AI Technical Summary

Technical Problem

The prior art is difficult to efficiently detect the sand content in the flowing water, resulting in low detection efficiency and limitations.

Method used

A sand content detection device for water conservancy engineering is designed, including a base, a support frame, a liquid inlet pipe, a connecting pipe and a particle detection component. By adjusting the angle of the particle detection assembly and pushing the first connecting pipe to move into the second liquid inlet pipe in the first liquid inlet pipe, the connection between the two is realized. After the detected water flows into the second liquid inlet pipe through the pipe, the particle detection assembly emits laser light and analyzes the characteristics of the laser after interacting with water and sand particles to infer the concentration and distribution of sand particles in the water.

Benefits of technology

Efficient detection of sand content in flowing water bodies is achieved, the accuracy and reliability of detection are improved, and the problems of low detection efficiency and limitations in the prior art are overcome.
