초록 ▼

Apparatus and method for inducing directed water movements for treatment of large water bodies subject to surface freezing, stagnation, bottom oxygen deficiency, or other non-uniform conditions. The apparatus consists of an open axial-flow impeller, driven by a motor, supported from below by a streamlined structure, totally submerged in a water body to avoid proximity to the surface, and resting on the bottom of the water body. The rotation of the impeller produces a water movement directed as aimed. A method is disclosed whereby dissolved oxygen is renewed in ice-bound water bodies by raising warm bottom water to melt surface ice, thereby creating an area of open water exposed to direct atmospheric oxygen diffusion and photosynthesis, and simultaneously circulating oxygen enriched water to remote parts of the water body. A further method is disclosed whereby induced circulation facilitates control of vegetation, nutrients, odors, scum, and aerobic habitat in water bodies that are stratified or otherwise have non-uniform water quality.

[ I claim:] [1.]1. A totally submerged device for circulating a water body whereby an open substantially axial flow impeller, supported and driven by a submersible electric motor unit, supported by a base resting on the bottom of the water body, connected through an electric power cord to an on-shore electric power source, retrievable to the surface for inspection, repairs, cleaning, or other maintenance, by a means not normally protruding through the surface of the water body, said retrieval means attached directly to the electric power cord, resting on the bottom of the water body, such that said retrieval means can be located and retrieved to the surface by raising the electric power cord progressively from its point of entry into the surface of the water body, produces a water movement directed as aimed to produce the desired effect.
