Description

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

The present invention relates to a water meter device for preventing freezing.

In general, domestic and industrial facilities measure the usage status of the supplied water and install a water meter in order to charge a fee according to the amount of the water. In the winter season, water meters exposed to the outside The water meter can be frozen as the tap water inside the water pipe is frozen.

1 is a view showing a state in which a water meter 10 is installed in the prior art. Fig. 2 is a perspective view of a conventional water meter 10. Fig.

The conventional water meter 10 is installed in an outer cylinder 6 buried underground. The outer cylinder 6 extends to the ground, and the upper part of the outer cylinder 6 is covered with the lid 7. [

The inlet pipe 1 is for supplying water into the water meter 10 and extends from the ground outside the outer pipe 6 to the inside of the outer pipe 6 and connected to the water meter 10. Water flowing into the water meter 10 through the inlet pipe 1 is discharged to the outside of the outer pipe 6 through the outlet pipe 2. The valve (3) is opened or closed to supply or block water into the water meter (10).

The water meter 10 is composed of a main body 11, a main body inflow pipe 20, a main body outflow pipe 30 and a measuring unit 40.

On both sides of the main body portion 11, a main body inflow pipe 20 into which water flows and a main body outflow pipe 30 through which the water passed through the metering module 40 are disposed are arranged to face each other.

Although not shown in the drawing, the measurement module 40 is provided with a wiper to rotate according to the flow of water, and the rotation of the wiper changes the value of the dashboard indicating the amount of water used by rotating the gear portion.

The water meter (10) is installed near the ground so that the meter reading source can easily check the amount of water used. For this purpose, the inflow pipe 1 is bent upwardly in the lower part of the outer cylinder 6 and extends upward, and likewise the outflow tube 2 is bent downwardly in the water meter 10 to extend downward . As described above, two "a" -shaped bent portions are formed in the inlet pipe 1 and the outlet pipe 2, respectively, so that the structure of the inlet pipe 1 and the outlet pipe 2 becomes complicated, .

The water pressure (minimum (1.5 kgf / cm 2), maximum (12 kgf / cm 2)) is applied to the inside of the main body 11 so as to smoothly supply the tap water supplied through the water pipe embedded in the underground, So that water is filled in the inner space of the main body 11. [

In this situation, the temperature falls below freezing, and the water filled in the body inlet pipe 20 and the body outlet pipe 30 is frozen first, and the water filled in the internal space of the body portion 11 is stagnated, Start. At this time, since the water filled inside the main body 11 is frozen, the volume expansion is necessarily accompanied. However, since the internal space of the main body 11 is not expanded, the water meter is damaged in the process of forming ice .

In order to prevent such freezing, conventionally, a method of wrapping a heating wire on a water meter body or covering a thermal insulating cover with a heating wire has been used.

However, this method has problems such as installation cost of the heating wire, generation of electric power cost due to use of the heating wire, and deformation of the display due to heat generated from the heating wire.

Therefore, rather than adding a new structure, such as applying heat to prevent freezing of the water meter, a new countermeasure, such as modifying the structure of the water meter to fundamentally prevent freezing, is required.

The water meter apparatus (hereinafter referred to as a water meter apparatus) 100 for preventing freeze of the present invention is a water meter apparatus for preventing frost caused by freezing of water by burying a part where water passes through deep into the ground, In order to fundamentally prevent freezing by deforming the structure of the water meter.

The water meter device 100 includes an outer container 110, an inner container 120, a flow guide 130, a flow restriction 140, a rotary vane 145, a first shaft 150, A magnet member 171, a repulsive force generating unit 180, a watertight member 160, and a measuring unit 190. [

The outer vessel 110 can be formed in a cylindrical shape as shown in FIG. 5 and has an inlet 111 and an outlet 112 connected to the water pipes 1 and 2. Water flowing through the water pipe 1 can enter the external container 110 through the inlet 111 and escape to the water pipe 2 through the outlet 112. The upper portion of the outer container 110 may be covered with a lid 111.

The inner container 120 may be formed in a cylindrical shape similar to the outer container 110 and may have an inner inlet 121 and an inner outlet 122 at positions corresponding to the inlet 111 and the outlet 112 of the outer container 110, ).

A seal member 115, 116, 117, 118 such as an O-ring is provided between the outer vessel 110 and the inner vessel 120 so that water introduced through the inlet 111 is supplied to the outer vessel 110 and the inner container 120. [0064]

The flow guide portion 130 is provided in the inner container 120 and designed so that the water introduced through the upper inlet opening 131 flows out through the lower outlet opening 132. A strainer 133 is disposed at a front end of the inflow opening 131 to prevent foreign matter from flowing into the flow guide 130 through the inflow opening 131.

