[0020] Forest fires, as a global ecological disaster, are characterized by their suddenness, destructive power, and rapid spread. Traditional firefighting methods are limited by terrain and have insufficient response speed, making them unsuitable for fighting complex fires. In recent years, drone technology, with its mobility and real-time capabilities, has gradually become an important tool in the field of forest firefighting. However, existing vehicle-mounted drone firefighting devices still face many technical bottlenecks in practical applications, and there is an urgent need to improve their overall performance through mechanical structural innovation.

[0021] Early vehicle-mounted drone firefighting systems mostly used simple modification schemes:

[0022] Basic transportation function: Fire trucks are only used as drone transportation tools. The drones need to be assembled and prepared for takeoff manually. The overall deployment process is not fundamentally different from ground operations.

[0023] Fixed launching mechanism: Some devices are equipped with sliding rails or catapults on the roof, but the launching angle and distance are fixed, which cannot adapt to the dynamic changes in the fire scene.

[0024] Single payload configuration: The drone carries only a single type of fire extinguishing agent and needs to return to change the module, which may cause the best time to fight the fire to be missed in actual combat.

[0025] While such solutions achieve a preliminary integration of drones and vehicles, they fail to address the core pain points of "rapid deployment, efficient operation, and intelligent recycling." In essence, they are simply an overlay of "vehicle-mounted + drone" rather than a systematic integration.

[0026] To enhance combat effectiveness, recent research has focused on mechanized deployment mechanisms:

[0027] Hydraulic lifting platform: The launch altitude of the drone can be adjusted through the hydraulic system to adapt to different terrains, but the lifting process takes a long time and the hydraulic components are easily affected by the high temperature of the fire.

[0028] Chain-driven launch device: The UAV is driven by a chain to move along the track, which improves the launch speed, but the chain wear rate is high and the maintenance cost increases significantly.

[0029] Preliminary application of electromagnetic catapults: Some high-end devices have introduced electromagnetic catapult technology to accelerate drones to takeoff speed using electromagnetic force, but the catapult trajectory is fixed and the launch direction cannot be adjusted.

[0030] While the aforementioned innovations have made progress in deployment speed and adaptability, they still suffer from problems such as "single-point optimization and lack of system integration," failing to form a complete "storage-launch-recovery-resupply" closed loop.

[0031] Deployment efficiency bottleneck

[0032] Excessive human intervention: From drone assembly and parameter setting to launch preparation, operators need to complete multiple steps, and the time taken for a single deployment far exceeds the golden period for fire fighting in the early stages of a fire.

[0033] Poor inter-mechanical coordination: The launch platform, lifting mechanism, and catapult device are mostly independently controlled and need to be adjusted one by one, making it difficult to meet the practical needs of "one-click deployment".

[0034] Poor environmental adaptability: Existing launch mechanisms are mostly designed for flat terrain. In complex terrains such as mountains and forests, the stability of UAV take-off and landing is greatly reduced.

[0035] Load switching and resupply dilemma

[0036] Low modularity: Switching between fire extinguishing agent types and reconnaissance equipment requires manual disassembly and reassembly, which is cumbersome and easily damages precision components.

[0037] Delayed energy supply: Short battery life, and the limited range of movement due to cable dragging of tethered power supply, requiring frequent return to recharge for long-term operations, which affects continuous combat capability.

[0038] Lack of intelligent identification: It cannot automatically select the optimal load based on the fire situation, relying on manual judgment, which easily leads to the phenomenon of "equipment mismatch with fire situation".

[0039] Environmental adaptation and stability challenges

[0040] Insufficient wind resistance: Fires are often accompanied by strong winds, and existing drones are prone to deviating from their flight paths in winds of force 6 or above, resulting in a significant decrease in spraying accuracy.

[0041] Inadequate high-temperature protection: Key components such as engines and batteries lack effective heat insulation measures, resulting in a significantly higher failure rate in the high-temperature environment of a fire.

[0042] Poor takeoff and landing stability: In complex terrain, drones are prone to overturning when landing due to uneven ground, resulting in a high loss rate during the recovery process.

[0043] Shortcomings of cluster collaboration technology

[0044] Limitations of single-unit operation: A single drone has a small coverage area, and multi-drone collaboration requires complex communication relays. It is also prone to losing contact in mountainous areas or other areas with signal obstruction.

[0045] Inefficient task allocation: Due to the lack of intelligent scheduling algorithms, when multiple machines execute tasks, there is a tendency for overlapping or missed areas, resulting in low resource utilization.

[0046] Data sharing lag: Insufficient real-time information from the fire scene, high data transmission delay between the main control drone and subordinate drones, affecting the timeliness of decision-making.

[0047] The necessity of breakthroughs in key technologies

[0048] (I) Practical needs drive technological innovation

[0049] Forest fires are characterized by "hidden initial outbreaks, rapid spread, and short windows for firefighting," requiring firefighting equipment to have "minute-level response and hour-level continuous operation capabilities." The shortcomings of existing vehicle-mounted drone devices in terms of deployment speed, endurance, and environmental adaptability directly restrict their application effectiveness in the core areas of fire zones.

