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.
The use process of the utility model is:
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 and the level of tail water are neat in downstream collection fishpond 10
Flat, induction fish enter downstream collection fishpond 10(according to the habit of the phototaxis of fish and hobby adverse current, using light, water flow and
The methods of bait induces fish；Or use conventionally known ultrasonic wave fish-baiting instrument, fish-luring light etc.)；Fish are closed after entering
Aft-gate 3 opens the position of second layer casing 8 in the gate 2 of middle part, water flow (the i.e. upstream for stopping middle part 2 upstream face of gate
When gate 1, middle part gate 2 are closed, the water that fish channel 4 is retained is crossed) downstream collection fishpond 10 is entered by second layer casing 8, then
Fully open middle part gate 2,2 upstream face of middle part gate stop water flow can pass through fish pipeline 4 and second layer casing 8 jointly into
Enter downstream collection fishpond 10, then opens upper gate 1 to 7 position of first layer casing, upper water stream is flowed by first layer casing 7
Enter the incremental mode of downstream collection fishpond 10(realize avoided fish pipeline 4, first layer casing 7, second layer casing 8 due to punching
Water is too fast to lead to pipeline damage)；Water in downstream collection fishpond 10 can flow into fish pipeline 4, served as in fish pipeline 4 water level gradually on
It is raised to after being flushed with upstream water level, fully opens upper gate 1, cross fish pipeline 4, first layer casing 7 is connected to upper water, induction
Fish, swimming it, (the adjustable collection fishpond 9 in setting upstream may be implemented fish and collect, together into the adjustable collection fishpond 9 in upstream or upstream
When demand fish can be put into the adjustable collection fishpond 9 in upstream be used to swim into downstream etc.)；Finally, closing upper gate 1 and middle part
Gate 2 opens aft-gate 3, carries out the operation in next period；It opens and lid closes the adjustable lid for collecting fishpond 9 of trip and realizes
The entrance and storage of fish；
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 first layer casing 7
Position enters upstream water in pipeline by first layer casing 7 and was gradually filled with fish pipeline 4, then fully opens upstream
Gate 1 after upstream fish enter upper gate 1, closes upper gate 1, and fish swim to downstream collection fishpond 10 or open downstream
Gate 3 makes fish swim out of arrival downstream；Last middle part gate 2 is opened, and upper gate 1, aft-gate 3 are closed, and carries out next week
The operation of phase；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.
The specific embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the utility model is not
Be limited to above embodiment, within the knowledge of a person skilled in the art, can also do not depart from it is practical
Various changes can be made under the premise of novel objective.
