Pull-type underwater leaked oil stain emergency collection device

Abstract

The invention relates to the field of underwater oil stain emergency recovery, in particular to a pull-type underwater leaked oil stain emergency collection device. The pull-type underwater leaked oil stain emergency collection device comprises an oil collecting cover, a flexible oil guide pipe, a liquid pump and an overwater oil collecting tank, and the oil collecting cover is used for covering the leakage position of an oil pipe and is of an inverted funnel type structure; the lower end of the flexible oil guide pipe communicates with the upper end of the oil collecting cover; the liquid pump is arranged in an overwater working box, the overwater working box can float on the water surface, and a liquid inlet of the liquid pump communicates with the upper end of the flexible oil guide pipe; and the overwater oil collecting tank floats on the horizontal water surface and can communicate with the liquid outlet of the liquid pump so as to collect leaked oil dirt into the overwater oil collecting tank. According to the pull-type underwater leaked oil stain emergency collection device, the posture of the oil collecting cover in water can be monitored in real time through a horizontal detector, so that a plurality of air bags can be matched with an air bag air-blowing mechanism, local buoyancy of the outer circumferential surface of the oil collecting cover is changed, and the oil collecting cover covers the oil leakage position.

Description

technical field [0001] The invention relates to the field of underwater oil pollution emergency recovery, in particular to a towed underwater oil pollution leakage emergency collection device. Background technique [0002] In recent years, with the continuous development of offshore oil and gas resources, the scale of the submarine pipeline network will increase day by day, which will pose potential risks to the marine ecological environment. Economic losses may also lead to international disputes. What's more serious is that the leaked crude oil floats in the ocean or other waters, which will seriously damage the environment of the ocean, coast and other waters, causing ecological damage that is difficult to repair. However, there have been many major safety tests on offshore platforms and submarine pipelines at home and abroad, which have brought huge economic losses and caused serious pollution of the marine ecological environment. For example, in 2007, the Chilean subm...

AI Technical Summary

Problems solved by technology

[0004] When the device puts in the oil collection cover, it is affected by the water flow and cannot adjust the posture of the oil collection cover in the water, thus making it impossible to ensure that the oil collection cover can be accurately placed above the underwater oil spill point
