Description

Portable ground detector Technical Field The utility model relates to the technical field of meteorological equipment, in particular to a portable ground detector. Background In the research of the meteorological field and related business, accurate collection of soil layer samples is a core link for acquiring key data. Parameters such as soil water content, component distribution, vertical structure and the like have irreplaceable effects on weather prediction model construction, weather change mechanism analysis and agricultural weather service optimization. For example, the water exchange process between soil atmospheres can be quantified through layered soil sample analysis, and data support is provided for drought early warning, farmland irrigation scheduling and the like. However, existing soil sampling techniques suffer from significant drawbacks: the traditional sampling equipment has the defects of huge volume and high weight (such as vehicle-mounted drilling equipment), depends on large transportation tools and professional operation teams, is difficult to deploy in complicated terrains or traffic limited areas such as remote mountain areas, plateaus and the like, and severely restricts the global coverage of a meteorological monitoring network. The functional design limitation is that although the portability of the miniaturized equipment is improved, the miniaturized equipment can only collect surface soil and cannot meet the layered sampling requirements of soil layers with different depths. Meanwhile, in the sampling process, oxidation reaction is easy to occur between the appliance material and soil, or sample pollution is caused by structural design defects (such as an open sampling cavity), so that the detection precision of key indexes such as water content is influenced.
