Abstract

The invention relates to the field of hydraulic engineering, in particular, to automatic control of the upper and lower pools of gyrotechnical facilities, and can be used mainly in land reclamation systems. The device contains a shield with a culvert opening installed between the upper and lower pools, in which a downward branch of the siphon is installed, equipped with an air discharge tube. The inclusion of a float chamber in the device, provided with a drain channel, the overlapping of which is controlled by the float sensor, fixing the end of the air tube on the float chamber reduces the force required when the target level is changed. 1 il. about

The invention relates to hydraulic engineering, namely to automatic controls of the water levels of the upper and lower pools of hydraulic structures, and can be used mainly in land-reclamation systems.

The purpose of the invention is to reduce the required effort when changing the level of a given downstream "

The drawing shows a device for adjusting the level of water.

The device is installed between the upper and lower pools on the flybet 1 shield 2 with a water cone hole 3, in which the downward branch of the siphon 4 is installed. In the downward branch of the siphon there is a hole 5 5 located HI-DKG of the minimum water of the upstream, To the siphon’s mouth 4 an air-tube bending tube b is attached, attached to the body of the water-filled float 7, the water-filled float 7 is connected to the atmosphere through the hole 8s with the upper buoy through the hole 9, the device holds the chamber 10. communicates The water supply float 7 is equipped with a drain channel made of a flexible tube 12, which has a valve 13, made in the form of a lever 14 with a horizontal axis of rotation 15. The valve 13 is connected via a cable 16 from the ends of the rocker arm 17; On the other end of the rocker arm 17, the block 19 is fixed for winding and fixing the cable 20. The linking rocker arm with the float sensor 21 is level Bracket 22 by means of hinges 23 connects the water-filled float 7 with shield 2f On shield 2 the bracket 24 is fixed free moving

in the vertical plane of the strap 25, clamps 26 are used to fix the strap 25 in a predetermined position. The lengths of the strap 25 and the bracket 22 are more than one and the strap 25 is positioned below the bottom of the siphon 4 "

the length of the cable 20, which is wound on the block 19.

At a given water level in the downstream, the valve 13 is open, since the dimensions of the opening 9 to the tube 12 select the Tash-1 image; so that the flow through tube 12 is greater than through the hole, there is no water in the water-filled float 7, and the inlet end of the air tube 6 is located above the water level of the upstream. When the water level in the downstream is lowered, the water level in chamber 10 is lowered,

The float level sensor 21 is lowered, turning the rocker arm 17 ", which causes the outlet of the tube 12 to overlap with the valve 13. Water fills the water-filled float

It enters the inlet end of the air tube 6. In this case, the siphon 4 is insulated from access of atmospheric air. The water jet5 entering the downward branch of the siphon 4 through the opening 5s captures the air from the siphon 4 and brings it to the NIZHN1-P pool, causing this vacuum to appear in the siphon 4, the Siphon 4 is activated by a full cross section and ensures the discharge of water from the upper downstream in NRSHNY POS. Restoration of a given level of 28 Hi-Fowl float sensor / level 21 floats, valve 13 opens and water flows through the flexible pipe 12 to the lower reach. At the same time, the water-filled float 7 is facilitated, by splitting, withdrawing from the EODT the inlet end of the air conductor twebki 6,

The air enters the siphon 4 through the air pipe -6, the vacuum breaks down, and the water supply is stopped by the siphon 4 of the long reach. When the water level of the upstream water supply level increases, the float 7 rises and abuts against the plan /.5. This further end in:;; duct pipe 6 turns out to be flooded. As a result, the siphon of the air siphon is removed by a stream of water through the hole 5 and the siphon is charged to discharge water through the siphon downstream recovery this level of the upstream water filled float 7 WHO-Vraca aets original position Poi this inlet end voz.auhopro 12871
