Description

Technical Field

[0001] The invention relates to the technical field of water conservancy detection equipment, and more specifically to a river water and sand detection device. Background Art

[0002] The regulation of river channels, the construction of embankments, and the management of waterways all require the study of the movement of river sediment. Irrigation and drinking water projects need to consider the amount of sediment entering the channel and the hydraulic conditions for the channel to not be eroded and silted. Soil and water conservation projects need to study the sediment production process in the basin. Therefore, the measurement of sediment is of great significance in many aspects of human economic activities. Sediment is deposited at the bottom of the river. Sediment is a mixture of countless particles of different sizes, shapes, and minerals. Sediment transport is an important hydrological phenomenon in rivers and has a significant impact on the changes of rivers. When heavy rain falls on the surface of the basin, in the process of runoff and confluence, the rock and soil of the slopes and gullies are eroded and transported to the river by water flow to form river sediment. The study of river sediment is of great significance to the management of rivers. Therefore, in order to monitor the sediment content in the river channel and effectively prevent and control the phenomenon of soil erosion, it is usually necessary to sample the river channel. Since sediment is easy to deposit, the sediment content at different water depths is different. Sampling is required at different water depths to reflect the sediment content of the water flow in the river channel as a whole. However, in the prior art, when using a sampling device to detect the sediment content of river water, the natural sedimentation of sediment is used to collect data on the sediment content of river water within a period of time. This method not only reduces the sampling rate, but also cannot prevent some sediment from being lost with the river water, thus resulting in inaccurate collected data. In addition, the flow rate of river water is an important factor affecting the sediment content of river water. Therefore, when collecting, it is necessary to always keep the overall flow rate inside the sampling tube consistent with the water flow rate at the water inlet pipe and the natural flow rate. However, traditional sampling equipment cannot monitor and adjust the overall flow rate inside the sampling tube, the water flow rate at the water inlet pipe, and the natural flow rate of the river water at the same depth in real time, reducing the accuracy of the collected data. River management sometimes requires water sampling, and it is also necessary to detect information such as deposited sediment.

[0003] Therefore, in response to the current problems, how to provide a river water and sand detection device that can ensure that while sampling over a larger range, sediment and water at different heights can be sampled simultaneously, and at the same time, it can ensure that there is no mutual interference during the sampling process and ensure the accuracy and representativeness of the samples, is a problem that technical personnel in this field urgently need to solve.
