Description
В гидротехнических лаборатори х при исследовании поверхностных струй на модел х гидросооружений часто пользуютс поплавками, скорость коих определ ют секундомером на глазок. In hydrotechnical laboratories, when studying surface jets on models of hydraulic structures, floats are often used, the speed of which is determined by a stopwatch per eye.
Дл уточнени этой операции в предлагаемом устройстве дл измерени скорости течени в открытых потоках при помощи поплавков над поверхностью потока нат нуты проволоки, расположенные перпендикул рно к направлению течени и параллельно друг другу и сое ШДйнёнйь1ё t одним из полюсов электри Чё кой сети.

The floats are equipped with a cone HH f Negmy stems, when contacting 1 with wires including 1% 1% of the device, the time flow is indicated; - contact.

с контактными стерженьками-волосками 26. При прохождении поплавка под проволокой 21 (фиг. 1) контактные стерженьки-волоски 26 соприкасаютс с проволокой , замыкают через жидкость электрическую цепь и включают прибор, регистрирующий моменты времени соприкосновени .with contact hairs 26. When the float passes under the wire 21 (Fig. 1), the contact hairs 26 contact with the wire, close the electrical circuit through the liquid and turn on the device that records the time of contact.
Прибор снабжен барабаном / (фиг. 1, 2), приводимым во вращение часовым механизмом 6 с гирей 72, и центробежным регул тором 7. Механизм 6 отрегулирован с достаточной точностью так, чтобы устранить необходимость дополнительного контрол времени.The device is equipped with a drum / (FIGS. 1, 2), a clock mechanism 6 with a weight 72, which rotates in rotation, and a centrifugal regulator 7. The mechanism 6 is adjusted with sufficient accuracy so as to eliminate the need for additional time control.
Шестеренки 2-сменные с тем, чтобы один оборот барабана длилс 1-10 сек., смотр по необходимости.The gears are 2-interchangeable so that one turn of the drum lasts 1-10 seconds, review as needed.
По черв ку 8, вращение которого св зано с вращением барабана, передвигаетс каретка JO с электромагнитом /7 и стрелкой 9, делающей отметки при ударе на барабане 1 через копировальную бумагу, надетую поверх ленты, помещенной на барабане.The screw 8, the rotation of which is associated with the rotation of the drum, moves the JO carriage with the electromagnet / 7 and the arrow 9, which makes marks on impact on drum 1 through copying paper worn over the tape placed on the drum.
При включении прибора магнит J3 прит гивает собачку 14 и освобождает этим барабан /, который начинает вращатьс . Перва из проволок 27 вл етс таким образом пусковой и в измерении не учитываетс .When the device is turned on, the magnet J3 attracts the pawl 14 and thus releases the drum / which begins to rotate. The first wire 27 is thus starting and is not taken into account in the measurement.
Поплавок проходит последовательно все проволоки и при замыкании токаThe float passes all the wires in series and when the current is closed
