The present invention relates to a freeze prevention stone drinking fountain, and more specifically, before the water supply pipe is frozen in winter, an operation bar operated by an increase in the volume of the operating water due to freezing automatically drains the negative water in the water supply pipe in a small amount, thereby freezing the water supply pipe. It is related to the freezing prevention stone drinking fountain that can prevent the accident in advance.

In general, the water inside the water supply system (water valve, meter, pipe, etc.) is frozen by the external temperature under the condition that water is not used during the cold season, causing freezing of the water supply system.

However, the method of covering the insulation material has the disadvantage that it is inconvenient to manage the insulation material and the insulation effect is weak, so that it cannot effectively prevent freezing and freezing caused by it.

Another method is to open the water valve so that water can be discharged.

That is, in winter, if the water valve is slightly opened to prevent freezing of the water facility, and a small amount of water flows, the water does not stagnate, so the freezing of water and freezing of the water facility can be prevented.

However, in cold weather, it is impossible to open water valves individually in facilities that do not keep warm or outdoors, eventually losing the original function of the water supply and leading to freezing accidents.

It relates to a freezing prevention stone drinking fountain (100) that can prevent it.

The freeze prevention stone drinking fountain 100 of the present invention is largely composed of six parts, which include a drinking fountain body 10, a water supply pipe 20a, a drain plate 40, a bypass pipe 50, and a freeze prevention means. (60).

The drinking fountain body 10 is made of stone and has a structure having an internal space portion SP communicating with the drain pipe 20b buried in the ground.

And a cover 11 is further coupled to the upper end of the drinking fountain body 10, the cover 11 is built-in to be electrically connected to the solar cell 111 coupled to the surface, and the solar cell 111 It has a structure that further includes a secondary battery 112 and a controller 113 electrically connected to the secondary battery 112 .

In addition, the water supply pipe (20a) is installed across the inner space (SP) of the drinking fountain body (10) from the underground.

At this time, the water supply valve 30 is connected to the upper portion of the water supply pipe 20a and is exposed to the outside of the drinking fountain body 10 to control the drinking water.

In addition, the water supply pipe (20a) has a first solenoid valve (SV1) that regulates negative water, and a second solenoid valve (SV1) coupled to a position relatively higher than the first solenoid valve (SV1) to drop negative water into the inner space (SP) It has a structure in which the solenoid valve (SV2) is further coupled.

Here, the first and second solenoid valves SV1 and SV2 are automatically controlled by the control unit 113 depending on whether the operating water is frozen or not.

In addition, the drain plate 40 is also made of stone, coupled to the outer circumferential surface of the drinking fountain body 10 to guide the negative water discharged from the water supply valve 30 to the drain hole 12 formed in the drinking fountain body 10 . do

The bypass pipe 50 is for bypassing and circulating a small amount of negative water in the water supply pipe 20a blocked by the first solenoid valve SV1. It is a combined structure.

And the freeze prevention means 60 is coupled to the bypass pipe 50 to bypass the negative water in the water supply pipe 20a to prevent freezing of the water supply pipe 20a.

The freeze prevention means 60 partially opens the bypass pipe 50 blocked by the working water expanded by freezing in winter, and then discharges a small amount of negative water to prevent freezing of the water supply pipe 20a. .

The freeze prevention means 60 includes a chamber 61 , a freeze prevention valve 62 , a connection pipe 63 , and an operation bar 64 .

Here, the chamber 61 is fixed to be exposed to the drinking fountain body 10, and the operating water is stored therein.

At this time, the chamber 61 may be configured by further forming a heat dissipation fin 611 to increase the surface area so that the negative water in the water supply pipe 20a can be frozen faster.

The freeze prevention valve 62 has a structure coupled to the bypass pipe 50 , and the connection pipe 63 is configured to be mutually connected to the chamber 61 and the freeze prevention valve 62 .

And the operation bar 64 is built into the connection pipe 63 and is configured to be movable inside the connection pipe 63 according to an increase in the volume of the operating water.

At this time, the freeze prevention valve 62 is connected to the operation bar 64 and has a built-in valve body 621 for intermitting the bypass pipe 50 .

