The utility model relates to a non-contact magnetic drive water gauge code wheel device is used in the water gauge. When in use, the device is arranged in the water meter and used for realizing clear counting of the water meter.
Fig. 1 shows a schematic structural diagram of a non-contact magnetic drive water meter code wheel device of the present invention. As shown in fig. 1, the non-contact magnetic-driven water meter code wheel device of the present invention includes a driving wheel cavity 1 and a driven wheel cavity 2. The driving wheel cavity 1 and the driven wheel cavity 2 are mutually separated and are arranged opposite to each other.
Wherein, a driving wheel 3 is arranged in the driving wheel cavity 1. And a first permanent magnet 4 is arranged on the left side surface of the driving wheel 3, and a connecting shaft 5 is arranged on the right side surface. The connecting shaft 5 extends out of the driving wheel cavity 1 and is connected with the connecting disc 6. The connecting disc 6 is used for connecting an impeller transmission mechanism of the water meter. Thus, the rotation of the impeller of the water meter will drive the driving wheel 3 to rotate.
The utility model discloses in, first permanent magnet 4 with action wheel 3 sets up as an organic whole, makes first permanent magnet 4 can be along with action wheel 3's rotation rotates. Meanwhile, the first permanent magnet 4 is arranged in the driving wheel cavity 1, so that the influence of the outside is avoided, and the accuracy of counting can be ensured.
The follower wheel cavity 2 is internally provided with a character wheel shaft 7. For example, two ends of the word wheel shaft 7 are respectively and fixedly installed on the left side plate and the right side plate of the follower wheel cavity 2. The character wheel shaft 7 is provided with a low-order character wheel 8, a high-order character wheel 10 and a plurality of middle-order character wheels 11 positioned between the low-order character wheel 8 and the high-order character wheel 10. The circumferential surfaces of the low-order character wheel 8, the high-order character wheel 10 and the middle-order character wheel 11 are uniformly provided with numbers 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. The lower character wheel 8, the upper character wheel 10, and the middle character wheel 11 are rotatable on the character wheel shaft 7.
Wherein, according to the needs of counting, can install 3-6 said median character wheel 11 on the said character wheel axle 7, like this, the whole counting structure has 5-8 character wheels altogether. Preferably, 4 middle position character wheels 11 are installed on the character wheel shaft 7, so that the whole counting structure has 6 character wheels, and the counting structure is similar to that of a common water meter.
And a second permanent magnet 9 is arranged on the right side surface of the low-position character wheel 8. The low-position word wheel 8 and the second permanent magnet 9 are integrated, so that the low-position word wheel 8 can rotate along with the rotation of the second permanent magnet 9. The second permanent magnet 9 is opposite to the first permanent magnet 4, and the polarity of the second permanent magnet 9 is opposite to that of the first permanent magnet 4.
Like this, the rotation of the impeller at the water gauge drives when the action wheel 3 rotates, first permanent magnet 4 then action wheel 3 rotates, because first permanent magnet 4 with strong magnetic attraction has between the second permanent magnet 9, the rotation of first permanent magnet 4 will drive second permanent magnet 9 rotates, and then passes through the rotation of second permanent magnet 9 drives low level character wheel 8 rotates to reach the driven purpose of non-contact. Meanwhile, the magnetic force is utilized to drive the non-contact rotating wheel, so that transmission errors cannot be generated, and the accuracy of counting can be ensured.
And a bearing pin shaft 12 is also arranged in the cavity 2 of the follow-up wheel. For example, two ends of the bearing pin 12 are respectively and fixedly mounted on the left and right side plates of the follower wheel cavity 2. The bearing pin 12 is provided with a plurality of carry cones 13. The carry cone 13 is rotatable on the bearing pin 12. The carry roller 13 is used for realizing transmission between the low-order character wheel 8 and the middle-order character wheel 11, between the middle-order character wheel 11 and the middle-order character wheel 11 (that is, between two adjacent middle-order character wheels 11), and between the middle-order character wheel 11 and the high-order character wheel 10.
Specifically, the number of carry cones 13 is determined according to the number of character wheels (i.e., the total number of the lower character wheel 8, the upper character wheel 10, and the middle character wheel 11). That is, the number of the carry cones 13 is one less than the number of the character wheels. For example, with 6 wheels, there would be 5 cones, with 7 wheels, there would be 6 cones, with 8 wheels, and with 7 cones.
In the present invention, as shown in fig. 2, a driving gear 15 is provided on the left side surface of the low position character wheel 8 and the middle position character wheel 11. And a driven gear 14 is arranged on the right side surface of the high-order character wheel 10 and the middle-order character wheel 11.

And, the carry bit 13 is provided with a carry bit. One end of the carry gear of the carry cone 13 is engaged with the teeth of the driving gear 15, and the other end is engaged with the teeth of the driven gear 14. Thus, the rotation of the driving gear 15 rotates the driven gear 14 through the carry roller 13.
In the present invention, it is preferable that the ratio of the number of teeth on the driving gear 15 to the number of teeth on the driven gear 14 is 1: 10. More preferably, as shown in fig. 4, the number of teeth on the driving gear 15 is two. As shown in fig. 3, the number of teeth on the driven gear 14 is twenty.
Thus, when the low level wheel 8 rotates, the drive gear 15 on its left side follows it. Since the driving gear 15 has only two teeth, the low position character wheel 8 rotates one circle, and the driving gear 15 contacts the carry gear 13 twice and drives the carry gear 13 to rotate twice, so that the carry gear 13 can only drive the driven gear 14 to rotate twice. Because the driven gear 14 has twenty teeth, the low position character wheel 8 can rotate 1 circle only when rotating 10 circles, and the middle position character wheel 11 adjacent to the low position character wheel can rotate 1 circle. Similarly, the right middle character wheel 11 rotates 10 circles, and the left middle character wheel 11 adjacent to the right middle character wheel can rotate 1 circle. And, the leftmost middle character wheel 11 rotates 10 times, and the high character wheel 10 can rotate 1 time. Thus, the purpose of accurate counting is achieved.
