Present automatic remote reading technique has occurred a kind of by installing the photoelectric sensor assembly additional, reads the device of a measuring instrument reading information, and promptly the photoelectric direct-reading sensor device is called for short opto-electrical direct reader.This device is done technological transformation by the counter character wheel to former mechanical count apparatus, adopt the photoelectric sensor parts, registration on the counter character wheel is converted into digitally encoded signal, pass through communication interface, directly reading is outputed to the far-end kilowatt meter recorder, this direct readout does not need power supply at ordinary times, has only just moment power supply in the time of to check meter, solved with in the prepulse kilowatt meter reading-out system long-term powerup issue, because the photoelectric sensor circuit need insert between the counter character wheel of gauge table, for ammeter, the realization ratio of leaving water environment such as gas meter, flow meter is easier to, but for water meter, especially wet-type meter is realized relatively difficulty, need solve the waterproof installation question of photoelectric sensor wiring board and other electronic circuit components for wet-type meter, processing mode for wet-type meter is at present: make a plastic cement chamber below water meter counter character wheel box, the photoelectric sensor wiring board inserts between the counter character wheel from the bottom up, the electronic circuit part is contained in the cavity by sealant sealing, isolate with water, though this processing mode can solve the waterproof installation question of circuit pack, but it is following, brought new problem, because the electronic circuit part must be sealed in the cavity, and be made as one with the mechanical part of water meter, as being made as one and non-dismountable with counter character wheel box, cause the fault of any one part all integral body to be scrapped, make the electronic circuit part not have maintainability, the cost height, cost is big, assembling is complicated simultaneously, to increase use cost, with cost of manufacture, seriously restricted the popularization of passive light photoelectric direct reading wet-type meter.
Summary of the invention:
Purpose of design of the present invention: a kind of photoelectric direct reading machine for wet type vane wheel water meter is provided, the opto-electrical direct reader that is provided does not have any contact with the mechanical transmission component of wet-type meter, when opto-electrical direct reader assembles, electronic circuit component is as an independently parts assembling, can freely dismantle, simultaneously when water meter assembles, the photoelectric direct reading machine for wet type vane wheel water meter that is provided is as an individual components, be assemblied in the water meter, solved the problem of wiring board water-proofing treatment, can directly be installed in the wet-type meter, by the photoelectric direct reading machine for wet type vane wheel water meter that is provided is provided, only need the structure of water meter is done very little modification, the simple realization transform common water meter as passive light photoelectric direct reading wet-type meter.
The present invention is achieved through the following technical solutions: wet-type meter direct read device of the present invention comprises: the photoelectric sensor wiring board, the signal processing circuit plate, electrical signal lead, counter character wheel box, the counter character wheel, counter character wheel box bottom plate, it is characterized in that: the counter character wheel is coaxially installed in the counter character wheel box, in the position that counter character wheel box is used to install the counter character wheel, by making coherent tongue and groove counter character wheel box is divided into two untight cavitys that do not connect up and down, lower cavity is used to install counter character wheel and counter character wheel drive disk assembly, the counter character wheel inserts in the groove of seeing from the bottom up, after assembling is finished, seal with counter character wheel box bottom plate, lower cavity perfusion clear solution is to guarantee the pressure equilibrium in the cavity and to keep the clean of counter character wheel; The photoelectric sensor wiring board is installed on the signal processing circuit plate, the signal processing circuit plate is fixed in the upper chamber of counter character wheel box, the photoelectric sensor wiring board inserts in the groove of seeing from top to bottom, by adopting the method for fluting from top to bottom, and the method that the electronic circuit part is installed from top to bottom, promptly adopt the dry type installation method of wet-type meter electronic circuit board, solve the waterproof installation question of electronic circuit board, make the electronic circuit part break away from the environment that contacts with water in the water meter fully, the electronic circuit plate portion is no longer realized waterproof by the sealed colloid embedding simultaneously, make electronic circuit board possess maintainability, simple installation, electric signal is drawn lead and is directly drawn water meter table body from the water meter top in addition, has solved the problem that water meter signal wire waterproof is drawn.
First technology innovation of the present invention is: adopt the method for opening the wiring board installation cavity from counter character wheel box from top to bottom, make the simple installation of electronic circuit, solve the problem of waterproof sealing simultaneously.
Second technology innovation of the present invention is: signal processing circuit plate, photoelectric sensor wiring board are directly installed from the end face of water meter counter device character wheel box, make wet-type meter photo-electronic directly reading electronic circuit part, as one independently parts be installed in the passive light photoelectric direct reading wet-type meter, can dismantle separately, change.
The 3rd technology innovation of the present invention is: electric signal is drawn lead and is directly drawn water meter table body from the water meter top in addition, has solved the problem of water meter signal wire output.
By above-mentioned technology implementation scheme as seen, of the present invention being skillfully constructed, novel structure can directly utilize the movement and the shell of existing common fluid-tight wet-type meter, transform common fluid-tight wet-type meter as number and passes wet type photo-electronic directly reading water meters, existing part change is few, therefore, promptly reduce production cost, also lowered the difficulty of following process simultaneously, so this photoelectric direct reading machine for wet type vane wheel water meter helps promoting, using.
