Abstract

The high-fidelity hand held deep sea hydrothermal fluid sampler includes control cavity, sampling barrel, energy accumulator and circuit cavity fixed into one integral. The control cavity is provided with water sucking tube, relieving port, axial spring, conic valve, control valve core and sampling triggering screw possessing one end exposed outside the cavity and wound ICL coil. The sampling barrel has piston and piston rod connected via non-return valve with the control cavity. The energy accumulator has one path communicated with sea water via the non-return valve and the other path communicated with the sampling barrel via the non-return valve and cut-off valve. The circuit cavity is provided with hydrothermal fluid probe for detecting the temperature of the fluid and circuit board with output connected to the ICL coil. The sampler has high strength, light weight, maximum sampling water depth of 7000, maximum holding pressure of 70 MPa and highest sampling temperature of 400 deg.c.

Description

technical field [0001] The invention relates to a hand-held deep-sea hydrothermal fidelity sampler, in particular to a device for realizing deep-sea hydrothermal fidelity sampling by adopting pressure self-compensation technology. Background technique [0002] At present, in the exploration of marine resources, the international marine community has carried out research on deep-sea hydrothermal sampling technology. However, the existing samplers at home and abroad do not keep heat or pressure, and the original composition and state of the collected hydrothermal samples have changed due to changes in temperature, pressure, light and other conditions, which cannot provide scientists with hydrothermal fluids. in situ information. Contents of the invention [0003] The object of the present invention is to provide a hand-held deep-sea hydrothermal fidelity sampler suitable for deep-sea hydrothermal collection. [0004] The ...
