Description

Technical Field

[0001] This utility model relates to the field of wind-resistant agricultural drone technology, and in particular to a wind-resistant irrigation drone for agricultural use. Background Technology

[0002] With the continuous advancement of smart agriculture, agricultural drones have been widely used in farmland spraying, irrigation, and fertilization, offering significant advantages such as high efficiency, wide coverage, and low labor intensity. However, existing agricultural drones are easily affected by natural environmental factors, especially wind, in actual outdoor operations. Particularly under conditions of high wind speed or frequent changes in wind direction, they often experience problems such as unstable flight attitude, spray deviation, and flight path deviation, seriously affecting the quality and safety of operations.

[0003] Currently, most common wind-resistant designs rely on attitude adjustment algorithms of flight control systems or enhance the ability to resist wind by increasing motor thrust. However, most existing UAV structures are not equipped with independent wind speed and direction detection devices, lacking real-time perception of the wind field and the ability to guide local airflow, making it difficult to achieve active response and control of wind disturbances at the structural level. Utility Model Content

[0004] Based on this, it is necessary to address the problem that current common wind-resistant designs rely heavily on attitude adjustment algorithms of flight control systems or enhance wind resistance by increasing motor thrust. However, most existing UAV structures lack independent wind speed and direction detection devices, resulting in a lack of real-time wind field perception and local airflow guidance capabilities, making it difficult to achieve proactive response control to wind disturbances at the structural level. Therefore, a wind-resistant irrigation UAV for plant protection is provided, comprising: wing frames fixedly mounted on both sides of the UAV body, with rotors mounted on one side of each wing frame, and a tail fin fixedly mounted on the outer side of the UAV body; a wind-resistant mechanism, used to increase wind resistance during UAV use, is located on the outer side of the rotors; wherein the wind-resistant mechanism includes a fixed shell fixedly mounted on the opposite side of the two wing frames, a detection component is located on the outer side of the fixed shell, and an adjustment component is located between the fixed shell and the rotors.

[0005] The detection assembly includes a rotating seat rotatably mounted on the top of a fixed housing, a wind cup fixedly mounted on the top of the rotating seat, and multiple air guide plates fixedly mounted on the outer side of the wind cup.

[0006] The wind cup has a rotating guide ring installed inside, and a guide vane is fixedly installed inside the guide ring. A rotation sensor is fixedly installed inside the wind cup, and the output end of the rotation sensor is fixedly connected to the guide vane.

[0007] Multiple air guide plates are arranged in a ring around one side of the air cup, and the fixing shell is spherical.

[0008] The drone body is fixedly mounted with legs at the bottom, and a camera is fixedly mounted on one side of each leg.

[0009] The adjustment assembly includes a mounting plate fixedly installed between the wing frame and the fixed shell. A motor is fixedly installed on one side of the mounting plate. An adjustment shell is rotatably installed inside the fixed shell. The output end of the motor is fixedly connected to the outside of the adjustment shell.

[0010] The rotor is located at the bottom of the regulating shell, and the rotor is fixedly connected to the bottom of the regulating shell.

[0011] The two sides of the rotor are fixedly connected to the inside of the fixed shell by telescopic straps, which are set in an arc shape.

[0012] Beneficial effects

[0013] 1. During use, the detection component can sense the wind force and direction of the UAV in real time. When the wind force is strong or the wind direction changes suddenly, the adjustment component works in conjunction to automatically adjust the rotor angle to deflect it to the windward angle that adapts to the current wind direction, thereby forming a compensating aerodynamic force, improving the flight stability of the UAV in crosswinds and gusts, and reducing the risk of flight path deviation and attitude disturbance.

[0014] 2. Driven by a motor, the adjustment shell can rotate inside the fixed shell, thereby indirectly adjusting the angle of the rotor connected to it. It can be adjusted in conjunction with the wind speed and direction detection results to make the rotor deflect to the optimal windward angle to adapt to the current wind direction.

[0027] The following is combined Figures 1-4 This invention describes a wind-resistant irrigation drone for plant protection.

