Description

Silt monitoring device

Technical Field

The utility model relates to a hydrology field, concretely relates to silt monitoring devices.

Background

The sand-containing water flow is a solid-liquid two-phase fluid consisting of silt and water, when light irradiates in the sand-containing water flow, a part of light is transmitted through the sand-containing water flow, a part of light is absorbed by the water flow and the silt, and a part of light is reflected by the water flow and the silt. In the case of low water flow sand content, most of the light is transmitted through the sand-laden water flow, and only a small portion is reflected. As the sand content of the water flow increases, the reflection of the sediment to the light is enhanced, and more light is reflected.

The received different intensities of the emitted light are converted into corresponding voltage signals with different intensities. Under a certain incident light source intensity, the corresponding relation between the sand content of different water flows and the voltage signal intensity generated by reflected light is established through a calibration test. Therefore, the sand content of the water flow can be predicted by measuring the voltage output of a given system, and the aim of measuring the sand content of the water flow is fulfilled.

When the monitoring device is placed in slow water flow or static water, the water flow in the sediment monitoring device is slow to no flow, sediment is deposited from the water flow, and the measured data are distorted.
