Portable erosion gully measuring instrument

Abstract

The invention relates to an instrument for measuring a soil erosion gully, which aims to provide a measuring instrument with the characteristics of high measuring accuracy, high measuring efficiency, automatic measurement of wireless transmitted data, convenient transport and lower cost. The invention has the technical scheme that the portable erosion gully measuring instrument comprises a control circuit, a battery, a stand, a trolley and a laser distance measuring instrument, wherein the stand is arranged on the ground of the erosion gully; the trolley is positioned on the stand and can move along the stand; the laser distance measuring instrument is installed on a wheel stand of the trolley, vertically measures the height of the ground soil, and transmits the measured data to terminal equipment in a wireless transmission mode; the stand comprises a horizontally suspended beam and supporting feet for supporting both ends of the beam; the trolley comprises a bearing structure and an actuating mechanism, wherein the bearing structure is used for hanging the wheel stand of the trolley, and the actuating mechanism acts with the stand to generate driving force to move the trolley; two supporting edges used as guide rails are produced on the beam; and the bearing structure comprises a plurality of pairs of rollers which are supported by the supporting edges and are positioned in an inner cavity of the beam.

Description

technical field [0001] The invention relates to an environmental monitoring instrument, in particular to an instrument for measuring soil erosion ditch. Background technique [0002] Slope erosion ditch monitoring is the traditional content of soil erosion micro-monitoring, and it is the basic link of quantitative research on slope soil erosion. The slope surface is the most basic geomorphic unit of the soil erosion area, and soil erosion gullies such as rills, cuts, and gullies on the slope surface are the basic micro-geomorphology of the water erosion area. Gully erosion plays an important role in soil erosion. Studies have shown that the sediment yield of gullies dominated by incised gullies can account for up to 94% of the total sediment yield in the watershed. In order to effectively prevent and control erosion gullies, it is first necessary to accurately grasp the development and change process of erosion gullies. [0003] Erosion ditches develop on eroded slopes, an...

Problems solved by technology

However, since the 3D laser micro-geomorphology scanner needs to provide continuous three-dimensional 3D terrain, the design and operation process is complicated, but the operation is cumbersome, the cost is high, the economical practicability is not high, and it is bulky and inconvenient to carry and use.

[0011] To sum up, in the field of erosion gully monitoring, which is closely related to the process of water and soil loss, there is still no set of accurate and efficient monitoring technology and equipment that can be popularized and applied.
