Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing freezing of a water meter,

The present invention relates to a system for preventing freezing of a water meter. More particularly, the present invention relates to a system for preventing freezing of a water meter by generating heat when the temperature of the water meter drops below a predetermined reference value.

In the case of single-family houses, water meters are often installed outdoors. Therefore, there is a lot of accident in the water meter in winter.

Passive methods using thermal insulation or insulating materials are also used to prevent such accidents, but they are not expected to be effective in a subzero temperature environment.

Accordingly, a method has been proposed in which a temperature sensor and a heat source (for example, a heating line) are installed to raise the temperature when the temperature of the water meter drops below a predetermined reference value.

Patent Document 1 is an example thereof.

In the apparatus for preventing frost damage in a tap water meter in Patent Document 1, a heating wire is disposed on a bottom surface of a water meter or a water meter lid, and a temperature sensor is installed to sense a temperature and apply a current to a heating wire when the sensing temperature is below a set temperature.

However, in the water meter prevention device of the water meter of Patent Document 1, power supply is required. In order to perform the wiring work for connecting the power line to the water meter prevention device for outdoor water meter, it is necessary to construct a large scale and it may be costly.

In order to solve these problems, there is proposed a method of generating electric power through solar power generation and supplying electric power to the water hammer prevention device, but this method is also expensive.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that the invention is not intended to be limited to the particular embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The terminology used in this application is used only to describe a specific embodiment and is not intended to limit the invention. The singular expressions include plural expressions unless the context clearly dictates otherwise.

Fig. 1 is a conceptual diagram of a water metering damper preventing system according to the present invention.

In the present invention, the water meter (22) is located inside the meter box (20).

The water metering device 22 is provided in contact with the freeze protection device 30. The freeze prevention device 30 includes a temperature sensor 31 and a heating body 32 for measuring the temperature. Accordingly, when the measured temperature of the temperature sensor 31 is lower than a predetermined reference value, heat is generated through the heating element 32, thereby preventing the water meter from being frozen.

A connection line 40 is connected to the freeze protection device 30 and the connection line 40 is connected to the inside of the building through the water pipe 10 to receive power. And a control device 35 is connected to the connection line in the room to control the device for preventing the freeze. At this time, the user may check the temperature of the water meter box or change the set temperature through the control device 35 of the frost protection device. However, the indoor control device is omitted, and the control device of the freezing prevention device 30 may be installed in the freezing prevention device inside the meter box.

The control device can be equipped with an IOT chip to enable communication. If the control device can communicate via the IOT chip and the water meter is an electronic meter, remote meter reading (meter reading at a remote location) can be implemented. You can also remotely determine if there is a failure. For example, if it is understood that the measurement result of the temperature sensor 31 is maintained at a sub-zero temperature for more than one hour, it can be estimated that a malfunction has occurred in the freezing prevention device 30.

In order to check the temperature of the water meter box in the control unit 35, a display unit capable of displaying the temperature must be formed in the control unit 35.

It is preferable that the freezing prevention device and the heating element are waterproofed.

The connection line 40 includes an electric wire for supplying electric power. In this case, leakage may occur around the water pipe, and a short circuit may occur in the connecting line. Therefore, it is preferable to supply 12 V of AC voltage rather than AC voltage of 220 V (the connection line is surrounded by the insulator, There is a possibility of peeling off). An adapter is required to receive 12 V AC from the room power source.

The connecting wire may include a ground wire.

In addition, when transmitting / receiving a control signal through the control device 35 in the room, it may include an electric wire for transmitting / receiving a control signal.

The connection line can receive power supply by connecting the plug 36 to an outlet in the room. Alternatively, the connection line may be connected to an indoor power line to receive power.

As shown in FIG. 1, when the connecting line is installed, the connecting line 40 can be installed through the water pipe 10 with relatively simple construction, so that the connection line installation cost can be reduced.

The water pipe 10 is a pipe through which tap water flows. In order to install the tap water as shown in FIG. 1, a metering pipe branch 50 is installed in the water pipe on the meter housing side, and an indoor branch 60 is installed in the water pipe inside.

The meter branching section (50) and the indoor branching section (60) do not interfere with the flow of tap water in the water pipe. However, the meter branching section 50 is provided with a branching branch 51 of the metering branch, and the branch branching hole 61 is formed in the branching section 60 of the room 60, 40).

The metering branch portion lid 55 is covered in the metering branch branching hole 51 so as to prevent the tap water from leaking into the metering branch branching hole 51 and the indoor branching branching hole 61, (61) is covered with an indoor branch cap (65).

The metering branch lid 55 can seal the metering branch branching hole 51 with the connecting line 40 passing through the metering branch branching hole 51.

The indoor branching lid 65 can seal the indoor branching branch hole 61 in a state where the connecting line 40 passes through the indoor branching branching hole 61. [

The connection line should not be corroded by long exposure to tap water in the water pipe and should be made of a material that does not release harmful components. Accordingly, the connection line 40 may include a flexible stainless steel sheath or may be inserted into a stainless steel pipe. Alternatively, the covering of the connecting wire may be made of polyethylene or PVC.

Various methods may be used to penetrate the connection line between the meter branching section 50 and the indoor branching section 60.

The first method is to draw the water inside the water pipe and then insert the connection wire into the water pipe by pulling the connection wire at one end of the wire which is passed first by using a thin and stiff wire.

