The water supply pipe 110 is a component that is supplied with water to the inside and discharged to the outside of the upper end, and a first screw thread 113 is formed at the lower end thereof. The replacement nut 125 of the first fastening member is a cylindrical member having a nut screw thread 123 screwed with the first screw thread of the water supply pipe formed on an inner circumferential surface and a rubber packing 126 on the outer circumferential surface.

The replacement nut 125 is shown in FIG. 3, and has a through hole so that water can flow, and a cylindrical body 125a having a thread formed on the upper inner surface and a ring-shaped protrusion formed on the outer peripheral surface thereof ( 125b). The diameter of the ring-shaped protrusion has a structure that increases upward, so that the replacement operation is facilitated when the water supply pipe is replaced.

The internal injection member 120 is shown in a perspective view and a cross-sectional view in 4A and 4B, and in FIG. 5, a cross-sectional view of the inner injection member 120 is shown. The inner injection member 120 is positioned by being inserted into the interior of the housing 150, but on the outer circumferential surface of the body 120-1 of the inner injection member, a wing part protruding from the outer surface so as not to be in close contact with the housing and extending in the vertical direction Has (120-2). A plurality of the wing portions are spaced apart at predetermined intervals in the radial direction. In addition, a lower protrusion 120-3 is provided at a lower portion of the body 120-1 to protrude and having a thread (not shown) for fastening a water pipe therein. In addition, the replacement nut 125 and the rubber packing 126 are fastened to the inner cylindrical inner space 120S of the inner injection member 120.

4B, an outlet hole 120a is formed on the side of the inner injection member 120, which is to allow water remaining inside the water supply pipe 110 to flow out and discharge to the outside when the water supply pipe is closed. In addition, a filter F is provided between the outer side of the outlet hole 120a and the housing to filter impurities that may be introduced together when the internal residues discharged from the water supply are re-inflowed again.

As shown in FIG. 6, the water supply pipe 110 and the first and second fastening members are integrally fastened, and tap water is supplied from the bottom to the top through the inside thereof. An insulating material 140 is disposed inside the housing 150.

The housing 150 has a housing cap 150-1 on its upper end. The housing 150 and the housing cap 150-1 have a structure that is coupled to be separated from each other, and are coupled by means such as screws (S).

In addition, the housing 150 may be formed of a single stainless steel wall, but is composed of an outer housing 151 forming an exterior and an inner housing 152 located inside for heat insulation of the interior and exterior. Insulation material 153 may be disposed between the and the inner housing. With this configuration, in a structure that absorbs geothermal heat into the housing, which will be described below, an advantageous effect of preventing heat transfer to the outside of the housing can be exhibited while more effectively maintaining the geothermal heat flowing into the housing therein.

And, when the water supply pipe is pulled upward while the first screw thread 113 of the lower end of the water supply pipe 110 and the thread of the replacement nut 125 are fastened, the replacement nut 125 and the rubber packing 126 move upward. While being separated from the inner injection member 120 comes out. That is, the water supply pipe 110, the replacement nut 125, and the rubber packing 126 can be taken out of the housing 150 as it is.

Therefore, in the present invention, it is possible to easily separate the water supply pipe without the need to dig the ground when the water supply pipe breaks down, so that maintenance is convenient. Since only the water supply pipe can be easily separated from the housing and repaired or replaced, there is an effect of reducing work and cost.

[Geothermal absorption structure]

The anti-freezing water supply of the present invention may further include a geothermal absorbing means for absorbing geothermal heat at the bottom of the housing 150 made of stainless and guiding it into the housing, and FIGS. 8 and 9 show the geothermal heat absorbing means of the present invention. have. 8 and 9 are longitudinal cross-sectional views showing the bottom of the housing in which the geothermal heat absorption means is provided.

The geothermal absorbing means includes a heat insulating material 200 mounted at a lower end of the housing 150 and disposed in a transverse direction, and a plate-shaped stainless conductive plate 210 disposed to contact the lower end of the heat insulating material. In addition, it includes a coupling member (230, 240) for coupling the heat insulating material 200 and the conductive plate 210 while in close contact with the outer peripheral surface of the housing 150. The coupling member is positioned on the upper surface of the heat insulator 200 and in close contact with the outer peripheral surface of the housing 150 and the b-shaped first coupling member 230 and the lower surface of the conductive plate 210 made of stainless material. It further includes a b-shaped second coupling member 240 in close contact with the outer peripheral surface of the housing 150 while being positioned. The second coupling member 240 is made of stainless steel.

In the figure of FIG. 8, the first coupling member 230 and the second coupling member 240 have a structure in direct contact with the housing 150. However, it is not limited to this structure, and the first coupling member 230 and the second coupling member 240 on the outer circumferential surface of the second fastening member 130 present outside the housing 150 shown in FIG. 5. ) May be formed to be combined. In this case, the second fastening member 130 will also be made of stainless steel.

By the above structure, it is a structure in which underground geothermal heat is introduced into the housing by the heat insulating material 200 and the conductive plate material 210. Since the geothermal heat under the heat insulator 200 is blocked from heat transfer to the top by the heat insulator, heat that cannot move to the top of the heat insulator is located under the heat insulator. In addition, the conductive plate 210 provided in the shape of a flat plate under the insulating material serves as a medium for transferring (conducting) such geothermal heat. So, the underground heat under the insulating material is transferred to the conductive plate, the conductive plate conducts heat to the second coupling member 240, and the second coupling member 240 is in close contact with the housing 150 of the same material. Therefore, in the end, geothermal heat is transferred to the housing. The arrows in Fig. 8 schematically illustrate the flow of geothermal heat transfer.

In FIG. 9, as the conductive plate material has a structure capable of transmitting more geothermal heat, a geothermal branch portion 215 protruding downward is further provided at an outer lower end of the conductive plate material 210. Since the geothermal branch is buried deeper in the ground, more geothermal heat can be transmitted from the ground, and as a result, more heat can be transferred to the housing 150 through the conductive plate material 240 and into the housing. Through this, the water supply pipe existing inside the housing is maintained without freezing even in the cold season in winter.

The effect of this heat conduction was proved to be excellent as a result of directly verifying the heat transfer effect into the housing as a result of comparing the case where the applicant directly buried the conductive plate and the insulation material in the ground and not.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements by those skilled in the art using the basic concept of the present invention defined in the following claims are also present. It belongs to the scope of rights of
