Problems solved by technology

Although it can effectively prevent the growth and enrichment of submarine microorganisms on the surface of the equipment, it will dissolve some toxic heavy metals into the seawater after soaking in seawater for a long time. Once the coating is hit by an external force, it may crack and fall off, exposing the protected substrate. , the erosion of the equipment will accelerate
The patent "A Sacrificial Anode Protection Device for Seawater Pipelines" (CN2656433Y) discloses a sacrificial anode protection device for seawater pipelines. However, this device is suitable for tubular and columnar parts, has a small scope of application, and requires external copper wires. For complex ocean currents under the sea, there is a wire disconnection
It is necessary to replace the anode block underwater regularly. Every time it is replaced, the submarine pipeline on the surface of the protected equipment needs to be treated again. The installation steps are complicated and the underwater operation is difficult

Abstract

The invention provides a metal in-situ protection device and method based on deep-sea microorganisms and sediments, and belongs to the technical field of deep-sea metal protection. The device comprises at least one microbial catalytic decomposition reaction unit, a separation and sedimentation unit and a conducting and fixing device, wherein the microbial catalytic decomposition reaction units areconnected in parallel; the microbial catalytic decomposition reaction units are connected with the separation and sedimentation unit in parallel; the conducting and fixing device comprises an outer shell fixing part and a conducting part and is used for fixing the microbial catalytic decomposition reaction units and the separation and sedimentation unit and supplying power to the units. The metalin-situ protection device is installed on the two sides of a seabed traveling mechanism in parallel, and the bottom is inserted into the sediments; the metal in-situ protection device does not need external energy supply and is free of raw material loss; when advancing, the protection device completes the self-replacement of strains and florae, and can continuously and efficiently protect seabedmetals and prolong the service life of the metals.

Description

Technical field [0001] The invention relates to the technical field of deep-sea metal protection, in particular to a metal in-situ protection device and method based on deep-sea microorganisms and sediments. Background technique [0002] The ocean area accounts for about 71% of the total area of ​​the earth. It contains important oil and gas, polymetallic nodules, cobalt-rich crusts, polymetallic sulfides, natural gas hydrates and other new minerals as well as extremely rich marine biological resources. Its total economic value is Ten times the total value of land resources, the ocean has therefore become an important stage for high-tech competition among countries. More importantly, the ocean is related to the security of the country's territorial waters, so it is highly valued. In recent years, my country has put forward a national strategy to vigorously develop the marine economy, which also provides a broad development space for the development of the ocean, especially the d...
