Abstract

This invention discloses an energy harvesting device and multi-energy unit that utilizes the impact of river and lake water drop to generate tidal energy, adaptable to various tidal energy development needs. It includes a generator set and a power generation chamber, with an impeller connected to the generator set. Through inlet and outlet water pipes, it adapts to different water conditions, stably capturing the potential and kinetic energy contained in the water. Water flows through the inlet pipe into the power generation chamber, driving the impeller to rotate, converting the water's potential energy into the impeller's kinetic energy, which is then converted into electrical energy by the generator set. Coaxially mounted follower blades drive the water flow back to the river or into storage. A limiting cylinder improves the stability of the rotating shaft, reducing equipment failure rates. The overall structure is compact, requiring no large-scale civil engineering construction, and has minimal impact on the river and marine ecological environment. It enables efficient and flexible development of tidal energy, adapting to the clean power supply needs of various coastal scenarios.
