Abstract
The utility model provides an apparatus for measuring the flow speed of river, and adopts the technical proposal that: a screw impeller is arranged in a shell body of the apparatus, a magnet is fixedly disposed on the outer ring of an impeller support, a sensor is mounted on the inner wall of a cyclone body, the magnet and the inner wall of the cyclone body are positioned on the same horizontal line, and a sensor circuit is led out from the shell body and connected with a connecting terminal fixed on the shell. When measuring the flow speed of river, the water flow drives the screw impeller to rotate, the magnet on the screw impeller support will approach the sensor at the same horizontal line for one time when the impeller is rotated by one circle, the sensor then produces one inductive electric pulse, and the inductive electric pulse is transmitted to an electronic display counter through a lead, thereby the flow speed of river is effectively recorded.
Description
One, technical field:
The utility model relates to a kind of measurement river flow velocity device.
Two, background technology:
Mostly there are drawbacks such as precision is not high, use inconvenience in the existing river flow velocity device of measuring, has a strong impact on measurement effect.
Three, summary of the invention:
The utility model is exactly at the problems referred to above, and a kind of measurement river flow velocity device is provided, to improve the degree of accuracy of measuring the river flow velocity.The technical solution of the utility model is: be provided with helical runner in the device case, magnet of fixed installation on impeller support outer shroud, on the rotary fluid inwall, be provided with a sensor, magnet and rotary fluid inwall are on same horizontal line, this sensor circuit is drawn from housing, links to each other with the connection terminal that is fixed on shell.Be provided with threaded connector at water inlet and water delivering orifice place, threaded connector can pass through threaded adjusting inflow and aquifer yield.In use, circuit on the count display is connected with connection terminal on the sensor outer housing, in the process of measuring the river flow velocity, magnet and same horizontal sensor that river stream drive helical runner rotates on the helical runner support that whenever rotates a circle are approaching once, sensor just produces induction electrical pulse one time, this induction electrical pulse imports the electronics display counter into by lead, thereby effectively shows the river flow velocity.
Four, description of drawings:
Accompanying drawing is a structural representation of the present utility model;
1. water inlets among the figure, 2. connection terminal, 3. sensor, 4. magnet, 5. helical runner, 6. threaded connector, 7. water delivering orifice, 8. housing, 9. threaded connector, 10. impeller support.
Five, embodiment:
In device case, be provided with helical runner (5), a fixed installation magnet (4) on impeller support (10) outer shroud, on the rotary fluid inwall, be provided with a sensor (3), magnet (4) and rotary fluid inwall are on same horizontal line, sensor (3) circuit is drawn from housing (8), links to each other with the connection terminal that is fixed on shell (2).Locate to be provided with threaded connector (6) and threaded connector (9) at water inlet (1) and water delivering orifice (7), threaded connector (6) and threaded connector (9) can pass through threaded adjusting inflow and aquifer yield.In use, circuit on the count display is connected with sensor (3) connection terminal (2), in the process of measuring the river flow velocity, the magnet (4) that river stream drive helical runner (5) rotates on helical runner (5) support that whenever rotates a circle is approaching once with same horizontal sensor (3), sensor (3) just produces induction electrical pulse one time, this induction electrical pulse imports the electronics display counter into by lead, thereby effectively shows the river flow velocity.
