The side surface and the lower surface of the buried box 1 are buried in the basement so that the upper surface thereof is level with the ground surface. 1 and 12, the inner side surface of the buried box 1 protrudes from the upper surface of the buried box 1 along the circumference of the same depth as the side height of the lid 2, May be installed on the upper inner side of the buried box 1 in such a manner as to be seated on the protruding portion of the inner side surface of the buried box 1. 1, the inner space of the buried box 1 has an inner horizontal area at the upper end of the inner side of the buried box 1 from the upper surface of the buried box 1 to a certain depth, Is formed in a shape larger than the inner horizontal area below the side upper end. Due to the shape of the internal space of the buried box 1, stepped protruding portions are formed on the inner surface of the buried box 1. [

As such, the upper surface of the lid portion 2 is also level with the ground surface, like the upper surface of the buried box 1, so that the safety of the pedestrian can be assured. However, depending on the installation environment of the buried box 1 or the intent of the installer, the upper surface of the buried box 1 may be installed higher or parallel to the ground surface. Particularly, it is preferable that the buried box 1 is made of a material excellent in waterproofness and durability, such as concrete, in order to prevent the electric facilities therein from being eroded by underground moisture, water, microorganisms and the like. However, those skilled in the art can understand that the present invention can be made of materials other than those described above. When the buried box 1 is to be buried underground, it is preferable that the buried box 1 is to be installed so that the buried box 1 is not recessed.

The lid part 2 is mounted on the protruding part of the inner surface of the buried box 1 and covers the open part of the upper surface of the buried box 1 to seal the inner space of the buried box 1. 2-9, the lid part 2 is located at the outermost part in the upward direction of the underground buried container system according to the present embodiment, and the upper surface of the lid part 2 is exposed to the outside It serves as a sidewalk or driveway. The lid portion 2 can be made of a rigid material that can withstand the loads of pedestrians, automobiles, etc., and is not deformed under any conditions. For example, the lid portion 2 may be made of metal, reinforced plastic, or the like. Also, the lid part 2 may be made in the form of a box in which a block or the like used for peripheral sidewalks can be mounted for harmony with the surrounding sidewalk.

More specifically, the lid portion 2 is formed so that the periphery of the lid portion 2 and the periphery of the upper surface side open portion of the buried box are hermetically coupled to each other so that the inner space of the buried box 1 is sealed, (3) so that the inner space of the buried box (1) can be ventilated or sealed by the air bag (3). The lid part 2 communicates with the air conditioning part 3 in a sealed state so that when there is no possibility of penetration of rainwater into the built-in appliance 100 for heat radiation of the built-in appliance 100, So that the internal space of the buried box 1 can be ventilated. Since the internal space of the buried box 1 can be ventilated or sealed by only the air conditioning unit 3 as described above, the structure for ventilating or sealing the internal space of the buried box 1 is simple, Not only that, it is very easy to manage the waterproof and cooling functions of underground buried container systems. Referring to Fig. 1, the lid 2 comprises a lid frame 21, an upper plate 22, a lid holder 23, an instrument lid 24, an access lid 25, and a support 26.

FIG. 10-11 is an interior view of the underground buried container system shown in FIG. 1, and FIG. 12 is a cross-sectional view of the underground buried container system shown in FIG. Fig. 10 shows the inside of the underground buried container system in a direction from below when the buried box 1 is removed.

That is, the lid holder 23 has a vertical frame in which the outer surface is brought into close contact with the upper end of the inner side surface of the buried box 1, and the lower surface is hermetically coupled to the projecting portion under the upper end of the inner surface of the buried box 1 A horizontal frame, and a "T" -shaped partition wall that divides the inside of the lid holder 23 into three sections. The vertical frame, the horizontal frame, and the partition may be integrally formed or welded after they are separately manufactured. On the other hand, the "T" -shaped partition wall is prone to warping when a load is loaded on the "T" -shaped partition wall because the three ends are only coupled to the inner surface of the vertical frame. The support base 26 is an H-shaped steel having the same shape as the " T "-shaped partition, and each of the three ends is inserted into the groove of the protruded portion below the upper end of the inner surface of the buried box 1, "Supports the bulkhead of the mold.

A ventilation hole is formed in a horizontal frame of one of the three zones of the lid holder 23, a gasket is formed in the horizontal frame of the other zone, and an entrance is formed in the horizontal frame of the remaining one zone . Hereinafter, the area where the ventilation holes are formed is referred to as an "air conditioning area ", the area where the device is formed is referred to as an " device area ", and the area where the entrance is formed may be referred to as" The appliance compartment of the lid holder 23 is rarely opened except when installing the underground buried container system for the first time and when replacing the built-in appliance 100. [

On the other hand, the air conditioning unit 3 should be frequently replaced as compared with the built-in equipment 100 because the air conditioning performance may decrease in proportion to the use period due to dust and the like. Accordingly, the ventilation hole of the lid holder 23 can be opened more frequently than the machine mechanism. The entrance of the lid holder 23 can be opened more frequently than the appliance mouth and the ventilation port for periodic inspection of the built-in appliance 100, the water cooler 42 and the like. In addition, the manager of the embedded device 100 and the manager of the underground container system shown in FIG. 1 may be different. In this embodiment, as described above, by dividing the inside of the lid holder 23 into three sections, it is possible to take an opening / closing method according to the characteristics of various kinds of openings formed in the lid holder 23 Alternatively, each zone may be managed by a different administrator. For example, a security device such as a lock may be provided on each of the air conditioning upper plate 221 and the out-going upper plate 223 so that they can be managed by different administrators.

That is, since the apparatus holder of the lid holder 23 does not need to be opened except when the underground buried container system is first installed and when the built-in apparatus 100 is replaced, the apparatus upper plate 222 and the apparatus lid 24, Is lifted or lowered by the user. On the other hand, since the ventilation openings and the openings of the lid holder 23 can be opened and closed at any time by the user, the air conditioning upper plate 221, the upper entrance plate 223, and the entrance lid 25, It is not only inconvenient for the user to open and close the door of the lid holder 23 in such a manner that the lid 25 is lifted or lowered, There is a high risk of damage to the components. In order to solve such a problem, in the present embodiment, the user can open / close the ventilating opening and the opening / closing port of the lid holder 23 only by rotating the air conditioning upper plate 221, the upper cover 223 and the lid 25.

The device lid 24 is mounted on the lid holder 23 to cover the lid holder 23 in a sealed state. 1 and 12, the device lid 24 is mounted on a horizontal frame of the appliance space of the lid holder 23 and is sealingly engaged with the horizontal frame of the appliance space of the lid holder 23, In a sealed state. More specifically, the device lid 24 is formed in the shape of a flat plate having the same horizontal plane shape as that of the device section of the lid holder 23, that is, in the shape of a rectangular flat plate, So that the mechanism of the lid holder 23 can be covered in a sealed state. The device lid 24 is separated from the lid holder 23 by the user and moved to another place by the user like the device top plate 222, thereby allowing the built-in device 100 to be exposed.

13 is an assembled view of the device cover 24 shown in Fig. Referring to FIG. 13, a process of assembling the device cover 24 to install the built-in device 100 in the internal space of the buried box 1 is as follows. The built-in apparatus 100 is lowered through the mechanism of the lid holder 23 and placed in the internal space of the embedding box 1. [ Then, the device lid 24 is hermetically coupled to the peripheral surface of the device holder of the lid holder 23. Subsequently, the upper plate 22 and the auxiliary upper plate 224 are mounted on the device lid 24. The built-in apparatus 100 located in the internal space of the buried box 1 needs to be moved to the outside of the underground buried container system for replacement. If the above process is reversed, the embedded device 100 can be moved to the outside of the underground buried container system. That is, the upper plate 22 and the auxiliary upper plate 224 are lifted from the device lid 24 and moved to the outside of the lid holder 23. Then, the device lid 24 is detached from the peripheral surface of the device mouth of the lid holder 23 and moved to the outside of the lid holder 23. Then, the built-in apparatus 100 is lifted through the mechanism of the lid holder 23 and moved to the outside of the underground buried container system.

Nut-shaped grooves are formed at protruding portions of the inner surface of the buried box 1 and holes corresponding to the grooves of the buried box 1 are formed in the device lid 24 and the lid holder 23. The bolts are passed through the holes of the device cover 24 and the lid holder 23 and then fastened to the respective grooves of the buried box 1 so that the lid holder 23 is attached to the protruding portion of the inner side surface of the buried box 1 The device lid 24 can be coupled to the peripheral surface of the device holder of the lid holder 23 at the same time. A waterproofing agent such as silicone is applied to the joining portion of the buried box 1 and the lid holder 23 and the joining portion of the lid holder 23 and the device lid 24 and then the bolts are fastened as described above, 1 and the lid holder 23 can be engaged in a sealed state and the peripheral surface of the device holder of the lid holder 23 and the device lid 24 can be coupled in a sealed state.

