Detachable Water Meter {Detachable Water Meter}

The present invention relates to a water meter.

The background technology is shown in Figure 5 and is the Republic of Korea Intellectual Property Office Patent Registration No. 10-2457234 (2022.10.20).

As a background technology, as shown in FIG. 5, a water meter 2 is installed inside and a pipe inlet 11 and a pipe outlet 12 are installed at the bottom so that the pipe pipe 3 can be connected from the outside. The waterproof structure of the lower part of the water meter protection cylinder in which the main body 1 is formed, and the waterproof assembly 4 is coupled to the pipe inlet 11 and the pipe outlet 12 of the main body 1 to seal the gap. It is a technology about

The main body 10 has a cylindrical shape and is inserted into the pipe inlet 11 and the pipe outlet 12 of the main body 1.

At this time, the part to be inserted corresponds to the upper part of the main body 10, and a step is formed on the outer circumferential surface of the main body 10 so that the insertion depth can be determined.

And the main body 10 is not configured to be directly fixed to the main body 1, and cannot be fixed to the main body 1 with only the configuration of the main body 10, and the fixed body 30 and the fixed cap member 40 are together. should be combined

The sealing body 20 is formed integrally with the close housing part and the pipe housing part and is installed between the fixed body 30 and the main body 10 to close the gap and seal the pipe pipe 3 to be installed. is one composition.

That is, the close housing part is inserted so as to be in close contact with the inner wall surface of the main body 10, and the pipe pipe 3 passes through the hole of the integrally formed pipe housing part.

In order for the close housing part and the pipe housing part to be integrally formed, they must be connected to each other. As shown in the drawing, the lower ends are connected to each other, and the fixed body 30 and the fixed cap member 40 are inserted into the upper space and coupled to each other .

In addition, the sealing body 20 is applied with an elastic material such as rubber, and a band groove is formed outside along the circumference of the upper part of the pipe housing of the sealing body 20, and a separate metal coupled to the outside of the band groove By means of the band, the pipe housing portion and the pipe pipe 3 are deformed into a form in which they are in close contact. In this way, the gap between the piping housing and the piping pipe 3 can be completely blocked by the metal band, so that water or moisture does not flow into the main body 1.

Nevertheless, since the inside of the water meter is still not air-flowing or it is configured in a humidified state, there is still a disadvantage in that it cannot accurately transmit the amount of water used to the repeater due to communication difficulties.

The present invention has invented a separate type water meter to solve these disadvantages.

In addition, conventional meters installed outside are flooded with water protection boxes due to torrential rain and rainy season. As a result, the installed meter often breaks down due to leaks and moisture, and due to negligent management of protective materials to prevent freezing in winter, moisture and freezing may occur while preserving in a damp and wet state.

In particular, corrosion and failure of the meter due to moisture in the protective box occur, and damage to the product in the device installed inside often occurs, causing a decrease in product stability for the digital meter.

In particular, since digital meters are composed of sensitive parts in the surrounding environment, they are prone to malfunction and failure if there are slight changes in humidity and temperature.

Flowmeters such as analog meters and digital meters are impeller-type meters that can measure the flow rate by detecting the number of revolutions of the rotator that rotates when fluid flows through a wing-type rotator. A digital meter, which is a device that can electronically measure the number of revolutions by measuring

Even if the communication system required for wireless remote meter reading required for non-face-to-face meter reading system, which is popular today, is installed, leaks, humidity, and flooding occur in the water protection box, resulting in breakdown of system equipment and communication interference in the water protection box, which reduces the communication rate, resulting in efficient meter reading. There is a disadvantage that the system cannot be operated.

In particular, when the water meter protection box is flooded due to heavy rain and rainy season, a failure occurs that the water meter's viewing window and digital numbers cannot be measured, and flooding of the water meter protection box is a common occurrence in the torrential rain caused by the rainy season that is repeated every year. Because of this, problems arise every year.

Therefore, the present invention measures so that the water meter in the external basement (protection box) can operate normally even in flooding due to the rainy season and torrential rain in summer, and even in cold weather in winter, even at low temperatures such as freezing and bursting of the water meter is to seek

The present invention was invented to prevent efficient communication and flooding and leakage with a separate meter.

The water protection box has a water meter body 400, and is externally connected to the display unit 550 and the digital water meter PCB through the proximity sensor connection part 360.

The wireless remote meter reading terminal 500 at the top of the separated water meter and the wireless remote meter reading system 700 are connected to automatically read the collected data.

The display unit (550: digital pulse digitized data) is displayed in the form of a display unit on the outside of the external protection box.

In the separate type meter, the impeller rotator 220 configured in the meter body 400 configured in the water pipe rotates through the impeller shaft, and the permanent magnet sensor unit 230 and the proximity sensor 310 are configured, and the display unit configured in an external space 550 and a wireless remote meter reading terminal 500.

In the water meter, there is only a proximity sensor 310 for checking the number of revolutions of the impeller rotator 220 made of permanent magnets to check the amount of usage, and all parts of the remaining digital meter are connected to the proximity sensor connection part 360 to It is configured to be separated to the outside through the signal line 370.

It is connected to the meter body 400 through the proximity sensor connection unit 360 through the display unit 550, the wireless remote meter reading terminal 500, which is an external device, and the signal line 370.

The external device constitutes a separate display unit and a wireless remote meter reading terminal in the form of a single board.

In the existing integrated water meter, there has been a difficulty in remote meter reading due to frequent communication disruptions due to interference with wireless communication.

In the existing integrated water meter, there is a disadvantage in that the battery for converting to digital and digitizing the digital pulse on the sight window does not guarantee the meter replacement cycle of 8 years.

However, in the present invention, the battery is to be used in parallel with an external terminal.

There have been malfunctions due to leakage and flooding of proximity sensors and analog and digital conversion sensors of existing integrated water meters, but a system for preventing malfunctions has been implemented by configuring the display unit and wireless remote meter reading terminal 500 externally. can be prevented by

Since all communication system parts are operated by terminals configured externally, communication efficiency is excellent because obstacles to communication interference of the water protection box are removed.

In particular, the battery part can use both the battery inside the water meter and the battery inside the wireless remote meter reading terminal.

It is possible to reduce the size to about 1/5 of the existing water meter.

The upper part of the existing water meter (seeing window and indicator) can also be put together in one board, so the cost of the water meter can be reduced.

It is very advantageous to prevent leakage as the sensor is manufactured in the form of a bolt and nut.
