Abstract

PURPOSE:To make possible continuous operation of an ice-making apparatus and an apparatus for forced feeding of snow by supplying a plurality of snow- storing spaces with snow by the use of a snow-guiding means provided between the ice-making apparatus and a snow-storing means. CONSTITUTION:Snow 60 produced by an ice-making apparatus 10 is guided, by the use of a shoot 13, to either of storage tanks 12A, 12B and heaped up therein until the tank becomes full. When one of these storage tanks becomes full, the shoot 13 is turned so that the other storage tank is filled. The snow 60 thus stored in the storage tank is taken out through an ice outlet 12a, put into a feeder 5, and from thence sent under pressure of air by a blower 6 to a skiing slope to be spread there. The inside 12p, 12s of each of the storage tanks 12A, 12B is so designed as to allow the snow 60 therein to be freely taken out so that in case of trouble with the ice outlet of one storage tank snow 60 can be taken out of the other storage tank and fed by the use of a means for feeding snow under pressure to the slope and spread thereon. The shoot 13 can be freely removed from above the inside 12s, 12p.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow and ice storage facility suitable for application to a ski slope on an artificial ski resort.

[0002]

2. Description of the Related Art FIG. 3 is a schematic view showing an example of an artificial snowfall system used in a conventional artificial ski resort. Conventionally, an artificial snowfall system 21 used in an artificial ski resort, for example, as shown in FIG. 3, is composed of an ice making device 22, an ice storage 29, and an ice and snow pressure feeding device 23, and the ice and snow pressure feeding device 23 includes an ice and snow feeder 25. Ice and snow 6 supplied to
It has a conduit 28 for pumping 0. That is, water 61 is supplied to the ice making device 22 by a pump or the like (not shown), and the ice making device 22 is made to produce ice and snow 60 from the water 61 supplied thereto. In this way, the ice and snow 60 produced by the ice making device 22 is stored in the ice storage 29. Then, when it is necessary to spray ice and snow on the slope 40, the ice and snow 60 is taken out from the ice storage 29, and the ice and snow 60 is supplied to the ice and snow feeder 25 of the ice and snow pumping device 23. Further, in the ice and snow pumping device 23, the blower 26 is driven to suck the outside air into the pipe 28 through the air filter 26a and compresses the compressed air 51, and the compressed air 51 heated by the adiabatic compression of the blower 26, The heat exchanger 27 such as an intercooler returns the temperature to the temperature before intake and generates air 50.
Supply to. And ice and snow 6 supplied from the ice storage 29
0 and the air 50 cooled by the heat exchanger 27 are mixed in the ice and snow feeder 25. Then, the ice and snow 60 supplied from the ice and snow feeder 25 into the pipe line 28 is crushed by the collision with the inner wall of the pipe line 28 and the like into small pieces while being compressed by air, and passes through the ice and snow pressure feed pipe 30 to the slope 40.
Is supplied to. Therefore, the small pieces of ice and snow 60 are used to form the first and second to n-th spraying areas 41 and 42 that form the slope 40.
4n, the openable and closable first and second to nth outlets 31, 32 to 3n were taken out via the spray hose 35, and the ice and snow 60 was sprayed in each spray area 4n. .

[0003]

