Description

Technical Field

[0001] The utility model relates to the technical field of monitoring unmanned aerial vehicles (UAVs), in particular to a remote sensing monitoring UAV based on farmland disaster conditions. Background Art

[0002] Agricultural disasters, such as droughts, floods, hail, typhoons, and pests and diseases, pose a serious threat to agricultural production. These disasters not only affect crop yield and quality, but can also cause significant losses to farmers' economic income. Therefore, timely and accurate monitoring of farmland disasters is of great significance for reducing disaster losses and ensuring agricultural production. Traditional methods for monitoring farmland disasters mainly include manual inspections and remote sensing technology. However, these methods have problems such as time-consuming, labor-intensive, and untimely. With the widespread popularization of smart agriculture and forestry and the rapid development of drone technology, its application in the agricultural field is becoming increasingly extensive. Drones are fast, flexible, and efficient, and can be equipped with a variety of sensors for high-precision and high-resolution remote sensing monitoring, providing a new solution for farmland disaster monitoring. Drone technology based on remote sensing monitoring of farmland disasters has broad development prospects. With the continuous advancement of technology and the continuous expansion of application scenarios, drones will play an increasingly important role in agricultural disaster monitoring, providing more accurate and efficient services for agricultural production.

[0004] The damping rods are respectively fixedly mounted on the bottom of the inner side surface of the fixed box, and a bottom plate is fixedly mounted on the top of the damping rod; a top plate is arranged on the top of the fixed box; and a rubber ball is respectively fixedly mounted on one side of the movable plate, the top of the bottom plate and the bottom of the top plate. The utility model provides a farmland pest and disease monitoring drone, which cooperates with each other through structures such as a fixed box, a top plate, a second threaded rod, a movable plate, a damping rod, a spring and a rubber ball. When in use, it can buffer vibrations generated in multiple directions, thereby protecting the monitoring device.

[0005] However, the monitoring effect of this device is not good. The farmland area is large, and the drone may encounter airflow disturbances or mosquito interference during flight, resulting in unclear shooting images, which further reduces the monitoring effect of the drone. Therefore, a remote sensing detection drone for farmland disasters is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1 In this embodiment, a remote sensing monitoring drone based on farmland disaster conditions includes a fuselage 1, a battery pack 2 is clamped on the top of the fuselage 1, two wings 3 are fixed on the left and right sides of the fuselage 1, and the provision of four wings 3 can effectively improve the stability of the drone during flight. An electric rotating platform 4 is fixed at the bottom of the fuselage 1, and a monitoring mechanism 5 for monitoring farmland disaster conditions is provided at the bottom of the electric rotating platform 4.

[0025] In addition, the fuselage 1 is composed of a casing 101 and a processor 102. The casing 101 is snap-connected to the battery pack 2. The processor 102 is fixed on the inside of the casing 101. The processor 102 is configured to control the flight attitude in real time and remotely transmit the image data to the monitoring center, so that the monitoring center can analyze the farmland disaster in a timely manner.

[0026] It can be known that each wing 3 includes a connecting rod 301 fixed to the side wall of the fuselage 1, and a base 302 is fixed to the end of the connecting rod 301 away from the fuselage 1, and a brushless motor 303 is fixed on the inner side of the base 302. The output shaft of the brushless motor 303 passes through the outside of the base 302, and a propeller 304 is fixed on the output shaft of the brushless motor 303 and located on the outside of the base 302. The brushless motor 303 has the advantages of low noise, high torque, and high speed, and can provide a strong guarantee for the flight of the drone.

[0027] In this embodiment, the four wings 3 can improve the flight lift and flight speed, further improving the monitoring efficiency. At the same time, the quad-rotor has better flight stability than the twin-rotor UAV, which can effectively increase the monitoring effect.

[0028] Please refer again Figure 1 and Figures 2 to 3 In order to improve the monitoring effect, the monitoring mechanism 5 in this embodiment includes a shell 501 fixed to the bottom of the electric rotating table 4, the inner cavity of the shell 501 is provided with a power component 502, and the inner side of the power component 502 is provided with a video recording component 503.

[0029] It can be known that the outer shell 501 is in the shape of a double-square character. The double-square character design can wrap the video component 503 inside, achieving the purpose of protecting the video component 503. Two connecting holes are provided on the inner side wall of the outer shell 501. Each driven rod 5024 passes through the connecting hole to the outside of the inner side wall of the outer shell 501 and is fixed to the video component 503. Through the two driven rods 5024, power can be effectively transmitted, further prompting the video component 503 to rotate back and forth.

