Abstract
The utility model relates to a water meter with IC card payment, which comprises an IC card, a secondary meter, a power source and a water meter, wherein an information conversion mechanism and a water quantity control mechanism are arranged in the water meter, the information conversion mechanism is composed of a clutch, a miniature motor and a driving wheel installed on a motor mainshaft, and the water quantity control mechanism is composed of a threaded rod or a screw mandrel and a stop block; one end of the threaded rod or one end of the screw mandrel is connected with a counter shaft or a sequent driving shaft thereof, and the other end is connected with the stop block to extend to the neck part of a water outlet pipe of the water meter. Electricity needs consuming only when the card is inserted to input the information of water quantity, a mechanical mechanism is used for realizing control to the water consumption of the metering and the display of the water quantity, the power source may not be arranged on the water meter, and the utility model has the advantages of simple structure, small volume, safe use and reliable performance.
Description
The utility model relates to a kind of water metering charging device, particularly a kind of IC-card prepay water meter.
Traditional water meter 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, the rotary wind type blade, gear drive, many grades of display discs, counter, also have by the IC-card seat, microprocessor, storer, the control circuit that motor-drive circuit 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 power wheel on the electric machine main shaft is formed, clutch device is on the electric machine main shaft or on the follow-up transmission shaft at motor, and power wheel is through that one-level gear transmission backward of Clutch Control; Also have by screw rod or screw mandrel, by the water yield control gear that piece is formed, screw rod or screw mandrel one end link to each other with counter axle or its follow-up transmission shaft, the other end by end screw thread in the piece or screw with it interlock extend to the neck of the rising pipe of water meter.
Be described this use is novel with reference to the accompanying drawings and in conjunction with the embodiments.
Figure one is the utility model principle of work block diagram.
Figure two is the utility model outward appearance vertical view.
Figure three is the schematic diagram of the utility model water meter.
Shown in figure one, the composition of the utility model IC-card prepay water meter comprises IC-card, secondary instrument, power supply and water meter.
Shown in figure two, has rising pipe 1 in the utility model water meter case, many grades of counters 2, rotary wind type blade pointer 3, many grades of display discs 4, water inlet pipe 5, electric control box 6.
Shown in figure three, have by clutch coupling 12, clutch arm 13, micromotor 15 in the water meter, be contained in the information translation mechanism that the gear 16 of input worm screw 11 on motor 15 main shafts 14, input worm gear 10 and water meter x0.1 position level is formed, clutch coupling 12 is contained on the main shaft 14 of motor 15, link to each other with clutch arm 13 1 ends simultaneously, the lower end of the other end of clutch arm 13 and gear 16 is hinged; Also has the water yield demonstration control gear of forming by counter 1,2,3,4, counter main shaft 5, screw rod 6, by piece 7, water delivering orifice 8, counter 1,2,3,4 be respectively the water yield show, ten, hundred, kilobit, counter main shaft 5 is fixing with counter 1, counter 2,3,4 skies are enclosed within on the counter main shaft 5, screw mandrel 6 fixedly is connected on the counter main shaft 5, utilizes the screw thread at center to link to each other with screw rod 6 by piece 7 and stretches to rising pipe 8.
The course of work of the present utility model is as follows:
1, input water yield information: when micromotor 15 runnings, its transmission input worm screw 11 and clutch coupling 12 runnings, clutch coupling 12 drives clutch arm 13 moves upward gear 16, make gear 16 and gear 17 throw off and and the coaxial gear 10-1 engagement of worm gear 10, the running of micromotor 15 is delivered to counter through worm screw 11, worm gear 10, gear 16, worm screw 9 and shows corresponding surplus water like this, the rotation of counter 1 makes screw rod 6 rotation, simultaneously by ball 7 corresponding works left rectilinear motion widen distance between piece 7 and rising pipe 8.
2, show and control with water surplus: after motor 15 shuts down, the power that makes progress of 13 pairs of gears 16 of clutch arm has stopped, gear 16 is thrown off with input worm gear 10 coaxial gear 10-1 under the action of gravity of self, and mesh with gear 17, rotary wind type blade 20 driven gear groups 19, gear 18,17,16, worm screw 9, counter 1,2,3,4, screw rod 6 motions end ball 7 moving linearly to the right thereby drive during water.Reduce gradually along with surplus water and shorten by the distance of ball 7 and rising pipe,, remind the user in time to import water yield information when necessarily having influence on the aquifer yield that makes water in short-term.Also do not import water yield information when the water yield uses up, water inlet pipe 8 will be cut off ball 7 and block, thereby closes the use of water.
The utility model has the advantage of to take full advantage of traditional flowmeter, designed water yield telecommunications Breath is converted to the mechanical mechanism of mechanical information, realizes metering, demonstration, the water of the water yield with this mechanical mechanism Control. Only when plug-in card input water yield information, need power consumption, thus water meter charged not, structure Simply, volume is little, uses safety, dependable performance, and cost is low, for concentrated, scientific management water rate are collected Work provides effective and feasible instrument.
