Pressure-maintained transferring system for deep sea microbes

Abstract

The invention discloses a pressure-maintained transferring system for deep sea microbes. The pressure-maintained transferring system comprises a connection unit with a valve, a pressure-maintaining barrel communicated with the connection unit and a sampling unit installed in the pressure-maintaining barrel. The sampling unit comprises: a sampling barrel, which is axially and movably installed and has an open end that may extend out from the pressure-maintaining barrel, penetrate the connection unit and then implement sampling; a piston, which is circumferentially fixed in the sampling barrel, capable of axial sliding and used for pushing a material in the sampling barrel out from the open end; a first driving mechanism, which comprises a first power supply, a screw rod and an axially slidable slide block in thread transmission with the screw rod; and a second driving mechanism, which comprises a second power supply, a sampling driving rod and an axially slidable sampling transfer rod in circumferential fixed connection with the sampling driving rod. According to the invention, parallel double-shaft driving arrangement is employed, so the interior structure of the pressure-maintaining barrel is simplified, the structure of the system is more compact, and manufacturing cost is reduced; and axial movement power is transmitted through thread transmission, so stability, reliability and high movement precision are realized.

Description

technical field [0001] The invention relates to the field of deep-sea exploration and research equipment, in particular to a pressure-holding transfer system for deep-sea microorganisms. Background technique [0002] Abroad, in the 1970s, Yayanos of the Scripps Institute of Oceanography in the United States took the lead in conducting research on deep-sea microbiology, designed high-pressure culture tanks, and isolated deep-sea piezobacteria for the first time in 1979. In 1990, Japan's Mitsubishi Heavy Industries and Sanyo Corporation spent huge sums of money to develop a high-temperature / high-pressure culture system for deep-sea microorganisms for the Japan Marine Science and Technology Center. Since the late 20th century, with the improvement of deep-sea technology capabilities, more and more countries have devoted themselves to the frontier of deep-sea research. At present, countries carrying out research on deep-sea microorganisms are mainly distributed in Europe, Ameri...

In comparison, this structure has already performed a sub-sampling when the push rod is used to push the sample, so the sample utilization rate is relatively low
