Title: METHOD AND SYSTEM FOR CIRCULATORY HYDROELECTRIC GENERATION BY USING BUOYANCY SERIES WATER LIFTING
Abstract:
Disclosed is a method for circulatory hydroelectric generation by using buoyancy series water lifting. A buoyancy lifting apparatus formed by series connection of multiple stages of buoyancy buckets and lifting baskets is provided, water is lifted to a set hydroelectric generation height by the aid of buoyancy by using the buoyancy lifting apparatus, so as to realize hydroelectric generation; lake and pond water, river water or seawater flows into the multiple stages of lifting baskets and buoyancy buckets in sequence, the water is lifted to the set hydroelectric generation height step by step by depending on the buoyancy thereof by means of forming series multi-stage lifting, and the lake and pond water, river water or seawater is lifted to the hydroelectric generation height finally; on/off states of a water discharge switch and a water inlet switch of the buoyancy bucket and the lifting bucket of each stage are controlled by using a control apparatus; the water lifted to the set height falls into lakes and ponds, rivers or sea areas again to realize circulatory hydroelectric generation. In the present invention, other mechanical power is not required, and dams need not to be built, and accordingly, the method does not cause any influences on the surroundings, and needs low building cost and has a wide application range.
