Description
Affiliated technical field
The utility model relates to a kind of portable soil air in-situ acquisition device, belongs to soil water experiment and gas collecting technical field, is suitable for the collection of soil air in the researchs such as soil environment monitoring in the different habitats, ecosystem management, soil greenhouse gas emission.Be particularly useful for the abominable high and cold meadow of environmental baseline, as the soil air collection of multiple different study areas such as tundra, high and cold wetland, high and cold grassy marshland, high-cold steppe.
Background technology
Soil air is not only the basic research content of pedology as the important component of soil, also is an important envirment factor.Physics and chemistry natural disposition matter and process thereof in situations such as the composition of soil air, quantity and the soil are closely related, to the important influence of growing of root system of plant.As one of important atmosphere " carbon source ", the soil air greenhouse Gas Emission is to the Global climate change important influence, simultaneously soil air also be earthquake, an important content in the research of ore deposit.Soil air research is an importance in the subject researchs such as pedology, environmentology, ecology, hydrology, geology, geography, and the collection of soil air is the basis of soil air research.
Soil air is at below ground, thereby the soil air collection does not have the atmosphere collection so convenient.Tradition soil air acquisition method carries out methods such as indoor soil air extraction and plenum chamber as gathering original position soil, can not fully truly reflect the actual environment in the soil, the residual Atmospheric components of sampling thief meeting, and error is bigger; And carry inconvenience, destructible soil texture.Less but the complex structure of the equipment error that has or rely on infrastructure such as electric power too much is not suitable for environmental baseline field complicated and changeable and carries and use.Zheng Leping (1999) proposes a kind of soil gas sampling apparatus, this device comprise pierce, degas, check and connect collect four parts (Zheng Leping. DEVELOPMENT OF A SOIL GAS SAMPLING DEVICE [J], geology earth journal .1999, (1): 113-114).Patent about the soil air collection has much in recent years, be 201110198618.X, a series of patents of 200810242984.9 etc. as application number, but the influence of fine particle and soil solid matter was a difficult problem in the soil air sampling always when the holard disturbed and extract the interior face of land of collector air, can vacuumize removal face of land air and can prevent that again the soil air sampling apparatus of soil water infiltration from rarely having report.
The utility model content
The utility model is in order to overcome the sampling of soil air in the past destructible soil texture, the impure defective of sampling, and a kind of efficient, laborsaving, low-cost, portable soil air in-situ acquisition device of soil texture only being had Wicresoft is provided.It is characterized in that: one-piece construction is the multi-level nested structure of tubulose, vertical bottom-up pipe cap, gas production window, collection chamber, ground sheath, barometer, plug, air valve and the wireway of comprising successively, wherein collection chamber one end seals with pipe cap, the other end seals with plug, wireway is installed on the plug, be furnished with air valve on the wireway, sheath place in ground arranges barometer.
Wherein, gas production windowsill xsect is provided with mutually nested 5 layers from inside to outside, is followed successively by: collection chamber inner pipe wall sieve shape props up that sheath, internal layer stainless (steel) wire prop up sheath, waterproof ventilated membrane interlayer, outer stainless (steel) wire props up sheath and collection chamber outer tube wall sieve shape props up sheath.
Advantage of the present utility model and benefit:
1. the utility model only has Wicresoft to soil texture, can reduce effectively the original position soil air gather in the influence of fine particle solid material in atmospheric air and soil moisture and the soil, effectively control sampling error.
2. the utility model can be removed air remnants in the face of land in the collector fast; The waterproof ventilated membrane interlayer can prevent that the soil moisture infiltration from influencing the soil gas collection; The internal layer stainless (steel) wire props up sheath can supporting waterproof ventilated membrane interlayer, the opposing negative pressure; Outer stainless (steel) wire prop up sheath can barrier soil in the solid fine grain material damage waterproof ventilated membrane and enter collection chamber; Collection chamber inner pipe wall sieve shape props up sheath and collection chamber outer tube wall sieve shape and props up sheath and can prevent from direct friction between waterproof ventilated membrane interlayer and the soil from playing fixedly protective effect.
Vertebration, manufacture craft is simple, with low cost, easy operating, highly efficient durable, easy to carry.
