[0048] When the sediment is sealed inside the sample positioning main barrel 4, the controller 103 controls the mover 901 and the auxiliary mover 904 to work together, thereby driving the moving rod 9 and the auxiliary moving rod 903 to cooperate and extend, thereby driving the sampling tube moving rod 906 to move arbitrarily, and further the controller 103 controls the multiple sampling tube clamping cameras 911 to start working, thereby monitoring the specific position of the sampling tube clamping plate 909. Further, when the multiple sampling tube clamping cameras 911 monitor that the sampling tube clamping plate 909 moves to the top of the sampling mechanism 7 where the clamping plate 8 is clamped, the controller 103 controls the sampling tube mover 907 to work, thereby driving the sampling tube moving rod 906 to extend, thereby driving the sampling tube clamping positioning rod 908 to move downward, thereby The sampling tube clamping plate 909 is driven to move downward. When the top of the sampling tube clamping plate 909 is in close contact with the sampling tube moving ring 701, the controller 103 controls the multiple sampling tube clamps 912 to work, thereby driving the multiple sampling tube clamping rods 910 to contract, thereby driving the multiple sampling tube clamping plates 909 to move toward the inside of the sampling mechanism 7, thereby clamping the sampling tube moving ring 701, thereby achieving the purpose of clamping the sampling mechanism 7. The controller 103 further controls a group of clamping rod rotation motors 802 here to work, thereby driving the clamping plate 8 to rotate, thereby disengaging the clamping plate 8 from the sampling tube positioning ring 702. The controller 103 further controls the mover 901 and the auxiliary mover 904 to cooperate, thereby moving the sampling mechanism 7 to the top of the sealing tube 6. The controller 103 further controls the sampling tube mover 907 to work again, thereby driving the sampling mechanism 7 to continue to move downward. When the sealing plate 601 is opened, the controller 103 controls the sampling tube mover 907 to continue working, thereby causing the sampling mechanism 7 to continue to move downward. When the positioning barrel camera 406 detects that the sampling mechanism 7 is slightly lower than the sealing tube 6, the controller 103 controls the sampling tube mover 907 to stop working. The controller 103 further controls the sampling rod controller 706 to work, thereby driving the sampling moving rod 710 to extend and retract, thereby changing the capacity of the sampler 709.

When the sampler 709 is full of samples, the controller 103 controls the sampler sealing plate rotating motor 714 to reverse again, so that the sampler sealing plate 712 and the filter plate 713 return to their original positions. At this time, due to the structure of the filter plate anti-rotation plate 724 and its top spring, the filter plate 713 can be reversed.Furthermore, at this time, since the sealing ring of the sampler sealing plate 712 and the filter plate 713 can prevent the sample from falling from the inside of the sampler 709, the controller 103 further controls the sampling tube mover 907 to work in reverse.

When the sampling is completed, the controller 103 controls the entire device to return to the water surface. The staff further recovers the equipment and takes out the sampling mechanism 7 that has completed the sampling. At this time, if the staff needs to study the sediment containing seawater, the controller 103 controls the sampler sealing plate to rotate the motor. The motor 714 rotates in reverse, thereby driving the sampler sealing plate 712 and the filter plate 713 to open at the same time. If a single sediment is needed, the controller 103 controls the sampler sealing plate rotating motor 714 to rotate forward, thereby driving the sampler sealing plate rotating motor 714 to rotate forward, thereby driving the sampler sealing plate 712 to rotate forward. At this time, due to the effects of the filter plate rotating block 719, the filter plate rotating head 722, and the filter plate anti-rotation plate 724, the filter plate 713 can be prevented from rotating, thereby ensuring that the seawater flows out while ensuring that the sediment does not fall. The controller 103 further controls the sampler sealing plate rotating motor 714 to continue to rotate forward and return to its original position. The controller 103 further controls the sampler sealing plate rotating motor 714 to reverse, thereby causing the sampler sealing plate 712 and the filter plate 713 to reverse, thereby causing the sampler 709 to open, so that a single sediment can be obtained.

When the resuspended sediment reaches the inside of the sample positioning main barrel 4, the controller 103 controls the positioning barrel rotation motor 404 to work, thereby driving the positioning sub-barrel 401 to rotate, so that the positioning sub-barrel 401 and the sample positioning main barrel 4 are sealed, thereby ensuring that the sediment does not move with the seawater during sampling, thereby ensuring the sampling accuracy and the sampling effect. When the sediment is sealed to the inside of the sample positioning main barrel 4, the controller 103 controls the mover 901 and the sub-move 904 to work together, thereby driving the moving rod 9 and the sub-moving rod 903 to cooperate in extension and retraction, thereby driving the sampling tube to move. The movable rod 906 can be moved arbitrarily, and the controller 103 further controls the multiple sampling tube clamping cameras 911 to start working, so as to monitor the specific position of the sampling tube clamping plate 909. Furthermore, when the multiple sampling tube clamping cameras 911 monitor that the sampling tube clamping plate 909 moves to the top of the sampling mechanism 7 where the clamping plate 8 is clamped, the controller 103 controls the sampling tube mover 907 to work, thereby driving the sampling tube moving rod 906 to extend, and then driving the sampling tube clamping positioning rod 908 to move downward, thereby driving the sampling tube clamping plate 909 to move downward.

At this time, due to the action of the sampling tube sealing ring 703 and the sealing ring 604, the sampling mechanism 7 and the sealing tube 6 can be tightly fitted. Further, the controller 103 controls the sampling tube mover 907 to continue working, thereby causing the sampling mechanism 7 to continue to move downward. When the positioning barrel camera 406 detects that the sampling mechanism 7 is slightly lower than the sealing tube 6, the controller 103 controls the sampling tube mover 907 to stop working. Further, the controller 103 controls the sampling rod controller 706 to work, thereby driving the sampling moving rod 710 to extend and retract, thereby changing the capacity of the sampler 709. Further, the controller 103 controls the sampler sealing plate rotation motor 714 to reverse, thereby driving the sampler sealing plate to be fixed. The positioning block 721 is reversed, thereby driving the sampler sealing plate 712 to reverse, and at the same time driving the positioning plate 715 to reverse, thereby driving the filter plate rotating block 719 to reverse, thereby driving the filter plate rotating head 722 to reverse, and then driving the filter plate positioning block 720 to reverse, thereby driving the filter plate 713 to reverse, thereby opening multiple samplers 709, thereby allowing resuspended sediment and seawater to enter the sampler 709. At this time, multiple samplers 709 can be compared. When the sampler 709 is full of samples, the controller 103 controls the sampler sealing plate rotating motor 714 to reverse again, thereby returning the sampler sealing plate 712 and the filter plate 713 to their original positions. At this time, due to the structure of the filter plate anti-rotation plate 724 and its top spring, it can be ensured The filter plate 713 can be reversed. At this time, the sealing ring of the sampler sealing plate 712 and the filter plate 713 can prevent the sample from falling from the inside of the sampler 709.
