Abstract
The invention discloses an upstream and downstream fish dam-passing and communicating device which comprises a dam (1), wherein a fish collection system (2) in front of the dam is arranged at the upstream part of the dam (1); a fish collection system (3) behind the dam is arranged at the downstream part of the dam (1); and a generator (5) is arranged in a power generation plant (4) and is connected with a group of reversible pump turbines (6). The upstream and downstream fish dam-passing and communicating device can meet the requirements that upstream and downstream fishes communicate; the influence on arrangement of hydropower engineering is small; and the operation is simple. The upstream and downstream fish dam-passing and communicating device has positive effects on reduction of the influence of water conservancy and hydropower engineering on fish migration and promotion of river ecological protection.
Description
Technical field
The present invention relates to a kind of upstream and downstream Fish and cross dam ac equipment, belong to power station fish protection technical field.
Background technology
The construction of Hydraulic and Hydro-Power Engineering dam, has blocked fish population exchange, and fish pass structure is the critical facility recovering aquatile exchange.
Existing fish pass structure mainly has several forms such as fish pass, fish lock, fish lift and transporting something containerized fish system.Wherein, fish pass needs open landform to meet the needs of length and bigger on work arrangement impact.Fish lock and fish lift carried out fish by human assistance measure after being attracting, not only big on work arrangement impact, and investment is bigger.Transporting something containerized fishing boat, in view of the problem of safety, is not suitable near the region attracting of Factory Building, and attracting effect is bad, and fish causes in transportation certain injury, and expends bigger human and material resources, is delayed that Fish are smooth crosses the shortcomings such as dam time.
Summary of the invention
It is an object of the invention to, it is provided that a kind of upstream and downstream Fish cross dam ac equipment, the demand exchanged to meet Fish upstream and downstream to carry out, and coordinate the contradiction between Hydraulic and Hydro-Power Engineering and ecological environmental protection, thus overcome the deficiencies in the prior art.
The technical scheme is that and be configured so that
A kind of upstream and downstream Fish of the present invention cross dam ac equipment, and including dam, dam upstream is provided with fish collection system before dam, and dam downstream is provided with fish collection system behind dam；It is provided with electromotor in power plant building bottom dam；Electromotor and one group of Reversible Pump-Turbine connect.
In aforementioned means, described Reversible Pump-Turbine is to possess the Francis turbine of water pump function.
In aforementioned means, before described dam, fish collection system is positioned at above the advance mouth of a river, Reversible Pump-Turbine dam.
In aforementioned means, after behind described dam, fish collection system is positioned at dam at Reversible Pump-Turbine tail water mouth.
Owing to have employed technique scheme, compared with prior art, the present invention can meet the requirement that Fish upstream and downstream carries out exchanging to the present invention, and affects little on the layout of hydroelectric project, and runs the simplest.Use the present invention for reducing the water power hydraulic engineering impact on fish migration, promote the ecological protection in river to have positive effect.
