Technical field
The present invention relates to the test apparatus equipment technical field, is a kind of inflator formula soil profile gas collecting device specifically.
Background technology
As everyone knows, be that the terrestrial climate system change of principal character is a undisputable fact with the climate warming.Under the background of climate warming, Qinghai-Tibet regional ever frost presents degeneration in various degree, possibly cause soil organic carbon that the ever frost district is a large amount of and nitrogen with the form of greenhouse gases (like CO
2And N
2O etc.) get into atmosphere, show positive feedback effect, therefore, study the generation mechanism and the influence factor of Qinghai-Tibet ever frost soil greenhouse gases, have important practical significance for the ecologic environment of control greenhouse gas emission with the protection permafrost region.Frequently take place period at frozen soil mobile layer freeze-thawing process of soil, the greenhouse gases in the different depth soil of position monitor Qinghai-Tibet Platean are the common hot issues paid close attention to of pedology, ecology and cryosphere scientific research person.Research soil greenhouse gases concentration profile distribute and with the relation of soil physico-chemical property, help to disclose that the soil percent of greenhouse gases produces, accumulation, transportation and to the biology and the physical process of airborne release, in global change research due, have great importance.
At present, the researcher mainly concentrates on the flux monitoring of face of land greenhouse gases, and less to the study on monitoring of soil profile greenhouse gases, this mainly receives the restriction of test apparatus.Because the alternate freezing and thawing effect often takes place Qinghai-Tibet ever frost mobile layer soil, through the air admission hole of regular meeting's obstruction gas collecting, this has brought very big obstacle for other porous soil gas collecting device application in this zone during holard glaciation.At present existing researcher utilizes single pore that the different depth of soil gaseous sample is monitored; But because it only represents the soil gas of a certain degree of depth; Be difficult to combine generation mechanism and the influence factor of analyzing greenhouse gases with the soil physico-chemical property of concrete depth range, this has brought very big sum of errors uncertain to test findings.
Summary of the invention
In sum; The object of the present invention is to provide a kind of inflator formula soil profile gas collecting device; This invention overcomes the defective of existing soil gas harvester, can under the field environment that various low temperature, humidity or alternate freezing and thawing take place frequently, use, and improves the accuracy of test.
The objective of the invention is to realize through following technology:
A kind of inflator formula soil profile gas collecting device; Escape pipe, replaceable type filter, the single channel that comprises piston handle, dust cap, protective casing, rubber piston, exhaust tube, minipump, gas production bag, the band syringe needle gentle body collection tube of valve of giving vent to anger; It is characterized in that: the protective casing top is provided with dust cap, and the bottom tube wall is provided with equally distributed air inlet micropore; Be equipped with rubber piston in the protective casing, rubber piston top fixed piston handle; The protective casing outside is positioned at air inlet micropore top and is provided with the arc outlet nozzle; Gas collecting Guan Yiduan is connected with the arc outlet nozzle, and the other end and the single channel valve of giving vent to anger is connected; Exhaust tube connects single channel give vent to anger valve, replaceable type filter and minipump successively; The escape pipe of band syringe needle connects minipump and gas production bag respectively, which is provided with valve.
Advantage of the present invention and beneficial effect:
1, the present invention can be according to the different tests purpose; Be laid in the field soil environment that various low temperature, humidity or alternate freezing and thawing take place frequently; Mainly be to make through extracting piston handle repeatedly that rubber piston produces pressure and heat in the protective casing, avoid soil particle, water and ice that the obstruction of air inlet micropore is disturbed; In addition, the moisture that the arc outlet nozzle helps taking out of in the pumping process is not stored, and after its glaciation the arc outlet nozzle is stopped up preventing.
2, the present invention can be according to the requirement processing inflator formula soil profile gas collecting apparatus of gathering greenhouse gases in a certain depth of soil scope; Gather the soil greenhouse gases of different depth scope, thus the greenhouse gases concentration in each depth range of periodic monitoring soil profile.
3, the present invention can avoid ambient atmosphere to get into the concentration error that the gas collecting pipe is caused through the valve of giving vent to anger at gas collecting pipe upper end installation single channel; In addition, the replaceable type filter of employing can prevent that the steam of bringing in the pumping process from getting into minipump.
4, the present invention bleeds through minipump automatically increases the gas flow of being gathered, and makes it can have enough amounts to come to satisfy fully the testing requirement of different greenhouse gases concentration, improves the test degree of accuracy with this; Simultaneously, there is the escape pipe of valve and band syringe needle the minipump gas outlet, can easily the gaseous sample that is extracted be collected into the gas production bag.
5, the packaged type air-extractor formed by the escape pipe and the gas production bag of exhaust tube, replaceable type filter, minipump, valve, band syringe needle of the present invention, can be after accomplishing the gaseous sample collection dismounting and use at its place.
6, the present invention is simple in structure, easy to operate, be applicable to the field environment (like high and cold permafrost region) that various low temperature, humidity or alternate freezing and thawing take place frequently, and suitable multiple spot is observed simultaneously.
