Middle fixation, and fish inlet (7) is arranged in different water depth or different fishponds or different running water stable breeding regions, so that migration
Fish can swim out of from specified region, convenient for the progress of fish culture work；
Step4: the export of fish, the fingerling and fish size that different water depth is inhabited are carried out when reservoir liquid level reduces or increases
It is all different, fixed point is exported by straddling fish stocks by the fish inlet (7) of different liquid levels, the fish for avoiding rigid migration from passing through are big by deep water
Figure fish swallow；
Step5: after liquid level reduces, being arranged at fish inlet (7) position of shallow water area originally has dry possibility, at this time then
Straddling fish stocks are all exported from the deep water level fish inlet (7) of the other side；
Step6: when liquid level changes, it is off-state, liquid level sensor switch that liquid level sensor switchs (15) originally
(15) if being located at the water surface or more, liquid level sensor switchs (15) closure, switchs (15) concatenated police with liquid level sensor at this time
Show that lamp (16) are lighted by junction block (12) power supply, warning lamp (16) is drawn out to control room, and administrative staff may know that liquid at this time
Position is too low, should not export straddling fish stocks from this fish inlet (7), then control steering cylinder (20) movement, steering cylinder (20)
Piston rod (25) stretch out, then the turning-bar (19) hinged with piston rod (25) drives pin shaft (17) rotation, then restriction plate (18)
It rotates with it, after the end of restriction plate (18) is contacted with limit switch (21), then limit switch (21) is touched, steering oil
Cylinder (20) stops expanding-contracting action, and under the barrier effect of restriction plate (18), the transfer square tube (5) of side is plugged, straddling fish stocks
It can only be swum out of from the transfer square tube (5) of the other side, thereby realize the migration direction controlling of straddling fish stocks.
