Description

Technical Field

[0001] The utility model relates to the technical field of sand collectors, in particular to a load-bearing sand collector. Background Art

[0002] The main reason for land degradation in arid and semi-arid regions is soil wind erosion. The main external cause of soil wind erosion is sand activity, and the direct index reflecting the intensity of sand activity in soil wind erosion is sand flux. Monitoring of near-surface sand activity is the main content of ground monitoring of soil wind erosion, which mainly monitors the sand flow. The monitoring results can provide basic data for soil wind erosion detection and prediction. At present, the detection technologies for sand flow at home and abroad are mainly divided into three categories: the first category is to indirectly observe the intensity of sand flow using pressure sensors, sound sensors or optical sensors, etc.; the second category is to directly observe using mechanical sand collectors (such as flat-mouth sand collectors, multi-way square-mouth sand collectors, MWAC sand collectors, cyclone separation sand collectors, etc.) to quantitatively and directly observe the intensity of sand flow; the third category is to collect sand using an integrated sand collector, and integrate an electronic instrument with a mechanical sand collector to weigh and record the weight of dust. The first category has a high degree of automation and can monitor the relative intensity of sand flow in real time (such as dust concentration, number of saltating particles and energy, etc.), but it cannot obtain accurate sand flux from the weight; the second category can accurately measure the sand flux, but it requires a cumbersome manual sand collection process, so it is difficult to conduct real-time monitoring and automatic recording of sand flux with high time resolution; the third category can realize real-time automatic monitoring of dust data.
