Abstract
The utility model provides a kind of anti-pollution soil gas sampler.The utility model comprises drilling rod, in the middle of described drilling rod, there is axial pass-through holes, it is characterized in that: the point of described drilling rod has one group of pore be connected with described axial pass-through holes, the tail end of described drilling rod has the flexible pipe be connected with described through hole, described flexible pipe connects transfer tank top, be provided with free-piston in the middle of described intermediate tank, described intermediate tank top is also connected with gas outlet and sampling bag respectively by pipeline, and the bottom of described intermediate tank connects air pump.The utility model can be avoided being mixed into air and pollute the soil gas taked in the process of sampling.
Description
technical field:
The utility model relates to a kind of environmental monitoring utility appliance, is specifically related to a kind of anti-pollution soil gas sampler.
background technology:
At present, CO in soil
2research become the focus of global carbon research.Gathering soil gas sample is exactly research soil CO
2prerequisite.Forefathers, and the method for location heeling-in sampling bottle that adopts collects soil gas, but the shortcoming of the method wants spoiled soil prototype structure and can not gather soil gas whenever and wherever possible.The basic demand of sampling apparatus, in order to truly, exactly gather gas in soil, necessarily requires during sampling: the primary structure of not spoiled soil during (l) sample, in order to avoid being mixed into of other gas; (2) gas in different depth soil can be gathered whenever and wherever possible; (3) light, the easy transport of sampling apparatus, easy to operate.Soil gas sampler relatively more conventional at present generally adopts drilling rod to connect guiding tube, first uses drilling rod to make a call to a thief hole, then guide wire is put into thief hole in the process of use.Guide wire can be squeezed in the middle of soil with hammer, is finally connected on guide wire interface by plastic tube.This sampler due to the problem of the connection of guiding tube and drilling rod, is inevitably mixed into partial air, affects the accuracy of monitoring result in the process of sampling.
utility model content:
The purpose of this utility model provides a kind of anti-pollution soil gas sampler for above-mentioned Problems existing, can avoid being mixed into air and pollute the soil gas taked in the process of sampling.
Above-mentioned object is realized by following technical scheme:
Anti-pollution soil gas sampler, comprise drilling rod, in the middle of described drilling rod, there is axial pass-through holes, the point of described drilling rod has one group of pore be connected with described axial pass-through holes, the tail end of described drilling rod has the flexible pipe be connected with described through hole, and described flexible pipe connects transfer tank top, is provided with free-piston in the middle of described intermediate tank, described intermediate tank top is also connected with gas outlet and sampling bag respectively by pipeline, and the bottom of described intermediate tank connects air pump.
Described anti-pollution soil gas sampler, the pipeline be connected is respectively arranged with ball valve and unidirectional air outlet valve, described flexible pipe is also provided with ball valve and retaining valve with described gas outlet and described sampling bag.
Described anti-pollution soil gas sampler, described drilling rod top is provided with handle.
Beneficial effect:
1. the utility model is provided with independent gas outlet by surge tank, when drilling rod pierces after in soil, the gas in soil is slowly collected by operation air pump, early stage, the gas collected was due to containing the air in drilling rod, and first open ball valve on gas outlet by its emptying, the ball valve of then closing on gas outlet continues collection gas, gas is not at this time by air pollution, purity is high, and do not have the chance with extraneous contact again in whole device, the soil gas monitoring result of collection is more accurate.
2. the pipeline that of the present utility model with described gas outlet and described sampling bag are connected is respectively arranged with ball valve and unidirectional air outlet valve, further avoid being mixed into of outside air.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure: 1, drilling rod, 2, axial pass-through holes, 3, pore, 4, flexible pipe, 5, transfer tank, 6, free-piston, 7, gas outlet, 8, sampling bag, 9, air pump, 10, ball valve; 11, unidirectional air outlet valve; 12, breather cheek valve; 13, handle.
embodiment:
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.Following embodiment should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.
Embodiment 1:
As shown in Figure 1: the anti-pollution soil gas sampler of the present embodiment, comprise drilling rod 1, in the middle of described drilling rod, there is axial pass-through holes 2, the point of described drilling rod has one group of pore 3 be connected with described axial pass-through holes, the tail end of described drilling rod has the flexible pipe 4 be connected with described through hole, described flexible pipe connects transfer tank 5 top, free-piston 6 is provided with in the middle of described intermediate tank, described intermediate tank top is also connected with gas outlet 7 and sampling bag 8 respectively by pipeline, and the bottom of described intermediate tank connects air pump 9.
Anti-pollution soil gas sampler described in the present embodiment, the pipeline be connected is respectively arranged with ball valve 10 and unidirectional air outlet valve 11 with described gas outlet and described sampling bag, described flexible pipe is provided with ball valve and breather cheek valve 12.
Anti-pollution soil gas sampler described in the present embodiment, described drilling rod top is provided with handle 13.
The course of work of the anti-pollution soil gas sampler of the present embodiment is: first drilling rod is extend into the inside will monitoring soil, booster air pump is bled, free-piston in intermediate tank will move down, residual air in the drilling rod gas be communicated with in soil enters the top of intermediate tank together, when the gas of suction is greater than more than 2 times of drilling rod internal run-through pore capacities, the air of drilling rod inside, surface is washed, certainly more gas can be extracted out in order to degree of accuracy is higher, then gas outlet emptying is passed through, at this time restart slowly to extract soil gas, gas after extraction is sent in sampling bag, whole process does not have the chance with extraneous contact again, the soil gas monitoring result of collecting is more accurate.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned technological means, also comprises and is equal to by above technical characteristic the technical scheme that replacement forms.Unaccomplished matter of the present utility model, belongs to the common practise of those skilled in the art.
