The buoyancy of buoyant device is more than four water samplers, triggering device and triggers the gravity sum of counterweight, and is less than
Four gravity sums of water sampler, triggering device and sedimentation counterweight.When water sampler sinks under its Gravitative Loads, and
After making the rope of the 3rd connection 31 exceptionally straight, the gravity of water sampler will overcome the elastic force of the second compression spring, drive pushing piston
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 4, Figure 5）.
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 hanging type water sample air-tight sampling instrument in deep-sea of the invention is as follows：
First, as shown in figure 1, the spacing ball 32 of each water sampler is put into triggering cylinder body by the upper port of triggering cylinder body
It is interior；Then, upper piston body push-in is triggered in cylinder body, for stopping spacing ball, it is to avoid spacing ball is taken off by triggering cylinder body upper port
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 2 and Figure 3, the compression spring 37 of annular lug 38 and the 3rd is moved to 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 seawater cannot be introduced into collection tube.
Second, as shown in figure 1, deep-sea hanging type water sample air-tight sampling instrument is hung on ship edge by winch 5.When deep-sea is outstanding
The formula water sample air-tight sampling instrument that hangs down is hung in ship after by pull rope, and auxiliary stopper lever 15 is taken out by limiting through hole.
After pull rope hangs on ship edge deep-sea hanging type water sample air-tight sampling instrument, triggering counterweight makes lower piston body down
Move and be 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, it is to avoid spacing ball is deviate from by triggering cylinder body upper port.
3rd, water acquisition is carried out in the waters specified by being placed under the hanging type water sample air-tight sampling instrument of deep-sea；When deep-sea pendency
In decentralization process in waters, each water sampler will be suspended on formula water sample air-tight sampling instrument by spacing ball and the 4th connecting rope
In waters.
4th, as shown in figure 4, after deep-sea hanging type water sample air-tight sampling instrument sinks to seabed, triggering counterweight will first
Contacted with seabed, then deep-sea hanging type water sample air-tight sampling instrument continues to sink in the case where counterweight effect is settled, until sedimentation counterweight
Untill sinking to seabed；And in this process, the first compression spring 18 will promote upper and lower piston body up to promote, until under
Untill piston 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 more than spacing ball between the upper surface of upper piston body and triggering cylinder body；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 5, Figure 6, 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；Now the end of unblock 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 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 5）；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 4, the present invention can lead to the 3rd connecting rope 31 of the second connecting rope 41 of control and each water sampler
Length controls the spacing between collection tube and seabed, so that water convenient, accurately in the specific range of collection seabed top
Sample.For example, the length of the second connecting rope is 10 meters, the 3rd connecting rope length is 5 meters, then the spacing between collection tube and seabed is
5 meters.
