Abstract

The invention discloses a deep sea water body sequence sampling device with a through-flow structure, and belongs to the technical field of deep sea water sampling equipment. The deep sea water body sequence sampling device comprises an outer frame, a plurality of water samplers independently arranged in the outer frame and a controller used for controlling the water sampling process, wherein eachwater sampler comprises a sampling cavity, an inlet ball valve and an outlet ball valve; the inlet ball valve and the outlet ball valve are arranged at the two ends of the sampling cavity respectively; the inlet ball valves of all the samplers are connected to sampling pipe nozzles through first pipelines; the outlet ball valves of all the samplers are connected to sampling pumps through second pipelines; and a first switch assembly for sequentially controlling the inlet ball valves of all the samplers and a second switch assembly for sequentially controlling the outlet ball valves of all thesamplers are arranged in the outer frame. The water samplers are mounted on the outer frame according to the number and types of samples needing to be sampled, the types of the water samplers can beset according to sampling requirements, and the whole device is carried on an ROV or a horn.

Description

technical field [0001] The invention relates to the technical field of deep sea water mining equipment, in particular to a deep sea water serial sampling device with a flow-through structure. Background technique [0002] In recent years, the exploration, research and development of the ocean have been paid more and more attention by researchers and countries. Deep-sea hydrothermal fluids, cold seeps, near-bottom water samples, and other deep-sea water samples have important research significance in the fields of geology, chemical engineering, medical treatment, and biology. One of the important means of research on these water body samples is sampling, that is, to obtain samples at the location of the samples, and take them back for analysis in the laboratory. Collecting deep seawater samples, measuring various physical and chemical indicators of deep seawater samples, and understanding their composition and state are very important in the environmental exploration of ocea...
