Description
Technical field
The present invention relates to water meter, particularly relate to a kind of optical fiber direct-reading water meter.
Background technology
In daily life, water meter is seen everywhere, and has become an important component part of people's life.Traditional mechanical water meter gradually replace by photoelectric water meter, the gauge outfit of this photoelectric water meter generally comprises housing 1 and pcb board 2, print wheel component 3 and the ladder be arranged on respectively in housing 1 enters wheel assembly 4, and on pcb board 2, the both sides of each character wheel 3a of corresponding print wheel component 3 are respectively equipped with the infraluminescence pipe and infrared receiving tube that cooperatively interact.During its work, the notch that the infrared electro signal that infraluminescence pipe sends is perforated through on character wheel 3a is received by the infrared receiving tube matched, meanwhile, this infrared receiving tube is by this information transmission to controller, and decoding of information is just generated reading through certain algorithm by controller.
The gauge outfit of the photoelectric water meter of this structure, when designing, for avoiding water to contact with infrared receiving tube with pcb board 2, infraluminescence pipe, has added one piece by pcb board 2, infraluminescence pipe and infrared receiving tube and the completely isolated transparent glass cover of water in housing.Like this, this photoelectric water meter is caused to there is following problem when reality uses:
1, the infrared electro signal sent due to infraluminescence pipe need first penetrate layer of transparent cloche, penetrate the notch (i.e. WATER AS FLOW MEDIUM) on character wheel 3a again, finally also to penetrate layer of transparent cloche could be received by infrared receiving tube, so in the use procedure of water meter, the high grade of transparency of transparent glass cover must be remained.But water meter in use for some time, the surface that transparent glass cover contacts with tap water is very easy to form one deck scale, and this scale can have a strong impact on the normal transmission of infrared electro signal, thus causes water meter normally to work.Scale is formed for avoiding transparent glass cover surface, the position of general meeting corresponding housing 1 on the print wheel shaft of print wheel component 3 adds O-ring seal, make the space sealing between housing 1 and transparent glass cover, and distilled water is poured between housing 1 and transparent glass cover, like this, due to this distilled water and ducted tap water completely isolated, and distilled water can not produce scale, so well solve the problem that transparent glass cover surface easily forms scale.But the O-ring seal added can increase the rotational resistance of the print wheel shaft of print wheel component 3, thus the sensitivity that the print wheel shaft reducing print wheel component 3 rotates, and then also reduce the sensitivity of water meter;
2, because the infraluminescence pipe of character wheel 3a both sides and infrared receiving tube are isolated by transparent glass cover, so the spacing between the infraluminescence pipe of character wheel 3a both sides and infrared receiving tube is larger, like this, more once the bubble in WATER AS FLOW MEDIUM, the infrared electro signal that infraluminescence pipe sends just is difficult to be received by infrared receiving tube, thus have impact on the reading of water meter.
