Unmanned aerial vehicle

The invention relates to an unmanned aerial vehicle which comprises a vehicle body, a rack, a radar flow measurement probe, a radar water level indicator and a water sampling module. The radar flow measurement probe and the radar water level indicator are installed below the vehicle body, and the water sampling module is installed on one side of the vehicle body. A battery module and a control module are arranged in the vehicle body. The radar flow measurement probe, the radar water level indicator and the water sampling module are connected with the control module. The radar flow measurementprobe, the radar water level indicator, the water sampling module and the control module are connected with the battery module. The unmanned aerial vehicle integrates flow measurement and water sampling and can substitute workers to conduct flow measurement and sampling work under various extreme and complex conditions, so that labor cost is saved, and various safety accidents can be avoided. 本发明涉及种无人机，包括机体、机架、安装于机体下方的雷达测
