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

Embodiment 1

[0043] like figure 1 The microelectrode probe system shown includes a base 23, a static penetrating probe 25 and eight microelectrodes 24 arranged on the base 23 (the number of microelectrodes can be selected according to the actual index to be detected, and this implementation Take eight as an example), the indexes detected by eight microelectrodes 24 are respectively CH 4 , O 2 , pH, Redox, H 2 、H 2 S, NO, NO 2 . The static penetration probe 25 is arranged in the center of the base 23, and eight microelectrodes 24 are evenly arranged around the static penetration probe 25. The distance between the static penetration probe 25 and each microelectrode 24 is 4 cm. The length of the probe head 25 is 5 cm longer than the length of the microelectrode 24 .

[0044] The static penetration probe 25 and the eight microelectrodes 24 are connected to the data acquisition unit respectively, and the data acquisition unit is connected to the general control system, and the general con...

Embodiment 2

[0048] The microelectrode probe system of embodiment 1 is applied to figure 2 In the multi-point in-situ long-term observation system based on the seabed, the observation system includes a platform frame 11, a floating body material 6, an underwater acoustic communication machine 5, a beacon machine 1, a monitoring cabin 2, a control cabin 7, a release control cabin 8, and a central rotary Stage 10, counterweight 9 and microelectrode probe system 3. The main body of the platform frame 11 is in the shape of a cylinder and has four layers from top to bottom.

[0049] The first layer installs the floating body material 6, the underwater acoustic communication machine 5, the beacon machine 1 and the suspension ring 4, wherein the floating body material 6 is designed to be divided into six equal parts for ease of installation, and is placed in the frame. The underwater acoustic communication machine 5 and the beacon machine 1 and suspension ring 4 are all arranged on the top of p...

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...
