The invention relates to hydraulic engineering and can be used for purification of water from the fins and sediment flowing into the pipes irrigation equipment.
Known outlet of the channel, including the water intake hole made in the bottom of the channel, a grid and a shield with a lifting mechanism (USSR Author's certificate No. 351968, CL EV 13/00, 1970).
The disadvantage of this device is its low reliability in the presence of the flow of sediments drawn, when the gaps between the rods of the lattice can get carried sediment and floating debris, which may cause jamming of the lattice and a decrease in throughput.
Also known outlet of the channel with steep slopes containing transit tray, bottom distributor and its ceiling is made in the form of a shield and grille, hinged at one edge to the bottom of transit tray and freely resting the other on the free edge of the shield (USSR Author's certificate No. 881191, CL EV 13/00, 1981).
However, the known device is also not reliable enough, because the grid and the shield are fixed ledge at the bottom of the tray, contributing to the rapid clogging of the grid, any change in the flow rate of the discharge, creating for him zone sbeinati flow and the inevitable splashing over the side of the tray. Lattice, in addition, heavily hammered floating debris during low urovnevoi over it. Cleaning of these structures represents a major difficulty in the turbulent flow that does not provide stabilization pick in the irrigation system water flow. Cleaning mesh requires the creation of a relatively expensive engineering structures to ensure the conditions for its functioning (brush, hydraulic flushing and so on).
Know the intake device of the irrigation system, including the transit of the canal, the drainage gate at the entrance and the recipient camera with skimming wall and litter retaining bars (USSR Author's certificate No. 1372012, CL EV 13/00, 1986).
A disadvantage of the known device is that it applies to channels with quiet mode currents flow and requires an additional camera, the bottom of which can be partially filled with sediment, and also hit the top into the cavity skimming walls of leaves from trees and other dirt and slush on the outer surface of the lattice with longitudinal rods. Insufficient effectiveness of the lattice does not allow for reliable continuous operation of the device during its operation. When the accumulation of large amounts of waste on the grate in the well comes less water, resulting in the clogging of the holes of the floating debris. In addition, you need to open frequently washing the hole in the building with a large discharge of water in tra the attributes of the channel, what is undesirable in the irrigation period for irrigation equipment. Thus, the wash-out garbage in manual mode, i.e. it is necessary to forcibly discharge a large amount of water for leaching of sediment and debris. Then re-fill the water chamber is leading to water shortages for consumers, respectively, irrigation technique does not work. The conclusion is that this technology is not completely clears the grid, thereby reducing the effectiveness of treatment. Note that when the water intake on systems with a closed pipeline network needs to maintain a steady flow of water. For example, for irrigation from groundwater microhydrated or sprinkling machines, when the channel gets roiled stream containing sediment, different kind of garbage, it seems appropriate short-acting stationary device, which greatly simplifies operation, increases the efficiency of the structure. In addition, there should be auto washed away by the flow of sediment downstream constantly.
The purpose of the invention is the increased efficiency in the work by cleaning the grates from the accumulation of driftwood and sediment and protect them from the bottom opening of the pipeline.
This objective is achieved in that the device for cleaning water outlet from pollution, including the transit of the canal, the drainage gate is the entrance and the recipient camera with skimming wall and trash bars, skimming the wall is made from the top of a hollow tube with vent holes and perforated tubes placed on motorsystem device, fixed side outlet mouserotate device in the form of a grid connected to a source of compressed air supplied by briefly compressor, coupled with a time relay in the duct into the hollow tube, and the grille is installed on the outlet lines in the input part of the flat shutter, with a vertical wall with a drive through which transit the canal is blocked, positioned above the horizontal dividing plate with V-neck, one end of which is bent at an acute angle to its plane, freely available on the plate and directed toward the inlet channel. In addition, the tapered protrusion is placed at the bottom of the inlet channel in its lower part and turned to the camera and to transit the canal, the other end of the vertical wall freely communicates with the tab.
This embodiment of the device for cleaning water outlet from contamination allows, in comparison with the prototype, to automate the process of securing an outlet with a lattice from a blockage of the fins and sediments, i.e. clogging of the holes of the lattice various fin and debris removal from the terminals reset, sohranyaemostyu the ability of the holes. The destruction of the apparent blockage in the team relay time is short turning on the compressor and the flow of compressed air across the section of the lattice. Reduces the flushing of sediment and various debris. In addition, the redistribution of the velocity of the flow structure over the water intake chamber, i.e. the horizontal separator plate with a vertical wall, allows you to enter the flow in the parallel-flow form, which prevents the formation in the zone of allocation of sbeinati stream, fountains and splashing over the side of the building. Additionally it should be noted that this embodiment of the design of water treatment sediment and floating debris from the lattice leads to the possibility of flushing the turbulent flow is more efficient in transit the canal, without creating hydraulic screen. The air supply is made by flexible hoses (flexible communication line) from the hollow pipe to the perforated tubes mounted on the grille side of the drainage, which allows the throughput of the holes to keep. Floating debris buildup (fouling) does not occur. In addition, increased operational reliability and is due to the absence of the grating elements of the hydraulic actuator and other moving parts on it, complicating the device. This in turn provides stabilization intake is about in the irrigation system water flow, reduces at least 5-10% loss of water to discharge and increases the productivity of the staff of the irrigation system.
It should be noted that the design of the device, according to the author, was not previously known and meets the criterion of "significant differences".

