Solution Overview

Problem

Current ocean current power generation technologies face challenges such as low conversion efficiency and high manufacturing costs, with limited geographical suitability and equipment corrosion issues, making them less viable for widespread adoption.

Innovation Solution

A power generating system is designed to harness kinetic energy from fluid flows around a structural body by utilizing a supporting device with defined regions (stream-facing, side-stream, and vortex regions) and power generating units, such as turbine or vibration generators, to convert down flow, lateral flow, and vortex flow into electrical energy, which can be integrated with existing offshore or onshore apparatus.

Solution Approach 1:

The supporting body serves dual functions: it provides structural support for the power generation device while simultaneously acting as a flow guide to generate down flow and vortex flow. This multi-functionality eliminates the need for separate flow guide structures, reducing manufacturing cost while improving power generation efficiency by utilizing multiple flow patterns (down flow, lateral flow, vortex flow) around the supporting body

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention utilizes three-dimensional flow patterns around the supporting body by defining multiple regions (stream-facing region, side-stream region, vortex region) at different spatial positions. Power generation units are strategically placed in these different spatial regions to capture kinetic energy from down flow, lateral flow, and vortex flow simultaneously, thereby improving overall conversion efficiency