The access cover 25 is mounted on the cover holder 23 and covers the entrance of the cover holder 23 in a sealed state. As shown in Figs. 1, 3 and 10, the access cover 25 is mounted on a horizontal frame of the access area of the lid holder 23 and is hermetically engaged with the horizontal frame of the access area of the lid holder 23, 23) in a sealed state. More specifically, the access cover 25 is rotatably coupled to the cover holder 23 in the form of a flat plate, which is the same as the horizontal plane of the device section of the lid holder 23, And the opening and closing of the lid holder 23 is covered or opened in a sealed state. Since the opening and closing of the lid holder 23 is opened and closed by the rotation of the lid 25 as described above, it can not be coupled with the lid holder 23 in a sealed state by the bolt fastening applied to the device lid 24.

The entrance and exit of the lid holder 23 is protruded by a predetermined length so as to be folded upward so that the lid holder 23 and the lid 25 can be sealed by the rotation of the lid 25 And a waterproof band is attached to the bottom surface of the access cover 25 so as to cover the whole protruding portion around the doorway of the cover holder 23. [ The waterproof band can be made of a material having elasticity such as rubber, silicone or the like. When the waterproof band attached to the lower surface of the access cover 25 is pressed by the protruding portion around the entrance of the cover holder 23, the gap between the protruding portion around the entrance of the cover holder 23 and the access cover 25 Lt; / RTI > The upper surface of the lower frame of the access cover 25 and the horizontal frame of the access area of the lid holder 23 can be rotationally coupled by a rotational coupling element such as a hinge or the like. As shown in Figs. 3 and 10, the lower surface of the bottom surface of the door cover 25 and the upper surface of the horizontal frame of the entrance and exit of the lid holder 23 are rotationally coupled by two hinges. The access cover 25 is rotatable by the user around the rotationally coupled element.

The lid 25 has a waterproof band attached to a lower surface of the lid 25 on the lower surface of the lid holder 23 and protruding around the doorway of the lid holder 23, The other side is rotated in the direction of the doorway by the user until it is pressed against the site, so that the entrance of the lid holder 23 can be covered in a sealed state. The lid 25 is rotated in the direction opposite to the direction of the entrance by the user until the waterproof band attached to the lower surface of the lid 25 is separated from the projecting portion around the entrance of the lid holder 23 and stands upright, It is possible to completely open the doorway of the vehicle. 3 and 10, a gas spring for increasing the attractive force of the user acting on the lid 25 to rotate the lid 25 is provided between the lid 25 and the lid holder 23, Can be installed.

The ventilation hole is shielded by the air conditioning part 3 in a state where the joint part between the buried box 1 and the lid holder 23 is sealed and the joint part between the lid holder 23 and the device lid 24 is sealed, When the door is blocked by the cover 25, the internal space of the buried box 1 is sealed. When the internal space of the buried box 1 is sealed, rainwater can not penetrate into the built-in apparatus 100 located in the internal space of the buried box 1 even at the time of rainfall. The ventilating opening of the cover holder 23 is automatically opened and closed in accordance with the inflow amount of the rainwater by the air-conditioning part 3, so that the air-conditioning upper plate 221 does not need to cover the air-conditioning part 3 in a sealed state. As described above, in order to prevent inflow of rainwater into the apparatus mouth and the entrance of the lid holder 23, the apparatus lid 24 must seal the lid of the lid holder 23 in a sealed state, It is necessary to cover the entrance of the lid holder 23.

The air conditioning unit 3 is located in the internal space of the buried box 1 by using the air introduced from the outside of the buried box 1 by ventilating or sealing the internal space of the buried box 1 according to the inflow amount of the rainwater Thereby cooling the built-in device 100. The air conditioning part 3 is mounted on the lid part 2 so as to communicate with at least one ventilating port of the lid part 2 in a sealed state so that the inner space of the embedding box 1 is filled with the inflow amount of the rainwater into the air- Ventilate or seal. Accordingly, it is not necessary to provide a separate space for installing the air conditioning unit 3, so that the size of the underground buried container system having the waterproof function and the cooling function can be minimized. Accordingly, an underground buried container system having a waterproof function and a cooling function can be easily installed in a city where various facilities are buried underground.

1, 3, 5 and 10 - 12, the air conditioning part 3 is mounted on the lid holder 23 so as to communicate with at least one ventilation hole of the lid holder 23 in a sealed state, The inner space of the buried box 1 is ventilated or sealed according to the inflow amount of the rainwater into the rainwater. The air conditioning part 3 is mounted on the horizontal frame of the air conditioning area of the lid holder 23 and is hermetically coupled to the peripheral surface of at least one ventilation hole of the lid holder 23, So that the internal space of the embedding box 1 can be ventilated or sealed according to the inflow amount of the rainwater into the air conditioning part 3. [ The air conditioning part (3) can be made of a hard material which is not rusted by water. For example, the air conditioning part 3 may be made of stainless steel, aluminum alloy, reinforced plastic, or the like.

Particularly, in the present embodiment, the air conditioning part 3 can prevent air from flowing through the at least one ventilation pipe of the air conditioning part 3 according to the inflow amount of the rainwater into the air conditioning part 3, Or airtightly. On the other hand, the air conditioning unit 3 can ventilate or seal the internal space of the buried box 1 according to the inflow amount of the rainwater using one vent pipe. However, when the air circulates between the inside and the outside of the buried box 1 through one ventilation pipe, the flow of air flowing into the ventilation pipe and the flow of air flowing out of the ventilation pipe may collide with each other, The air circulation between the inner space and the outer space may not be smooth. Particularly, the air conditioning part 3 may forcibly circulate air between the inside and the outside of the buried box 1 by using the fan 35 according to the temperature of the internal space of the buried box 1. [

In order to enable forced air circulation between the inner space of the embedding box 1 and the outer space so as to allow air circulation to be smoothly performed, in this embodiment, the outer space of the embedding box 1, The air supply side for allowing air to flow into the internal space and the exhaust side for allowing air to flow out from the internal space of the buried box 1 to the external space of the buried box 1 are separated from each other, The temperature and the humidity of the outside can be kept almost the same as the outside. At least one ventilation hole of the lid holder 23 is connected to the bottom of the submerged box 1 through an air supply mechanism for introducing air from the external space of the submerged box 1 into the internal space of the submerged box 1, And at least one ventilation pipe of the air conditioning part 3 is connected to the outside space of the underfloor box 1 through the air introduced into the internal space of the buried box 1 And an exhaust pipe through which air flows to the external space of the buried box 1 from the internal space of the buried box 1.

14 is an exploded view of the air conditioning unit 3 shown in Fig. 1 and 14, the air conditioning unit 3 includes a housing 31, a filter 32, an air supply unit 33, an exhaust unit 34, and a fan 35. Hereinafter, the assembling process and the connection form between the above-described components will be described with reference to the exploded view shown in FIG. 14 shows only the components provided on the lid holder 23, and the fan 35 provided below the lid holder 23 is omitted. The housing 31 is mounted on the lid holder 23 so as to cover the supply part 33 and the discharge part 34 in the state of a secret rod so as to protect the supply part 33 and the discharge part 34, So that the flow rate of water into the supply part 33 and the discharge part 34 can be controlled. 1, 10 and 12, the housing 31 is mounted on the horizontal frame of the air-conditioning area of the lid holder 23 to cover the supply part 33 and the exhaust part 34 in a state of a secret rod. More specifically, the housing 31 is formed with a plurality of holes on only some of the four side surfaces, the other two side surfaces and the upper surface are sealed, and the lower surface is formed in the shape of an opened rectangular box, 33 and the exhaust part 34 are located in the horizontal frame of the air-conditioning area of the lid holder 23. [

As shown in FIG. 14, a plurality of engagement pieces used for engagement with the lid holder 23 are formed at the lower side of the side surface of the housing 31. In the horizontal frame of the air-conditioning area of the lid holder 23, grooves in the form of a nut are formed, and the engaging pieces of the housing 31 are formed with holes corresponding to the grooves of the horizontal frame of the air- have. The bolts are passed through each of the holes of the coupling pieces of the housing 31 and then fastened to the respective grooves of the horizontal frame of the air-conditioning area of the lid holder 23 so that the housing 31 is fitted to the horizontal frame of the air- Can be combined. A part or the whole of the four sides of the housing 31 is formed in a circular shape so as to be able to be ventilated more smoothly through the housing 31 and to control the inflow speed of water into the air supply part 33 and the exhaust part 34. [ And a plurality of ventilation openings formed on the porous surface. According to the present embodiment, two opposite sides of the four sides of the housing 31 are the porous surfaces.

