Description
Technical field
the utility model relates to a kind of vertical seam type fish channel, belongs to ecological protection technical field in Hydraulic and Hydro-Power Engineering.
Background technology
when building dam, in order to the migration passage preventing dam from stopping fish, requirement must build fish pass structure.Cross fish passage can be divided into diaphragm plate type fish pass, primary stance fish pass, slot type fish pass and special structure form fish pass etc. by its structural shape and hydraulic characteristic.Diaphragm plate type fish pass can be divided into overflow weir formula by dividing plate pattern, floods outlet type, vertical seam type, combined type.Modal form of structure according to the feature of domestic water electrical engineering and the characteristic vertical seam type fish channel of straddling fish stocks.Typical vertical seam type fish channel comprises fish pass abutment wall, guide plate and dividing plate, by guide plate and dividing plate, fish pass is divided into room, multiple pond, guide plate and dividing plate are oppositely arranged, and are reserved with room, pond perps between guide plate and dividing plate, pond is interconnected by perps between room, and fish are sailed against the current by room, pond perps.A upper pond indoor water flows through after perps enters room, next pond, and current encounter guide plate, dividing plate forms recirculating zone, with current blending below, play the effect of energy dissipating, reduce the flow velocity of current, thus the resistance that reduction straddling fish stocks are subject to, make fish easierly can pass fish pass.But find in actual use; current in the room, pond of existing vertical seam type fish channel do not obtain abundant blending; effect of energy dissipation is poor; cause perps place flow rate of water flow larger; the resistance that the fish of migration are subject to is larger; cause fish to pass fish pass difficulty to increase; and then fish will reduce through the quantity of fish pass; make the impact of water power hydraulic engineering on fish migration larger; be unfavorable for the ecological protection in river; and the turning of existing clapboard end is right angle, fish are being easily subject to mechanical injuries by during the perps of room, pond.
Utility model content
the purpose of this utility model is, provides a kind of vertical seam type fish channel.The abundant blending of current can be made, improve effect of energy dissipation, reduce perps place flow rate of water flow; reduce the resistance that the fish of migration are subject to, make fish pass fish pass and be more prone to, and then fish will increase through the quantity of fish pass; improve fish effect, be conducive to the ecological protection in river.
the technical solution of the utility model:
a kind of vertical seam type fish channel, comprises twice fish pass abutment wall; Be provided with one group of guide plate inside fish pass abutment wall on one side, inside the fish pass abutment wall of another side, be provided with one group of dividing plate; Guide plate and dividing plate are arranged in pairs, are divided into room, multiple pond along vertical seam type fish channel length direction; Perps is provided with between guide plate and dividing plate; Described guide plate and dividing plate shift to install.
in aforementioned vertical seam type fish channel, described guide plate and the dividing plate 300mm that misplaces is arranged.
in aforementioned vertical seam type fish channel, room, described pond width W is 7 times of perps width B, and room, pond length L is 8 times of room, pond perps width B.
in aforementioned vertical seam type fish channel, described guide plate length is 3/4 of room, pond width W, and septum plate length is 1/4 of room, pond width W.
in aforementioned vertical seam type fish channel, described perps two sides and the angle α between guide plate and dividing plate downstream face are 40 ~ 50 degree; Perps two sides and the angle β between guide plate and dividing plate end face are 60 ~ 70 degree.
in aforementioned vertical seam type fish channel, described perps two sides and the angle α between guide plate and dividing plate downstream face are 45 degree; Perps two sides and the angle β between guide plate and dividing plate end face are 63 degree.
compared with prior art, the utility model can make the abundant blending of current in fish pass, improves effect of energy dissipation; reduce perps place flow rate of water flow, the resistance that the fish reducing migration are subject to, make fish pass fish pass and be more prone to; improve fish quantity and effect, be conducive to the ecological protection in river.
