Abstract

The invention relates to hydraulic engineering, in particular, to devices for passing migratory fish from one bay to another. The purpose of the invention is to increase work efficiency. Fish are attracted to the fish tank 2 when the bottom 7 of the working chamber 1 is horizontal, and the water is supplied through the culvert 5 of the front wall 4. The additional waterproof wall 19 prevents water from discharging above the bottom hole 20 and ensures normal hydraulic operation in the working chamber 1 and the fish accumulator 2. As the fish accumulates, the working chamber 1 rotates around the hinge 18, its upper end lowers into the recess 17, and the lower end rises above the water level of the upper efa 22. Thus there is a locking fish and its output to the output tray 3 over the additional wall 19. In order to ensure continuity of the storage of fish through sluice openings 9 in rybonakopitel 2 supplied water flow needed to create attracting plume. The fish retaining grill 12 blocks the fish from entering the zone of the working chamber 1, preventing injury to the fish. After the fish leaves the working chamber 1 into the output tray 3, the latter turns around the hinge 18 in the opposite direction and a new cycle of the gateway begins. 1 il.

(54) FISHING GATEWAY (57) The invention relates to hydraulic engineering, and in particular, to devices for passing migrating fish from one pool to another. The purpose of the invention is to increase work efficiency. Attracting fish to the fish tank 2 is carried out with the horizontal position of the bottom 7 of the working chamber 1, while the water is supplied through the culverts 5 of the front wall 4. An additional waterproof wall 19 prevents the discharge of water above the level of the lower pool 20 and ensures normal hydraulic mode in the working chamber 1 and fish feeder 2. As the fish accumulate, the working chamber G rotates around the hinge 18, its upper end descends into the recess 17, and the lower end rises above the water level of the upper b port 22. In this case, the fish locks and exits into the output tray 3 above the additional wall 19. To ensure the continuous accumulation of fish through the culverts 9, the flow rate necessary for creating an attracting plume is supplied to the fish tank 2. Q Fish-retaining grill 12 blocks the fish from entering the area of the working chamber 1, preventing injury to the fish. After the fish leaves the working chamber 1 in the output tray 3, the latter rotates around the hinge 18 in the opposite direction and begins a new cycle of the gateway. 1 ill.

The invention 'relates to hydraulic engineering, and in particular to devices for passing migrating fish from one pool of a hydraulic system to another.

The aim of the invention is to increase work efficiency.

The drawing shows a longitudinal section of a fish gateway. I The fish gateway includes a working chamber 1, in which a fish collector 2 is adjacent from the bottom side, and an output tray 3. The working chamber 1 includes a front wall 4 made along an arc of a circle, with culvert holes 5 and a spillway visor 6, bottom 7, the lower end . 8 of which is equipped with a culvert 9, and side walls 10. A fish-holding lattice 12 is attached to the grill 9 using a hinge 11, the other end of which is connected to the base 13 by means of hinges 14 moving in the longitudinal grooves 15. The base 16 of the working chamber 1 is made with a wedge-shaped recess 17. The working chamber 1 is connected to the 'base 16 by means of a hinge '18.

In front of the front wall 4 of the working chamber 1, an additional waterproof wall 19 is installed, made along an arc of a circle, its lower part is flooded under the level of the lower pool 20, forming an opening 21.

Fish gateway operates as follows.

Attracting fish to the fish tank 2 is carried out at such a position of the working chamber 1, when its bottom 7 is horizontal, due to the supply for this purpose of water through the hole 21 and the culvert holes 5 of the front wall 4. To ensure normal! hydraulic mode in the working chamber 1 and fish hatcher 2 additional waterproof wall. 19 prevents the discharge of water into the atmosphere above the water level of the downstream 20.

After a period of attraction, when a certain number of migratory fish has been accumulated, the working chamber 1 rotates (the drive is not shown; around the hinge 18 so that its upper end together with the front wall 4 lowers into the recess 17 and the lower end rises above the water level of the upper pool 22 in this case, the fish locks and exits' into the output tray 3 above the additional wall 19. 5 In order to ensure the continuous accumulation of fish, the water flow necessary for creating Ia attracting plume. At 10 this to avoid possible injury to fish rybozaderzhivayuschaya grating 12 at this time blocks the path of the fish in the working zone of the chamber 1.

After the fish exit the working chamber 1 to the output tray 3, the latter rotates around the hinge 18 in the opposite direction and a new cycle of the gateway starts.

This fish access device allows you to abandon the use of locks in locks, provides a continuous cycle of attracting fish and a smooth transition from attraction. to lock fish, which ultimately __ j account allows to increase work efficiency and reduce the cost of construction and operation of fish passage facilities.

Claims (1)
