The invention relates to irrigation systems and applies proportional allocation at the gutter channels.

Known water divider with a vertical wall, the hinge is installed parallel to the axis of the partial stream and mounted for movement by the actuator (USSR Author's certificate No. 143725, CL E02B 13/00, 1961).

The disadvantage of this water divider is a complex construction of the separation wall, water divider does not take into account the small cross-section and shape of the flume channel. Part of the elements connected by the hinges, causing water corrosion of the past and create a big effort to move the wall at an angle in the places of discharge channels. On the bending vibration appears parts of variable pressures on water flow, i.e. shock loads.

Known also water divider for the UV channels, including inlet and outlet channels, and the bottom of the outlet channel is connected with the bottom of the inlet channel in the form of a drop, in the middle part of the height of it is elastic partition wall, the upper edge of which is fastened to the flow divider, and a vertical wall (USSR Author's certificate No. 1008348, CL E02B 13/00, 1980).

A disadvantage of the known device is that the flowing stream of water in the inlet parabolic tray has a width l of the TKA different running costs, accordingly, the speed of the vertical will be different, that violates a given proportionality division of the flow, i.e. a given coefficient of proportionality, in cases, if there was an opportunity to carry out drive control in the horizontal plane to the set point of the desired width of the chamber and the outlet channels. Therefore, in the known construction is provided for guiding the horizontal plate. Another disadvantage is the need to create greater efforts to move the flow divider with a vertical transverse plate rigidly connected bottom hem with elastic partition wall, the bottom end rigidly connected to the bottom of the well. When interacting with the flow transverse plate also having a large hydrodynamic loads on vertical movement, which allows the division of the flow of water is limited only vertically in front of the intake channel. In addition, the closure of one of the side canals gate leads to sbeinati flow before the flow divider, and water begins to flow over the horizontal guide plate, and this further increases the weight and force is required to move volumelicensing body. The design of the water divider is difficult during installation.

The purpose of the invention is improving the efficiency by reducing the gain is second to move and control the speed of the flow pattern in the area of water allocation.

This goal is achieved by the fact that in a proportional water divider for the UV channels, including inlet and outlet channels, and the bottom of the outlet channel is connected with the bottom of the inlet channel in the form of a drop, in the middle part of the height of it is elastic partition wall, the upper edge of which is fixed to the flow divider, and a vertical wall, the elastic partition wall is provided on the outer contour of the hard shoulder as a mobile holder, which upper end is connected to the flow divider in the form of a vertical plate, with the possibility of interacting with it along the axis of the discharge channel with the inlet channel is connected with the distribution of the camera, extended plan rectangular cross-section and the other end installed on top of the bead outlet channel in the form of a cantilever portion with a gap in the junction relative to the bottom of the tailrace and overlapping the upper part of the bore of said channel, and on the opposite side wall of the discharge channel is fixed a vertical wall of the chamber, with the bottom of the distribution chamber is provided with a plate-threshold front of the flow divider, addressed to flow with reverse bias, the flow divider is made of a compound from a vertical plate with a Central hole, is installed on the horizontal axis, moving what Baumol, with the possibility of horizontal translational movement along the axis of the discharge channel within the operating position across the width of the cantilever part of the camera, and the ratio of length to width of the plate-threshold is not less than 1 angle 10...15° relative to the bottom of the distribution chamber.

This embodiment allows the use of balanced water divider on the flume irrigation canals parabolic shape, i.e. takes into account the small cross-section and shape of the flume channel, allows to reduce the load perceived by the mobile part of the tool and, consequently, to reduce the dimensions of the water divider. In addition, take into account the hydraulic parameters of flow of the flume channel to obtain the specified structure of the velocity distribution at the height of the filling. Ensures even distribution of water flow across the width of the plate-threshold, does not violate a given proportionality dividing flow vertical plate with a rigid belt in the form of a mobile holder mounted on the cross-sectional shape of the bed of the discharge channel with the horizontal translational movement.

The stream of water flowing through the inlet channel means in the extended part of it with a camera equipped with a plate-threshold, with a specified movement on the stove-the threshold angle of 10...15° to the bottom of the distribution chamber, the extension of the military in the plan, with a length to width ratio of the plate-threshold is not less than 1. The angle of the plate-threshold has the opposite slope before the flow divider and does not violate the structure of the velocity distribution.

This means that the proportional water divider performs a proportional water distribution on parabolic troughs with n taps of the mentioned channels. The design of the water divider is quite simple.

The authors are not aware of any device that contains a similar relationship in solving the problem of proportional division in the gutter channels parabolic form, therefore, in their opinion, the proposed solution has the criterion of "Significant differences".

Figure 1 shows the water divider, in a perspective view; figure 2 is a top view; figure 3 is a section a-a in figure 2; figure 4 is a cross-section B-B in figure 2; figure 5 is a plot of the velocity distribution in the area of water allocation before and after the device camera extension with plate-threshold.

