Real-time monitoring device for soil erosion of ravine

Abstract

The invention discloses a real-time monitoring device for the soil erosion of a ravine, which comprises a flume, a force counteracting region and a plurality of settling basins, wherein the flume leads water in the ravine to the force counteracting region, water in the force counteracting region flows into the settling basins, the settling basins are arranged from high to low, and each settling basin is provided with a plurality of drain pipes. The real-time monitoring device is characterized in that each settling basin is provided with 10 drain pipes, the drain pipes are arranged at the same side, the diameter and the length of each drain pipe is equal to one another, one drain pipe of the upper-layer settling basin is discharged into the lower-layer settling basin, and each settling basin is provided with a current type soil monitor. The real-time monitoring device has the advantages that the size of flow can be accurately monitored, the accumulative error can be reduced, the specific numerical value of the soil erosion can be timely monitored, and the device is suitable for the field work.

Description

technical field [0001] The invention relates to the technical field of water and soil monitoring, in particular to a water and soil loss monitoring device. Background technique [0002] With the increasing impact of production technology on the natural environment, the living environment of human beings is facing a huge test, especially the climate is more obviously affected by various waste gases emitted by humans. Therefore, soil and water conservation and forestry construction are becoming more and more important. important. The monitoring of water and soil loss is the basis of the above work, and the monitoring of water and soil loss can provide the necessary design basis for the formulation of water and soil conservation projects. [0003] The Chinese invention patent application number is 200310110900.3, the inventor He Binghui, and the patent titled "Nine-hole diversion water and soil loss monitoring system on natural slope surface" discloses a monitoring device.

[0003] The Chinese invention patent application number is 200310110900.3, the inventor He Binghui, and the patent titled "Nine-hole diversion water and soil loss monitoring system on natural slope surface" discloses a monitoring device. The invention sets up 9 outfalls in Shenshadang And a drain that flows into the next level of sand sinking, because the drain that flows into the next level of sand sinking is not in the same position as the 9 drains, and the process of water inflow and outflow forms a different flow rate in the sinking sand , therefore, the amount of water flowing into the next level of sand sinking can not be equal to one-tenth of the flow of the sinking sand, because the sinking of sand is multi-level, so the cumulative error is huge; in addition, the method for measuring the soil content of the invention is It is also inaccurate to use the silt content of the first-level sand sink as a standard, because although the sand sink can deposit most of the silt, there are still some that flow into the next level of sand sink, which is not considered in this invention, and this The sediment monitoring method requires sampling and drying, and cannot monitor the soil content in real time

However, the real-time monitoring devices controlled by computers are not only expensive, but more importantly, they are not suitable for field operations due to the complexity of the system.
