Embodiment 1

[0037]A sampling tool capable of quantitatively measuring the thickness of an oil spill film, comprising a handle 1, a screen 2 and a screen frame 3, the screen 2 is in the shape of a dustpan, and the mesh aperture of the screen is 0.1mm. Set on the screen frame, the screen is connected with the screen frame along the edge of the screen frame, the gap formed between the screen and the screen frame is not larger than the mesh of the screen, and the screen is erected on the handle bar On one end, the area of ​​the screen frame is 30cm×25cm, and the included angle between the holding rod and the plane where the screen frame is located is 45°. The mesh of the sieve can be circular, oval, rectangular or rhombus, etc. The sieve and the sieve frame are made of stainless steel or iron, so as to avoid the sampling pollution of the oil product by the dissolution of the organic material components.

[0038] Further, in this embodiment, the handle 1 is an aluminum alloy tube or a stainle...

Embodiment 2

[0055] This embodiment has been further improved on the basis of embodiment 1:

[0056] The optimum mesh aperture of the screen is 0.5mm, the screen frame is rectangular, and the area of ​​the screen frame is 35cm×25cm. It not only improves the representativeness of collected samples, but also ensures the operability of the sampler.

Embodiment 3

[0058] This embodiment has been further improved on the basis of embodiment 1:

[0059] The optimum mesh aperture of the screen is 1.0mm, the screen frame is rectangular, and the area of ​​the screen frame is 45cm×35cm. It not only improves the representativeness of collected samples, but also ensures the operability of the sampler.

[0060] In addition, the screen frame can also be square or circular, etc., to facilitate the calculation of the sampling area.

[0061] Using the sampling tool of the present invention to conduct experiments at the oil spill site of Penglai 19-3 oil field, the experiment proves that this method is effective in monitoring sea surface oil pollution (thicker oil film), and it is completely feasible to accurately monitor the thickness of surface oil pollution.

Abstract

The invention belongs to the technical field of ocean spilled oil pollution detection, in particular to a sampling tool capable of quantitatively measuring thickness of an oil film of spilled oil. The sampling tool comprises a holding rod, a screening net and a screening net frame. The screening net is in a dustpan shape, the mesh apertures of the screening net are 0.1 mm-1 mm, the screening net is fixedly arranged on the screening net frame, the screening net is connected with the screening net frame along the edge of the screening net frame, and a gap formed between the screening net and the screening net frame is not larger than the meshes of the screening net. The screening net frame is arranged at one end of the holding rod, the area of the screening net frame is (30-45) cm*(25-35) cm, and the included angle between the holding rod and the plane where the screening net frame is located is 45 degrees. The sampling tool can accurately measure the thickness of the oil film of the spilled oil, the monitoring precision of an oil spilled sea area with a thick oil film and with the oil film thickness being 2 mm or above is increased, an important basis is provided for precisely estimating the amount of spilled oil flowing into the sea in time, and a technical support is provided for oil spilling disaster warning and emergency management.

Description

technical field [0001] The invention belongs to the technical field of marine oil spill pollution detection, in particular to a sampling tool capable of quantitatively measuring the thickness of an oil spill film. Background technique [0002] With the rapid development of the global marine transportation industry and offshore oil exploration industry, the occurrence of marine oil spill pollution accidents is becoming more and more frequent. Marine oil spill pollution accidents not only bring serious harm to the world's marine ecological environment, but also seriously threaten the living environment of human beings. More importantly, these pollution damage accidents have caused huge economic losses. How to evaluate these losses objectively, fairly and scientifically, deal with oil spill accidents as soon as possible, and protect the legitimate rights and interests of both parties in the accident has attracted more and more attention. Although there are many factors involv...
