Description
Technical field
The utility model belongs to the studying technological domains such as soil gas diffusion, Soil Trace Gases discharge.
Background technology
The research of soil gas diffusion characteristic, Soil Trace Gases discharge often need form soil gas, concentration carries out Accurate Determining, and accurate acquisition soil gas sample is important prerequisite.Existing acquisition method mainly contains:
1, carry out with the soil gas vasculum that Japan produces, this equipment comprises gas collecting case, Storage Time in Gas Collecting Bag, asepwirator pump, gas collecting pipe, protection tube etc.Concrete acquisition method is, is inserted in protection tube by gas collecting pipe, causes negative pressure, by soil air suction gas vasculum with asepwirator pump.The shortcoming of this kind of method is: price; Equipment is more, and floor area is large; Be not suitable for extensive multi-point sampling; Need electricity be connect, consume the energy; Rainy day sample requirement cannot be met simultaneously.
2, in advance vitrified-clay pipe is imbedded different depth soil, gather with gas production bag, gather after negative pressure need being caused with asepwirator pump or artificial foot-operated attractor.The shortcoming of this kind of method is: because general potter's clay tube head is comparatively large, after placing into the soil, and particularly length of embedment is be difficult to after the soil of below 50cm take out, and is usually can only stay in soil after off-test; Because soil gas collecting device is larger, for reducing the disturbance to soil, can only place into the soil in advance, in the bad movement of duration of test, take up an area more, the asepwirator pump of power supply or artificial foot-operated asepwirator pump etc. need be connect during sampling, therefore have price high, take up an area large, power consumption or effort, operation inconvenience, more difficult operation between crop growing state animated period, very difficult extensive multidraw, be not suitable with the shortcomings such as rainy day sampling.
Utility model content
The utility model is difficult to adapt to Different climate condition for current sampler, a difficult problem for extensive multipoint acquisition different depth soil gas can not be met, proposing one does not need extra power, structure simple, easy to operate, cheap, time saving and energy saving, and is applicable to the harvester of the different depth soil gas that multiple spot is observed simultaneously.
The syringe that the utility model comprises rigidity gas collecting pipe, connecting hose, the first T-valve, the second T-valve, support member and is made up of injection tube and push rod; One end of described rigidity gas collecting pipe is connected to the first end of the first T-valve by connecting hose, the sidewall of the other end of rigidity gas collecting pipe offers some apertures; The injection tube front end of described syringe is connected to the first end of the second T-valve; Second end of described first T-valve is detachable connection with the second end of the second T-valve; After described support member is arranged on and bleeds between injection tube and push rod.
The previous day gas collecting pipe is inserted soil in sampling, make tool foraminate rigidity gas collecting pipe enter the depth of soil needing test, connecting hose and the first T-valve are then exposed to soil upper surface.During sampling, second T-valve is connected with the first T-valve on connecting pipe and communicates, in injection tube, pull out push rod, cause internal negative pressure, and make support member be fixed on appropriate location between injection tube and push rod to maintain negative pressure, soil gas is inhaled in syringe.After soil gas gathers, closed by two T-valve, then be separated by two T-valve, sampling completes.
Because the utility model adopts gas collecting pipe to insert soil, very little to the disturbance of soil, do not need to imbed in advance, only need within one day, to be inserted in soil before sampling.The advantage of this device mainly contains: cheap, simple to operate, efficient, do not need power consumption, time saving and energy saving, decrease the disturbance to soil to greatest extent simultaneously, accurately can collect different depth soil gas, can be applicable to extensive multiple spot gather simultaneously, and be applicable to whole crop growing season, do not limit by crop growing state, also can not impact plant growth.
In addition, inserting soil for convenience, prevent soil in insertion soil course from entering in gas collecting pipe, to make the gas collected be the gas of the required degree of depth, be cecum, and this cecum is provided with tip projection at the rigidity gas collecting tube end arranging aperture.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is by rigidity gas collecting pipe 1, transition conduit 2, connecting hose 3, first T-valve 4, second T-valve 5, support member 8 and the syringe that is made up of injection tube 6 and push rod 7.
One end of rigidity gas collecting pipe 1 is connected to the first end of the first T-valve 4 by transition conduit 2 and connecting hose 3, the sidewall of the other end of rigidity gas collecting pipe 1 offers six apertures 11, be cecum in the end of the rigidity gas collecting pipe 1 arranging aperture 11, and this cecum is provided with tip projection 12.
Injection tube 6 front end of syringe is connected to the first end of the second T-valve 5; Second end of the first T-valve 4 is detachable connection with the second end of the second T-valve 5.
Support member 8(is as spile) be arranged between the injection tube after bleeding 6 and push rod 7.
Soil gas harvester of the present utility model under rice wheat rotation condition different section soil gas concentration gradient, rate of diffusion, distribute rule research in Successful utilization, successful acquisition 8 times in different growing stages, once gather 48 samples simultaneously, overcast and rainyly also can to carry out.This is that other method is difficult to realize.
This utility model achieves low cost, extensive, unpowered original position accurate acquisition different depth soil gas, for the research of discharging soil gas Diffusion Law and Soil Trace Gases provides guarantee.
