Изобретение относитс к автоматике и телемеханике, а именно к pasделу регулировани уровн воды, например , на гидротехнических кангшах или оросительных системахоThe invention relates to automation and telemechanics, in particular to a water level control section, for example, on hydraulic tanks or irrigation systems.

Цех(ыо изобретени вл етс повышение надежности устройства при налчии волнени поверхности нижнего бъефа.,The workshop (invention) is to increase the reliability of the device while sweeping the surface of the lower bay.

На фиг. 1 изображено устройс гво момент подачи воды в верхний бьеф; на фиг. 2 - то же, в момент включени в работу и заполнении н -окнего бьефа; на фиг. 3 - то же, в момент выключени при заполненном нижнем бьефе; на фиг, 4 - сифоны устройств изометри .FIG. 1 shows a device for water supply to the headwater; in fig. 2 - the same, at the moment of putting into operation and filling the n-pool; in fig. 3 - the same at the moment of shutdown with a full downstream; FIG. 4 — siphons of isometric devices.

Устройство содерлсит зар дный сифон 1, рабочий сифон 2, горлови которого соединена первым гибким трубопроводом 3 с диффузором 4, раз . мещенным в нижнем бьефе на уровне заданной отметки. Под диффузорсм 4 размещена чашеобразна емкость 5 со сливным каналом 6. В чашеобразной .емкости 5 размеш1ен нижний торец диффузора. Устройство содержит втрой гибкий трубопровод 7, входной патрубок которого размещен в донной части верхнег бьефа, а выходной патрубок под диффузором 4 и встречно ему, причем он укреплен в вилке 8 при помощи стопорных болтов 9. Вилка 8 установлена в ооойме 10 со стопорным болтом 11 ч штоком 12. Сифоны 1 и 2 соединены отверстием 13.The device contains a charge siphon 1, a working siphon 2, the throats of which are connected by the first flexible pipe 3 to the diffuser 4 times. in the downstream at the level of the set mark. Under the diffuser 4 there is a bowl-shaped container 5 with a drain channel 6. The lower end of the diffuser is placed in the bowl-shaped container 5. The device contains a triple flexible pipe 7, the inlet of which is located at the bottom of the upper pool, and the outlet of the diffuser 4 and opposite it, and it is fixed in the plug 8 using locking bolts 9. The plug 8 is installed in the joint 10 with a locking bolt 11 h rod 12. Siphons 1 and 2 are connected by a hole 13.

Устройство работает следующим образом, ,The device works as follows,

Через зар дный сифон 1j второй гибкий трубопровод 8 в нижний бьеф гидросооружени посто нно переливаетс вода из верхнего бьефа. ПриThrough the charged siphon 1j, the second flexible pipe 8, water from the upstream pool is continuously poured into the downstream hydraulic structure. With

Claims

In this case, the air from the strips: these working siphons 2 are carried out through the charging opening 13 by means of the siphon 1 to the lower pool. The living section of the diffuser 4 is blocked by the water horizon in the tank 5, which is full of water flowing from the outlet 7 of the second flexible pipe 7, The cavity of the working siphon 2 is created, a certain discharge, the UV of the water in the throat of the working 2 siphon is annihilated and it is absorbed by its overflow through the throat of the working siphon 2 into the bay. After removal of water from the air cavity of the working siphon 2, the latter begins to work nonHbtt-i section. When water is filled downstream to a predetermined mark, the outlet of the second flexible pipe 7 is below the water level and the energy of the fountain is extinguished by a layer of water above it. The water from the cup-shaped container 5 through the drain channel 6 is drained, the opening of the diffuser 4 is slightly opened and the air through the first flexible conduit 3 is sucked from the atmosphere into the cavity of the working siphon 2 and reduces the discharge in it. decreases When the water level in the pool is lowered, the fountain from the outlet of the second flexible pipe 7 again floods the water into the tank 5 and the water surface blocks the opening of the diffuser 4. At that, in the cavity of the working siphon 2 again AET discharge voltage and the water flow rate therethrough is increased, etc. If it is necessary to change the water mark in the downstream, the locking bolt 11 on the yoke 12 is loosened and the plug 8. With the help of 31 locking bolts 9 fixed to it with a diffuser and a tank 5, the rod 12 moves along. and secured at a desired height with a stopper bolt 11, claims the tail is at the level of a given mark, the second flexible pipeline, the inlet 85 of which is located at the bottom of the upper reach, and the outlet under the diffuser and opposite it, so that, in order to increase the reliability of the device in the presence of waves on the downstream surface, it contains a bowl-shaped tank with a drain channel in which the lower end of the diffuser is located, the outlet of the second flexible pipe being placed with the possibility of filling the bowl-shaped tank angle to the outlet of the first flexible pipe.