[0028] In one embodiment, a wind-resistant irrigation drone for plant protection includes: wing frames 110 fixedly mounted on both sides of the drone body 100, rotors 200 provided on one side of each of the two wing frames 110, and a tail fin 120 fixedly mounted on the outer side of the drone body 100; a wind-resistant mechanism 300, used to increase wind resistance when the drone body 100 is in use, is provided on the outer side of the rotors 200; wherein the wind-resistant mechanism 300 includes a fixed shell 310 fixedly mounted on the opposite side of the two wing frames 110, a detection component 320 provided on the outer side of the fixed shell 310, and an adjustment component 330 provided between the fixed shell 310 and the rotors 200.

[0029] In this embodiment, the wind force and direction experienced by the UAV body 100 can be detected in real time by the detection component 320. When the wind force is detected to be large or the wind direction changes suddenly, the adjustment component 330 can work in conjunction with the detection results to automatically adjust the angle of the rotor 200 so that the rotor 200 deflects to a windward angle more suitable for the current wind direction, thereby forming a compensating aerodynamic force, improving the flight stability of the UAV in crosswind and gust environments, and reducing the risk of flight path deviation and attitude disturbance.

[0030] It should be noted that the existing unmanned aerial vehicle (UAV) 100 includes basic components such as the wing frame 110, rotor 200, power battery, flight control module, GPS positioning module, and spraying device. The detection component 320 only senses and samples the external wind speed and direction and does not interfere with the internal data processing of the aircraft. After receiving the control command, the adjustment component 330 only makes minor adjustments to the installation angle of the rotor 200. The structural scope is limited to the connection end of the rotor 200 and does not involve the power transmission system or other flight control components. While achieving the function of resisting wind interference, it will not affect the normal flight, navigation and spraying functions of the UAV 100, ensuring the safety and stability of the entire aircraft operation.

[0031] like Figure 2 , Figure 3 and Figure 4As shown, the detection assembly 320 includes a rotating seat 321 rotatably mounted on the top of the fixed housing 310, a wind cup 322 fixedly mounted on the top of the rotating seat 321, and a plurality of air guide plates 323 fixedly mounted on the outer side of the wind cup 322.

[0032] In this embodiment, the rotating seat 321 enables the wind cup 322 to rotate freely with the wind, achieving automatic alignment of the wind direction and real-time sensing of the wind speed. Multiple wind guide plates 323 are fixedly installed on the outside of the wind cup 322 and are symmetrically distributed around it, which helps to drive the wind cup 322 to rotate synchronously when sensing the wind force, thereby improving the accuracy of wind direction detection and start-up performance.

[0033] Inside the wind cup 322, a guide ring 324 is rotated and installed. Inside the guide ring 324, a guide vane 325 is fixedly installed. Inside the wind cup 322, a rotation sensor 326 is fixedly installed. The output end of the rotation sensor 326 is fixedly connected to the guide vane 325.

[0034] In this embodiment, the rotation sensor 326 is fixedly installed inside the wind cup 322, and its output end is fixedly connected to the guide vane 325. It can convert the rotational speed of the guide vane 325 into an electrical signal output in real time, thereby achieving accurate acquisition and real-time feedback of wind speed information. Because the guide vane 325 is located inside the enclosed wind cup 322, external wind turbulence or foreign object interference is avoided, ensuring the continuity and accuracy of the detection data.

[0035] Multiple air guide plates 323 are arranged in a ring around one side of the air cup 322, and the fixing shell 310 is spherical.

[0036] In this embodiment, the surrounding wind deflector 323 can better sense the airflow, thereby improving the accuracy of wind direction perception. The spherical shape of the fixed shell 310 not only has a good aerodynamic shape, but also can effectively reduce wind resistance and turbulence interference during flight. The spherical structure has consistent mechanical properties when exposed to wind at different angles, which improves the structural stability and impact resistance of the detection component 320 in high-speed flight, turning or wind disturbance environments.

[0037] The bottom of the drone body 100 is fixedly mounted with a support leg 130, and a camera 140 is fixedly mounted on one side of the support leg 130.

