Acoustic releaser (16) freely discharges feeler lever (4), makes it under the effect of gravity with certain initial velocity injection Sandy Seabed, counterweight cabin
(13) acceleration transducer in receives bottom out signal after, be transferred to primary processor, feeler lever (4) starts according to preset mode
Work;Second level perforation device enters state to be triggered;
2) after work starts, if occurring, bed ripples trough is gradually mobile to feeler lever (4), and injection cone (17) is passed through relative to bed ripples surface
Enter depth reduction, side friction also declines therewith, and feeler lever (4) generates downward sliding after penetration resistance drops to certain value, matches
After acceleration transducer in weight cabin (13) monitors displacement, second level perforation device is triggered, launches release (10) for guide pipe
(9) release downwards, and downward motive force is provided, guide pipe (9) is moved downward relative to feeler lever (4), at this time guide pad (22)
It is moved upwards under the action of compression spring (23), and enters an annular groove (21) on the outside of feeler lever (4), guide pad (22)
Lower end surface with annular groove (21) be the point of application push feeler lever (4) move downward;
After the acceleration transducer in feeler lever (4) counterweight cabin (13), which receives, bottoms out signal, it is transferred to primary processor, feeler lever 4
It is started to work according to preset mode;Third level perforation device enters state to be triggered;
3) triggering mode of third level injection system displacement trigger mechanism identical with second level perforation device is identical;
4) after in-situ observation end cycle, by support vessel (28) traveling to target point, is placed under cable under water nobody
Ship recycles observation device.
6. the method for multistage injection as claimed in claim 5, it is characterized in that also time trigger mechanism in the step 3),
I.e. after the completion of the injection of the second level, the body of rod does not generate displacement within the set time, no matter the then acceleration after reaching setting time
Whether sensor monitors that displacement all triggers third level perforation device, by feeler lever (4) further downward injection.
