. . The invention relates to hydraulic engineering, in particular, to a device for adjusting the water level in hydraulic structures with tubular outlets, mainly prevalent in rice irrigation systems, and is an improvement on the known device according to the basic model. St. No. 1221640.

The purpose of the invention is to improve the speed and reliability of the controller.

The drawing shows schematically the proposed controller, the section along the longitudinal axis.

The level regulator includes the upper .1 and lower 2 pools, interconnected by a tubular water outlet 3, weir 4 with cap 5, and hydrocyclone 6, which is a vacuum source, with supply 7 and drain 8 nozzles, and with Peskov nozzle 9, connected hydrocyclone 6 with a cavity of the cap 5. The cavity of the cap 5 is connected with the atmosphere by a tube 10, the outlet of which is fixed on the lever 11. The lever 11 is equipped with a hinge 12, and the float level sensor 13 - with a movable hinge 14.

The device works as follows.

When the level reaches the upper reach 1 above the end of the tube 7, water enters the lower reach 2 through the hydrocyclone 6. Due to the occurrence of a vacuum in the hydrocyclone, the suction of air from the cavity of the hood 5 begins through the sand cyclone 5. If.

in the downstream 2 the water level does not reach a predetermined value, then the end of the tube 10 is lowered into the water, air enters the cavity of the cap 5

not. The cap, together with the weir 4, performs the function of a siphon, which in this mode is charged, and filling of the lower pool begins.

When water passes through the tubular outlet 3, a vacuum is formed at its inlet. In the zone of formation of a vacuum, a drain pipe 8 of a hydrocyclone 6 is installed, which contributes to an increase in the suction of water from the hydrocyclone 6 and a greater generation of vacuum by it.

When the preset mark reaches the lower reach, which is established by means of the displaced hinge 14, the float sensor 13 of the level fixed on the lever 11 by means of the hinge 12 pops up and. the outlet of the tube 10 rises, together with the cavity of the cap 5 with the atmosphere. The pressure under the cap 5 rises, and the flow through it decreases or stops, then the cycle repeats.

F o r m a la invention

Water level regulator in the pools of hydraulic structures according to ed. St. No. 1221640, distinguishing and - with the fact that, in order to increase the speed and reliability of the regulator, the outlet of the hydrocyclone drain pipe is connected to the reduced pressure zone.

Claims (1)

Claim The water level regulator in the headwater of hydraulic structures according to ed. St. No. 1221640, characterized in that, in order to increase the speed and reliability of the regulator, the outlet of the drain pipe of the hydrocyclone is in communication with the reduced pressure zone.
