Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, a photoelectric counting structure of a high-sensitivity gas meter comprises an intermediate transmission gear 4, a photoelectric sampling gear 5 and a photoelectric sensor 6. The photoelectric sensor 6 is arranged on a main control board 1 on which sampling and metering structural equipment needs to be installed, and the intermediate transmission gear 4 and the photoelectric sampling gear 5 are fixed on the counter support 2; the intermediate transmission gear 4 is meshed with the photoelectric sampling gear 5.
As shown in fig. 3, the photoelectric sampling gear 5 is mounted on the counter support 2, and divides the photoelectric sampling gear 5 into a hollow part 7 and a white plastic part 8 along the center of a circle.
The photoelectric sensor 6 is aligned with the hollow part 7 and the white plastic part 8 of the photoelectric sampling gear 5, and when the photoelectric sampling gear 5 rotates, the photoelectric sensor 6 continuously receives reflected light and a lightless signal, so that the collected optical signal is converted into an electric signal and further processed;
one or more intermediate transmission gears 4 are arranged to convert the mechanical transmission signals of the instrument into optical signals through the photoelectric sampling gear 5; photoelectric sampling gear 5 and intermediate drive gear 4 install on the gear erection column of counter support, and cooperation clamp plate 3 is fixed for simple structure is stable.
As shown in fig. 4, the arrow indicates the light direction, the photoelectric sampling gear 5 is hollow at the hollow part 7, and light can directly pass through from the upper side and can not be reflected, so that the photoelectric sensor 6 can not receive the light; and white plastic or metal at position 8, where light shines from above will reflect light, allowing the photosensor 6 to receive light. The periodic light transmission and reflection converts the mechanical transmission of the photoelectric sampling gear 5 into the light signal received by the photoelectric sensor 6. Because the white part has good light reflection performance and the hollow part has good light passing effect, the photoelectric sampling sensitivity is high, and the photoelectric sampling is stable and reliable.
As shown in figures 5 and 6, the gear mounting column on the counter support adopts a plurality of steps, and the photoelectric sampling gear 5 and the intermediate transmission gear 4 are fixed through the pressing plate 3 after being mounted, so that the structure is simplified. The top end of the gear mounting column can also be fixed by adopting a hot pressing process, so that the number of parts is reduced.
The structure is simple and easy to implement, does not occupy space, and can be applied to the structures of most instruments which need to use photoelectric sampling measurement, such as gas meters, electric meters, water meters, detection devices of precision equipment and the like.
