［産業上の利用分野］
本発明は、スキー場に供給する人工雪を大量に造雪する
スノーガンに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a snow gun that makes a large amount of artificial snow to supply to ski resorts.
［従来の技術］
スキー場に供給する人工雪を造雪するスノーガンとして
、例えば、特公昭５９−１１８３５号公報に開示されて
いる構造のものが既に知られている。[Prior Art] As a snow gun for making artificial snow to be supplied to ski resorts, for example, one having a structure disclosed in Japanese Patent Publication No. 11835/1983 is already known.

に構成されている。As shown in Figure 4, this type of snow gun generates mist by colliding high-pressure water flowing in a thin spiral, indicated by the solid line arrow, with a compressed air stream flowing in a straight line, indicated by the dashed line. The fog is ejected from a fog nozzle outlet a opened at the front of the spray pipe A, and is configured to make snow by the cooling effect of low-temperature outside air.
［発明が解決しようとする課題］
ところで、造雪効率を向上させるためには、霧化効率を
向上させる必要があり、霧化効率の向上は空気と水の衝
突による霧の生成を良好にし、かつ霧径をできるだけ小
径にすることが要請される。そして、良好な霧の生成と
霧径の小径化は、空気と水が衝突する場合の接触面積の
増大および気水衝突時の相対速度の大きさに依存すると
されている。[Problems to be Solved by the Invention] By the way, in order to improve snow-making efficiency, it is necessary to improve atomization efficiency, and improving atomization efficiency improves the formation of fog by the collision of air and water. In addition, it is required to make the mist diameter as small as possible. It is said that good fog generation and reduction of the mist diameter depend on an increase in the contact area when air and water collide and on the magnitude of the relative velocity at the time of air-water collision.

ないため、大きい相対速度によって気水衝突を行なうこ
とが期待できない、したがって、良好な気水衝突状態お
よび霧径の小径化の点に関しては、いささか不十分であ
り、霧化効率と造雪効率に劣る問題点を有している。However, in the conventional snow gun, the compressed air injection pipe A
Since this method simply collides a thinly coiled high-pressure water stream with a compressed air stream injected in a straight line from the air, it is difficult to ensure a large contact area between water and air. In addition, since the compressed air is simply injected in a straight line from the compressed air injection pipe A without increasing its speed, it cannot be expected that air-water collision will occur due to a large relative velocity. It is somewhat insufficient in terms of collision conditions and reduction of the mist diameter, and has problems with poor atomization efficiency and snow-making efficiency.
本発明は、このような事情に鑑みなされたもので、良好
な気水衝突状態および霧径の小径化の達成により、霧化

目的としている。The present invention was made in view of the above circumstances, and aims to provide a snow gun that can improve atomization efficiency and snow-making efficiency by achieving good air-water collision conditions and reducing the diameter of the mist. .

いるものである。[Means for Solving the Problems] In order to achieve the above object, the snow gun according to the present invention is mounted at a position eccentric from the vertical axis of the snow gun main body so that high-pressure water is swirled within the main rest part of the snow gun. A high-pressure water introduction pipe to be introduced, a swirling chamber formed within the snow can main break section for swirling the high-pressure water flow flowing out from the introduction pipe, and a swirling chamber formed in communication with the front side of the swirling chamber to throttle the high-pressure water flow flowing out from the swirling chamber. A squeezing chamber concentric with the vertical axis of the snow gun body formed by a tapered truncated conical space that rotates while moving, and a water nozzle outlet that is formed concentrically at the front end of the squeezing chamber and opens to the air-water collision part. It has a high-pressure water moving system consisting of a compressor, which is installed at a position eccentric from the vertical axis of the snow gun main body and introduces compressed air into the main rest part of the snow gun so as to swirl it at high speed and in the opposite direction to the swirling direction of the high-pressure water flow. Compressed air consisting of an air introduction pipe and an annular constriction passage concentric with the vertical axis of the snow gun body, which rotates the compressed air flow flowing out from the compressed air introduction pipe toward the air-water collision part while gradually constricting it. The snow gun includes a moving system, and has a fog nozzle outlet formed on the longitudinal axis of the front end of the snow gun body for spouting the fog generated at the air/water collision part.
［作用］
本発明によれば、高圧水移動系の高圧水導入管からスノ

において、例えば右まわりに旋回する。[Operation] According to the present invention, the high-pressure water flow introduced into the snow gun main body from the high-pressure water introduction pipe of the high-pressure water transfer system swirls, for example, clockwise in the swirling chamber.
旋回室から絞り室に流下した高圧水流は、絞られること
によって流速を高められながら旋回し、水ノズル出口か
ら気水衝突部に噴射される。The high-pressure water flow that has flown down from the swirling chamber to the throttle chamber is throttled, swirls while increasing its flow velocity, and is injected from the water nozzle outlet to the air-water collision area.

回軌道に沿って、薄い水膜状になって旋回する。The high-pressure water stream injected from the water nozzle outlet to the air-water collision area is
Its turning radius is expanded by centrifugal force, and it turns along this expanded turning trajectory in the form of a thin film of water.

。On the other hand, the compressed air flow introduced into the snow gun body from the compressed air introduction pipe of the compressed air transfer system is throttled by flowing down the annular throttle passage while swirling in the opposite direction (counterclockwise) to the high-pressure water flow. flow rate is increased.

、霧径を小径化できる。The annular constriction passage is formed so that the compressed air flow can be rotated while being gradually constricted, so the compressed air flow is rectified into a laminar flow or a near-laminar flow and guided to the air-water collision area. In the air-water collision area, the compressed air flow that is rectified and swirls at high speed collides with the swirling high-pressure water flow in the form of a thin water film. In this case, the high-pressure water stream and the compressed air stream are swirling in opposite directions, so they collide with each other at high relative speeds. In other words, by colliding a rectified compressed air flow that is swirling at high speed with a high-pressure water flow that is swirling in the opposite direction in the form of a thin water film at a large relative speed, the air-water collision condition is improved. The mist diameter can be reduced.

突することになる。In the air/water collision section 8x, the rectified compressed air flow swirling at high speed collides with the swirling high-pressure water flow in the form of a thin water film. In this case, the high-pressure water stream and the compressed air stream are swirling in opposite directions, so they collide with each other at high relative speeds.

ることを特徴とするスノーガン。A high-pressure water introduction pipe is installed at a position eccentric from the vertical axis of the snow gun body and introduces high-pressure water so as to swirl it inside the snow gun body, and a high-pressure water introduction pipe is formed inside the snow gun body and swirls the high-pressure water flow flowing out from the introduction pipe. A squeezing chamber concentric with the vertical axis of the snow gun body, which is formed by a swirling chamber that communicates with the front side of the swirling chamber and that rotates while squeezing the high-pressure water flow flowing out from the swirling chamber. It has a high-pressure water transfer system consisting of a water nozzle outlet formed concentrically at the front end of this squeezing chamber and opening into the air-water collision area, and is installed at a position eccentric from the vertical axis of the snow gun body to supply compressed air. A compressed air introduction pipe is introduced into the snow gun main rest part so as to swirl at high speed in a direction opposite to the swirling direction of the high pressure water flow, and the compressed air flow flowing out from this compressed air introduction pipe is gradually directed toward the air water collision part. Equipped with a compressed air movement system consisting of an annular throttle passage concentric with the vertical axis of the snow gun body, which rotates while squeezing the snow gun.
A snow gun, characterized in that a fog nozzle outlet is formed on the longitudinal axis of the front end of the snow gun main body for spouting out the mist generated in the air/water collision part.
