Description
Technical field
The present invention relates to a kind of natural flow station, more particularly, to a kind of minisize ecological natural flow station, belongs to water conservancy water
Electrical engineering Building Design building technology field.
Background technology
Fish pass is the passage for fish migration.Described with popular language, some fish, which have from lower reaches of river, to be migrated to river
The habit of upstream oviposition is flowed, after river has blocked river since artificial origin has such as built checkdam, fish are upstream whirled
The passage of trip will be destroyed.In order to protect the habit of fish, it is necessary to which passing through dam builds artifical flume as fish migration
Passage, i.e. referred to as fish pass.Current enter fish pass from upstream, flow out fish pass from downstream, but fish are from downstream into fish pass, from upper
Fish pass is swum out of, thus fish pass upstream intake is referred to as fishway exit, and fish pass downstream water outlet is fish pass import.
In order to realize that fish pass crosses the purpose of fish, fish pass usually requires to meet claimed below：First, depth of water requirement, fish pass domestic demand
Keep 1.0~1.5m depth of waters；2nd, slope requirement, in order to enable fish along current upstream migration, flow rate of water flow in fish pass
It is less than the speed of fish migration, this requires fish pass needs to keep a gradient that is relatively slow and stablizing；3rd, when upper pond level becomes
During change, fishway exit needs the measure that can adapt to SEA LEVEL VARIATION, it is ensured that under various water levels, it is long-term in fish pass keep 1.0~
1.5m the depth of water.
In order to meet above-mentioned requirements, at present frequently with following two fishway exit arrangements in engineering：
1 existing program one
Fishway exit is arranged in checkdam upstream by the program, and sets multiple fishes at the same time along elevation in eulittoral zone
Road exports, and each outlet is controlled using 1 bulkhgead gate.The characteristics of structure, is：1st, fishway exit is arranged
In checkdam upstream；2nd, in upper pond level luffing area, fish pass multiple outlets along elevation arrangement, each fishway exit is on elevation
It is mutually linked；3rd, each fishway exit arranges the lower stream that sluices of 1 plate steel gate control.The major advantage of the structure is：
In upper pond level luffing area, each elevation section is arranged with fishway exit, when upper pond level is located at a certain elevation, only needs to open
The gate of corresponding elevation fishway exit, and close the gate of other fishway exits, you can meet 1.0~1.5m depth of waters in fish pass
It is required that.The major defect of the structure is：1st, fishway exit is arranged in upstream, longer to length along river, corresponding excavated volume
Or concrete works amount is larger, fish pass construction investment is larger；2nd, fishway exit quantity is more, and needs the feelings according to upper pond level
Condition, carries out each gate opening and closing in time, when upper pond level amplitude of fluctuation is larger, changes more frequent, fishway exit gate
Operation control is also relatively complicated.
2 existing programs two
Fishway exit is combined arrangement with checkdam by the program, and is set gradually along the water blocking axis of dam in eulittoral zone more
A fishway exit, each fishway exit is controlled using 1 bulkhgead gate.The advantages of structure, is：1st, by fishway exit with
Checkdam combines arrangement, is arranged successively along the water blocking axis of dam in each fishway exit horizontal direction, elevation is mutually linked on direction, phase
Adjacent fishway exit is connected by the linking channel in downstream, and lowest elevation fishway exit is connected by being connected channel with fish pass import；
2nd, for single fishway exit, upper middle part is provided with 1 plate work gate opening/closing, and downstream sets linking channel and next stage fish
Road outlet connects.The major defect of the structure is：1st, to adapt to the requirement of range of stage, upstream needs to set along the axis of dam more
A fishway exit, it is impossible to suitable for the checkdam of Narrow Valleys；2nd, since each fishway exit is both needed to set 1 plate work lock
Door, and need, according to the situation of upper pond level, to carry out each gate opening and closing in time, when upper pond level amplitude of fluctuation is larger,
When changing more frequent, the operation control of fishway exit gate is also relatively complicated.
Either above-mentioned any scheme, its have one it is obvious the characteristics of, that is, it is all deeper applied to reservoir water level,
In the larger large and medium-sized hydroelectric project of moisture storage capacity.And it is smaller in some water flows, reservoir water level is shallower, and moisture storage capacity is relatively also smaller
Mini engineering in and do not apply to.Therefore, find it is a kind of adapt to middle-size and small-size hydraulic and hydroelectric engineering cross fish system become in order to
Those skilled in the art are badly in need of the technical problem solved.
Furthermore for water channeling type micro generation station, since building for checkdam has blocked current, i.e., usual current are by drawing
Water system has been transported in the power plant building of downstream red switch cluster engine and has generated electricity, in order to meet checkdam and the big Power Plant in downstream it
Between section riverbed ecological water requirement, usually through the pipeline set in checkdam, in non-flood discharge period downstream riverbed water delivery.
Some engineerings just utilize checkdam interior conduit aerial drainage, and low power hydroelectric generator, that is, Midget plant hair is set in checkdam downstream
Electricity, not only ensure that the requirement that downstream ecology supplies water, but also achieve power benefit.But since checkdam has blocked current, have and whirl
Swim habit the shoal of fish just can not migration lay eggs to upstream.This is the technical problem that this small-sized water channeling type power station has to examine.
