Description

Technical Field

[0001] The utility model specifically relates to a sediment runoff monitoring system and belongs to the technical field of sediment monitoring. Background Art

[0002] Soil erosion refers to the phenomenon that due to natural or human factors, rainwater cannot be absorbed locally, flows downstream and washes the soil, causing the loss of both water and soil. Excessive soil erosion will have a serious impact on the environment, especially in some mountainous areas, rivers, reservoirs, lakes and other areas. Special attention should be paid to areas with serious soil erosion. The sediment runoff detection equipment can conduct quantitative and qualitative analysis of the sediment carried in the surface runoff, accurately understand the situation of soil erosion and evaluate the effectiveness of soil and water conservation measures, and provide a scientific basis for water resources management and ecological environment protection. It is often used in conjunction with surface runoff cells, and the runoff cells are used as sampling points for regional monitoring and evaluation.

[0003] Existing sediment runoff monitoring systems mostly use collection buckets to collect water flow and then perform sediment detection after collection. However, since sediment tends to sink easily in water, sediment is often deposited before detection begins during the collection process, making it difficult to monitor. A large amount of sediment settles under the water in the collection bucket, resulting in inaccurate monitoring. The traditional solution is to stir the water to suspend the sediment again, but during stirring, the sediment will aggregate again due to centrifugal action, which will also affect the accuracy of the monitoring data.
