Abstract

The invention relates to hydraulic engineering and is intended for water intake and destruction of silt deposits and colonies of higher algae along the generatrix (bottom) of the irrigation canal. The purpose of the invention is to expand the functionality of a water intake device by preventing algae from sticking to the surface of the filter element. The presence of an inkjet block in the intake device

Description

nozzles 9, which are connected through an operator-controlled valve 10 to the pressure port of the pump and dispersal are installed in the zone of operation of the filter element 2 with the possibility of changing the height and angle of installation in the vertical plane provides the maximum efficiency of destruction of silt deposits of colonies of higher algae along the generatrix (bottom) of the irrigation channel. In is, I -. -.- -

in the running position, the filter element 2 is at a height H relative to the bottom of the channel, and the nozzle block is at a height h relative to the surface of the sludge deposits, the nozzles themselves are at an appropriate angle

2 ° to the generatrix (bottom) of the irrigation canal, providing maximum destruction efficiency of silt deposits and colonies of higher algae. 2 ill.

The invention relates to agriculture and can be used, for example, on sprinklers powered by open irrigation canals.

The purpose of the invention is to expand the functionality of a water intake device.

Figure 1 schematically shows a water intake device, rear view; figure 2 is the same side view.

The device includes a pump (not shown) with a suction 1 and pressure (not shown) nozzles, a filter element 2 in the form of a rotating drum from a sheet of corrosion-resistant material with holes of the corresponding diameter, equipped with a drive 3, a discharge tray 4, a scraper 5, a flushing flute 6 connected to the discharge pipe by a pipe 7 through an automatic valve 8. The jet nozzle unit 9 is also connected to the pressure pipe of the machine through an operator-controlled valve 10. The nozzles are dispersedly installed in the area of operation of the filter element 2 with the possibility of changing the height and installation angle o ° in the vertical plane, taking into account the maximum efficiency of destruction of silt deposits 11 and colonies of higher algae 12 along the generatrix (bottom) of the irrigation channel 13. Number of nozzles and their location are determined by the profile of the canal, the degree of its contamination, the type of weed vegetation, etc. To change the location of the block of jet nozzles 9 directly relative to the bottom of the channel and the filter element 2 as a whole, a adjustment and fixing device 14 is used. To supply the filtrate from the surface of the filter element 2 to the accumulator 4, a ejector 15 is used, operating from a common drive 3.

In the initial position, the filter element 2 is located at a height H relative to the bottom of the channel 13, and the block of jet nozzles 9 is generally located, taking into account specific conditions, at a height h relative to the surface of the sludge deposits 11, while the nozzles 9 themselves are under the corresponding

angle of ° to the generatrix (bottom) of the irrigation canal 13, which ensures maximum destruction efficiency of silt deposits and colonies of higher algae.

During operation of the sprinkler in normal mode, i.e. when there is a predominantly floating debris in the channel, water through the holes and the cavity of the rotating (using the drive 3 of the filter element 2), the suction pipe 1 is pumped (shown by an arrow) into the discharge pipe and then through the pipelines to the nozzles

sprinkler machine. At the same time, water is supplied through the automatic valve 8 to the cleaning of the filter element 2 with a flute 6. If, in the irrigation channel, 13 sludge deposits 11 are in sufficient quantity and higher algae colonies 12 are fixed in them by the roots, the operator additionally switches on manually or remotely using the controlled valve 10 directly to the jet nozzle block 9 into operation. Pressure outlet of nozzles 9 under

a given angle (f to the generatrix (bottom) of the irrigation channel 13, water jets

mud sediments 11 are agitated, algae 12 are inaccessible to them, and already in suspension, particles of silt and algae enter the holes of filter element 2. Moreover, they are rather small

particles pass through the holes and together with water fall onto the irrigated field (used as organic fertilizer), larger ones (stuck in cells) are cut off with a scraper 5 and washed off with

floating debris, for example, due to a hydraulic slope, and is also fed by the ejector 15 to the accumulator 4.
