[0031] The second guide fin 55 includes an adjustment disc 54 with a groove at the bottom, and an embedded housing 551 is fixedly installed inside the groove; a second magnetic shielding sleeve 552 is fixedly installed inside the embedded housing 551, and a buffer plate 553 is glued and fixed to the top of the second magnetic shielding sleeve 552; elastic members 554 with a reset function are fixedly installed on the left and right sides of the top of the second magnetic shielding sleeve 552, and the elastic members 554 are fixedly installed on the left and right sides of the bottom of the spoiler 555; the interior of the second magnetic shielding sleeve 552 is divided into three layers of cavities: left, middle, and right, and a second coil 556 is fixedly installed inside the left and right cavities of the second magnetic shielding sleeve 552; a magnetic shielding material is fixedly provided in the middle cavity of the second magnetic shielding sleeve 552, and a single controller 557 is fixedly installed inside the middle side of the magnetic shielding material.

[0032] The transmission assembly 56 includes a driven gear 561 meshing with the side of the driving gear 52, and the driven gear 561 is fixedly mounted on the top of the pulley 562 by welding; an electromagnetic clutch 563 is fixedly installed in the center hole of the pulley 562, and the bottom plate of the electromagnetic clutch 563 is fixedly installed on the top of the connecting rod 564; an eddy current generator 565 is fixedly installed in the bottom of the connecting rod 564; and a transmission belt 566 is driven on the outside of the pulley 562.

[0033] The first guide fin 43 and the second guide fin 55 have the same overall structure, and the spoilers 555 are arranged in an alternating array.

[0034] The single controller 557 integrates a wireless communication module, which is used to receive instructions from the central processing unit of the UAV body 1 and independently control the on / off state and current intensity of the corresponding second coil 556, so that the spoiler 555 can be dynamically deflected under the action of the reset force of the elastic element 554 and the electromagnetic force.

[0035] The surface of the spoiler 555 is covered with a nickel-based high-temperature alloy coating, and the surface of the coating is provided with a micro-groove array, which is filled with polytetrafluoroethylene hydrophobic material.

[0036] Example 2:

[0037] Please see Figures 1-7This invention provides a high-efficiency firefighting drone with anti-interference capabilities. Compared to Embodiment 1, this embodiment further includes: an anti-turbulence structure 4 comprising a heat-insulating shell 41 bolted to the bottom side of the connecting arm 2; a vibration sensor 42 bolted to the side of the heat-insulating shell 41, and a first guide fin 43 at the bottom of the heat-insulating shell 41. A first magnetic shielding sleeve 44 bolted to the inside of the heat-insulating shell 41; first coils 45 bolted to the left and right sides of the first magnetic shielding sleeve 44, and a magnetorheological fluid 46 disposed inside the first magnetic shielding sleeve 44; a copper-nickel alloy nanowire mesh for electromagnetic barrier is disposed on the surface of the heat-insulating shell 41; the magnetorheological fluid 46 is specifically composed of a mixture of carbonyl iron powder and silicone oil-based carrier fluid.

[0038] The working principle of a high-efficiency firefighting drone with anti-interference capabilities, as described above, is as follows:

[0039] First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation.

[0040] Secondly, the servo motor 51 drives the active gear 52 and the driven gear 561 to mesh and transmit power. At the same time, the driven gear 561 drives multiple pulleys 562 to rotate synchronously through the transmission belt 566. During the rotation of the pulleys 562, the electromagnetic clutch 563 is energized and fixed, which drives the connecting rod 564 and the eddy current generator 565 at its bottom to rotate synchronously. The eddy current generator 565 improves flight performance by controlling airflow separation. Meanwhile, since the regulating disk 54 is located on the bottom side of the UAV body 1, the surface temperature of the UAV body 1 increases rapidly during the flight of the UAV body 1 over the fire. The regulating disk 54 provides high temperature protection for the bottom side of the UAV body 1. The internal temperature of the regulating disk 54 is detected by the temperature sensor 53. At the same time, the current of the second coil 556 on one side of the second magnetic sleeve 552 is increased by the single controller 557 at the bottom of the regulating disk 54, so that the spoiler 555 tilts upward to turbulent the airflow.

[0041] Third, when the main body of the drone 1 flies over the airspace surrounding the fire, it vibrates due to the airflow from the fire. When the vibration sensor 42 at the bottom of the connecting arm 2 detects the mechanical vibration caused by turbulence, the central processing unit of the drone 1 analyzes the vibration frequency. If it is a low-frequency vibration, an adjustable current is supplied to the first coil 45, causing the viscosity of the magnetorheological fluid 46 in the first magnetic shielding sleeve 44 to increase rapidly, converting the vibration kinetic energy into heat energy for dissipation and reducing the amplitude by 60%. If it is a high-frequency vibration, the first guide is activated. The single-unit controller 557 in the flow fin 43 increases the current of the second coil 556 on one side of the second magnetic shielding sleeve 552. The electromagnetic force compresses the elastic element 554, driving the spoiler 555 to tilt upward at a certain angle, breaking the separation vortex below the rotor 3. At the same time, the hydrophobic polytetrafluoroethylene material in the microgroove prevents water mist condensation, ensuring aerodynamic efficiency. When the airflow is stabilized, the current is reduced, and the elastic element 554 resets to restore the spoiler 555 to the horizontal position, reducing wind resistance, thereby maintaining flight stability in the high temperature, strong turbulence and electromagnetic interference environment of the fire scene.

[0042] This invention provides an improved, high-efficiency firefighting drone with anti-interference capabilities. By integrating active vibration suppression, intelligent airflow control, and high-temperature protection technologies, it breaks up eddies at the source of high-frequency vibrations through an active spoiler 555. It automatically switches to the optimal vibration reduction mode based on the vibration frequency and resets the spoiler 555 when the airflow is stable to minimize wind resistance. A dedicated adjustment disk 54 provides a physical heat insulation barrier for the bottom of the drone body 1, and works with a temperature sensor 53 to achieve thermal management. It also optimizes the overall aerodynamic performance by combining with an eddy current generator 565. The hydrophobic polytetrafluoroethylene material in the microgrooves of the spoiler 555 effectively prevents water mist condensation and ensures the performance of key aerodynamic surfaces.
