Description
Technical field
The present invention relates to a kind of water meter, particularly a kind of water meter that can long-range Data transmission.
Background technology
Liquid seal electronic direct-reading water meter is a kind of directly reading, can realize the water meter of remote reading again, it generally comprises counting mechanism, impeller metering mechanism, described counting mechanism comprises full liquid-sealing water meter character wheel box and optical-electric module, in the character wheel box, be provided with character wheel, in the electronic module box, be provided with optical-electric module, edge at character wheel is provided with mark, optical-electric module is provided with photoelectric sensor, marking signal and signal exported to the outside by transmission line on the photoelectric sensor induction character wheel, the electronic module box places character wheel box bottom, its character wheel window is open, scale dish and character wheel all are immersed in the special liquid that is poured in the character wheel window, though its sealing better, power-assisted are arranged in character wheel dish clear reading, but because optical-electric module also is sealed in the liquid environment, therefore the seal request height is generally used sealant layer sealed photoelectric module, and the extension line of optical-electric module also will pass this liquid environment of character wheel box through glue strict seal and draw.When adopting the fluid sealant sealing,, cause liquid contact optical-electric module thus and damage these elements owing to fluid sealant long period of soaking easy inefficacy in liquid produced leakage.
Summary of the invention
Technical matters to be solved by this invention is to overcome the above-mentioned deficiency of prior art and a kind of liquid seal electronic direct-reading water meter is provided, make its make simple, seal request is low and good seal performance.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
Liquid seal electronic direct-reading water meter, comprise the counting mechanism of band scale dish, optical-electric module and hydraulic seal character wheel box, with the impeller metering mechanism of going up lower plate, it is characterized in that: described optical-electric module places the character wheel box top of fluid-tight, and separate by the demarcation strip and the character wheel of two side interbands every groove, the electro-optical package of the optical-electric module on top and the character wheel of bottom are placed in demarcation strip separately in the groove of a side and corresponding, on the optical-electric module with character wheel on digital corresponding position opening or transparent is set.
Opening on the above-mentioned optical-electric module is for the numeral on the character wheel of its underpart is seen through, and therefore various ways can be arranged, even can also be that the base plate of optical-electric module is transparent.
For rationally arranging the space, for character wheel is vacated the position, the impeller upper end in the above-mentioned impeller metering mechanism is installed on the lower plate.
Compared with prior art, the invention has the advantages that:
1, by optical-electric module being placed the character wheel box top of fluid-tight; make optical-electric module break away from liquid environment fully; both protected optical-electric module effectively; again under the prerequisite that guarantees clear reading; solve original structure and need adopt the deficiency with the optical-electric module sealing such as special glue-line; and the water meter manufacturing is fairly simple, can enhance productivity, and reduces production costs.
2, because optical-electric module places character wheel box top, and the lead-in wire of optical-electric module just can directly pick out, and lead-in wire is convenient, and only need completely cut off moisture, seal request is low.Simultaneously as long as the sealing that a simple seal just can solve whole optical-electric module space easy, is apace done at the lead-in wire place.
3, the impeller shaft with metering mechanism is installed on the lower plate, can be to the reasonable arrangement of metering mechanism and the numerous parts of counting mechanism, thereby give demarcation strip more space and arranged light electroplax under existing counting mechanism such as the situations such as dial plate, character wheel, four or eight gear wheels and gear train not changing, distribute the space of water meter fully, rationally, effectively.
