Description
(1) technical field
The utility model relates to a kind of water meter, particularly one reflective classification direct-reading liquid-sealing water meter.
(2) background technology
Under current technology, combustion gas, water, ammeter etc. all have the function of direct-reading teletransmission, no longer need the person's of checking meter manual metering from house to house, and the sensor that only need be arranged on table can teletransmission input computing machine.Be generally used for the gauging table measuring the flows such as gas, liquid, electricity, its principle of work is by the detection flow apparatus in instrument by gas, liquid, dielectric, detect flow apparatus and drive gearing, reading disk is driven to rotate by gearing again, when reading dial being arranged character code, reflected by character code by the amount of spin on reading disk.But, this mode is all generally determined the numerical value of this character wheel by a gear, because a disk has 360 °, and numerical value when accurately cannot judge its carry status from a gear merely, cause read untrue, accumulate over a long period and may cause larger mistake.
(3) summary of the invention
The utility model in order to make up the deficiencies in the prior art, provide a kind of structure simple, be convenient to the reflective classification direct-reading liquid-sealing water meter that manufactures and install, accuracy of reading rate is high.
The utility model is achieved by the following technical solution:
A kind of reflective classification direct-reading liquid-sealing water meter, comprise some character wheels, character wheel cambered surface both sides are provided with the first annulus and the second annulus successively, it is characterized in that: on described first annulus, half region is clear area, and second half region is shadow region; On the second annulus corresponding to clear area on first annulus, half is shadow region, and second half is clear area, and shadow region is positioned at the counter clockwise direction of clear area; On the second annulus corresponding to shadow region on first annulus, half is shadow region, and second half is clear area, and shadow region is positioned at the counter clockwise direction of clear area.
The side of described second annulus is provided with four first sensors, the central angle that line between every two adjacent first sensors and the center of circle of the second annulus forms is 36 °, the side of the first annulus is provided with two the second sensors, and the central angle that the line between two the second sensors and the center of circle of the first annulus forms is 90 °.
Described first sensor is positioned at the center of circle of the second annulus, and to be the center of circle circumferentially same, and the second sensor is positioned at the center of circle of the first annulus, and to be the center of circle circumferentially same.
Described character wheel center is respectively equipped with through hole.
Can the beneficial effects of the utility model be: be reflected by sensor outgoing signal, determine code combination, and classification is compared and reached a conclusion; Structure is simple, be convenient to manufacture and install, accuracy of reading rate is high, cost is low, and huge contribution has been made in the metering for discharge.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is that character wheel cambered surface of the present utility model launches schematic diagram;
In figure, 1 character wheel, 2 first annulus, 3 second annulus, 4 clear areas, 5 shadow regions, 6 first sensors, 7 second sensors, 8 through holes.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises some character wheels 1, and it is clear area 4 that character wheel 1 cambered surface both sides are provided with half region on the first annulus 2 and the second annulus 3, first annulus 2 successively, and second half region is shadow region 5; On the second annulus 3 corresponding to clear area 4 on first annulus 2, half is shadow region 5, and second half is clear area 4, and shadow region 5 is positioned at the counter clockwise direction of clear area 4; On the second annulus 3 corresponding to shadow region 5 on first annulus 2, half is shadow region 5, and second half is clear area 4, and shadow region 5 is positioned at the counter clockwise direction of clear area 4.The side of the second annulus 3 is provided with four first sensors 6, the central angle that line between every two adjacent first sensors 6 and the center of circle of the second annulus 3 forms is 36 °, it is 90 ° that the side of the first annulus 2 is provided with the central angle that the line between two the second sensors, 7, two the second sensors 7 and the center of circle of the first annulus 2 forms.First sensor 6 is positioned at the center of circle of the second annulus 3, and to be the center of circle circumferentially same, and the second sensor 7 is positioned at the center of circle of the first annulus 2, and to be the center of circle circumferentially same.Character wheel 1 center is respectively equipped with through hole 8.
Adopt one of the present utility model reflective classification direct-reading liquid-sealing water meter, character wheel 1 is installed in rotating shaft respectively by through hole 8, and the flowing of water drives rotating shaft to rotate, thus drives character wheel 1 to rotate, to record flow.When having water flow, first annulus 2 and the second annulus 3 are also rotate, but first sensor 6 and the second sensor 7 are static, when after rotation, first sensor 6 is by the scanning to the shadow region 5 on the second annulus 3 and clear area 4, to scan clear area 4 for 0, scanning shadow region 5 is 1, just can show that one group with the code of 0 and 1 composition, amount to 5 kinds, second sensor 7 is by the scanning to the first annulus 2 top shadow district 5 and clear area 4 simultaneously, same to scan clear area 4 for 0, scanning shadow region 5 is 1, show that one group with the code of 0 and 1 composition equally, amount to 4 kinds, the two combination just has 20 kinds of possibilities, according to the first annulus 2 on character wheel 1 and the shadow region 5 of the second annulus 3 or the division of clear area, finally can determine the numeral of 0 ~ 9 wherein representated by 20 groups of codes.
