The present invention relates to a floating water tank having a freezing function in winter, and more particularly, to an internal storage floating water tank structure to improve the problem caused by the external discharge of residual water when using the water bottle and to make it easier to use. It is about.

In general, a floating water supply is a water supply to prevent freezing and freezing by a cold wave in winter, and the conventional technique for such a floating power is to improve the internal structure of the floating power and the floating power itself by using insulating means for valves and pipes. Although it can be roughly classified as a passive warfare, it is known that the latter method is preferable for effective freezing prevention in winter cold weather.

Looking at Korean Patent Application No. 2003-42549, which was filed by the applicant as an example of the conventional floating water bottle according to the latter, is provided with two valves (faucet, floating valve handle) in the front and rear respectively, the rear in summer The floating valve is operated to open and close the water supply by operating only the front faucet in the open state.In winter, the water supply can be opened and closed by operating only the floating valve handle at the rear with the front faucet open. The remaining residual water was introduced to the bottom to prevent winter water freezing in the water supply line.

In particular, the prior art has a structure in which the discharge hole is formed so that the residual water induced in the lower portion is discharged to the outside to penetrate the soil.

However, for the construction of the conventional floating water supply, with the inconvenience of installing a gravel layer around the valve for the smooth discharge of residual water, soil discharge may occur due to the discharged residual water, and the amount of water discharged. There was a problem that loss occurs.

In addition, since the two valve structure is formed, the valve opening and closing method is different according to the summer and winter, it is necessary to separate management, thus causing an uncomfortable effect on use as a public facility.

The present invention has been proposed to improve the above problems in the prior art, it is possible to prevent soil contamination as well as water loss by allowing a separate storage can be made from the inside without discharging the residual water remaining in the water supply to the outside. The purpose is to make it work.

In addition, another object of the present invention is to provide a single number of valves for opening and closing the flow path to facilitate the use of floating power.

The purpose is that the water supply pipe is connected to one side of the constant water supply, the floating valve housing is provided with an opening and closing opening for opening and closing the flow path, the lower end is connected to the floating valve housing, the upper end of the constant supply to the outside A water supply main configured with a faucet connected to the water reservoir, a reservoir provided in the floating valve housing, a storage valve body configured to move up and down for opening and closing the opening and closing opening, and a driving means connected to an upper portion for driving up and down the storage valve body. It is possible to achieve through the discharge water storage internal floating water column, characterized in that configured.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is an external perspective view of the floating water column according to an embodiment of the present invention, Figure 2 is a detailed cross-sectional view of the floating valve housing portion of the floating water column of the present invention, Figures 3 to 5 show the operational state diagram of the floating water column of the present invention, respectively 6 is a cross-sectional view showing the branch structure of the faucet according to the application of the present invention, Figure 7 is a cross-sectional view showing the operating state when using the drinking fountain.

First, referring to the overall structure of the floating water column according to the present embodiment, the floating valve housing 10 located at the bottom of the apparatus is provided with a water pipe connection part 11 to which a water pipe is connected, and the opening and closing of the flow path therein. In order to support the opening and closing 12 is elastically supported by the elastic spring 13, the pressing projection 12a protrudes to a predetermined height on the opening 12.

And, the water supply column 20 is installed upright so as to communicate with the constant flow path in the floating valve housing 10, the faucet 30 is open is connected to the water supply line 20, the water supply line ( 20) transparent or translucent water can be made of opaque material so that the change of residual water can be confirmed.

In particular, the floating valve housing 10 of the present invention includes a water storage chamber 15, and the water storage valve body 40 maintains water tightness while the water storage valve body 40 opens and closes the flow path of the opening / closing opening 12. It is configured to be in close contact with the inner wall of the reservoir 15 so as to be able to move up and down, and a stopper 14 for supporting a falling height of the reservoir valve body 40 at one lower end of the reservoir 15 to secure the flow path. It is done.

On the other hand, as the elevating drive means connected to the upper portion of the water storage valve body 40 is a rod-shaped handle bar 41 is configured in the handle bar protection pipe 42, the upper end of the handle bar 41, the hinge 51 A valve handle 50 that can be pivoted about the center is connected via a link 52.

In addition, the water pipe connection part 11 is configured with a non-return valve 16 that is elastically supported by the elastic spring 17 to prevent the reverse flow of the constant flowed into the floating power when the water is generated.

And, as an application of the present invention, the faucet 30 has a negative outlet 31 is branched upward as shown in Figs. 6 and 7, while the flow path branch is elastically supported by a spring 38 in the spout flow path Switching valve 35 for selectively switching the was configured.

A drain hole 32 for discharging water remaining therein is formed in the lower portion of the drinking hole 31, and a drain valve 33 for opening and closing the drain flow path is elastic by the spring 36 in the drain hole 32. Is supported.

Drawings, reference numeral 34 is a tightening of the binary is signed to prevent separation of the drain valve 33 is old, and 37 represents an exponent packing for maintaining watertightness.

The operational effects of the use of the present invention floating water column having such a configuration will be described through the operation state diagram of FIGS. 3 to 5.

