Deep-sea trace element automatic bottle opening clean water sampler device

Abstract

The invention belongs to the field of deep-sea detection and trace element collection, and particularly relates to a deep-sea trace element automatic bottle opening clean water sampler device. A water sampling bottle fixing frame is mounted on a water sampler base, and a balance base detachably mounted on the water sampler base is arranged below the water sampling bottle fixing frame; a clamping groove is formed in a water sampling bottle fixing frame through a clamping groove fixing plate, a water sampler hanging plate is detachably connected to the clamping groove, a plurality of CTD water sampling bottles are evenly arranged on the periphery of the clamping groove in the circumferential direction, each CTD water sampling bottle is hung on the water sampling bottle fixing frame, a hydraulic cylinder is installed on a bottle body of each CTD water sampling bottle, and the output end of the hydraulic cylinder is connected with a bottle cap of the CTD water sampling bottle through a traction spring. The device can collect deep-sea clean seawater, prevents the collected deep-sea seawater from being contaminated by other elements in the collection process, is convenient to install, simple to operate and high in working efficiency, and has important significance on deep-sea trace element collection and related research in China.

Description

technical field [0001] The invention belongs to the field of deep-sea detection and trace element collection, in particular to a deep-sea trace element automatic bottle-opening clean water collection device. Background technique [0002] Trace elements and their isotopes play a vital role in the study of marine biogeochemistry. Some trace elements (such as Fe, Cu, Co, etc.) participate in the biogeochemical cycle process as micronutrient elements, and profoundly affect the global carbon and nitrogen cycles. A growing body of research has shown that primary production in oceanic high-nutrient-low-chlorophyll (HNLC) regions is limited by micronutrients such as Fe. Martin proposed the famous iron hypothesis, that is, applying a small amount of iron to the ocean can trigger the blooming of phytoplankton and the reduction of CO 2 uptake, improve the efficiency of biological pumps and increase carbon sinks (Martin and Fitzwater, 1988). In response to the iron hypothesis, scient...
