Novel fish gathering station structure

Abstract

The invention discloses a novel fish gathering station structure which is applied to a dam passing project in the migration period of migratory fishes. The novel fish gathering station structure is provided with a fish gathering station building, a lifting mechanism and an automatic fish trapping box. The main function of the fish gathering station building is to improve the trapping efficiency of migratory fishes by means of ultrasonic waves and the like; necessary support is provided for the lifting mechanism through a prefabricated steel truss, a bracket platform and an upper bent frame; and the construction period is shortened by mounting a prefabricated steel truss underwater. The main function of the lifting mechanism is to lift trapped migratory fishes from a riverbed to the transfer platform, and the single-time operation energy consumption of the fish gathering station can be effectively reduced in cooperation with a balancing weight. According to the automatic fish trapping box, the migratory fishes can be effectively prevented from being injured during trapping, and the migratory fishes can enter automatic front and rear valves in a barrier-free mode and can be rapidly transferred. Under the condition of a high dam, construction of a fishway is difficult, and the novel fish gathering station structure provides a fish passing method which is safe, reliable, feasible in technology, convenient to construct, economical, reasonable and eco-friendly.

Description

technical field [0001] The invention relates to a novel fish-collecting station structure, which belongs to the technical field of water conservancy and hydropower engineering. Background technique [0002] With the advancement of water conservancy and hydropower projects, my country has built a large number of reservoir dams on major rivers. While the dam is benefiting, it blocks the migration path of migratory fish. Therefore, it is a safe, reliable, technically feasible, economically reasonable and ecologically friendly solution to build fish overturning facilities to assist migratory fish to cross the dam. Middle and low dams generally build fishways to assist fish to turn over the dam. For high dams, fish ladders, fish collection stations or artificial fishing are often used. For rivers with narrow valleys and steep bank slopes, the construction period of conventional fish collection stations is longer, the investment is larger, and the effect of trapping migratory fis...

AI Technical Summary

Problems solved by technology

For rivers with narrow valleys and steep bank slopes, the construction period of conventional fish gathering stations is longer, the investment is larger, and the effect of trapping migratory fish is not good.
