The invention relates to irrigation systems and can be used to regulate the water level in the paddy fields in discrete mode, i.e. in alternating cycles of filling and water level regulation of the magnitude of the drawdown.

Known level control in pools of hydraulic structures (ed. St. SU # 1236435 A1)containing a shutter mounted on the water outlet hole on the horizontal axis of rotation, the control chamber of the elastic capacity, placed in the cavity bounded by the shutter housing provided with dams channels, one of which has a valve associated with a level sensor. The disadvantage of this device is the presence of concrete foundations with a system of channels exposed to contamination, cracking and destruction, as well as the inability discrete level control in paddy fields.

Also known invention (patent RU 2228537 C2, G05D 9/00, 01G 25/16, 2004 by the authors is used as a prototype), automated cheque outlet, containing a shutter consisting of three sites, forming a closed air space, mounted on the water outlet hole on the horizontal axis of rotation, the control chamber of the elastic membrane provided with dams channels, one of which has a valve associated with a level sensor, vypolnennym the form of a telescopic system with longitudinal grooves on the outer part and stop of the control range on the inside.

A disadvantage of the known device is that it has a limited adjustment range of the magnitude of the drawdown of the water level in the paddy fields (within the size of the external part of the telescopic system) and a telescopic system is complex from a design standpoint and from the standpoint of change of the control range during operation during flooding.

As a disadvantage of the design is the lack of a device for locking in the closed position of the valve control chamber. Hold the valve in the closed position occurs due to the hydrostatic pressure on the soles on the part of the headrace channel. However, at low pressures, as experience shows, the pressure in the control chamber slightly, and the valve is closed, once opened at the beginning of the cycle of lowering the telescopic system. When this occurs, the filling of the downstream and the set of discrete regime the magnitude of the drawdown level is not reached.

The technical result is the extension of the range of regulation and stabilization device operating at different pressures.

The technical result is achieved by the fact that automated cheque outlet for discrete level control downstream, containing a shutter mounted on the water outlet hole on the horizontal axis of rotation, the control to the measure with elastic shell, communicated with pools, a valve associated with the level sensor, the limiter control range, according to the invention is equipped with a rod for fixing a range of discrete regulation in a wide range, having a movable float level sensor and the control chamber provided with outlet pipe which is a magnet for fixing the valve, thus limiting the control range is made in the form of clamps, one of which is located in the upper part of the stem above the movable float level sensor, and the other is located above the outlet pipe of the flow chamber.

The novelty of the claimed proposal is that in the design of automated cheque outlet for discrete level control the downstream of a new set of structural characteristics, including a rod with a movable float level sensor and a permanent magnet, is provided by a wide range and reliability discrete regulation under different pressures on the structure.

According to the patent and scientific literature is not found similar technical proposal that allows to judge about the level of invention proposals.

The invention is illustrated by drawings, where figure 1 shows the design of an automated chekova the water outlet for the discrete level control downstream, the figure 2 shows the status of the automated checking of the discharge and its structural elements in the mode of drawdown of the water level in the downstream, figure 3 shows the status of the automated checking of the discharge mode of filling the bottom of the pool.

Automated cheque outlet for discrete level control downstream consists of inlet pipe 1, receipt of the tip 2, the level regulator 3 with the bolt 4 with the upper platform 5 and the axis of rotation of the shutter 6. The controller casing layer 3 is a metal pipe, the open end of which is fixed in the inlet pipe 1 spacer screws 7. The second end of the pipe body level regulator 3 has an angular cut, and the degree of opening is determined by the magnitude of the elevation of the shutter 4 by turning it about the axis of rotation 6. In the upper part of the body of the regulator 3 is fixed cover 8 of the control chamber 9. Inside the control chamber 9 is fixed elastic container 10. The elastic container 10 is a rubber membrane with a hole in the top through which it enters the lower edge of the outlet pipe 11 of the supply tube 12. The inlet 13 of the supply tube 12 is fixed in the upper part of the body of the level regulator 3 through the inlet pipe 1 is communicated with the upper downstream of the culvert. The supply tube 12 anastasiei cover 14 to clean from clogging. The upper edge of the outlet pipe 11 has a constriction in the form of a ledge 15 and the guide part 16 with holes 17. On the guide part 16 of the outlet pipe 11 is placed a permanent magnet 18. The magnet 18 is made in the form of a disk with a through hole and is located on the ledge 15 of the guide 16. Through the guide 16 into the output nozzle 11 includes a rod 19. The rod 19 has a cylindrical shape, is made with a diameter of 7-10 mm of plastics material or of namagnichivanii metals (copper, aluminium etc). The length of the rod 19 is determined by the amount of penetration of the inlet pipe 1 at the time of construction of the rice irrigation system and can vary within a wide range (0.5-1.5 m) and allows a wide range of discrete regulation. The lower end of the rod 19 has a valve 20. The valve 20 is made of steel and may be attached to the inner part of the ledge 15 due to the attraction from the magnet 18. The rod 19 has the latch from dropping 21, the position lock minimum level downstream (UNBmin) 22 located above the guide 16, the position lock maximum level downstream (UNBmax) 23 located in the upper part of the rod 19, and a movable float level sensor 24. The tabs are cylindrical metal rods with a length of about 50 mm and a diameter of 2.5-3 mm, mounted on the rod 19 in the holes, carried out is the entire length of the rod 19 with step 7 mm Movable float level sensor 24 (in the form of a cylindrical sealed metal boxes) has a through hole 25, allowing it to move along the rod 19.

