[0030] It should be noted that when it is necessary to drive the spiral blade 8 to detach from the seabed surface, the third hydraulic telescopic rod 28 drives the movable ring 27 to move downward, reduces the length of the compression spring 30, increases the friction between the first damping disc 24 and the second damping disc 26, ensures that when the second damping disc 26 rotates in the opposite direction, the second damping disc 26 can drive the first damping disc 24 to rotate synchronously by friction, and then drives the second damping disc 26 to rotate in the opposite direction by the servo motor 25, so that the spiral blade 8 detaches from the seabed surface, the movable box 6 and the support part 38 move upward relative to the third guide column 39 and the base 1, and the fourth hydraulic telescopic rod 42 drives the support plate 41 to move upward, when the spiral blade 8 detaches When it is on the seabed surface, the support plate 41 supports the counterweight 9 to move continuously upward, and the counterweight 9 drives the movable box 6 and the support part 38 to move upward. Finally, the movable box 6 and the support part 38 move up to the initial height, and the support part 38 and the fixed plate 40 are in contact, completing the resetting of the position of the movable box 6 and the spiral blade 8.

[0031] When in use, first the base 1 and the hanger 2 are sunk to the bottom of the water by ropes, and then gravity is applied to the movable box 6 through the counterweight moving mechanism to move the movable box 6 downward, and the guide member is designed to make the movable box 6 move smoothly in the vertical direction, and the damping drive mechanism drives the first rotating shaft 7 and the spiral blade 8 to rotate, and the spiral blade 8 is screwed into the seabed surface to fix the base 1 and the hanger 2 relative to the seabed surface to avoid the base 1 and the hanger 2 shaking relative to the seabed surface during the sampling process, and then the first sampling bucket 3 and the second sampling bucket 4 are driven to move in different directions through the different moving structure, and the mud sample is grabbed by the first sampling bucket 3 and the second sampling bucket 4. After the sampling is completed, the damping drive mechanism drives the first rotating shaft 7 and the spiral blade 8 to rotate in the opposite direction, so that the spiral blade 8 is separated from the seabed surface, and the counterweight moving mechanism supports the movable box 6 to move up to the initial height, so that the movable box 6 is reset to the initial position relative to the base 1, and then the base 1 and the hanger 2 are lifted by the rope, and when the base 1 is separated from the seabed surface, the sealing frame 5 is driven to rotate by the rotator, so that the sealing frame 5 rotates to the junction of the first sampling bucket 3 and the second sampling bucket 4, and the junction of the first sampling bucket 3 and the second sampling bucket 4 is sealed to reduce the possibility of mud samples leaking from between the first sampling bucket 3 and the second sampling bucket 4; The first hydraulic telescopic rod 16 drives the first movable plate 15 to move, and the first movable plate 15 drives the two first toothed plates 14 to move.

The second rotating shaft 11 and the first rotating sleeve 12 can respectively drive the first sampling bucket 3 and the second sampling bucket 4 to rotate in opposite directions, and the first toothed plate 14 drives the guide block 17 to slide relative to the first guide column 18. The design of the guide block 17 and the first guide column 18 allows the first toothed plate 14 to slide smoothly relative to the fixed box 10. The second hydraulic telescopic rod 22 drives the second toothed plate 21 to move. The second toothed plate 21 drives the second rotating sleeve 19 to rotate relative to the fixed box 10 through the second gear 20. The second rotating sleeve 19 can drive the sealing frame 5 to rotate, so that the sealing frame 5 moves to the junction of the first sampling bucket 3 and the second sampling bucket 4; The movable ring 27 is driven to move downward relative to the movable seat 23 and the second guide column 29 by the third hydraulic telescopic rod 28, so as to change the distance between the movable ring 27 and the movable seat 23, thereby changing the deformation degree of the compression spring 30, controlling the thrust applied by the compression spring 30 to the movable seat 23 and the second damping disk 26, thereby controlling the friction between the first damping disk 24 and the second damping disk 26, and through the design of the third guide column 39, the support part 38 and the fixed plate 40, the movable box 6 can be smoothly moved in the vertical direction relative to the base 1, and the movable box 6 is driven by the fourth hydraulic telescopic rod 42. The support plate 41 moves downward, and the counterweight block 9 and the movable box 6 move downward synchronously due to their own gravity. The support portion 38 slides relative to the third guide column 39. When the spiral blade 8 contacts the seabed surface, the support plate 41 continues to move downward, and the support plate 41 no longer supports the counterweight block 9 and the movable box 6. The counterweight block 9 applies downward pressure to the movable box 6 and the spiral blade 8, and the second damping disk 26 is driven to rotate by the servo motor 25. The second damping disk 26 can drive the first damping disk 24 and the first rotating shaft 7 to rotate synchronously through friction, so that the spiral blade 8 rotates into the seabed surface. When it is necessary to drive the spiral blade 8 to separate from the seabed surface, the movable ring 27 is driven downward by the third hydraulic telescopic rod 28 to reduce the length of the compression spring 30 and increase the friction between the first damping disc 24 and the second damping disc 26 to ensure that when the second damping disc 26 rotates in the opposite direction, the second damping disc 26 can drive the first damping disc 24 to rotate synchronously by friction, and then the second damping disc 26 is driven in the opposite direction by the servo motor 25 to rotate, so that the spiral blade 8 separates from the seabed surface, the movable box 6 and the support part 38 move up relative to the third guide column 39 and the base 1, and the fourth hydraulic telescopic rod 42 drives the support plate 41 to move up. When the spiral blade 8 separates from the seabed surface, the support plate 41 supports the counterweight block 9 to continue to move up, and the counterweight block 9 drives the movable box 6 and the support part 38 to move up. Finally, the movable box 6 and the support part 38 move up to the initial height, and the support part 38 contacts the fixed plate 40 to complete the resetting of the movable box 6 and the spiral blade 8.