However, in the artificial snowfall system 21 as described above, when the ice storage box 29 is filled with the ice-snow 60 produced by the ice-making device 22, the ice-snow 60 is fed through the ice-snow pressure feed pipe 30. If you do not spray it on the slope 40,
No more ice 60 can be stored in the ice storage 29. Therefore, from the time when the ice storage 29 is full until the ice and snow spraying work proceeds to some extent, the ice making device 22
It is necessary to stop the production and supply of the ice and snow 60 due to the above, and there is a disadvantage that the operating rate of the ice making device 22 is reduced accordingly. In addition, if the ice outlet 29a of the ice storage 29 should fail while the ice storage 60 supplies ice and snow 60 to the ice and snow feeder 25 for the ice and snow spraying work, during this time, the ice and snow 60 to the ice and snow supply pipe 30 Supply stops. Then, until the ice outlet 29a is repaired, there is no choice but to stop the ice and snow pumping device 23, and during this period, the slope 4
The supply and distribution of the ice and snow 60 to 0 is interrupted. Furthermore, while the ice and snow pumping device 23 is stopped, the ice and snow 6 in the ice storage 29 is
Since 0 does not decrease at all, the ice making device 22 must be stopped. Therefore, the ice storage 29 becomes full,
Alternatively, even if the ice outlet 29a fails, the ice making device 22
If there is no need to stop the ice and snow pumping device 23, it is possible to increase the operation rate of the ice making device 22 and the ice and snow pumping device 23 to increase the amount of ice and snow supply to the slope 40.
It is very convenient. Therefore, in view of the above circumstances, the present invention enables continuous operation of the ice making device and the ice and snow pumping device,
The purpose is to provide a snow and snow storage facility.

On the right side of the feeder 5 in FIG. 1, a blower 6 for pumping the ice and snow 60 in the feeder 5 is installed in the ice and snow transport space 3
The heat exchanger 7 is connected to the blower 6 in such a manner that the compressed air 51 generated and discharged by the blower 6 is cooled and adjusted to a predetermined temperature. The air 50 is provided in the feeder 5 at a predetermined pressure. Therefore, snowmaking plant 2

The inside 12 of either of the two storage tanks 12A and 12B
The ice and snow 60 stored in p, 12s is connected to the ice and snow supply pipe 30 so as to form ice and snow supply pressure supply means for supplying and supplying ice and snow 60 through the pressure of the air 50.

On the left side of FIG. 1 which is the discharge side of the feeder 5, the ice and snow pressure feed pipe 30 is connected so as to connect the snowmaking plant 2 and the slope 40, as shown in FIG. In the inside of the ice / snow transport space 30s, the ice / snow 60 discharged and supplied from the feeder 5 to the feeder / snow transport space 30s can be transported through the ice / snow transport space 30s in the direction of the arrow E in FIG. , Is formed to have a circular cross-sectional shape over its entire length. Ice and snow pressure pipe 30
Are installed here in a form corresponding to the ups and downs of the slope 40, and the ice-and-snow pressure-feeding pipe 30 is provided with first and second to n-th outlets 31, 32 to 3n that can be selectively opened and closed. , The first and second spray areas to the n-th spray area 41 of the slope 40,

At each outlet 3n, a spray hose 35 is connected to each spray area 4n of the slope 40 in such a manner that the inside of each spray hose 35 and the ice-snow transport space 30s are in communication with each other. The ice / snow 60 fed under pressure into the ice / snow transport space 30s of the ice / snow pressurizing pipe 30 can be discharged from the discharge port 35a, which is the tip of the opening, toward each spraying area 4n of the slope 40.

Artificial ski resort 39 and artificial snowfall system 1
Has a configuration as described above, in order to spray the snow 60 on the slope 40, the ice making device 10 of the snow making plant 2 makes the snow 60 having a substantially predetermined particle diameter, and The inside 12 of one of the storage tanks 12A12B of the ice storage 11
Store ice in p, 12s. When the ice and snow 60 is sprayed, the ice and snow 60 is taken out from the ice and snow outlets 12a and 12b of either of the storage tanks 12A and 12B, and the ice and snow 6 is discharged.
0 using the ice-and-snow pressure-feeding device 3 through the ice-and-snow pressure-feeding pipe 30 in the direction of arrow E, which is the ice-and-snow transport direction, on the slope 4
0, and the ice / snow 60 that has been transported is discharged from the discharge port 35a of any spray hose 35 so that each spray area 4
Spray every n.

