Elastic force, make pushing piston drive unblock lever 318 to move down, until pushing piston is resisted against on the second collar stop 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 annular lug is resisted against the end of collection tube under the effect of the 3rd compression spring, intake chamber is located on the outside of collection tube.
The specific work process of the seabed water sampling equipment of the present 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, and corresponding 4th connecting rope 33 is placed in threading breach 15.
As shown in Figure 3, Figure 4, annular lug 38 and the 3rd compression spring 37 are moved to the same side of unblock lever, and are made
Annular lug is resisted against on unblock lever；Now, 310 intake chambers are located on the inside of collection tube, and extraneous sea water cannot be introduced into collection tube.
Second, as shown in figure 1, seabed water sampling equipment is sling by pull rope 23；The bottom of pull rope is provided with two
Section transition connecting rope, two transition connecting ropes are connected with the suspension ring 22 on a vertical suspension rod respectively.
After seabed water sampling equipment is sling by pull rope 23, triggering counterweight make lower piston body move down, and 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 by trigger cylinder body upper port abjection.
3rd, water acquisition is carried out by placing under seabed water sampling equipment in the waters specified；When seabed water sampling equipment
In decentralization process in waters, each water sampler will be suspended in waters by spacing ball and the 4th connecting rope.
4th, as shown in figure 5, after seabed water sampling equipment sinks to seabed, triggering counterweight will be connect with seabed first
Touch, then water sampling equipment in seabed under sedimentation counterweight effect continues to sink, till sedimentation counterweight sinks to seabed；And
In this process, the first compression spring 18 will promote upper and lower piston body up to promote, until lower piston body is resisted against upper limit
Till 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 6, Figure 7, 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, 37 annular lug of the 3rd compression spring is toward collection
The other end passage of cylinder, and make annular lug be resisted against the end of collection tube；Intake chamber will be through following shape in this process
State：One end of intake chamber 310 is located on the outside of collection tube, and the other end is located on the inside of collection tube（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 complete water sampling.
The present invention can lead to the length of the 3rd connecting rope 31 of control, control the spacing between collection tube and seabed, so as to
Water sample above convenient, accurate collection seabed in specific range.
5th, after completing water sampling, operator can be by fuse drawstring 62 toward pull-up（Reserve the upper end of fuse drawstring
On the hull above the water surface）, grafting lever 63 is pulled out；So as to sedimentation counterweight is discharged；After counterweight release is settled, seabed
Water sampling equipment will under buoyancy automatic top.
