Fish passing system with tourism viewing function and fish passing method

Abstract

The invention discloses a fish passing system with a tourism viewing function and a fish passing method, and belongs to the technical field of water conservancy and hydropower ecological protection. The system comprises a dam body, a ferris wheel, a water supplementing assembly and a master controller, a releasing slide way is arranged on the upstream of the dam body, one end of the releasing slide way extends into a dam body reservoir area water body, a fish passing transfer mechanism is arranged on the downstream of the dam body, and the fish passing transfer mechanism is connected with the water body on the downstream of the dam body through a fishway; the ferris wheel is located between the fish passing transfer mechanism and the releasing slide way, a plurality of manned fish lifting mechanisms are evenly distributed on the ferris wheel, one end of the water supplementing assembly extends into a dam body reservoir area water body, the other end of the water supplementing assembly is connected with the fish passing transfer mechanism, and the master controller is connected with the ferris wheel, the fish passing transfer mechanism and the manned fish lifting mechanisms. The ferris wheel is combined with the fish upstream tracing requirement, upstream and downstream fish population gene exchange of the high-water-head water conservancy project is promoted, meanwhile, the tourism and sightseeing value of the water conservancy project is improved, and the project investment is obviously reduced.

Description

technical field [0001] The invention relates to a fish-passing system and a fish-passing method with tourism and viewing functions, belonging to the technical field of water conservancy and hydropower ecological protection. Background technique [0002] At present, in order to reduce the impact of dam barriers on migratory fish and promote the genetic exchange of fish populations upstream and downstream of the dam site, domestic and foreign methods are mainly realized by means of fish passages, imitation natural passages, fish lifts, fish collection facilities and fish locks. Fish crossing the dam. According to technical specifications and practical experience, the fish passing facilities suitable for high head water conservancy and hydropower projects mainly include fish passages, fish lifts, fish collection and transportation systems or different combinations between them. Due to the influence of many factors such as site topography and site layout conditions, it is diffi...

AI Technical Summary

Problems solved by technology

Due to the influence of many factors such as site topography and geology, site layout conditions, etc., it is difficult to design fishways alone to achieve fish passage. It is often necessary to arrange long-distance fishways to achieve energy dissipation effects. The fish passage effect is poor and the economic cost is high. For example, applying No. CN202210089204.1 patent literature provided in the ecological dam with integrated fishway has built a large number of pool chambers for energy dissipation; fish lifters and fish collection and transportation systems are rarely used in my country, and the operation process is relatively complicated. The fish passing effect has not been widely recognized
