Description

A river cement and sand content detection device

technical field

The utility model relates to the technical field of river cement and sand content detection, in particular to a river cement and sand content detection device.

Background technique

The suspended sediment content of rivers is one of the important hydrological parameters. The monitoring of river sediment content is of great significance for the construction of water conservancy and hydropower projects, the development and utilization of water resources, the control of water and soil erosion, water intake for industry and agriculture, and hydrological forecasting. At present, the main methods of hydrologically measuring river sediment concentration include drying measurement method and indirect measurement method.

Drying assays require manual sampling and sending to a laboratory for drying and measurement of sand content. This method requires a lot of manpower, material resources and time input from sample collection to analysis, and the measurement cycle is long, the operation process is cumbersome, labor-intensive, and it is difficult to monitor the change of river sediment concentration online in real time. The indirect measurement method is a method of determining the sediment content through certain characteristics of the sediment, including modern measurement methods such as vibration method, photoelectric method, ultrasonic wave, laser method, capacitance method and gamma ray method. The indirect measurement method can make fixed-point continuous and repeated measurements on the spot without destroying the experimental environment, and is the best method for dynamic measurement of sediment concentration. However, the equipment required is very complicated and the requirements for equipment precision are also high. For example, when using the scattering or reflection method of underwater ultrasonic transmission for measurement, although the ultrasonic detection method is faster, this method requires high precision of the instrument, and the experimental process is complicated due to the strong flow of the river water. The ultrasonic loss is large and the measurement index is unstable, which makes the detection error relatively large and cannot accurately reflect the amount of river sediment in real time. However, when the optical sediment solution sediment content measurement device is used for measurement, there are shortcomings such as too many samples and cumbersome measurement process.
