Description
[technical field]
The utility model relates to a kind of water meter volumetric measurement device, refers in particular to a kind of device of finishing container glass pipe level measuring automatically.
[background technology]
The glass tube level measuring is widely used in the water meter volumetric method and detects industry, and present calibration method is manually carried out, and the staff manually reads water level and these data of manual record with eye, by hand the data input computer is convenient to file and write down and print then.Artificial a large amount of repeatedly reading of data unavoidably can be brought certain personal error.Therefore, there are a lot of shortcomings such as workload is big, efficient is low, precision is low, personal error is big, verification result is not objective in it.
[summary of the invention]
The purpose of this utility model is to have overcome above-mentioned defective, adopts glass tube water level surface characteristics, and a kind of photoelectric technology of utilizing is provided, and reliably accurately measures the simple device of glass tube water level.
The purpose of this utility model is achieved in that a kind of automatic water level measurement device, it is characterized in that: it comprises support, and support is fixed on the testing container glass tube; Be arranged with leading screw in parallel with the testing container glass tube on the support, be socketed with the photoelectric sensor that is used to detect water surface site in the testing container glass tube on the leading screw; The leading screw upper end links to each other with driving motor, is with anti-dazzling screen on the leading screw termination therebetween, and anti-dazzling screen and optoelectronic switch constitute pulse producer; The support lower end is provided with limit switch;
Described photoelectric sensor is made of corresponding light emitting diode and the photoelectric receiving tube that is provided with on the U-shaped jaw;
Described anti-dazzling screen is circular, on it by being evenly distributed in eight perforates;
Described motor is a direct current generator;
Parallel leading screw both sides also are provided with for photoelectric sensor and wear the guide rod that slides on it on its frame.
Than common water level detecting, the utility model is simple in structure, stable performance, precision height, easy to use, verification result is objective, and read the glass tube level measuring can full automatic advantage.
[description of drawings]
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is a side structure synoptic diagram of the present utility model.
Fig. 2 is the structural representation of the utility model photoelectric sensor.
Fig. 3 is Facad structure figure of the present utility model.
Fig. 4 is the anti-dazzling screen structural representation of the utility model pulse generating unit.
[embodiment]
As Fig. 1, Fig. 2, Fig. 3 automatic water level measurement device of the present utility model comprises support 1, support 1 is fixed on volume glass tube 12 tube walls to be measured.Support 1 corresponding volume glass tube 12 is arranged with leading screw 3 in parallel, is socketed with the photoelectric sensor 7 that is used for water level high detection in the volume glass tube 12 on the leading screw 3; Leading screw 3 upper ends link to each other by shaft coupling 4 with direct current generator 2, be with anti-dazzling screen 5 anti-dazzling screens and pulse producer of optoelectronic switch 6 formations on the termination between leading screw 3 and the direct current generator 2, direct current generator 2 all is fixed in the support 1 with leading screw 3, and the lower end of support 1 is provided with the limit switch 8 that is used to locate photoelectric sensor 7.Also be equipped with on the support and be used for step-by-step counting and the governor circuit 9 of controlling direct current generator 2.
Above-mentioned photoelectric sensor 7 cooperates with leading screw 3 by the nut 11 in it, and its two ends are coated with two guide rods 13 parallel with leading screw 3, and photoelectric sensor 7 can move up and down along guide rod 13 under the drive of leading screw 3.Photoelectric sensor 7 terminations become fork-shaped, afterbody lower end to be provided with to be used for the projection that contacts with limit switch 8, and correspondence is provided with light emitting diode/photoelectric receiving tube 10 on its fork-shaped termination.Referring to Fig. 4, the anti-dazzling screen of described pulse producer is circular, on it by being evenly distributed in eight perforates.
During measurement, behind volume glass tube stable level, governor circuit 9 drives direct current generator 2, drive screw mandrel 3 despinings, thereby at first begin to detect and begin to count the pulse that produces by anti-dazzling screen 5 and optoelectronic switch 6 from bottom limit switch 8 by the cooperation drive pick-up unit 7 of leading screw 3, nut 11.Direct current generator 2 drives leading screw 3 again and is rotated in the forward rising then, leading screw 3 drives the shading disk 5 on it and passes through optoelectronic switch 6 detections and produces eight square-wave pulses in this process, when photoelectric sensor 7 runs to the water level place, because water level forms concave surface in glass tube, light had refraction action, photoelectric receiving tube 14 produces a pulse signal to the light of this variation, control motor 2 stopped the rotation after governor circuit 9 received this signal, thereby the stop pulse counting, governor circuit 9 is sent out this umber of pulse simultaneously by communication interface.Photoelectric sensor 7 counter motions after the driven by motor are finished in measurement, stop behind support 1 bottom limit switch 8.On behalf of how many volumes, ppu convert according to counting umber of pulse and a screw mandrel pitch, finally calculates the volume of water.
This device screw mandrel measurement range, screw mandrel pitch can change according to actual conditions, near the general glass tube scale is arranged, can simply learn the water body product of a pitch representative of screw mandrel, the photoelectric sensor start position is relative with scale one integer number to be determined by limit switch.
It is to be noted; of the present utility modelly be not limited to above-mentioned embodiment; any simple modification, equivalent variations and modification that any those skilled in the art do the foregoing description in based on technical solutions of the utility model all belong in the protection domain of the utility model number.
