Static sounding composite type geochemical microelectrode probe system

Abstract

The invention relates to a static sounding composite type geochemical microelectrode probe system. The static sounding composite type geochemical microelectrode probe system comprises a base, a static penetration probe and at least one microelectrode, wherein the static penetration probe and the microelectrodes are arranged on the base; the static penetration probe is arranged at the center of the base; the microelectrodes are distributed around the static penetration probe; the length of a conical tip of each static penetration probe is 4 to 8cm more than the length of a conical tip of the microelectrode. The static sounding composite type geochemical microelectrode probe system has the advantages that the static penetration probe is combined with the microelectrodes, and the static penetration threshold value is set according to the extreme breaking strength of the microelectrode, so as to ensure that the microelectrode stops penetrating into a precipitate before reaching the extreme breaking strength, and avoid the damage to the microelectrode; the penetrating depth of the microelectrode is larger; the microelectrode probe system can be applied into a seabed base multi-point in-situ long-term observing system; the multi-point accurate positioning function is effectively realized, the data of multiple detection points in the detection area can be obtained according to requirements, and the space distribution information of an active diffusion field is obtained after analysis.

Description

technical field [0001] The invention relates to a static detection composite geochemical microelectrode probe system, which belongs to the technical field of ocean observation. Background technique [0002] Marine resources are an important part of national marine rights and interests, and competition for resources such as deep-sea oil and gas hydrate has become the focus of international energy. During the exploitation of seabed natural gas hydrate, due to factors such as temperature, pressure, and external disturbances, the hydrate spontaneously decomposes, producing such as CH 4 、H 2 、H 2 S, O 2 And many other by-products, which may cause serious impact on seabed stability, marine engineering infrastructure, marine and atmospheric environment. Therefore, effective and comprehensive long-term monitoring of the natural gas hydrate exploitation process plays an important role in promoting the exploration and exploitation of hydrate resources and the investigation and eva...

Problems solved by technology

However, the vast majority of microelectrode probes are used to detect the chemical index content of seawater or loose sediments. Even the gel resin probe with the highest structural strength can only detect seabed sediments with relatively low physical and mechanical strength. limited detection

[0006] Obviously, if the microelectrode probe group is directly used to detect various chemical indicators during the process of penetrating the sediment, it is very easy to cause destructive damage to the microelectrode probe, resulting in the failure of long-term observation
