CN115218573B - A snowmaking machine that automatically adjusts the collision position - Google Patents

Abstract

The invention discloses a snowmaking machine which can automatically adjust the collision position. The snowmaking machine comprises a nozzle, a nucleator, an air cylinder, a water pump, an air compressor and a fan. The snow gun can sense different ambient temperatures and automatically adjust the jet angle of the nucleator to change the collision position of the ice crystal nuclei and water droplets. When the ambient temperature is high, the heat transfer rate of water droplets is slow, and it takes a long time for ice crystal nuclei to freeze. Therefore, it is necessary to increase the flight distance before collision to ensure the formation of ice crystal nuclei. When the ambient temperature is low, the freezing time of ice crystal nuclei is shorter, so the flight distance before the collision can be reduced, and the water droplets after the collision can be frozen for a longer time to improve the quality of snow. The invention can adapt to snowmaking under different temperature conditions, automatically adjusts the collision position, improves the quality of snow, and is automatic and efficient, saving manpower and material resources.

Description

A snowmaking machine that automatically adjusts the collision position

technical field

The invention belongs to the technical field of snowmaking machines, and in particular relates to a snowmaking machine for automatically adjusting the collision position.

technical background

As an artificial snowmaking equipment that provides stable snow resources, snowmaking machines are already one of the essential equipment for winter ski resorts to ensure their operation. At present, the most widely used internal hybrid snowmaking machine uses the nuclear device and the swirl nozzle as the core atomization components. The high-pressure water is sprayed and atomized through the nozzle to form fine water droplets, and the high-pressure water and compressed air are atomized into smaller water droplets through the nuclear device. The atomized water droplets of the nuclear device have smaller particle size, larger heat transfer specific surface area, faster heat transfer, and less cooling required, so they will freeze quickly at the outlet to form ice crystal nuclei, and the ice crystal nuclei will catalyze after colliding with small water droplets. The water droplets freeze, causing the water droplets to freeze to form snowflakes before hitting the ground. As the key to snow formation, ice crystal nuclei should not only ensure that the ice crystal nuclei freeze before they collide with water droplets, which can catalyze the freezing of water droplets; but also ensure that the collided water droplets can freeze into snow before they fall to the ground, preventing liquid water from falling to the ground and seriously affecting snow quality. Therefore, it is necessary to adjust the collision position between ice crystal nuclei and water droplets according to the actual ambient temperature, and to gain more time for water droplets to freeze under the premise of ensuring the formation of ice crystal nuclei, so as to control the quality of snow.

Every n nozzles and 1 nucleator form a group. It is recommended The value of n is 3.

As shown in FIG. 1 , the tail of the nuclear device 2 can rotate around the rotating shaft 7 , and the middle part is supported by a fixed fulcrum 8 . The pillar below the rotating shaft 7 is a thermal expansion material 9, which can expand and contract according to the ambient temperature to change the spray angle of the nuclear device 2, and then adjust the collision position between the ice crystal nuclei and the water droplets. The water pump 4 provides cold water for the nozzle 1 and the nuclear device 2, the air compressor 5 provides high-pressure air for the nuclear device 2, and the fan 6 blows the snowflakes into the air.

The thermal expansion material 9 wraps the non-deformable casing 10 , the non-deformable casing 10 can constrain the thermal expansion material 9 to always be displaced in the vertical direction, and the height of the non-deformable casing 10 is greater than the maximum expansion height of the thermal expansion material 9 .

When the ambient temperature is high, the thermal expansion material 9 volume expansion reduces the angle between the nucleator 2 and the horizontal plane, and the ice crystal nuclei fly out of the nucleator from the position where the ice crystal nuclei collides with the water droplet. When the ambient temperature is low, the volume shrinkage of the thermal expansion material 9 increases the angle between the nucleator 2 and the horizontal plane, and the ice crystal nuclei fly out of the nucleator from the position where the ice crystal nuclei collides with the water droplets.

Preferably, when the thermal expansion material 9 shrinks to the minimum volume, the angle between the nuclear device 2 and the horizontal plane is not greater than 45°; when the thermal expansion material 9 expands to the maximum volume, the nuclear device 2 is still inclined upward relative to the horizontal plane, and the angle is not less than 5°.

The snowmaking machine of the present invention can sense different ambient temperatures, and automatically adjust the jet flow angle of the nucleator to change the collision position between the ice crystal nuclei and the water droplets. When the ambient temperature is high, the heat transfer rate of water droplets is slow, and it takes a long time for ice crystal nuclei to freeze. Therefore, it is necessary to increase the flight distance before collision to ensure the formation of ice crystal nuclei. When the ambient temperature is low, the freezing time of ice crystal nuclei is shorter, so the flight distance before the collision can be reduced, and the water droplets after the collision can be frozen for a longer time to improve the quality of snow. The invention can adapt to snowmaking under different temperature conditions, automatically adjusts the collision position, improves the quality of snow, and is automatic and efficient, saving manpower and material resources.