[0050] (II) The need for systemic integrated innovation

[0051] Single technology optimization (such as faster launch or more powerful motors) cannot solve the fundamental problem. It is necessary to build a closed-loop system covering the entire process of "storage-launch-recovery-replenishment-coordination" through multi-dimensional integrated innovation of "mechanical structure-control system-energy management".

[0052] (III) Guiding Industry Technology Development Trends

[0053] With the development of artificial intelligence, new materials, and high-precision manufacturing technologies, drone-based firefighting equipment is evolving from "functional" to "intelligent and integrated." As an important carrier for drones, the mechanical structure design of vehicle-mounted platforms needs to be deeply integrated with drone technology, rather than simply superimposed.

[0054] Future technological development direction

[0055] (I) Full-process mechanization integration

[0056] "One-click deployment" system: Through a multi-level sliding platform and electric clamping mechanism, it enables fully automatic adjustment of the drone from storage to launch.

[0057] Intelligent recovery network: Combining visual positioning and damping buffer technology, it improves the landing accuracy of drones and reduces recovery losses.

[0058] (II) Innovation in Environmental Adaptive Technologies

[0059] Variable-form landing gear: Made of carbon fiber and biomimetic structure, it can dynamically adjust the length and stiffness of the landing gear to adapt to different terrains.

[0060] Wind-resistant stabilization system: integrates dynamic balance blades and wind speed sensors to counteract crosswind interference through real-time attitude adjustment.

[0061] (III) Intelligent Management of Energy and Load

[0062] Wireless fast charging technology: A high-power wireless charging module is embedded in the vehicle platform, which, combined with fuel cells, enables long-term driving range.

[0063] Modular intelligent switching: Through RFID identification and central controller, the load type is automatically switched according to the fire situation requirements.

[0064] (iv) Optimization of Cluster Collaboration Algorithm

[0065] 5G communication relay: The main control drone is equipped with a micro base station to build a dedicated communication network for the fire scene, ensuring real-time data sharing among multiple drones.

[0066] Task allocation engine: Based on the A* algorithm and 3D fire scene model, it dynamically optimizes the drone path to avoid duplicate operations.

[0067] The technological development of vehicle-mounted unmanned aerial vehicle (UAV) forest fire emergency rescue devices has evolved from "functional superposition" to "partial integration." While existing technologies have made significant progress in deployment efficiency, environmental adaptability, energy management, and cluster collaboration, issues such as systemic deficiencies, lack of intelligence, and limited reliability remain. In the future, breakthroughs in areas such as full-process mechanization integration, environmental adaptive technology innovation, intelligent energy and payload management, and optimized cluster collaboration algorithms are expected to meet the practical requirements of "minute-level response, hour-level continuous operation, and full-scenario coverage," providing more efficient and reliable equipment support for forest fire fighting.

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.

[0069] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0070] Reference Figure 1-Figure 2As shown, this embodiment provides a vehicle-mounted drone forest fire fighting emergency rescue device, including a vehicle body 1, a compartment 2 on the vehicle body 1, an opening 4 on the side of the compartment 2 away from the front of the vehicle, first slide grooves 3 symmetrically arranged on both sides of the compartment 2, a sliding mechanism in the first slide groove 3, the sliding mechanism including a first connecting seat 5 slidably connected in the first slide groove 3, a first connecting plate 6 slidably connected between the two first connecting seats 5, a drone body 7 on the first connecting plate 6, a first driving mechanism in the compartment 2, the first driving mechanism being drivenly connected to the first connecting plate 6, and multiple limiting mechanisms on the first connecting plate 6.

[0071] The vehicle body 1 serves as a mobile platform, and sliding mechanisms are installed in the first sliding grooves 3 on both sides of the carriage 2. A first connecting seat 5 slides longitudinally along the first sliding groove 3, and a first connecting plate 6 slides longitudinally between the two first connecting seats 5. A first driving mechanism drives the first connecting plate 6 to move, pushing the drone from the storage position to the launch position. A limiting mechanism constrains the drone's position during movement to prevent swaying. This invention enables precise positioning and movement of the drone within the carriage 2; the limiting mechanism ensures the drone's stability during movement, avoiding collision damage.

[0072] Further optimization of the design: first legs 8 are symmetrically fixed to both sides of the drone body 7, and second legs 9 are fixed to the bottom of the two first legs 8 on the same side of the drone body 7. The second legs 9 are located on the top surface of the first connecting plate 6, and limiting mechanisms are provided on both sides of the second legs 9.

[0073] The first leg 8 on each side of the drone is fixed to the second leg 9, and the second leg 9 directly contacts the first connecting plate 6. The limiting mechanism clamps the second leg 9 from both sides, and the clamping force is adjusted by sliding the third connecting seat 12. The first drive unit provides power, enabling the limiting mechanism to adapt to drone legs of different sizes. The leg structure simplifies the drone fixing method and reduces the number of parts; the limiting mechanism clamps from both sides, improving fixing stability.

