Abstract

The invention provides a detecting device and a detecting method for the particle diameter of river sediment and relates to the technical field of water quality monitoring. The detecting device is arranged in a river to be detected and comprises a coherent laser optical fiber component, an image sensor, a connector and a computer, wherein the coherent laser optical fiber component and the image sensor are respectively arranged at the two ends of the connector in a sealing manner; a detecting channel for passage of the river is arranged on the connector between the coherent laser optical fibercomponent and the image sensor; the output end of the image sensor is connected with the input end of the computer. The detecting device and the detecting method provided by the invention have the advantages that in-situ detection can be carried out in real time and on site, the equipment is simple, the operation is convenient, and the resolution can reach 0.6mu m.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring, in particular to a device and method for detecting the particle size of river sediment particles. Background technique [0002] Sediment particle analysis is the basic work in sediment research, which mainly provides basic information for the research of river evolution, water ecological environment and geological geomorphology. There are many analysis methods, including the sieving method with simple equipment and intuitive results and the laser method with fast testing speed. But both have the following disadvantages: [0003] 1. Sieving method: The size of the sieve holes will change with the time of use, resulting in a decrease in the accuracy of the analysis results; the test takes a long time and cannot be repeated. [0004] 2. Laser method: It is very sensitive to the external environment and has high requirements for the operator. Contents of the invention [0005] T...
