SURFACE CLEANER AND RETRIEVAL UNIT

摘要

This invention is directed to a cyclonic power system and method of using the system to clean flat surfaces. The cyclone power system includes a driven spindle (60) that is mounted for rotation about its longitudinal axis. There are a plurality of radially extending straight rods (54) extending from the spindle (60). Curved blades (52) are connected at one end to the spindle and at their other end to the free end of a straight rod. The centrifugal force, generated as a result of the rotation of the driven spindle is not effective to cause the straight rods, which are constructed of stainless steel, to lengthen and since the curved blades are connected to the straight rods, the centrifugal force is not effective to lengthen the curved blades. In an embodiment of the invention a perforated disc is secured to the bottom surface of the spindle and to the free ends of the straight rods. In this embodiment the water and debris is pulled up through the perforation in the disc. The perforated disc protects the rotary member from heavy projectiles that are lifted from the surface to be cleaned, adds to the stability to the rotary member and has eliminated of the need for the supports extending between the mid-portion of the curved blades and the straight rods. In addition to the above improvements the flow through the perforations in the disc is limited to the upward flow and once water laden with debris has passed through the perforations in the disc it remains above the disc and is swept to the discharge.
