Embodiment 1

[0039] Such as figure 1 The shown multi-point in-situ long-term observation system on the seabed includes platform frame 11, floating body material 6, underwater acoustic communication machine 5, beacon machine 1, monitoring cabin 2, control cabin 7, release control cabin 8, and central turret 10. Counterweight 9 and microelectrode detection 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.

[0040] 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 platform frame 11.

[0041] The second layer is equipped with monitoring cabin 2, control cabin 7 and...

Embodiment 2

[0053] Different from Embodiment 1, the microelectrode detection system 3 includes a base 23 and a static penetration probe 25 and eight microelectrodes 24 arranged on the base 23, and the static penetration probe 25 is arranged on the base 23. In the center, eight microelectrodes 24 are evenly arranged around the static penetration probe 25, and the length of the static penetration probe 25 is 5 cm longer than the length of the microelectrode 24, such as Figure 3-4 shown.

[0054] 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 control system completes the data collection of the static penetration probe 25 and the eight microelectrodes 24 .

[0055] Before the microelectrode detection system 3 is assembled, repeated destructive experiments are carried out on each microelectrode mold to obtain the ultimate destruct...

Abstract

The present invention relates to a long-term seabed-based multi-point in-situ observation system which comprises a platform frame, a buoyant material, an underwater acoustic communication device, a beacon, a monitoring chamber, a control chamber, a release control chamber, a central revolving table, ballasting weights and a microelectrode probing system; the platform frame has a cylindrical main body with a total of four layers from the top down; the buoyant material, the underwater acoustic communication device and the beacon are installed on the first layer; the monitoring chamber, the control chamber and the release control chamber are installed on the second layer; the central revolving table is installed on the third layer; and the ballasting weights are installed on the fourth layer. The present invention effectively realizes accurate multi-point locating function, then obtain the data of multiple detecting points in a detected zone upon demands, and finally can analyze and obtain the space distribution information of an active diffusion field. Therefore, important data supports are given to the evaluation on the oceanic environment effects in the process of petroleum leak and hydrate decomposition, thus providing support and services for the implementation of major projects such as seabed petroleum exploitation, and trial exploitation of the natural gas hydrates.

Description

technical field [0001] The invention relates to a seabed-based multi-point in-situ long-term observation 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 other by-products, which may seriously affect the stability of seabed, 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 evaluation of...