The filter 32 is attached to the outside or inside of the porous surface of the housing 31 to filter out substances other than air and water from the substances flowing into the air conditioning part 3. The filter 32 is composed of a rectangular filter net in which air and water can be taken in and out, and a rectangular frame in the form of surrounding the filter net. The filter net is press-fitted into the rectangular frame to fix the filter net. The filter net can be made of textile material. Since the housing 31 is generally made of a metal material, it is difficult to process, and often can not be replaced, only to pass air and to form holes through which fine materials such as dust, soil-dripping plants, etc. can not pass. The filter 32 can be prevented from clogging the air conditioning part 3 due to deposition of such fine material by filtering out such fine material, and can be frequently replaced.

Fig. 15 is an exploded view of each of the supply portion 33 and the exhaust portion 34 shown in Fig. 14, Fig. 16 is an internal view of each of the supply portion 33 and the exhaust portion 34 shown in Fig. 14, 17 is a sectional view of each of the supply portion 33 and the exhaust portion 34 shown in Fig. 16 shows the interior of the air supply unit 33 in a direction from the top to the bottom with the air supply duct 331 removed and FIG. 17 shows the center of the air supply duct 331 in the longitudinal direction of the air supply duct 331 And a cross section perpendicular to the crossing line is shown. In this embodiment, since the supply unit 33 and the exhaust unit 34 have the same configuration, they are integrated and shown in one figure. 15, the supply unit 33 includes an air supply duct 331, a piping gasket 332, a gas supply pipe 333, two guide members 334, two sealing packings 335, (336), and two supply pores (337). Hereinafter, an assembling process and a connection form between the above-described components will be described with reference to an exploded view shown in FIG.

The two guide members 334, the two sealing packings 335, the two floats 336 and the two supply pores 337 are arranged such that the supply portion 33 shown in Fig. 14 is above the critical water level (Not shown) to allow air to flow or not to flow through the air supply pipe 333 depending on whether or not it is submerged in water. As will be appreciated from the description below, it will be appreciated that using one guide member 334, one sealing packing 335, one lifting body 336, and one supply pouring tube 337, To allow air to flow or not to flow. However, due to the adoption of a structure for allowing air to flow or not to flow through the air supply pipe 333, the ventilation ability through these elements is lower than the ventilation ability of the air supply pipe 333.

In the present embodiment, two guide members 334, two sealing packings 335, two floating members 336, and two supply pores 337 are provided to maintain the ventilation capability of the air supply pipe 333 Is used. One of ordinary skill in the art will understand that one guide member 334, one sealing packing 335, one floating member 334, A plurality of guide members 334, a sealing packing 335, a floating body 336, and an air supply pore 337 may be used. Can be understood.

The air supply duct 331 is connected between the upper end of the air supply pipe 333 and the upper end of the at least one supply air pipe 337 so that the air supply pipe 333 and the at least one supply air pipe 337 communicate with each other. As shown in FIGS. 15 and 17, the air supply duct 331 is formed in a shape of a rectangular box in which the front side and the front side of the air supply duct 331 are closed and three openings are formed in the lower side, The upper end of one of the air supply pipes 333 is connected to the peripheral surface of the openings and connected to the upper end of the air supply pipe 333 and the upper ends of the two supply air pipes 337 are connected to the peripheral surfaces of the two openings at both ends, Can be connected to the upper ends of the two supply pores 337 by being coupled one by one. 15, the air supply duct 331 is constituted by a duct top plate 3311, a duct gasket 3312, and a duct bottom plate 3313.

The duct upper plate 3311 is sealed in the front side and the upper side in the forward direction, and the lower side is coupled to the lower duct plate 3313 in the shape of an opened rectangular box. The duct gasket 3312 is inserted between the duct upper plate 3311 and the lower duct plate 3313 in the form of a square frame having four straight frames connected at right angles to seal the gap between the duct upper plate 3311 and the lower duct plate 3313 . The lower duct plate 3313 is formed in a rectangular plate shape in which three circular openings are arranged in the longitudinal direction, the upper surface of which is coupled to the lower end of the duct top plate 3311, and one circular opening And the upper ends of the two supply pores 337 are brought into close contact with the circumferential surfaces of the two circular openings at both ends.

A coupling piece extending from the lower end of the duct upper plate 3311 to the outside and bent to a predetermined length is formed around the lower end of the duct upper plate 3311. 15-17, a plurality of holes are formed at positions corresponding to each other in the coupling piece of the duct top plate 3311, the duct gasket 3312, and the duct bottom plate 3313. [ The bolts are sequentially passed through the holes of the coupling piece of the duct upper plate 3311 and the duct gasket 3312 and the holes of the lower duct plate 3313 and then fastened with the nuts so that the duct upper plate 3311, the duct gasket 3312, The lower plate 3313 can be engaged. Accordingly, the duct upper plate 3311 and the duct lower plate 3313 can be coupled in a sealed state with a gap therebetween.

Since the upper end of the air supply duct 333 is sealed and the upper ends of the two air supply pores 337 are coupled to the three openings of the lower surface of the air supply duct 331 having the rectangular box shape, The rainwater falling into the air conditioning part 3 shown in FIG. 17 can not flow into the direct air supply line 333 but flows into the airtight upper surface of the air supply duct 331 and flows thereafter, Or directly into the holes in the lower portion of each supply pore 337. As shown in Figs. 15-17, the upper part of each supply pore 337 is covered by the supply air duct 331, so that the rainwater can not flow into the holes in the upper part of each supply pore 337. Therefore, in order for the rainwater to flow into the air supply duct 333, the rainwater flows into the lower holes of the air supply pores 337, passes through the connection portion between the air supply pores 337 and the air supply duct 331, It must pass through the inner space of the duct 331. Since the inner space of the air supply duct 331 is positioned higher than the lower portion of each supply air pipe 337, the rainwater flowing into the lower holes of the air supply pores 337 flows into the inner space of the air supply duct 331 . As a result, the rainwater falling down to the air conditioning unit 3 shown in Figs. 15-17 is hardly introduced into the air supply duct 333.

The piping gasket 332 is inserted between the peripheral surface of the central opening of the air supply duct 331 and the upper end of the air supply duct 333 in the shape of a rectangular plate having a circular opening at the center thereof, And seals the gap between the circumferential surface of the central opening and the upper end of the air supply pipe 333. As shown in Figs. 1 and 3, a plurality of holes are formed around the opening of the piping gasket 332. Correspondingly, a coupling piece having the same shape as that of the piping gasket 332, which is bent at right angles to the outside from the upper end of the air supply pipe 333, is formed around the upper end of the air supply pipe 333. A plurality of holes are formed at positions corresponding to each other in the upper coupling piece of the air supply duct 331, the piping gasket 332, and the air supply pipe 333. The bolts are successively passed through the holes of the upper end coupling holes of the air supply duct 331 and the piping gasket 332 and the upper end coupling holes of the air supply pipe 333 and then tightened with the nuts to supply the air supply duct 331 and the piping gasket 332, The upper engagement piece of the engine 333 can be engaged. Accordingly, the air supply duct 331 and the air supply tube 333 can be coupled in a sealed state with a gap therebetween.

The upper end of the air supply duct 333 is hermetically coupled to the circumferential surface of the center opening of the three outlets of the air supply duct 331 from the upper side to the upper side of the lid holder 23 to communicate with the inner space of the air supply duct 331 And the lower end thereof is hermetically coupled to the circumferential surface of the air supply mechanism of the lid holder 23 to communicate with the inner space of the embedding box 1. [ As shown in FIGS. 15 and 17, the air supply duct 333 is closed at its side in the front direction and the upper and lower surfaces are opened in a cylindrical shape. The upper end of the air supply duct 333 is provided with a pipe gasket 332 So that the lower end thereof is welded to the circumferential surface of the air supply mechanism of the lid holder 23 so that the air supply duct of the air supply duct 331 is sealed Can be combined. It is difficult for the air supply tube 333 to separate from the lid holder 23 when the lower end of the air supply tube 333 is welded and joined to the circumferential surface of the air supply mechanism of the lid holder 23. In this embodiment, the air conditioning unit 3 can be replaced by replacing the remaining components except for the air supply unit 333.

