Description

[Detailed description of the device] [Industrial applications]

TECHNICAL FIELD The present invention relates to an artificial snow manufacturing apparatus for snowfall at a ski resort or the like.

[Prior art]

In recent years, in order to prolong the skiing season, a ski resort is equipped with a water supply device and a snow making device including a snow making device. Although various types of snow making machines are commercially available in this case, it is general to use a method in which fine water particles are jetted from the nozzle into the atmosphere below freezing to cool and crystallize.

[Problems to be solved by the device]

However, when the atmospheric temperature is, for example, a warm winter of 1 ° C. or higher, snow cannot be produced, and when it is about 0 ° C. to −3 ° C., the snow making efficiency and the snow quality deteriorate. there were. In addition, since it is colder at night than during daytime and the ski area must be open during the daytime, snow can generally only be produced at night. Therefore, it was necessary to consider the pollution problem caused by noise. Moreover, when the wind was strong, it was necessary to take the wind direction into consideration when working. Further, in the case of this conventional method, there is a problem in that it is necessary to dispose a water supply pipe on the slope over a long length, resulting in enormous equipment cost. The present invention is intended to solve the above-mentioned drawbacks of the conventional artificial snow manufacturing apparatus and to provide an apparatus capable of efficiently manufacturing high-quality snow.

[Means for Solving the Problems]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention makes a front end opening of a tubular snow making chamber formed of a heat insulating material face a box-shaped snow accumulation chamber formed of a heat insulating material, and Is connected to the air conditioner, and the snow machine is installed near the rear of the snow making room.
It is characterized in that a snow outlet is formed on one side of the snow storage room, and the snow production room is classified into a fixed type and a mobile type.

[Action]

This device is installed in the proper place on the slope, and after cooling the tubular snow making room to about -5 ° C by the air conditioner, if the snow making machine is operated, the water droplets ejected from the nozzle of the snow making machine will be effective. It becomes snow and accumulates in the snow chamber. If this artificial snow is conveyed from the snow outlet to a desired place by using a belt conveyor or the like, a slope with a high quality artificial snow spread is formed.

【Example】

Next, an embodiment of the present invention will be described with reference to the drawings.
Is a shield formed by a heat-insulating plate material 1 to a length of about 30 meters. The plate material 1 is an outer wall 1a made of concrete, wood, etc. and an inner wall 1b made of cotton cloth, glass wool, etc. To do. The shield A includes a snow-making chamber A1 formed to have a thickness that does not hinder the injection of artificial snow, and a box-shaped snow-storing chamber A2 communicating with the tip opening of the snow-storing chamber A2. In some cases, it is formed into a state and installed directly on the ground. Next, reference numeral 2 is a cold air blowing port formed at one end of the snow making room A1, and a cooling device 3 is connected to the outer end thereof. Since this cooling device 3 is for keeping the inside of the snow making room A1 at a predetermined cooling temperature and humidity, it is provided with an automatic temperature controller and a wetting device. Reference numeral 4 denotes a hot air exhaust port provided at the upper end of the other end of the snow storage chamber A2.
Reference numeral 5 denotes a snow outlet provided on the other side of the snow compartment A2, and a door 6 is provided. The door 6 may be made of cloth, goodwill made of synthetic resin, or an air curtain. Further, when the outside air temperature is 0 ° C. to −3 ° C., snow is difficult to melt, so that there is no problem even if the outlet 5 is left open. Next, 7 is a snow making machine arranged near the rear side in the snow making room A1. In addition to the gun type that sprays water and compressed air from the nozzles in the snow making machine 7, a large number of gun type nozzles are provided in the wind tunnel to scatter the water and compressed air that are sprayed from the nozzles behind it. An air water type fan type with a fan, a number of nozzles that eject only water in the wind tunnel, a nozzle that ejects ice nuclei behind it, and a water droplet and ice nuclei behind it Air with a fan /
There is an airless fan type, but in this embodiment, the first gun type is used. Reference numeral 8 is a space for accumulating artificial snow formed on the other side of the snow storage room A2 so as to correspond to the snow outlet 5. Since one embodiment of the present invention has the above-mentioned structure, it is installed in a suitable place of a ski resort, and the cooling device 3 is used to make a snow-making room.
When the temperature in A1 is kept at, for example, −5 ° C. and the humidity is set to 80% and the snow making machine 7 is operated, the fine water droplets ejected from the nozzle 7 are immediately cooled and become snow, which accumulates in the snow chamber A2. Accumulate in space 8. In this case, 2,5m ³ about high-quality artificial snow is obtained in water of 1t. The artificial snow produced in this manner is carried out of the take-out port 5 to the outside by a belt conveyor having a tip inserted into the snow storage chamber A2, and transferred to the slope. Instead of the belt conveyor, an appropriate carrier such as a forklift may be used. Although the above embodiment is of a fixed type, the shield A may be provided with a traveling drive device so that it can be moved to various parts of the slope.

【effect】

According to the present invention, since the snow making room in which the snow making machine as described above is installed is formed into a cylindrical shape to reduce the wasted space, the temperature of the room is sufficiently cooled in a short time by the cooling device of low power. In addition to being able to do so, the temperature and humidity inside the snow making room can be easily adjusted, so that it is possible to produce a product with a desired snow quality. In addition, since the rate of water droplets sprayed from the snow making machine to be made into ultrafine particles (smoke) to the extent that it cannot turn into snow is small, it is possible to efficiently manufacture high-quality snow. As described above, the device of the present invention can efficiently produce high quality snow even if the atmospheric temperature is high, so that the ski season can be accelerated and the off season can be delayed. It is also possible to make snow regardless of the presence or absence of wind or day and night. Moreover, the manufacture of the artificial snow is
Since it is performed in the snow making room, noise is relatively low and it does not cause pollution. Furthermore, the artificial snow accumulated in the snow storage chamber can be easily carried out from the outlet to be laid on the slope, and unlike the conventional method, it is not necessary to bury the water supply pipe on the slope over a long length. There is an effect that the equipment cost can be significantly reduced.
