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 bottom water stratification water sampling device of the present invention is as follows:
The first, as shown in Figure 1, by traction rope 9, bottom water stratification water sampling device is sling; The bottom of traction rope is provided with two sections of transition connection cords, and transition connection cord is connected with suspension ring 81 Ei.
The second, seal plug is taken off, the spacing ball 32 of each water sampler is put into vertical cylinder body by the upper end open of vertical cylinder body, and make the 4th connection cord 33 be placed in corresponding threading breach 16; Then, by flat clamp toward pressing down, and flat clamp is made to be resisted against on vertical cylinder upper end face; The opening of each threading breach envelope hides by flat clamp; Again then, then seal plug is reinstalled in exhaust hole, shutoff exhaust hole; Now, water sampler will be hung between vertical cylinder body and flat clamp by spacing ball and the 4th connection cord.
3rd, as shown in Figure 4, Figure 5, 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.
4th, undertaken adopting water by placing under bottom water stratification water sampling device in the waters of specifying; When seabed water sampling system is in waters in decentralization process, each water sampler will be suspended in waters by spacing ball and the 4th connection cord; As shown in Figure 1.
5th, as shown in Figure 6, after bottom water stratification water sampling device sinks to seabed, releasing means and flip flop equipment will be suspended in above sedimentation counterweight by the first connection cord 5; And be positioned at below sedimentation counterweight 7 owing to triggering counterweight 22, trigger counterweight by first seabed interaction; Thus when after sedimentation counterweight seabed interaction, upper and lower piston body up promotes by the first Compress Spring 210, until upper piston body is resisted against on upper limit projection, thus makes third through-hole be positioned at below lower piston body, and making the first through hole, the second through hole and third through-hole are interconnected; Now, the hydraulic pressure of extraneous seawater will by third through-hole, the second through hole, and connecting pipe and the first through hole are applied on lifting piston 12, thus makes lifting piston moves, till being resisted against on positive stop.
When lifting piston is resisted against on positive stop, flat clamp and the spacing vertically between cylinder upper end face are greater than the diameter (spacing ball can be deviate between cylinder body upper end by flat clamp and vertically) of spacing ball; Thus now, each water sampler at the effect float downward of floatage body, as shown in Figure 6.
As shown in Figure 7, Figure 8, when water sampler floats, and after making the 3rd connection cord 31 exceptionally straight, the buoyancy of floatage body will overcome the elastic force of the second Compress Spring 320, pushing piston is made to drive unblock lever 318 to move down, till 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 7) 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.
The present invention can lead to the length of control the 3rd connection cord 31, controls the spacing between collection tube and seabed, thus gathers the water sample above seabed in specific range conveniently, accurately.
6th, after completing water sampling, grafting lever 63 by stay cord 61 toward pull-up (upper end of stay cord is reserved in above the water surface), can pull out by operator; Thus sedimentation counterweight is discharged; When after the release of sedimentation counterweight, bottom water stratification water sampling device will under buoyancy automatically above.
Bottom water stratification water sampling device of the present invention is equally applicable to apply in other waters.
