本発明は人工降雪装置に係り、特にスキー場等に好適な
人工降雪装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an artificial snow-making device, and particularly to an artificial snow-making device suitable for ski resorts and the like.
雪は白という観念と、雪を着色してもすぐきたなくなる
という技術的先入観から、何か特別にマークする必要が
ある時のみ、雪の上に着色剤を散布して着色するほかは
、スキー場のゲレンデ等の雪を広範囲にわたって着色す
るという発想はなかった・
なお、この種のものとして関連するものには例えば特開
昭６１−３８３７４号が挙げられる。Due to the idea that snow is white and the technical preconception that even if you color the snow, it will quickly become messy, skiing is only done when there is a special need to mark it by spraying coloring agents on the snow. There was no idea of coloring a wide range of snow on ski slopes, etc. Related works of this type include, for example, JP-A-61-38374.
雪の上から着色剤または着色液を散布して雪を着色する
従来の方法は、下記の如き問題があった。The conventional method of coloring snow by spraying a coloring agent or a coloring liquid onto the snow has the following problems.
（１）着色剤は積雪の表層部のみを着色するのみであり
、また雪の結晶の表面または表面に近い層に浸透するの
みにて着色しているので、雪が融けるに従って着色剤が
流され、早期に色があぜでしまう。(1) The coloring agent only colors the surface layer of the snow, and it colors only by penetrating the surface of the snow crystal or the layer near the surface, so as the snow melts, the coloring agent is washed away. The color fades early.
（２）着色剤の多くが雪の結晶の表面に付着しているの
で１例えば、スキーヤ−が転倒したりすると、スキーウ
ェアに色が付いて汚してしまう。(2) Since most of the coloring agent adheres to the surface of snowflakes, for example, if a skier falls down, the ski wear will become colored and become dirty.
（３）異なる色に着色した雪が混じった時、雪がちょっ
と融けたりすると、表面の着色剤が混じるので、丁度絵
具を混ぜたのと同様に、暗い中間色になり、汚れた雪に
なってしまう。(3) When snow colored in different colors is mixed, if the snow melts a little, the coloring agent on the surface will mix, resulting in a dark neutral color and dirty snow, just like mixing paint.
上記の状況から、スキー場のゲレンデを大規模に、また
カラフルに着色することはできなかったし、そういう発
想もなかった。Due to the above situation, it was not possible to paint the slopes of the ski resort colorfully on a large scale, and there was no such idea.
本発明の目的は、大規模に、またカラフルに雪、 を
着色して、滑走コースを色で識別したり、ゲレンデに模
様や絵を描いたりすることによって、スキー場のイメー
ジを変え、はなやかな雰囲気を作って、安全で楽しいス
キー場を演出するのに好適な人工降雪装置を提供するこ
とにある。The purpose of the present invention is to change the image of ski resorts by coloring snow on a large scale and colorfully, identifying ski courses by color, and drawing patterns and pictures on ski slopes. To provide an artificial snow-making device suitable for creating an atmosphere and creating a safe and enjoyable ski resort.
上記目的を達成するため、着色した人を使って人工雪を
造ることにより、内部まで着色した氷粒からなる人工雪
が得られ、これをゲレンデに散布する様にしたものであ
る。In order to achieve the above purpose, by making artificial snow using colored people, artificial snow made of ice grains that are colored to the inside can be obtained, and this can be scattered on the slopes.
人工降雪装置において、高圧水または高圧水と圧縮空気
をノズルから低温空気中に噴霧し、これを氷結させて人
工雪を造る。できた人工雪は粒状を呈している。In an artificial snow-making device, high-pressure water or high-pressure water and compressed air are sprayed from a nozzle into low-temperature air, and the spray is frozen to create artificial snow. The artificial snow that is created has a granular appearance.
したがって着色した水を使って人工雪を造ることによっ
て着色した人工雪が得られる。Therefore, colored artificial snow can be obtained by making artificial snow using colored water.
以下、本発明の一実施例を第１．２．３図により説明す
る。An embodiment of the present invention will be described below with reference to FIGS. 1.2.3.
第１図は人工降雪装置の概略系整図を示す。スキー場の

移動させ、他のノズルに接続替えをして人工雪を散布す
ることにより、ゲレンデ１の全面に人工雪を散布するこ
とができる。An artificial snow machine 6 is connected to this branch pipe 4 using a flexible hose 5. The water in the water storage tank 8 is supplied to the water pipe 2 by the high-pressure pump 7, and the water is supplied to the water pipe 2 through the branch pipe 4. flexible hose 5
It is guided to the artificial snow machine 6 via. In the snowmaking machine 6, the supplied high-pressure water is sprayed into the low-temperature air from a nozzle together with high-pressure air as needed, and depending on the type of snowmaking machine 6, it is blown by a built-in blower to create a mist. The water will freeze and become artificial snow, which will be scattered on slope 1. Artificial snow can be spread over the entire surface of the slope 1 by moving the artificial snow machine 6 within the slope 1 using a self-propelled device or the like, changing the connection to another nozzle, and spreading the artificial snow.

When the coloring agent (coloring liquid) 13 in 3 is injected into the branch pipe 4 at a constant rate by the injection pump 11, the high pressure water in the branch pipe 4 is colored, and the colored high pressure water passes through the flexible hose 5 to the artificial pipe. The snow is sent to the snow machine 6 and sprayed from a nozzle to become colored artificial snow. A colored pattern can be drawn on the slope 1 by scattering this colored artificial snow on the slope 1 and by changing the color of the coloring agent depending on the spraying location. It is also possible to use a small-capacity artificial snow machine 6 to draw lines and letters with colored artificial snow.

である。The injection unit 10 is installed at the branch pipe 4 as shown in this figure.
However, the water pipe 2 or the water pipe inside the snowmaking machine 6 may be used. Of course, the same effect can be obtained by mixing a coloring agent into the water in the water tank 8. However, in this case, since the color cannot be easily changed, the entire slope 1 will be colored in one color, and it is also possible to change the color every -week.
