A FISH-PASSING SYSTEM AND A FISH-PASSING METHOD WITH TOURIST ORNAMENTAL FUNCTION

This invention discloses a fish-passing system and a fish-passing method with tourist ornamental function, belonging to the technical field of water conservancy and hydropower ecological protection. The system comprises a dam, a Ferris wheel, a water supplement component, and a central controller. The upstream of the dam is equipped with a fish-release chute, and one end of the fish-release chute extends into the water body of the dam reservoir. The downstream of the dam is equipped with a fish passage transfer mechanism, and the fish passage transfer mechanism is connected to the downstream water body of the dam through a fish passage. The Ferris wheel is located between the fish passage transfer mechanism and the fish-release chute, and a number of fish-carrying and human-ascending mechanisms are evenly arranged on the Ferris wheel. One end of the water supplement component extends into the water body of the dam reservoir, and the other end is connected to the fish passage transfer mechanism. The central controller is connected to the Ferris wheel, fish passage transfer mechanism, and fish-carrying and ascending mechanisms. By combining the Ferris wheel with the upstream fish migration needs, this system promotes gene exchange of upstream and downstream fish populations in high-head water conservancy projects while enhancing the tourism value of hydropower projects and significantly reducing the project investment.
