Steering device, fish passing system and fish passing method

Abstract

The invention discloses a steering device, a fish passing system and a fish passing method. A water-power environment of fishes is created nearby one track through a drainage pipeline, a pump house, a fish through chamber and a stilling basin, and fishes are lured to the nearby the track; the fishes are driven and collected by a fish transporting truck, the track and a winch, and are transported to a dam until the fish transporting truck is moved to a bogie; power and the direction of a lead fish transporting truck are changed by the bogie; the fish transporting truck transporting the fishes enters a reservoir by the winch and the other track; when the fish transporting truck descends to certain depth of the reservoir, the fishes escape from the fish transporting truck at certain water pressure and enter the reservoir, and pass through the dam. The device, the system and the method can collect the fishes, transport the fishes to the dam and transport the fishes into the reservoir by only needing one set of power system and steering device and have the advantages of simple structure, extremely-less occupation, reliable fish transportation, quickness, high efficiency, energy conservation and low construction cost and operating and maintenance expenses; water resources of the reservoir are saved by using downward river water; the steering device, the fish passing system and the fish passing method adapt to any terrain, any dam height, any water level of the reservoir and water level amplitude of a downward riverway.

Description

technical field [0001] The invention relates to the technical field of water conservancy facilities, in particular to a steering device, a fish passing system and a fish passing method. Background technique [0002] With the construction of water conservancy facilities such as barrage dams, power stations, and reservoirs, a large number of primitive rivers and lakes have been blocked, resulting in the destruction of river ecological connectivity, changing or reducing fish migration channels, and directly affecting fish survival and reproduction. If it is allowed to develop for a long time, it will easily lead to a sharp decline in fish species, and even lead to the direct extinction of some fish species. [0003] Under the general environment of vigorously advocating the construction of ecological civilization, fish passing facilities such as fishways, fish locks and fish lifts are not only a water conservancy project, but also a compensatory project for the ecological bene...

AI Technical Summary

Problems solved by technology

[0004] At present, there are methods of anti-natural bypass fishway for fish passing, and there are also fish gates, fish elevators or fish collection systems for fish passing, but the above fish passing methods either occupy a large area and Either the project cost is high, or the water consumption is high

[0005] In addition, fish passing facilities also use a combination of multi-stage transfer and crane lifting to pass fish, but this fish passing method and system has complex engineering structures, long fish passing cycles, low efficiency, and requires multiple sets of power and controls. installation, difficult construction, high cost, high maintenance and operating costs
