Description

Technical Field

[0001] This utility model specifically relates to the technical field of sediment collection equipment, and more specifically to a sediment collection device for river channels. Background Technology

[0002] In fields such as water conservancy engineering construction, river ecological environment monitoring, and hydrological research, river sediment collection is a crucial step in obtaining basic data. Accurately collecting sediment samples from different depths and areas plays a decisive role in analyzing river sedimentation, studying sediment transport patterns, and assessing the impact of water conservancy facilities on the sediment environment.

[0003] In shallow river sections, manual sampling using handheld tools is commonly employed. This method is limited by manpower, only able to collect surface or shallow sediment, failing to obtain samples from deeper or specific layers. It is particularly difficult to access areas with deeper water and stronger currents. Furthermore, manual sampling involves significant variations in sampling pressure and angle, resulting in poor sample representativeness and large fluctuations in results from different personnel and sampling sessions, failing to accurately reflect the true distribution of sediment in the riverbed. Simultaneously, manual sampling is extremely inefficient; for long river sections with multiple sampling points, it consumes substantial manpower and time, making it difficult to complete systematic data collection in a short period.

[0004] River currents are complex, with variations in flow velocity, eddies, and undercurrents. Simple equipment lacks effective fixation and is easily shaken and shifted by the impact of the water flow, leading to sampling position deviations or even equipment loss. For example, during the flood season when the water flow is rapid, it is difficult to lower the sampling tube vertically to the intended position, and the collected sediment may contain materials from different areas and depths, disrupting the stratification characteristics of the sample.

[0005] Most simple equipment collects mud and sand mixed with a large amount of river water, lacking efficient screening and separation design. Subsequent manual dehydration and screening are required, increasing the workload and easily introducing impurities and changing the original state of the sample during the processing, affecting the analysis results.
