Description

The invention relates to hydraulic structures, namely to water intake structures, which provide water for the abstraction of water by the user taking into account the requirements of protection of the environment and respect for the quality characteristics of the water taken.

The purpose of the invention is to increase the quality of the abstracted water, to preserve the flora and fauna of the reservoir by providing the possibility of changing the angle of entry of the water flow into the water reservoir:

The drawing shows the proposed water intake structure at different positions of the water intake window, a transverse section.

Water intake includes an upper movable panel 1 with a surface float 2 attached to its upper edge, having a loop 3 sagging with stabilizing ballast 4, and a lower panel 5 interconnected by a deep float 6 fixed by a brace 7 to an anchor 8 located on bottom of the reservoir.

The water intake structure is also provided with an additional bottom movable panel 9, a bottom anchor 10 with a block 11 attached to it and a bark 12 located on the water side, additional depth floats 13 and 14 interconnected by a rigid link 15 of a length equal to the height of the intake window 16, traction device 17 and flexible connections 18,19 and 20 ..

An additional deep float 13 is attached to the upper edge of the bottom panel 9 and connected by a flexible LINK 18 passing through the block 11 to a traction device 17, for example a winch, and an additional deep float 14 is attached to the free edge of the lower panel 5 and connected by a flexible link 19 with the surface float 2, and with the bark 12 - a flexible bond 20. Bending bond. 18 changes its length due to the operation of the traction device 17 and the submerged float 13. The bottom panel 9 is fastened to the bottom anchor 10 with the lower edge.

Water intake works in the following way ..

The flow of water, the approach to the water intake structure, meets on its way an additional bottom panel 9, the shape and location of which

create along it slowly rotating. spiral roller directed along additional panel 9. Formed water drum

keeps in its volume the representatives of flora and fauna living in the lower layers of the reservoir. The upper layers of the water flow are directed to the water intake, which are additional

The bottom panel 9 with the submerged float 13 is redistributed to the whole. the depth of the reservoir, the lower part of this layer, free from the living ichthyofauna and plankton, passes into the water intake window 16. The upper layers of water, along with representatives of flora and fauna that inhabit the upper layers of the reservoir, enter the space bounded by the upper

movable panel 1 and. the bottom panel 5,. and form a flow of water with a spiral motion, which carries representatives of the ichthyofauna and plankton beyond

water intake facility. The water flow is divided cascade vertically and into the water intake window 16 passes cleared of debris and inhabitants of the reservoir. ..

„

Depending on the speed of movement of the water flow and its flow, the intake window 16 changes its position in space. This is achieved by varying the angle of the link 15. by adjusting the float of the submerged float 13 and changing the length of the flexible link 18 with the help of a traction device 17 mounted on the shore or on the pontoon.

By changing the angle of inclination of the link 15 between the submerged floats 13 and 14 of the bottom panel 9 and the bottom panel 5, the angle of flow of water into the water intake window changes. 16, ensuring optimum water quality.

Such a water intake structure without special waste and cleaning devices eliminates the possibility of various debris and representatives of ichthyofauna and plankton of the reservoir entering the grids of the water intake, which usually accumulate in front of the iodine intake.

The proposed water intake construction; Ensuring allows for optimum.

the quality of abstracted water and the soils that dwell in the midst of the movement of all animal species are dykes and are unable to resist plants and vegetational organisms over the course of time.
