The invention relates to hydraulic engineering, in particular to fish passages included in the composition of the hydrosystem.

The purpose of the invention is to increase work efficiency by eliminating the fish in the opposite direction through the slots of the working gates.

FIG. 1 depicts a fish gateway plan; in fig. 2 is the same, section A-A in FIG. one; in fig. 3 - section BB

Cranks 18 are hingedly connected by connecting rods 25.

The fish gateway works in the following way.

To force the fish to move by means of an incentive device 10 from the fish storage tray 2 into the working chamber 3, the downstream shutter 8 is raised upwards. In this case, the rollers 23 of the upper cranks 16 rotate, due to the interaction of the normal operation of the cranks, due to the interaction of the alarm device 10, made in the JQ of the side faces of the movable shutter 8 in the form of the netting AND, and installed with the rollers 23 pressed against the counterweight 20. the seizure of the rollers 23, as well as if foreign objects get into the gap between the shield 13 and the lateral face of the bolt 8, which later contain a vertical shield 13, 25 will slit relatively ro- located with the possibility of emesche-faces 23. In this case, the probability zaklinini in the groove 5 or 6 working gates 7, 8 between 8vani shutter 13 shields (rasparallelno its longitudinal wall 14 gib-position on either side of the shutter 8)

excluded due to the fact that the forces transmitted from the bolt 8 to the shields 13 when it is raised will turn the cranks 18 towards the wall 14 of the groove 6, pushing the shields 13 in the same direction. After the release of the bolt 8 from the groove 6, the counterweight 20, lowering it to the stop 24, expands the cranks 18, moving

The fish gateway includes a horse output tray 1, a fish collection tray 2, a working chamber 3 with 4 vertical slots 5, 6 in which 4 are mounted, the upper 7 and the lower 8 can be moved in the vertical plane, the ichthyological site 9, the pos the ability to move along the fisheries1) H1Sitioiog () of tray 2 and); | barrel 3, devices 12 for closing grooves 5, 6 working gates 7, 8 each of

At this time, the seams 13 are raised and the flexible plates 15 are straightened, closing the gap between the shield 13 and the bottom of the lotus axis with the possibility of interaction between 1 and 40 ka of the working chamber 3. Rods 25 The mechanism with the side face of the working gate / or 8 ,, and the stop 24, rigidly mounted on the outer surface of the station 4 working chamber under the counterweight 20 with the possibility of a P1 hinge parallelogram prevent the possibility of its turning into an anti-parallelogram mechanism in the extreme position.

After moving the fish into the working chamber 3, the lower-5Q shutter 8 is lowered down. At the same time, it comes into interaction with the rollers 23, turning the cranks 18 and folding the seams 13 into the grooves 6 of the bolt 8 Burned between the longitudinal walls 14 pins of 20 11) and this lifts over call 5, 6 and upper hinges 19. cup 24, preparing the device for; In addition, the section of the flexible yoke 21.55 of overlapping grooves 5, 6 in the next cycle is connected with one of the cranks 18, lu.

At this time, the seams 13 are raised and the flexible plates 15 are spread out, closing the gap between the shield 13 and the bottom of the tray of the working chamber 3. The rods 25 are machined through the grooves 6 of the bolt 8 or accumulation fish in grooves excluded. After the fish is moved into the working chamber 3, the lower shutter 8 is lowered down. At the same time, he comes to interact with the rollers 23, unwrapping the cranks 18 and folding the seams 13 into the grooves 6 of the bolt 8 (Progoshno 20 11) and rises above the stop 24, preparing the device to close the grooves 5, 6 in the next cycle. The transfer of fish from working chamber 3 to horse tray 1 is carried out similarly to transfer to working chamber 3.
