Abstract
The utility model discloses a digital water meter. The digital water meter is mainly characterized in that a meter casing with a magnetic conductor base plate is arranged at an original glass casing on the basis of the existing water meter; a non-metal sensing wheel with permanent magnet steel and an original measuring wheel are coaxially arranged. A bell crank is fixed on the base plate. The horizontal end of the bell crank is provided with a permanent magnet block, and the right-angle end is hinged with a connecting rod with pawls which are connected with a ratchet wheel on a digital counter. The utility model has the advantages of simple structure, convenient manufacture and installation, stable and reliable metering, high sensitivity, flexible regulation, clear and simple reading, unidirectional metering which can prevent cheats, etc. The digital water meter can be used for reforming the existing water meter.
Description
The utility model relates to a kind of application machine effect measurement continuously by the measuring instrument of fluid flow, especially a kind of digital-code type water meter.
Existing tap water metering water meter great majority all are to adopt the gear sensing, the structure that many pointers show.The water meter of this structure is because pointer is many, and how figure place misreads easily, and enters because of there is water on the surface with many pointers, and the long-time back of soaking produces corrosion, fouling even latch up phenomenon, makes meter reading more because of difficulty, and error is also bigger.Chinese patent CN1126824A discloses a kind of " magnetic-armature dry display water-meter ", its primary structure feature is in water impeller and the coaxial installation of magneto magnetometric sensor, magnetic induction type armature is taken turns outside watchcase and the coaxial installation of permanent magnetism magnetic-type magnetometric sensor, and is connected with watchcase worm screw, worm gear and counter wheel outward.It is by the rotation of water impeller and magneto magnetometric sensor, make the outer magnetic induction type armature wheel of watchcase special synchronously thereupon moving and drive worm screw, the worm gear drives counter wheel carries out the metering of discharge.Though this magnetic-armature dry display water-meter has overcome the part defective of how pointer water meter, but it has changed the basic structure of original water meter, and sensing and drive disk assembly are more, complex structure, the internal friction loss is bigger, thereby its sensitivity, accuracy all will be subjected to certain influence.
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art part, provides a kind of simple in structure, and it is convenient to make, install, quantification stability, reliable, highly sensitive, adjust flexibly the digital-code type water meter of clear reading, the anti-cheating of simple and direct and unidirectional metering.
Task of the present utility model can be finished by adopting following technical proposal.On the basis of existing pointer water meter structure, replace former gauge outfit glass shell with the watchcase of being with the magnetic conductor base plate, and on former measurement gear the nonmetal sensing wheel of coaxial mounting strap permanent-magnet steel.Be fixed with a bell crank on the watchcase base plate, its horizontal ends is provided with permanent magnetic iron block and places the permanent-magnet steel phase time of above-mentioned sensing wheel to locate, the right angle end of bell crank is hinged with the connecting rod of a band ratchet and by stent support location, and the ratchet on the described connecting rod is connected with ratchet on the digital counting device.Above-mentioned watchcase can be that whole transparent material also can only offered transparent reading window corresponding to the counter position; Opposite side with respect to permanent-magnet steel on the described nonmetal sensing wheel is provided with a balancing weight, to keep the steady of its rotation; Horizontal ends at bell crank also can be provided with a set screw, is used for adjusting the displacement of permanent magnetic iron block, and then regulates the rotating speed of ratchet sum counter.
Accompanying drawing is the structural representation of the utility model embodiment.
Below in conjunction with embodiment and accompanying drawing wooden utility model is described in further detail.The watchcase 2 of band brass base plate 1 is set at the glass cover-plate place of existing pointer water meter,, is placed with permanent-magnet steel 5 and balancing weight 6 on it relatively symmetrically with position, former end measurement gear 3 coaxial installation one plastics sensing wheels 4.Be fixed with a bell crank 7 on the brass base plate 1 of watchcase 2, its horizontal ends be equipped with by the permanent magnetic iron block 9 of set screw 8 location and place permanent-magnet steel 5 on the sensing wheel 4 the time should locate, described permanent-magnet steel 5 and permanent magnetic iron block 9 are same sex phase time to be placed, and its right angle end is connected with the connecting rod 11 of a band ratchet 10 and in hinged way by support 12 location of supporting.Ratchet 10 on this connecting rod 11 is connected with ratchet 14 on the digital counting device 13, has transparent reading window 15 on the watchcase 2 of answering with these digital counting device 13 phase times.The utility model product is in the process of using, because of the water impact water impeller drives measurement gear 3 and coaxial plastics sensing wheel 4 rotations, permanent-magnet steel 5 on it just produces circular motion thereupon, magnetic conduction effect by brass base plate 1 is delivered to magnetic force on the permanent magnetic iron block 9 in the watchcase 2, make it produce the displacement of periodically upwards takeofing, and make bell crank 7 periodic wobble, and then drivening rod 11 and on ratchet 10 promote ratchets 14 and rotate the stored counts work of finishing.Because the one-way of the corresponding one by one relation of permanent-magnet steel 5 and permanent magnetic iron block 9 and ratchet 14, ratchet 10, make to the utlity model has accurate measurement, reliable and unidirectional metering, the reverse advantage of cummulative metering equally.Can also further adjust its measuring accuracy by set screw 8.
The utility model compared with prior art, have simple in structure, it is convenient to make, install, quantification stability, reliable, highly sensitive, adjust flexibly, clear reading, simple and direct and unidirectional metering can be prevented the characteristics such as cheating, especially are fit to transform traditional pointer-type water meter
