The utility model adopts motor driving wheel rotation, the situation of leaking water in simulating reality; Adopt regulated power supply to control motor rotary speed, realize thus wheel speed speed and regulate.The utility model can be simulated low flow velocity and the high flow rate that produces current, for the detection of follow-up electric water meter gauge outfit provides effective water-flow signal.The utility model is as the supplier of aqueous stream source signal, for guaranteeing that the quality of electric water meter gauge outfit provides requisite basic guarantee.
Accompanying drawing explanation
Fig. 1 is theory structure schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises that motor base to be detected 1, motor 2, water meter turbine 4, magnet ring 5, gauge outfit height regulate parts, power supply 11 and gauge outfit to be checked 7.Motor 2 is fixedly mounted on motor base 1, makes the output shaft 3 of motor 2 stand on this base plane; Water meter turbine 4 and magnet ring 5 are installed on the output shaft 3 of motor, and rotate around its axle center, and magnet ring 5 is directly over water meter turbine 4; For supporting and fix gauge outfit 7 to be checked and regulating this gauge outfit and the gauge outfit height of magnet ring 5 spacings adjusting parts are uprightly arranged on motor base 1; Power supply 11 is connected with the power end of motor 2 by cable 10.
Some magneto-dependent sensors are equipped with in gauge outfit to be checked 7 inside, these magneto-dependent sensors are all arranged in the one side relative with magnet ring, be positioned at directly over magnet ring 5 vertical, for the magnetic field information converting of this magnet ring of induction is converted to electric signal, for the signals collecting of follow-up test and.
Gauge outfit height regulates parts to comprise pallet 6, horizontal strut 8 and vertical rod 9, and pallet 6 can be arranged in vertical rod 9 up or down by horizontal strut 8.Gauge outfit height regulates parts to support on the one hand and fix the position of gauge outfit 7 to be checked, regulates on the other hand the distance between this gauge outfit and magnet ring 5, and while guaranteeing to detect, gauge outfit 7 to be checked can correctly receive useful signal.
Pallet adopts to be guaranteed sensor energy normal examinations and the support of gauge outfit 7 to be checked and fixes the pallet 6 of this gauge outfit.Pallet 6 should adopt non-magnetic material to make, in order to avoid disturb or destroy the magnetic field that magnet ring rotates to form; Its bottom surface can be solid shape, open circles ring-type or latticed.
The ring-shaped magnet of the Ferrite Material of the multipole magnetization mode of two pairs of magnetic poles of magnet ring 5 employings, for converting the situation of leaking water in the magnetic field of rotation.
Power supply 11 adopts regulated power supply; Change power positive cathode and realize the forward and reverse of motor 2.During test, by changing the height of these power supply 11 output voltages and low, realize the fast and slow of motor 2 rotating speeds, thus the different in flow rate of simulated flow.When needs are simulated the water-flow signal rotating and reverse, only need the both positive and negative polarity wiring of transposing motor 2, just the rotation direction of energy switching motor 2.
The simulated flow signal that the utility model provides, for the abundant checking in the function of metering, communication aspects of the gauge outfit of electric water meter, provides effective guarantee.
