Abstract
The utility model relates to a novel water meter with an intelligent card, which is composed of batteries, a magnetic steel arranged on a gear with 10L number of bits, a metering instrument with a sensor on the upper part, a controller, a display screen, a miniature motor and a valve. The utility model is characterized in that a speed reducer is additionally arranged; the valve uses an electric valve which is driven by the miniature motor through the speed reducer. The metering instrument, the magnetic steel, the sensor, the controller, the speed reducer, the miniature motor and the electric valve are sealed in an iron box. The utility model has the advantages that the electric valve can be freely opened and closed no matter in high water pressure or low water pressure regions; thus, the range of application of the water meter is enlarged; the malfunction because of hole block of the electric valve does not exist; in addition, the components of the water meter have magnetic shield; thus, the reliability and the service life of the water meter with an intelligent card are enhanced.
Description
The utility model relates to a kind of tap water enterprise or administration departments of being used for to the charge a kind of novel smart card water meter of metering of user, claims the IC-card water meter again.
Water meter was the mechanical type water meter in the past; no intelligent functions; pay after the user elder generation water; it is indoor that water meter generally is installed in the resident, and Running-water Company or administration departments needed dispatch officers to check meter to the doorstep in every month, time-consuming effort again; and run in the user family unmanned and can't check meter through regular meeting; cause check meter difficulty and difficult charge, and concerning the user, checking meter to the doorstep to make them produce unpeaceful sense.After smart card water meter is arranged, its principle is when current time impulsion wing wheel rotation through water meter, thereby driving the upper gear group rotates, when the gear that magnet steel is housed rotates, inhale dynamic sensor, then send signal to intelligent integrated circuit controller, the i.e. water yield of successively decreasing automatically and presetting, begin to report to the police when reaching certain water yield, after the forward purchasing water yield used up, valve was closed voluntarily.Yet existing at present smart card water meter all adopts solenoid valve, and its shortcoming is:
1, the solenoid valve pressure loss is big, and the pressure loss of solenoid valve adds the pressure loss sum of measuring instrument, substantially exceeds the regulation of water meter national standard, causes user's water not smooth, and the user in low hydraulic pressure area might can't use shower.
2, the electromagnetic valve guide pore volume easily stops up.The aperture in electromagnetic valve guide hole generally only about 2mm, is stopped up by impurity in the water or incrustation scale easily, causes solenoid valve to move, and smart card water meter can not be worked.
3, hydraulic pressure is low excessively, most solenoid valves can't start, the highest one, the two layer user of the user in low hydraulic pressure area or the tier building of roof tank, because hydraulic pressure is low excessively, the pressure reduction that acts on rubber membrane two ends in the valve is also very little, can not overcome spring pressure, and valve can't be moved, cause the smart card water meter can not water flowing, the user just uses less than water.
In addition, the measuring instrument of existing smart card water meter, controller, solenoid valve etc. disperse to install, and do not have antimagnetic function, disturb in case run into extraneous high-intensity magnetic field, and smart card water meter is with regard to malfunctioning or serious misalignment.
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of accurate measurement, reliable operation, applied widely to be provided, and becomes water behind the post-pay paystation, reaches the smart card water meter that automatic charging and pre-payment limit supply water.
The technical solution of the utility model is: it is by on battery, the 10L figure place gear magnet steel being housed and top is made up of measuring instrument, controller, display screen, micromachine and the valve of sensor, be characterized in that valve adopts motorized valve, drives motorized valve by micromachine by reduction gear; Measuring instrument, magnet steel, sensor, controller, reduction gear, micromachine, motorized valve are sealed in the can made from the sheet iron material.
The utility model embodiment is further described in conjunction with the accompanying drawings.
Fig. 1 is the smart card water meter structural front view,
Fig. 2 is the A-A view of Fig. 1;
Fig. 3 is the reducing gear structural representation;
Fig. 4 is a reducing gear gear stretch-out view.
Shown in Fig. 1,2, smart card water meter is made up of sensor 4, controller 8, display screen 7, micromachine 10, reduction gear 11 and cover plate 9 thereof, ball valve 12 and the measuring instrument 20 on magnet steel 18 that is equipped with on lithium battery 19, wing wheel 2, the 10L figure place gear and top thereof, reduction gear 11 is for being contained in the gear set that gear 13 on the micromachine 10 and gear 14,15,16, sector gear 17 are formed, and sector gear 17 is fixed on the mandrel of ball valve 12.Therefore, when micromachine 10 receives the action command of controller 8, by 13 driven gears 14,15,16 of the gear on the micromachine 10 and sector gear 17 rotations, be fixed on because of sector gear 17 on the mandrel of ball valve 12, so the mandrel of ball valve 12 and sector gear 17 rotate synchronously, the purpose that reaches out, opens.When installing for ease of water meter and external pipe join, the external pipeline section of ball valve adopts the G3/4 external thread.
Disturb for reaching anti-external magnetic field, measuring instrument 20, magnet steel 18, sensor 4, controller 8, reduction gear 11, micromachine 10, ball valve 12 are sealed in the can made from the sheet iron material, the sheet iron material trademark is 08F, and can is made up of lower house 1, middle shell 3, central dividing plate 5 and upper shell 6.
The principle of work of the utility model smart card water meter is: the power supply of water meter is to be supplied with by lithium battery 19, when current are flowed through water meter, 2 rotations of impulsion wing wheel, the gear set that wing wheel 2 drives measuring instrument rotates, and wherein on the 10L figure place gear magnet steel 18 is housed, when this gear rotates, magnet steel 18 is inhaled dynamic sensor 4, make it send 1 signal and transfer to controller 8, the water yield of successively decreasing automatically and presetting is when surplus water arrives 3m
3The time, the water meter hummer begins to report to the police, when surplus water arrives 2m
3, 1m
3And 0m
3The time, each is reported to the police 1 time, at 0m
3The time, paying symbol " $ " appears on display screen, and simultaneously, controller is given an order, and makes micromachine 10 drive reduction gear 11 and ball valve 12 turn over certain angle, flow is obviously turned down, later every consumption 0.1m
3Water is reported to the police 1 time, until showing that surplus water is-1m
3The time, controller is given an order once more, and micromachine is rotated until with the ball valve Close All.
The utility model is to be driven by the reduction gear set up by micromachine to can be ball valve or butterfly valve, gate valve replacing solenoid valve commonly used, thereby makes valve in the 0-1Mpa range hydraulic pressure, opens and closes freely, improves the scope of application of smart card water meter.In addition, the motorized valve pressure loss is little, makes the pressure loss of smart card water meter reach the requirement of water meter national standard, makes user's water unimpeded.Because motorized valve does not have pilot hole, so there is not the malfunctioning problem of plug-hole, can improve the reliability and the serviceable life of water meter.The utility model also is sealed in all components and parts except that display screen among the iron-clad of 08F, and external magnetic field is played shielding action, thereby improves water meter measurement accuracy, operational reliability and serviceable life.
