Description

The present invention relates to a water quality control device and a water quality control system.

Generally, waterworks use chlorine to disinfect tap water. The residual chlorine concentration of drinking water in the pipes (tap water system) is controlled to be within a specified range. Conventionally, the residual chlorine concentration of drinking water in the pipes is controlled by, for example, a method in which an operator goes to the site and measures the concentration by using a reagent on sample water (see, for example, Patent Document 1).

FIG. 1 is a configuration diagram showing an embodiment of the present invention. FIG. FIG. 4 is an enlarged view of the main part with the lid of the box body removed.

The present invention will be described in detail below based on the illustrated embodiments.
1 to 3 show an embodiment of the present invention. The water quality control device according to the present invention comprises a residual chlorine concentration meter 3 connected to a pipe (tap pipe) 1 so as to communicate with a through hole H of a branch valve J or a repair valve V (previously) attached to the pipe so that a part of tap water flows into the pipe, and a data transmission means 5 for transmitting residual chlorine concentration data measured by the residual chlorine concentration meter 3 to a water quality control department 4.

Specifically, it is equipped with an ultrasonic flowmeter 7 equipped with a flow rate measuring unit 6 that is inserted from a through hole H of a water distribution valve J or repair valve V attached to a pipe 1, and a residual chlorine concentration meter 3 that is connected to the through hole H via a water distribution pipe 8 so that a portion of the tap water flows in.

Reference numeral 26 denotes a fitting having a through hole 26A in the vertical direction, and the lower part of the fitting 26 is detachably attached by removing some parts (such as the handle) of the water distribution valve J and connecting the fitting 26 with a male and female screw 27 or the like. In other words, the hole H and the through hole 26A are connected to each other with the same axis _L1 . A packing (not shown) or the like for watertightness is provided at the connection between the water distribution valve J and the fitting 26.

The ultrasonic flowmeter 7 is equipped with a temperature measuring unit (not shown) that measures the temperature of the water in the pipe 1. The water distribution pipe 8 branches 40 on the way to the residual chlorine concentration meter 3, and has a pressure measuring unit 10 at the end of the branch 41 that measures the pressure of the water in the pipe 1. This allows for lower costs compared to installing a pressure sensor alone.

The data transmission means 5 is configured to be able to transmit flow data measured by the ultrasonic flowmeter 7, residual chlorine concentration data measured by the residual chlorine concentration meter 3, temperature data measured by the temperature measurement unit, and pressure data measured by the pressure measurement unit 10 to the water quality management department 4. The data transmission means 5 has, for example, a communication unit that can be connected to the Internet by wireless communication, and is a controller electrically connected to the ultrasonic flowmeter 7, the residual chlorine concentration meter 3, the temperature measurement unit, and the pressure measurement unit 10. In FIG. 1, 18 indicates electrical wiring.

In the present invention, the ability to transmit each data to the water quality management department 4 means that each data can be transmitted directly or indirectly to a (general) terminal of the water quality management department 4 or to the chlorine injection amount control means 25 of the water quality management department 4. The chlorine injection amount control means 25 is, for example, a chlorine injector 22 having a receiver 21, or a terminal 24 having a control unit 23 for the chlorine injector 22.

In the present invention, "indirectly" transmitting data includes, for example, transmitting to a cloud server. In other words, "indirectly transmitting data to the chlorine injection amount control means 25, etc." includes the case where data is transmitted to the chlorine injection amount control means 25, etc. via a cloud server. Also, "indirectly" transmitting data from the data transmission means 5 to the chlorine injection amount control means 25, etc. includes, for example, the case where data is transmitted from the data transmission means 5 to the chlorine injection amount control means 25, etc. "via another terminal."

The flow data measured by the ultrasonic flowmeter 7, the residual chlorine concentration data measured by the residual chlorine concentration meter 3, the temperature data measured by the temperature measurement unit, and the pressure data measured by the pressure measurement unit 10 are (directly) related to each other so that the correlation between each piece of data can be obtained at a remote location, or each piece of data is related to time (hours) data. In other words, the correlation between each piece of data is configured to be transmitted in advance, or the correlation between each piece of data is calculated at a remote location after each piece of data is transmitted.

