Unblock lever 318 is up moved, until pushing piston is resisted against on the second collar stop 322；Now unlock the end of lever 318
Positioned at the outside of annular lug end face（As shown in Figure 5, Figure 6）.
When annular lug and the 3rd compression spring are moved to the same side of unblock lever, the intake chamber is located at collection tube
Inner side.When convex annular is resisted against the end of collection tube under the effect of the 3rd compression spring, intake chamber is located at collection tube outside.
The specific work process of the airtight fidelity harvester of water sample of the present invention is as follows：
First, as shown in figure 1, the spacing ball 32 of each water sampler is put into into triggering cylinder body by the upper port of triggering cylinder body
It is interior；Then, upper piston body is pushed in triggering cylinder body, for stopping spacing ball, it is to avoid spacing ball is taken off by cylinder body upper port is triggered
Go out；Followed by auxiliary stopper lever 15 being inserted in limiting through hole, for stopping that upper piston body is removed outward；
As shown in Figure 3, Figure 4, the compression spring 37 of annular lug 38 and the 3rd is moved to into the same side of unblock lever, and is made
Annular lug is resisted against on unblock lever；Now, 310 intake chambers are located at collection tube inner side, and extraneous sea water cannot be introduced into collection tube.
Second, as shown in figure 1, the airtight fidelity harvester of water sample is sling by pull rope 23；The lower end of pull rope
It is connected with the suspension ring being connected on push rod 22.
After pull rope slings water sample airtight fidelity harvester, by auxiliary stopper lever 15 by taking in limiting through hole
Go out.
After pull rope slings water sample airtight fidelity harvester, triggering counterweight make lower piston body move down and
It is resisted against on lower limit projection；Now upper piston body is located in the triggering cylinder body above upper limit projection, for stopping spacing ball,
Avoid spacing ball by trigger cylinder body upper port abjection.
3rd, carry out in the waters specified water acquisition by placing under the airtight fidelity harvester of water sample；When water sample it is airtight
In decentralization process in waters, each water sampler will be suspended on waters to fidelity harvester by spacing ball and the 4th connecting rope
It is interior.
4th, as shown in figure 5, after the airtight fidelity harvester of water sample sinks to seabed, triggering counterweight will first with
Seabed contacts, and then the airtight fidelity harvester of water sample continues to sink under sedimentation counterweight effect, until sedimentation counterweight is sunk
To seabed；And in this process, the first compression spring 18 will promote upper and lower piston body up to promote, until lower piston
Till body is resisted against upper limit projection 13.
Instantly when piston body is resisted against upper limit projection, upper piston body is located at the top of the upper surface of triggering cylinder body, and
Diameter of the spacing between the upper surface of upper piston body and triggering cylinder body more than spacing ball；Spacing ball can be by triggering cylinder body upper end
Mouth abjection, now, each water sampler sinks under its Gravitative Loads.
As shown in Figure 6, Figure 7, when water sampler is floated downward, and after making the 3rd connecting rope 31 exceptionally straight, the weight of water sampler
Power will overcome the elastic force of the second compression spring, make pushing piston drive unblock lever 318 up move, until pushing piston against
On the second collar stop 322；The end for now unlocking lever 318 is located at the outside of annular lug end face, and the 3rd sealing
Circle 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 annular lug of the 3rd compression spring 37 is toward collection
The other end passage of cylinder, and make annular lug be resisted against the end of collection tube；In this process intake chamber will be through following shape
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 6）；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.
As shown in figure 5, the present invention can lead to the 3rd connecting rope 31 of the second connecting rope 41 of control and each water sampler
Length controlling the spacing between collection tube and seabed, so as to water convenient, accurately in the specific range of collection seabed top
Sample.For example, the length of the second connecting rope is 10 meters, and the 3rd connecting rope length is 5 meters, then the spacing between collection tube and seabed is
5 meters.
5th, after completing water sampling, operator can be by fuse drawstring 62 toward pull-up（Reserve the upper end of fuse drawstring
On hull above the water surface）, grafting lever 63 is pulled out；So as to sedimentation counterweight be discharged；After counterweight release is settled, seabed
Water sampling equipment will under buoyancy automatic top.
