Marine fouling organism sampling structure and sampling method thereof

Abstract

The invention discloses a marine fouling organism sampling structure. The marine fouling organism sampling structure comprises a supporting seat, an auxiliary device mounted on the supporting seat and used for lifting, an extension device mounted on the auxiliary device and used for adjusting the sampling area, and a sampling device mounted on the extension device and used for collecting ship bottom samples. The auxiliary device comprises an auxiliary motor installed on a first fixing base, a first lifting assembly installed on the first fixing base and a second lifting assembly installed on a second fixing base, wherein an output shaft of the auxiliary motor is connected with the main shaft. The second lifting assembly is symmetrical to the first lifting assembly in the front-back direction relative to the main shaft. The extension device comprises a supporting plate and a plurality of stretching assemblies, wherein the two ends of the supporting plate are installed on the first fixing base and the second fixing base correspondingly, and the stretching assemblies are installed on the supporting plate and distributed in the Y direction. The marine fouling organism sampling structure overcomes the defects in the prior art, and solves the problems that the existing ship bottom fouling organism sampling is time-consuming and labor-consuming, and the multipoint sampling work intensity is high.

Description

technical field [0001] The invention relates to the technical field of marine silt cleaning, in particular to a marine fouling biological sampling structure. Background technique [0002] Marine fouling organisms, also known as marine fouling organisms, are a general term for animals, plants and microorganisms that cling to the surface of underwater artificial facilities and cause damage or adverse effects. The harm of fouling organisms to marine facilities or structures is mainly reflected in the following two aspects: one is to cause damage to the protective coating of marine structures and corrosion of base materials, which affects the normal use of facilities; the other is to harm the pipeline system and affect the normal operation of equipment. Work. [0003] Marine fouling organisms are diverse, including bacteria, algae, and various phyla ranging from protozoa to vertebrates. The bottom of the ship has been in seawater for a long time, especially for ships that have...

Problems solved by technology

Existing sampling methods usually require divers to dive into the water to take samples manually, which is time-consuming and labor-intensive. At the same time, in order to ensure the adequacy of the research, it is necessary to expand the sampling range and multi-point sampling to obtain the distribution of fouling organisms, which results in the labor intensity and labor cost of manual sampling. greatly increased difficulty