Therefore, first, the ice making device 10 is operated to make ice and snow 60, and the ice and snow 60 is stored in the inside 12p, 12s of one of the two storage tanks 12A, 12B of the ice storage 11. . At this time, the chute 13 is positioned here so as to extend over the insides 12p and 12s of the storage tanks 12A and 12B, as shown by the solid line in FIG. 2, and the ice making device 10 is manufactured using the chute 13 and The ice / snow 60 dropped from the outlet 10a is guided by sliding along the slide surface 13a, and the ice / snow 60 is guided to the inside 12p12s.
To either of them. Therefore, for example, in FIG.
1, the slide surface 13a of the chute 13 is moved through the drive mechanism 15 to the inside 12 of the storage tank 12B shown on the right side in FIG.
The ice-snow 60 is turned down to s, and either or both of the two ice-making devices 10 and 10 are operated in this state, so that the ice / snow 60 is passed through the outlet 10a.
Drop to 3a. Then, the ice and snow 60 moves on the slide surface 13.
In the form in which it slides on a and falls into the inside 12s of the storage tank 12B shown on the right side of FIG.
Ice is stored here. At this time, the two ice making devices 10,
Even if any one of them breaks down, the ice-and-snow 60 is continuously manufactured in such a manner that the other ice-making device 10 continues to operate during the repair of one of the broken ones.

Thus, the inside 12 of the storage tank 12B on the right side of FIG.
When s becomes full, the chute 13 is swung about the swing shaft 151 in the direction of arrow B in FIG.
Is turned to the inside 12p of the storage tank 12A on the left side of FIG. (That is, the state shown by the solid line in FIG. 2 is obtained.)
Then, in this state, the ice and snow 60 produced by the ice making device 10
Is dropped from the outlet 10a onto the slide surface 13a, slidably moves on the slide surface 13a and falls to the low inclination side, and is supplied and stored in the inside 12p of the storage tank 12A on the left side of FIG. Go. That is, even if the inside 12s of the storage tank 12B on the right side of FIG. 1 is full, it is not necessary to stop the operation of the ice making device 10, and the ice making device 10 is continuously operated,
Ice and snow 60 can be stored in the interior 12p of the storage tank 12A on the left side of FIG. Therefore, since the ice making device 10 is continuously operated, its operating rate is good. Further, the storage tank 12 for storing the ice and snow 60 produced by the ice making device 10 in this way
In order to switch between A and 12B, by simply swinging the chute 13 in the directions of arrows A and B through the drive mechanism 15 to change the ice and snow guide movement direction, the interiors 12p and 12s to be stored ice can be easily stored. You can choose.

Thus, the inside 12 of the storage tank 12A on the left side of FIG.
While storing ice in p, as described above, in the filled storage tank 12B on the right side of FIG. 1, the ice outlet 12b is opened, and the ice and snow 60 stored in the inside 12s is fed to the feeder 5. Input and supply a specified amount per unit time. At the same time, the blower 6 is driven to generate the compressed air 51 by sucking the outside air from the air filter 6a and compressing the outside air, and the compressed air 51 is heat-exchanged through the heat exchanger 7 to lower the temperature. The air 50 is supplied to the feeder 5 at a predetermined pressure. Then, the feeder 5 mixes a predetermined amount of ice and snow 60 with the air 50, and supplies this by pressure to the ice and snow transfer space 30 s of the ice and snow feed pipe 30. Thus, the feeder 5 and the blower 11 are used for the ice and snow transport space 30s.
The ice and snow 60 that has been pressure-fed and supplied to the slope 40 is transported from the snowmaking plant 2 to the slope 40 by the pressure of the air 50 that has dropped to a predetermined temperature. Therefore, when the arbitrary outlet 3n is opened, the ice / snow 60 transported in the ice / snow transport space 30s is
Spray hose 3 attached to the opened outlet 3n
5 is discharged from the discharge ports 35a toward the corresponding spraying areas 4n. The ice and snow 60 thus produced by the ice making device 10 is dispersed and scattered over the entire surface of the slope 40.

