Description
Technical field
The present invention relates to a kind of water meter, relate in particular to a kind of liquid sealing photoelectric direct-reading water meter that can long-range Data transmission.
Background technology
Our employed traditional mechanical water meter mainly is divided into three kinds by the working environment of counter at present: dry-type meter, wet-type meter and liquid-sealing water meter.Wherein liquid-sealing water meter is meant that its counting character wheel or whole counter dial are installed in the character wheel box that independently seals, and embedding has special liquid in the box.Sharpness in the counting character wheel of seal or the whole counter dial does not receive the influence of outside water quality, can prevent the character wheel surface long-term use by water quality stained and cause phenomenon smudgy or can't reading.
Liquid sealing photoelectric direct-reading water meter is as base table with the standard machinery liquid-sealing water meter; In liquid-sealing water meter character wheel box, be provided with counting character wheel and optical-electric module; The edge or the side of character wheel have mark, and optical-electric module has photoelectric sensor, and photoelectric sensor can be responded to the formed light signal of figure notation on the character wheel; And convert light signal to electric signal through transmission line output, thereby realize the long-range transmission of measurement data.
The character wheel box of the liquid sealing photoelectric direct-reading water meter that uses at present, mainly contain following dual mode: a kind of is that character wheel and optical-electric module are sealed in the character wheel box together, in the character wheel box, is full of a kind of special liquid, realizes fluid-tight; Another kind of then be the structure that the character wheel box is designed with upper and lower chamber, be provided with the counting character wheel in the epicoele, and the embedding special liquid carries out fluid-tight; Sealing is provided with optical-electric module in the cavity of resorption.The defective of above-mentioned first kind of mode is: the optical-electric module long period of soaking is in solution; And fluid-tight character wheel box has the number wheel shaft that stretches out outside the box; Number wheel shaft is in long-term running work; The box of flowing through outer in liquid can infiltrate in the box inevitably, cause the photo-electronic directly reading module to meet water and can't operate as normal.The defective of the second way is: because optical-electric module mostly self can not waterproof; Promptly can be ineffective after meeting water; Therefore must adopt epoxy resin or other fluid sealants that optical-electric module is sealed in the cavity of resorption of character wheel box, and it is solidified, but because character wheel box cavity of resorption directly contacts the tap water of the water meter of flowing through; Therefore very high to the seal request of glue-line, glue-line is made has the not good or impaired optical-electric module chance water that just possibly cause malfunctioning slightly; In addition; Optical-electric module is enclosed in the fluid sealant admittedly; Are difficult in the reliability of its electronic devices and components performance, stability and serviceable life guarantee, and, can't ascertain the reason when causing optical-electric module to break down because embedding can't be measured after solidifying again; Therefore product also can't improve, and qualification rate can't improve; Simultaneously, its manufacturing process is also very complicated, and production efficiency is very low.
Summary of the invention
The technical matters that the present invention will solve is: the employed fluid-tight character wheel of present liquid sealing photoelectric direct-reading water meter box; Optical-electric module existence in its box is prone to touch the malfunctioning defective of water; In order to overcome this defective, the spy provides a kind of liquid sealing photoelectric direct-reading water meter that can make optical-electric module obtain the protection of essence seal.
The technical scheme that the present invention adopts is: a kind of liquid sealing photoelectric direct-reading water meter; Have the cavity-separating counting character wheel box and the optical-electric module that are divided into inner chamber and exocoel; Full of liquid in the exocoel sealing of character wheel box and the chamber, and in exocoel, be provided with character wheel and corresponding four or eight gear wheels that conspire to create by print wheel shaft; The inner chamber of character wheel box is provided with the scale dish; The inner chamber of said character wheel box also is formed with one in order to the side chamber of optical-electric module to be set; The vallecular cavity part that the side chamber has straight cavity segment and forms at interval with each character wheel in the exocoel; Optical-electric module is arranged at after the side chamber, and its wiring board is in straight cavity segment, and photoelectric sensor plate then correspondence is embedded in the vallecular cavity part; The signal wire of optical-electric module directly leads to outside the box from the inner chamber of character wheel box.
Said in the formed any side that is positioned at the both sides parallel in order to the side chamber that optical-electric module is set of character wheel box inner chamber with print wheel shaft.
The invention has the beneficial effects as follows: its optical-electric module of this liquid sealing photoelectric direct-reading water meter is in the inner chamber that breaks away from liquid environment fully of fluid-tight character wheel box, thereby has obtained the seal protection of essence, the generation of thoroughly having stopped to touch the water phenomenon.Optical-electric module must not used the glue embedding, has guaranteed the reliability and the measurability of optical-electric module performance, has thoroughly solved existing structure and must adopt fluid sealant optical-electric module to be carried out the deficiency of solid envelope.Therefore simultaneously, than existing structure, scheme of the present invention also greatly reduces its difficulty on processing technology, can enhance productivity and the qualification rate of product, and reduce production costs.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the structural representation of the fluid-tight character wheel box of liquid sealing photoelectric direct-reading water meter of the present invention.
Among the figure: 1. character wheel box 11. inner chambers 111. side chambeies 12. exocoels, 21. print wheel shafts, 22. character wheels, 3. 48 gear wheels 4. optical-electric modules
Embodiment
A kind of liquid sealing photoelectric direct-reading water meter; As shown in Figure 1; It has cavity-separating counting character wheel box 1 and the optical-electric module 4 that is divided into inner chamber 11 and exocoel 12, the character wheel 22 that conspired to create by print wheel shaft 21 and the bearing pin of corresponding four or eight gear wheels, 3, four eight gear wheels 3 is set in the exocoel 12 of character wheel box 1 does not stretch out character wheel box 1; 21 of print wheel shafts stretch out character wheel box 1 from areole, and print wheel shaft 21 adopts the sealing of O type circle with the gap of areole; Exocoel 12 is through carrying out gluing connect or ultrasonic soldering realizes sealing with cover plate, and in the chamber full of liquid; The inner chamber 11 of character wheel box 1 is provided with the scale dish, and through O type circle and transparent watch glass are set, realizes the sealing of inner chamber 11 again through ultrasonic soldering; The inner chamber 11 of character wheel box 1 also is formed with one in order to the side chamber 111 of optical-electric module 4 to be set; The vallecular cavity part that side chamber 111 has straight cavity segment and forms at interval with each character wheel 22 in the exocoel 12; Optical-electric module 4 is arranged at after the side chamber 111; Its wiring board is in straight cavity segment, and photoelectric sensor plate then correspondence is embedded in the vallecular cavity part; The signal wire of optical-electric module 4 directly leads to outside the box from the inner chamber 11 of character wheel box 1.
