Description

A kind of IC-card prepay water meter

The utility model relates to a kind of water metering charging device, particularly a kind of IC-card prepay water meter.

Traditional water rate management is to check meter earlier, the back charge.Make the mode of water behind the at present more novel IC-card prepay water meter employing post-pay paystation.But existing IC-card water meter utilizes complicated solenoid valve to control the break-make in water route mostly, must possess power supply in the water meter, just can make the water meter operate as normal, and all must consumed power in the entire work process.This water meter structure complexity, the cost height uses inconvenient.

The purpose of this utility model is, overcomes the weak point of above-mentioned IC-card water meter, not consumed power, simple in structure, IC-card prepay water meter that cost is low, easy to use when a kind of operate as normal is provided.

The purpose of this utility model is achieved through the following technical solutions: a kind of IC-card prepay water meter, its composition comprises IC-card, secondary instrument, power supply and water meter, water meter has housing, turbine, gear drive, many grades of display discs, turbine indication blade, also have by the IC-card socket, microprocessor, memory, the control circuit that driver is formed, it is characterized in that having in the water meter by clutch coupling, micromotor, be contained in the information translation mechanism that the transmission gear on the electric machine main shaft is formed, on the clutch device one-level transmission shaft in office, it is big to be positioned at this level, between the pinion wheel, the gear of transmission gear and clutch coupling subordinate gear train oppositely meshes; Also have by tooth bar, pointer, scale, connecting rod, end the water yield demonstration control gear that ball is formed, the gearing mesh of tooth bar and clutch coupling subordinate gear train, pointer is fixed on the tooth bar, scale is contained on the display disc and the pointer corresponding position, connecting rod one end connects tooth bar, and the neck that the other end shrinks by the housing water inlet pipe is connected with the ball that ends in the water inlet pipe.

With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.

Fig. 1 is the utility model principle of work block diagram.

Fig. 2 is the profile vertical view of the utility model water meter.

Fig. 3 is the A-A cut-away view of Fig. 2.

Fig. 4 shows the control gear synoptic diagram for the utility model water yield.

Fig. 5 is the control circuit schematic diagram in the water meter.

As shown in Figure 1, the composition of the utility model IC-card prepay water meter comprises IC-card, secondary instrument, power supply and water meter.

As shown in Figure 2, have many grades of display discs 3 in the utility model water meter case 1, turbine (meaning not shown in the figures), turbine indication blade 7, the water yield shows the pointer 2 and the scale 4 of control gear, water inlet pipe 6 and the neck 5 that shrinks thereof, rising pipe 8.

As shown in Figure 3 and Figure 4, have by clutch coupling 11, micromotor 13 in the water meter, be contained in the information translation mechanism that the transmission gear 12 on the electric machine main shaft 14 is formed, clutch coupling 11 is contained on the position level transmission shaft 15, between the large and

small gear

17,16 of this grade, transmission gear 12 oppositely meshes with the neutral gear 20 of clutch coupling following stages (for example ten levels) gear train; Also has the water yield demonstration control gear of forming by tooth bar 21, pointer 2, scale (among Fig. 2 4), connecting rod 22, by ball 23, tooth bar 21 meshes with the gear 19 of clutch coupling 11 following stages gear trains, pointer 2 is fixed on the tooth bar 21, scale 4 is contained in display disc (among Fig. 2 3) and goes up and pointer 2 corresponding positions, connecting rod 22 1 ends connect tooth bar 21, and the neck 5 that the other end shrinks by the housing water inlet pipe is connected with the ball 23 that ends in the water inlet pipe 6.

As shown in Figure 5, also has the control circuit of forming by IC-card socket CN1, microprocessor IC1, memory IC2, driver IC 3 in the water meter.This circuit only need provide power supply to carry out work when inserted IC card, reads water yield information in the IC-card by IC1, drives micromachines 13 work by driver IC 3, carries out water yield information translation, and conversion work finishes, and just no longer needs power supply.Therefore consumed power not during the utility model water meter operate as normal.

The course of work of the present utility model is as follows:

1, input water yield information: when micromotor 13 runnings, its transmission gear 12 drives neutral gear 20 antiports of clutch coupling following stages (ten levels) gear train, and then the following stages and tooth bar 21 counter motions of drive neutral gear 20, the pointer 2 on the tooth bar 21 is indicated surplus water at that time on scale 4.This moment, clutch coupling 11 was thrown off the big pinion wheel on the transmission shaft 15 17,16, gear 17 antiports, and gear 16 and preceding continuous level (ten/one-level is following) thereof and turbine all shut down.

2, show and control with water surplus: after motor 13 shut down, original gear drive ran well when water, moved thereby drive tooth bar 21 forwards, and the surplus on the scale 4 is reduced, and moved to water inlet pipe neck 5 by ball 23 simultaneously; When surplus hour, press close to the water inlet pipe neck by ball 23, aquifer yield is diminished gradually, remind the user in time to import water yield information.

Advantage of the present utility model is to make full use of traditional flowmeter, designed the mechanical mechanism that water yield electrical information is converted to mechanical information, realizes metering, the demonstration of the water yield, the control of water with this mechanical mechanism.Only need power consumption when plug-in card input water yield electrical information, so water meter can not charged source, simple in structure, volume is little, and is safe in utilization, dependable performance, cost is low, for concentrate, unified, the scientific management water rate work of collecting provides effective and feasible instrument.

For the use of the control charge water yield more effectively, the further feature of the utility model is, as shown in Figure 3 and Figure 4, (1), forms by concentric inside and outside two

ball

23B, 23A by ball, the interior ball 23B that ends is fixed on connecting rod 22 1 ends, and be arranged in outer radial direction through hole 231, interior aperture of ending the diameter of ball 23B greater than radial direction through hole 231 ends by ball 23A.When water surplus diminishes gradually, along with the forward of tooth bar 21 moves, block water inlet pipe neck 5 by outer by ball 23A earlier, can only have this moment the water of minute quantity to pass through, give the user with clear and definite caution by the slit between radial direction through hole 231 and interior ball 23B of ending and the connecting rod 22; (2), tooth bar by main tooth bar 21A and with it in the same way secondary tooth bar 21B form, the distance of the meshing point of main tooth bar 21A to the front end of the distance of its end and secondary tooth bar 21B to another transmission gear 20 meshing points equate, and work has correspondingly sign on scale (shown among Fig. 2 4) simultaneously.Can carry out following setting: when only certain surplus being arranged, main tooth bar 21A moves to end, secondary tooth bar 21B and gear 20 engagements, driving secondary tooth bar 21B continuation forward by gear 20 moves, can obtain high-resolution reading this moment on scale, simultaneously, guarantee by ball not influence normal water supply before certain surplus and between the water inlet pipe neck 5 certain distance is arranged.