In this way, while the ice and snow 60 in the storage tank 12A on the right side of FIG. 1 is being transferred and sprayed to the slope 40, the ice making device 10 produces the ice and snow 60 without rest, and this is stored in the storage tank 12B on the left side of FIG. It continues to be supplied, but during this work,
When the ice outlet 12a of the right storage tank 12A fails, the ice outlet 12a of the left storage tank 12A in FIG. Then, the ice outlet 1 of the storage tank 12A
Even when 2a is out of order and is being repaired, it is not necessary to stop the operation of the blower 6 or the like that constitutes the ice and snow pumping device 3, and the ice and snow 60 is continuously supplied and pumped to the ice and snow pumping pipe 12. The ice and snow spraying work can be continued in each spraying area 4n of the slope 40. In this way, while continuously operating the ice making device 10, the slide surface 13a of the chute 13 is changed in direction through the drive mechanism 15 to change the moving direction of the ice and snow 60 on the slide surface 13a. Ice and snow 60 is stored in the interiors 12p and 12s of the two storage tanks 12A and 12B, respectively, and the feeder 5 is supplied from the respective ice outlets 12a and 12b.
The ice and snow 60 are alternately supplied to. Then, since there is no need to rest the ice-snow pumping device 3 during the ice-snow spraying work, the operation rate of the ice-snow pumping device 3 is high, which results in
Ice and snow 60 are continuously supplied and scattered on the slope 40, and the total amount of ice and snow 60 supplied and scattered on the slope 40 increases. Therefore, regardless of the weather of the artificial ski resort 39 and the service conditions thereof, a sufficient amount of snow required for the slope 40 can always be stably secured.

Further, in the snow making plant 2, by driving the two ice making devices 10 and 10 at the same time, the inside 12 of the two storage tanks 12A and 12B of the ice storage tank 11 is driven.
It is also possible to store ice and snow 60 on p and 12s at the same time in a short time. To this end, by rotating the chute 13 through the drive mechanism 15 in the direction of arrow C or D in FIG. 2 which is a direction intersecting with the plane of FIG. Two storage tanks 12A,
The chute 13 is arranged between 12B so as to extend in a direction intersecting the plane of FIG. Then shoot 13
Has a shape retracted from above the insides 12p and 12s of the two storage tanks 12A and 12B. In this state, when the two ice making devices 10 and 10 are made to produce ice and snow 60 respectively, and the ice and snow 60 is dropped from the outlets 10a and 10a toward the ice storage 11, the ice and snow 60 comes into contact with the chute 13. Without internal 12p, 12s directly from each ice making device 10
Ice is stored here in the form of falling and moving to. Thus
Ice and snow 60 is fully stored in the interior 12p, 12s of both the storage tanks 12A, 12B in a short time. Therefore, even while the ice-snow pumping device 3 is stopped and the ice-snow 40 is not sprayed to the slope 40, a large amount of ice-snow 60 is prepared in the ice storage 11 in this way to store the ice-snow 60.
When a large amount of spray supply is required, the required amount of ice and snow 60 can be immediately supplied from the inside 12p, 12s of the storage tanks 12A, 12B to the ice and snow pressure-feeding pipe 12.

Further, in the snowmaking plant 2, as described above, the chute 13 is retracted from above the insides 12p and 12s of the two storage tanks 12A and 12B via the drive mechanism 15. Two ice making devices 10, 10
It is also possible to operate only one of the ice making devices 10 and store the ice and snow 60 in only one inside 12p or 12s of the two storage tanks 12A and 12B via the outlet 10a. Therefore, when the amount of ice and snow 60 required for the slope 40 is small, by resting one ice making device 10 and one storage tank 12A or 12B in this way, the driving energy required for driving the ice making device is approximately halved. You can save just that.

