Meanwhile, dust aerosol entering the atmosphere due to wind erosion has become a significant climate problem in the whole northern area. It is estimated that the annual amount of sand in our country is about 0.8 Gt. A large amount of sand dust particles can not only directly pollute urban environment, but also serve as cloud condensation nuclei to influence cloud formation and precipitation, and also directly influence the sunshine amount or influence regional climate and global climate through radiation forced effect.
The sand collector is used for measuring the sand conveying amount and the structure of the sand flow in the sand flow, can observe the change of the sand conveying rate along with the height, provides a basis for accurately knowing and mastering the motion property of the sand flow, and plays an important role in guiding wind erosion prevention and control and evaluating prevention and control effects.
The existing sand collector mainly comprises a cyclone separation type sand collector, a multi-opening square opening type sand collector, a tipping bucket type sand collector and the like. The cyclone separation type and tipping bucket type sand collecting instruments are usually used for single-point (layer) measurement, are not easy to be made into a structure with a longitudinal section for multi-layer measurement, and are not beneficial to measuring the sand conveying amount and the wind and sand flow structure.
The multi-opening square opening type is the most common profile sand transportation measuring device, and has the problems that the sand collection amount needs manual measurement and manual emptying, the continuous measurement function cannot be realized, the wind speed of each sand collection opening (namely each layer) cannot be accurately obtained, and only the average wind speed can be used for processing, so that the calculation of the sand transportation amount and the wind sand flow structure is influenced.
Therefore, the design of the multifunctional sand collector capable of fully automatically measuring the layering of the longitudinal section (including the parameters such as sand collection amount, wind speed and the like) has important significance for the research of wind erosion prevention and control.
