发明名称 Pool sweep cleaner
摘要 A pool sweep device comprised of two suction tubes that are attachable to a single suction pump. The suction pump preferably consists of a suction pump that is part of the pool's filtration system. The two suction tubes both define openings in a central plenum and the central plenum is in communication with a water intake opening or orifice. Water is sucked through the intake opening and the device is configured so that the intake opening is maintained in contact with the inner surfaces of the pool so that particulate matter resting on the inner surfaces of the pool can be sucked through the opening, the plenum and one of the suction tubes into the hose that is attached to the pool's suction pump. Positioned within the plenum is a wedge that moves between the two openings so as to alternatively cover one of the two openings. When an opening is covered, a suction force is exerted against the wedge which results in mechanical movement of the device over the inner surfaces of the pool. Further, water containing particulate matter is then sucked through the other opening which gradually reduces the suction exerted against the wedge on the first opening. Ultimately the wedge is released from the first opening and then is induced to cover the second opening which results in mechanical movement of the device. Hence, the pool sweep device travels over the bottom surface of the pool as a result of the wedge cycling between the two openings and sealing the openings.
