Embodiment Construction

[0033] The specifically designed portable erosion ditch measuring instrument includes a control circuit and a battery, and also includes a frame 1 arranged on the ground of the erosion ditch, a trolley 2 positioned on the frame and movable along the The height of the ground soil is measured and the measured data is sent to the laser rangefinder 40 of the terminal device through wireless transmission. Wherein, the battery (omitted in the figure) is a rechargeable lithium battery, which is the power supply of all electrical appliances in the monitor. The battery adopts a capacity of 12.6V5.5AH, which ensures that the system can work continuously for more than 5 hours without charging. The charging adopts AC 220V power supply for regular charging, and the charging current is 2A.

[0034]In the described frame mechanism: the bottom ends of the two legs 3 are used to vertically insert into the ground for fixing, and the connectors 3-3 at the tops of the two legs are inserted horiz...

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...
