[0003] Currently, some agricultural drones on the market have a backpack photovoltaic panel design, which can use solar energy to provide continuous power support for the drone, thereby extending its flight time. However, these photovoltaic panels are usually fixed and exposed on the drone body, which makes the exposed photovoltaic panels susceptible to direct physical impact in weather conditions such as heavy rain and hail, resulting in damage to the photovoltaic panels.

Detailed Implementation

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Please see Figure 1-4An agricultural plant protection drone includes a drone 1, a fixed platform 2 fixedly connected to the top of the drone 1, a protective baffle 3 fixedly connected to the top of the fixed platform 2, the protective baffle 3 can provide a shielding effect for photovoltaic panels 7, the fixed platform 2 is provided with a first guide strip hole 4 and a second guide strip hole 5 respectively, and the first guide strip hole 4 and the second guide strip hole 5 are distributed at right angles, the top of the fixed platform 2 is slidably connected to a concave slide table 6, the outer surface of the concave slide table 6 is provided with photovoltaic panels 7, the two sets of photovoltaic panels 7 will not affect the flight of the drone 1 during the deployment and retraction process, the bottom of the fixed platform 2 is provided with a drive mechanism, and the top of the fixed platform 2 is provided with a deployment and retraction mechanism.

[0017] Through the above technical solution, during use, the plant protection drone 1 can move the two sets of photovoltaic panels 7 away from each other in sunny weather by using the drive mechanism in conjunction with the retraction mechanism. That is, the two sets of photovoltaic panels 7 are fully exposed to receive sunlight and convert it into electrical energy to maintain continuous flight. In case of heavy rain or hail, the two sets of photovoltaic panels 7 can be stored in the protective baffle 3 to achieve an effective protection effect.

[0018] Specifically, the drive mechanism includes an inner drive base 8 fixedly installed at the bottom of the fixed platform 2, and a motor 9 is fixedly installed at one end of the inner drive base 8.

[0019] With the above technical solution, when the motor 9 starts, it drives the lead screw 10 to rotate. Since the shift plate 11 is threadedly connected to the lead screw 10 and under the limiting action of the guide groove 12, the shift plate 11 will move linearly along the axis of the lead screw 10. This transmission method can convert rotational motion into linear motion, accurately control the displacement of the shift plate 11, and provide precise drive for the subsequent retraction mechanism.

[0020] Specifically, the output end of the motor 9 is fixedly connected to a lead screw 10, the outer surface of the lead screw 10 is threadedly connected to a shift plate 11, the outer surface of the inner drive seat 8 is provided with a guide groove 12, and the inner wall of the guide groove 12 is slidably connected to the outer surface of the shift plate 11.

[0021] Through the above technical solution, the outer surface of the lead screw 10 is provided with threads of the same length and opposite direction from the middle to both ends. This is to enable the lead screw 10 to drive the two sets of shift plates 11 to move synchronously during its rotation.

[0022] Specifically, the retraction mechanism includes a connecting rod 13 that is slidably connected in the first guide bar hole 4, and the bottom of the connecting rod 13 is fixedly connected to the top of the shift plate 11, and the top of the connecting rod 13 is fixedly connected to the drive platform 14.

[0023] Through the above technical solution, the linear motion of the shift plate 11 can drive the connecting rod 13 to slide in the first guide bar hole 4, thereby causing the drive platform 14 to move. The first guide bar hole 4 plays a guiding role in the movement of the connecting rod 13, ensuring the accuracy of its movement trajectory, so that the drive platform 14 can move in the predetermined direction.

[0024] Specifically, a first arm shaft 15 is fixedly inserted through the inner side of the drive platform 14, and a swing arm 16 is rotatably connected to the outer surface of the first arm shaft 15.

[0025] Through the above technical solution, the displacement of the drive platform 14 will drive the first arm shaft 15 to move. Since the swing arm 16 is rotatably connected to the first arm shaft 15, the swing arm 16 will swing accordingly. This rotatable connection method allows the swing arm 16 to flexibly change its angle, providing an objective basis for subsequently driving the concave slide table 6 to move.

[0026] Specifically, the concave slide table 6 is provided with a second arm shaft 17 at both ends. The outer surfaces of the two sets of second arm shafts 17 are rotatably connected to the end of the swing arm 16 away from the first arm shaft 15, and the outer surfaces of the second arm shafts 17 are slidably connected to the inner wall of the second guide bar hole 5.

[0027] Through the above technical solution, the swing of the swing arm 16 will drive the second arm shaft 17 to slide in the second guide strip hole 5, thereby pushing the concave slide table 6 to slide on the top of the fixed platform 2, realizing the storage and unfolding action of the photovoltaic panel 7. The second guide strip hole 5 plays a guiding and limiting role in the movement of the second arm shaft 17, ensuring the stability and accuracy of the movement of the concave slide table 6.

[0028] Working principle: Under clear weather conditions, before the drone 1 prepares to carry out plant protection operations, the photovoltaic panel 7 is in the unfolded state. At this time, the photovoltaic panel 7 is fully exposed to sunlight, using the photovoltaic effect to convert solar energy into electrical energy to charge the drone 1's battery system, thereby extending the drone 1's flight time. After the drone 1 takes off, it flies over the farmland according to the preset route. During the flight, the photovoltaic panel 7 continuously absorbs solar energy and converts it into electrical energy. When encountering severe weather such as sudden rain or hail, the motor 9 is immediately started, and its output end drives the lead screw 10 to rotate. Since the displacement plate 11 is threadedly connected to the lead screw 10, and the outer surface of the lead screw 10 has threads of the same length but opposite directions from the middle to both ends, the relative positioning of the guide groove 12 on the inner drive seat 8 is limited. Under the action, the two sets of shift plates 11 will move synchronously in opposite directions along the lead screw 10. That is, as the two sets of shift plates 11 approach each other, they will drive the corresponding connecting rods 13 to move synchronously. During this period, the two sets of connecting rods 13 will slide closer along the first guide bar hole 4, thereby causing the two sets of drive platforms 14 to approach synchronously. During the movement, the drive platform 14 will drive the swing arm 16 to swing through the first arm shaft 15. The swing of the swing arm 16 will further drive the second arm shaft 17, which is rotatably connected to it, to slide in the second guide bar hole 5. During this period, the swing arm 16 is equivalent to pulling the second arm shaft 17 to slide in the second guide bar hole 5. Finally, as the two sets of concave slide tables 6 approach each other, they drive the two sets of photovoltaic panels 7 to gradually move downwards towards the protective baffle 3, thereby achieving the storage effect of the photovoltaic panels 7.

[0029] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
