Description

В известных водомерах дл  открытых русел, снабженных щитами, перегораживающими часть живого сечени  русла, не обеспечиваетс  посто нство расхода воды через водосливы при изменени х ее уровн .In the known water meters for open channels, equipped with shields, blocking part of the living section of the channel, the flow of water through weirs during the changes of its level is not ensured.

Предлагаемый водомер лищен этого недостатка. Сущность его заключаетс  в применении, вместо щита, отрезка пр моугольной трубы, в противоположных стенках которой имеютс  трапецеидальные водосливы , обеспечивающие свободный перелив воды и посто нный коэффициент расхода. Эта труба удерживаетс  на плаву поплавками, а величина погружени  порогов водосливов под горизонт воды регулируетс  винтовыми подъемниками. Последнее обеспечивает посто нство расхода воды через водосливы независимо от изменени  ее уровн .The proposed water meter lishchen this drawback. Its essence is to use, instead of a shield, a segment of a rectangular pipe, in the opposite walls of which there are trapezoidal weirs, ensuring free flow of water and a constant flow coefficient. This pipe is kept afloat by floats, and the magnitude of the immersion thresholds submerged below the water horizon is controlled by screw lifts. The latter ensures the constancy of the flow of water through weirs regardless of the change in its level.

На чертеже показана схема водомера.The drawing shows a diagram of a water meter.

Водомер состоит из поддерживаемого на поверхности воды поплавками 1 пр моугольного бездонного  щика (отрезка пр моугольной трубы ) 2, противоположные стенки которого имеют вырезы трапецеидальной формы под углом 104° к горизонту. Ящик соединен манжетой 3 из водонепроницаемой ткани с дюкером 4, соедин ющим основной канал с ответвлением. Величина погружени  порогов водосливов под горизонт воды регулируетс  винтовыми подъемниками 5.The water meter consists of a rectangular bottomless crate (rectangular tube section) 2 supported on the surface of the water by floats 1, the opposite walls of which have trapezoidal cuts at an angle of 104 ° to the horizon. The box is connected to a cuff 3 of waterproof fabric with a siphon 4 connecting the main channel with a branch. The magnitude of the immersion thresholds submergence below the water horizon is regulated by screw lifts 5.

Дл  отсчета расхода воды на водосливах нанесены мерные рейки (на схеме не показаны).Measuring slats (not shown in the diagram) are applied to read the water consumption on the spillways.

Предмет изобретени Subject invention

Водомер дл  открытых русел, удерживаемый на плаву поплавками и снабженный водосливами, отличающийс  тем, что, с цеьгк ю обес-, печени  посто нства расхода воды через водосливы независимо от изменений ее уровн , он выполнен в виде соединенного с водовыпуском отрезка пр моугольной трубы, две противоположные стенки которой снабжены трапецеидальной формы вырезами и образуют водосливы с порогами , удерживаемыми под горизонтом воды на заданной глубине.Water meter for open channels, kept afloat by floats and equipped with weirs, characterized in that with a low maintenance of the constancy of water through weirs, regardless of changes in its level, it is made in the form of a rectangular pipe connected to the water outlet, two the opposite walls of which are provided with trapezoidal cutouts and form weirs with thresholds held under the water horizon at a predetermined depth.
