Abstract

The invention relates to hydraulic engineering, in particular, to river intake structures. The purpose of the invention is to increase the effectiveness of protecting fish from falling into a diversion channel and reducing sediment input. The water intake structure consists of a barrier panel 1 with surface 2 and depth 3 floats attached to the bottom by braces 10, anchors 11 and t 12 and rotary panels 5 with floats 6 and ballasts 8 attached by hinges 4 to float 3. Cloths 5 connections 9 and 13 t through 13 blocks of piles 15 are connected to traction devices. The structure is installed at the entrance to the diversion canal parallel to the river bank. Depending on whether the fish goes to spawn or fish slope occurs along the river, they turn in plan of panels 5, maneuver with traction devices with flexible rods 13. Setting panels 5 at an angle to the flow of water in the river ensures deflection of fish and sediments. In the middle of the river, clear water flows into the diversion canal through window 18. 1 hp f-ly, 5 ill.

Description

FIELD OF THE INVENTION The invention relates to hydraulic engineering, namely to river intake structures.

The purpose of the invention is to increase the efficiency of protection of fish from falling into the outgoing channel and reducing sediment input.

FIG. 1 shows a water intake structure, axonometrics; figure 2 is the same cross section; FIGS. 3-5 are constructions at different positions of the rotary panels, top view.

The water intake structure consists of a flexible barrier panel 1 with a surface float 2 attached to its upper edge and a deep float 3 attached to its lower edge. A system of additional walkway panels 5 with floats b attached to the upper edge of the panels 5 is attached to the front part of the deep float with 3 hinges 4. Pockets 7 made of heavy material forming the ballasts 8 are made at the lower edge of the panels 5 The sheets 5 are interconnected by flexible connections 9. The depth float 3 of the panel 1 is kept in suspension by the braces 10 to the bottom anchors 11. The float 2 is fixed in position with the tips 12. The outer panels 5 are connected by flexible pipes 13 and a block 14, pivotally mounted on vertical piles x 15, with traction devices (not shown) that allow control of the position in terms of the panels 5 relative to the water intake front. Rotation of the floats 6 with panels 5 on the hinges 4 is possible both in one and in the other direction at an angle of 0-180 by moving tg 13 through blocks 14 on the pile 15, immersed in the bottom of the reservoir along the hinges 4 (in the panel 1 ). The structure is installed parallel to the bank of the river 16 at the entrance to the diversion channel 17 to form a bottom water intake window 18.

During the mass migration of fish to spawn on the river 16, the system of movable panels 5 using one of the traction devices and weakened the other is set at an angle (o6, Ј90 °) relative to the front of window 18. This position of the panels 5 prevents the fish from actively rising up the relay 16, out the window 18.

When the mass slope of fish and during the low flow period, the system of panels 5 is set in the same way at an angle (). The flow of the river 16 takes the fish downstream without sucking it into the window 18. The position of the panels is adjusted so that the flow rate of water at the entrance to the window 18 is 3-5 times lower than the transit flow rate of water in the river 16. The closing of the window 18 is carried out by tensioning one of the flexible tg g 13 t stew device. With the water intake window 18 completely blocked, it is possible to draw water from the upper layers of the stream of the river 16, for which it is necessary to lower the panel 1 by filling the surface float 2 with water.
