Title:
ARCHIMEDES' SCREW GRAVITATIONAL POWER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/131162
Kind Code:
A1
Abstract:
An Archimedes' screw gravitational power system comprises an Archimedes' screw power wheel (3), a rotating shaft (2) and a supporting frame (1). Two ends of the rotating shaft (2) are arranged on the supporting frame (1) via bearings, and the Archimedes' screw power wheel (3) is fixedly sleeved on the rotating shaft via a hub (4). The Archimedes' screw power wheel (3) is a closed hollow communicating cylinder structure consisting of several identical Archimedes' screw members sequentially joined as rings, and a hollow cavity thereof is filled with a liquid. Curved lines in a cross-section of the Archimedes' screw member are two concentric Archimedes screw sectional lines reversed from the inside to the outside. In a process of rotation of the Archimedes' screw power wheel, a liquid surface height changes vertically with a rotation angle, converting potential energy into kinetic energy. The system does not depend on fossil fuels such as coal or petroleum and the like, has a low cost and does not contaminate the environment.
