Description

Technical Field

[0001] The utility model relates to the technical field of flow measuring devices, in particular to a flow measuring device for hydrological testing that is easy to carry. Background Art

[0002] The flow measuring device for hydrological testing is a system for monitoring water flow velocity, water level and other hydrological parameters. It usually includes sensors, data acquisition equipment and wireless communication equipment. Its core function is to monitor the changes in water flow in real time and provide accurate hydrological data. Traditional flow measuring devices generally install the flow measuring probe at one end of the telescopic rod. The user adjusts the measuring depth of the measuring probe by extending the telescopic rod. However, the length adjustment range of the telescopic rod is fixed, which leads to certain limitations in the measuring range of the measuring device and reduces the flow measurement efficiency of the flow measuring device.

[0003] In order to address the above problems, a Chinese patent with the existing announcement number CN220671468U proposes a flow measuring device for hydrological testing. The device adjusts the relative distance between the connecting frame and the lifting plate by rotating the threaded column, and indirectly adjusts the initial position of the measuring probe. The servo motor drives the screw rod to rotate so that the lifting plate slides along the screw rod, and the height of the measuring mechanism is adjusted, thereby improving the flow measurement efficiency of the flow measuring device.

[0004] However, although the above-mentioned flow measuring device for hydrological testing can adjust the coverage of the measuring mechanism by rotating the screw, the overall volume of the flow measuring device for hydrological testing is relatively large, and the connecting structure is not easy to disassemble, which causes the problem of inconvenience in carrying. Therefore, the utility model provides a flow measuring device for hydrological testing that is easy to carry to meet the needs. Utility Model Content
