Abstract

FIELD: agriculture.

SUBSTANCE: mouth of the drain collector comprises a water intake chamber 6 formed as a washing gallery and a chamber 12 separated by a partition wall 4 in the well 5. A water outlet 3 is located between the water intake chamber 6 and the second chamber 12 via the partition wall 4. At that, the water outlet 3 comprises a plug valve 11, the rod 13 of which is connected through a pivot system 14 with a float sensor 17. The plug valve 11 is oriented coaxially with the drain hole 10 of the outlet 3 with the fixed lower stem 18. The stem 18 is connected through a hinge 19 and a lever 20 with a valve 9 overlapping the outlet 8 opening. The washing gallery 6 is adjacent to the input of the outlet 8. The second chamber 12 is connected to a discharge manifold 23. Inclusion of an outlet 6 with a valve 9 in the device at the end of the bottom 7 of the chamber 6 allows to provide a link to the water outlet 3 with the plug valve 11, automatic control of water level in the well 5, as well as a possibility to protect against bottom sediments and floating debris falling into the water outlet 3. Reliability in transient modes depending on water filling and bottom sediment accumulation in the chamber 6, coming from the collector 2, will be achieved by reduced material consumption and simplified design, consisting of two chambers, one valve, and reduced number of stems that affect plug valve operation in the water outlet.

EFFECT: simplified design, reduced material consumption and improved protection of mouth operation against sediment and floating debris getting into the water outlet.

Description

The invention relates to the field of land reclamation and can be used for automatic regulation of groundwater, mainly for drainage systems.

A known regulator of groundwater level, including a locking element mounted on the inlet head of the drainage drain, a float with a rod, a drainage well and a pipe, the locking element is equipped with a lever pivotally attached at one end to the rod (Patent RU No. 2530527, ЕВВ 11/00, G05D 9 / 02 dated 10.25.2014).

The disadvantage of this device is the presence of the float chamber, its high-altitude location in the well and three rods of large length in it, which makes the operation of the device quite cumbersome when slowly filling the water and thereby filling the float chamber and, as a result, a large material consumption. In addition, low reliability is a consequence of the arrival of fin and debris in the float chamber and their retention by a valve in the tube, i.e. since the operation of the chamber is only related to clean water and cannot affect the intensive removal of bottom and suspended sediments.

The closest in design to the proposed one is the mouth of the drainage collector, including a shut-off body with a float actuator and a rod mounted on the head of the drain located in the drainage well, it is equipped with a hydraulic relay in the form of two sealed chambers with two inlets and two outlets, and a water outlet is made at the bottom of the first chamber, which is blocked by a valve that is connected to the float by an articulated lever actuator located in a water-filled container with a calibrated a single outlet having a limiter for displacing the float, and the second chamber contains an inlet nozzle equipped with a valve installed at its end, connected through the stem to the valve of the first chamber with the possibility of vertical movement relative to each other, and the second chamber is in communication with the drain through the check valve, and the valve with a drain pipe (Patent RU No. 2538811, ЕВВ 11/00 dated 12/23/2014).

The disadvantage of this device is cumbersome and, as a consequence, a large metal consumption. In addition, it is difficult constructively, including two inlet chambers, while the second (lower) chamber, like the float chamber, operates in difficult conditions with floating debris and suspended sediment particles, which does not allow for reliable long-term operation of the device during its operation. At the same time, it has little effect on the intensity of removal of bottom and bottom sediments.

The technical result from the use of the claimed invention is to simplify the design, increase work efficiency and reduce material consumption.

The technical result is achieved by the fact that for the mouth of the drainage manifold, which includes a shut-off body with a float actuator and a rod located in the drainage well, it will have a water outlet with a drain hole, inside of which there is a cork shutter oriented aligned with the cavity of the water outlet with a fixed lower rod and hinge its connection with the valve lever of the float actuator, while the water outlet is connected to the intake chamber, the intake chamber being made in the form of a washing r gallery, which is adjacent to the exhaust pipe, equipped with a valve pivotally connected through a lever with the lower stem of the cork shutter.

