Title:
MULTI-STAGE TIDAL CURRENT ENERGY WATER TURBINE BASED ON REAL-TIME ADJUSTABLE GUIDE COVER ROTATION ANGLE
Document Type and Number:
WIPO Patent Application WO/2019/061841
Kind Code:
A1
Abstract:
Provided is a multi-stage tidal current energy water turbine based on a real-time adjustable guide cover rotation angle, the water turbine comprising a guide cover (1), a hub (3), which is fixedly arranged on a rotary shaft (2), and a basic impeller, which is fixedly arranged on the hub (3), and further comprising a supporting shaft (7) capable of adjusting the rotation angle of the guide cover in real time, and an energized rotary wheel with variable-radius hyperbolic spiral blades (9), wherein the hyperbolic spiral blades (9) gradually extend in an axial direction of the rotary shaft (2) according to the spiral line of a hyperbolic spiral line, are spatially intersected and twisted, and are uniformly distributed on an inner circumferential wall of the rotary shaft (2). The water turbine has a simple structure and is efficient, and not only can same be used for power generation using ocean tidal current energy, but same can also be used for power generation under conditions of a minute amount of tidal current energy from streams in a mountainous area, a mountain spring, a small reservoir, etc.
