Abstract

The invention relates to fidelity secondary sampling equipment for bottom sediments. The fidelity secondary sampling equipment comprises an upper barrel assembly and a lower barrel assembly, a piston assembly, a turning cover assembly, a middle supporting plate, an upper guide rail barrel, a lower guide rail barrel and a sampling barrel, wherein the middle supporting plate is mounted between the upper barrel assembly and the lower barrel assembly; the upper guide rail barrel is mounted between the middle supporting plate and an upper end sealing disc; the turning cover assembly and the piston assembly are mounted in the lower barrel assembly; and the sampling barrel is mounted at the lower end of the piston assembly. According to the fidelity secondary sampling equipment disclose4d by the invention, a designed mandrel and a designed elastic clamping plate structure can stop the sampling barrel from moving upwards in the sampling process; an overlying water check valve can guarantee that overlying water can be smoothly discharged out in the sampling process, and the low-disturbance sampling is realized; a designed secondary sampling check valve can be used for the secondary sampling so that the sampling rate is improved and the sampling cost is saved; and a sealing piece between two adjacent parts and a sampling back turning cover are automatically closed to guarantee the sealing of a system. The fidelity secondary sampling equipment disclosed by the invention is compact in structure, high in sampling rate and good in high-fidelity effect, the sampling time is saved and the cost is low; and the fidelity secondary sampling equipment is applicable to fidelity sampling of the bottom sediments, natural gas hydrates and mud samples in rivers and lakes.

Description

technical field [0001] The invention relates to a seabed sediment sampling device, in particular to a seabed sediment fidelity secondary sampling device. Background technique [0002] Seabed sediment sampling equipment is a kind of exploration equipment used to collect seabed surface sediments. The collected sediment samples can be used for geological science and biological science research. [0003] Seabed sediment sampling equipment is mainly used for: [0004] ①Exploration of seabed mineral resources, including searching for oil and seabed new energy - natural gas hydrate, etc.; [0005] ② Acquisition of biological samples; [0006] ③ Marine engineering geological survey, including coastal engineering survey, waterway survey, submarine tunnel geological survey, submarine cable, optical cable, gas pipeline, oil pipeline line survey, etc.; [0007] ④Global climate and environmental research, seabed sampling is also an important means to study climate and environmental ...
