Marine fouling organism sampling research device and underwater long-term monitoring device

Abstract

The invention relates to the field of marine resource research, in particular to a marine fouling organism sampling research device and an underwater long-term monitoring device. The underwater long-term monitoring device comprises a fixing assembly, an underwater releaser, a mooring rope, a floating ball and a marine fouling organism sampling research device. The fixing assembly is connected to the underwater releaser, and the marine fouling organism sampling research device is arranged on the mooring rope. Under the action of gravity of the fixing assembly, the fixing assembly sinks into theseabed. The floating ball floats on the sea surface, so that the mooring rope and the marine fouling organism sampling research device mounted on the mooring rope are suspended in the sea. The marinefouling organism sampling research devices are arranged on the mooring rope at intervals in the length direction of the mooring rope; the marine fouling organism collecting device can suspend at different depths of the sea, can collect fouling organisms at different depths of the sea, and can provide samples for researching the variety and distribution of the marine fouling organisms and the relationship between the marine fouling organisms and marine hydrodynamic force, thereby providing a theoretical basis for activities such as marine scientific fundamental research and marine economy.

Description

technical field [0001] This application relates to the field of marine resources research, in particular to a marine fouling biological sampling research device and an underwater long-term monitoring device. Background technique [0002] Marine fouling organisms are the general term for marine animals, plants and microorganisms that grow on the bottom of ships, pipelines, buoys and artificial facilities. There are many kinds of marine fouling organisms, including bacteria, algae, and various phylum organisms from protozoa to vertebrates. According to statistics, there are more than 2,000 species of marine fouling organisms in the world, among which the most harmful ones are barnacles, oysters, mussels, Tube worms, etc. Marine fouling organisms have caused great harm to offshore platforms and navigation equipment, and seriously hindered human activities such as maritime economy.

Marine fouling organisms have caused great harm to offshore platforms and navigation equipment, seriously hindering human activities such as maritime economy

A large number of fouling organisms will increase the navigation resistance of marine vessels; the propagation of fouling organisms will cause damage to the anti-corrosion protection layer of ships or offshore buildings, and accelerate the corrosion process of metal components; reduce the sensitivity of equipment, instruments and rotating parts in seawater, and interfere Normal operation of ocean acoustic instruments

[0003] However, there are few studies on marine fouling organisms at present, which cannot provide a theoretical basis for basic research in marine science, marine economy and other activities.
