The utility model relates to the technical field of spotted pig breeding, in particular to a drinking water cleaning device for spotted pigs, which comprises a water trough, a self-cleaning component is arranged at the top of the water trough and comprises a sealing cover, the bottom of the sealing cover is in close contact with the water trough, a motor is arranged at the top of the sealing cover, and the motor is connected with the water trough. A motor is arranged in the water trough, a rotating rod is arranged at the output end of the motor, the bottom of the rotating rod penetrates through and extends into an inner cavity of the water trough, a concave cleaning brush is arranged at the bottom of the rotating rod, and the outer surface of the concave cleaning brush is in close contact with the inner wall of the water trough. Then the sealing cover covers the drinking trough, the motor runs, the rotating rod is driven by the motor to rotate, the concave cleaning brush is driven by the rotating rod to rotate, the inner wall of the drinking trough is cleaned through the concave cleaning brush, after the drinking trough is cleaned, the sealing cover is taken out of the drinking trough, and then a worker takes out sewage manually.
