Soil erosion real time monitoring instrument

Abstract

The invention relates to a soil erosion real-time monitoring device. The invention is aimed at providing the device which is characterized in high monitoring accuracy, high monitoring efficiency, and capability of automatic sampling, automatic weighing and wireless data transmission to meet the requirements of side monitoring. The technical proposal comprises the following steps that: the soil erosion real-time monitoring device comprises a machine frame, a water inlet mechanism, a weighing mechanism, a water pouring mechanism, a cell and a control circuit; the main frame in the control circuit is connected with each electric control components through an input output interface; the weighing mechanism comprises a weighing sensor which is suspended through at least one suspending connecting device, a weighing rack and a weighing tipper; the water pouring mechanism comprises a rotating shaft on the weighing rack, a tipper shifting block in coaxial coupling with the rotating shaft, a tipper motor positioned on the weighing rack and a tipper shifting lever on a tipper motor shaft; the water inlet mechanism comprises a mobile pipe motor, a shifting fork on a mobile pipe motor shaft anda mobile pipe which is held by the shifting fork and is suspended above the weighing tipper. The suspending connecting device is a universal joint or a weighing connecting hinge.

Description

technical field [0001] The invention relates to an environmental detection instrument, in particular to a real-time soil erosion monitoring instrument. Background technique [0002] Soil erosion is the most serious ecological environment problem in our country, and soil and water conservation is a basic national policy of our country. In order to prevent soil erosion, it is necessary to measure the amount of soil erosion and grasp the law of erosion. Slope runoff formed by natural precipitation erodes soil, carries and scours soil particles, and is the main type of soil erosion. How to accurately measure the content of transported and suspended sediments in runoff on the spot is a thorny issue. At present, the main methods and technical means for surface monitoring of water and soil loss are the runoff plot monitoring method and the bayonet station monitoring method. These two methods rely on the sedimentation of the grit chamber, which is cleaned, collected, dried and wei...

Problems solved by technology

[0004] (1) Using outdated manual measurement methods, high operating costs and low work efficiency;

[0005] (2) The measurement cycle is long, the required facilities and tools are as many as 20 items, the process is complicated, and the measurement accuracy is low;

[0006] (3) It can only measure the total amount of soil erosion, but cannot monitor the dynamic process of soil erosion, and it is difficult to establish the relationship between the soil erosion process and the rainfall process;

[0007] (4) The measurement results rely too much on the monitoring personnel, are easily affected by human factors, and it is difficult to realize the scientificity and reliability of the monitoring results
