Description

Technical Field

[0001] The present invention relates to the technical field of high-altitude atomizing unmanned aerial vehicles, and particularly relates to a high-altitude atomizing unmanned aerial vehicle with high efficiency atomization and a using method thereof. Background Technique

[0002] The plateau fog-spreading drone is a drone equipment designed for the special environment of high altitude areas. It is used for fog-spreading operations in agriculture, forestry and other fields. In view of the characteristics of thin air at high altitudes, it is equipped with a high-power flight system to provide the drone with strong lifting force, enabling it to fly stably in plateau areas and overcome the impact of environmental factors such as low air pressure and low oxygen on flight performance. It can carry a certain amount of medicine and convert the liquid medicine into fine smoke particles for spraying through the fog-spreading mechanism. These smoke particles are usually smaller than 50 microns and have good suspension and diffusion properties. They can last for up to one hour in windless conditions, and are resistant to rain erosion and have long-lasting efficacy. They can play a better role under complex plateau meteorological conditions. Good prevention and control effect, the use of advanced navigation and positioning systems, combined with high-precision spraying control technology, can achieve precise positioning and precise spraying, ensure that the agent is evenly covered in the target area, improve the utilization rate of the agent, reduce waste and pollution to the environment, have good wind resistance, low temperature resistance, UV resistance and other properties, can adapt to the changeable climatic conditions and complex geographical environment in the plateau area, at the same time, the fuselage structure is sturdy and durable, with certain shock and impact resistance to ensure stable operation in harsh environments, such as the Chinese utility model provides an atomizing spray device based on agricultural plant protection drones and its use method, patent number: CN116605427B, including a body and multiple The rotor has a liquid tank and a high-pressure pump mounted on the body, a downward-facing nozzle is mounted under the rotor, the nozzle is tilted in a direction away from the center line of the body, and also includes a wind measuring mechanism and a distribution mechanism. The wind measuring mechanism includes a support shell and a horizontal bottom plate located in the support shell, the center of the bottom plate is fixedly connected to a support rod extending upward, the upper end of the support rod is fixedly connected to a hollow ball for detecting wind direction and wind force, the distribution mechanism distributes the high-pressure liquid output by the high-pressure pump to all the nozzles, and the distribution mechanism automatically adjusts each nozzle according to the wind direction and wind force detected by the wind measuring mechanism, thereby reducing the change of the spraying path caused by the lateral wind, so as to increase the working width. The invention has short dynamic response time, fast adjustment, simple structure, and saves liquid medicine. The promotion of drones for pesticide spraying plays a positive role, but the existing plateau mist drones do not have the function of adjusting the nozzles at multiple angles and directions. In complex plateau terrain and diverse crop planting environments, such as mountains, hills or irregular farmland shapes, as well as fruit trees, tall crops and other plants of different heights and shapes, the nozzles that cannot be adjusted are difficult to flexibly spray the liquid medicine evenly to every corner and different parts, and spraying dead angles are prone to occur, resulting in some areas being unable to be effectively protected, affecting the pest control effect or fertilization effect. Different plateau crops have different requirements for the spraying angle and direction of the liquid medicine. For example, low-lying crops such as barley may require the nozzle to be tilted downward for close-range precise spraying;For tall trees such as poplars, the nozzles may need to spray upward or at multiple angles so that the liquid can cover all parts of the tree canopy. The lack of nozzle adjustment function makes it difficult to meet the special needs of these different crops, reducing the versatility and operation effect of drones. Summary of the invention

