Flow monitoring device for river containing silt

Abstract

The sediment-containing river flow monitoring device comprises a sliding groove and a main body, a torsion motor is arranged at the top end of the sliding groove, a screw rod is installed at the output end of the torsion motor, and sliding blocks are arranged in the sliding groove; a driving motor is arranged on one side of the sliding groove, and a winch and an inhaul cable are arranged at the output end of the driving motor. The sliding groove, the sliding block, the screw and the torsion motor are matched, the detection body slides in the stroke of the sliding groove, river monitoring at the same point position and different depths is completed, and the monitoring depth does not need to be manually adjusted; the capstan and the inhaul cable are arranged, the sliding block exceeds the limiting position of the sliding groove, the main body is separated from the sliding groove and sinks to the water bottom, hydrological monitoring of a riverbed and the water bottom is conducted along with the river flow direction, the application range of the device is widened, multi-device sampling is not needed, and the using number of sampling devices is reduced; the sliding plates are slidably mounted on the mounting plate, silt particles with different particle sizes are filtered and intercepted by replacing the filter screens, and flow monitoring of the silt particles in different states is completed.

Description

technical field [0001] The invention relates to the technical field of monitoring river sediment particles, in particular to a monitoring device for river flow containing sediment. Background technique [0002] The bottom of the river deposits sediment, which is always composed of countless particles of different sizes, shapes and minerals. Sediment transport is an important hydrological phenomenon in rivers, and it has a significant impact on the changes of rivers. When When heavy rain falls to the surface of the basin, in the process of runoff production and confluence, it erodes the rock and soil of slopes and gullies, and is transported to the river by water flow, forming river sediment. The study of river sediment is of great significance to river governance. [0003] At present, the existing river sediment particle monitoring devices are generally fixed on the river bed or the river bank, and can only complete the monitoring of the river within a certain range around t...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing river sediment particle monitoring devices are generally fixed on the river bed or the river bank, and can only complete the monitoring of the river within a certain range around the device. If it is necessary to monitor a larger river basin, it is necessary to configure several monitoring devices. Higher, and the current monitoring of sediment particles is generally a wet monitoring method and cannot distinguish sediment particles of different particle sizes, and cannot obtain diversified data of river sediment particles, which is more labor-intensive. river flow monitoring device
