There is simple and compact for structure, convenient to use, maintenance cost is low, service life is long, failure rate is low etc..
To achieve the above object, the utility model provides following technical solution：The underground sampling Detection device includes shell
Body, fluid pump module, sampling module I, flow-control module, sampling module II, divides the power module being successively set in housing
Module, pressure adjusting module, detecting module are analysed, is mutually linked, is characterized in that by sample introduction pipeline between each module：Fluid
Pump module includes hydraulic pump, a pair of of the hydraulic cavities being connected respectively with hydraulic pump, the double-head piston being arranged between hydraulic cavities, liquid
Pressure chamber is also connected, and check-valves is set on connecting pipeline with sampling module I or sampling module II respectively；Sampling module I or
Sampling module II includes the sample tanks equipped with piston, is separated by sample tanks piston inside sample tanks, sample tanks both ends respectively with
Sample introduction pipeline is connected, and is isolated by valve；Flow-control module includes the flow tank being connected with sample tanks, is held in the mouth with flow tank
The hydraulic tank connect is separated inside flow tank by piston I, is separated inside hydraulic tank by piston I I；Detecting module include probe,
Resistivity sensor, the pressure converter being electrically connected with probe.
The beneficial effects of the utility model：By setting valve on the corresponding position of sampling pipeline, by the sample after sampling
This segmented seal, maintains original pressure environment of sample, and passes through photometering and resistivity is detected sample, so as to
The precipitation of bubble is effectively prevented, ensure that the accuracy of measurement result.

Label）It is mutually linked.Wherein, fluid pump module includes hydraulic pump 9, a pair of of the hydraulic cavities being connected respectively with hydraulic pump, setting
Double-head piston 13 between hydraulic cavities, hydraulic cavities are also connected, and in communicating pipe with sampling module I or sampling module II respectively
Road sets several check-valves 12（The present embodiment is four）, it is equipped between tube outlet 10 and sample introduction pipeline to be measured for observing
The observation window 11 of 14 mobility status of sample.Sampling module I or sampling module II includes the sample tanks 18 equipped with piston, in sample tanks
Portion passes through sample tanks piston（Attached drawing is unmarked）Separate, it is water that side, which is sample opposite side, sample tanks both ends respectively with sample feeding pipe
Road is connected, and valve body 19, and the valve by being located at sample feeding pipe road are equipped between the sample side of sample tanks and sample introduction pipeline（It is attached
Scheme unmarked）Isolation.Flow-control module includes the flow tank being connected with sample tanks（Attached drawing is unmarked）, be connected with flow tank
Hydraulic tank（Attached drawing is unmarked）, water end (W.E.) and hydraulic oil end are separated by piston I 20 inside flow tank, water end (W.E.) and sample tanks
Water end (W.E.) is connected, and sets electric control valve（Attached drawing is unmarked）.Inside hydraulic tank by piston I I 21 be separated into hydraulic oil end and
Mortar end.Detecting module includes probe 15, the resistivity sensor 16 being electrically connected with probe 15, pressure converter 17, optics
Detection module（It is not shown in figure）.
In use, detection device is integrally sent into drilling, flow pump module, will by popping one's head in using hydraulic pump as driving force
Sample to be tested is evacuated in sample introduction pipeline, and carries out Preliminary detection to the resistivity of sample first, to determine sample as mortar or water
Or oil, if not mortar then continues to carry out downwards, sample is pumped to sample tanks, sample tanks are adjusted by flow-control module
Interior water, and then the position of sample tanks piston is adjusted, the final adjusting realized to sample pressure is arranged gas by valve body 19
Go out, the absorbance of sample is then detected by the optical detecting module in detecting module, and then determine that it is water or oil, reach and survey
Visit the purpose of detection.To avoid the uncertainty of sample, multiple sampling modules are additionally used, wherein sampling module I is that single storehouse is tied
Structure, sampling module II is more chamber structures, so as to be detected simultaneously to multiple samples, improves accuracy of detection.
