Depthkeeping Stratified Sampling operating procedure is as follows：The first step, the first layer fluid close to the water surface is obtained, the control of the first tube-in-tube 11.1
First storage stream container 8.1 floats on the water surface to obtain the first layer representativeness fluid close to the water surface by the first pipe collar 7.1, and leads to
Cross rotating shaft control length of pipeline and read its depth selection；Second step, obtain innermost third layer fluid (close to water bottom such as
Underground water well shaft bottom, earth's surface river river bed, reservoir lake lakebed, or required maximum depth selection) third layer fluid, the 3rd
The maximum sampling that the 3rd storage stream container 8.3 that tube-in-tube 11.3 controls is deposited in water bottom by the first plummet 10.1 or specified
Depth, so as to obtain most deep third layer representativeness fluid, and length of pipeline is controlled to read its depth selection by rotating shaft；3rd
Step is the second layer fluid for obtaining intermediate layer position, passes through the of the third layer fluid of maximum depth selection and minimum sample depth
One layer fluid judges, chooses suitable intermediate layer second layer depth selection, and such as maximum depth selection and minimum sample depth are put down
Average, or the setting value that technical staff judges according to actual conditions, the second tube-in-tube 11.2 is controlled to make the second storage fluid capacitance by rotating shaft 6
The check valve 9.2 of device 8.2 and second reaches designated depth waters, obtains the second layer representativeness fluid of this layer of bit depth, so as to complete
Into the depthkeeping Stratified Sampling operation of three different layers positions.
It is worthy of note that in the present invention, to illustrate the depthkeeping Stratified Sampling device for conveniently only giving 3 different layers positions
Embodiment, by same design philosophy and method processing can obtain 2-10 layers even more layers position depthkeeping layering take
Sampling device；Corresponded to respectively in addition, the implementation case provides 3 different depth selections：(first layer), water-bed (third layer) at the water surface
And corresponding intermediate depth (second layer), only illustrate as case, the specific depth selection of actually each layer position can be according to technology people
Member's will is arbitrarily selected on the premise of no more than range.
A kind of operation principle of portable fluid depthkeeping Stratified Sampling device provided by the invention is as follows：
Connected by embodiment of the present invention, open nitrogen cylinder, the high pressure nitrogen of constant output pressure stimulates the menstrual flow first by four
The first tube-in-tube, second are respectively enterd after nested type diversion mechanism, the second nested type diversion mechanism, the 3rd nested type diversion mechanism
Tube-in-tube, the 3rd tube-in-tube, and then the representative fluid of first layer, the second layer, third layer different depth is obtained simultaneously.Its individual layer
Specific sampling work principle illustrates so that the second layer samples as an example：The representative fluid of designated depth passes through the second check valve in water body
Into the second storage stream container, through the high pressure nitrogen that the second tube-in-tube enters because the second check valve of setting only allows list from the bottom to top
Limited to circulating function by the fluid displacement in the second storage stream container to earth's surface, the fluid is through the four mouthfuls of threeways of the second nested type
Diversion mechanism and the second sample connection enter the second sampling bottle, so as to obtain the representative fluid of the second layer depth.In summary,
Equipment is connected into setting by application claims, nitrogen cylinder is opened and pressurizes, it is deep that each sampling bottle at earth's surface obtains three differences simultaneously
The representative fluid of degree, so as to complete depthkeeping Stratified Sampling.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
