Description

A kind of anti-leakage intelligent watermeter

The invention belongs to tap water anti-leakage intelligent watermeter technical field.

The water supply pattern of Running-water Company generally is to arrive little water meter again by big water meter at present.Big water meter is mounted in a unit or the collective unit of community more, and little water meter then is directly installed in the citizen user family.Can not count when at present the flow of the little water meter in commercially available prod is less than certain value (as 12 liters/hour), can not count as long as the little water meter like this in the user family is no more than the then little water meter of this discharge.If though how tame user does not count on the little water meter of every family with this low discharge simultaneously, but it is exactly big flow that table shows on big water meter, thereby on big water meter, demonstrate certain numerical value, the shown numerical value summation of the big water meter of generalized case is Duoed more than 10～30% than little water meter demonstration numerical value accumulated value, causes the difference of big or small water meter counting like this.Owing to exist this difference often to cause some unnecessary economic conflict and disputes.

Purpose of the present invention will solve the key problem in technology problem that little water meter water clock is not counted exactly.

Technical scheme of the present invention is achieved in that in conjunction with the accompanying drawings.Fig. 1 has the product structure front elevation of valve and sender water meter for the present invention, and Fig. 2 does not have the product structure front elevation of valve and sender water meter for the present invention, and Fig. 3 is a sleeve perspective view of the present invention, and Fig. 4 is an electric theory structure synoptic diagram of the present invention.A kind of anti-leakage intelligent watermeter by the Single-chip Controlling processing, it is characterized in that, as shown in Figure 1, by seal pad 4, big water delivering orifice 5, signal hop 6, pressure spring 7, drive link 8, piston 9, water clock water hole 10, upper press cover 13, O-ring seal 14, shell 15, sleeve 16 grades are partly formed anti-leakage water meter, arrow among Fig. 1 is a water (flow) direction, the anti-leakage water meter left end is connected to valve, valve is divided into head portion 2 and valve body part 3, on the left side of head portion 2 is water inlet 1, head portion 2 and valve body part 3 can be by multiple versions, as solenoid valve, motor valve motorized valves etc., the valve of above-mentioned multiple version is known technology and repeats no more.Right-hand member at anti-leakage water meter is connected to sender water meter 11, and sender water meter 11 is a known technology, repeat no more, and be water delivering orifice 12 at the right-hand member of sender water meter 11.A kind of anti-leakage intelligent watermeter, it is characterized in that, as shown in Figure 2, upper press cover 17 be fixed on housing 18 above, sleeve 21 is fixed on the inside of housing 18, big water delivering orifice 19 is in the first half of sleeve 18,20 is water inlet, piston 22 is fixed on the lower end of drive link 23, drive link 23 is contained in the inside of sleeve 21, and pressure spring 24 is enclosed within on the drive link 23, and the latter half at sleeve 21 is left in water clock water hole 25,26 is water delivering orifice, O-ring seal 27 is in the upper end of drive link 23, seal pad 28 be fixed on upper press cover 17 above, on seal pad 28, be connected to signal hop 29, signal hop 29 can adopt multiple transmission mode, as pressure transducer, potentiometer, tongue tube, photoelectric tube, Hall element etc.A kind of anti-leakage intelligent watermeter is characterized in that, sees Fig. 3, big water delivering orifice 30 is opened the first half at sleeve 31, and it has a plurality of big water delivering orifices, and shape can be rectangular mouthful or oval mouthful, the latter half at sleeve 31 is left in water clock water hole 32, and it has a plurality of circular apertures.A kind of anti-leakage intelligent watermeter is characterized in that, as shown in Figure 4, and single-chip microcomputer U ₁With signal processor U ₈Link to each other, and and signal amplifier U ₉Link to each other signal amplifier U ₉With sender water meter 11 (Fig. 1) U ₆Link to each other single-chip microcomputer U ₁Pass through resistance R ₉With signal hop 6 (see figure 1) U ₇Link to each other single-chip microcomputer U ₁With storer U ₃Link to each other, and and LCD U ₂Link to each other power supply U ₅For each several part provides operating voltage.The principle of work of the present invention and the course of work, when water when water inlet 1 flows into, effect by valve body part 3 makes head portion 2 open valve, current enter in the anti-leakage water meter along arrow direction among Fig. 1, promote to move on the piston 9 by the pressure that current produced, at this moment the antidrip water hole of sleeve 16 has current to flow out, though there is less discharge to flow, also can make on the piston 9 and move, drive link 8 also with on move, the last Mobile Communication of drive link 8 crosses signal hop 6 water flow signal is become electric signal, this signal conveys to single-chip microcomputer U ₁In, by single-chip microcomputer U ₁Processing and control, make it demonstrate discharge.The antidrip water hole of exposing when current are big is many more, and shown discharge data are big more.When discharge is big more, to move greatly more on the piston 9, when big water delivering orifice 5 was exposed, at this moment signal hop 6 no longer worked discharge, passes through water delivering orifice 12 by sender water meter 11, spreads out of water flow signal, delivers to single-chip microcomputer U greatly ₁Make it show discharge by processing and control.

Outstanding feature of the present invention, when discharge less than 12 liters/time, promptly during the water swivel water clock, still count enable metering of anti-leakage intelligent watermeter, can prevent that like this current that caused because of the water swivel water clock from losing, also can reduce the difference metering between the big or small water meter, guarantee that citizen user hands over the rationality of water rate.The present invention has by water clock and count down to the function that big yield counting can be changed voluntarily, and have automatic control, automatically counting, show functions such as storage.It also has highly sensitive, advantages such as reliability is high, good reproducibility, Installation and Debugging convenience, and is easy to utilize.It can be widely used in tap water supply system, for Running-water Company directly to citizen user's water condition of providing convenience.

Embodiment:, after the hardware of water clock intellectual water meter completed, weld according to the requirement of Fig. 4 again according to the requirement of Fig. 1, Fig. 2.Single-chip microcomputer U ₁1 pin meet signal processor U ₈In R ₈, and meet storer U ₃8 pin, sender water meter 11 is by sensor U ₆3 pin, power supply U ₅2 pin, signal amplifier U ₉In U ₄: 4 pin of A and LCD U ₂2 pin link to each other single-chip microcomputer U ₁2 pin and LCD U ₂3 pin link to each other U ₁3 pin and signal amplifier U ₉In U ₄: 1 pin of A, and pass through resistance R ₁Link to each other U with 2 pin ₁4 pin and LCD U ₂1 pin link to each other.U ₁5 pin pass through R ₉With sensor U ₇2 pin link to each other U ₁6 pin and storer U ₃6 pin link to each other U ₁7 pin and storer U ₃5 pin link to each other its 8 pin and power supply U ₅1 pin link to each other and and C ₃Link to each other, and and the sensor U of signal hop 6 ₇1 pin link to each other.Signal amplifier U ₉In U ₄: 3 pin of A pass through resistance R ₀And U ₆2 pin link to each other U ₆1 pin, U ₄: 11 pin of A, U ₅1 pin, U ₂4 pin, U ₃The equal ground connection of 1,2,3,4,7 pin.After above-mentioned line connection, can reach result of use by debugging.