[0074] The scheme is further optimized. The limiting mechanism includes a second connecting seat 10 fixed to the top surface of the first connecting plate 6. The bottom surface of the second connecting seat 10 is provided with a second sliding groove 11. A third connecting seat 12 is slidably connected in the second sliding groove 11. The side of the third connecting seat 12 near the second support leg 9 is provided with a third sliding groove 20. The second support leg 9 is slidably connected in the third sliding groove 20. The side of the third connecting seat 12 away from the second support leg 9 is drivenly connected to a first driving part. The first driving part is fixedly connected to the top surface of the first connecting plate 6.

[0075] The second connecting seat 10 is fixed to the first connecting plate 6, and the third connecting seat 12 slides along the second slide groove 11; the second support leg 9 is embedded in the third slide groove 20, and the clamping gap is adjusted when the third connecting seat 12 moves; the first drive unit drives the third connecting seat 12 through the first lead screw 16 to realize electric clamping or release.

[0076] In a further optimized design, the first drive unit includes a fourth connecting seat 14 fixed to the top surface of the first connecting plate 6. A first motor 15 is fixed to the top surface of the fourth connecting seat 14. A first lead screw 16 is fixed to the output shaft of the first motor 15. The first lead screw 16 is located in the second slide groove 11. The side of the first lead screw 16 away from the first motor 15 is threadedly connected to the third connecting seat 12.

[0077] The first motor 15 drives the first lead screw 16 to rotate. The first lead screw 16 is threadedly engaged with the third connecting seat 12, which is converted into linear motion of the third connecting seat 12 to precisely control the clamping gap.

[0078] Further optimization of the scheme: the first drive mechanism includes a fifth connecting seat 17 fixedly connected inside the carriage 2, a second motor 18 fixedly connected to the top surface of the fifth connecting seat 17, a second lead screw 19 fixedly connected to the output shaft of the second motor 18, and the end of the second lead screw 19 away from the second motor 18 being threadedly connected to the first connecting plate 6.

[0079] The second motor 18 drives the second lead screw 19 to rotate. The second lead screw 19 is threadedly engaged with the first connecting plate 6, pushing the first connecting plate 6 to move longitudinally along the first slide groove 3 and the third slide groove 20.

[0080] In a further optimized design, a third slide 20 is provided on the top surface of the first slide 3, and a first limiting plate 21 is fixedly connected to the top surface of the first connecting seat 5. The first limiting plate 21 is slidably connected within the third slide 20.

[0081] The third slide 20 at the top of the first slide 3 constrains the movement path of the first limiting plate 21; the first limiting plate 21 is fixedly connected to the first connecting seat 5 to prevent the first connecting seat 5 from falling out of the slide during sliding; the width of the third slide 20 is 1mm larger than that of the first limiting plate 21, taking into account both guidance and assembly tolerance.

[0082] In a further optimized design, the first connecting seat 5 is provided with a fourth sliding groove 22 on the side near the first connecting plate 6, and the first connecting plate 6 is slidably connected in the fourth sliding groove 22.

[0083] The fourth slide groove 22 on the side of the first connecting seat 5 constrains the longitudinal movement of the first connecting plate 6; the first connecting plate 6 is embedded in the fourth slide groove 22 and slides in the fifth slide groove 24 through the second limiting plate 25, further restricting the direction of movement; the limiting block 23 at the end of the fourth slide groove 22 prevents the first connecting plate 6 from moving excessively.

[0084] In a further optimized design, a limiting block 23 is fixedly connected to the side of the fourth slide 22 near the first drive mechanism, and a fifth slide 24 is provided on the top surface of the fourth slide 22. A second limiting plate 25 is symmetrically fixed to the top surface of the first connecting plate 6, and the second limiting plate 25 is slidably connected in the fifth slide 24.

[0085] The limiting block 23 at the end of the fourth slide 22 contacts the first connecting plate 6 when it moves to the limit position; the second limiting plate 25 in the fifth slide 24 moves synchronously, and when it approaches the limiting block 23, the second motor 18 receives the limit signal and stops running.

[0086] Further optimization of the design involves installing wings 26 at the four corners of the drone body 7, and installing a fire extinguishing grenade release ring 27 at the bottom of the drone body 7.

[0087] The wings 26 provide lift to propel the drone in flight; the fire extinguishing bomb release ring 27 is located at the bottom and throws the fire extinguishing bombs via an electronic triggering device; the charging mechanism 28 automatically docks after the drone lands and replenishes its power through wireless charging or contact charging.

[0088] To further optimize the design, a charging mechanism 28 is installed inside carriage 2 near the front of the train.

[0089] The charging mechanism 28 is installed at the front of the vehicle compartment 2 and includes a wireless charging pad or charging contacts; when the drone lands, it aligns with the charging interface through a visual positioning system and automatically adjusts its position to complete charging.

[0090] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0091] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
