Abstract

The utility model discloses a river dam creature tunnel used for solving the problem of the creature traveling of building water valve dams on rivers. The utility model is composed of a creature tunnel cave, an upper reaches valve door, a lower reaches valve door, an upper reaches water inlet hole, a lower reaches water outlet hole, an upper reaches pressure regulating chamber, a lower reaches pressure regulating chamber, a wall lamp and a monitoring apparatus. As the river dam cuts off the river at the middle, the creature traveling is seriously blocked, even leading to the extinction of the creature and breaking the sustainable development of the ecological environment. The creature tunnel design is provided. The utility model solves the problem of the creature traveling, and has no influence on the standard of dam storage or other standards. The utility model is characterized in that two valve doors of the upper reaches and lower reaches are designed, that is a double brake structure. Adopting the opening and closing method of crossing, and reasonable opening and closing time of crossing is determined; opening and closing time of crossing of the double valve doors is equal to the ratio of the creature cave length which divides the swimming speed of the creature; the creature can successful pass in the process of opening and closing of crossing of the double valve door; thus the hazard and the breakage of development and survival of the creature are avoided.

Description

Rivers dam biological corridor

Technical field

The utility model relates to the biological corridor on a kind of hydraulic structure rivers dam.

Background technology

At present, the rivers dam of being built is in the world just considered the human needs that oneself develop, and all not solve biological current problem when building, in the design of rivers dam, all is not designed to the biological biological corridor that passes through.The result blocks great rivers by the waist, and aquatile is current is obstructed to making, and has had a strong impact on and has destroyed biological existence and sustainable development, even caused species extinction, has greatly destroyed the diversity of ecological environment and species.At present, removed more than 500 on rivers dam all over the world, only more than 200 on dam is just removed by the U.S., and Maine State Ai Dewo reservoir had been removed by the U.S. in 1999, had recovered the survival and development of this river salmon.The Ge Zhou Ba of China, Three Gorges Dam all exist this problem.Particularly very serious to the influence of mandarin sturgeon, because the migration route of mandarin sturgeon has been blocked in the interception of dam, influence and destroyed the existence and the sustainable development of the biology of migrating, a large amount of mandarin sturgeons do not increase, and are tired out to death under the dam, this is not only biological tragedy, and Ren Lei something lost is shaken especially.The design of biological corridor proposes in order to address this problem just.

The utility model content

The purpose of this utility model be to provide a kind of on the rivers dam the current biological corridor that designs for biology.Promptly when the building of dam, design biological corridor, promptly do not influence other index of dam, biology is passed through, thereby avoided harm biology for passing through of biology.

The technical solution of the utility model is: the utility model rivers dam biological corridor, contain by the hole, the upstream and downstream gate, the upstream and downstream paddle hole, the upstream and downstream surge-chamber, wall lamp and watch-dog are formed, the section that the hole is contained can be designed to square or circular, the import department of containing in the hole establishes the upstream gate, the trip gate is set in the exit of containing in the hole, and gate all is designed to bulkhgead gate, and the both sides of the upstream gate of containing in the hole are provided with inlet opening and upstream surge-chamber, water hole and downstream surge-chamber are designed in the both sides of the lower gate of containing in the hole, in the sidewall that the hole is contained wall lamp and watch-dog are set.

The utility model biological corridor design upstream and downstream double-gate structure, and take the double-gate keying method of interlocking, determine reasonably staggered opening and closing time, staggered opening and closing time equals hole length divided by the general biological speed of moving about, thereby realized passing through smoothly of upstream and downstream biology, and do not influenced other index of dam.

The specific embodiment

The utility model rivers dam biological corridor, passage contains 1 by the hole, upstream gate 2, lower gate 3, inlet opening, upstream 4, downstream weep hole 5, upstream surge-chamber 6, downstream surge-chamber 7, wall lamp 8 and watch-dog 9 are formed.The hole is contained 1 section and can be designed to square or circularly all can, import department in hole culvert 1 establishes gate 2, and gate 3 is established in the exit of containing in the hole, and gate all is designed to bulkhgead gate, adopt up and down vertical lift or the plug-type keying of level all can, adopt the keying of computer program controlled double-gate.The both sides of containing 1 upstream gate 2 in the hole are provided with inlet opening 4 and upstream surge-chamber 6, in order to guarantee the hole contain in the microfluidic state of water body.Water hole 5 and downstream surge-chamber 7 are designed in the both sides of containing 1 exit gate 3 in the hole, in 1 sidewall is contained in the hole wall lamp 8 and watch-dog 9 are set, in order to illumination and the monitoring biological passage situation of hole in containing to be provided.

As shown in Figure 2,10. upper pond level, 11. dams, 12. levels of tail water are in, 13. rivers bottom lines.

The biological corridor that the utility model designs on the rivers dam, when downstream gate 3 is opened, the biological admission passage hole in downstream is contained in 1, biology upstream moves about along passage, when swimming to upstream gate 2, lower gate 3 cuts out, and upstream gate 2 is opened simultaneously, biology is swum out of the hole culvert, and trip is to the upstream of rivers.At this moment, the biology of upstream can enter the biological corridor hole again to be contained in 1, moves about downstream, and when swimming to lower gate 3 places, the gate 2 of upstream is closed, and the gate 3 in downstream is opened simultaneously, and biology just can be swum out of the culvert of passage hole, goes to the trip of the downstream of rivers.This has just finished the current process of a biology in passage, and the staggered keying that double-gate comes to this and moves in circles has realized biological passing through.

The biological corridor of the utility model rivers dam is applicable on the water conservancy project dam of building on the rivers and uses, and has solved biological current the biggest problem, has avoided influence and destruction to biology, has realized the ecological property structure design of water construction.