[0013] A method for using a high-efficiency atomizing plateau misting drone. Before performing plateau misting operations, the operator needs to first conduct a comprehensive inspection of the drone body to ensure that its power system, flight control system and various components in the working box are in normal condition, and inject the liquid required for atomization spraying into a liquid storage device connected to the nozzle in the working box. After preparation, a command is sent through the ground control terminal, the drone body starts and carries the working box to rise steadily. After arriving above the operating area, the electric telescopic rod is started first, and the electric telescopic rods on both sides of the top of the working box cavity are connected through the output end. The bracket pushes the slip ring outward. As the slip ring is set on the light rod, under the action of thrust, the slip ring slides smoothly along the positive surface of the light rod. As the slip ring moves, the fixed plate connected to it also moves down synchronously, thereby driving the bottom support rod and support plate to slowly descend. In this process, the electric telescopic rod can adjust the nozzle to the most suitable working height from the ground by accurately controlling the telescopic length according to actual operation needs, creating good conditions for subsequent misting operations. When the nozzle height is adjusted in place, the second motor starts to run. The second motor is installed at the bottom of the support plate, and its output end The fixed gear rotates at high speed. Since the gear and the tooth plate are meshed with each other, the rotation of the gear will drive the tooth plate to move in the horizontal direction. The end of the tooth plates close to each other is fixedly installed with the frame through the bracket. Therefore, the movement of the tooth plate will drive the frame to slide in the horizontal direction together, thereby realizing the precise adjustment of the horizontal position of the nozzle. After the adjustment of the horizontal position of the nozzle is completed, the first motor is started. The first motor is fixedly installed on one side of the frame. The driving wheel at its output end begins to rotate. The driving wheel is connected to the driven wheel through a belt. When the driving wheel rotates, the belt will move accordingly, thereby driving the driven wheel to rotate synchronously. The rotating shaft fixed on the inner surface of the driven wheel will also rotate. The connecting bracket connected to the positive surface of the rotating shaft and the nozzle at the bottom will rotate around the rotating shaft. The first motor accurately controls the speed and rotation angle, which can further optimize the spraying angle of the nozzle, making the spraying of the atomized liquid more uniform and comprehensive. When the entire misting operation task is completed, the electric telescopic rod shrinks in the opposite direction, pulling the slip ring to slide upward along the light rod, driving the nozzle, connecting bracket and other components to rise and reset. Subsequently, the drone body returns according to the predetermined route, and the entire operation process ends.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Through the above technical solutions, the present invention solves the problem that existing high-altitude atomizing drones do not have the function of adjusting the nozzle at multiple angles and in multiple directions. In complex high-altitude terrains and diverse crop planting environments, such as in mountainous areas, hilly areas, or farmlands with irregular shapes, as well as plants with different heights and forms such as fruit trees and tall-stemmed crops, the non-adjustable nozzles are difficult to flexibly spray the liquid medicine evenly into every corner and different parts, easily resulting in spraying dead angles, causing some areas to be unable to be effectively protected, affecting the control effect of pests and diseases or the fertilization effect. Different high-altitude crops have different requirements for the spraying angle and direction of the liquid medicine. For example, low-growing crops such as highland barley may require the nozzle to tilt downward for precise spraying at close range; while for tall trees such as poplars, the nozzle may need to spray upward or at multiple angles so that the liquid medicine can cover all parts of the tree crown. Without the nozzle adjustment function, it is difficult to meet the special needs of these different crops, reducing the versatility and operation effect of the drone.

Without the nozzle adjustment function, it is difficult to meet the special needs of these different crops, reducing the versatility and operation effect of the drone.

