Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and in particular to a foldable radar wave flow velocity measuring device based on an unmanned aerial vehicle. Background Art

[0002] With population growth and economic development, the contradiction between increasing water demand and water resource shortages is becoming increasingly severe, making water scarcity a global issue. Improving water use efficiency has become a pressing need for promoting sustainable social development. Monitoring river flow and water levels is fundamental to the scheduling and full utilization of water resources. Furthermore, river flow and water level measurement and monitoring are also necessary for flood prevention and control. Flow and water level data monitored upstream are often crucial for downstream decisions regarding flood releases, scheduling, and diversion. Furthermore, research in hydrology, ecology, and environmental protection, sometimes involving studying the circulation and conversion between precipitation, surface water, and groundwater, as well as the natural recovery functions of natural rivers, requires flow rate and flow monitoring.

[0003] According to the Chinese patent application number 202020216652.X, a device for online monitoring of water flow and flow rate is disclosed, which allows maintenance personnel to repair the radar monitor while standing on the ground, making maintenance convenient and quick, saving a lot of maintenance time, speeding up maintenance efficiency, and ensuring that the radar monitor can quickly resume real-time monitoring of water flow and flow rate. However, when the device is in use, it is difficult to detect areas of the river far away from the shore, and it can only be judged based on the monitoring situation within a short distance on both sides of the river. The results obtained in this way often have large errors, and in the process of flood prevention and control, it is difficult to play its specific role because it is impossible to obtain more accurate water flow and water level data. At present, there are several flow rate measuring devices based on unmanned aerial vehicles, but they are basically based on larger unmanned aerial vehicles and adopt a bottom-mounted method. On the one hand, they cannot be adapted to small unmanned aerial vehicles. On the other hand, the installation and storage of the equipment are also very inconvenient in actual operation.
