The bottle liner type water layer sampling thief that the utility model provides has following advantage:
1, the utility model arrives predetermined water layer post-sampling, can effectively control sampling depth, not limited by field condition, does not need power supply, easy and simple to handle, and is easy to carry.
2, the utility model can be controlled with single rope, has avoided the winding problem of duplex type.
When 3, using the utility model, can on-the-spot sterilize, the other problems that reduces the transfer of water sample and produce therefrom is more suitable for the collection of microorganism water sample.
4, the counterweight head of She Zhiing has increased the weight of sampling bottle, is convenient to be sunken in the water, make adopt water sample more even.
5, sampling bottle can be changed unlike material according to sampling request.
6, the utility model is applicable to the sampling condition of various complexity, and in the bank sampling, ship up-sampling and sewage sampling have more advantage.
7, the utility model is the water-quality sampler that is applicable to deep water, flows anxious and hard sandy riverbed.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further, but the utility model is not limited to following examples.
As shown in Figure 1, bottle liner type water layer sampling thief of the present utility model comprises sampling bottle 1, ball float 2 and pull bar 3; Wherein, sampling bottle 1 an outer sheathed housing 4 is used to seal sampling bottle 1; Bottom at housing 4 connects a balance weight body 6, to increase the gravity of this sampling thief; Top at housing 4 connects a loam cake 5; One end of pull bar 3 is connected by the bottleneck of valve spring 8 with sampling bottle 1, and loam cake 5 is positioned at outside the valve spring 8; Ball float 2 is set on the pull bar 3, and this ball float 2 can move along pull bar 3; A sheathed cylindrical shell 7 on the pull bar 3 between the bottleneck of this ball float 2 and sampling bottle 1, and this cylindrical shell 7 also can move along pull bar 3; Be provided with draw-in groove a9 with this corresponding pull bar 3 in cylindrical shell 7 positions, this draw-in groove a9 is along the circumferential setting of pull bar 3, and is provided with steel ball 11 in the draw-in groove a9, and when not entering in the water, steel ball 11 blocks pull bar 3, and it can not be relatively moved; The place, end of the cylindrical shell 7 of close sampling bottle 1 is provided with draw-in groove b10, and draw-in groove b10 is along the circumferential setting of cylindrical shell 7; When this ball float 2 come-ups, steel ball 11 can enter to from draw-in groove a9 among the draw-in groove b10, and in this sampling thief entered process in the water, pull bar 3 can be at buoyancy of water effect float downward, thereby valve spring 8 is compressed; The bottleneck of sampling bottle 1 is provided with opening a12, cylindrical shell 7 is provided with opening b13, and loam cake 5 is provided with opening c14, when valve spring 8 is compressed and drop to predetermined water layer, opening a12, opening b13 and opening c14 can be positioned on the surface level, promptly realize the collection of water sample.
As shown in Figure 5, when bottle liner type water layer sampling thief of the present utility model uses, can cooperate with take-up and pay-off device 15; As shown in Figure 2, when this sampling thief did not enter in the water, steel ball 11 was arranged in draw-in groove a9, thereby pull bar 3 can not move, and then opening a12, opening b13 and opening c14 are not on the surface level, can not intake.As shown in Figure 3, after this sampling thief enters in the water, in the process that sampling thief descends, ball float 2 come-ups, then cylindrical shell 7 is also along with ball float 2 come-ups, when cylindrical shell 7 rises to when making draw-in groove a9 corresponding with draw-in groove b10 position, then steel ball 11 enters to from draw-in groove a9 among the draw-in groove b10, and then pull bar 3 can move under the buoyancy of ball float 2; Because sampling thief continues to descend in water, retractable cable is not maximum tension, so the opening of not opening under the effect of valve spring 8, at this moment winding wheel evenly freely under the pulling force, has guaranteed that retractable cable is not subjected to the pulling force of maximum at sampling thief.As shown in Figure 4, when water layer was scheduled in sampling thief arrival, retractable cable was subjected to maximum pulling force, force valve spring 8 compressions, and then opening a12, opening b13 and opening c14 are positioned on the surface level, the collection of water sample be can realize, thereby the retractable of a rope, the effect of opening valve realized.
