Description
В предлагаемом устройстве дл измерени скорости течени в открытых потоках при помощи поплавков во врем исследований поверхностных струй на модел х гидросооружений в гидротехнических лаборатори х, над поверхностью потока расположена решетка, с одной стороны которой установлена фотопластинка , а с другой фотоэлемент. При движении поплавка, несущего источник света, фотопластинка регистрирует траекторию движени поплавка, а фотоэлемент-скорость его.In the proposed device for measuring the flow velocity in open streams using floats during surface jet studies on hydraulic structures in hydraulic engineering laboratories, a grating is located above the flow surface, on one side of which a photoplate is installed and on the other is a photocell. When the float is moving, carrying a light source, the photographic plate records the trajectory of the float, and its photocell shows its speed.
чНа чертеже изображена схем устройства дл измерени скорости течени в открытых потоках.Fig. 1 shows diagrams of a device for measuring flow rates in open streams.
Камера устройства состоит из двухThe device’s camera consists of two
.отделений, верхнего с фотоэлементом 7branches, top with photocell 7
И нижнего-с обычным объективом 5,And the bottom one with a conventional lens 5,
расположенных над поверхностью потсжа.located above the surface of Potszha.
Оба отделени разделены решеткой ,Both compartments are separated by a grid.
просветы которой представл ют собойthe lumens of which are
; поперечники потока исследуемой модели, перенесенные за фотопластинку 3, установленную под нижней стороной решетки 2. При прохождении по потоку поплавка 6, несущего источник света, например , свечку, его траектори , как обычно, фиксируетс на фотопластинке 5, а в момент прохождени изображение источника света через щель решетки 2 освещаетс фотоэлемент /, дающий импульс тока, который через соответствующее реле записываетс прибором, регистрирующим скорэость движени поплавка .; The flow diameters of the model under study transferred for a photographic plate 3 installed under the bottom of the grid 2. When a float 6 carrying a light source, such as a candle, passes through the stream, its trajectory, as usual, is fixed on the photographic plate 5, and through the slit of the lattice 2, a photocell is illuminated, giving a current pulse, which is recorded by a device registering the speed of the float through the corresponding relay.
Предмет изобретени .The subject matter of the invention.
Устройство дл измерени скорости течени в открытых потоках при помощи поплавков, отличающеес тем, что над поверхностью потока расположена решетка 2, с одной стороны которой установлена фотопластинка дл регистрации траектории движени несущего источник света поплавка б, а с другой стороны-фотоэлемент дл регистрации скорости движени поплавка.A device for measuring the flow velocity in open streams using floats, characterized in that a grating 2 is located above the flow surface, on one side of which there is a photographic plate for recording the movement trajectory of the carrier light source b and, on the other side, a photocell for detecting the speed of float movement .
