Abstract
An improved water turbine apparatus includes a rotating waterwheel having a plurality of water-receiving buckets arranged about its periphery. Water is delivered to the buckets at a first, upper location and drained from the buckets at a second, lower location. The water is retained in the buckets during rotation between the first and second locations by a curved, fixed turbine wall. A portion of the water delivered to the buckets may be pumped from a well or reservoir, the water drained from the buckets being used to replenish the reservoir. The reservoir can be used to augment a second, variable water source to maintain continuous and consistent turbine output.
Claims6
A water turbine apparatus, comprising an upright rotating waterwheel journaled for rotation about a horizontal axis coupled to an output shaft, said waterwheel having a plurality of water-receiving buckets positioned about an outer periphery thereof;
- delivery means for supplying water to said buckets seriatim at a location proximate the top of the waterwheel;
- an exit means for draining water from said buckets at the bottom of the waterwheel, said buckets being of a generally trapezoidal shape in cross-section and having opposed first and second ends, said first end being open for the receipt of water, said buckets being arrayed around said outer periphery in an orientation whereby a first open end of a bucket is directly above the second end of the bucket when the bucket is adjacent said delivery means for fill thereby;
- and cover means fully surrounding the outer periphery of said waterwheel between said delivery means at the top of the waterwheel and said exit means at the bottom of the waterwheel for retaining water in said buckets during the rotation of said buckets from said location proximate the top to the bottom of the waterwheel, said delivery means and exit means each comprising a conduit mounted to said cover, said cover extending about the outer periphery of the waterwheel past said delivery means and exit means.
