It is connected, the other end is connected with the end of piston rod.
Gravity of the buoyancy of floatage body more than water sampler；The buoyancy of floatage body is more than water sampler in the present embodiment
More than the twice of gravity, and when water sampler floats, and after making the 3rd connecting rope exceptionally straight, the buoyancy of floatage body will overcome the
The elastic force of two compression springs, makes pushing piston drive unblock lever 318 to move down, until pushing piston to be resisted against second annular
On block 322；The end for now unlocking lever 318 is located at the outside of annular lug end face.
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.
A kind of specific work process of fixed point trigger-type bottom water fidelity harvester 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, and corresponding second connecting rope 33 is placed in threading breach 15.
As shown in Figure 2 and Figure 3, 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, sling trigger-type bottom water fidelity harvester is pinpointed by winch 5；And protect in fixed point trigger-type bottom water
Place under true harvester and carry out in the waters specified water acquisition；
When winch will pinpoint trigger-type bottom water fidelity harvester sling after, triggering counterweight make lower piston body move down,
And be resisted against on lower limit projection；Now upper piston body is located in the triggering cylinder body above upper limit projection, spacing for stopping
Ball, it is to avoid spacing ball by trigger cylinder body upper port abjection.
When trigger-type bottom water fidelity harvester is pinpointed in waters in decentralization process, each water sampler will be by spacing
Ball and the second connecting rope are suspended in waters.
3rd, as shown in figure 4, when fixed point trigger-type bottom water fidelity harvester sinks to seabed, triggering counterweight by head
First contact with seabed, till the lower end of support column is supported on seabed；And in this process, the first compression spring 18 will be pushed away
Move upper and lower piston body up to promote, till lower 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 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, thus now, each water sampler floats in the presence of floatage body.
As shown in Figure 5, Figure 6, 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
Till 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 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 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 4）；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 present invention can lead to the length of the 3rd connecting rope 31 of control controlling the spacing between collection tube and seabed, so as to
The convenient, water sample accurately gathered in the specific range of seabed top.
