MULTILAYER FIDELITY-MAINTAINING STORAGE SAMPLING APPARATUS FOR SUBMARINE SEDIMENT
Document Type and Number:
WIPO Patent Application WO/2020/258535
Kind Code:
A1
Abstract:
Disclosed is a multilayer fidelity-maintaining storage sampling apparatus for submarine sediment, the apparatus comprising a housing (1), wherein the interior of the housing (1) is fixedly connected to a sampling barrel (2); the sampling barrel (2) comprises a sealing plate (3); an air discharge passage (4) is provided in the center of the sealing plate (3); the lower part of the sealing plate (3) is fixedly connected to a fixed rod (5); a compression spring (6) sheathes the surface of the fixed rod (5); the end, away from the sealing plate (3), of the compression spring (6) is elastically connected to a storage chamber (7); the surface of the storage chamber (7) is fixedly connected to a sampling mechanism (8); the sampling mechanism (8) comprises a box (9); inclined plates (10) are movably connected to the interior of the box (9); the end, away from the box (9), of the inclined plate (10) is movably connected to a reset spring (11); the end, away from the inclined plate (10), of the reset spring (11) is movably connected to a rotary plate (12); the lower part of the rotary plate (12) is fixedly connected to a traction rope (13); the end, away from the rotary plate (12), of the traction rope (13) is fixedly connected to a connecting plate (14); and the lower part of the box (9) is movably connected to a drill bit (15). The apparatus can realize layered storage and extraction of sediment at different depths.
