Flow monitoring device for rivers containing sediment

Abstract

The invention discloses a flow monitoring device for rivers containing sediment, which comprises a chute and a main body, a torque motor is arranged at the top of the chute, a screw rod is installed at the output end of the torsion motor, and sliders are arranged in the chute; one side of the chute A drive motor is provided, and a winch and a drag cable are provided at the output end of the drive motor. The invention adopts the cooperation of chute, slider, screw and torque motor, and the detection main body slides within the stroke of the chute to complete the monitoring of rivers at different depths at the same point without manpower adjustment of the monitoring depth; a winch and a cable are set, and the slider exceeds The limit position of the chute, the main body breaks away from the chute and sinks into the bottom of the water, and the hydrological monitoring of the river bed and the bottom of the water follows the flow of the river, which improves the scope of application of the device, and does not require multi-equipment sampling, reducing the number of sampling devices used; slidingly installed on the mounting plate A number of sliding plates can filter and intercept sediment particles of different sizes by replacing the filter screen, and complete the flow monitoring of sediment particles in different states.

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...

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
