Description

Technical Field

[0001] The utility model relates to the technical field of river water level measurement, in particular to a river water level measuring device. Background Art

[0002] River monitoring is a comprehensive process that aims to understand the various conditions of the river, including water quality, water volume, flow rate, water level morphology and surrounding environment, in order to support the protection, management and sustainable development of the river. Water level measuring devices are needed when conducting water level detection.

[0003] In the prior art, announcement number CN220120204U discloses a river water level measuring device, wherein the regulating device includes a through groove, a threaded rod is rotatably connected between the inner walls at both ends of the through groove, a fixed plate is fixedly installed on the side of the extension rod, a motor is fixedly installed on the surface of the fixed plate, a hollow groove is opened on the outer wall surface of both ends of the extension rod, a sliding rod is fixedly installed between the inner walls at both ends of the hollow groove, the surface of the threaded rod is threadedly connected to a moving block, a U-shaped plate is fixedly installed on the bottom surface of the moving block, and an ultrasonic water level meter is fixedly installed on the bottom surface of the U-shaped plate. The present utility model solves the problem that the existing river water level measuring device usually inserts a measuring rod into the riverbed and then observes the position where the water surface submerges the measuring rod to determine the water level of the river. However, this measurement method will result in its measuring point being fixed, making it difficult to perform multi-position measurement operations, and further making its river water level measurement data incomplete.

[0004] However, the device still has some problems. By setting an adjustment device, when the measurement position needs to be adjusted, the ultrasonic water level meter is moved in conjunction with the adjustment device, so that positions at different distances of the river can be measured, which further improves the accuracy of the measurement data and reduces the errors generated during measurement. In actual use, when measuring the water level of the river, in order to ensure the accuracy of the measurement, it is necessary to always keep the device perpendicular to the river. As the river is constantly washed by the river water and the roots of trees beside the river invade, the river may become uneven. This may cause the measuring device to become skewed and unable to be perpendicular to the river, resulting in inaccurate measurement data. Therefore, we disclose a river water level measuring device to meet people's needs. Utility Model Content
