platform 6 and the support base 83, respectively. During the sliding process, the height of the support platform 6 is also adjusted accordingly, and the height of the support platform 6 will also change, thereby achieving the purpose of supporting the ducted unmanned aerial vehicle 7 and raising or lowering it.

[0074] As shown in Figure 5, optionally, the first support member 81 includes two first support arms 811, and the second support member 82 includes two second support arms 812. The two first support arms 811 are located between the two second support arms 812, thereby achieving a cross connection between the first support member 81 and the second support member 82, and also avoiding interference between the first support member 81 and the second support member 82 during sliding. The support base 83 has multiple through areas, the number of which corresponds to the number of support components. The length of the through areas is greater than that of the first support arm 811 and the second support arm 812. The length of the support arm 812 is such that when the lifting mechanism 8 is in the lowering state, the first support member 81 and the second support member 82 can be completely in the through area, avoiding interference from the support base 83 to the first support member 81 and the second support member 82. At the same time, it also prevents the first support member 81 and the second support member 82 from protruding from the support base 83. The height occupied by the lifting mechanism 8 in the lowering state is the same as the thickness of the support base 83, which can reduce the space occupied by the lifting mechanism 8 in the lowering state, further improve the space utilization, and avoid affecting the layout of other modules.

[0075] As shown in Figure 5, the support base 83 includes multiple connecting beams 831, which are arranged parallel to each other and extend along the length of the support base 83. Two adjacent connecting beams 831 are respectively provided with first grooves 8311 with openings facing each other. A roller 84 is provided at one end of the second support arm 812. The roller 84 can slide along the first groove 8311, so that the second support member 82 can slide relative to the support base 83, and at the same time adjust the height of the support platform 6.

[0076] As shown in Figure 7, optionally, the support platform 6 is provided with a longitudinal beam, which is positioned toward the support base 83 and extends along the length of the support platform 6. The longitudinal beam is provided with a second groove 61 in the direction of the frame of the support platform 6. The two frames of the support platform 6 in the length direction are also provided with a second groove 61 in the direction of the longitudinal beam. A roller 84 is provided at one end of the first support arm 811. The roller 84 can slide along the second groove 61, so that the first support member 81 can slide relative to the support platform 6, and at the same time, the height of the support platform 6 is adjusted.

[0077] As shown in Figures 5 and 7, optionally, a first driving member 85 is provided between adjacent first support arms 811 and second support arms 812. One end of the first driving member 85 is connected to the first support arm 81, and the other end is connected to the second support arm 82, with the connection position higher than the position where the first support arm 81 and the second support arm 82 are rotatably connected. The first driving member 85 has a telescopic stroke and is configured to drive the first support arm 81 and the second support arm 82 to slide relative to the support platform 6 and the support base 83, respectively. When the first driving member 85 extends, the extended end applies a force to the second support arm 82. At this time, using the lever principle, the sliding end of the second support arm 82 will slide relative to the support base 83, with the sliding direction towards the first support arm 81. Simultaneously, since the first support member 81 and the second support member 82 are rotatably connected, the first support member 81 is pushed to slide synchronously, and the first support member 81 slides towards the second support member 82 and the second support member 82 slides towards the first support member 81, so the lifting mechanism 8 is in an upward state; when the first drive member 85 retracts, it can push the first support member 81 away from the second support member 82 and push the second support member 82 away from the first support member 81, so the lifting mechanism 8 is in a downward state, thus realizing the upward or downward state of the lifting mechanism 8; in addition, the first drive member 85 is set in the gap between the adjacent first support arm 811 and second support arm 812, reducing the occupied volume and improving the space utilization rate.

[0078] As shown in Figures 5 and 7, optionally, a limiting member 86 is provided between adjacent first support arm 811 and second support arm 812. The limiting member 86 is coaxially connected to one end of the first driving member 85. When the first driving member 85 gradually extends, the second support member 82 slides toward the first support member 81, and one end of the first support member 81 slides toward the second support member 82. However, the first support member 81 and the second support member 82 must have a certain intersection angle to ensure the stability of the entire lifting mechanism 8. Therefore, when the first support member 81 and the second support member 82 slide to a certain position, the first driving member 85 can abut against the limiting member 86. The limiting member 86 restricts the first driving member 85 from continuing to extend, thereby restricting the sliding position of the first support member 81 and the second support member 82, and satisfying the stability of the lifting mechanism 8.

[0079] As shown in Figures 8 to 10, optionally, the ducted unmanned aerial vehicle (UAV) 7 includes a support beam 71 extending longitudinally, and at least three ducted propulsion systems 72 are provided on each side along the width direction perpendicular to the length direction of the support beam 71. In this way, the ducted propulsion systems 72 are arranged on the support beam 71, so that the ducted UAV 7 extends along the length direction and has a longitudinal structure, enabling the ducted UAV 7 to pass through narrow areas. At least three ducted propulsion systems 72 are provided on each side along the width direction of the support beam 71 to meet the dynamic load, and a fire monitor 73 is provided on the support beam 71. The fire monitor 73 can be connected to the water hose and can spray fire extinguishing agent, so that the ducted UAV 7 can perform high-altitude fire extinguishing.