Each of the two guide members 334 is provided at the upper end of each supply pore 337 and has a passage through which the protruding rods of the respective floating bodies 336 can be inserted and slid while the air is being passed, 336 in the vertical direction. That is, the left guide member 334 is provided on the upper side of the left air supply pouring tube 337, and has a passage through which the protruding rod of the left-side floating body 336 can be inserted and slid while the air passes, 336 in the vertical direction. Likewise, the right guide member 334 is provided at the upper end of the right air supply pail 337, and has a passage through which the protruding bar of the right side lifting body 336 can be inserted and slid while the air passes, 336 in the vertical direction.

Since each of the floating bodies 336 is inserted into the passage of the guide member 334 and slidably moved, the floating bodies 336 are introduced into the respective supply pores 337 without shaking in the respective supply pores 337 It can be moved up and down in proportion to the amount of rainwater. As a result, it is possible to prevent the sealing of the connection portion between the supply air duct 331 and the air supply duct 331 at the normal time, thereby maximizing the period during which the internal space of the installation box 1 is ventilated with the outside. It is possible to prevent the openings of the connecting portions between the supply air pipes 337 and the air supply duct 331 from being opened, and the inflow of rainwater into the inner space of the buried box 1 can be surely blocked.

As shown in Figs. 15-17, each of the guide members 334 has a circular plate shape in which an upper surface of the guide member 334 is hermetically coupled to the circumferential surface of each of the openings at both ends of the air supply duct 331, and a cylindrical- And an inner frame of a cross spoke shape in which the outer frame of the outer frame and the inner surface of the ventilation passage of the outer frame are integrally connected with each other and a cylindrical guide passage is formed at the center thereof. The upper surfaces of the guide members 334 are welded to the respective circumferential surfaces of the openings of the opposite ends of the air supply duct 331 so as to be hermetically coupled to the respective circumferential surfaces of the openings of the opposite ends of the air supply duct 331. As described above, each guide member 334 allows the air to pass through the triangular columnar passages formed by dividing the inside of the cylindrical ventilation passage of the outer frame by the cross-spoke shape of the inner frame, Guides the lifting members 336 up and down by causing the protruding rods of the respective lifting members 336 to slide on the inner surface of the guide passage formed at the center of the inner frame inside.

Each of the two sealing packings 335 is in the form of a disk having a circular opening at the center thereof, and the upper surface thereof is hermetically coupled to the lower surface of each guide member 334. That is, the upper surface of the left seal packing 335 is coupled to the lower surface of the left guide member 334, and the upper surface of the right seal packing 335 is coupled to the lower surface of the left guide member 334. Each of the sealing packings 335 may be made of a waterproof material having elasticity such as rubber and is adhered to the lower surface of each guide member 334 by using a waterproof adhesive so that the lower surface of each guide member 334 is sealed Lt; / RTI >

When the periphery of the hole of the sealing material 335 of the rubber material is pressed by the outer surface of the spherical shape of the floating body 336, the hole of the sealing packing 335 is sealed. Therefore, the waterproof ability of the seal packing 335 is determined by the force that the lifting body 336 presses the seal packing 335. Since the force by which the lifting body 336 presses the seal packing 335 is determined by the buoyancy acting on the lifting body 336 by the water inside the supply pore 337, It is preferable to have the maximum diameter in a state in which it can be moved up and down without friction with the inner surface of the porous tube 337.

Each of the two floating bodies 336 is located in the inner space of each supply pore 337 and is connected to the inner space of each supply pore 337 in accordance with the amount of rainwater flowing through the holes of each supply pore 337 As shown in FIG. That is, the left levitated body 336 is located in the inner space of the left supply pouring tube 337 and is connected to the inner space of the left supply pouring tube 337 according to the amount of the rainwater flowing through the holes of the left supply pouring tube 337 As shown in FIG. Similarly, the right lifting body 336 is located in the inner space of the right air supply pore 337 and is located in the inner space of the right air supply pore 337 in accordance with the amount of water flowing through the holes of the right air supply pore 337 Move up and down. As shown in FIGS. 15-17, each of the floating bodies 336 may be a spherical ball having a weight smaller than the buoyancy caused by water and having a protruding rod formed on one side thereof. The floating body 336 is preferably made of a material having a specific gravity smaller than that of water so as to float on the rainwater. For example, the floating body 336 may be made of plastic, styrofoam, rubber, or the like. The interior of the levitated body 336 may be empty to make the weight of the levitated body 336 lighter.

Each of the two supply pores 337 is in close contact with the circumferential surface of each of the openings at both ends of the lower end of the air supply duct 331 and the lower end is in close contact with the horizontal frame of the air- And is installed upright on the horizontal frame of the air-conditioning area of the lid holder 23. The upper end of the left air supply poured pipe 337 is in close contact with the peripheral surface of the left end opening of the lower surface of the air supply duct 331 and the lower end of the left air supply pore 337 is in close contact with the horizontal frame of the air conditioning area of the lid holder 23, And is installed upright on the horizontal frame of the air-conditioning area of the lid holder 23. Likewise, the right air supply pouring tube 337 is in close contact with the circumferential surface of the right end opening of the lower surface of the air supply duct 331 at the upper end and the lower end is brought into close contact with the horizontal frame of the air conditioning space of the lid holder 23, And is installed upright on the horizontal frame of the air-conditioning area of the lid holder 23.

Since the supply pores 337 are not required to be watertight, the upper and lower ends of the supply pores 337 do not need to be sealedly coupled to the supply duct 331 and the lid holder 23. There may be a certain gap between the upper end of the air supply pore 337 and the air supply duct 331 and between the lower end of the air supply pore 337 and the horizontal frame of the air conditioning area of the lid holder 23, There may be a gap of degree. In the present embodiment, the air supply pore 337 guides the lifting body 336 together with the guide member 334 so that the lifting body 336 can move up and down without shaking, and receives the rainwater falling on the air conditioning unit 3 shown in Fig. And a buoyancy force is applied to the body 336 at the same time. The structure of the air conditioning part 3 is very simple and can be easily separated from the object by employing the air supply pouring tube 337, so that the air conditioning part 3 can be easily replaced, repaired, and managed.

15-17, each of the supply pores 337 is formed with a plurality of holes on its side in the forward direction, and the upper and lower surfaces thereof are formed into an open cylindrical shape and are provided with openings at both ends of the lower surface of the air supply duct 331 And the upper end of the guide member 334 is fitted around the lower side surface of the guide member 334 so that the upper end is inserted into the circumferential surface of the lower end of the lower end of the air supply duct 331 The bottom end of the lid holder 23 is in close contact with the horizontal frame of the air conditioning space of the lid holder 23 and as a result it can be installed upright on the horizontal frame of the air conditioning space of the lid holder 23 in parallel with the air supply port 333.

Fig. 18 is a view showing the operation of ventilating the internal space of the buried box 1 shown in Fig. 15, and Fig. 19 is a view showing the operation of the air conditioning part 3 shown in Fig. In Fig. 1). Fig. Referring to Figs. 18-19, the connection portions between the supply air pores 337 and the air supply duct 331 are opened by the up-and-down movement of the floating bodies 336 in the inner space of the supply air pores 337 Air is introduced into the internal space of the buried box 1 from the outside through the air supply port 333 or the inflow of such air is blocked. That is, the connection portion between the left air supply pail 337 and the air supply duct 331 is opened or sealed by the up-and-down movement of the left-side floating body 336 in the inner space of the left air supply pore 337. Similarly, the connection portion between the right air supply pail 337 and the air supply duct 331 is opened or sealed by the up-and-down movement of the right side lifting body 336 in the inner space of the right air supply pore 337.

Each supply pore 337 and the air supply duct 331 are provided with a guide member 334 which is hermetically coupled to the circumferential surfaces of the openings at both ends of the air supply duct 331, When the holes of each sealing packing 335 are opened or sealed, the connection portions of the supply air pores 337 and the air supply ducts 331 are opened or sealed. 18-19, both the connecting portion of the left air supply pail 337 and the air supply duct 331 and the connection portion of the right air supply pail 337 and the air supply duct 331 must be sealed, 333 may be blocked, and if any one of them is opened, air may be introduced through the air supply port 333.

18, each lifting body 336 is lowered in the inner space of each supply pore 337, and between the periphery of the hole of each sealing packing 335 and the outer surface of the spherical shape of each lifting body 336 The connecting space between each supply pore 337 and the supply duct 331 is opened so that the inner space of the buried box 1 can be vented to the outside through the air supply pipe 333. [ Since the lifting body 336 rises in proportion to the height of the water introduced through the holes of the supply pores 337, there is no water in each supply pores 337 or the holes of the supply pores 337 An empty space is formed between the outer surface of the spherical surface of each lifting body 336 and the periphery of the hole of each sealing packing 335 until the water supply pipe 337 is immersed in the water below the threshold water level So that the connection sites of the supply air pipes 337 and the air supply ducts 331 are opened.

