Abstract
A liquid crystal digital display electronic water meter is divided into an upper part and a lower part by a sealing cover device, a filter screen, an impeller box, a gear pair and other devices are sequentially arranged in a cast iron shell of a rotary impeller type water meter at the lower part, wherein a magnetic steel is fixed on a final-stage gear of the gear pair, a reed switch is arranged above the sealing cover at the upper part of a meter body and aligned with the circumference of the rotation of the magnetic steel, and a power supply part for supplying power to the reed switch is arranged at the same time.
Description
The utility model relates to a kind of measuring apparatus of discharge, particularly relates to a kind of metering water meter that shows discharge with the liquid crystal digital display device.
At present, the measuring apparatus of discharge has various ways such as pivoting leaf is wheeled, ultrasonic type, electromagnetic type.Its display device is not to adopt pointer to show, adopts civil power exactly.When adopting the water meter of mains-supplied, the place of no civil power can not be used, and data are easily lost when civil power cuts off the power supply again, so its application is very restricted.And when the water meter that adopts pointer to show, its reading is not directly perceived, and total flow knows that just after the water inlet of mechanical water meter card was got rusty, it is unclear that metering shows simultaneously after need calculating, and has caused certain difficulty to meter reading person.So such structure is not only measured intensive reading and can not be guaranteed that the metering to low discharge is comparatively difficult simultaneously.
Because above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of electronic water meter of liquid crystal display, and this water meter adopts electromagnetic sensing mode, and mode that can liquid crystal display shows discharge intuitively.
For achieving the above object, the utility model adopts following technical scheme, that is: a kind of liquid crystal digital shows electronic water meter, be divided into two parts up and down by a seal cover assembly, in the cast iron housing of the wheeled water meter of its underpart pivoting leaf, order is equipped with devices such as filter screen, impeller box and gear pair, wherein fixes a magnet steel on the final stage gear of described gear pair; Above the described gland bonnet in top of table body, aim at the circumference place that magnet steel rotates and be provided with a tongue tube, and be provided with simultaneously and to the power unit of its power supply.
Now, will make above-mentioned purpose of the present utility model and other advantage apparent in conjunction with the accompanying drawings by description to the utility model embodiment.In the accompanying drawing:
Fig. 1 is the longitudinal sectional view that liquid crystal digital of the present utility model shows electronic water meter;
Fig. 2 is the fundamental diagram that liquid crystal digital of the present utility model shows electronic water meter.
As shown in Figure 1 be the longitudinal sectional view that liquid crystal digital of the present utility model shows electronic water meter, its external structure is similar with known water meter basically.Be separated into two parts up and down at shell 13 internal surface bodies by nonmagnetic substance tempered glass sealant 7.The bottom is provided with filter screen 12, is provided with impeller box 11 in this filter screen 12, and sampling is arranged on the bearing with impeller 10 in this impeller box 11, can rotate flexibly; The rotating shaft of this impeller 10 is provided with tertiary gear ancillary equipment 9, and is fixed with a magnet steel 8 on third level gear.This tempered glass sealant 7 installs isolating seal in shell 13 with aqueous medium, impeller 10, gear pair device 9 magnet steel 8 etc.The top of table body is by 5 sealings of gauge outfit lid, aims at the circumference place that magnet steel 8 rotates above near tempered glass sealant 7 on this gauge outfit lid 5 times and is provided with a tongue tube 6; And the top at this table body is provided with dry cell and photoelectric cell again simultaneously, and power supply is counted/latched/display drive apparatus (not shown) and LCD 4 to one respectively, as shown in Figure 2.When current process screen pack 12, enter in the impeller box 11, will promote impeller 10 and rotate, these impeller 10 driven gear ancillary equipments 9 rotate, thereby drive magnet steel 8 rotations; The 3rd gear of gear pair 9 whenever circles, magnet steel 8 is once inswept from the below of tongue tube 6, the magnetic line of force passes the sealant 7 of nonmagnetic substance, the junction closure that makes tongue tube 6 once, the every closure of the contact of this tongue tube 6 is once counted/latch/the display drive apparatus (not shown) just receives sampled signal one time.Its value of inserting that will add up on the basis of initial value has realized the accumulative total of flow, and by LCD 4, accumulated value has been shown.
Secondly, in order to reach the adjustable purpose of the intensive reading that makes water meter, can also be auxiliary with a toggle switch device (not shown) on the top of table body of the present utility model.
In sum, adopt liquid crystal digital of the present utility model to show that electronic water meter can read the numerical value of discharge intuitively.In the practice, the utility model adopts No. 5 dry cells, and photoelectric cell utilizes sun power that energy is provided, thereby electric current can reach more than 5 years the life-span of battery less than 10 μ A.Therefore liquid crystal digital of the present utility model shows that electronic water meter has advantages such as simple in structure, durable in use, metering intensive reading height, little energy consumption again, for quantitative water using water wisely plays an important role.In addition, battery-powered owing to having adopted, be not subjected to the influence of civil power outage when having guaranteed water meter work, thereby obtained using widely.
