Abstract

The invention discloses an automatic sampler of submarine hydrothermal solution, comprising an opened valve cavity, a sampling cavity, a temperature measuring circuit cavity, and a temperature displaying circuit cavity, which are arranged on a support. In the sampler of the invention, an electronic-controlled trigger mechanism arranged in the opened valve cavity is used for controlling the sampling valve to realize the automatic sampling. The sampler can measure and display the temperature of the hydrothermal solution in real time during the sampling process, thereby facilitating the finding of the optimal sampling point. The sampler has compact overall structure and small size, is suitable for the operation of a diver or a bathyscaphe manipulator, and can meet the requirement of hydrothermal solution sampling in the shallow sea and the deep sea.

Description

technical field

[0001] The invention relates to a seabed hydrothermal sampling device, in particular to a seabed hydrothermal automatic sampler which can measure and display the temperature of the hydrothermal liquid in real time. Background technique

[0002] Submarine hydrothermal activities play a very important role in regulating the exchange of materials and heat between seawater and the oceanic crust. In addition to the deep-sea hydrothermal vents widely distributed in mid-ocean ridges and back-arc basins, submarine hydrothermal vents also exist in large numbers in volcanoes. Shallow sea areas such as the undersea wing and the top of submarine volcanoes. Obtaining samples is a necessary means to study hydrothermal activities. At present, research on hydrothermal samplers has been carried out at home and abroad, but most hydrothermal samplers currently focus on deep-sea applications, and rely on deep submersibles for complex operations. It cannot be conveniently used f...