That is, until there is no water in the left air supply pore 337 or water is poured into the holes of the left air supply pore 337 and the left air supply pore 337 is submerged in the water below the critical water level, An empty space is formed between the outer surface of the spherical body 336 and the periphery of the hole of the left sealing packing 335 so that the connection portion between the left air supply pouring tube 337 and the air supply duct 331 is opened. Likewise, until there is no water inside the right air supply pore 337 or water is introduced into the holes of the right air supply pore 337 and the right air supply pore 337 is immersed in water below the critical water level, An empty space is formed between the outer surface of the sphere 336 and the periphery of the hole of the right seal packing 335 so that the connection portion between the right air supply pore 337 and the air supply duct 331 is opened.

19, each lifting body 336 rises in the inner space of each supply pore 337 and the perimeter of the hole of each sealing packing 335 is located on the outer surface of the spherical surface of each lifting body 336 The connecting portion between the supply air supply pipe 337 and the air supply duct 331 is sealed and air can not be introduced through the air supply pipe 333. When water is introduced into the holes of each supply pore 337 and each supply pore 337 is immersed in water having a height exceeding the critical water level, the spherical outer surface of each of the floats 336 is sealed by the seal packing 335, The respective lifting members 336 rise in the inner space of each supply pouring tube 337 until the peripheral portion of the supply pouring pipe 337 and the supply air duct 331 are pressed against each other, .

That is, when the left supply pouring tube 337 is immersed in water of a height exceeding the critical water level, the left side floating body 336 is lifted by a height proportional to the level of the water introduced through the holes of the left air supply pore 337 The outer surface of the spherical shape pushes the periphery of the hole of the left seal packing 335 so that the connection portion between the left air supply pore 337 and the air supply duct 331 is sealed. Likewise, when the right supply pore 337 is immersed in water at a height exceeding the critical water level, the right side pouring 337 is lifted by a height proportional to the height of the water introduced through the holes of the right air supply pore 337 The outer surface of the spherical shape presses the periphery of the hole of the right seal packing 335 so that the connection portion between the right air supply pore 337 and the air supply duct 331 is sealed.

After each supply pore 337 is immersed in water at a height exceeding the critical water level, water is discharged from the pores of each supply pore 337 so that each supply pore 337 is immersed in water below the critical water level Each lifting body 336 is lowered away from the periphery of the hole of the sealing packing 335 so that a gap is formed between the outer surface of the spherical shape of each lifting body 336 and the periphery of the hole of each sealing packing 335 A space is formed so that a connection site between each supply pore 337 and the air supply duct 331 is opened. As described below, the exhaust portion 34 also operates in the same manner as the operation of this supply portion 33. Therefore, the air conditioning part 3 shown in Fig. 14 can seal the internal space of the buried box 1 only during the rain, and ventilate the internal space of the buried box 1 normally. With the air conditioning unit 3, the internal space of the buried box 1 is waterproof, and temperature, humidity, and the like can be automatically maintained in a state similar to the outside through ventilation with the outside.

That is, the air conditioning unit 3 according to the present embodiment normally ventilates the inner space of the buried box 1 to cool the equipment installed in the inner space of the buried box 1 by natural convection, When water is introduced into the air conditioning part 3 due to the air conditioning function and the rainfall or the like, the inner space of the buried box 1 is sealed so that the immersion of the equipment installed in the inner space of the buried box 1 Waterproofing function. As described above, the air conditioning unit 3 according to the present embodiment has a waterproof function in addition to the air conditioning function, so that air conditioning and waterproofing of the internal space of the object can be performed at a very low cost without installing separate ground facilities for waterproofing the object Lt; / RTI > For example, if the electric equipment is installed in the internal space of the buried box 1, the failure rate of the electric equipment due to the overheat and the excessive humidity can be greatly reduced, and the electric equipment can be operated in the optimal condition. .

As described above, if any one of the connecting portion between the left air supply pail 337 and the air supply duct 331 and the connection portion between the right air supply pail 337 and the air supply duct 331 are opened, The air can be introduced into the inner space of the housing. Therefore, in order to block the inflow of air through the air supply duct 333, both the connection portion between the left air supply pore 337 and the air supply duct 331 and the connection portion between the right air supply pores 337 and the air supply duct 331 It must be sealed. On the other hand, when the left supply pouring tube 337 and the right supplying pouring tube 337 are installed on a horizontal plane, the left supply pouring tube 337 and the right supplying pouring tube 337 are immersed in water of the same height, The connecting portion between the left air supply pouring tube 337 and the air supply duct 331 and the connection portion between the right air supply pouring tube 337 and the air supply duct 331 are simultaneously opened or sealed. Therefore, in order to more precisely control the sealing of the connecting portion between the left air supply pail 337 and the air supply duct 331 and the connection portion between the right air supply pail 337 and the air supply duct 331, the left air supply pail 337, And the right supply pouring tube 337 are provided on the horizontal plane.

According to the present embodiment, the spherical outer surface of each lifting body 336 presses the peripheries of the holes of the respective seal packing 335 provided at the connection portion between the supply pail 337 and the supply duct 331, Since the connecting portions of the porous pipe 337 and the air supply duct 331 are sealed so that the respective lifting bodies 336 are raised to less than half the diameter of the respective lifting bodies 336, The hole is sealed. However, when the sizes of the floating bodies 336 are small, each floating body 336 can be instantaneously immersed in water rapidly flowing through the holes of the supply pores 337. If the floating bodies 336 are immersed in rainwater, the rainwater may flow into the air supply pipes 333. As the size of each of the floating bodies 336 increases, the possibility that each floating body 336 is immersed in the water flowing into the holes of each supply pore 337 becomes increasingly scarce.

In this embodiment, each lifting body 336 has a diameter larger than the maximum diameter that can be submerged in the water flowing into the holes of each supply pore 337 at the maximum flow rate. Therefore, even if water flows into the holes of the supply pores 337 at the maximum flow rate, each of the floating bodies 336 can not be immersed in the water inside each supply pores 337. Here, the maximum flow velocity of water flowing through the holes of each supply pore 337 is the same as the maximum flow velocity of the holes of each supply pore 337 due to the rainfall at the place where the air conditioning part 3 shown in Figs. 15-17 is installed Which means the maximum flow rate of the rainwater flowing through. As described above, it is preferable that each lifting body 336 has a maximum diameter in a state in which the lifting body 336 can be moved up and down without friction with the inner surface of each supply pouring tube 337. That is, the diameter of each levitated member 336 is close to the inner diameter of each supply pore 337.

Not only the hole of the sealing packing 335 is sealed while the diameter of the floating body 336 is raised to less than half the diameter of the floating body 336 and the diameter of the floating body 336 is close to the inner diameter of the supply pore 337, The height of the water introduced into the supply pore 337 until the hole of the packing 335 is sealed is raised to less than half the diameter of the lifting body 336 and the height of the water introduced into the supply pore 337 The water is obstructed by the half of the diameter of the floating body 336 having the diameter close to the inner diameter of the supply pore 337, that is, the widest portion. As a result, the possibility of water flowing from the holes in the upper portion of the air supply pouring tube 337 located at a height equal to or more than 1/2 of the diameter of the floating body 336 disappears. In addition, since the internal space of the air supply duct 331 is located higher than the lower portion of each supply air pipe 337, the inflow of rainwater into the air supply pipe 333 is completely blocked.

When the holes of each supply pore 337 are large, water flows into each supply pore 337 at a high speed. As soon as the rain starts to come down, the float 336 rises and flows into the supply pores 337 The connection portion of the air supply duct 331 can be sealed immediately. However, when the size of the floating body 336 is too small compared to the size of the holes of the supply air pneumatic pipes 337, the floating body 336 is pushed into the water introduced into each supply pouring tube 337 There is a possibility that water may flow into the engine 333. On the other hand, when the pores of the supply pores 337 are small, the water slowly flows into the supply pores 337, so that the floating body 336 is inserted into the water flowing into each supply pores 337, The probability of being locked is reduced. However, when the size of the hole of each supply pore 337 is excessively small as compared with the size of the floating body 336, the floating body 336 slowly rises, and after a certain period of time has elapsed after the start of the rain, Since the connection portion between the supply pore 337 and the supply air duct 331 is sealed, the reactivity of sealing of the connection portion between the supply air pores 337 and the supply air duct 331 may be deteriorated. The reactivity of the sealing of the connection portion between each supply pore 337 and the supply air duct 331 and the risk of flooding the floating body 336 are bridged so that the holes of each supply pore 337 are designed to have an optimum size desirable.

