Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary ice skating rink making apparatus, and more particularly to a temporary ice skating rink making apparatus temporarily used during a short-term ice skating rink show or a winter season.

[0002]

2. Description of the Related Art A conventional temporary ice skating rink manufacturing apparatus is laid mainly adjacent to a rectangular fence which is erected on the floor and serves as a peripheral wall of the ice skating, and on the floor in the fence. At the same time, a large number of U-shaped cooling tubes are provided outside the fence through openings formed by the brine supply port and the brine return port of the cooling tube below one side of the rectangular fence, and the cooling brine is flowed through the cooling tubes. It consisted of a cooling device. And
With cooling brine flowing through the cooling tube, water is sprayed inside the fence to freeze it. By repeating this watering and freezing, an ice surface having a predetermined thickness is formed to produce an ice skating rink. However, when water is sprayed, water easily leaks from the gap created in the opening, so moistened cloth or paper is packed in the gap as joint material, and the cloth or paper is frozen to block water leak in the gap. After preventing water leaks, water was sprinkled inside the fence to perform ice-making work.

By the way, this temporary ice rink is an ice rink that is used for a short period of time by using the floor surface of a gymnasium or the flat ground of a playground, unlike a dedicated ice rink used throughout the year. Therefore, it is required to shorten the production period as much as possible.

[0004]

However, in the case of the conventional temporary ice skating rink manufacturing apparatus, it takes time until the moistened cloth or paper packed in the gap freezes and water leakage from the gap is stopped. There is a drawback of this. For this reason, it is difficult to perform ice-making work in which water is sprayed inside the fence to thicken the ice surface, so it takes a long time to produce an ice skating rink, and it is required that the production period be short. There was a problem as a manufacturing device for the temporary ice rink to be used. In addition, since it takes time for the cloth or paper to freeze, water leakage may occur even while the cloth or paper is being frozen, and a newly moistened cloth or paper must be filled in the leaked area. It was complicated.

The present invention has been made in view of the above circumstances, and is a temporary ice skating rink capable of shortening an ice skating rink manufacturing time by stopping water leakage occurring during the ice skating rink manufacturing in a short time. An object is to provide a manufacturing apparatus.

[0006]

In order to achieve the above-mentioned object, the present invention is a fence which is erected on the floor and serves as a peripheral wall of an ice skating rink, and a fence which is adjacent to the floor in the fence. A large number of cooling tubes that are laid out, the brine supply port and the brine return port of which are exposed to the outside of the fence from an opening opening along the floor under the fence.
Brine supply means for supplying the cooled brine from the brine supply openings of the plurality of cooling tubes and cooling the warm brine returning from the brine return opening and supplying it again to the brine supply opening. In the temporary ice skating rink manufacturing apparatus for manufacturing an ice skating rink to form an ice surface with a predetermined thickness by gradually sprinkling water in the fence while freezing the cooling brine from the cooling tube to ice, At least one of a water leakage prevention cooling tube and a metal heat transfer member is provided along the opening.

[0007]

[Operation] Brine supply port and brine return port of many cooling tubes laid adjacent to each other on the floor in the fence,
It goes out of the fence through an opening that opens along the floor below the fence. Therefore, when water is gradually sprayed into the fence to freeze the fence, water is likely to leak from the gap formed in the opening.

Therefore, according to the present invention, at least one of the water leakage preventing cooling pipe and the metal heat transfer member is provided along the opening. Accordingly, when the cooling tube for water leakage prevention is provided in the opening, since cold heat from the cooling tube for water leakage prevention is supplied in addition to the cooling heat from the cooling tube, water is sprayed in the fence to cause icing. When this is done, the water in the opening can be quickly frozen. As a result, the water in the opening freezes and closes the gap generated in the opening, so that water leakage from the gap can be stopped in a short time. At this time, if a joint material such as a damp cloth or paper is filled in the gap in advance, water leakage can be stopped in a shorter time.

Further, when a metal heat transfer member is provided along the opening, the cold heat of the cooling tube is efficiently transferred to the entire opening via the heat transfer member, so that the inside of the fence is closed. When sprinkling water to freeze the water, the water in the opening can be quickly frozen. As a result, the water in the opening freezes and closes the gap generated in the opening, so that water leakage from the gap can be stopped in a short time. At this time, similar to the case where the cooling tube for water leakage prevention is provided, if a joint material such as moistened cloth or paper is packed in the water leakage portion of the gap in advance, the water leakage can be further shortened. Can be stopped.