Therefore, if the artificial snowfall system 1 is used,
In the snowmaking plant 2, the two storage tanks 12A and 12B of the ice storage 11 are connected via the chute 13 as described above.
The ice and snow 60 are guided so as to be distributed to the insides 12p and 12s of the ice, and the ice and snow 60 is stored in the ice and ice 60 respectively, thereby enabling continuous operation of the ice making device 10 and the ice and snow pumping device 3, and the ice making device 10 and the ice and snow While it is possible to increase the operation rate of the pumping device 3 and increase the amount of ice and snow 60 supplied to the slope 40, it is necessary to store ice by using only one of the two storage tanks 12A and 12B. It is also possible to save energy. Therefore, ice and snow 60
It is always possible to manufacture and disperse this to the slope 40 in a form corresponding to the operation and failure conditions of the devices constituting the artificial snowfall system 1 and the slope conditions.

The ice and snow guiding means such as the chute 13 is
At least the ice and snow 60 produced by the ice making device 10 can be received, and the ice and snow moving surface such as the slide surface 13a can be turned in such a manner that the ice and snow 60 can be selectively supplied to any of the plurality of ice and snow storage spaces. If so, the configuration may be other than that described in the embodiment. Therefore, the chute 13 in the embodiment is configured so that the arrows A and B are passed through the drive mechanism 15.
By swinging in the direction, the ice-snow moving surface such as the slide surface 13a can be turned, and at the same time, the arrow C,
By rotating in the D direction, the chute 13 can be positioned above the insides 12p and 12s of the two storage tanks 12A and 12B and can be retracted from above the insides 12p and 12s. Although an example has been described, the ice and snow guide means may be provided so as to be positioned and fixed on the two storage tanks 12A and 12B in such a manner that the ice and snow movement surface such as the slide surface 13a thereof can be simply turned. . The structure of the drive mechanism 15 provided in the chute 13, that is, the method of changing the direction of the ice and snow moving surface such as the slide surface 13a and the method of positioning and retracting the chute 13 are arbitrary. In addition, the snow and snow moving surface such as the slide surface 13a formed on the chute 13 is not necessarily formed so that the ice and snow 60 can be slid and moved. It may be transported or moved, or the ice and snow 60 may move while rotating.

Further, in the above-described embodiment, two storage tanks 12A and 12B are installed in the ice storage 11 as storage means for storing the ice and snow 60 produced by the ice making device 10. The inside 12p of the storage tanks 12A, 12B, 1
Although the example in which 2s is used as the ice and snow storage space is described, the ice and snow storage space is provided in a plurality of storage means such as the storage tanks 12A and 12B so that the ice and snow 60 stored in the ice and snow storage space can be respectively taken out. If so, it may be present in other forms. Therefore, a plurality of ice and snow storage spaces may be formed in the storage means for storing the ice and snow 60 by dividing the storage means through a partition plate or the like. The storage means and the number of ice and snow storage spaces formed therein are arbitrary. In addition, the method for taking out the ice and snow 60 from the ice and snow storage space such as the interiors 12p and 12s is as long as the ice and snow 60 can be smoothly supplied to the ice and snow pumping device such as the feeder 5.
The extraction method is arbitrary. In the examples,
An example in which two ice making devices 10 and 10 are installed in the snowmaking plant 2 has been described, but the number of the ice making device 10 may be one. Further, in the embodiment, in the snow making plant 2 which is the snow and snow storage equipment, the ice and snow 60 produced by the ice making device 10 is stored inside the storage tanks 12A and 12B of the ice storage 11 in the inside 12p,
The example in which the ice and snow spraying work is carried out by the artificial snowfall system 1 by storing ice in 12s and sending the ice and snow by the ice-and-snow pumping device 3 to the ice-and-snow pumping pipe 30 through the air 50 has been described.

