Description

Self-powered unit of water supply remote meter reading system {AN INDEPENDENT ELECTRIC POWER DEVICE FOR WIRESS AUTOMATIC METER READING SYSTEM OF WATERWORKS}

The present invention relates to a self-generating device for a remote water meter reading system, and more particularly, it is installed on a tap water inlet pipe of a home or a business that uses tap water to install a power generation system in a water meter that displays the amount of tap water used to drive the electronic system. It is invented to be used as a charging voltage of a battery supplying a voltage.

The conventional water meter has a case body formed with a metering chamber for inlet, outlet, and runner, and the fluid injected from the inlet rotates the runner so that its rotation is metered by a metering mechanism located above the metering chamber. In order to visually see the flow rate, that is, the amount used, is displayed.

In recent years, the structure which attaches a predetermined structure to the front part of the said meter in order to comprise a remote meter reading system is proposed.

This structure is supplied with a driving voltage by a battery as an electronic system.

In this case, however, the electronic system attached to the meter is completely dependent on the power of the battery. The battery has a limited charging capacity. Therefore, if the battery is used for a predetermined period of time, it is necessary to recharge or replace the water supply continuously. You can also see.

Nevertheless, the conventional water meter is not equipped with any device for recharging the battery, so the installer checks the installation or use period of the batteries installed in each water meter to recharge the battery within a predetermined period of time, or There was a hassle that had to be replaced.

For this reason, the efficiency and stability of the remote meter reading system have been greatly influenced, and thus the problem of the hassle and loss of manpower caused by battery replacement has been continuously raised.

Accordingly, an object of the present invention is to provide a battery means of a water meter remote meter reading system to solve the above problems.

In addition, the present invention provides a battery means of the remote meter reading system, the self-power generation device for generating a power corresponding to the amount of water used in the above-described electronic system structure to charge the battery to supply the driving voltage to the various electronic components in normal The purpose of the present invention is to provide a self-powered device of a water meter that can significantly extend the time for recharging and replacing a battery, as well as significantly reducing manpower waste.

Hereinafter, preferred embodiments of the present invention will be described in detail by the accompanying drawings.

Figure 1 shows an exploded perspective view of the water meter in which the present invention device is implemented, the configuration is as follows.

A case body 10 having a metering chamber for receiving the inlet and outlet of the water meter and the runner 11; And a metering wheel 12 located above the metering chamber in which the fluid injected from the inlet rotates the runner and returns at a constant rate according to its rotational movement. And a rotation shaft 13 which is vertically engaged with the metering gear 12 in a state of being installed on the central upper surface of the main body 10. And a permanent magnet 14 joined to the end of the pivot shaft 13. And a coil 16 wound on the core 15 at a predetermined distance away from the permanent magnet 14; And a rectification and charging circuit unit 18 and an image sensor 19 for converting the AC voltage generated by the coil 16 into a DC voltage to charge the battery 17.

Generally, a magnet is an object or device that creates a magnetic field. Its type is a permanent magnet that has a large coercive force in a ferromagnetic material and does not easily lose residual magnetization, and a coil is wound around a magnetic core made of a ferromagnetic material to be resistant to air gaps. Electromagnets that generate a magnetic field, and superconducting magnets that generate a strong magnetic field in a coil by applying a large current to a coil made of a superconductor.

The magnetic field strength of the magnets is about 80 kA / m (= 1 kOe) in permanent magnets, about 0.8 MA / m (= 10 kOe) in electromagnets, and about 8 MA / m (= 100 kOe) in superconducting magnets.

Therefore, small permanent magnets are used for ammeters, rotors and speakers of small generators.

Referring to the operation and effect of the device of the present invention configured as described above are as follows.

First, the permanent magnet 14 having a predetermined size and magnetic force generating force is installed in a state perpendicular to the axis of the runner 11 of the main body 10 to perform a rotational movement at a predetermined rate when the runner 11 is operated. Since it is fixed to (13), when the rotary shaft 13 is rotated due to the use of tap water to rotate with the rotation shaft 13 at a predetermined ratio.

At this time, the permanent magnet 14 is rotated together with the rotation shafts 13 because the core 15 having a "-" shape in which the coil 16 is wound at a predetermined distance from the permanent magnet 14 is installed. When the N pole and the S pole of the permanent magnet 14 are alternately approached to the core 15 and are spaced apart.

However, the position and shape of the permanent magnets and the core can be sufficiently converted within the technically feasible range according to the function and performance.

Figure 2 is an embodiment showing another configuration of the shape of the permanent magnet and the core and the coil.

Therefore, when the magnetic field generated in the permanent magnet 14 forms one closed circuit through the core 15, its direction changes in response to the rotational speed of the permanent magnet 14.

Therefore, the direction of the current induced in the coil 11 wound on the "-" type core 15 is also changed in response to the rotational speed of the permanent magnet 14, so that the alternating current is applied to the coil 16 eventually. Induced.

That is, the permanent magnet 14 fixed on the rotating shaft 13, the "-" type core 15 and the coil 16 is to act as an alternator to generate an alternating voltage when using water. .

Of course, the amount of generation of the AC voltage changes in response to the rotational speed of the rotating shaft 13 and the permanent magnet 14 and the number of windings of the coil 16, the rotational speed of which changes in accordance with the amount of water used.

That is, when the amount of water used is large, the rotational speed of the rotating shaft 13 and the permanent magnet 14 is increased at the same time, and the number of alternating currents induced by the coil 16 is increased.

As described above, the AC voltage induced by the coil 16 is supplied to the rectifying and charging circuit unit 18 and converted into a DC voltage, and then applied to the battery 17, so that the battery 17 is the rectifying and charging circuit unit 18 when water is used. Since the recharging is performed by the voltage outputted from), even though the charging voltage of the battery 17 is partially consumed by the driving of various electronic components, it is replenished slightly every time the water is used, so its life is extended and recharged. And the replacement time can be significantly extended, as well as it can prevent the waste of labor.

As described above, preferred embodiments of the present invention have been described in detail, but those skilled in the art to which the present invention measures the present invention in a meter such as electricity and gas without departing from the spirit and scope of the present invention. It will be appreciated that any modification or alteration of the wheel with the cogwheel may be carried out.

As described above, according to the present invention, by installing a self-generator that performs a power generation function when the water is used in the water meter remote meter reading system itself, the battery that supplies the driving voltage to various electronic components can be charged to this voltage. In addition, the battery can be significantly recharged and replaced, as well as drastically reducing manpower waste.