Proportional water divider for the UV channels consists of the inlet channel 1 and the discharge channel 2, which has an elastic partition wall 3, is provided on the outer contour of the hard shoulder as a mobile holder 4 attached from above to the flow divider in the form of a vertical plate 5. The vertical plate 5 with the movable holder 4 is moved along the axis of the discharge channel 2, and a movable ferrule 4 vol is Lana on section referred to channel 2. The inlet channel is connected with the distributing chamber 6, extended in terms of rectangular cross-section and set the other end on top of the bead outlet channel 2 in a cantilever portion with a gap in the junction relative to the bottom of the discharge channel 2 and overlapping the upper part of the bore of said channel 2. On the opposite wall side of the discharge channel 2 is fixed to the vertical wall 7 of the distribution chamber 6, extended in plan and provided with a plate-threshold 9 before the flow divider, made in the form of a vertical plate 5, facing the stream with a reverse bias. The flow divider is made of a composite of the vertical plate 5 with a Central hole, with a movable holder 4, the horizontal axis 10 in the form of a rod, which is connected to the actuator 11, made in the form of a worm shaft, a sleeve 12 with thread, with bearings 13. The sleeve 12 is moved together with the vertical plate 5 and the movable holder 4, the actuator 10 horizontally-and-forth along the axis of the discharge channel 2 within the operating position across the width of the cantilever portion of the chamber 6, while supporting the bearings 13 are placed on the side walls of the cantilever part of the chamber 6, and the sleeve 12 is fixed in the hole of the vertical plate 5. The ratio of length to width of the plate-threshold 9 is not less than 1, and the angle at which the womb is 10...15° relative to the bottom 8 of the distribution chamber 6. The transition portion of the chamber 6 with plate-threshold 9 has a length L and width of Owner.

Proportional water divider operates as follows.

The principle of the water divider based on the use of hydraulic properties of the stream. The task of the program allocation, i.e. a given coefficient of proportionality K, carried by the actuator 11 management and reduced to the desired width of the cantilever part of the distribution chamber 6 above the outlet lotkov, channel 2 and in front of the oven-threshold 9 according to the formula K=b1/b2(where b1and b2accordingly, the width of the cantilever spans of the camera 6). This can be represented in the form

Q1=mpl.b1√2gho3/2;

Q2=mpl.b2√2gho3/2,

i.e. when K=Q1/Q2=b1/b2=const.

If you want to change the ratio of the cost of the required value of the vertical plate 5 with the movable holder 4, equipped with a waterproof elastic partition (maybe progressiva fabric) and executed on the cross-sectional shape of the discharge channel 2 within the operating position across the width of the cantilever portion of the chamber 6, is moved horizontally and forth along the axis of channel 2 drive 11 in the guide support bearings 13, which allows the proportional allocation on soo is ugenia with n taps.

To eliminate sharp expansion in the transition area of the inlet channel 1, is paired with a distribution chamber 6 in terms of rectangular cross-section, and the violation of hydraulic structures in the flow stream width has a stove-threshold 9 facing the flow with a backward slope in front of the vertical plate 5 tract discharge channel 2, and the ratio of the length to the width of the plate-threshold 9 is not less than 1 angle 10...15° relative to the bottom 8 of the chamber 6, which provides a defined structure of the velocity distribution at the height of the filling. This in turn provides a uniform distribution of flow across the width of the plate-threshold 9 without disturbing the desired proportionality dividing flow vertical plate 5 with the movable holder 4 along the axis of the discharge channel 2.

Stove-threshold 9 is arranged such length L that he had a reverse bias, to meet the flow of water, and would almost uniform mode distribution chamber 6 before the vertical plate 5 fixed on the horizontal axis 10 with the possibility of horizontal translational movement simultaneously with the movable holder 4 along the axis of the discharge channel 2.

Figure 5 shows plots of the velocity distribution in the area of water allocation without plate-threshold and with the proposed device plate-threshold 9 width of modelinia.

The implementation of the giving of the distribution chamber placed in a stove-threshold, set flow reverse bias relative to the bottom of the camera, you can influence the hydraulic structure of the flume channel parabolic shape, providing a reliable work of the working bodies in the water, and reduces the load on the cantilever part, towering above the bottom of the tailrace, protects bearings and worm shaft with a movable vertical plate and a movable clip from getting jammed and provides full speed within the operating position across the width of the cantilever part of the camera.

Thus, in the console part of the chamber 6 is bounded by side walls and a vertical wall 7, is fixed on the Board of the discharge channel 2 is obtained proportional allocation, which reduces the load perceived by the mobile part of the working bodies and, consequently, to reduce the dimensions of the water divider, to simplify the structure as compared with the prototype on the basis of the interrelation and interdependence of the major elements of the water distribution facilities, which increases the efficiency of water allocation.

FIELD: agriculture, in particular, desalinization of saline soil of agricultural lands.

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.
