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 triggering floating type water sampling device of the present invention 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, and the 4th connection cord 33 of correspondence is placed in threading breach 15.
As shown in Figure 2 and Figure 3, 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 traction rope 23, triggering floating type water sampling device is sling; The bottom of traction rope is provided with two sections of transition connection cords, and the suspension ring 22 of two transition connection cords respectively on suspension rod vertical with are connected.
After triggering floating type water sampling device is sling by traction rope 23, 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 triggering floating type water sampling device in the waters of specifying; When triggering floating type water sampling device 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 4, after triggering floating type water sampling device sinks to seabed, triggering counterweight will first seabed interaction, then triggers floating type water sampling device and under the effect of sedimentation counterweight, continues sinking, till sedimentation counterweight sinks to seabed; 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 thus now, each water sampler is at the effect float downward of floatage body.
As shown in Figure 5, Figure 6, 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 5) 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.
