CLEANING ROBOT FOR SEDIMENTATION BASIN

PURPOSE:To easily remove and recover algae without changing water quality of supernatant liquid by using a robot main body as a buoyancy body, sucking water of the outside from the suction plate of a side wall and moving the buoyancy body. CONSTITUTION:The main body 5 of a cleaning robot is formed into a box body capable of floating on the water surface of a sedimentation basin. Furthermore, suction ports 12 are provided respectively on four faces. Algae stuck to the overflow notch parts 2a of supernatant liquid are sucked, removed and recovered by using a pump. A crawler type chain is detached from engagement of the overflow notch parts 2a at a time for changing the direction. A hollow bend arm integrated with an endless chain 10 is turned at 90 deg. and engaged with the unevennesses of the following weir. Thereby, algae are easily removed and recovered by remote operation. Algae are removed without changing water quality of supernatant liquid.