[0038] In this embodiment, by setting a support leg 130 at the bottom of the unmanned aerial vehicle body 100, a stable support foundation can be provided for the whole machine during takeoff and landing. A camera 140 is fixedly installed on one side of the support leg 130, so that the camera 140 has a good top-down view during operation and can take real-time pictures and collect images of ground vegetation, water channels, spraying effects, etc.

[0039] like Figure 2 , Figure 3and Figure 4 As shown, the adjustment assembly 330 includes a mounting plate 331 fixedly installed between the wing frame 110 and the fixed housing 310. A motor 332 is fixedly installed on one side of the mounting plate 331. An adjustment housing 333 is rotatably installed inside the fixed housing 310. The output end of the motor 332 is fixedly connected to the outside of the adjustment housing 333.

[0040] In this embodiment, the motor 332 drives the adjustment shell 333 to rotate inside the fixed shell 310, thereby indirectly adjusting the angle of the rotor 200 connected to it. The rotor 200 can be adjusted in conjunction with the wind speed and wind direction detection results to deflect the rotor 200 to the optimal windward angle to adapt to the current wind direction.

[0041] The rotor 200 is located at the bottom of the regulating housing 333, and the rotor 200 is fixedly connected to the bottom of the regulating housing 333.

[0042] In this embodiment, by setting the rotor 200 at the bottom of the adjustment shell 333 and fixing it to the bottom of the adjustment shell 333, the rotor 200 can achieve overall angle deflection as the adjustment shell 333 rotates. The layout structure is compact and the transmission path is short, which is conducive to improving the response speed and control accuracy of angle adjustment, and ensures that the rotor 200 can make rapid adjustments according to changes in wind speed and wind direction during flight.

[0043] The two sides of the rotor 200 are fixedly connected to the inside of the fixed shell 310 by telescopic belts 334, which are set in an arc shape.

[0044] In this embodiment, the telescopic belt 334 adopts an arc-shaped structure design, which can maintain compliant extension and rebound during the angle change of the rotor 200. It not only effectively buffers the inertial impact during the operation of the rotating mechanism, but also provides auxiliary reset or stable support after the rotor 200 is adjusted to the correct position. This structure enhances the control precision and anti-vibration capability of the adjustment structure without increasing the weight and volume of the rotor 200.

[0045] Working principle: During use, when the plant protection irrigation drone takes off, the wind-resistant mechanism 300 starts to operate synchronously. The wind cup 322 in the detection component 320 rotates freely through the rotating seat 321 under the action of wind force, automatically aligning with the current wind direction. The guide vane 325 inside the wind cup 322 rotates synchronously with the guide ring 324. Its rotation speed is collected by the rotation sensor 326 and outputs a wind speed signal for the flight control module to judge and analyze. When the wind speed is high or the wind direction changes suddenly, the flight control module sends a control command to the adjustment component 330. The motor 332 installed on the mounting plate 331 starts, driving the fixedly connected adjustment shell 333 to deflect. Due to the rotor 2 The rotor 200 is fixedly installed at the bottom of the adjustment shell 333. The rotor 200 can be adjusted as the adjustment shell 333 rotates, so that the rotor 200 can always maintain a better windward angle in windy environments, thereby generating stable compensating aerodynamic force and improving the flight stability of the unmanned aircraft 100. During the adjustment process, the rotor 200 is connected to the inside of the fixed shell 310 through the arc-shaped telescopic belt 334 on both sides. The telescopic belt 334 has a certain degree of extensibility and resilience, and can play a role in buffering, limiting and resetting during the adjustment action. The fixed shell 310 has a spherical design, which, together with multiple wind guide plates 323 distributed around the outside, can effectively reduce wind resistance and stabilize airflow direction.

[0046] It should be noted that the drone body, rotation sensor, and motor mentioned above are all components with relatively mature existing technologies. The specific models can be selected according to actual needs. At the same time, the drone body, rotation sensor, and motor can be powered by the built-in power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