When both the water leakage preventing cooling tube and the heat transfer member are provided in the opening, the water leakage can be stopped in a shorter time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a temporary ice skating rink manufacturing apparatus according to the present invention will be described in detail below with reference to the accompanying drawings. The temporary ice skating rink manufacturing apparatus of the present invention is an ice skating rink manufacturing apparatus that is temporarily used only in the winter season by utilizing a playground or a gymnasium, and it is required to shorten the manufacturing period and open it quickly.

FIG. 1 is an overall configuration diagram of a temporary ice skating rink manufacturing apparatus 10 of the present invention provided with a water leakage prevention cooling tube, FIG. 2 is a partially enlarged view of FIG. 1, and FIG. It is a principal part sectional view of FIG. Further, FIG. 4 is a schematic diagram (however, the cooling tube for water leakage prevention is omitted) showing the flow of the cooling brine (arrow in the figure) of the apparatus 10.

In the temporary ice skating rink manufacturing apparatus 10 of the present invention, a rectangular fence 12 serving as a peripheral wall of the ice skating rink is erected on a floor surface 11, and the fence 12 is provided.
A slender U with an outer diameter of about 8 mm is provided on almost the entire floor 11 inside.
A large number of V-shaped cooling tubes 14, 14, ...
They are laid in parallel with a pitch width of 0 mm. Incidentally, FIG.
2 and 4, the number of cooling tubes 14 is largely omitted.

The brine supply port 16 and the brine return port 18 of the large number of cooling tubes 14 are openings 2 formed between the lower end of one side of the rectangular fence 12 and the floor surface.
The brine supply port 16 is connected to the supply side sub-header 22 while the brine return port 18 is connected to the return side sub-header 24. Each supply side sub-header 22 is connected to the supply side main header 26, and each return side sub-header 24 is connected to the return side main header 2.
8 are connected to each. The supply side main header 26 is connected to the brine supply side of the cooling device 30, and the return side main header 28 is connected to the brine return side of the cooling device.

By the way, the reason why the brine supply port 16 and the brine return port 18 are passed through the lower side of the fence 12 is that when the upper side of the fence 12 is passed, the cooling tube 14 is exposed from the ice skating rink, which is dangerous to the skating competitor. Because. Further, a joint material 32 such as moistened cloth or paper is filled in the gap formed in the opening 20 (see FIG. 3). Further, in the temporary ice skating rink manufacturing apparatus 10 of the present invention, one U-shaped cooling tube 34 for preventing water leakage is arranged on the floor surface inside the fence 12 along the opening 20. . The cooling tube 34 for preventing water leakage is the cooling tubes 14, 14 ...
It is placed in a state where it intersects at a right angle. Further, the brine supply port 36 and the brine return port 38 of the water leakage prevention cooling tube 34 are provided on the fence 1 from the lower side of the fence 12.
2, the brine supply port 36 is connected to a water leakage preventing supply side sub-header 40, and the brine return port 38 is connected to a water leakage preventing return side sub-header 42. Further, the water leakage preventing supply side sub-header 40 is connected to the supply main header 26, and the water leakage preventing return side sub-header 42 is connected to the return side main header 28.

When the joint material 32 is sprinkled in the fence 12 and frozen by the cooling tube 14 and the water leakage prevention cooling tube 34, if there is almost no water leakage from the gap generated in the opening 20. , May not be used. Next, a method of manufacturing an ice skating rink by the temporary ice skating rink manufacturing apparatus 10 of the present invention configured as described above will be described.

The brine cooled to 0 ° C. or less by operating the cooling device 30 is supplied to the respective supply side sub-headers 22, 22 ... And the water leakage preventing supply side sub-header 40 via the supply side main header 26. . Each supply side sub-header 22
The brine supplied to each of the cooling tubes 14, 14 ... Reaches each of the return side sub-headers 18, 18 ... And returns to the return side of the cooling device 30 via the return side main header 28. On the other hand, the brine supplied to the water leakage prevention supply side sub-header 40 flows through the water leakage prevention cooling tube 34 to reach the water leakage prevention return side sub-header 42, and the cooling device 30 via the return side main header 28. Return to the return side of. In this way, with the cooling brine flowing through the cooling tube 14 and the water leakage prevention cooling tube 34, water is sprinkled into the fence 12 to freeze it. By repeating this watering and freezing, an ice surface having a predetermined thickness is formed to produce an ice skating rink. At this time, in order to shorten the production period of the temporary ice rink, the joint material 32 in which the water sprinkled in the fence 12 is filled in the gap of the opening 20 is used.
Immediately stop leaking outside the fence 12
It is necessary to carry out the ice making work by repeating watering and freezing in earnest.