The flow guide portion 130 may have a circular shape and be inserted into the inner container 120. The flow guide portion 130 may be screwed with the inner container 120. This threaded engagement provides watertightness between the flow guide 130 and the inner vessel 120 and allows the flow guide 130 to be easily coupled to and detached from the inner vessel 120.

The inflow opening 131 of the flow guide portion 130 is installed lower than the inner inflow opening 121 so that water introduced through the inner inflow opening 121 can flow into the inflow opening 131 naturally by the flow pressure and gravity. do.

The flow guide 130 may include a plate check valve 135. The plate check valve 135 is located between the lower portion of the outflow opening 132 and the inner outflow opening 122. When the water flows, the spring 135a is contracted by the water pressure to form a flow path. When the water does not flow, The flow path 135a can be restored and the flow path can be closed. This plate check valve 135 enables the flow from the inlet 111 to the outlet 112, but the reverse direction, that is, the flow from the outlet 113 to the inlet 111, can be prevented.

The rotary vane 145 is installed in the inner vessel 120 and rotated by the flow pressure of water. The rotary vane 145 is installed in a space between the inflow opening 131 and the outflow opening 132. The water introduced through the inlet opening 131 can rotate the rotary vane 145 and pass through the outlet opening 132 to escape to the water supply pipe 2 through the internal outlet 122 and the outlet 112.

The flow restricting portion 140 is installed in the inner vessel 120 and restricts the flow of the water, which has entered through the inner inlet 121, to the upper portion above the inner inlet 121. This is to prevent flow loss so that the flow pressure of the water is sufficiently transmitted to the rotary vane 145.

The flow restricting portion 140 and the inner wall of the inner container 120 have a watertight structure so that water is not discharged out of the flow restricting portion 140. The flow restricting portion 140 may have a flat flat portion 140a and a plurality of leg portions 140b extending downward from the flat portion 140a. The leg portion 140b supports the flow restricting portion 140 so that water can flow into the space between the upper portion of the flow guiding portion 130 and the flow restricting portion 140 (or the leg portion 140b).

The flow restricting portion 140 may be provided with an air vent 141. The air vent 141 can discharge the air contained in the water to the outside.

The flow guide portion 130 and the flow restriction portion 140 are configured as separate members. However, the flow guide portion 130 and the flow restriction portion 140 may be formed of a single member. In this case, the flow guide part 130 and the flow restricting part 140 may be connected through the leg part 140b.

The first shaft 150 is connected to the rotary vane 145 and protrudes outside the flow restriction portion 140. The first shaft 150 is rotated synchronously with the rotation of the rotary vane 145. The first axis 150 may have a horizontal extension 151 having a plurality of through grooves 152 formed thereon. The through grooves 152 are spaced apart from the disk-shaped horizontal extension 151 by a predetermined distance.

The second shaft 170 has a plurality of insertion portions 173 inserted into the through grooves 152 of the first shaft 150 and rotates concentrically with the first shaft 150. A horizontal extending portion 172 is formed at the lower end of the second shaft 170 and the insertion portion 173 is integrally formed with the horizontal extending portion 172 and can be extended downward. When the first shaft 150 rotates while the insertion portion 173 is inserted into the through groove 152, the rotational force is transmitted by the contact between the insertion portion 173 and the through groove 152, ).

The magnet member 171 is connected to the second shaft 170 and extends horizontally. A plurality of magnet members 171 may be formed along the second axis 170.

A repulsive force generating portion 180 is positioned below each of the magnet members 171 to generate a repulsive force with respect to the magnet member 171. To this end, the repulsive force generating portion 180 is formed of a magnet, and the magnet member 171 and the repulsive force generating portion 180 have the same polarity.

The plurality of repulsive force generators 180 may be connected to the support member 181 together. The lower portion of the support member 181 is fixed to the upper end of the flow blocking portion 140 and the upper portion of the support member 181 can extend upward along the inner container 120. The upper end portion 181a of the support member 181 is bent in an " a "shape so that the operator can grip and rotate the upper end portion 181a of the support member 181. [ When the operator grasps and rotates the upper end 181a of the support member 181, the entire portion accommodated in the inner vessel 120, that is, the flow guide portion 130, the flow restricting portion 140, the rotary vane 145, The first shaft 150, the second shaft 170, the magnet member 171, and the repulsive force generating unit 180 can be rotated and separated from the inner container 120. This facilitates maintenance of the components contained in the inner vessel 120.

