An automatic monitoring device for runoff and sediment

Abstract

The invention relates to an automatic dynamic runoff sediment monitor. The automatic dynamic runoff sediment monitor comprises a protection cylinder body, a water inlet pipe and a water drainage pipe, wherein the water inlet pipe and the water drainage pipe are arranged on the protection cylinder body; a sampling weighing device, a flow converging device, a flow monitoring device and a controller are arranged in the protection cylinder body; the sampling weighing device is used for receiving and weighing part of the muddy water; the flow converging device is used for providing the stable water flow for the flow monitoring device and performing flow measurement; the controller receives data collected through the sampling weighing device and the flow monitoring device. According to the automatic dynamic runoff sediment monitor, the continuous stable sampling weighing can be performed on the runoff muddy water of a water erosion area, the flow rate of the runoff muddy water of the water erosion area can be measured simultaneously, and accordingly the way of runoff sampling weighing and flow calculation on the monitoring area in the prior art is completely changed, the manpower and material resources are greatly saved, the working efficiency and the accuracy of data collection are improved, and the great convenience is brought to the muddy water monitoring work of the water erosion runoff area.

Description

technical field [0001] The invention relates to the technical field of water and soil loss monitoring equipment, in particular to an automatic monitoring device for runoff sediment. Background technique [0002] my country is one of the countries with the most serious water and soil loss in the world. The degree of harm, development trend and scope of influence of water and soil loss need to be mastered through scientific monitoring methods. Scientific, systematic and effective monitoring and forecasting of soil and water loss can provide crucial data support for my country's soil and water conservation decision-making. [0003] Since 2007, the first and second phases of soil and water conservation monitoring network and information system construction projects have been launched and implemented nationwide, and the Ministry of Water Resources' soil and water conservation monitoring centers, water and soil conservation monitoring central stations in various river basins, and ...

AI Technical Summary

Problems solved by technology

[0017] There are many links and the process is cumbersome. In each process, you need to be careful, and errors will occur if you are not careful. If drips and sampling bottles are confused, it will directly cause production errors or even lead to test failure.

[0018] It is manpower and time-consuming, sampling after each rain, each observation area must sample three bottles, label them one by one, weigh, measure, dry, re-weigh, and calculate, each observation field has at least ten observation areas, as many as Thirty, after each rain, the workload is very heavy, and it will take at least one working day to complete this work

In addition, the drying duration is longer, which prolongs the working time