15, exhaust unit 34 includes exhaust duct 341, piping gasket 342, exhaust pipe 343, two guide members 344, two sealing packings 345, two floating bodies 342, 346, and two exhaust perforated pipes 347. Two gas-permeable pipes 331, 332, 333, two guide members 334, two sealing packings 335, two floating bodies 336, and two supply pores 337 Is provided with an exhaust duct 341, a piping gasket 342, an exhaust pipe 343, two guide members 344, two sealing packings 345, two floats 346, The two exhaust pores 347 perform an exhaust operation. Since the configurations of the two embodiments are the same except for these differences, only the basic configuration related to the exhaust operation will be described below, and the remaining configuration will be replaced with the description as described above with reference to Figs. 15-17.

The exhaust duct 341 is connected between the upper end of the exhaust pipe 343 and the upper end of the two exhaust perforated pipes 347 so that the exhaust pipe 343 and the two exhaust perforated pipes 347 communicate with each other. Referring to Fig. 15, the exhaust duct 341 is composed of a duct top plate 3411, a duct gasket 3412, and a duct bottom plate 3413. The pipe gasket 342 is inserted between the peripheral surface of the central opening of the exhaust duct 341 and the upper end of the exhaust pipe 343 in the shape of a rectangular plate having a circular opening at the center thereof, Thereby sealing the gap between the circumferential surface of the opening and the upper end of the exhaust pipe 343. The exhaust pipe 343 is hermetically connected to the circumferential surface of the center opening of the three openings of the exhaust duct 341 from the upper side to the upper side of the lid holder 23 to communicate with the inner space of the exhaust duct 341, And the lower end is hermetically connected to the circumferential surface of the vent hole of the lid holder 23 to communicate with the inner space of the embedding box 1. [

Each of the two guide members 344 is provided at the upper end of each exhaust pore 347 and has a passageway through which the protruding rods of the respective floating bodies 346 can be inserted and slid while the air passes therethrough, 346 in the vertical direction. Each of the two sealing packings 345 is in the form of a disk having a circular opening formed at the center thereof, and the upper surface thereof is coupled to the lower surface of each guide member 344. When the perimeter of the hole of each seal packing 345 is pressed by the outer surface of the spherical surface of each of the floating bodies 346, the hole of each seal packing 345 is sealed. Each of the two floating bodies 346 is located in the inner space of each exhaust pore 347 and is positioned in the inner space of each exhaust pore 347 in accordance with the amount of water flowing through the holes of each exhaust pore 347 Move up and down. Each of the two exhaust pores 347 has an upper end which is in close contact with the circumferential surface of each of the openings at both ends of the lower surface of the exhaust duct 341 and a lower end which is in close contact with the horizontal frame of the air- And is installed upright on the horizontal frame of the air-conditioning area of the lid holder 23 in parallel.

The connection portions of the exhaust pores 347 and the exhaust duct 341 are opened or sealed by the vertical movement of the floating bodies 346 in the internal space of the exhaust pores 347, The air flows out from the internal space of the buried box 1 through the outside or the outflow of such air is blocked. That is, each of the floating bodies 346 is lowered in the inner space of each exhaust pore 347, thereby forming an empty space between the periphery of the hole of each sealing packing 345 and the outer surface of the spherical shape of each floating body 346 The connection portion between the exhaust pipe 347 and the exhaust duct 341 is opened and air flows out to the inner space of the buried box 1 through the exhaust pipe 343. [ When the floating bodies 346 rise in the inner space of each exhaust pore 347 and the peripheries of the holes of the respective seal packing 345 are pressed by the spherical outer surfaces of the respective floating bodies 346, The connection portion between the exhaust duct 341 and the exhaust duct 341 is sealed so that the outflow of air through the exhaust pipe 343 is blocked.

The connecting portions of the left exhaust pores 347 and the exhaust duct 341 and the connecting portions of the right exhaust pores 347 and the exhaust duct 341 must be sealed before the exhaust pipe 343 The air can be blown out through the exhaust pipe 343 if any one of them is opened. As shown in FIGS. 1 and 14, the connecting portion between the left air supply pore 337 and the air supply duct 331 of the air supply portion 33 and the connection portion between the right air supply pore 337 and the air supply duct 331 Both the connecting portion between the left exhaust pore 347 and the exhaust duct 341 of the exhaust portion 34 and the connection portion between the right exhaust pore 347 and the exhaust duct 341 must be sealed, The space can be sealed, and if any one of them is opened, the inner space of the buried box 1 can be ventilated.

The cooling unit 4 cools the built-in appliance 100 using the cooling water introduced from the outside of the buried box 1 through the piping installed inside and outside the buried box 1 under the control of the control unit 5 . Referring to Fig. 1, the cooling section 4 is composed of a water tank 41, a water cooler 42, and a pipe 43. The water tank 41 is located outside the buried box 1 and stores therein water that is cooled by the temperature difference between the inside and the outside of the buried box 1. The water tank 41 may be installed in close contact with one side of the four sides of the buried box 1 in the shape of a rectangular box sealed in its entirety. The buried box 1 is formed with a projecting portion having a constant width for supporting the water tank 41 which is in contact with one side of the buried box 1 at a predetermined height around the side surface of the buried box 1. Since the water tank 41 is buried in the underground together with the buried box 1, it is supported by the protrusions on the side surface of the buried box 1 and surrounding rubble, gravel and the like and is in close contact with one side surface of the buried box 1 Can be fixed.

At least one gap is formed in the buried box 1 so that the rainwater flowing into the lid 2 flows out to the outside of the buried box 1 in order to cool the water stored in the water tank 41. [ For example, as shown in Figs. 6-11, each of the four side surfaces of the buried box 1 is provided with a gap through which the rainwater flowing into the lid 2 flows out. As described above, the lid holder 23 is closely inserted into the upper end of the inner side surface of the buried box 1 and is seated in a sealed state at the projecting portion below the upper end of the inner side surface of the buried box 1. A gap is formed in the bottom edge of the lid holder 23 which is hermetically sealed to the protruding portion under the upper end of the inner side surface of the buried box 1 so as to allow the rainwater flowing into the lid 2 to flow out. A gap is also formed in the portion of the embedding box 1 which abuts against the clearance of the lid holder 23 in correspondence thereto. The rainwater flowing into the lid portion 2 passes through the clearance of the lid holder 23 and the clearance between the buried box 1 and is discharged to the outside of the buried box 1. [

The outer surface of the water tank 41 is cooled by the rainwater flowing out through the clearance of the buried box 1 which is in contact with the clearance of the lid holder 23 and is cooled by the cooling of the outer surface of the water tank 41 41 are cooled and supplied to the water cooler 42 through the water supply pipe 431. The rainwater flowing through the surface of the ground can flow through the rubble around the water tank 41 during rainfall. Therefore, the outer surface of the water tank may be cooled by the rainwater flowing into the rubble around the water tank 41, the gravel, etc., in addition to the rainwater flowing out through the clearance of the buried box 1. It is preferable to increase the contact area between the water stored in the water tank 41 and the outer surface of the water tank 41 as much as possible in order to improve the cooling efficiency of the water stored in the water tank 41. Accordingly, the inside of the water tank 41 can be formed in the shape of a twisted pipe in various forms.

The water cooler 42 is located in the internal space of the buried box 1 under the control of the control unit 5 and uses the water introduced from the water tank 41 as cooling water to cool the built- 100). As described above, by using the water introduced from the water tank 41 located outside the buried box 1 as cooling water, the consumption of electric energy due to the cooling of the built-in appliance 100 can be reduced. More specifically, the water cooler 42 compresses the refrigerant and condenses the refrigerant compressed with the water introduced from the water tank 41 to condense the condensed refrigerant in the indoor unit 100 And cooled. For example, the water cooler 42 can cool the built-in appliance 100 by absorbing the heat of the internal space of the buried box 1. R-22 may be used as the refrigerant, and other materials may be used. The water-cooling system according to the present embodiment is characterized in that the built-in appliance 100 is cooled by using the water in the water tank 41 provided on one side of the buried box 1. [ Meanwhile, since the cooling method according to the compression, condensation, and vaporization of the refrigerant is well known to those skilled in the art, a detailed description thereof will be omitted.