The measuring unit 190 is located above the second shaft 170 and when the rotary vane 145, the first shaft 150 and the second shaft 170 are rotated by the flow of water, . Inside the measuring unit 190, a reduction gear and a guide portion can be positioned.

1, the water meter is installed in a state in which the water pipe is bent upwardly and positioned near the ground. In the present invention, water flowing through the water pipe 1 is almost the same as the water pipe 1 Lt; RTI ID = 0.0 > 140 < / RTI > Accordingly, the water in the water meter apparatus 100 of the present invention is in a position where it does not freeze even in winter, so that no frost is generated. Since the second shaft 170 is elongated in order to place the measuring unit 190 which can be inspected by the measuring probe in the vicinity of the paper surface, the load of the second shaft 170 and the measuring unit 190 is transmitted to the first shaft 150 to the rotary vane 145.

When the flow of water flowing into the inner vessel 120 is weak and the load of the second shaft 170 and the measuring unit 190 is transmitted to the rotary vane 145, The rotary vane 145 can not be rotated at all. In this case, since water is used but the guiding portion of the measuring unit 190 is stopped, an error may occur between the value of the guiding portion and the actual water use amount.

Therefore, in the present invention, a repulsive force generating portion 180 for canceling the gravity of the second shaft 170 is provided to prevent such a problem. The repulsive force generated between the magnet member 171 and the repulsive force generating portion 180 acts as a force for lifting the second shaft 170 upward so that the second shaft 170 and the upper measuring unit 190 are rotated by gravity It may become a zero-gravity state in which it does not operate. The repulsive force generated between the magnet member 171 and the repulsive force generating portion 180 is adjusted to an appropriate value.

Accordingly, even if the amount of water used is small, the rotational force of the rotary vane 145 is transmitted to the first shaft 150 and the second shaft 170 To the measuring unit 190, so that the amount of water used can be displayed through the measuring unit 190.

It is necessary to prevent the water coming in through the inlet port 111 of the water pipe 1 and the external container 110 from flowing into the internal container 120 for maintenance such as replacement and repair of parts in the internal container 120 . An upper plate 123 is provided on the upper portion of the inner container 120 and a grip portion 124 may be provided on the upper plate 123 so that a human can grip the same. 4, the inner container 120 is rotated so that the inner inlet 121 and the inner outlet 122 communicate with the inlet 111 and the outlet 112, respectively, So that it is not communicated. Accordingly, the water entering the inner vessel 120 is shut off, and the operator can perform the necessary work.

Hereinafter, the constructions of the watertight members 160, 160 ', and 160 "of the present invention will be described with reference to FIGS. 6A to 8B.

6A, the first shaft 150 protrudes through the flow restricting portion 140 and the first shaft 150 is synchronously rotated by the rotation of the rotary vane 145, so that the first shaft 150 A small space is formed between the first shaft 150 and the flow restricting portion 140. [ Water can be drained into this space.

In the present invention, a watertight member 160 is provided between the first shaft 150 and the flow restricting portion 140 to prevent this. The watertight member 160 has a housing 161 in which an opening 165 is formed. The first axis 150 passes through the opening 165.

The interior of the housing 161 is filled with the lubricating oil O having a predetermined viscosity. The lubricating oil (O) can be oil, for example grease, which has sticky properties so that water can not easily penetrate.

Due to the nature of water and oil not being mixed well, the water in the flow restricting portion 140 is not well discharged to the outside by only the lubricating oil (O). However, in order to ensure a watertight structure, A first hemispherical portion 155, a second hemispherical portion 156, and a horizontal plate 157.

The first hemispherical portion 155 has a convex shape and may be positioned between the upper end of the housing 161 and the first shaft 150 integrally with the first shaft 150. The second hemispherical portion 156 has a downwardly convex shape and may be positioned between the lower end of the housing 161 and the first shaft 150 integrally with the first shaft 150. The horizontal plate 157 is positioned within the watertight member 160 between the first hemispherical portion 155 and the second hemispherical portion 156 and extends horizontally integrally with the first axis 150.

The watertight member 160 may include a first blocking portion 162 and a second blocking portion 163. The first blocking portion 162 and the second blocking portion 163 may be supported by the support portion 164.

The first blocking portion 162 may extend from the inner wall of the housing 161 to the horizontal plate 157 so as to overlap with the horizontal plate 157 by a predetermined distance. For example, the first blocking portion 162 may extend obliquely downward toward the horizontal plate 157 at the inner wall of the housing 161 above the horizontal plate 157. The first blocking portion 162 may have a predetermined distance from the upper portion of the horizontal plate 157, for example, a distance of about 1 mm (or several mm).