In addition, the outlet of the washing gallery is located below the outlet with a cork shutter.

The drawing shows a schematic diagram of a drainage collector.

The device contains placed drains 1, a collector 2, a water outlet 3 installed in the dividing wall 4 in the well 5. The collector 2 is connected to a water inlet chamber 6, made in the form of a washing gallery, the bottom 7 of which is adjacent to the outlet 8 equipped with a valve 9 The water outlet (cranked) pipe 3 with a drain hole 10 comprises a plug valve 11, while the outlet drain hole 10 of the pipe 3 is located in the second chamber 12 of the well 5. In addition, the plug valve 11 is fixed to the rod 13 by an articulated lever system 14, which is fixed by the middle part with a hinge 15 on the dividing wall 4, and the other end is connected to the rod 16 with the float 17. In this case, the cork shutter 11 is oriented coaxially with the outlet drain hole 10 of the pipe 3 with the fixed lower rod 18, the end of which is connected by a hinge 19 with a lever 20 of the valve 9. The inlet of the water outlet 3 is blocked by a grate 21 to eliminate the ingress of floating debris and sediment into the cavity of the pipe 3 with a cork shutter 11. The grate 21 is removable. The float 17 is provided with a latch 22, which allows the float 17 to be fixed at different predetermined levels. The bottom 7 of the washing gallery 6 is made inclined towards the outlet pipe 8 with a valve 9, in communication with the second chamber 12 of the well 5 with the outlet manifold 23.

The mouth of the drainage collector works as follows.

When water enters the collector 2 further into the water intake chamber 6 and with a small (small) level of filling, its float 17 is in the lower position and the outlet outlet 10 of the pipe 3 is open by a plug valve 11. In this case, the valve 9 is closed by means of a lever 20 with a rod 18. The discharged water from the collector 2, first of all, enters the water intake chamber 6, which is sedimentary and made in the form of a washing gallery, therefore, fin and sediments (drawn and suspended) accumulate in it, the characteristic size of which is present in the collector D 2.

When the water level in the chamber 6 is raised, the float 17 rises, acting on the articulated lever gear 14 and the stem 13, so that the cork shutter 11 overlaps the drain hole 10 of the pipe 3 and simultaneously through the lower rod 18, lever 20, valve 9 opens the outlet pipe 8 .

The flow rate of water flowing from the wash gallery 6 allows these sediments and fin to pass through the outlet pipe 8 into the second chamber 12 free of baffles than the size of the holes of the grill 21 of the water outlet 3, and therefore, excess water enters the second chamber 12 with a discharge collector 23. When raising (lowering) the water level in the chamber 6 to a fixed position defined by the float 14 (float sensor) of the level with the retainer 22, the level float 14, floating (or lowering), regulates both the flushing of the chamber 6 and the flow d of water passing through the outlet 3 or outlet (lower) nozzle 8. Thus, the bottom and suspended sediments fall to the bottom 7 of the chamber 6, their retention does not occur for a long time in this niche in the area of the washing lower nozzle 8 due to the increasing speed water flow along an inclined bottom 7.

The claimed invention is industrially feasible. Thus, conditions are created for washing the chamber 6, increasing to protect the water outlet 3 of all types of sediment in the upper and lower water layer coming from the collector 2, as well as the relative position of the water outlet (elbow) pipe and the outlet (lower) pipe 7 of different geometric sizes due to changes in water levels in the intake chamber 6.

In turn, this makes it possible to work in the automatic mode of the mouth of the drainage collector. The proposed device allows to simplify the design by eliminating one chamber, one valve and reduce the number of other elements, thereby reducing material consumption.

The elements of the device of the mouth of the drainage collector can be made lightweight to be able to control the level and efficiently operate the water level in the collector 2, which expands the scope and time of operation of the mouth as a whole.
