Description
Technical field
The present invention relates to fish structure crossed by a kind of dam, the rail mounted in particular for middle and high head barrage hinge crosses fish
Structure.
Background technology
The fish pass structure of prior art mainly has fish pass (also known as fishway), fish lock, cable machine formula fish lift, boat for collection and transportation of fish
Deng.Wherein fish pass is a kind of the more commonly used fish pass structure pattern, and its advantage is simple to operate, runs fraction height, can ditch
Logical upstream and downstream water system, continuous fish excessively under field conditions (factors), operational and administrative expenses is low, and under optimum conditions, other aquatic lifes
Thing can also pass through fish pass, preferably acts on to safeguarding that original ecological balance has, and its shortcoming is that fish pass is typically longer, in hinge
More difficult arrangement, cost is too high, general 80m about dam body, cross the investment of dam fish pass and be about 1.0 hundred million, construction and operational management difficulty
Increase.Increase with height of dam, investment increases more, construction and operational management is more difficult；Fish trace back migration to be needed to expend
Large energy, unfavorable for fish egg reproduction；The flow velocity of fish pass, fluidised form are affected relatively by the change of upstream and downstream water level and flow
Greatly, it is unsuitable for high dam and cross fish.Fish lock, cable machine formula fish lift and boat for collection and transportation of fish are manual operation and cross fish means it is adaptable to high dam
Cross fish.The operation principle of fish lock is similar to ship lock with the method for operation, and its advantage is to be suitable for the certain luffing of upper pond level, shortcoming
It is on major project, fish lock arranges that impact is larger, investment is big, and operates operation complicated, and later stage operational management and maintenance procedure are multiple
Miscellaneous.
As shown in figure 1, being the cable machine formula fish lift of prior art, 21- cable-support；22- reservoir；23- dam；25- cable
Rope；26- downstream fish gathering canal；27- dress hopper car fortune fish direction.Cable machine formula fish lift is to rise fish using machinery to help fish with transhipment facility
Cross dam, its advantage is that suitable high dam crosses fish, and adapts to the larger luffing of reservoir level it can also be used to relatively long distance transports fish
Class, shortcoming is to need the higher cable machine support of setting and larger bracket basis, difficult arrangement；Because itself transport power of cable machine has
Limit, fortune fish amount is less；Dam crest cable machine need to cross over two sides (or concave bank two ends) cable machine arrangement more complicated, length of warping winch is longer, transport fish
Speed is slow, and fish are in fortune fish equipment for a long time, are constantly in panic states, unfavorable to egg reproduction phase fish；Cable is
Flexible structure, during calm fortune fish produce rock larger, on fish affect bigger；It is subject to wind-force and inside even from weather in operation
Larger, upstream transfer operation is more complicated, runs and overhauls costly.Boat for collection and transportation of fish, by collecting fishing boat and fish-carrying boat forms, utilizes
Drive fish device and fish is driven in fish-carrying boat, then throw in fish into the suitable waters in upstream after dam is crossed in navigation structure, therefore it is only
Be limited to the multi-purpose project having navigation structure, and its climate ambient influnence be larger, be difficult to trap demersal fishes again it is difficult to
Ensured fish effect.Above-mentioned various fish pass structure has utilization in engineering, is shown by various engineering practices, crosses fish effect
Poor.
Content of the invention
The technical problem to be solved is to provide a kind of flexible arrangement, adapts to various landform, being used for of dam type
The rail mounted of middle and high head barrage hinge crosses fish structure.
The technical solution used in the present invention is：A kind of rail mounted for middle and high head barrage hinge crosses fish structure, bag
Include dam body, be arranged at the fish pass and the collection fishpond that make fish migration in dam body downstream, fortune hopper is located in collection fishpond, is arranged at dam crest
Rotary crane, the wire rope hoist on dam crest platform, along downstream dam slope arrangement oblique orbit beam, be connected to oblique orbit beam and
Horizontal rail beam between collection fishpond, is provided with the electric block for crawl fortune hopper, in oblique orbit on horizontal rail beam
The fish transportation vehicle frame that wire rope hoist is powered is provided with beam, fortune hopper can be lifted by electric block and along horizontal rail beam
It is transported on the fish transportation vehicle frame on oblique orbit beam.
Described horizontal rail beam and oblique orbit beam, away from supporting surface maximum height≤6m, transport hopper maximum fortune fish weight 0.5t.
The hauling speed of described wire rope hoist is 30m/min.
Described rotary crane maximum working radius are 50m, revolution boom tip minimum hoisting weight >=2.5t.
A kind of rail mounted for middle and high head barrage hinge crosses fish structure, including the dam body of arch dam, is arranged at dam body
The fish pass and the collection fishpond that make fish migration in downstream, fortune hopper is located in collection fishpond, is arranged at the rotary crane of dam crest, behind dam
Wire rope hoist on platform, is connected to the track girder between dam rear platform and collection fishpond, above track girder and collection fishpond
Rise fish frame, rise fish frame on be provided with for crawl fortune hopper electric block, in rail beam is provided with wire rope hoist
The fish transportation vehicle frame being powered, fortune hopper can be by electric block lifting, the fish transportation vehicle frame that is transported on track girder.
Described track girder, away from supporting surface maximum height≤6m, transports hopper maximum fortune fish weight 0.5t.
The hauling speed of described wire rope hoist is 30m/min.
Described rotary crane maximum working radius are 50m, revolution boom tip minimum hoisting weight >=2.5t.
Beneficial effects of the present invention：Avoid traditional fish pass structure, fish pass is longer, more difficult arrangement, cost in hinge
High disadvantage, avoid simultaneously traditional fish pass structure be typically only applicable in, the situation of low water head barrage hinge and biography
The disadvantages such as fish operational management is difficult, fish are afraid of one's shadow transported by system cableway.Rail mounted crosses fish structure during utilization, and fish pass through
The fish pass in dam downstream is braved against the current, and swims into collection fishpond, fishes for fish by the fortune hopper automatically fished for, will be transported using electric block
Hopper is lifted and is transported on the fish transportation vehicle frame at track top, faster along inclined plane by the wire rope hoist located at rail end
Speed, smoothly draw to dam crest platform nearby, finally by dam upstream rotary crane steadily, be efficiently hoisted to reservoir area bank and put
Raw, complete the demand that dam is crossed in fish migration.
