Description
Technical field
The utility model is related to hydraulic engineering field, more particularly to a kind of vertical seam type fish channel structure.
Background technology
Influence of the Hydraulic and Hydro-Power Engineering to ecological environment is especially big, and the migration of fish, heavy damage can be blocked by building dam
The ecological environment in river.Currently in order to solving this problem, it is accustomed to according to the migration of fish, one can be built in the vicinity of dam
Bar is adapted to the fish pass of fish migration；Fish are sailed against the current by fish pass.
Existing fish pass, because current are more rapid, fish are more tired during migration, understand due to being short of physical strength,
Trip is not got on；In order to solve the problem, rest pond is provided with some fish pass, due to existing rest pond, structure is more complicated,
The current for coming and going or circulating can be produced, easily fish is got lost, causes the failure of migration.
Utility model content
The utility model provides a kind of vertical seam type fish channel structure, it is intended to solve in the prior art because current are more rapid
Anxious, fish can cause the problem of migration fails during migration due to being short of physical strength.
In order to solve the above technical problems, the utility model is achieved through the following technical solutions：
A kind of vertical seam type fish channel structure, including U-lag and several rest ponds being arranged in U-lag body；U-lag is the bottom of by
Plate and the biside plate composition perpendicular to bottom plate；Rest pond is tubaeform, the rest pond surrounded by two dividing plates perpendicular to bottom plate
The small one end of opening is for water inlet and towards the upstream region of U-type groove, and opening big one end in rest pond is delivery port and towards U-shaped
The downstream area of groove；The width at the most narrow place in one number service road that each dividing plate is constituted with adjacent side plate is all higher than the water inlet in rest pond
The width of mouth.
Further, dividing plate is the arc to rest pond outer projection.
Further, rest board of the dividing plate madial wall provided with the extension of downstream region.Fish can be hidden in rest board
Rear side, reduces the impact of current, is rested.
Further, the upper end of rest board, which is located at, is less than the water surface.Rest board can be made still there are current to pass through, prevented because of baffle plate
Effect produce recirculated water, it is ensured that the direction of current, fish is not got lost, be easy to sail against the current.
Further, bottom plate is provided with baffle plate, and baffle plate is located at the water inlet upstream region in rest pond and entering close to rest pond
The mouth of a river is set.It can stop that current are flowed directly into rest pond, reduce the water velocity in rest pond.
Further, baffle plate is provided with limbers, and limbers is taper, and limbers water inlet end is small and water side is big.By logical
The water of water hole outflow can ensure that the direction of current is not disturbed by baffle plate, make fish be not easy to get lost.Limbers intakes
End is small and water side is big；On the one hand the water velocity flowed out from water side can be slowed down, prevent current from concentrating ejection；The opposing party
Face, can prevent the accumulation in impurity limbers.
Further, guide plate is equipped with biside plate, No. two passages towards side plate are formed between guide plate and baffle plate.Two
Number passage can guide current to one number service road, it is possible to reduce current enter in rest pond, slow down the water in rest pond
Flow velocity degree.
Compared with prior art the utility model has the advantages that：
The utility model includes U-lag and several rest ponds, and in rest pond, fish can sufficiently be rested.
Rest pond be by two dividing plates perpendicular to bottom plate surround it is tubaeform, the small one end of rest pond opening be water inlet
And towards the upstream region of U-type groove, opening big one end in rest pond is delivery port and towards the downstream area of U-type groove；Due to stopping
The water inlet for ceasing pond is small, and big inside rest pond, then rest pool inner water stream can slow down, and can have larger resting space to fish,
Fish are made to advance under sluggish flow.
The width at the most narrow place in one number service road that each dividing plate is constituted with adjacent side plate is all higher than the water inlet in rest pond
Width；The inflow in rest pond can be made less than the inflow in two one number service roads, the water velocity in rest pond is slow down.
Brief description of the drawings
In order to illustrate more clearly of the technical scheme of the utility model embodiment, it will use below required in embodiment
Accompanying drawing be briefly described, it will be appreciated that the following drawings illustrate only some embodiments of the present utility model, therefore should not see
