Place also needs to detect the gas componant content that contains in body of groundwater, but the sealing of existing underground laden water collecting device compared with
Difference, is usually directly directly gathered using wide-mouth bottle in the port or liquid cell that fluid flows out, substantially without sealing property,
Incompressible gas and the most of volatilization of insoluble gas and escape in fluid, it is impossible to adopted to the gas phase atmosphere in underground fluid
Collection, is that later work is made troubles so as to the exact level of each composition in underground fluid cannot accurately be known.
On the one hand, if containing toxic and harmful in underground current, gas is escaped and is not detected in detection process,
Toxic and harmful will injure personal safety with direct body contact during the utilization in future.So accurate detection ground
Gas phase composition in lower fluid is very necessary.On the other hand, many underground water fetch water during, especially many temperature compared with
In the gatherer process of underground water high, requirement is not reached with collection capacity because the evaporation of moisture causes acquisition time to increase, to adopt
Collection work brings difficulty.

The course of work of the invention is further explained below：
When in use, drive first piston 100 and second piston 200 respectively along the first collection by compression handles first
The inwall of the collection room 20 of room 10 or second compresses downwards, so as to the first collection room 10 and second to be gathered the gas inside room 20
Discharge, after the completion of gas discharge, compression handles is accommodated in inside compression handles draw-in groove 8.And gas is extracted by vacuum extractor
Air in body collection tube 4, makes gas collecting pipe 4 keep vacuum state.
Slide switch on catheter 2 and gas collecting pipe 4 is in open mode, by the first end 21 of catheter 2
The funnel 23 of end is connected to the exit of gas-liquid mixture, and gas-liquid mixture enters first and gathers in room 10 by catheter 2
Portion, due to the effect of funnel 22, gas-liquid mixture can slowly enter, so as to avoid leakage or loss.With the first collection room
The increase of the volume of gas-liquid mixture in 10, first piston 100 with hydraulic pressure effect along first collection room 10 side wall to
Upper slip, when the gaseous volatilization in gas-liquid mixture, gas is entered in gas collecting pipe 4 by through hole 6, and eventually enters into the
Two collection rooms 20 in, second piston 200 with air pressure effect along second collection room 20 side wall upward sliding, with first
The increase of the gas-liquid mixture in room 10 is gathered, eventually some liquid enters in gas collecting pipe 4 with the gases, led to
Cross transparent observing form and graduated scale it can be seen that first collection room 10 in liquid volume, when first collection room 10 in
Behind space of the liquid full of whole collection room, the slide switch on catheter 2 is closed, now whole gatherer process terminates.
Slide switch on gas collecting pipe 4 is closed, and the junction of the second bending section 44 and the second vertical portion 45 is opened,
Gas can be gathered from the first end of the second vertical portion 45 by sampler 3, or chamber interior is gathered first by sampler 3
Collection liquid.Sampler is placed in sampler draw-in groove 300 in the not used time, and sampler draw-in groove 300 is with compression handles draw-in groove 8 simultaneously
Row are arranged on the top of collection room.
The present invention can be applied in multiple fields, to collection GEOTHERMAL WATER, the liquid containing hydrogen sulfide gas, methane-containing gas
Liquid etc., sealing collection well can be accomplished, so as to analyze the composition of gas in advance in real work, prevented poison gas
Body is leaked.
Application of the invention is further explained as a example by gathering geothermal fluid sample below：Typically wrapped in geothermal fluid
Include GEOTHERMAL WATER and hydrogen sulfide (H2The gas such as S).
Because hydrogen sulfide gas have severe toxicity, even if thin hydrogen sulfide (specifies, sulfureted hydrogen gas concentration will in industrial production
Less than 0.01mg/L) also there is stimulation to respiratory tract and eyes, and headache can be caused, and the concentration for working as hydrogen sulfide reaches
During 1mg/L or higher, then threat can be produced to life.
Therefore, in gatherer process, if be directly acquired with wide-mouth bottle, sulfureted hydrogen gas concentration prior-warning device can only
The hydrogen sulfide gas in GEOTHERMAL WATER are detected the presence of, that is, stink damp present in the GEOTHERMAL WATER gathered in wide-mouth bottle
Body.But, during actual acquisition, after reaching ground from underground due to geothermal fluid, temperature and pressure all there occurs change,
There is a big chunk stink damp to know from experience volatilization in geothermal fluid to escape, it is impossible to acquisition testing, cause sulfureted hydrogen gas concentration pre-
The concentration of hydrogen sulfide that alarm device is detected is less than actual concentrations, consequently, it is possible to it is too high and jeopardize life sulfureted hydrogen gas concentration occur
Life.
And utilize the present apparatus to gather geothermal fluid, then geothermal heat flow can be collected with the second collection room by the first collection room
All of hydrogen sulfide gas in body.If it find that the content 0.01mg/L of hydrogen sulfide gas or it is higher when, it should user is carried
Go out warning, finish geothermal fluid in collection and carry out using preceding, it should at hydrogen sulfide gas contained in geothermal fluid
Reason.If detecting sulfureted hydrogen gas concentration less than 0.01mg/L, also to prevent 0.01mg/L from assembling in workplace, reach danger
The concentration of victimization body, so as to be detrimental to health.And need that sulfureted hydrogen gas concentration prior-warning device is installed in workplace,
When sulfureted hydrogen gas concentration reaches the lower limit that the mankind can bear in environment, sulfureted hydrogen gas concentration prior-warning device will send police
Report, staff will at once withdraw scene.
Simple structure of the present invention, easy to use, integrally-built good seal performance, can adopt to gas-liquid mixture
Collection, effectively prevents the volatilization and leakage of gas in gas-liquid mixture, so as to the problem for avoiding gathered data inaccurate.The opposing party
Face, because gas-liquid mixture can be separated in the first collection room and the second collection room, not resulting in the first collection room cannot gather
The situation of full liquid occurs.
Finally it should be noted that：Above-described each embodiment is merely to illustrate technical scheme, rather than to it
Limitation；Although being described in detail to the present invention with reference to the foregoing embodiments, it will be understood by those within the art that：
It can still modify to the technical scheme described in previous embodiment, or which part or all technical characteristic are entered
Row equivalent；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the present invention technical side
The scope of case.
