Piston rod is through unlocking cylinder ends, being positioned at outside unblock cylinder body.The 3rd O-ring seal 319 is provided with between piston rod and unblock cylinder body.Upper cover of piston rod is provided with second Compress Spring 320 that pushing piston can be made to pass toward collection tube direction.Second Compress Spring can make pushing piston be resisted against on collar stop.One end of 3rd connection cord is connected with triggering cylinder body, and the other end is connected with the end of piston rod; Specifically, one end of the 3rd connection cord is connected with the second link, and the other end is connected with the end of piston rod.
The buoyancy of buoyant device is greater than four water samplers, flip flop equipment and triggers the gravity sum of counterweight, and is less than the gravity sum of four water samplers, flip flop equipment and sedimentation counterweight.When water sampler sinks under its Gravitative Loads, and after making the 3rd connection 31 rope exceptionally straight, the gravity of water sampler will overcome the elastic force of the second Compress Spring, makes pushing piston drive unblock lever 318 up to move, until pushing piston is resisted against on the second collar stop 322; The end now unlocking lever 318 is positioned at the outside (as shown in Figure 5, Figure 6) of annular lug end face.
When annular lug and the 3rd Compress Spring move to the same side unlocking lever, described intake chamber is positioned at inside collection tube.When convex annular is resisted against the end of collection tube under the 3rd Compress Spring effect, intake chamber is positioned at outside collection tube.
The specific works process of seabed of the present invention water body spacing sampling equipment is as follows:
The first, as shown in Figure 1, the spacing ball 32 of each water sampler is put into by the upper port triggering cylinder body and triggers cylinder body; Then, upper piston body being pushed and triggers in cylinder body, for stopping spacing ball, avoiding spacing ball to deviate from by triggering cylinder body upper port; Again then, auxiliary stopper lever 15 is inserted in limiting through hole, for stopping that upper piston body shifts out outward;
As shown in Figure 3, Figure 4, annular lug 38 and the 3rd Compress Spring 37 are moved to the same side unlocking lever, and make annular lug be resisted against on unblock lever; Now, 310 intake chambers are positioned at inside collection tube, and extraneous seawater cannot enter collection tube.
The second, as shown in Figure 1, by winch 5, deep-sea hanging type water sample air-tight sampling instrument is hung on ship edge.When deep-sea hanging type water sample air-tight sampling instrument is hung behind ship edge by traction rope, auxiliary stopper lever 15 is taken out by limiting through hole.
When seabed water body spacing sampling equipment is hung behind ship edge by traction rope, trigger counterweight and lower piston body is moved down and is resisted against on lower limit projection; Now upper piston body is positioned at the triggering cylinder body above upper limit projection, for stopping spacing ball, avoids spacing ball to deviate from by triggering cylinder body upper port.
3rd, undertaken adopting water by placing under the water body spacing sampling equipment of seabed in the waters of specifying; When seabed water body spacing sampling equipment is in waters in decentralization process, each water sampler will be suspended in waters by spacing ball and the 4th connection cord.
4th, as shown in Figure 5, after seabed water body spacing sampling equipment sinks to seabed, trigger counterweight and incite somebody to action first seabed interaction, then seabed water body spacing sampling equipment continues to sink, till sedimentation counterweight sinks to seabed under the effect of sedimentation counterweight; And in this process, the first Compress Spring 18 will promote upper and lower piston body and up 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 positioned at the top of the upper surface of triggering cylinder body, and the spacing between upper piston body and the upper surface of triggering cylinder body is greater than the diameter of spacing ball; Spacing ball can be deviate from by triggering cylinder body upper port, and 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 connection cord 31 exceptionally straight, the gravity of water sampler will overcome the elastic force of the second Compress Spring, pushing piston is made to drive unblock lever 318 up to move, until pushing piston is resisted against on the second collar stop 322; The end now unlocking lever 318 is positioned at the outside of annular lug end face, and the 3rd O-ring seal 317 is still resisted against on unblock lever side.
When the end unlocking lever is positioned at the outer rear flank of annular lug end face, the 3rd Compress Spring 37 annular lug is passed toward the other end of collection tube, and makes annular lug be resisted against the end of collection tube; Intake chamber is by through following state in this process: one end of intake chamber 310 is positioned at outside collection tube, and the other end is positioned at (as shown in Figure 6) inside collection tube; Now, extraneous seawater 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 the second O-ring seal fitted seal.So far water sampling is completed.
As shown in Figure 5, the present invention can lead to the length of the 3rd connection cord 31 of control second connection cord 41 and each water sampler, controls the spacing between collection tube and seabed, thus gathers the water sample above seabed in specific range conveniently, accurately.Such as, the length of the second connection cord is 10 meters, and the 3rd connection cord length is 5 meters, then the spacing between collection tube and seabed is 5 meters.
5th, after completing water sampling, grafting lever 63 by fuse stay cord 62 toward pull-up (upper end of fuse stay cord is reserved on the hull above the water surface), can pull out by operator; Thus sedimentation counterweight is discharged; When after the release of sedimentation counterweight, seabed water sampling equipment will under buoyancy automatically above.