The pipe 43 is connected between the water tank 41 and the water cooler 42 to circulate water between the water tank 41 and the water cooler 42. Referring to FIG. 1, the pipe 43 is composed of a water supply pipe 431 and a drain pipe 432. The water supply pipe 431 is connected between the water tank 41 and the water cooler 42 to supply the water stored in the water tank 41 to the water cooler 42. The water supply pipe 431 may be connected between the water tank 41 and the water cooler 42 by having one end sealed in the water tank 41 and the other end sealingly coupled to the water cooler 42. The water discharge pipe 432 is connected between the water tank 41 and the water cooler 42 to supply the water discharged from the water cooler 42 to the water tank 41. The water pipe 432 may be connected between the water tank 41 and the water cooler 42 by one end being hermetically coupled to the water tank 41 and the other end being hermetically coupled to the water cooler 42. 1, 10, and 11, a sealing member 44 for allowing the water supply pipe 431 and the drain pipe 432 to pass through the lower side wall of the buried box 1 in a sealed state is provided in the buried box 1, And is press-fitted into the lower side wall.

The control unit 5 controls the driving of at least one of the air conditioning unit 3 and the cooling unit 4 according to at least one of whether the inner space of the buried box 1 is sealed and the temperature. The control unit 5 may be implemented as a microcomputer. More specifically, the control unit 5 stops the operation of the air conditioning unit 3 according to whether the internal space of the buried box 1 is sealed or not, thereby stopping the operation of the air conditioning unit 3 between the internal space of the buried box 1 and the external space of the buried box 1. [ The indoor unit 100 is cooled by the natural convection generated due to the temperature difference or the forced air circulation between the inner space of the embedding box 1 and the outer space of the embedding box 1 by driving the air conditioning unit 3 So that the built-in apparatus 100 can be cooled. The control unit 5 stops the operation of the fan 35 of the air conditioning unit 3 according to the temperature of the internal space of the buried box 1 so that the internal space of the buried box 1 and the outside of the buried box 1 The internal space of the buried box 1 and the buried box 1 are cooled by cooling the built-in apparatus 100 by natural convection generated due to the temperature difference between the spaces or by driving the fan 35 of the air- The internal apparatus 100 may be cooled by forced air circulation between the external space of the refrigerating apparatus 100 and the cooling unit 4 may be driven so that the internal apparatus 100 is cooled by heat absorption during the evaporation of the refrigerant.

The air conditioning unit 3 according to the present embodiment is provided with the fan 35 and the proximity sensors 338 and 348 in the components of the air conditioning unit 3 described above for forced air circulation in the internal space of the buried box 1 . As shown in Fig. 15, the proximity sensors 338 and 348 are installed inside the air conditioning unit 3 shown in Fig. As shown in Fig. 1, the fan 35 is installed in the horizontal frame of the air-conditioning area of the lid holder 23 from below the lid holder 23. On the other hand, in order to cool the internal space of the buried box 1 intermittently in accordance with the temperature of the internal space of the buried box 1, a temperature sensor is installed in the internal space of the buried box 1. The proximity sensor 70 is provided on the upper side of each of the porous pipes 337 and 347 and detects the proximity between this and the respective floating bodies 336 and 346. The temperature sensor detects the temperature of the internal space of the buried box 1. The temperature sensor is not an element having any technical feature in its outline or internal structure and is omitted from FIG. 1 in order to avoid complication of the drawing because the present embodiment can be understood only by the description thereof.

The fan 35 is connected to the circumferential surface of the feed mechanism of the lid holder 23 at the lower side of the lid holder 23 under the control of the control unit 5 and is connected to the outside of the lid box 1 via the feed tube 333 Air is sucked and is coupled to the circumferential surface of the exhaust port of the lid holder 23 at the lower side of the lid holder 23 and exhausts air to the outside of the buried box 1 through the exhaust pipe 343, So that the sucked air is forcibly circulated in the inner space of the buried box 1 and discharged through the exhaust pipe 343. [ The inner space of the buried box 1 is sealed by the air supply part 3 and the exhaust part 4 during the rainfall so that the fan 35 is hermetically connected to the peripheral surface of the air supply mechanism of the lid holder 23 There is no need. However, since the efficiency of the fan 35 decreases as the distance between the periphery of the supply mechanism of the fan 35 and the supply mechanism of the lid holder 23 decreases, the fan 35 and the periphery of the supply mechanism of the lid holder 23 Preferably, the surfaces are bonded as closely as possible.

1, the fan 35 is composed of an air supply fan 351, an air discharge fan 352, and a fan case 353. The air supply fan 351 is connected to the circumferential surface of the air supply mechanism of the lid holder 23 from the lower side of the lid holder 23 in a sealed state or in a secret rod state, The air is sucked from the outside of the embedding box 1 through the air supply duct 333 to the inner space of the embedding box 1. The air supply fan 351 may be hermetically coupled to the circumferential surface of the air supply mechanism of the lid holder 23 in order to improve its efficiency. The exhaust fan 352 is connected to the periphery of the exhaust port of the lid holder 23 at the lower side of the lid holder 23 in a secret rod state and is connected to the buried box 331 by a blade rotating in a direction to discharge air to the exhaust pipe 343. [ 1 and discharges the air to the outside of the buried box 1 through the exhaust pipe 343. [ The fan case 353 is coupled to the inner surface of the object 100 in a state where the air supply fan 351 and the air discharge fan 352 are accommodated and the fans 351 and 352 are connected to the peripheral surface of the air supply mechanism of the lid holder 23 And the peripheral surface of the exhaust port of the lid holder 23.

As described below, the driving of the air supply fan 351 and the exhaust fan 352 is stopped under the control of the control unit 5 at the time of rainfall. The air supply fan 351 and the exhaust fan 352 can be driven even in the event of rain due to various causes such as failure of the control unit 5. [ The driving of the air supply fan 351 acts in the direction of lifting up the floating body 336 from the inside of the air supply pore 337. Therefore, even if the air supply fan 351 is abnormally driven, the motor temperature of the air supply fan 351 rises, There is no problem other than unnecessary power consumption. In addition, since the driving of the exhaust fan 352 operates in a direction to lower the floating body 346 in the air supply pore 337, if the exhaust fan 352 is driven abnormally, The problem that the spherical outer surface of the floating body 346 and the perimeter of the hole of the sealing packing 345 spreads and the rainwater flows into the hole of the sealing packing 345 Lt; / RTI >

A smaller wind force than the buoyancy of each of the levitation bodies 346 generated by the water introduced through the holes of each exhaust pore 347 acts on each levitated body 346 located in the interior space of each exhaust pore 347 A gap may be formed between the circumferential surface of the exhaust port of the exhaust fan 352 and the lid holder 23. As such, less wind force than the buoyancy of each levitated body 346 generated by the water introduced through the holes in each exhaust pore 347 is directed to each of the levitations 346 located in the interior space of each exhaust pore 347 Even if the exhaust fan 352 is driven in a state in which the spherical outer surface of each of the floating bodies 346 presses around the hole of each seal packing 345, (352) and the circumferential surface of the exhaust port of the lid holder (23). That is, each of the floating bodies 346 is not lowered by the driving of the exhaust fan 352 in a state in which the spherical outer surfaces of the respective floating bodies 346 press the peripheries of the holes of the sealing packing 345, The outer surface of the spherical shape of the floating body 346 and the periphery of the hole of the sealing packing 345 are not opened.

The control unit 5 measures at least one of the position of each lifting body 336 inside each supply pore 337 and the position of each lifting body 346 inside each exhaust pore 347 And the result of the measurement indicates sealing of at least one of a connecting portion between each supply pore 337 and the air supply duct 331 and a connecting portion between each of the air discharge pores 347 and the exhaust duct 341, . That is, when two supply pores 337 and two exhaust pores 347 are installed on the horizontal plane, the two supply pores 337 and the two exhaust pores 347 are immersed in water of the same height As a result, the connection sites of the supply air pipes 337 and the air supply ducts 331 and the connection sites of the exhaust air pipes 347 and the exhaust ducts 341 are opened or sealed at the same time.

In this case, the control unit 5 controls the position of each lifting body 336 in each supply pore 337 and the position of each lifting body 346 in each of the exhaust pores 347 And depending on whether the measurement result indicates sealing of either the connecting portion between each supply pore 337 and the air supply duct 331 and the connection portion between the exhaust pores 347 and the exhaust duct 341 It is possible to control the driving of the fan 35 by determining that both the connecting portions of the supply air pipes 337 and the air supply ducts 331 and the connection portions of the exhaust air pipes 347 and the exhaust ducts 341 are sealed . Otherwise, the control unit 5 measures the position of each of the floating bodies 336 in the respective supply pores 337, and the measurement results are stored in the positions of the connection parts of the supply pores 337 and the supply air duct 331 The position of each of the floating bodies 346 in each of the exhaust pores 347 is measured and the results of the measurement are transmitted to the respective exhaust pores 347 It is possible to control the driving of the exhaust fan 352 depending on whether it indicates sealing of the connecting portion of the exhaust duct 341 or not.

