Abstract

The utility model relates to an electronic display water meter capable of remotely indicating, belonging to a metering product. The inner part of a meter core of a dry cold water meter is provided with a contact sensor or a light control sensor whose installing position is corresponding to the zero mark on a multiple 0.01 dial plate which is arranged at the plate surface of the meter core. The sensor is connected with an electronic display through a conducting wire. The electronic display is composed of connection of the power, a counting circuit, a liquid crystal display piece, a reset key, and a rising space key according to the principle of the electricity. The dry cold water meter and the electronic display are respectively arranged at the indoor and the outdoor to count, and therefore, the work efficiency for tax collectors for the water rate is enhanced. The electronic display can meter out the actual water consumption, and therefore, users can not steal the water. The utility model is widely suitable for metering management systems for the tap water in towns and countries.

Description

Electronics shows remote transmitting water meter

Electronics shows that remote transmitting water meter belongs to measuring products.

It is indoor that the present dry cold water meter that generally uses all is installed in the user, demonstrates the water consumption of accumulative total by mechanical counter.The staff who the imposes water rate meter reading of must registering one's residence is chargeed, and owner's work of staying out can not be carried out, and owner is in also will wait and opens the door.Not only inconvenience but also lose time.The user who has causes the wasting of resources for stolen water makes the water meter reversal connection mechanical counter reversing privately.

The objective of the invention is: a kind of user's of avoiding stolen water is provided, and shows remote transmitting water meter at the outdoor novel electron of getting the actual used water amount of just accurately looking into.

Technical scheme is: on the counting guide wheel that dry cold water meter watch core card * 0.01 index dial indicator axle lower end connects contact sensor or light-operated sensor are installed.Its installation site is corresponding with " O " some scale of * 0.01 index dial.Sensor is connected with electronic console by lead, and electronic console is by power supply, counting circuit, and LCD plate, the strong jump key that resets connects and composes by electric principle.It is indoor during use the dry cold water meter to be contained in the user, and the installation of electronic console can be arranged the user of a building or a unit building in order by doorplate according to managerial demand and be installed concentratedly, but also each household separately in outdoor mounted.When indoor mechanical water meter * 0.01 index dial lights indicator from O and turns around, word of mechanical counter meter, the sensor of installing in the watch core is a measuring point with the O point equally, the counting guide wheel that indicator axle lower end connects also rotate a circle when getting back to the corresponding position of " O " some the sensor action once produce ... individual pulse signal, input to the electronic console counting once, carry out synchronously with the mechanical counter on the water meter, the also mutually same word of measurement unit is 100Kg.

The utility model is installed in two places, indoor and outdoor counting respectively with dry cold water meter and electronic console; Improve water rate and imposed personnel's work efficiency; Electronic console measures actual water consumption and has controlled the stolen water phenomenon.Being widely used in town and country tap water metering management system uses.

Fig. 1: contact sensor construction assembling synoptic diagram.

Fig. 2: light-operated sensor construction assembling synoptic diagram.

Embodiment one carries out in conjunction with Fig. 1: the dry cold water meter is implemented by prior art fully.The contact sensor of installing in the watch core constitutes by between the projection 8 and the contact up and down 4,6 that has contact 3,5 up and down that are fixed on the counting guide wheel 9 insulator 7 being housed.The installation site of projection peak and contact will with watch core card 1 on * " O " of 0.01 index dial 2 o'clock on a perpendicular line.Projection is bonded on the counting guide wheel by metal or nonmetal manufacturing.Contact uses the platinum riveting on the contact up and down that elastic copper sheet is made up and down, bonding insulators in the middle of two contacts, and the collets that connected by following contact are fixed on the watch core base plate.。Two contact gaps, 0.2～0.3mm.When projection 8 peaks of counting on the guide wheel 9 forward to * upper and lower contact is connected during the correspondence position of 0.01 index dial 2 " O ", sensor output signal inputs to the counting circuit of electronic console 11 by lead, by LCD plate 10 numeral is shown.Working power 12 counting circuits in the electronic console, strong 13 reset keys 14 of rising space connect by electric principle.

Embodiment two carries out in conjunction with Fig. 2: the light-operated sensor of installing in the watch core is by light-emitting component 15 and be fixed on block 16 and light activated element 17 and the light-operated circuit of counting on the guide wheel 9, and relay connects and composes by electric principle.Block selects lighttight material to make, and the position that is fixed on the counting guide wheel is corresponding with * 0.01 index dial " O " point.Its central point is wanted and light-emitting component, and the central shaft of light activated element point-blank.Light-emitting component can be selected far infrared power valve or miniature bulb for use, light activated element can select for use far infrared receiving tube or photodiode to be separately fixed on the watch core base plate of counting guide wheel both sides, by lead respectively with the working power and the light-operated circuit that are installed in the electronic console, relay links to each other.Identical and the embodiment one of the enforcement of dry cold water meter and electronic console.Block rotates in company with the counting guide wheel, leave * light-emitting component shines directly on the light activated element during " O " some position on 0.01 index dial, and light-operated circuit is in closed condition, does not have electric current to pass through, the relay clutch, electronic console is not counted.The light of light-emitting component is blocked by link stopper when getting back to the corresponding position of index dial " O " point when baffle plate circles, the light activated element conducting, and light-operated circuit has electric current, numeral of a relay adhesive pulse signal electronic console meter of output.

No matter the mechanical counter in the indoor dry cold water meter of electronics demonstration remote transmitting water meter just changes or reverses, as long as water, electronic console just can accumulative total strictly according to the facts go out water consumption.But controlled the disadvantage of stolen water.