The second blocking portion 163 may extend from the inner wall of the housing 161 to the horizontal plate 157 such that the second blocking portion 163 overlaps the horizontal plate 157 by a predetermined distance. For example, the second blocking portion 163 may extend obliquely upwardly toward the horizontal plate 157 at the inner wall of the housing 161 below the horizontal plate 157. The second blocking portion 163 may have a predetermined distance from the bottom of the horizontal plate 157, for example, a distance of about 1 mm.

Since the hydraulic pressure in the flow restricting part 140 is applied to the first semi-spherical part 155 and the second semi-spherical part 155 by the hydraulic pressure, The second hemispherical portion 156 is also subjected to upward force.

Referring to FIG. 6B, when the first shaft 150 is slightly raised by this force, the first hemispherical portion 155 and the housing 161 are in contact with each other. As a result, further upward movement of the first shaft 150 is blocked and the upper opening 165 is closed to block the flow of water in the flow restriction section 140. However, the lower opening 165 may be larger, but the inside of the housing 161 is filled with the lubricating oil O, so that there is no big problem.

Further, when the first shaft 150 slightly rises, the horizontal plate 157 and the first blocking portion 162 come into contact with each other, so that the discharge path of the water can be further blocked.

When the first shaft 150 descends, the second hemispherical portion 156 contacts the housing 161 or the horizontal plate 157 and the second blocking portion 163 come into contact with each other and the first shaft 150 ) And the discharge path of the water can be blocked.

Referring to Figure 7a, which illustrates another embodiment, a first hemispherical portion 155 and a second hemispherical portion 156 are provided on a first axis 150 and a bearing 166 'is provided on the watertight member 160' Can be provided. The inside of the housing 161 'is filled with lubricating oil O.

The first hemispherical portion 155 and the second hemispherical portion 156 have the same configuration as the embodiment shown in Fig. 6A. The bearing 166 'is located within the watertight member 160' and supports the rotation of the first shaft 150.

As shown in FIG. 7B, when the first shaft 150 is raised, the first hemispherical portion 155 and the housing 161 'are in contact with each other. Accordingly, the upper opening 165 'is closed to block the further upward movement of the first shaft 150 and the flow of water out of the flow restricting portion 140.

Referring to Figure 8A, which shows another embodiment, an opening 165 "is provided between the housing 161" and the first axis 150. [ The inside of the housing 161 " is filled with the lubricating oil O. [

The watertight member 160 "is provided with a horizontal member 162" extending horizontally from the inner wall of the housing 161 " toward the first axis 150, And a horizontal plate 157 " The horizontal member 162 "and the horizontal plate 157 " overlap with each other by a certain distance with a slight distance up and down. Accordingly, the flow of the water in the flow restricting part 140 is complicated by the overlapping part, thereby blocking the outflow of water.

8B, when the first axis 150 rises, the horizontal member 162 "and the horizontal plate 157 " are in close contact with each other, and the further rise and flow of the first axis 150 So that the flow path of the water in the restriction unit 140 is blocked.

As described above, the water meter device 100 of the present invention is located at a depth where the water flowing into the apparatus through the water pipe does not freeze, and the rotational force of the rotary vane 145 by the flow pressure of the water, 150 and the second shaft 170. The second shaft 170 may be coupled to the second shaft 170. [

The first shaft 150 protrudes out of the flow restricting part 140 through the watertight member 160 and water in the flow restricting part 140 is not discharged to the outside by the watertightness member 160. In addition, since the second shaft 170 can be rotated in a state in which gravity is not applied by the repulsive force generating unit 180, even when a small rotational force is applied to the rotational vane 145, And can be transmitted to the second shaft 170 well.

Accordingly, the length of the second shaft 170 is extended to be close to the paper surface, and the measurement unit 190 is positioned above the second shaft 170, thereby making it possible to easily meter the probe. Therefore, the water meter apparatus 100 of the present invention can measure the amount of water used without freezing water inside the apparatus even during the winter season.

In addition, in the water metering apparatus 100 of the present invention, the flow of water flows from the top to the bottom inside the inner vessel 120 (in the conventional water meter, the flow of water rises from bottom to top) , Which makes it much easier to precisely measure.

In the present invention, the outer container 110 and the inner container 120 are separately described. However, the outer container 110 and the inner container 120 may be replaced by one container. In this case, means for closing the inlet may be added, and such means can be practiced by a person skilled in the art in various ways, such as by providing a valve structure.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention will be.
