Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of marine ecological environment investigation, and more particularly to a vertical offshore surface oil collection device and a collection method. BACKGROUND

[0002] Oil pollutants in the sea mainly come from offshore drilling and production platforms, shipping accidents, sudden oil spill accidents, shipping transportation, and land-based pollutant discharges into the sea, and oil pollutants entering the sea through various channels are difficult to degrade. Oil pollutants in the sea are a kind of complex petroleum hydrocarbon compounds composed of various aromatic hydrocarbons, olefins, alkanes, and heterocyclic aromatic hydrocarbons, and have the chemical properties of long duration and great ecological hazards. The influence of oil pollution in the sea on the marine ecological system, such as sea-air exchange and seawater dissolved oxygen concentration, is multifaceted. When the concentration of oil in the water is too high, it can affect the photosynthesis of marine organisms and reduce the primary productivity of the sea area. At the same time, oil in seawater can enter sediments through adsorption and sedimentation, posing a certain threat to benthic organisms. Marine organisms contaminated by oil for a long time will have an odor, and through biological enrichment and accumulation and further transmission of the food chain, they will eventually endanger human safety and health. Therefore, oil occupies a very important position in marine environmental pollutants, and the content of oil in water can directly reflect the degree of seawater pollution by oil, which is an important indicator for evaluating the quality of seawater environment and a must-measure item in marine oil pollution emergency monitoring. Therefore, in marine ecological environment investigation and evaluation and scientific research, it is often necessary to test and detect the degree of seawater pollution, especially to sample and investigate the surface oil of seawater.

[0003] According to the technical requirements of the Marine Monitoring Specification Part 3: Sample Collection, Storage and Transportation (GB17378.3-2007), oil samples in the surface layer of seawater (0-1.0 m below the sea surface) are collected. In the prior art, a floating water sampler is usually used to collect oil samples in the surface layer of seawater. The sampler is thrown into the water near the sea surface of the ship, the float ball floats on the sea surface, the sampling bottle sinks into the water under the action of gravity, the sealing cover is pulled open by the buoyancy of the float ball, the sampling bottle is filled with water, and then the pull rope in the hand is pulled up, the sealing cover is closed under the action of the spring, and thus the single sampling is completed.

[0004] It is found that the above-mentioned related technology has the following defects: because oil is light in density and floats on the sea surface to form an oil film, the oil film on the water surface is greatly disturbed when the water sampler is directly thrown into the water, which easily causes the collected oil sample content to be inaccurate; the sealing cover fixed on the water sampler easily causes mutual pollution between samples when the water sampler continuously collects samples, which causes a certain error in the detection result, and the water sampler can only complete single oil sample sampling and cannot collect parallel samples at the same time, which affects the authenticity and accuracy of the final detection result.