Accordingly, negative water in the water supply pipe 20a blocked by the first solenoid valve SV1 is bypassed through the bypass pipe 50, and the bypassed negative water is bypassed through the second solenoid valve SV2 coupled to the water supply pipe 20a. Dropped into the inner space SP of the drinking fountain body 10, and the dropped negative water is discharged to the drain pipe 20b, it is possible to prevent the water supply pipe 20a from being frozen.

Hereinafter, the operation of the antifreeze stone drinking fountain according to the present invention will be briefly described.

4 to 6 are operation views of the freeze prevention stone drinking fountain according to the present invention.

First, when the winter temperature drops sharply, the working water in the chamber 61 through the heat dissipation fins 611 formed in the chamber 61 freezes faster than the negative water inside the water supply pipe 20a.

When the operating water in the chamber 61 freezes and expands, the volume increases, and the operating bar 64 moves by the volume increase of the operating water inside the connection pipe 63 by the expansion pressure of the operating water.

Then, as shown in FIG. 5 , the valve body 621 connected to the operation bar 64 is moved to the moving space 622 formed in the freeze prevention valve 62 to partially open the internal flow path of the bypass pipe 50 . .

At the same time, the detection sensor 631 detects that the position of the operation bar 64 is moved, and the control unit 113 blocks the first solenoid valve SV1 that was opened to distribute a small amount of negative water to the bypass pipe 50 . In this way, the waste of negative numbers can be minimized.

At the same time, the control unit 113 opens the blocked second solenoid valve SV2 so that a small amount of bypassed negative water falls into the internal space SP of the drinking fountain body 10 .

Through this, more reliable operation can be made compared to operation based on only the temperature sensor, and power consumption can be dramatically reduced because the anti-freeze valve 62 is controlled by the number of operations frozen in the chamber exposed to the outside. there will be

Therefore, even if the efficiency of the secondary battery 112 in winter is very low, the secondary battery 112 consumes power only by the detection sensor 631 , the control unit 113 and the first and second solenoid valves SV1 and SV2 . It can be operated with low power.

On the other hand, when the external temperature rises and the operating water in the chamber 61 thaws, the volume of the operating water decreases, and the operating bar 64 is moved into the chamber 61 by the elastic force of the elastic coil 623 and , and at the same time, the valve body 621 closes the internal flow path of the anti-freeze valve 62 so that the bypass pipe 50 is blocked.

At the same time, the detection sensor 631 detects the movement of the position of the operation bar 64 and causes the control unit 113 to open the blocked first solenoid valve SV1, and the opened second solenoid valve SV2 is blocked (shown in Fig. 6)

Then, the negative water flowing through the water supply pipe 20a is discharged only through the water supply valve 30, so that the waste of negative water can be prevented.

As shown in FIG. 7 , for ease of installation and maintenance of the drinking fountain body 10 , it may be configured to be separated into an upper stone 10a , a middle stone 10b and a lower stone 10c .

At this time, the base stone 10d for supporting the lower stone 10c may be buried underground.

In addition, the buried foundation stone (10d) may be made by laying a layer of gravel at the bottom to prevent subsidence.

Here, the drinking fountain body 10 has a structure in which the upper stone 10a, the middle stone 10b, the lower stone 10c, and the base stone 10d are stacked and assembled.

Among them, the upper stone 10a, the middle stone 10b, and the lower stone 10c are divided in half to facilitate molding, and the divided body is made by binding each other through a hinge (joint hinge).

As shown in (a) of Figure 8, the upper stone 10a having a square shape is connected to the coupling piece by adding joint hinges 14 to the two joint surfaces, and corner reinforcement hinges for reinforcement at four inner corners ( 13) can be connected by padding with a coupling piece.

In addition, the central stone material 10b and the lower stone material 10c having a circular shape may be configured by attaching a joint hinge 14 to two joint surfaces, respectively, as shown in FIG.

The embodiments described in this specification and the configurations shown in the drawings are only the most preferred embodiment of the present invention and do not represent all the technical spirit of the present invention, so various equivalents that can be substituted for them at the time of the present application It should be understood that there may be variations and examples.
