Description

Technical Field

[0001] The utility model relates to the technical field of sand content detection, and more specifically, to a sand content detection device. Background Art

[0002] Sediment content detection is an important task in water conservancy projects to monitor the concentration of suspended particles in water bodies. Monitoring the sediment content in water bodies has multiple functions. First, it can help study the characteristics of water bodies, understand the concentration and composition of suspended particles in water bodies, and thus conduct in-depth research on the nature and evolution of water bodies. Secondly, sediment content monitoring is of great significance for flood prediction and early warning. Water bodies with high sediment content may lead to river siltation and reservoir blockage, which in turn may cause floods. In addition, sediment content detection can also evaluate the degree of water pollution and provide a basis for water quality assessment and management.

[0003] There are some problems with the mud screen plates used in current sand content detection devices. During the filtration process, impurities such as mud blocks and pebbles will remain on the mud screen plates, which are difficult to clean. As a result, the water flow rate decreases after the mud screen plates are used for a long time. At the same time, the impurities on the mud screen plates will also block sand from entering the detection body, thereby affecting the accuracy of the sand meter's detection data.
