Abstract

The invention relates to land reclamation and can be used to automatically control the level of groundwater. The goal is to expand the range and improve the accuracy of groundwater level regulation. The regulator contains a well 1 with an outlet nozzle 2 communicated with two drains 4, 22, one of which 22 is hydraulically connected to the chamber 11 of a level 10 sensor connected to a balance bar 9 interacting with an elastic sheath 7 hydraulically communicated with a bellows 5. When when the groundwater level rises, the chamber 11 is filled with water, the hydrostatic pressure in the bellows 5 decreases, the water supply drain opens - the groundwater is discharged through the outlet nozzle 2. 1C. f-ly, 1 ill.

Description

The invention relates to the field of amelioration and can be used on closed drainage and drainage and humidification systems for automatic regulation of the groundwater level.

The purpose of the invention is to expand the range and improve the accuracy of regulating the level of groundwater,

The drawing shows the groundwater level controller, a general view.

The groundwater level regulator includes a well 1 with an outlet nozzle 2, a housing 3 with an inlet opening fixed to the water supply drain 4, inside which there is a shut-off element - bellows 5, one end of which is closed and the other is connected to pipe 6 with a closed an elastic sheath 7 located in the tank 8, the balance bar 9, the level sensor 10 in the form of a chamber 11 with a drain hole 12 for emptying it, blocks 13 and 14, a flexible cable 15 connecting the balance bar 9 to the chamber 11 by means of suspensions 16 and 17 , the adjusting screw 18 with the block 19 and rise 20, a flexible pipe 21 connecting the chamber 11 with the drain; Drain 22 is connected to the flexible pipe 21 by means of a pipe 23. A bellows 5 is connected by a pipe 24 with a funnel 25 and a valve 26 for filling the internal cavity of the closure member of the pipe 6 and the shell 7.

The groundwater level regulator works as follows.

Preliminarily, the inner shell 7 installed in the tank 3, the pipe 6 and the bellows 5 are filled with liquid (water) through a pipe 24 terminated in a funnel 25, and then the valve 26 is closed. The balance bar 9 is installed in the tank 8 above the shell 7, the chamber 11 is installed to the calculated groundwater level by means of an adjusting screw 13 and block 19 by changing the length of the cable 15 between block 14 and the suspension 16.

In the initial period, the inflow of groundwater into chamber 11 is less than the outflow from it through drain hole 12. As the level of groundwater rises, the influx of water into chamber 11 increases and exceeds the outflow of water from it, as a result of which the water level in chamber 11 rises. The weight of the camera is 11.

due to the weight of the water, increasing, exceeds the weight of the weight of the balance weight 9. As a result, the load rises and rests against the stopper 10, the force of hydrostatic pressure of water on the bellows 5 from the closed shell 7 decreases relative to the force of hydrostatic pressure of the drain 4. The bellows 5, Moving along the housing 3, releases the outlet section of the drain 4 for discharging groundwater, the inflow of groundwater in the chamber 11 through the pipe 23 and the flexible pipe 21 decreases. As a consequence, the chamber 11 occupies a position in which an equilibrium of forces is established, i.e. active hydrostatic pressure, and from the side of the closed shell 7 under the weight of the load, and from the side of the drain 4 on the bellows.

When the groundwater level drops below a predetermined chamber 11, the

no with . The balance of the system is disturbed. Under the weight of the balance bar 9, the hydrostatic pressure in the bellows 5 increases, moving inside the housing 3, it closes the outlet section of the drain 4, the groundwater level rises and the adjustment cycle of the predetermined level repeats.

To adjust the regulator to another characteristic level and stabilize the latter, the position of the chamber 11, which acts as a level sensor, is changed by means of an adjusting screw 18, terminated by block 19, by raising or lowering it.
