Portable simulation test device for monitoring water and soil erosion in real time

Abstract

The invention discloses a portable simulation test device for monitoring water and soil erosion in real time. The device comprises a rainfall system, a soil tank device and a runoff data real-time acquisition system; the rainfall system comprises a water storage tank, a water supply pipe, a water pump, a flow meter, water tank supports, a rainfall water tank, a water drop generator and a liquid level indicator pipe; the soil tank device comprises rolling wheels, a support, a soil tank, a slope indicating dial and a lifting device; the runoff data real-time acquisition system comprises a collecting pipe, a runoff barrel, an electronic scale and a notebook computer with built-in data record software. By means of the portable simulation test device for monitoring the water and soil erosion in real time, indoor simulation and measurement of soil and water loss on a slope surface can be achieved, the test raininess and the soil tank slope are easy to adjust, operation is easy and reliable, data are accurate, and the data are measured and stored in real time.

Description

technical field [0001] The invention relates to a soil erosion simulation rainfall test device, in particular to a portable real-time monitoring water and soil loss simulation test device. Background technique [0002] Soil erosion is a serious ecological problem in our country. The 2010 Bulletin on the State of the Environment in China shows that the area of ​​soil erosion in my country has accounted for 37.2% of the total land area, reaching 3.5692 million km 2 . As the country attaches great importance to the control of water and soil loss, typical monitoring points have been set up in the main areas of water and soil loss to observe the state of water and soil loss, and a large amount of observation data has been accumulated, which provides great support for the comprehensive prevention and control of water and soil loss. Before the middle of the 20th century, the research on soil erosion mostly relied on natural rainfall. Due to the long time required for natural rain...

AI Technical Summary

Problems solved by technology

[0004] There are many kinds of existing soil erosion simulation test devices, but there are still many disadvantages, such as: (1) each part of the simulated rainfall device is bulky, heavy and fixedly connected, which brings inconvenience to use and transportation; (2) the simulated rainfall During the process, the uniformity and stability of rainfall cannot be satisfied; (3) The runoff volume often obtained in soil erosion experiments is only the final result and cannot reflect the runoff volume in real time
