Description

The invention relates to land reclamation and can be used to automatically control the level of groundwater.

Known regulator of the water level in the drainage network, including a shut-off element mounted on the inlet head of the drainage pipe, a float and a rod, a drainage well and an outlet pipe (Copyright certificate SU No. 496349, class ЕВВ 11/00 dated 12/25/1975).

A disadvantage of the known regulator is the low efficiency of regulating the water regime of the soil, as well as the need for manual adjustment to switch to another mode and the delay property of the opening process of a locking member made of valves interconnected by rods, the lower valve being located inside the locking member and the upper one outside , in this regard, it is not sensitive enough to changes in the water level in the well, it requires a higher quality of manufacturing of the actuator, since due to of perpendicular valves having a common stem, the lower valve may fail to work when it is jammed in the housing due to corrosion or contamination, which leads to a sharp increase in resistance forces and the error in maintaining the water level in the well.

Also known is a groundwater level regulator containing a well, a shut-off element in the form of a valve, connected to the levers of the hinge mechanism, and a float (patent RU No. 2490394, CL ЕВВ 11/00, G05D 9/02 from 08/20/2013 )

The disadvantage of this device is the presence of nodes in the form of a counterweight container, a lever mechanism in the form of interconnected parts of the crossbar and a floating float in it, which makes the device cumbersome, requires precise mutual alignment of the lever mechanism and the angle between the two crossbars and, as a result, a large material consumption.

The closest to the intended purpose is the groundwater level regulator, which includes a shut-off element mounted on the inlet head of the drainage pipe, a float with a rod, a drainage well and a pipe, the shut-off element is equipped with a lever pivotally attached at one end to the rod (patent RU No. 2530527, class E02B 11/00, G05D 9/02 of 10.25.2014).

The disadvantage of this device is the presence of a 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 with slow filling of water and thereby filling the float chamber and, as a result, a large material consumption.

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

The technical result is achieved by the fact that in the groundwater level regulator including a shut-off element with a rod installed on the inlet head of the drainage pipe, a float with a rod, a drainage well and an outlet pipe, a shut-off element on the outlet pipe is equipped with a lever pivotally attached to the float rod, the rod the drainage locking element is provided with a U-shaped inverted cup with a spring located between the guides, one end of the spring being connected to the rod of the articulated lever drive, and the second to the locking rod a drainage organ with a retaining disk, made in the form of an inverted plate with the possibility of contacting the inlet nozzle seat, while a lever connected to a swinging axis mounted on a vertical strut is articulated at one end to the middle part of the rod connected to the spring in its upper part.

In addition, the well is additionally equipped with a hinged shutter pivotally connected to the wall of the well.

In addition, a spring-loaded locking element with a retaining disk, made in the form of an inverted plate, has the shape of a cone with curved side walls facing the flat seat of the nozzle.

In addition, the stem of the U-shaped inverted cup is made with an adjusting sleeve and with a travel stop.

The proposed level controller is aimed at eliminating these shortcomings by simplifying the design, the number of chambers and rods, as well as reducing material consumption.

The practical operability of the proposed device groundwater level controller is obvious and it fits into the design technology for drainage systems.

This design of the groundwater level regulator provides the ability to set the amount of free movement of the shut-off element with a shortened stem and with a spring attached at one end to the elongated stem of an adjustable U-shaped inverted cup with an adjusting sleeve (setting) on the stem, which in its upper part contacts the limiter fixed in the well. Installing a free tension spring inside the U-shaped inverted cup and adjusting the latter in height, mounted on an elongated rod, articulated in the middle with a two-arm lever, a float with a load on the swinging axis of the two-arm lever. At the same time, the locking member itself is made by a flat plate fixed to the retaining disk, which has the shape of a cone with side curved walls facing the nozzle seat with the possibility of overlapping the outlet of the nozzle seat, which is aligned with the open part of the inverted nozzle. Placing the open lower part of the glass with a spring allows you to ensure a stable position of the locking body when closing the saddle of the vertical pipe.

You should pay attention to the shape of the nozzle seat and the shape of the locking element with a retaining disk, made in the form of an inverted plate, this softens the blows on the edges of the guides, in which the U-shaped inverted glass with a rod with a spring moves.