Automated cheque outlet for discrete level control downstream works as follows.

The level regulator 3, mounted on the inlet pipe 1 carries out discrete metered water flow in the lower reach with a given range of drawdown level Δ, equal to the difference between the specified maximum marks (UNBmax) and minimum (UNBmin) levels downstream (figure 1). During the filling of the downstream water to the maximum mark UNBmaxmovable float level sensor 24, following the water level affects the latch 23 maximum level downstream and raises the rod 19 with the valve 20. The valve 20 rises inside the top edge of the outlet pipe 11 and (when the water level downstream of the maximum value) is fixed in the closed position on the inner surface of the ledge 15 due to the impact of the magnet 18. The water flowing in a nutrient tube 12, loses the possibility of expiration in the lower reach and enters the elastic container 10 under the action of pressure, equal to the difference of levels in the dams Zmin. The elastic container 10 is filled, the pressure on the lid 8 of the control chamber 9 is at the top of the pad 5 of the bolt 4. The area of the upper platform 5 shutter 4 is calculated in such a way that it exceeded the size of the shutter 4, adjacent to the corner edge of the pipe body level regulator 3. As in this case, the pressure on the bolt from the top side of the platform 5 is greater than the pressure on the bottom face of the stopper 4 on the corner slice, then the shutter falls, turning around the axis of rotation 6 stops the water flow in the lower reach. Further, the water level in the downstream decreases due to the consumption of water for infiltration, evaporation, flow, etc. of the Rod 19 is held by the magnet 18 and the valve 20 remains in its upper position, and a movable float level sensor 24 is lowered (figure 2). When the water level reaches the minimum value (UNBmin) movable float level sensor 24 presses downwards on the clamper 22 downstream, thereby lifts the valve 20 from the plane of the ledge 15. Breakaway valve 20 leads to the lowering of the rod 19, which is due to bearing retainer 21 and the guide 16 is lowered so that the valve 20 has not established a resistance to the movement of water in the outlet port 11 of the nutrient tube 12. At the bottom position of the valve 20 is a decrease in the pressure in the control chamber 9, the water from the elastic container 10 is displaced in the lower reach through the holes 17. The flow of water through the supply tube 12 due to the fact that the square hole at back is s 17 more square holes in the lower part of the outlet pipe 11 is directed into the lower reach. The shutter 4 is opened and begins filling the downstream water. Movable float level sensor 24 when the water level in the downstream is moved vertically upward along the rod 19 (figure 3) and at the approach level downstream to the level of UNBmaxraises the rod 19 due to the impact on the latch maximum level downstream 23. In the extreme upper position of the rod 19 (UNBmaxvalve 20 is again fixed by the magnet 18 in the closed position on the ledge 15, the shutter 4 is closed and starts the cycle of water level downstream to the level of UNBmin.

Automated cheque outlet for discrete level control downstream, containing a shutter mounted on the water outlet hole on the horizontal axis of rotation, a control chamber with a flexible membrane provided with dams, the valve associated with the level sensor, the limiter control range, characterized in that it is equipped with a rod for fixing a range of discrete regulation in a wide range, having a movable float level sensor and the control chamber is equipped with outlet pipe, which is a magnet for fixing the valve, thus limiting the control range is made in the form of clamps, one of which is located in the upper part of the stem above the movable float mitchiko the level while others are located above the outlet pipe of the flow chamber.

FIELD: irrigation systems used for automatic watering of plants on restricted area plots.

SUBSTANCE: apparatus has accumulating vessel with bottom opening closed with valve, auxiliary vessel, two float valves, one of float valves being adapted for supplying of water into accumulating vessel and other float valve being adapted for cutting-off water supply. Valve floats are arranged in auxiliary vessel disposed below accumulating vessel bottom and connected by means of flexible pipes with hermetically sealed vessels provided with porous bottoms deepened into soil. When water is sucked through porous bottoms into soil, water level in auxiliary vessel is lowered and float valves are opened, with water being delivered into accumulating vessel through one of float valves. When predetermined water level is reached, valve for discharge opening is opened, water is supplied into low-pressure irrigation system and is further delivered through second float valve into auxiliary vessel. As a result, water level in auxiliary vessel is increased to cut-off water supply into accumulating vessel.

EFFECT: increased efficiency and simplified construction.
