Problems solved by technology

Research on deep-sea hydrothermal sampling technology has been carried out at home and abroad, but most of the existing samplers can only collect a single sample, which cannot reflect the change of hydrothermal fluid over time, and some samplers that can collect multiple samples at a time are due to Pumps are used to extract hydrothermal fluid, the system consumes a lot of power, and it is difficult to realize long-term deployment on the seabed

Abstract

This invention relates to a deep sea hydrothermal fluid sequential sampling device. The invention includes one control unit and multi- sampling units. Control unit mostly includes electromagnetic coupling loop, circuit cavity and temperature probe. Each sampling unit includes one sampling valve and one sampling pip; sampling valve feed liquor mouth connect with sampling tube; out mouth connect with sampling pip; and through water tight wire connect with circuit cavity. Sampling pip composed by sampling cavity and accumulation cavity, could keep sample pressure, and carry out sample's equipressure transferring. The sampling pip adopt single time driven mechanism, can greatly depress systemic power consumption, and make sequential sampling implement have long-term disposal ability. Each sampling unit of sequential sampling implement is mutual independence, can at will to deploy, greatly advance sampler's reliability and applicability.

Description

technical field [0001] The invention relates to a deep sea water sampling device, in particular to a deep sea hydrothermal sequence sampling device capable of collecting multiple samples. Background technique [0002] Deep-sea hydrothermal vents are one of the most prominent features of the seabed. Not only are there a large number of mineral resources such as metal sulfides in the vicinity of hydrothermal vents, but also a unique biological community in an extreme environment has been bred, which has important deep-sea resource exploration and scientific research value. . Research on deep-sea hydrothermal sampling technology has been carried out at home and abroad, but most of the existing samplers can only collect a single sample, which cannot reflect the change of hydrothermal fluid over time, and some samplers that can collect multiple samples at a time are due to Pumps are used to extract hydrothermal fluid, and the power consumption of the system is relatively large, ...
