Abstract

PROBLEM TO BE SOLVED: To provide a method to generate an ice board on snow mechanically in a short time. SOLUTION: An elastic body which is being rotated at high speed is pressed to snow while moving. A surface layer of the snow is melted by friction heat between the snow and a rotating body, and heat generation by elastic deformation of the elastic body, thereby the ice board is generated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for generating an ice floe on snow in a short time, and facilitates manufacture of an ice-burn test road, a skating rink, etc. of a car or the like.

[0002]

2. Description of the Related Art In making snow ice such as a skating rink in a snowy area, it is necessary to wait for natural freezing after pressing snow and watering. However, in the initial stage of watering, water easily penetrates, so ice ice is generated. By then, large amounts of water and the natural conditions of sub-zero temperatures were required, and the formation of ice floes on snow required a lot of time and effort.

[0003]

The conventional method of producing ice floes by pressing snow and watering requires a large amount of water in the initial stage and the number of days required for finishing depends on natural conditions. The issue was how to create an ice floe at the beach.

[0004]

In order to solve the above-mentioned problems, an elastic body such as a tire is moved while rotating at a high speed, and the frictional heat generated by the elastic deformation of the rotating body causes the snow on the contact surface to be removed. Melt the surface to form an ice floe.

[0005]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 illustrates the principle of the formation of an ice floe. When the rotating body A is rotated at a high speed in the direction of R, the snow surface B increases the density of snow according to the weight W of the rotating body, Friction heat is generated on the contact surface of the rotating body A, and the snow on the contact surface D melts to form a film E of water.

F, in which the rotating body A is transverse to the rotation axis
In this direction, the water film E is instantaneously cooled by the compacted snow C to form an ice floe.

The rotating body preferably has a smooth surface and elasticity, and the surface layer can be efficiently melted by frictional heat with the snow surface and heat generated by elastic deformation.

Since the ice plate is instantaneously generated, FIG.
By changing the angle of the axis of the rotating body as shown in a and b, it is possible to generate an ice plate with a gradient.

[0009]

According to the present invention, an ice floe can be generated in a short time without using water on snow, so that the time required for generating an ice floe can be shortened and, at the same time, the generation of an ice floe having a gradient can be achieved. It is possible.
