Abstract
This persistent self-powered device for an electronic water meter comprises a rotary impeller and an electric energy generating component, both of which are installed in the water pipe in the outlet section of the electronic water meter. The device is characterized in that the columniform permanent magnet group is installed in the end of the rotary impeller shaft, through which the electric energy generating component is provided and connected with the electric water meter through rectifying voltage regulation circuit. The utility model, with its advantages of safety and reliability, simple structure, easy maintenance, low price and persistent power supply without any replacement, is used in the signaling power supply of the electronic water meter. As for lower power required for signal by the electronic water meter, some electric energy can be used for lighting indication in the event of viewing the measurement of the electronic water meter to observe and determine whether the water meter is in normal operation in the night or in a dark environment.
Description
Technical field
The utility model relates to the measuring instrument of water, i.e. electronic water meter permanence self-power supply device.
Background technology
Water meter is the instrument of cumulative measurement water consumption.For a long time, its charge method all is to adopt the method for manual metering, water supply department cost great amount of manpower, and when manual metering also mistake can often appear.
Electronics metering is in recent years progressively replacing traditional meter reading method, all adopts the method for wired or wireless transmit signal data usually.As IC-card water meter, wired remote-transmission formula water meter, radio remote transmitting water meter, computer intensive data acquisition system or the like; Which kind of electronic water meter no matter, it all needs to keep the work of electronic circuit and the transmission of signal data with power supply.At present, the electronic water meter that domestic all water meter producers are produced, what use basically in the power supply that signal sends is the high-energy battery power supply.But battery is limited service time, need change every certain hour, and especially heavy caliber flow water meter major part all is mounted in hoistway, the well, and environment is comparatively abominable, changes very difficultly, brings many troubles for the maintenance of water supply department; And, bring economically loss to water supply department because the untimely replacing of battery can cause losing of continuous data.
Summary of the invention
The purpose of this utility model is exactly at above electronic water meter power supply existing service time of limited disadvantage, and a kind of electronic water meter permanence self-power supply device of invention.
Principle of the present utility model, being equipped with in water supply pipe exactly can rotary blade, and when having current to pass through in the pipeline, current just promote the impeller rotation, and flowing water flow has just become the mechanical power source of supplying with the electronic water meter power supply in this moment pipeline.
This electronic water meter permanence self-power supply device, comprise that rotary blade part and electric energy produce part, they all are installed in the water pipe of electronic water meter water exit end, it is characterized in that, one end of pivoting leaf wheel shaft is equipped with columniform permanent magnet group, electric energy produces part and is installed in by the permanent magnet group, and electric energy generating unit lease making regulator rectifier circuit and electronic water meter are electrically connected.
The utility model structure can be used as independent generating power supply device, and is supporting used for electronic water meter, also can be directly installed on water delivering orifice one end of electronic water meter, makes it to become one.It is exactly power source that current flow in pipeline, and its impulsion impeller rotation also makes the electric energy generating unit divide the generating work done, and the electric power that it sends just can be used as the permanence power supply of electronic water meter.Adopt the utility model as the sender power supply of electronic water meter, have safe and reliable, simple in structure, easy to maintenance, cheap, power for a long time and need not to change advantage such as battery.Because the required power of electronic water meter signal transmitted is very little, inspect and do the illumination indication so some electric energy can be supplied with the metering of electronic water meter, under night or ambient black situation, observe whether working well of water meter.
