Water surface floating pollutant separation device

A water surface floating pollutant separation device comprises a lifting mechanism, a dumping mechanism and an external rack, the lifting mechanism comprises a driving component and a lead screw structure connected with the driving component, the dumping mechanism comprises a shell connected with the lead screw structure, a turnover net is connected in the shell through a turnover structure, and the turnover net is connected with the external rack. The overturning structure comprises gears arranged at the two ends of the shell, after the overturning net is driven by the shell to ascend, the gears are meshed with an external rack to enable the overturning net to rotate, water pollutants are separated and filtered by arranging the overturning net capable of automatically overturning, and the overturning net can be suitable for being used for separating and filtering water pollutants when water eutrophication occurs in lakes or oceans. The method helps governments and farmers to solve the problem of water eutrop
