Abstract
The utility model discloses a non-magnetic gear with a messaging function. The non-magnetic gear with the messaging function comprises a gear body and also comprises a metal rod and a magnetic induction coil; the metal rod is arranged on the integer bit gear corresponding to the gear body; the magnetic induction coil and the metal rod are oppositely arranged. The resistance generated by the mutual action of the magnetic induction element is avoided, and the gear transmission efficiency is improved.
Description
Technical field
The utility model belongs to the technical field of water meter gear, be specifically related to a kind of have the function of posting a letter without magnetic gear.
Background technology
Prior art has 10n (n=integer) m for reaching water meter
3signal output, on the gear that need rotate in correspondence, install a permanent magnet 4 additional, and supportingly near permanent magnet there are one or more magnetic induction components and parts, in the time that gear rotates a circle, the one or more electric signal of the corresponding generation of magnetic induction components and parts meeting, can calculate multi-turn according to the water yield of an electric signal representative and rotate rear water yield simulating signal.
But by calculating the permanent magnet electronic signal that periodically circular-rotation produces, there is following defect in the value that can calculate accumulated water volume by its integer-bit water yield:
Antimagnetic type is poor: owing to having introduced magnet steel, when saboteur is installed additional behind a larger magnetic field in water meter outside, this gear can be inhaled and is parked in certain position, cause Pipeline Water at stream, and gear not walked;
Produce electromechanical reading difference: due to the water meter water pressure fluctuations in use procedure at the scene, water meter reverses sometimes, because permanent magnet is appointed so at circular motion, even if therefore the reading of water meter is reducing, the signal of output is appointed so and is added up up, therefore will produce the water yield of gear instruction and the water yield that electronic signal is collected and produce difference.
Increase the gearing friction power of gear: due to the existence of permanent magnet, a meeting causes gear out-of-level in transmission, can tilt, cause gear drive friction to increase, the 2nd, permanent magnet and magnetic induction part (as tongue tube) produce and do the used time and can produce pulling force, cause water meter slack-off in the time of gear drive.
utility model content
The purpose of this utility model be for the defect of background technology provide a kind of have the function of posting a letter without magnetic gear.
For achieving the above object, the utility model by the following technical solutions:
The utlity model has the function of posting a letter without magnetic gear, comprise gear body, also comprise Metallic rod and magnetic induction coil, described Metallic rod is arranged on integer-bit gear corresponding in gear body, the setting corresponding to described Metallic rod of described magnetic induction coil, answer coil when integer-bit gear driven Metallic rod motion cutting magnetic induction and produce induction electromotive force, by the now speed of gear rotational speed that measures of the voltage to described induction electromotive force and frequency, and then realize the measurement to flow velocity, wherein the threshold value of induction electromotive force is 1.8~3.6V.
Described Metallic rod is without magnetic Metallic rod.
The utility model is because metal device rotates in the direction by different, cutting magnetic line can produce different electromotive force, therefore solved smoothly and in the time of reversion, encountered machinery, electron number difference, its scheme proportion is measured flow velocity simultaneously, not affected by external magnetic field, on this basis, break away from the resistance of the interaction generation of magnetic induction part, improved the transmission efficiency of gear.
Brief description of the drawings
Fig. 1 is the utility model overall construction drawing.
Embodiment
Details are as follows in conjunction with legend for this specific embodiment:
Fig. 1 has expressed overall architecture of the present utility model.
As shown in Figure 1, the utlity model has the function of posting a letter without magnetic gear, comprise gear body, also comprise Metallic rod 4 and magnetic induction coil 5, described Metallic rod is arranged on integer-bit gear 1 corresponding in gear body, on 2 or 3, the setting corresponding to described Metallic rod 4 of described magnetic induction coil 5, when integer-bit gear driven Metallic rod motion cutting magnetic induction answers coil 5 to produce induction electromotive force, by the now speed of gear rotational speed that measures of the voltage to described induction electromotive force and frequency, and then the measurement of realization to flow velocity, wherein the threshold value of induction electromotive force is 1.8~3.6V.
Described Metallic rod is without magnetic Metallic rod.
The flow-measuring method without magnetic gear with the function of posting a letter is as follows: magnetic induction coil 5 produces induction electromotive force under the effect that is subject to Metallic rod periodicity cutting magnetic line, detection obtains voltage and the frequency of magnetic induction coil induction electromotive force, realize the measurement to flow velocity by voltage and frequency, again according to the final metering that obtains aquifer yield of time parameter, frequency is measured by the magnitude of voltage meeting, frequency and flow velocity (being the speed of cutting magnetic line) are directly proportional, the water yield=flow velocity is multiplied by the time, and wherein the threshold value of induction electromotive force is 1.8~3.6V.
It is more than a specific embodiment of the present utility model; ultimate principle of the present utility model and principal character have been carried out to detailed elaboration; under the scope and real situation that do not depart from this, the change that the utility model is done and variation still belong to this protection domain.
Claims (2)
- One kind have the function of posting a letter without magnetic gear, comprise gear body, characterized by further comprising Metallic rod and magnetic induction coil, described Metallic rod is arranged on integer-bit gear corresponding in gear body, the setting corresponding to described Metallic rod of described magnetic induction coil, answer coil when integer-bit gear driven Metallic rod motion cutting magnetic induction and produce induction electromotive force, by the now speed of gear rotational speed that measures of the voltage to described induction electromotive force and frequency, and then realize the measurement to flow velocity, wherein the threshold value of induction electromotive force is 1.8~3.6V.
- According to claim 1 have the function of posting a letter without magnetic gear, it is characterized in that described Metallic rod is for without magnetic Metallic rod.