[0034] A method for using a high-efficiency atomizing plateau mist-spreading drone. Before performing a plateau mist-spreading operation, the operator needs to first conduct a comprehensive inspection of the drone body 1 to ensure that its power system, flight control system and various components in the working box 5 are in normal condition, and inject the liquid required for atomization spraying into a liquid storage device connected to the nozzle 12 in the working box 5. After being ready, a command is sent through a ground control terminal, and the drone body 1 is started and carries the working box 5 to rise steadily. After arriving above the operating area, the electric telescopic rod 27 is started first, and the electric telescopic rods 27 on both sides of the top of the inner cavity of the working box 5 push the slip ring 25 outward through the bracket connected to the output end. Since the slip ring 25 is sleeved on the polished rod 28, under the action of thrust, the slip ring 25 slides smoothly along the front surface of the polished rod 28. As the slip ring 25 moves, the fixed plate 26 connected thereto also moves downward synchronously, thereby driving the bottom support rod 19 and the support plate 16 to slowly descend. In this process, the electric telescopic rod 27 can adjust the nozzle 12 to the most suitable working height from the ground by accurately controlling the telescopic length according to actual operation requirements, thereby creating good conditions for subsequent misting operations. When the height of the nozzle 12 is adjusted in place, the second motor 20 starts to run. The second motor 20 is installed at the bottom of the support plate 16, and the gear 8 fixed at its output end is rotated accordingly. The gear 8 and the toothed plate 7 are meshed with each other, and the rotation of the gear 8 drives the toothed plate 7 to move in the horizontal direction. The end of the toothed plate 7 that is close to each other is fixedly installed with the frame 9 through the bracket. Therefore, the movement of the toothed plate 7 drives the frame 9 to slide in the horizontal direction, thereby realizing the precise adjustment of the horizontal position of the nozzle 12. After the adjustment of the horizontal position of the nozzle 12 is completed, the first motor 10 is started. The first motor 10 is fixedly installed on one side of the frame 9, and the driving wheel 11 at its output end starts to rotate. The driving wheel 11 is connected to the driven wheel 17 through the belt 18. When the driving wheel 11 rotates, the belt 18 will move accordingly, thereby driving the driven wheel 1 7 rotates synchronously, the rotating shaft 23 fixed on the inner surface of the driven wheel 17 will also rotate, and the connecting bracket 24 connected to the front surface of the rotating shaft 23 and the nozzle 12 at the bottom will rotate around the rotating shaft 23. The first motor 10 accurately controls the speed and the rotation angle, which can further optimize the spraying angle of the nozzle 12, so that the spraying of the atomized liquid is more uniform and comprehensive. When the entire misting operation task is completed, the electric telescopic rod 27 contracts in the reverse direction, pulling the slip ring 25 to slide upward along the light rod 28, driving the nozzle 12, the connecting bracket 24 and other components to rise and reset. Subsequently, the drone body 1 returns according to the predetermined route, and the entire operation process ends.

During this process, the electric telescopic rod (27) can adjust the nozzle (12) to the most suitable working height from the ground by accurately controlling the telescopic length according to actual operation requirements, thereby creating good conditions for subsequent misting operations. When the height of the nozzle (12) is adjusted to the right position, the second motor (20) starts to operate. The second motor (20) is installed at the bottom of the support plate (16), and the gear (8) fixed at its output end rotates at a high speed. Since the gear (8) is connected to the toothed plate (7), The gears (8) mesh with each other, and the rotation of the gears (8) drives the toothed plate (7) to move in the horizontal direction. The ends of the toothed plates (7) that are close to each other are fixedly mounted on the frame (9) through a bracket, so the movement of the toothed plate (7) drives the frame (9) to slide in the horizontal direction together, thereby realizing the precise adjustment of the horizontal position of the nozzle (12). After the adjustment of the horizontal position of the nozzle (12) is completed, the first motor (10) is started. The first motor (10) is fixedly mounted on one side of the frame (9), and the driving wheel (11) at its output end starts to rotate. The driving wheel (11) is connected to the driven wheel (17) through a belt (18). When the driving wheel (11) rotates, the belt (18) moves accordingly, thereby driving the driven wheel (17) to rotate synchronously. When the driven wheel (17) rotates, the rotating shaft (23) fixed on the inner surface of the driven wheel (17) will also rotate, and the connecting bracket (24) connected to the front surface of the rotating shaft (23) and the nozzle (12) at the bottom will rotate around the rotating shaft (23). The first motor (10) can accurately control the rotation speed and the rotation angle, so that the spraying angle of the nozzle (12) can be further optimized, so that the spraying of the atomized liquid is more uniform and comprehensive. When the entire misting operation task is completed, the electric telescopic rod (27) contracts in the opposite direction, pulling the slip ring (25) to slide upward along the light rod (28), driving the nozzle (12), the connecting bracket (24) and other components to rise and reset, and then the drone body (1) returns according to the predetermined route, and the entire operation process ends.
