Claims

[Scope of utility model registration request]

A sedimentation pond has a pair of slope walls forming an inverted V shape on both sides of the bottom of the pond, and the flight passes over the pond water surface from above the pond bottom side wall provided between the lower ends of the slope walls. In the scum escape prevention device, a scum escape prevention means for closing the gap between the pond side wall and the flight is provided at the end of the flight so as to move forward and backward into the flight, and the flight is connected to a slope wall in the pond. A scum escape prevention device for a sedimentation pond, characterized in that a cam mechanism for advancing and retreating is provided, which moves the scum escape prevention means backward when the flight comes to the surface of the pond, and advances the scum escape prevention means when the flight comes to the surface of the pond.