Floating water supply of the present invention is mainly suitable for installation in a public place, such as a park or bus station, so that a large number of citizens can easily use the constant, when not in use, as shown in Figure 3 the valve handle 50 is in place of the constant The supply is closed and the flow path is closed.

That is, in this case, since the water storage valve body 40 in the floating valve housing 10 is raised, the opening / closing opening 12 is elastically supported upward by the lower elastic spring 13 to block the flow path. .

On the other hand, the user must operate the valve handle 50 in order to receive a constant, and as the first stage opening operation, as shown in FIG. 4, when the valve handle is folded about 90 degrees with the hinge 51 as the axis, the link ( The handle bar 41 and the water storage valve body 40 which are connected by 52 are lowered and come close to the pressurizing protrusion 12a of the opening and closing port 12.

At this time, since the valve handle 50, the link 52 and the handle bar 41 are in a straight line and the position of the valve handle 50 is not fixed, if the valve handle 50 is released in this state, The elastic spring 13 is in place by the elastic force.

Then, when the valve handle 50 is completely bent, the water storage valve body 40 is further lowered as shown in FIG. 5 as a two-stage opening operation, thereby pressing the opening and closing port 12.

As a result, the opening and closing hole 12 on which the pressing force is applied is opened, and thus the flow path is opened, so that the constant water supplied through the water pipe (not shown) is supplied to the water supply column 20.

That is, as the opening of the flow path is made according to the lowering of the opening and closing hole 12, the constant water is supplied by the strong water pressure, and the water is discharged through the faucet 30. At this time, the water storage valve body 40 and the water storage chamber 15 ) Due to hermeticity with the inner wall surface, the inflow of the constant water is not made into the reservoir 15.

In addition, when the constant discharged through the faucet 30 is a drinking water band as shown in Figure 6 and 7, which is an application example, the switching valve 35 is normally raised by the elastic force of the spring 38 Since it is possible to use as a faucet as shown in Figure 6, by pressing down the switching valve 35, as shown in Figure 7a it becomes possible to use the negative supply by branching the supply flow path to the negative port 31 side. At this time, the drain valve 33 is lowered while pressing the spring 36 due to the constant water pressure supplied to form a state in which the drain hole 32 is closed by contacting the exponent packing 37.

On the other hand, when the supply of the constant water in the negative water is stopped, the water remaining inside is dropped through the drain hole 32 is discharged to the outside.

That is, at this time, since the hydraulic pressure for pressing the drain valve 33 is released, the drain valve 33 is raised by the elastic force of the spring 36 to be spaced apart from the exponent packing 37 and the drain hole 32 is opened. As a result, the water remaining in the drinking port 31 is discharged.

Meanwhile, when the valve handle 50 is positioned at right angles to stop the discharge of the constant water during use, the water storage valve body 40 which is pressing the opening / closing opening 12 again as shown in FIG. As it rises, the opening / closing opening 12 closes the flow path by the elastic force, so that the constant water supply is stopped.

Subsequently, when the valve handle 50 is completely returned to the original position as shown in FIG. 3, the reservoir 15 having a predetermined volume is formed in the floating valve housing 10 according to the rise of the reservoir valve body 40. Residual water remaining in the water supply tank 20 without being discharged through the faucet 30 is quickly introduced into the reservoir 15, it can be seen that no water remains in the water supply tank 20.

Then, when the valve handle 50 is lifted up again for use of the constant and sequentially operated as shown in FIGS. 4 and 5, the water storage valve body 40 is lowered and the water stored in the water storage chamber 15 is lowered. Press again to move to the water supply column 20 side, and then open by pressing the opening and closing port 12 in accordance with the continuous lowering operation is to supply the constant as described in the operation description.

That is, the residual water remaining in the water supply column 20 is temporarily stored in the water storage chamber 15 at the time of closing the flow path, and thus can be used again as supply water, thereby saving the constant.

On the other hand, if a sudden shortage occurs in the process of connecting the hose to the faucet (30) to store the constant in a separate water tank, the water in the water tank can be flowed back through the hose and back to the water pipe, but at this time to prevent backflow The occurrence of back flow can be prevented by the valve 16, thereby essentially blocking back water from contaminating raw water.

 And while specific embodiments of the present invention have been described and illustrated above, it is obvious that the floating water column structure of the present invention may be variously modified and implemented by those skilled in the art.

For example, in the above embodiment, a valve handle structure in which a link connection is made as a lift drive means of the water storage valve body has been described, but the handle opening / closing structure is configured to be used in the form of a pedal or a pedal using a foot. You can do it.

Therefore, such modified embodiments should not be understood individually from the technical spirit or the prospect of the present invention, and such modified embodiments should fall within the appended claims of the present invention.

In the present invention as described above, the residual water remaining in the water supply when the valve is shut off is quickly moved to the storage chamber provided therein to be temporarily stored, thereby preventing the freezing of the winter season and at the same time soil contamination due to residual water leakage It will have the effect of preventing.

In addition, the residual water has been temporarily stored can be reused in the constant water supply to save water use.

In addition, since the process of constructing the gravel layer is not necessary to facilitate the external discharge of the existing residual water, installation workability can be more easily achieved.

In addition, the opening and closing of the flow path and the internal residual water can be controlled by using one valve, so that anyone can use it easily.