The second method is a method using a moving object.

The moving object is a spherical object that has a density similar to that of water. When the moving object is poured into the water pipe and water is shed, the moving object moves along the water flow direction. At this time, the moving object may be shaped like an umbrella, not a spherical shape. If you have an umbrella-like shape, you can more effectively receive the force that moves by the flow of water. If the moving body is made umbrella-shaped, the connecting line can be connected to the first handle portion.

2 is a view showing a state where a connection line is inserted into a water pipe by using a mobile body.

After the connection line is fixed to the moving body 70, when the water flows in the arrow direction, the moving body moves in the arrow direction.

With the second method, even if the water pipe between the meter branching section 50 and the indoor branching section 60 is not straight, the connecting line can be easily inserted into the water pipe.

Therefore, the second method involves the following five steps.

(1) Step 1: Fixing the end portion of the connecting line to the moving body

(2) Step 2: Step of inserting the moving body into the branched branch hole of the meter

(3) Third step: Water is flowed into the water pipe to move the moving body to the indoor branched branch hole

(4) fourth step: extracting the moving body into the indoor branching branch hole

(5) fifth step: separating the end portion of the connecting line from the moving body

After the fifth step, the end of the connecting line may be connected to the control device 35 in the room or to the plug 36 in the room.

A third method is to use a mobile body, not to directly connect the connecting line to a moving body, but to connect a string such as a fishing line through a water pipe by using a connecting line, and then to connect the connecting line through the water pipe by using the string. A string such as a fishing line is thinner and easier to swivel than a connecting line, so it is more advantageous than a connecting line to penetrate a water pipe.

Therefore, the third method involves the following seven steps.

(1) Step 1: Fixing the end portion of the string to the moving body

(2) Step 2: Step of inserting the moving body into the branched branch hole of the meter

(3) Step 3: The water is flowed into the water pipe to move the strap to the indoor branch branch hole (at this time, the branched branch hole of the meter branch may be blocked so as to prevent water from leaking into the branched branch hole of the meter) The length of the length corresponding to the distance from the diverging hole of the meter branch to the branching hole of the indoor branching part can be put in advance in the water pipe so that even if one end of the string is fixed to the diverging hole of the meter branch, It is not disturbed when moving to the branch hole)

(4) fourth step: extracting the moving body into the indoor branching branch hole

(5) Step 5: separating the end portion of the string from the moving body

(6) Step 6: fixing the end portion of the string to the connecting line

(7) Step 7: a step of pulling the string and pulling the connecting line so as to penetrate the connecting line through the water pipe (i.e., pulling the strap to penetrate the connecting line between the indoor branching portion and the meter branching portion)

After the seventh step, the end of the connection line may be connected to the control device 35 in the room or to the plug 36 in the room.

If there is a check valve in the water pipe, water pollution due to backflow of the water pipe can be prevented. The meter branching part (50) or the indoor branching part (60) according to the present invention may include a check valve.

The meter branching part 50 and the indoor branching part 60 in FIG. 1 are formed by cutting a part of the water pipe 10 and connecting a separate device (meter branching part 50 and indoor branching part 60) It does not mean only cases. If a portion of the water pipe is simply pierced so that the connection line 40 can be inserted into the water pipe, it can be referred to as a meter branching unit 50 and an indoor branching unit 60.

Therefore, the conceptual diagram of FIG. 1 may be displayed as shown in FIG.

Fig. 3 is another example of a conceptual diagram of a water metering damper prevention system according to the present invention.

As shown in Fig. 3, a portion of the water pipe 10 in the meter box 20 may be pierced to make a branching branch 51 of the meter branch. The water pipe 10 may be sealed by inserting the connection line 40 into the branch branch hole 51 of the meter and covering the meter branching lid 55. At this time, a portion of the water pipe 10 where the branch branch portion 51 of the metering device is located is a metering branching portion.

Further, as shown in Fig. 3, a hole may be formed in a part of the water pipe 10 in the room to form the branch branch hole 61 of the indoor branch. The water pipe 10 may be sealed by inserting the connection line 40 into the indoor branch branching hole 61 and covering the indoor branching lid 65. At this time, a portion of the water pipe 10 where the indoor branching branch hole 51 exists is the indoor branching portion.

When sealing the water pipe 10 by covering the meter branching lid 55 or the indoor branching lid 65, it is possible to use an adhesive or the like, or it may be combined using a screw thread (that is, It can be made and fixed with a combination of threads), rubber packing can also be used. In addition, the meter branch portion lid 55 and the indoor branch portion lid 65 may be omitted and sealed using only an adhesive agent. That is, the water pipe can be sealed in various ways as required.

Since the 'meter branch' is located outside (outside the building), it may be called 'outdoor branch'. In this case, the branching hole of the meter branching part can be called as the branching hole of the outdoor branching part, and the cap of the branching part of the meter can be called as the lid of the outdoor branching part.

When the remote meter reading function according to the present invention is implemented, it may be implemented without a freeze prevention device. That is, in the state that the water meter is not equipped with a frost prevention device, the connection line can be passed between the water pipes for inspection of the electronic meter.

At this time, the connection line includes a wire for transmitting meter reading data or a wire for supplying electric power to the electronic meter.

Therefore, it is possible to modify it as in the first and second modified embodiments of the present invention.
