Specific embodiment
Embodiment 1: as shown in Figure 1, formula crosses fish device, including upper gate 1, middle part gate 2, aft-gate behind a kind of dam
3, fish pipeline 4, anchor block 5, buttress 6, first layer casing 7, second layer casing 8, downstream collection fishpond 10 are crossed；The first layer casing 7
It is arranged above dam body 13, first layer casing 7 is connected to 13 dam facing position of dam body equipped with buttress 6, and the top of first layer casing 7 is set
Fish pipeline 4 was set, the inside of fish pipeline 4 was arranged in second layer casing 8, and downstream collection fishpond 10 is arranged in entering for aft-gate 3
Water end (W.E.), the upstream water inlet for crossing fish pipeline 4 and first layer casing 7 are arranged upper gate 1, cross fish pipeline 4 and first layer casing 7
Middle part setting middle part gate 2, aft-gate 3, middle part lock is arranged in the downstream water outlet for crossing fish pipeline 4 and first layer casing 7
Door 2 and downstream collection fishpond 10 are connected to second layer casing 8, and anchor block 5, downstream fish gathering are equipped between upper gate 1 and middle part gate 2
Pond 10 is equipped with anchor block 5；First layer casing 7,8 pipe diameter of second layer casing are less than the width of fish.
Further include the adjustable collection fishpond 9 in upstream it is possible to further be arranged, the adjustable collection fishpond 9 in upstream be arranged pin thread with
Female thread connection on dam body 13.
It is possible to further the adjustable collection fishpond 9 in the upstream, downstream collection fishpond 10 being arranged using ventilative reticular structure and
Equipped with lid；The lid in the adjustable collection fishpond 9 of its middle and upper reaches is located at close to 13 side of dam body, and the lid in downstream collection fishpond 10 is located at
Top surface.
Formula crosses the application method of fish device behind a kind of dam,
Fish swim over to upstream from down:
Upper gate 1, middle part gate 2 are closed, and aft-gate 3 is opened, and water level is flushed with the level of tail water in downstream collection fishpond 10, are lured
It leads fish and enters downstream collection fishpond 10(according to the habit of the phototaxis of fish and hobby adverse current, utilize light, water flow and bait etc.
Method induces fish；Or use conventionally known ultrasonic wave fish-baiting instrument, fish-luring light etc.)；Fish close downstream lock after entering
Door 3, open middle part gate 2 in second layer casing 8 position, make middle part 2 upstream face of gate stop water flow (i.e. upper gate 1,
When middle part gate 2 is closed, the water that fish channel 4 is retained is crossed) downstream collection fishpond 10 is entered by second layer casing 8, then all beat
Middle part gate 2 is opened, the water flow that gate 2 upstream face in middle part stops can pass through fish pipeline 4 and second layer casing 8 enters downstream jointly
Collect fishpond 10, then opens upper gate 1 to 7 position of first layer casing, upper water stream flows into downstream by first layer casing 7
Collection fishpond 10(incremental mode, which is realized, avoided fish pipeline 4, first layer casing 7, second layer casing 8 too fast due to washing by water
Lead to pipeline damage)；Water in downstream collection fishpond 10 can flow into fish pipeline 4, served as water level in fish pipeline 4 gradually rise to
After upstream water level flushes, upper gate 1 is fully opened, fish pipeline 4, first layer casing 7 excessively is connected to upper water, fish are induced,
Swimming it, (the adjustable collection fishpond 9 in setting upstream may be implemented fish and collect, while can into the adjustable collection fishpond 9 in upstream or upstream
It is used to swim into downstream etc. so that demand fish are put into the adjustable collection fishpond 9 in upstream)；Finally, closing upper gate 1 and middle part gate
2, aft-gate 3 is opened, the operation in next period is carried out；It opens and lid closes the adjustable lid for collecting fishpond 9 of trip and realizes fish
Entrance and storage；
Fish are from upstream to downstream:
Middle part gate 2 is opened, and upper gate 1, aft-gate 3 are closed, and is then opened upper gate 1 and is arrived 7 position of first layer casing,
Enter upstream water in pipeline by first layer casing 7 and be gradually filled with fish pipeline 4, then fully opens upper gate 1,
After upstream fish enter upper gate 1, upper gate 1 is closed, fish, which are swum to downstream collection fishpond 10 or opening aft-gate 3, to be made
Fish, which are swum out of, reaches downstream；Last middle part gate 2 is opened, and upper gate 1, aft-gate 3 are closed, and carries out the fortune in next period
Row；Open and cover the entrance and storage for closing the lid realization fish in downstream collection fishpond 10.
Wherein, when upstream water level position is located between the top and bottom for crossing fish pipeline 4 on dam crest, effect is more excellent.
Above in conjunction with attached drawing, the embodiment of the present invention is explained in detail, but the present invention is not limited to above-mentioned
Embodiment within the knowledge of a person skilled in the art can also be before not departing from present inventive concept
Put that various changes can be made.