Therefore, in the temporary ice skating rink manufacturing apparatus 10 of the present invention, the water leakage preventing cooling tube 34 is provided along the opening 20, and the cooling tube 14 and the water leakage preventing cooling tube 34 are both opened. It was made possible to supply cold heat to the part 20. Thereby, the opening 20
Since the cold heat supplied to the opening 20 becomes large and the water contained in the joint material 32 filled in the gap of the opening 20 and the water in the vicinity of the opening are quickly frozen, the gap formed in the opening 20 can be closed in a short time. . Therefore, since water can be sprinkled into the fence 12 in earnest to perform the ice making work, the ice skating rink making period is longer than that of the conventional temporary ice rink making device in which the water leakage prevention cooling tube 34 is not provided. Can be significantly shortened. As a result, the preparation period until the temporary ice rink is opened can be shortened, and the business period can be extended accordingly.

During the ice skating rink business, the ice near the opening 20 tends to melt and dull.
By arranging the water leakage preventing cooling tube 34 and increasing the supply of cold heat to the opening 20, it is possible to suppress the melting of ice, so that the management of the ice quality becomes easy. In FIG. 3, the water leakage prevention cooling tube 34 is arranged on the floor surface inside the fence 12 along the opening 20.
As shown in FIG. 5, the same effect can be obtained by disposing it in the opening 20.

Next, referring to FIGS. 6 to 10, a temporary ice skating rink manufacturing apparatus will be described in which the opening 20 is provided with a metal heat transfer member. The same members as those of the temporary ice skating rink manufacturing apparatus 10 provided with the water leakage prevention cooling tube 34 will be described with the same reference numerals. Although the overall configuration diagram of the temporary ice skating rink manufacturing apparatus of the present invention equipped with a metal heat transfer member is not shown, a water leakage preventing cooling tube 3 included in the above temporary ice skating rink manufacturing apparatus 10 is provided.
Instead of 4, the heat transfer member made of metal is provided along the opening 20. As the metal heat transfer member, a metal plate or a wire mesh is usually used. That is, as shown in FIGS. 6 and 7, a wire net 44 is provided inside the fence 12 so as to cover the opening 20, and the wire net 44 is brought into contact with the outer periphery of the large number of cooling tubes 14. As a result, the cold heat of the cooling tube 14 is efficiently transmitted to the entire opening 20 through the wire net 44, and the moisture contained in the joint material 32 filled in the gap of the opening 20 and the water near the opening are quickly frozen. Therefore, the gap generated in the opening 20 can be closed in a short time. Therefore, it is possible to stop the water sprinkled in the fence 12 from leaking from the gap in a short time.

Further, FIG. 8 shows a case where a wire net 44 is provided above the large number of cooling tubes 14 in the opening 20. Further, FIG. 9 shows a case where the wire nets 44 are provided above and below the large number of cooling tubes 14 in the opening 20. In the case of FIGS. 8 and 9, the wire netting 44 is the cooling tube 14.
Although not in contact with the cooling tube 14, it may be in contact with the cooling tube 14. Further, FIG. 10 shows a case where the wire net 44 is wound around the opening 20 of the cooling tube 14. Also in these cases, the cold heat of the cooling tube 14 is efficiently transmitted to the entire opening 20 via the wire net 44, and the water contained in the joint material 32 filled in the gap of the opening 20 or the water in the vicinity of the opening 20. Since the water freezes quickly, it is possible to stop the water sprinkled in the fence 12 from leaking from the gap in a short time.

In the above-mentioned embodiment, the cooling tube 34 for preventing water leakage or the heat transfer member made of metal is provided in the opening 20 so as to clarify each function and effect.
In addition, with the temporary ice skating rink manufacturing apparatus of the present invention that has both the water leakage prevention cooling tube 34 and the heat transfer member 44, water leakage can be stopped in a shorter time.

[0023]

According to the temporary ice skating rink manufacturing apparatus according to the present invention, the brine supply port and the brine return port of a large number of cooling tubes laid adjacent to each other on the floor surface inside the fence are provided on the lower side of the fence. At least one of the water-leakage-preventing cooling pipe and the metal heat transfer member is provided along the opening formed to extend from the fence to the outside of the fence. With this, when water is gradually sprayed into the fence to freeze the water, the water in the opening can be quickly frozen, so that water leakage that tends to occur in the opening can be stopped in a short time.

Therefore, it is possible to shorten the period until the ice skating rink is manufactured, as compared with the conventional temporary ice skating rink manufacturing apparatus which does not include the water leakage preventing cooling tube and the heat transfer member. Further, during the ice skating rink operation, the ice near the opening tends to melt and dull, but by providing at least one of a water leakage prevention cooling tube and a heat transfer member along the opening, This makes it easier to control the ice quality.
