Description
Technical field
The present invention relates to hydraulic and hydroelectric engineerings and ecological, environmental protective engineering field, and in particular to integrated water is driven in a kind of induction
Fish device and its application method are crossed in dam.
Background technique
Due to the various engineering demands such as power generation, irrigation, landscape, water conservancy, people often build dam in the water systems such as river
Equal water retaining structures, these water retaining structures often hinder or have intercepted the migration of the aquatic organisms such as straddling fish stocks in river, right
The water-based aquatic organism such as original river causes direct or indirect injury even to destroy.With China's water energy and the development of aquatic resources
The continuous improvement of degree, mainstream and the branch that will there are the water retaining structures such as more and more various barrages to be built in river
On stream.Although people are also studying and are paying close attention to always the migration of the aquatic organisms such as straddling fish stocks before building barrage, inhabiting, breed
The problems such as, fish pass and ecological flow bleeder have been built in many conditional power stations, and some power stations are also specially built
Fish multiplication station.But for various reasons, guarantee fish migration, the engineering effect inhabited, bred are barely satisfactory.Such as it repairs
It is built in the East China some hydropower station of 1970s, although having built one between its dam spillway and power plant building
Fish pass, attempt allow straddling fish stocks to sail against the current by artificial fish pass, the upper pond of dam are swum over to from the downstream river course of dam, but
Actual effect is very unsatisfactory, also almost discards because no fish passes through at present.
With the enhancing of compatriots' environmental consciousness, the power station for having fish system is increasing, but really has fish function
Effect crosses fish system almost without then having to look for another way --- such as built fish elevator, fish multiplication station, using people
Work fishing rear vehicle the methods of is had bad luck and means, to mitigate obstruction and injury to aquatic organisms such as straddling fish stocks.Regrettably
Often things turn out contrary to one's wishes or effect is extremely limited or operating cost is high for the above method and means.Straddling fish stocks it is inverse
Flowing migration habit is that it is formed in very long evolutionary process.The artificial fish pass generally used in engineering at present crosses fish mode, although
The partial parameters such as flow rate of water flow, flow have catered to part straddling fish stocks, but often project scale is huge, and cost and O&M are costly
It is high, and cross fish effect and be difficult to reach perfect condition.Traditional dam crosses fish system and generallys use the artificial fish pass of gravity flow, the fish
Not only structure is complicated in road, takes up a large area, and project cost is high, and limitation is larger.It is more than particularly with upstream and downstream water-head
For 50 meters of dam, traditional gravity flow fish pass is almost difficult to realize, even if realizing reluctantly, construction scale, construction investment
And it is considerable, more fatal defect was that fish effect is often barely satisfactory.It is other similar in manually arresting the fish having bad luck
Class crosses dam mode, and the scaring and injury for fish are also conceivable.
