Abstract: A pollutant collecting pump for water surface comprises a power device (1) and a pollutant collecting barrel (6). The power device (1) is connected to the pollutant collecting barrel (6). A pollutant inlet (4) is provided on the upper portion of the pollutant collecting barrel (6), and a pollutant outlet (5) is provided on the lower portion of the pollutant collecting barrel (6). A blade (2) is provided outside the pollutant collecting barrel (6), and an axis of the pollutant collecting barrel (6) is perpendicular to a rotating surface of the blade (2). The pollutant inlet (4) is positioned above the blade (2). The pollutant collecting pump for water surface is adapted to collect pollutants distributed on water surface with low density and small thickness, and has the advantages in simple structure, low manufacturing cost, convenient operation and thorough collection.