As shown in Figures 1 and 3, the residual chlorine concentration meter 3 and pressure measurement section 10 are housed in a box body 11 to form a residual chlorine and pressure measurement unit 12. The residual chlorine and pressure measurement unit 12 is connected to a through hole H of a distribution valve J or a repair valve V. Specifically, the residual chlorine and pressure measurement unit 12 is connected (detachably) via a water distribution pipe 8 branched off from a branch section 28. In Figure 1, 20 indicates a manual valve.

In addition to the residual chlorine concentration meter 3 and pressure measurement unit 10, the box body 11 also contains a pressure reducing valve 14 for reducing the pressure to an appropriate level for the residual chlorine concentration meter 3, a flow control valve 15, a drain pipe 16, and an upwardly opening air vent pipe 17 for removing excess air from the tap water. In other words, the residual chlorine/pressure measurement unit 12 is equipped with the pressure reducing valve 14, the flow control valve 15, the drain pipe 16, and the air vent pipe 17.

Next, the water quality control system of the present invention will be described. The water quality control system of the present invention includes the above-mentioned water quality control device. The data transmission means 5 is configured to transmit flow data measured by the ultrasonic flowmeter 7, residual chlorine concentration data measured by the residual chlorine concentration meter 3, temperature data measured by the temperature measurement unit, and pressure data measured by the pressure measurement unit 10 to the water quality control department 4. The water quality control department 4 is configured to manually or automatically increase or decrease the amount of chlorine (free chlorine, i.e., including sodium hypochlorite and liquefied chlorine (chlorine gas)) injected into the pipe 1 in response to the residual chlorine concentration data received.
The pressure data from the pressure measuring unit 10 is also used for "pipe management." Specifically, tap water distributed from a reservoir is required to be in the range of 0.15 MPa to 0.7 MPa, but if water is distributed at a pressure exceeding this range, there is a risk of causing a water pipe burst, and measures to prevent this are required, such as installing a pressure reducing valve. In particular, when water is distributed under gravity flow at a pressure exceeding this range, constant monitoring is necessary and important, and the pressure data measured by the pressure measuring unit 10 is utilized.

In the present invention, the term "terminal" includes personal computers, smartphones, and tablet terminals.
The present invention is subject to design modifications, and for example, one or both of the temperature measuring section and the pressure measuring section 10 may be omitted. Also, the residual chlorine/pressure measuring unit 12 may be configured to be directly and detachably connected to the distribution valve J or the repair valve V attached to the piping 1.

This makes it possible to measure continuous changes in residual chlorine concentration over time, and to obtain (constantly monitor) residual chlorine data over time at a remote location and increase or decrease the amount of chlorine injected into the piping 1 in a rational and efficient manner.

This makes it possible to measure continuous changes in flow rate and residual chlorine concentration over time, and to obtain residual chlorine data over time in a remote location and increase or decrease the amount of chlorine injected into the piping 1 in a rational and effective manner. In addition, the correlation between flow rate and residual chlorine concentration can be obtained in a remote location, which can be used for water quality management. In addition, no water outage construction is required, and the system can be installed at low cost. In particular, the measurement location can be easily moved and changed.

Therefore, it is possible to measure continuous changes in flow rate, residual chlorine concentration, and temperature over time, and it is possible to obtain residual chlorine data over time at a remote location and increase or decrease the amount of chlorine injected into the pipe 1 rationally and effectively. In addition, it is possible to accumulate highly accurate data on the correlation between flow rate, residual chlorine concentration, and temperature at a remote location.

In particular, the measurement location can be easily moved and changed.

The system is also equipped with a pressure measuring unit 10 that measures the water pressure inside the pipes, and the pressure data measured by the pressure measuring unit 10 can be transmitted to the water quality management department 4 by the data transmission means 5. This allows remote locations to know whether or not there is a risk of the pipes 1 bursting, and can be used as important data for managing the pipes. It also allows remote locations to detect leaks and determine the priority of replacing deteriorated pipes.

The system also includes a residual chlorine concentration meter 3 connected to the piping 1 so that it communicates with the through hole H of a water distribution valve J or repair valve V attached to the piping 1 and allows a portion of the tap water to flow in, and a data transmission means 5 capable of transmitting the residual chlorine concentration data measured by the residual chlorine concentration meter 3 to the water quality management department 4.
