Hydropower station water-collecting well water surface oil stain collecting device

The invention discloses a hydropower station water-collecting well water surface greasy dirt collecting device which is characterized in that a floater is connected with a fixed pipeline with a booster pump connected in the middle, and finally the pipeline is connected into an oil treatment system with the functions of sedimentation, filtration, centrifugation and the like in an oil treatment chamber, so that water-collecting well water surface greasy dirt collection is realized. The device is simple and reliable in structure, the problems that an oil filter and an oil-water separator are not easy to install in the prior art due to narrow space and severe environment of the water collecting well are solved, and the oil dirt on the water surface of the water collecting well can be conveniently collected. Through the cooperation of buoyancy and gravity between the floater and the pipeline, the pipeline inlet is always controlled to be about 2 mm away from the water surface, so that the oil stain collection effi
