Abstract
The utility model relates to a signal acquisition mechanism for a wet type remote indication water meter and a wet type IC card type water meter of any specification, which mainly comprises a lower clamping board, a gear wheel with magnets, and a circuit board assembly. The circuit board assembly is installed in a rectangular frame of the lower clamping board, and electronic elements are sealed in the frame by the process that both sides of the circuit board assembly are solidified by epoxy resin; the magnets are sealed by using secondary injection molding processing technology; lead-out wires are protected and sealed by rubber sleeves. The signal acquisition mechanism can assure that the water meter can smoothly obtain signals without losing in the process of use, and prevent interference of an external magnetic field, and assure that data of meter reading is correct for the remote indication water meter, and the data of prepayment decreasing is correct for the IC card type water meter.
Description
The utility model relates to wet type remote transmitting water meter and wet type IC-card formula water meter signal acquisition mechanism, and it is applicable to the wet type remote transmitting water meter and the wet type IC-card formula water meter of any specifications and models.
Existing wet type remote transmitting water meter signal acquisition mechanism, all on pointer, place magnet, and make the dividing plate of ability certain pressure of band blind hole with transparent materials such as PC, place tongue tube (or Hall element) in the blind hole, and the magnet contraposition on this blind hole and the pointer, magnets magnetic fields cutting tongue tube (or Hall element) once after pointer rotates a circle, tongue tube (or Hall element) logical (breaking) once just produces a pulse signal, though this structure can obtain signal smoothly, but being subject to external magnetic field disturbs, and profile is not attractive in appearance, and the table lid is installed and had infelicity.
The purpose of this utility model is that providing a kind of at the defective of prior art can gather signal smoothly and can prevent wet type remote transmitting water meter and the wet type IC-card formula water meter signal acquisition mechanism that external magnetic field disturbs.
For achieving the above object, the utility model adopts following scheme: this signal acquisition mechanism comprises lower plate, the gear of magnet carrier and the wiring board assembly of being made up of electronic components such as tongue tube or Hall element and resistance sway, it is characterized in that offering above lower plate one can be for the seat of putting of the gear of mounting strap magnet, the below has and can enclose frame for the rectangle that the wiring board assembly is installed, there is pillar (or establishing step on the limit) to be used for fixing the wiring board assembly in the frame, the wiring board assembly is loaded on and encloses in the frame, the both sides epoxy resin cure, make electronic component encapsulation on the wiring board assembly in frame, do not make moist, guarantee to rotate by magnet, the pulse signal that magnetic field intercepts tongue tube (or Hall element) produces can not be lost and gather smoothly.On extension line, be with gum sleeve, aperture is arranged in the sleeve pipe, little number of perforations is to make according to the radical of extension line, is generally three holes or more than three holes, after gum sleeve penetrates extension line, from inside to outside by the special-purpose screw of watchcase, and pack into successively O type circle, plain washer and hollow screw, hollow screw is screwed in the screw, by plain washer compressing O type circle, make O type circle radial deformation, while banding gum sleeve also seals special hole.
Adopt this mechanism can guarantee in the wet type environment far away change water meter and IC-card formula water meter in use signal can obtain smoothly and not lose, prevent that external magnetic field from disturbing, guarantee that the data data correct, that IC-card formula water meter pre-payment is successively decreased that remote transmitting water meter checks meter are correct.
Description of drawings.
Fig. 1 is the structural representation of this mechanism.
Fig. 2 is the water meter structure synoptic diagram that contains this mechanism.
Fig. 3 is the magnet-wheel synoptic diagram of magnet carrier.
Fig. 4 is the front elevation of gum sleeve.
Embodiment to the utility model is described further below in conjunction with accompanying drawing:
As shown in the figure, gear 7, gum sleeve 8, O type circle 9, plain washer 10 and the hollow screw 12 of the wiring board assembly 2 mainly formed by lower plate 1, by electronic components such as tongue tube 3 or Hall elements of the utility model, the magnet carrier 5 that sways are formed.Wherein lower plate 1 below has a rectangle that the usefulness of wiring board assembly 2 is installed and encloses frame (frame is blind frame), is provided with pillar 13 in the frame or establishes step on the limit of frame to be used for fixing wiring board assembly 2.Have above the lower plate 1 and can put seat 4 for the gear 7 of mounting strap magnet 5, this puts seat 4 is one to recessed blind cylindrical hole, a small boss 6 is arranged, the porose mounting teeth wheel shafts that are used in the middle of the boss 6 in the middle of the blind hole.Magnet 5 revolves and turns around the back and be positioned at tongue tube 3 contrapositions that rectangle encloses frame, magnet 5 magnetic field intercepts tongue tubes 3 once, tongue tube 3 logical (breaking) once (Hall element too) just produce a pulse signal, two tongue tubes (or Hall element) are housed on the wiring board, and wherein one cooperates with electronic section and to play anti-external magnetic field interference effect.When wiring board assembly 2 with lower plate 1 fixedly the time, the two sides all is full of epoxy resin 14, tongue tube 3 electronic components (comprising resistance etc.) such as (or Hall elements) is solidificated in wherein, can guarantee that like this tongue tube 3 electronic components such as grade do not make moist, can not produce displacement yet, guarantee that signal is not lost and gather smoothly because of the vibrations in the external world.The gear 7 of magnet carrier 5 of swaying is made up of the disk of gear and equipped with it magnet carrier.Because gear is a part of water meter counting mechanism, this part is in the wet type state fully, can be hedged off from the outer world fully in order to make magnet, thereby adopt the quadric injection mould processing technology that magnet 5 is sealed in the working of plastics.
The utility model is also protected extension line 11 and is sealed, and extension line 11 adopts gum sleeve 8 protections that have several apertures 15.The several electric wires that have been with gum sleeve 8 are penetrated the special-purpose screw (also can be located at other place) that is positioned at the watchcase water inlet end; and be inserted in O type circle 9, flat circle 10 and the hollow screw 12 filled out successively in the exit; hollow screw 12 is screwed into screw; by plain washer 10 extruding O type circles 9; because O type circle 9 is squeezed and is out of shape to axis direction gradually; endoporus diminishes, and gum sleeve 8 has been protected extension line 11 to seal this hole simultaneously by banding.