As described above, according to the present invention,
Storage means such as storage tanks 12A, 12B having the ice making device 10 for storing the ice and snow 60 produced by the ice making device 10 is provided, and a plurality of ice and snow storage spaces such as the interiors 12p, 12s are provided in the storage means. Ice and snow stored in each ice and snow storage space 6
0 is formed in a freely removable form, and the ice making device 10
An ice / snow guide means such as a chute 13 is provided between the ice storage means and the storage means in a form in which the ice / snow 60 manufactured by the ice making device 10 can be received, and the ice / snow guide means is provided with an ice / snow movement surface such as a slide surface 13a. Since the ice-and-snow 60 received by the guide means from the ice-making device 10 is provided so as to be capable of being turned to be able to be supplied to any of the plurality of ice-snow storage spaces, the ice-snow guide means changes the direction of the ice-snow moving surface. As a result, the ice / snow 60 can be guided to one of the plurality of ice / snow storage spaces by changing the moving direction of the ice / snow 60 manufactured by the ice making device 10 and received by the ice / snow guiding means. Therefore, the ice and snow 60 produced by the ice making device 10 is guided to one of the plurality of ice and snow storage spaces via the ice and snow guide means and is stored here until one ice and snow storage space is full. It When the ice-snow storage space is full, the ice-snow 60 manufactured by the ice-making device 10 is changed in such a manner that the direction of movement of the ice-snow 60 is changed by changing the direction of the ice-snow moving surface. Then, the ice and snow storage space will be supplied and stored in a separate ice and snow storage space. Therefore, even if one ice and snow storage space is full, it is possible to continuously operate the ice making device 10 without waiting for the ice and snow 60 to be taken out of the ice and snow storage space to create an empty space. Therefore, even if one ice and snow storage space is full, the ice making device 10 is continuously operated without stopping and the ice and snow 60 is continuously supplied to another ice and snow storage space space. Therefore, the operation rate of the ice making device 10 is high. Therefore, it is possible to manufacture a large amount of ice and snow 60 and store it. Further, in such an ice and snow storage facility, the ice and snow 60 stored in the ice and snow storage space is taken out in a form of being put into the feeder 5 or the like from the ice take-out port 12a or the like, and the ice or snow is sent by an ice-and-snow pumping device constituted by a blower 6 or the like. Supply and spray on the slopes by pressure. At this time, in the present invention, as described above, the plurality of ice and snow storage spaces are formed so that the ice and snow 60 stored in each of the ice and snow storage spaces can be respectively taken out from the ice and snow storage spaces. If the ice outlet of one ice and snow storage space fails during the supply and spraying work, the ice and snow 60 stored here is taken out from another ice and snow storage space different from the one where the ice and snow storage outlet has failed, and this is transferred to the ice and snow pumping device. It can then be continuously sprayed on to the slopes. Therefore, even if the ice outlet of one ice and snow storage space fails, it is not necessary to stop the ice and snow pumping device, and the ice and snow pumping device can be continuously operated. In this way, by continuously operating the ice and snow pumping device, it is possible to increase the amount of spraying supplied to the slope. Therefore, by using the ice and snow storage facility according to the present invention, a sufficient amount of snow can be always secured on the slope of the artificial ski resort.

Further, the ice making device 10 includes the storage tanks 12A and 1A.
The chute 13 is arranged above the storage means such as 2B.
When the ice and snow storage equipment is configured such that the ice and snow guide means such as the above can be positioned above the plurality of ice and snow storage spaces such as the interiors 12s and 12p and retractable from above the ice and snow storage space. When the guide means is retracted from above the plurality of ice and snow storage spaces, the ice and snow 60 produced by the ice making device 10 can directly move from the ice making device 10 to the plurality of ice and snow storage spaces. Therefore, when the ice and snow 60 produced by the ice making device using the ice and snow guide means is selectively supplied to any of the plurality of ice and snow storage spaces, the ice and snow guide means of the plurality of ice and snow storage spaces is used. Position it above. As a result, as described above, a large amount of ice and snow can be supplied to the slope 40 by continuously operating the ice making device and the ice and snow pumping device and increasing the operating rate thereof. If the ice and snow guide means is unnecessary, the ice and snow guide means is retracted from above the ice and snow storage space.
The ice and snow 60 produced by the ice making device 10 can be moved directly to the ice and snow storage space and stored there. As a result, it is possible to arbitrarily select the method of manufacturing, storing and supplying ice and snow.
