<p>PURPOSE:To clean up economically and efficiently sewage by driving a pump type piston by the rotation of a spherical wind wheel for all wind directions to suck and eject the water of a lake, etc. CONSTITUTION:The rotation of the spherical wind wheel 1 for all wind directions is transmitted to a revolving shaft 3 and gears 4, 8, by which the pump type piston 10 is driven to suck and eject the stagnant water A in the lake, etc. thereby aerating said water. The stagnating water in the lake, etc. is thus economically and efficiently cleaned up.</p> |