[0080] As shown in Figure 9, optionally, four ducted propulsion systems 72 are provided on one side of the support beam 71, meaning the ducted UAV 7 of this application is an eight-ducted UAV, with three ducted propulsion systems 72 connected to the support beam 71. These three ducted propulsion systems 72 are configured as a first ducted propulsion system 721, a second ducted propulsion system 722, and a third ducted propulsion system 723. This means that three ducted propulsion systems 72 can be installed on one side of the support beam 71, thereby reducing the length of the ducted UAV 7 and improving space utilization. 722 is located between the first ducted propulsion system 721 and the third ducted propulsion system 723; another ducted propulsion system 72 is connected to the second ducted propulsion system 722 and can be folded towards the second ducted propulsion system 722 along the length direction perpendicular to the support beam 71, thereby further reducing the width of the ducted UAV 7, facilitating transportation, especially when the ducted UAV 7 is placed on a fire truck, which is beneficial for the placement of other components on the fire truck, allowing the fire truck to be made smaller in both width and length, making it easier for the fire truck to pass through narrow areas. The ducted UAV 7 of this application reduces the length dimension while meeting the power load requirements, and is also convenient for transportation and placement.

[0081] As shown in Figures 9 and 10, the ducted unmanned aerial vehicle (UAV) 7 is also equipped with a folding mechanism. By setting the folding mechanism, the ducted propulsion system 72 can be folded along its length or width, thereby reducing the space required for the ducted UAV 7 and facilitating transportation and placement. The folding mechanism includes a first connector 10 and a second connector 11 that are rotatably connected. The first connector 10 and the second connector 11 are respectively connected to the two ducted propulsion systems 72, which allows the ducted propulsion systems 72 to rotate, facilitating folding. The folding mechanism also includes a drive assembly 12, which is connected to the first connector 10 and the second connector 11. At the same time, the drive assembly 12 can drive the second connector 11 to rotate relative to the first connector 10, thereby causing the ducted propulsion system 72 connected to the second connector 11 to rotate, thus realizing the folding of the ducted propulsion system 72.

[0082] As shown in Figure 10, the first connecting member 10 has a first through hole. The driving assembly 12 includes a second driving member 121, which is located at the first through hole and rotatably connected to the first connecting member 10, allowing the second driving member 121 to rotate relative to the first connecting member 10. The second connecting member 11 has a second through hole. The driving assembly 12 also includes a rotating member 122, which is located at the second through hole and rotatably connected to the second connecting member 11, allowing the rotating member 122 to rotate relative to the second connecting member 11. The driving assembly 12 also includes a connecting rod 123, one end of which is threadedly connected to the rotating member 122, and the other end is connected to the second driving member 121. When the second driving member 121 drives the connecting rod 123 to rotate, the connecting rod 123 is threadedly connected to the rotating member 122, allowing rotation. The rotating component 122 moves toward or away from the second driving component 121. While driving the rotating component 122 to move, the rotating component 122 is also rotatably connected to the second connecting component 11, which also causes the second connecting component 11 to flip relative to the first connecting component 10, thus realizing the folding function of the ducted propulsion system 72. During the flipping process of the second connecting component 11, the driving component and the rotating component 122 need to adjust their angles in real time. Therefore, the second driving component 121 and the rotating component 122 are rotatably connected to the first connecting component 10 and the second connecting component 11, respectively. This allows the second driving component 121 to drive the rotating component 122 to rotate while adjusting their angles in real time. This enables the second driving component 121 to better drive the rotating component 122 to move on the connecting rod 123, facilitating the control of the folding mechanism and avoiding jamming.

[0083] As shown in Figure 10, the second driving member 121 is provided with a first connecting hole 1211. The second driving member 121 is rotatably connected to the first connecting member 10 through the first connecting hole 1211. In this way, the second driving member 121 can rotate about the first connecting member 10 with the first connecting hole 1211 as the axis. At the same time, the second connecting member 11 can be flipped with the connection position between the first connecting member 10 and the second connecting member 11 as the axis. The axis of the flipped position can be configured as the first axis. The axis of the first connecting hole 1211 is parallel to the first axis, and the axis of the connecting rod 123 is perpendicular to the first connecting hole 1211. Thus, when the second driving member 121 drives the connecting rod 123 to rotate, the second connecting member 11 flips, and the second driving member 121 also rotates relative to the first connecting member 10 in real time through the first connecting hole 1211, so that the second driving member 121 maintains an angle corresponding to the rotating member 122 in real time, so as to better drive the rotating member 122. The rotating member 122 is provided with a second connecting hole, and the rotating member 122 is connected to the second connecting member 10 through the second connecting hole. The connecting member 11 is rotatably connected, allowing the rotating member 122 to rotate around the second connecting member 11 with the second connecting hole as the axis. Simultaneously, the second connecting member 11 can be flipped via the connection point between the first connecting member 10 and the second connecting member 11, with the axis of the flipped position configured as the first axis. The axis of the second connecting hole is parallel to the first axis, and the axis of the connecting rod 123 is perpendicular to the second connecting hole. Thus, when the second driving member 121 drives the connecting rod 123 to rotate, the second connecting member 11 flips, and the connecting rod 123 is threadedly connected to the rotating member 122. The driving angle of the second driving member 121 changes, correspondingly causing the rotating member 122 to change its angle. The rotating member 122 also adjusts its rotation angle in real time through the second connecting hole to maintain consistency with the second driving member 121, ensuring that the second driving member 121 maintains an angle corresponding to the rotating member 122 in real time. This facilitates better driving of the rotating member 122 by the second driving member 121, further facilitating the folding function of the ducted propulsion system 72 and preventing jamming.

[0084] Optionally, the second driving component 121 can be a lead screw motor, and the connecting rod 123 can be an electric lead screw. The lead screw motor is connected to the electric lead screw and can drive the electric lead screw to rotate. The first connecting hole 1211 can be formed on the housing of the lead screw motor, or the second driving component 121 can also include a housing connected to the lead screw motor to avoid the first connecting hole 1211 affecting the normal operation of the lead screw motor.
