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 on the outside of collection tube.
The specific work process of the trigger-type seabed water sampling system of the present invention is as follows：
First, as shown in figure 1, trigger-type seabed water sampling system is sling by pull rope 9；The bottom of pull rope sets
There are two sections of transition connecting ropes, transition connecting rope is connected with suspension ring 81.
Second, seal plug is removed, the spacing ball 32 of each water sampler is put into by the upper end open of vertical cylinder body
Vertically in cylinder body, and the 4th connecting rope 33 is made to be placed in corresponding threading breach 16；Then, flat clamp is pressed down, and is made
Flat clamp is resisted against on vertical cylinder upper end face；The opening envelope of each threading breach is hidden by flat clamp；Followed by, then by seal plug
It is reinstalled in exhaust hole, blocks exhaust hole；Now, water sampler will be hung by spacing ball and the 4th connecting rope
Between vertical cylinder body and flat clamp.
3rd, as shown in Figure 4, Figure 5, annular lug 38 and the 3rd compression spring 37 are moved to into the same of unblock lever
Side, and 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.
4th, water acquisition is carried out by placing under the water sampling system of trigger-type seabed in the waters specified；When seabed, water sample is adopted
In decentralization process in waters, each water sampler will be suspended in waters collecting system by spacing ball and the 4th connecting rope；Such as
Shown in Fig. 1.
5th, as shown in fig. 6, after trigger-type seabed water sampling system sinks to seabed, release device and triggering are filled
Put and will be suspended in above sedimentation counterweight by the first connecting rope 5；And it is located at below sedimentation counterweight 7 due to triggering counterweight 22, touches
It is transported to and first will contacts with seabed again；Thus after settling counterweight and contacting with seabed, the first compression spring 210 is by upper and lower piston body
Up promote, until upper piston body is resisted against on upper limit projection, so that third through-hole is located at below lower piston body, and make the
One through hole, the second through hole and third through-hole are interconnected；Now, the hydraulic pressure of extraneous sea water will be by third through-hole, the second through hole,
Connecting tube and first through hole are applied on lifting piston 12, so that move on lifting piston, until be resisted against on positive stop being
Only.
When lifting piston is resisted against on positive stop, the spacing between flat clamp and vertical cylinder upper end face is more than spacing
The diameter of ball（Spacing ball can be deviate from by between flat clamp and vertical cylinder body upper end）；Thus now, each water sampler is floating
Float in the presence of power body, as shown in Figure 6.
As shown in Figure 7, Figure 8, 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 7）；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.
6th, after completing water sampling, operator can be by drawstring 61 toward pull-up（The upper end of drawstring is reserved on the water surface
Side）, grafting lever 63 is pulled out；So as to sedimentation counterweight is discharged；After counterweight release is settled, trigger-type seabed water sampling system
System will under buoyancy automatic top.
The trigger-type seabed water sampling system of the present invention is applied in being equally applicable to other waters.