Due to the streamlining of the side walls of the shutoff body, the water discharge into the cavity of the well without splashes is generally increased, and the resistance (loss) of the discharged water from the vertical pipe, which is absent in known devices, is reduced.

The drawing shows a schematic diagram of a groundwater level regulator.

The groundwater level controller includes a well 1 with an outlet pipe 2 of the collector, a hinged shutter 3 on the outlet pipe 2 with a lever 4 with a hinge 5, which is connected to the lever 6 through the two shoulders lever 6, the rod 7 and the rigid connections through the hinges 8, 9, 10, one end of which is connected by a hinge 10 with the middle part of the elongated rod 11 connected to the spring 12, and the float 13 and variable weight cargo 14 are fixed in the middle part of the rod 7 with the hinged shutter 3 of the exhaust pipe 2. The two-arm lever 6, which rotates on the axis 15, is fixed to stand 16, to The second one is fixed rigidly to the bottom 17 of the well 1. Position 18 denotes the stopper of the locking element 19 with the retaining disk 20 in the form of an inverted plate and mounted above the flat seat 21 at the end of the inlet pipe 22 connected to the inlet manifold 23. The spring 12 is placed in a U-shaped an inverted cup 24, which is located between the guides 25 with the partition 26. The shortened rod 27 of the locking member 19 of the drain with the retaining disk 20 is fixed to the lower end of the spring 12 and is placed in the guide sleeve 28 in the partition 26, while The stem 11 has an adjusting sleeve 29. Elements connected in the well 1 constitute a circuit diagram with an inverted cup 24 with a spring 12, a locking member 19 with a retaining disk 20, which is made in the form of an inverted plate, an inlet pipe 23 with a flat saddle 21, folding the shutter 3 of the exhaust pipe 2, with the sensing element, the float 13 and the articulated lever actuator.

The regulator is installed in the drainage well 1 and adjusted to a predetermined water level, for which the length of the rod 11 and the glass 24 are adjusted by the adjusting sleeve 29, the glass is held by a spring 12 connected to the shortened rod 27. A partition 26 s serves as a guide for the shortened rod 27 guide sleeve 28.

The proposed regulator operates as follows.

In the open position, the drain shutoff member 19 with the retaining disk 20 moves away from the seat 21 of the inlet pipe 22, respectively, through the spring 12, the inverted cup 24 moves up with the rod 11, and through the two-arm lever 6, the rod 7 with the float 13 with the load 14, a hinged shutter 3 closes the exhaust pipe 2 of the manifold. Water enters the well 1 and rises to the level when the lifting force of the float 13 becomes equal to and greater than the pressure of the water column on the hinged shutter 3 and the weight of the float 13 with the load 14. The buoyancy force of the water acting on the float 13 connected to the lever 6, rod 11 , with a cup 24 and a spring 12, opens the hinged shutter 3, discharges water through the outlet pipe 2 of the collector, and together with them the locking element 19 of the drain with the retaining disk 20 gradually falls, and close the inlet of the pipe 22 with the inlet manifold 23. When lowering the Nogo drains body 19 with retaining plate 20 and a rod 27 with a shortened due to the compression spring 12 presses the valve plug 19 drains to the disk 20 to the flat seat 21, nozzle 22, which are closed and are ready for the next cycle of operation.

The lifting height of the locking element 19 with the disk 20 is limited by the height of the rod 11 in the presence of a travel stop 18, at which the water stops draining from the well 1. As the water is filled in the well 1 to the float 13 in the raised state, the hinged shutter 3 gradually rises upward. with lever 4.

In the future, the process is repeated. The repetition period depends on the speed of filling the well 1 with water.

Thus, the principle of operation of the groundwater level regulator is as follows. When the water level in the well increases, the float begins to rise. The float with a rod is connected with a hinged shutter that opens the outlet pipe, and the shut-off element of the drain with the disk closes the inlet pipe through which the level of ground water is regulated until the drainage of water from the drainage well decreases accordingly.

The capacity of the described drainage well in each case is taken depending on the operating conditions, the adopted scheme for regulating the water supply and the length of the collector.

Thus, the water horizon in the well with a float hinged-lever control mechanism is regulated by the release of water flow from the drainage well in automatic mode.

The proposed groundwater level regulator allows to simplify the design and reduce material consumption in general.
