Problems solved by technology

Especially when surface runoff has just occurred, the surface runoff flow rate is very small. In order to obtain the runoff sediment content at this time, it is necessary to use a sampling container to collect a certain volume of runoff muddy water to meet the solution volume requirements that can be measured by gamma rays; but The sediment content measured at this time may be the average sediment content in a long period of time, which cannot meet the requirements of some scientific research and testing, and cannot obtain the change of sediment content in a short period of time.

Abstract

The present invention discloses one apparatus for collecting surface runoff flow and measuring the sediment content in runoff flow. The technological scheme is that the apparatus consists of sampling chamber, stirrer, drainage valve, valve controller, upper liquid level probe and lower liquid level probe on the side wall of sampling chamber, controller, gamma ray output device and gamma ray set separately on the two sides of the sampling chamber, and automatic calibrator. The apparatus has simple structure, simple installation, reliable work performance, long service life and high automation and may be used in the fast, real-time and accurate in-situ measurement of the sediment content in runoff flow.

Description

technical field [0001] The present invention relates to an automatic muddy water measuring device for continuously collecting surface runoff muddy water to measure the runoff sediment content and its change with time when conducting research on soil erosion, soil and water conservation, ecological environment, water conservancy engineering, natural geography and the like. It belongs to the technical field of soil erosion experiment detection and river sediment change observation, namely G01N33 / 18. Background technique [0002] Runoff sediment content is an important content of soil erosion, soil and water conservation, hydrological research, and river sediment detection. On-site rapid, real-time and accurate measurement of sediment concentration is an urgent problem to be solved. The traditional method of sediment concentration measurement is to manually collect mud and water samples, then dry and weigh them. This method cannot realize the continuous change process of real-...
