As shown in Figure 2 and Figure 3, tripper includes being arranged on collection tube lateral surface middle part, and the solution perpendicular with collection tube Lock cylinder body 313, the pushing piston 315 being slidably arranged in unblock cylinder body, is arranged on the unblock lever 318 of pushing piston one end And it is arranged on the piston rod 314 of the pushing piston other end.Unblock lever is located at the same side of pushing piston with collection tube.Unblock cylinder In vivo side is provided with the collar stop 322 of first annular block 321 and second.First annular block is located at passage with unblock lever The same side of piston.Pushing piston is located between first annular block and the second collar stop.It is provided with unblock cylinder side wall and leads Gas passage 323.The Single port of the air guide channel is connected with unblock inner chamber of cylinder block, and the port and the pushing piston of air guide channel Positioned at the opposite sides of the second collar stop.The another port of air guide channel and collection tube intracavity inter-connection.Unblock cylinder body outside Radial direction through hole 316 is provided with face, between collection tube and first annular block.Collection tube lateral surface is provided with and unblock cylinder body Coaxial axially extending bore.The cross-sectional area of unblock lever is identical with the cross-sectional area of piston rod, and the cross-sectional area of pushing piston To unlock the twice of the cross-sectional area of lever.

Unblock lever is coaxially disposed with unblock cylinder body.The end of unblock lever is through collection tube side wall, in collection tube Intracavity, specifically, unblock lever is through axially extending bore, in collection tube inner chamber.Set between axially extending bore and unblock lever There is the second sealing ring 317.Axially extending bore medial surface is provided with sealing ring installation, the and sealing ring is arranged on axially extending bore medial surface On sealing ring mounting groove in.When pushing piston is resisted against on first annular block, the end for unlocking lever stretches to annular The inner side of the end face of projection(As shown in Figure 2);When pushing piston is resisted against on the second collar stop, the end position of lever is unlocked In the outside of the end face of annular lug(As shown in Figure 4).

Piston rod is through unblock cylinder ends, positioned at unblock cylinder body outside.The 3rd is provided between piston rod and unblock cylinder body Sealing ring 319.Upper cover of piston rod is provided with the second compression spring 320 that pushing piston can be made to elapse toward collection tube direction.Second pressure Contracting spring can be such that pushing piston is resisted against on collar stop.One end of 3rd connecting rope with triggering cylinder body be connected, the other end with The end of piston rod is connected;In the present embodiment, the annular brace base plate of one end of the 3rd connecting rope and close vertical wire winding pole 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.
