The base part 1 whose upper part is opened is formed of concrete or the like. The floor surface 2 of the base portion 1 is inclined from one end to the other end, and a water intake groove 3 is formed at the other end of the lowest floor surface 2, and the water intake groove 3 is provided with a water intake pipe 4. A connected cold water pit 5 is formed adjacent to the base portion 1. A pair of rails 6 parallel to each other are laid on both sides of the base portion 1, and a heat insulating structure 7 is installed on the rails 6. The rail 6 extends not only on the base portion 1 but also on the ground adjacent to the base portion 1 over almost the same length as the base portion 1, and the heat insulating structure 7 is shown in FIG. Between the closed position A which covers the upper part of the base part 1 and the open position B which is located on the ground adjacent to the base part 1 and opens the upper part of the base part 1 so as to be movable along the rail 6. ing.
[0009]
As shown in FIG. 2, the rail 6 is made of H-steel, and the pulley 8 attached to the lower part of the heat-insulating structure 7 rolls on the H-steel so that the heat-insulating structure 7 can move. ing.
The heat insulating structure 7 has a truss structure and a heat insulating structure in which a heat insulating material 11 having a thickness of 100 mm or more is inserted between the outer surface made of the reflective snow drift sheet 9 and the inner surface made of the moisture-proof sheet 10. ing. A plurality of fog spreaders 12 are attached to the ceiling portion of the heat insulating structure 7, and a plurality of sprinklers 13 are attached to the apex of the roof of the heat insulating structure 7.
[0010]
As shown in FIGS. 3 and 4, a trough 15 having a plurality of spouts 14 for flowing water on the floor surface 2 at one end of the floor surface 2 occupying the highest position among the floor surfaces 2 of the base portion 1. Is formed. The plurality of spouts 14 are formed at the same height. In addition, a strainer 16 for collecting dust mixed in the cold water is disposed on the intake groove 3 formed at the other end of the floor surface 2 and the intake connected to the intake groove 3 in the cold water pit 5 is also provided. A strainer 17 is disposed at the outlet end of the water pipe 4. Furthermore, in the cold water pit 5, a pump 18 serving as a cold water circulation device for sending cold water to a heat exchange unit described later, pumps 19 and 20 for sending cold water to the mist spreader 12 and the sprinkler 13, respectively, A drainage pump 21 is installed.
[0011]
As shown in FIG. 5, the pump 18 is connected to the inlet side of the heat exchange unit 23 in the building 22 constructed close to the base portion 1 via a pipe, and the outlet side of the heat exchange unit 23 is It is connected to the trough 15 of the base part 1 through piping.
[0012]
Next, the operation of this embodiment will be described. First, in the winter period, the heat insulating structure 7 is moved along the rail 6 to the open position B to open the upper part of the base part 1, and the snow removed or removed by heavy machinery is collected on the base part 1 Stack up. At this time, the snow block 24 having a specific gravity of 0.7 or more is formed by shaping the snow with a heavy machine. If the specific gravity does not increase to 0.7 or more just by leveling the snow due to the low moisture content of the snow, the specific gravity is reduced to 0. 7 or more dense snow masses 24 are formed. In this manner, when the snow block 24 having a predetermined size is formed, the heat insulating structure 7 is moved along the rail 6 to the closed position A, and the upper portion of the base portion 1 is covered with the heat insulating structure 7. Thereby, a snow ice warehouse is formed.
[0013]
Then, in the spring or summer, when the snow mass 24 in the snow ice warehouse starts to melt, the melted water of snow flows on the floor surface 2 of the inclined base portion 1 and is collected in the intake groove 3, and the intake pipe 4 Passed through and stored in the cold water pit 5. Therefore, the pump 18 is driven to send, for example, cold water having a temperature of 1 to 2 ° C. in the cold water pit 5 to the heat exchange unit 23 of the building 22 as shown by a one-dot chain line in FIG. Thereby, the cooling can be performed in the building 22. For example, water heated to a temperature of 5 to 6 ° C. by heat exchange in the heat exchange unit 23 is sent from the heat exchange unit 23 to the trough 15 of the base portion 1 through a pipe as shown by a broken line in FIG. And flows out from the plurality of spouts 14 to the floor surface 2 of the foundation 1. At this time, since the plurality of spouts 14 are formed at the same height, the water flows uniformly over the entire surface of the floor 2 without being biased toward a portion of the floor 2 of the base portion 1. This water is cooled by the snow mass 24 while flowing on the floor surface 2 of the foundation 1, returned to the cold water pit 5 together with new snow melt water, and sent again to the heat exchange unit 23 of the building 22 by the pump 18. The
[0014]
As described above, cooling of the building 22 is performed as necessary in spring, summer, and autumn.
When the temperature of the ceiling surface of the heat insulation structure 7 becomes high when the heat insulation structure 7 is located at the closed position A and the cooling system can be operated, the pump 19 is driven and the inside of the cold water pit 5 is driven. The cold water can be sent to the mist spreader 12, and the cold water can be sprayed in the form of a mist to lower the temperature. Similarly, when the temperature of the outer surface of the heat insulation structure 7 becomes high, the pump 20 is driven to send the cold water in the cold water pit 5 to the sprinkler 13, and the cold water is sprinkled on the roof of the heat insulation structure 7. Can be lowered.
