Visible double-row columnar sampler for deep-sea sampling

Abstract

The invention discloses a visible double-row columnar sampler for deep-sea sampling, and relates to the technical field of deep-sea sediment sampling. The sampler comprises a grounding balancer, wherein a visible grounding self-controlled sampling switch assembly is hung at the left end of the grounding balancer; two sets of vertically arranged columnar sampler main bodies are hung at the right end of the grounding balancer; a release connection assembly and a coaxial armored cable are connected with the top of the grounding balancer; the visible grounding self-controlled sampling switch assembly comprises a visible grounding hammer and a grounding hammer connection cable; an underwater camera is mounted in the visible grounding hammer, and connected with the lower end of the cable core of the grounding hammer connection cable; the upper end of the cable core of the grounding hammer connection cable is connected with the cable core of the coaxial armored cable. According to the sampler, visible target sampling can be realized, effective utilization of the sampler in a complex undersea environment, and the sampling success rate is improved; meanwhile, the number of samples obtained in a one-time sampling process is large, the sampling efficiency is high, and the modern oceanographic research demand is met.

Description

technical field [0001] The invention relates to the technical field of deep-sea sediment sampling, in particular to a visual double columnar sampler for deep-sea sampling. Background technique [0002] The column sampler is an important equipment for obtaining seabed sediment samples. The long columnar seabed sediment samples obtained by the columnar sampler are widely used in marine resource exploration fields such as marine oil and gas exploration, marine mineral resource exploration, marine environmental investigation and monitoring, etc. Made important contributions to national defense construction. [0003] At present, in ocean engineering construction and marine scientific research both at home and abroad, long columnar samplers composed of heavy hammer mechanism, sampling cylinder, hanging frame and other components are all used. In actual use, the long columnar sampler uses the gravity impulse of the weight mechanism to freely fall and insert into the sediment, the...
