The invention relates to a device for obtaining or collecting drinking water or tap water from ground (surface) water, can be used in the field of hydraulic engineering construction, and is intended for process (water supply) and technical (pump and other equipment) protection of water intake from falling sludge.

Successful struggle with the sludge on the water is possible only in case of special events. The most important measure against sludge is the use of filtering barriers, as included in the receiving water ice particles pass through a gravity or siphon pipelines to avankamera pumping station, causing freezing Korolevskaya grids, which leads water intake structure to the accident. Measures aimed at preventing freezing and driving the sludge filtration barriers play a special role in the successful operation of water supply systems.

The problem of freezing associated with thermal effects on the surfaces of the filter and particles of ice, i.e. solved at the molecular level. Therefore, an alternative modern composite polymeric materials in the manufacture spasaming filter barriers do not exist. The use of such materials in addition to high-tech processing methods of filtration material is the most acceptable is the first road against sludge on the water. The use of plastics for the manufacture of spasaming filter cartridges have the advantage that they have a high heat capacity, low thermal conductivity: the sludge is not premarket, they are durable: the reverse pulse flushing is not terrible for their sustainability, they are easy: installation and replacement do not cause big problems, they are cheap to manufacture and in operation.

The applicant is known the following analogs of the present invention.

Known protection device of water withdrawal from contact with sludge, consisting of filter tubes placed in a water bucket in front of the receiving water and connected to a compressor installation with air supply and creation before receiving water air / water veil (SU 1086063 And research Institute of water supply, Sewerage, waterworks and engineering hydrogeology, 15.12.1983, E 02 In 15/02).

The disadvantages of this device is that it, firstly, does not provide removal of sludge from water, and secondly, the costs of operation of the device is very high.

Known protection device of water withdrawal from contact with sludge, in which the pipe of larger diameter is tapered pipe with filter holes (US 3992886, Scott Robert A., 23.11.1976, E 02 In 13/00).

The disadvantage of this device is that it does not protect the intake from the falling of sludge high flow water usage.

Known protection device of water withdrawal from contact with sludge, consisting of located at the bottom of the watercourse complex system of filters provides consistent filtration of water before supply to the pump station (EN 2124610 C1, Institute of water supply, Sewerage, waterworks and engineering hydrogeology, 10.01.1999, E 03 In 3/04).

Disadvantages counterpart is that the device quickly becomes clogged with sludge and sediment.

Known protection device of water withdrawal from contact with sludge, consisting of a volume of the filter cartridge, which represents a reinforced concrete slab inserted in the slots on the inner side of the metal rectangular contour of the frame that is installed in the guide groove design input window flooded intake end of the intake (Obrazovky A.S., Erenow NV, Erenow V.N., Kazan M.A. intakes for water supply from surface sources. Stroiizdat, 1976. With 210).

Disadvantages counterpart is that the device can be easily clogged with sludge, unreliable in operation (when using the reverse pulse wash easily destroyed in the weakest places with holes), it is extremely difficult to manufacture and has a large weight in running order.

Closest to the invention together being the different signs is a protection device intakes from contact with sludge, containing large filter cartridge consisting of tightly installed in a metal rectangular contour frame with grooves on the inner side of the filtering plastic pipes (protection Device intakes from falling sludge: Per. No. 20000126572/13/ Ammation, ARB, Whishaw, NN. Sidorov. - 2182619; Appl. 24.10.2000; Publ. 20.05.02. - BIPM No. 14(11 o'clock). - S. 249).

The disadvantages of the prototype is that the device has a greater thickness (manufactured filter plastic pipes have a large outer diameter) to fit into the guide groove design input window typical flooded intake end of the intake. In addition, through the cracks between the filtering plastic pipe is dripping water relative to the costs, which leads to an increase of the flow velocity in front of the entrance Windows of the receiving water intakes and reduce the effect of sugoshita.

FIELD: hydraulic engineering; fish protective facilities.

SUBSTANCE: invention is designed to draw off young fish from zone of influence of water diversion front. Method comes to ejecting young fish into intake part of ejecting plant from section of pond with higher concentration of young fish, creating active ejecting working stream in mixing chamber by entraining volume of water containing young fish into stream created by central ejecting hydraulic jet and further conveyance of water-fish mixture along pressure conduit into fish outlet. At the last stage of conveyance young fish is transported into fish outlet under no pressure conditions by forming hydraulic jet angle to trough of fish outlet, young fish being dropped on surface of fish outlet stream. Invention provides effective conditions for drawing off young fish into fish outlet and reduces damage to young fish. If working ejecting stream is preliminarily saturated with atmospheric air, its outer borders are saturated with air in form of finest microbubbles which form boundary layer ("air cushion") at contact with which young fish do not suffer from discomfort and easily take up hydrodynamic pressure built in mixing chamber. Moreover, provision of boundary layer saturated with microbubbles of air makes it possible to considerably reduce value of friction coupling of two streams, main getting from working nozzle and ejecting, containing young fish.
