Integrated multifunctional deep sea water body sampling probe

Abstract

The invention relates to an integrated multifunctional deep sea water body sampling probe, and belongs to the technical field of deep sea sampling. The sampling probe comprises an installing base anda detection sampling unit, wherein communication holes penetrating through the front and back end surfaces of the installing base, and a lateral connection hole penetrating from the side surface of the installing base to a position communicating with the communication holes are formed in the installing base; the detection sampling unit comprises a sampling pipe, a filtering head, a temperature detection sensor, a chemical parameter sampling sensor and a heat conduction protection sleeve; the filtering head is arranged on the inlet end of the sampling pipe in a sleeving way; the temperature detection sensor and the chemical parameter sampling sensor are arranged in the sampling pipe in a sleeving way; the heat conduction protection sleeve is arranged outside the temperature detection sensorin a watertight and sleeving way; the outlet end of the sampling pipe is arranged in the inlet end of the communication holes in a watertight and sleeved way; the outlet end of the heat conduction protection sleeve extends into the communication holes in a watertight way; a temperature signal wire extends out of the communication holes; a signal wire of the chemical parameter sampling sensor passes through the communication holes in a watertight way; and the water inlet end of a sample conveying pipe is connected in the outlet end of the lateral connection hole in a watertight and sleeved way. The sampling probe can be used for sequence sampling, and can be widely applied to the field of ocean exploration.

Description

technical field [0001] The invention relates to the technical field of deep sea sampling, in particular to a multifunctional deep sea water sampling probe integrated with a temperature sensor and a chemical sensor. Background technique [0002] Submarine hydrothermal activities play a very important role in regulating the heat exchange process between the interior of the earth and seawater, and obtaining hydrothermal samples is a necessary means for studying hydrothermal activities. Sampling probes are usually used to sample hydrothermal fluids. For example, a handheld deep-sea airtight isobaric hydrothermal sampler disclosed in the patent document with publication number CN1837770A is adopted, which includes a sampling unit, a temperature detection unit 19 and a storage unit 20 . [0003] Wherein, the sampling unit includes a sampling tube 1 and a sampling valve 2, the liquid outlet of the sampling tube 1 communicates with the liquid inlet of the storage unit 20 through a c...

AI Technical Summary

Problems solved by technology

After sampling, the chemical parameters of the obtained hydrothermal fluid are analyzed on land. Due to environmental changes such as temperature and the mixing of multiple sampling samples, the obtained chemical parameters are difficult to reflect the original parameter information, and it is difficult to achieve actual detection. required sequence sampling
