Long period detection system for in-situ temperature of deep-sea hydrothermal vent

Abstract

The invention relates to an original temperature detecting system of deep sea hot liquid injector, which comprises a cultivate cap, a base, a connecting chamber and a circuit chamber, wherein the system has multi-path thermal couples; the heads of multi-path thermal couples are laminated arranged inside the cultivate cap to form multilayer multi temperature detecting points; multi-path thermal couples are connected to the connecting chamber, via watertight connector to connect the circuit board of circuit chamber while the circuit board has multi-path temperature collecting, processing and storing functions, to transmit the detected temperature of detecting points of cultivate cap to the circuit board 16 of circuit chamber 4 to be processed and stored. The invention has high-pressure and high-temperature resistances and multi-path temperature collection function, to record the temperature change in mineralization process of seabed hot liquid, and collect the seabed mineral and biological samples.

Description

technical field [0001] The invention relates to a detection system capable of long-term detection of the ambient temperature of seabed hydrothermal vents. Background technique [0002] The scalding hot liquid with a temperature of more than 300 degrees Celsius is sprayed upward from the hydrothermal vents on the seabed. When it encounters icy seawater, it will be mineralized into chimney-shaped metal sulfide minerals up to 13 meters high. There are also a large number of clusters near the "chimney". Undersea creatures. If this process takes place in an artificial culture basket, and some characteristic parameters of this process are recorded in situ, then the submarine hydrothermal eruption and the unique life forms around it can be studied in depth, so as to provide human Provides an important window into the study of the origin of life and the deep biosphere. The traditional method of detecting the temperature of seafloor hydrothermal fluids is to use a deep submersible ...

AI Technical Summary

Problems solved by technology

The traditional method of detecting the temperature of seafloor hydrothermal fluids is to use a deep submersible to conduct a short-term test on the erupted hydrothermal fluid with a temperature measuring device in order to roughly know the eruption temperature of the vent. It cannot know the temperature of the hydrothermal fluid during the mineralization process. , it is especially difficult to conduct in-situ long-term detection of its temperature to establish the temperature field of the "chimney" sediment formed after hydrothermal mineralization, making it difficult to further study the mineralization mechanism of seabed hydrothermal