The proximity sensors 338 and 348 are provided on at least one of the upper end of each supply pore 337 and the upper end of each pore 337 to move up and down in the inner space of each supply pore 337 Detects the proximity of the lifting body (336) and detects the proximity of each lifting body (346) moving up and down in the internal space of each exhaust pore (347). As shown in Figs. 1-3, the proximity sensors 338 and 348 include proximity sensors 338 installed at the upper end of each supply pore 337, and a proximity sensor 338 installed at the upper end of each pore 347 And a proximity sensor 348. That is, the proximity sensor 338 is inserted into the guide member 334 provided at the upper end of each supply pore 337 to detect the proximity distance between the proximity sensor 338 and each of the lifting members 336. Similarly, the proximity sensor 348 is inserted into a guide member 344 provided on the upper end side of each exhaust pore 347 to detect the proximity distance between the proximity sensor 348 and each of the floating bodies 346.

The controller 5 detects the proximity of each lifting body 336 moving up and down in the inner space of each supply pore 337, that is, from the proximity distance detected by the proximity sensor 338, The position of each of the floating bodies 336 in the inner space is measured and the proximity of each floating body 346 moving upward and downward in the internal space of each exhaust pore 347, that is, the proximity detected by the proximity sensor 348 The position of each of the lifting bodies 346 in the inner space of each exhaust perforated pipe 347 is measured from the distance. Whether or not the sealing of the connection portion between each supply pore 337 and the air supply duct 331 and the sealing of the connection portion between each of the air discharge pores 347 and the air discharge duct 341 depends on the amount of water introduced into the air conditioning portion 3 And a method of measuring the intensity of the light.

According to the present embodiment, the spherical outer surface of each of the levitation members 336 and 346 pushes the peripheries of the holes of the seal packing 335 and 345, thereby pressing the perforated pipes 337 and 347 and the ducts 331 and 341 The position of each of the levitated members 336 and 346 in the inner space of each of the porous pipes 337 and 347 is sealed by sealing the connection portions of the respective porous pipes 337 and 347 and the ducts 331 and 341 Can be expressed without error. In particular, the proximity sensors 338 and 348 can measure the proximity of each of the levitations 336 and 346 very accurately in a noncontact manner. The detection method described above can be applied to various types of detection methods such as the sealing of the connecting portion between each supply pore 337 and the air supply duct 331 and the sealing of the connection between each of the air discharge pores 347 and the exhaust duct 341 It is possible to detect very accurately whether or not the connection portion is sealed.

The control unit 5 determines whether the measurement result is the connection between the supply air duct 337 and the air supply duct 331 and the connection between the exhaust air duct 347 and the exhaust duct 341 When at least one seal is shown, the driving of the air supply fan 351 and the exhaust fan 352 is stopped. When any one of the connecting portion of the air supply duct 331 and the connecting portion of the exhaust pores 347 and the exhaust duct 341 is sealed, air circulation between the inner space and the outer space of the buried box 1 becomes impossible When it is determined that at least one of the connection portions between the supply air pores 337 and the air supply ducts 331 and the connection portions between the exhaust air pores 347 and the exhaust ducts 341 are sealed, The control unit 5 stops driving the air supply fan 351 and the exhaust fan 352 to prevent overheating of the air supply fan 351 and unnecessary power consumption.

The control unit 5 also indicates that the above measurement results indicate the opening of both the connecting portion between each supply pore 337 and the air supply duct 331 and the connection portion between each of the exhaust pores 347 and the exhaust duct 341 When the temperature of the internal space of the object is lower than the first threshold temperature, the driving of the air supply fan 351 and the exhaust fan 352 is stopped and the measurement result is transmitted to the air supply duct 331 And if the temperature of the internal space of the buried box 1 exceeds the first critical temperature and is equal to or lower than the second critical temperature, 351 and the exhaust fan 352 are driven. Here, the first critical temperature refers to the minimum temperature at which the built-in device 100 located in the inner space of the buried box 1 can be deteriorated when it is maintained for a long period of time (for example, 24 hours) The temperature refers to the minimum temperature at which the built-in instrument 100 can deteriorate in a short period of time (for example, one hour).

As described above, according to the present embodiment, in order to prevent deterioration or failure of equipment installed in the internal space of the buried box 1 due to overheating, and to minimize the power consumption due to the driving of the fans 51 and 52 The openings of both the connection portions of the supply air pipes 337 and the air supply ducts 331 and the connection portions of the exhaust air pipes 347 and the exhaust ducts 341 are shown, The supply fan 351 and the exhaust fan 352 are driven when the temperature exceeds the first threshold temperature and is equal to or lower than the second threshold temperature. That is, in the present embodiment, when the temperature of the internal space of the buried box 1 exceeds the first threshold temperature and is lower than the second threshold temperature, forced air circulation is performed between the internal space of the buried box 1 and the external space So that the equipment installed in the internal space of the buried box 1 can be rapidly cooled. When the temperature of the internal space of the buried box 1 is equal to or lower than the first threshold temperature, the opening of the connection portion between each supply pore 337 and the supply air duct 331 and the opening of each of the exhaust pores 347 and the exhaust duct 341, The device installed in the inner space of the buried box 1 can be cooled by the natural convection between the inner space of the buried box 1 and the outer space generated by the opening of the connecting portion of the buried box 1.

The control unit 5 controls the water cooler 42 of the cooling unit 4 when the temperature of the internal space of the buried box 1 exceeds the second threshold temperature irrespective of whether the internal space of the buried box 1 is sealed or not. . Even when the internal space of the buried box 1 is opened, the temperature of the built-in apparatus 100 located in the internal space of the buried box 1 can rise sharply for various reasons. The control unit 5 controls the water cooler 42 of the cooling unit 4 when the temperature of the internal space of the buried box 1 exceeds the second threshold temperature even when the internal space of the buried box 1 is opened, . Meanwhile, the control unit 5 indicates that the above-described measurement results indicate that both the connection sites of the supply air pores 337 and the air supply ducts 331 and the connection sites of the exhaust air pores 347 and the exhaust ducts 341 When the temperature of the internal space of the object exceeds the second threshold temperature, the water cooler 42 of the cooling unit 4 can be driven and the air supply fan 351 and the air discharge fan 352 can be driven. In this case, the inner space of the buried box 1 can be cooled most rapidly.

As described above, the control unit 5 indicates the opening of the connecting portion between the supply air duct 337 and the air supply duct 331 and the connecting portion between the exhaust air duct 347 and the exhaust duct 341, The air supply fan 351 and the exhaust fan 352 are driven when the temperature of the internal space of the internal combustion engine 1 exceeds the first threshold temperature and is equal to or lower than the second threshold temperature, When the critical temperature is exceeded, the water cooler 42 of the cooling section 4 is driven. The water cooler 42 of the cooling section 4 consumes a very large amount of electric power compared with the fan 35 of the air conditioning section 3 at the same time. As described above, according to the present embodiment, when the built-in device 100 in the internal space of the buried box 1 is overheated, the internal time of the cooling unit 4 is minimized according to the temperature of the internal space of the buried box 1, Cooling of the cooling unit 4 of the cooling unit 4 and the fans 351 and 352 of the air conditioning unit 3 by maximally utilizing the cooling by the natural convection, Consumption can be minimized.

According to the embodiments described above, the operation of the air conditioning part 3 for cooling the built-in appliance 100 by ventilating or sealing the internal space of the buried box 1 according to the inflow amount of the rainwater, 1, the driving of the cooling unit 4 for cooling the built-in appliance 100 is controlled by at least one of the enclosure of the internal space of the buried box 1 and the temperature, It is possible to provide an underground buried container system having a waterproof function for preventing flooding of the built-in apparatus 100 and a cooling function for cooling the built-in apparatus 100 located in a closed space under the ground only by consuming a very small amount of electric energy. As a result, electric facilities such as a high-voltage transformer and a high-voltage switch can be installed in the basement, so that the urban environment on the ground can be more pleasant. In addition, a fire caused by flooding or breakage of high- , Explosions, etc. will disappear and the safety of citizens in the city can be guaranteed.
