The specific work process of bottom water stratification water sampling device of the invention is as follows：
First, as shown in figure 1, bottom water stratification water sampling device is sling by pull rope 9；The bottom of pull rope is provided with two
Section transition connecting rope, transition connecting rope is connected Ei with suspension ring 81.
Second, seal plug is removed, the spacing ball 32 of each water sampler is put into by the upper end open of vertical cylinder body
In vertical cylinder body, and the 4th connecting rope 33 is set to be placed in corresponding threading breach 16；Then, flat clamp is pressed down, and is made
Flat clamp is resisted against on vertical cylinder upper end face；The opening of each threading breach is sealed and hidden by flat clamp；Followed by, then by seal plug
It is reinstalled in exhaust hole, blocks exhaust hole；Now, water sampler will be hung by spacing ball and the 4th connecting rope
Between vertical cylinder body and flat clamp.
3rd, as shown in Figure 4, Figure 5, the compression spring 37 of annular lug 38 and the 3rd is moved to the same of unblock lever
Side, and annular lug is resisted against on unblock lever；Now, 310 intake chambers are located at collection tube inner side, and extraneous seawater cannot be introduced into
Collection tube.
4th, water acquisition is carried out in the waters specified by being placed under bottom water stratification water sampling device；When seabed water sampling system
In decentralization process in waters, each water sampler will be suspended in waters system by spacing ball and the 4th connecting rope；Such as Fig. 1 institutes
Show.
5th, as shown in fig. 6, after bottom water stratification water sampling device sinks to seabed, release device and triggering device will
Sedimentation counterweight top is suspended in by the first connecting rope 5；And because triggering counterweight 22 is located at the lower section of sedimentation counterweight 7, triggering is matched somebody with somebody
Elder generation is contacted with seabed again；Thus when sedimentation counterweight contacted with seabed after, the first compression spring 210 by upper and lower piston body up
Promote, until upper piston body is resisted against on upper limit projection, so that third through-hole is located at lower piston body lower section, and make first to lead to
Hole, the second through hole and third through-hole are interconnected；Now, the hydraulic pressure of extraneous seawater will be by third through-hole, the second through hole, connection
Pipe and first through hole are applied on lifting piston 12, so that moved on lifting piston, untill being resisted against on positive stop.
When lifting piston is resisted against on positive stop, the spacing between flat clamp and vertical cylinder upper end face is more than spacing
The diameter of ball（Spacing ball can be deviate from by between flat clamp and vertical cylinder body upper end）；Thus now, each water sampler is floating
Floated in the presence of power body, as shown in Figure 6.
As shown in Figure 7, Figure 8, when water sampler floats, and after making the 3rd connecting rope 31 exceptionally straight, the buoyancy of floatage body will
Overcome the elastic force of the second compression spring 320, make pushing piston drive unblock lever 318 move down, until pushing piston against
Untill on the second collar stop 322；Now the end of unblock lever 318 is located at the outside of annular lug end face, and the 3rd
Sealing ring 317 is still resisted against on unblock lever side.
After the end for unlocking lever is located at the outside of annular lug end face, the past collection of the annular lug of the 3rd compression spring 37
The other end passage of cylinder, and annular lug is resisted against the end of collection tube；Intake chamber will be by following shape in this process
State：One end of intake chamber 310 is located at collection tube outside, and the other end is located at collection tube inner side（As shown in Figure 7）；Now, extraneous sea
Water will have intake chamber to enter in collection tube.When annular lug is resisted against the end of collection tube, sliding shaft rod will again with second
Sealing ring fitted seal.So far water sampling is completed.
The length that the present invention can lead to the 3rd connecting rope 31 of control controls the spacing between collection tube and seabed, so that
The convenient, water sample accurately gathered in the specific range of seabed top.
6th, after completing water sampling, operator can be by drawstring 61 toward pull-up（The upper end of drawstring is reserved on the water surface
Side）, grafting lever 63 is pulled out；So as to sedimentation counterweight be discharged；After counterweight release is settled, bottom water stratification water sampling device will
The automatic top under buoyancy.
Bottom water stratification water sampling device of the invention is equally applicable to be applied in other waters.