[0015]
As shown in FIG. 6, when the temperature sensors 25 and 26 are attached to the ceiling portion and the roof of the heat insulating structure 7, respectively, and the temperature detected by the temperature sensor 25 exceeds a preset value. The water spray is automatically sprayed from the mist sprayer 12, and the water spray from the sprinkler 13 is automatically sprayed when the temperature detected by the temperature sensor 26 is equal to or higher than a preset value. It can also be configured.
[0016]
During the spring, summer or autumn period when the heat exchange unit 23 is used, the heat insulating structure 7 is positioned at the closed position A, and during the winter period when the heat exchange unit 23 is not used, the heat insulating structure 7 is positioned at the open position B. Therefore, for example, as shown in FIG. 7, if a sports facility such as a tennis court or a ground is created on the land corresponding to the open position B, the heat insulating structure 7 moves to the closed position A in the spring, summer or autumn. It is possible to use the sports facility as an indoor facility by using the sports facility as an outdoor facility and moving the heat insulation structure 7 to the open position B as shown in FIG. Become. Similarly, the heat insulating structure 7 can be moved to the open position B and used as a parking lot, a storeroom, or a warehouse in a severe cold season.
[0017]
It should be noted that since the snow removed or collected is collected to form the snow mass 24, there is a possibility that dust may be mixed in the melted water of the snow, but the dust is disposed on the strainer 16 and the cold water pit disposed on the intake groove 3. 5 is prevented from reaching the pumps 18 to 20 due to the collection by the strainer 17 disposed in the cylinder 5, so that it is possible to avoid the failure of the pumps 18 to 20 and the like.
[0018]
Since the heat insulating structure 7 is formed lightweight, it can easily move along the rail 6. Further, since the outer surface is made of the reflective drifting snow sheet 9, it reflects sunlight in the summer and slides down in winter without accumulating even if it snows. Furthermore, since the inner surface is formed from the moisture-proof sheet 10, moisture is blocked and the heat insulating effect by the heat insulating material 11 is promoted.
Further, as shown in FIG. 9, the sheet 27 is hung on the snow mass 24 having a specific gravity of 0.7 or more to form a space 28 between the heat insulating material 11 of the heat insulating structure 7, thereby The space 28 becomes a heat insulating space, and the heat insulating effect can be further improved. In addition, the sheet | seat 27 should just have moisture resistance, and can use various sheets, such as a vinyl sheet.
[0019]
Since the floor surface 2 of the foundation 1 is inclined, the trough 15 is formed at the highest position, and water is allowed to flow from the plurality of spouts 14 located at the same height, so that the melted snow is averaged, and the crepes are formed in the snow mass 24. Occurrence is prevented.
In addition, when the foundation part 1 becomes large-scale, the floor surface 2 is not inclined in one direction, but the center of the floor surface 2 can be made the lowest and the intake groove 3 can be formed there. For example, if the troughs 15 are installed in four directions and water is allowed to flow from a large number of spouts 14, the creeping of the snow mass 24 can be effectively prevented.
[0020]
In the above-described embodiment, the pulley 8 attached to the lower part of the heat insulating structure 7 is configured so that the heat insulating structure 7 can move by rolling on the rail 6 made of H steel. The rail 6 does not necessarily need to be formed from H steel, and a rail having another cross-sectional shape is used, or grooves such as a roll groove are formed on both sides of the base portion 1 instead of the rail, It can also be set as the structure where the wheel attached to the lower part of the heat insulation structure 7 rolls along this groove | channel.
[0021]
In the above embodiment, the heat insulating structure 7 has a truss structure with a pentagonal cross section. However, the structure is not limited to this. For example, the heat insulating structure 29 shown in FIGS. Various structures such as a truss structure having various cross-sectional shapes such as ˜31 and a dome structure such as the heat insulating structure 32 shown in FIG. 10D can be adopted.
[0022]
In the above description, the heat insulating structure 7 is movably installed. However, after the snow mass 24 is formed on the base portion 1, the heat insulating structure can be further assembled and fixed thereon. . In this case, a pillar can be set up in advance at a predetermined location of the foundation 1 and the roof portion of the heat insulation structure can be separately assembled on the ground and lifted with a crane to be finished on the pillar.
Furthermore, when the heat insulation structure becomes large and a pillar is necessary, a hole can be made in the snow mass 24 by slowly flowing a liquid from the top of the snow mass 24, and the necessary pillar portion It becomes possible to drill a hole only and attach a pillar there.
[0023]
Moreover, if a storage room is provided inside the heat insulating structure that forms the snow ice storage, it is possible to perform low-temperature storage of vegetables, grains, and the like.
[0024]
【The invention's effect】
As described above, according to the present invention, a snow mass having a specific gravity of 0.7 or more is arranged on the base portion by accumulating and shaping the snow that has been removed or removed in a predetermined place, and the base portion. Since the snow ice storage is formed by covering the top of the structure with a heat insulating structure, efficient cooling can be performed even if the volume of the snow ice storage is small.
In addition, the lining cost is remarkably reduced by using the snow removed or removed, and the initial cost can be reduced to 1/3 to 1/4 of the conventional by making the heat insulating structure movable. By moving the heat insulating structure, it can be used for sports facilities, events, parking lots, storerooms, warehouses, and other applications in the cold season, and an extremely useful cooling system is realized.
