A fully automatic and simple fish passage facility and its application method

Abstract

The invention discloses a fully automatic and simple fish passing passage facility, which comprises a fish passing passage, a fish collecting and luring system, a hydrodynamic fish passing system, a fishway monitoring system and an integrated control system. The fish passing channel includes the upstream fish passing channel, the fish lifting channel, and the downstream fish passing channel; the fish collection and luring system includes the fish blocking electric grid, the fish luring light, the automatic bait feeding machine and the water flow fish luring equipment; the hydrodynamic fish passing system includes the upstream Electronic control gate, downstream electronic control gate, fish transport buoyancy tank, pressure sensor and water supply equipment, water supply equipment includes water supply pipe and water supply pipe valve; fishway monitoring system includes fish observation equipment, underwater camera, fish observation equipment The species and quantity of fish entering and exiting the fish floating tank are monitored in real time. Not only can the fish go up and down to complete the gene exchange, but it also has innovations such as simple operation, low construction and operation maintenance costs, realizes high-efficiency and automated fish passing, and improves the survival rate of fish.

Description

technical field [0001] The invention relates to a fish passage, in particular to a fully automatic and simple fish passage facility and a method of using the same. Background technique [0002] After the construction of dams in water conservancy and hydropower projects, fishes are blocked from going up and down, resulting in obstacles to fish gene exchange and adverse effects on fish biodiversity. Corresponding fish passing facilities must be built to reduce the impact on fish resources. At present, the main fish passing facilities in China are fish passages and fish lifts. [0003] The fish pass is a fish passage with a certain slope built from the top to the bottom of the dam. Through the design of the relevant characteristic parameters of the fish pass, the hydrological characteristics of the fish pass are suitable for the fish to go up and down. The fish pass is a channel suitable for passing fish through low dams. When the dam is high, a longer fish pass must be built...

AI Technical Summary

Problems solved by technology

The fish lifting machine solves the problem of passing fish over high dams, but the entire fish passing process is complicated, the automation is difficult, and the construction and operation and maintenance costs are high

Moreover, the fish stay in the fish collection box for a long time, and the living conditions of the fish are affected
