Description

Technical Field

[0001] The present invention relates to the technical field of snowmaking machines, and in particular to an intelligent combined snowmaking machine and a control method thereof. Background Art

[0002] Currently, there are two types of artificial snowmaking technologies: cannonball-type snowmaking and crushed ice-type snowmaking. The cannonball-type snowmaking technology is temperature-sensitive and requires a certain amount of water to create snow when the ambient temperature drops below zero. This technology utilizes the low ambient temperature to condense water into ice, which is then instantly ejected to create snow. Crushed ice-type snowmaking involves crushing ice into flakes, allowing it to be created even at temperatures above zero. However, this technology consumes a significant amount of electricity. Achieving efficient snowmaking under varying conditions is a major challenge facing artificial snowmaking. Summary of the Invention

[0015] Furthermore, a control room is provided on one side of the snowmaking machine housing, and the electric control box is arranged inside the control room.

[0016] In order to achieve the above purpose 2, the present invention adopts the following technical solutions:

[0017] A control method for an intelligent combined snowmaking machine adopts the intelligent combined snowmaking machine as described above. When the second temperature sensing head detects that the ambient temperature is lower than 0 degrees, the electric control box controls the ends a and c of the first three-way solenoid valve to open, and end b to close, the water tank to supply water to the snowmaking cylinder, the motor and the fan to start, the snowmaking cylinder to start making snow, and snow is discharged from the first snow outlet; when the second temperature sensing head detects that the ambient temperature is greater than 0 degrees, the electric control box controls the ends a and c of the first three-way solenoid valve to open, and end b to close, the water tank to supply water to the ice-making device, the ends a and c of the second three-way solenoid valve to open, the ice-making device to start making ice, the centrifuge to crush the ice, and the snow is discharged from the second snow outlet.

[0019] The beneficial technical effects brought about by the present invention are:

Snowmaking can be achieved regardless of whether the temperature is below zero or above zero. The power consumption of the two snowmaking methods combined is much lower than that of the simple ice-crushing snowmaking method. BRIEF DESCRIPTION OF THE DRAWINGS
