Description

Technical Field

[0001] The utility model relates to the technical field of measuring instrument installation, and more specifically, to an installation structure of a water flow velocity measuring instrument based on an unmanned aerial vehicle. Background Art

[0002] Water flow rate detection is widely used in many fields such as water conservancy projects, environmental monitoring, industrial production, municipal water supply, etc. With the growth of the global population base and the scarcity of water resources, water resources management has received increasing attention and the development of intelligent measurement and control technology. The water flow rate detection market has shown a steady upward trend and will maintain its current growth status for a long time. In the process of testing water flow rate, it is usually necessary to carry a measuring instrument with a drone for testing, and then collect data through the LoRa device and transmit it to the host computer to achieve measurement. However, when installing traditional measuring instruments, they are mostly fixed by bolts, which makes it more troublesome to install and disassemble them. In addition, the measuring instruments are mostly installed directly at the lower end of the drone. The upper end of the river is more humid and wet. Since the drone needs to hover over the river for a period of time during measurement, the measuring instrument is prone to damage over time. Utility Model Content