[0030] In addition, the power component 502 includes a stepper motor 5021 fixed to the right side wall of the inner cavity of the outer shell 501. The output shaft of the stepper motor 5021 is fixed with a driving rod 5022. The left and right side walls of the inner cavity of the outer shell 501 are both rotationally connected with a transmission rod 5023 through bearings. The left and right side walls of the inner cavity of the outer shell 501 and below the transmission rod 5023 are both rotationally connected with a driven rod 5024 through bearings. Two driving gears 5025 are fixed to the outer surface of the driving rod 5022. A transmission gear 5026 is fixed to the outer surface of each transmission rod 5023. A driven gear 5027 is fixed to the outer surface of each driven rod 5024. Using gears to transmit power can ensure the accuracy of power transmission, improve the control effect on the video component 503, and further improve the monitoring effect. At the same time, compared with belt drive, gear drive is more reliable and very durable.

[0031] It should be further noted that two relief grooves are provided on the top wall of the inner cavity of the outer shell 501. The two relief grooves are respectively adapted to the two driving gears 5025. The two relief grooves can ensure the smooth rotation of the two driving gears 5025, further improving the running stability of the two driving gears 5025. The upper and lower sides of each transmission gear 5026 are respectively meshed with the driving gear 5025 and the driven gear 5027. By setting the transmission gear 5026, the power of the driving gear 5025 can be smoothly transmitted to the driven gear 5027, thereby realizing the angle adjustment of the video component 503.

[0032] In addition, the video component 503 includes a sphere 5031 fixed to the two driven rods 5024. A partition 5033 is fixed inside the sphere 5031. A servo motor 5034 and a camera 5032 are respectively fixed to the left and right sides of the partition 5033. The output shaft of the servo motor 5034 is fixed with a rotating shaft 5035. A flywheel 5036 is fixed to the outer surface of the rotating shaft 5035. When the flywheel 5036 rotates, a large moment of inertia will be generated, which can ensure the stability of the rotation of the flywheel 5036, thereby ensuring the stability of angular momentum, further improving the stability of the camera 5032, and improving the shooting quality. The end of the rotating shaft 5035 far from the servo motor 5034 is rotationally connected to the inner side wall of the sphere 5031 through a bearing. A communication hole is provided on the right side of the sphere 5031. The camera 5032 passes through the communication hole to the outside of the sphere 5031.

[0033] In this embodiment, the cooperation of the electric rotating platform 4 and the stepper motor 5021 can effectively improve the shooting range of the camera 5032, further improve the monitoring range of the drone, and at the same time, cooperate with the continuous rotation of the flywheel 5036 to keep the camera 5032 running stably.

[0034] It can be understood that, through the coordination of the four wings 3 and the flywheel 5036, the flight stability of the UAV can be improved and the interference of the UAV flight on the video recording component 503 can be reduced, thereby greatly improving the quality of shooting and thus improving the monitoring effect. Then, through the coordination of the electric rotating table 4 and the power component 502, the monitoring range can be greatly improved. By improving the monitoring range and coordinating the shooting quality, the monitoring effect can be significantly increased.

[0035] The electrical components mentioned in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The power supply provided by the battery is also common knowledge in this field. Moreover, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0036] The working principle of the above embodiment is:

[0037] First, install the charged battery pack 2 on the housing 101. The operator can remotely operate the drone indoors or drive the drone with the specified video installed. During the operation, the processor 102 will control the four brushless motors 303 in real time to adjust the flight attitude and turn the drone. At the same time, during the flight of the drone, the stepper motor 5021 can be remotely operated to cause the two driving gears 5025 to transmit power to the two driven gears 5027 through the two transmission gears 5026, further causing the video component 503 to rotate as a whole, and at the same time cooperate with the electric rotating platform 4. Rotation can achieve blind-angle monitoring of the video recording component 503. At the same time, during the flight, the servo motor 5034 continuously outputs power to prompt the flywheel 5036 to rotate continuously, further ensuring that the camera 5032 remains stable during the flight of the drone, and further improving the shooting quality of the camera 5032. The device can effectively improve the stability of the drone during flight through the four-rotor design, and then through the cooperation of the electric rotating platform 4 and the stepper motor 5021, it can effectively expand the monitoring range and avoid blind spots. Finally, the flywheel 5036 further improves the shooting quality, thereby achieving high-quality monitoring effects.
