Description

Technical Field

[0001] This utility model relates to the field of measurement technology, specifically to a device for fixing a sensor when measuring the scouring force of a river channel. Background Technology

[0002] Studying river scour forces has significant scientific, engineering, and environmental implications, crucial for understanding river dynamics, riverbed evolution, and the design and maintenance of related water conservancy projects. It not only contributes to a deeper understanding of the interaction between water flow and the riverbed but also provides scientific evidence for river management, water conservancy project design, ecological restoration, and agricultural conservation. By understanding the patterns of scour forces, we can effectively manage rivers, reduce soil erosion, improve the ecological environment, lower disaster risks, and enhance disaster prevention and mitigation capabilities, thereby ensuring sustainable social, economic, and ecological development. Measuring river scour forces using pressure sensors is a direct and accurate method. Pressure sensors can be installed on the riverbed surface or at other locations to monitor the scour force exerted by water flow on the riverbed in real time, thus aiding in the study of river erosion processes. This parameter is significant in agriculture, soil engineering, and environmental science, influencing irrigation management, soil moisture retention, pollutant migration, and many other aspects.

[0003] While pressure sensors offer significant advantages in determining riverbed scour forces, they also have some limitations. First, accurate measurement of riverbed scour forces is often influenced by various factors, such as water velocity, flow rate, depth, and particle size in the riverbed. This makes it difficult to accurately obtain the scour force in practical applications, thus affecting its calculation. Second, the stability of the pressure sensor is crucial during experiments, as its stability directly impacts the measurement results. Utility Model Content
