[0002] Agricultural drones are an important part of modern agricultural technology. They use advanced drone platforms equipped with various sensors and monitoring equipment to conduct real-time monitoring and data collection of crops, so drones are needed for crop monitoring. Existing drones usually use crop monitoring methods such as ground sensors when in use, which may limit the flight and monitoring range of drones, resulting in low efficiency, high cost and limited monitoring range.

[0003] In order to overcome the above-mentioned defects, the prior art (application number: 201921225170.4, Chinese patent with application date of July 31, 2019) discloses a drone device for monitoring the growth of crops. The drone device, by setting two cameras, performs image processing and three-dimensional reconstruction on images obtained at different angles to obtain images with depth information, and can more accurately analyze the actual growth status of crops in the farmland, which is convenient for unified planning and management of the farmland. By setting small motors, rotating drums, fixed rings and other structures, the camera is driven to rotate, the shooting area is expanded, the monitoring range is expanded, and it is beneficial to monitor the growth of crops.

[0004] Although the existing technology can solve the problem of photographing farmland to obtain information, the two cameras installed can only obtain images of crops in the farmland, and cannot provide accurate feedback for the flight control system of the drone for real-time monitoring, reduce the drone's quick descent, and the shock-absorbing components cannot be adjusted, which cannot effectively ensure that the drone can stably contact the ground when landing, and the two cameras cannot be disassembled and quickly installed; therefore, we proposed a quick-descent crop monitoring drone that can solve the above problems well.

During the movement of the clamping plate 18, the connected guide rod 19 is driven to retract and retract in the mounting seat 15, and at the same time, the connected spring 20 is stretched or squeezed to increase the stability and guidance of the movement of the clamping plate 18, so that the two clamping plates 18 move away from each other and separate from the monitoring device body 21, thereby disassembling the monitoring device body 21, or the two clamping plates 18 move close to each other and fit on the outer wall of the monitoring device body 21, then manually insert the bolt 17 through the handle into the corresponding threaded hole in the mounting seat 15, so that the screw 16 is fixed in the mounting seat 15, thereby fixing and installing monitoring device bodies 21 of different sizes and specifications, realizing the disassembly and quick installation of the monitoring device body 21, while ensuring the stability of the clamping and the adaptability to equipment of different specifications, providing strong support for the monitoring mission of the drone.
