Anti-falling plant protection unmanned aerial vehicle

Abstract

The invention discloses an anti-falling plant protection unmanned aerial vehicle, and relates to the technical field of unmanned aerial vehicles, the anti-falling plant protection unmanned aerial vehicle comprises a frame, electric telescopic rods are fixedly connected to the four corners of the side surface of the frame, lifting frames are fixedly connected to the four corners of the top of the frame, and branch control valves are fixedly connected to the middle of the lifting frames. by arranging the electric telescopic rod, after the plant protection unmanned aerial vehicle takes off, the electric telescopic rod can be controlled to contract, the top rotating rod is used for driving the bottom rotating rod to rotate, the bottom support and the top support are bent, and the purpose of retracting the rising and falling support is achieved; the branch control valves are arranged, the pesticide spraying time of the pesticide spraying heads and the power assisting heads at the bottoms ofthe four lifting frames can be controlled, and when an internal controller of the electric control box detects that the unmanned aerial vehicle is out of control due to power motor faults, the singlebranch control valve is controlled to assist the lifting frames losing power, so that the purpose of preventing the unmanned aerial vehicle from falling out of control is achieved.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a fall-prevention plant protection drone. Background technique [0002] At present, with the rapid development of China's agriculture and China's science and technology, drones have been widely used in the agricultural field, such as plant protection drones, agricultural drones are unmanned aerial vehicles used in agriculture, the purpose is to help Improve crop yields and monitor crop growth. Its sensors and digital imaging capabilities can help farmers better understand their fields and help improve crop yields and farm efficiency. The main application of plant protection drones in agriculture is to spray pesticides. Compared with traditional manual spraying of pesticides, it has great advantages. It can save a lot of manpower and greatly improve the efficiency of pesticide spraying. Since the technology of plant protection drones is not yet mature, there have been many bombin...

AI Technical Summary

Problems solved by technology

Since the technology of plant protection drones is not yet mature, there have been many bombing incidents in the process of use. In serious cases, it will directly cause damage to the drone. The high cost of the drone will cause great economic losses.

[0003] At present, the software control system of the plant protection UAV is very perfect. When the UAV is in use, it is rare to lose control. However, the number of motors used on the UAV is large, and the UAV needs to be driven by the motor The propeller rotates with frequency conversion, so the probability of motor failure is very high. When the motor fails, it will cause the UAV to be seriously unbalanced, causing the UAV to fall and cause a bombing incident. It cannot be adjusted. When spraying pesticides on fruit trees, due to the different heights of the fruit trees, when the plant protection drone is adjusting the height, it is easy to make the landing bracket touch the top of the fruit tree, causing the drone to lose balance and fall.
