Fig. 5 is the constitutional diagram when surplus water is greater than 1 cubic metre in the utility model 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, has water inlet pipe 1 in the utility model water meter case, many grades of counters 2, rotary wind type blade pointer 4, many grades of display discs 3, rising pipe 5, electric control box 6, watchcase 7.

As shown in Figure 3, Figure 4, have by clutch coupling 20, clutch arm 19, micromotor 23 in the water meter, be contained in the information translation mechanism that the gear 26 of input bevel gear 22, input bevel gear 21 and water meter x0.1 position level on motor 23 main shafts 24 is formed, clutch coupling 20 is contained on the main shaft that passes through housing 25 24 of motor 23, link to each other with clutch arm 19 1 ends simultaneously, the other end of clutch arm 19 is corresponding with the lower end of gear 26; Also have by

counter

2,3,4,5, counter main shaft 7,

output gear

6,8, output shaft 15, water delivering orifice 9, cam is to 13,14, back-moving spring 12, fixed block 10, the water yield that cam guide pillar 11 is formed shows control gear,

counter

2,3,4,5 is respectively the individual of water yield demonstration, ten, hundred, kilobit, counter main shaft 7 is fixing with counter 5,

counter

2,3,4 skies are enclosed within on the counter main shaft 7, output gear 6 is fixed on the counter main shaft 7, output gear 8 and cam 14 are fixed on the two ends of output shaft 15, fixed block 10 is fixed in the water delivering orifice, the cam guide pillar is fixed on the fixed block 10, back-moving spring 12 and cam 13 skies are enclosed within on the cam guide pillar 11, back-moving spring 12 is pressed on the cam 14 cam 13, and axially-movable is only done in the motion between cam 13 and the cam guide pillar.

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

Input water yield information: during micromotor 23 runnings, its transmission input bevel gear 22 and clutch coupling 20 turn round clockwise, the position that clutch coupling 20 drive clutch arms 19 are pushed down gear 26-5 moves upward, make the conical gear at the conical gear at gear 26-4 position and gear 18-1 position throw off and make the conical gear and the engagement of input bevel gear 21-2 position at gear 26-2 position, simultaneously the spur gear at gear 26-3 position all the time with the spur gear engagement at worm screw 1-2 position, the running of micromotor 23 is through input bevel gear 22 like this, 21, gear 26, worm screw 1 is delivered to counter and reverses, the reverse of counter 2 makes