A device for washing water outlet from contamination includes inlet 1 and transit 2 channels, articulated by the camera 3. At the end of the inlet channel 1 is placed a conical protrusion 4 and is located in the same plane with the bottom of the chamber 3. To the wall of the chamber 3 adjacent the discharge pipe 5 with the flat shutter 6 in the input part, and at the entrance of which is rigidly mounted skimming the wall 7 from the top with a horizontal pipe 8, trash grating 9 and the tube 8 is made hollow, having in the lower part of the air outlet 10. Horizontal pipe 7 is installed on the axial bearings 11 with the possibility of its turning and lifting, with holes 10 is pneumatically communicated through a flexible hose 12 (flexible lines) with perforated tubes 13 arranged on the grid 8 from the side of the outlet pipe 5 with the flat shutter 6, and the floor is the efficiency of the pipe 8 is connected with a compressor (To) 14 compressed air, supplied by the duct 15 in a horizontal pipe 8. The compressor (To) 14 is connected to the relay (R) 16 time.
Protection of the outlet from blockage by sediment and floating debris (grass, leaves, etc. is the following: the worker process mode osvetleni water in the irrigation system through the bars 9 with perforated tubes 13, characterized periodically with compressed air, as if the outlet is not able to perform its function as sediment in large quantities of small size can get in the closed irrigation system and large size fractions of sediments drawn can cause damage to the lattice and jamming between the rods.
The horizontal plate 18 with the divider 19 is installed above the bottom of the inlet channel 1 and above the tab 4 and is rigidly connected with the walls of the channel 1. Since a given flow of water through the discharge pipe can come only below the horizontal plate 17 at a given pressure regime of the flow in the chamber 3, to ensure operation of the pipeline 5 full cross-section through the bars 9 at the water intake of the inlet channel 1, as well as in moments of lack of water intake and thereby eliminate the retaining mode in the inlet channel 1, there is no blockage by sediment and floating debris as the camera 3 with the bars 9 and the inlet channel 1, if e is ω compressor (K) 14 off from work. Set the vertical wall 19 of chamber shape can be rotated in the direction of transit of the channel 2 with the lift 20 and the upper end 21, freely moving on the horizontal plane of the plate 17 and which is bent at an acute angle to its plane in the direction of the inlet channel 1 and streamlining the free end 21 of the wall 19. The lower end 22 of the plate 17 is freely interacts with the end face 4 side of the transit channel 2.

Water together with any fin, debris, drawn and suspended sediment flows through the inlet channel 1. On the supply channel is the first division of the flow of the horizontal plate 17 with the divider 18. Part of the flow is sent to the transit channel 2, i.e. above the horizontal plate 17 in parallel to the jet shape that prevents in the area of water allocation to the education of sbeinati stream, fountains and splashing over the side of the building. At the same time another part of the flow drawn and suspended sediments (possibly in the middle of the stream and waste) goes under the plate 17 into the chamber 3, from which is regulated by one part of the flow coming through the grate in the discharge pipe 5, and the other sediment enters the transit channel 2.
To bring the design into a working floor is laid on the inner cavity of the pipe 8 from a source of compressed pressurized air, which is supplied through a flexible hose 12 (flexible lines) in the perforated tube 13 fixed to the plane of the grating 9 side outlet pipe 5 with the flat shutter 6. Thanks harvested and suspended sediment, and litter intensively moved to transit the canal. The required air flow rate for the cleaning of the grating 9, and consequently, the sediment and debris is not deposited on the rods of the lattice, and the throughput is stabilized in a discharge pipe 5.
This embodiment of the device provides the abstraction of water regardless of the horizons of the channel and its contamination (the presence of sediment and floating debris, trash constantly breaks away from the grille and continuously moving stream along the grid and beyond its limits with high speed water.
The economic efficiency of the device for cleaning water outlet from blockage by sediment and debris is to improve the effectiveness of its work on channels with steeper slopes by providing an automatically adjustable modes of operation of the compressor and thereby prevent clogging of the grid 9.

SUBSTANCE: method involves cutting slits on plot to be desalinized; feeding rinse water onto strips between slits; removing salt from slit surfaces and spilling soil therein, with slits being cut to depth exceeding depth of season soil wetting with precipitation; providing cavities on strips between slits; closing cavities with shields of hydrophobic water-impermeable material, said shields being equipped with perforations extending along their central axes and float members; fastening shield edges in upper part of slits; providing soil desalinization facilitated by precipitation. Upon precipitation, rain water flows over walls of cavities to infiltrate through perforations and fill cavities bottom part, with the result that salt is washed into depth of soil to be desalinized. Moisture will be preferably moved by capillary force and due to evaporation of moisture from slit wall surfaces toward slit walls, accompanied by accumulation thereon of salts. Washing process may be accomplished during one or several seasons depending upon precipitation intensity and salt concentration. After completing of desalinization processes, shields are removed, salts are buried by spilling soil into slits, and soil on desalinized plot is mellowed to depth of season soil wetting. Burying of salts at the level below depth of season soil wetting and destruction of capillaries by deep mellowing of desalinized soil layer protect it from secondary salinization.
EFFECT: increased fertility of agricultural areas on unirrigated agricultural lands in the absence of potable water sources without the necessity of constructing expensive water feeding systems.
