Problems solved by technology

[0004] Snowmaking quality requirements are usually related to snow density. The existing snow density detection methods often directly detect the volume and weight of snow for calculation, which has the disadvantage of large errors. Therefore, it is necessary to design a more convenient, fast and accurate method. Method for detecting snow density

Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with specific embodiments.

[0029] In specific implementation: a snow density detection method, the main point of which is that when detecting the snow density, a predetermined volume of snow is intercepted from top to bottom, heated and melted, and then the weight is detected, and then the weight is divided by the volume to obtain the snow density.

[0030] This is because the snowflakes are in a hexagonal state with extremely large edges, and the detection weight after the container is directly contained is likely to cause a large detection error due to the friction between the container wall and the snowflake. Therefore, the method of detecting the snow weight after heating and melting can be extremely The detection accuracy is greatly improved, and the detection calculation of snow density is ensured to be more accurate.

[0031] Specifically, in this embodiment, when detecting the snow ...

Abstract

The invention discloses a snow density detection method which is characterized in that when the snow density is detected, a section of snow with a preset volume is cut from top to bottom, the snow is heated and melted, then the weight of the snow is detected, and then the snow density is obtained by dividing the weight by the volume. The method has the advantage that the snow density parameter can be detected more conveniently, quickly and accurately.

Description

technical field [0001] The invention relates to the technical field of snow making machine testing equipment, in particular to a snow density detection method. Background technique [0002] A snow gun is a kind of artificial snow making equipment, which is usually widely used in places such as ski resorts and ice skating rinks. Snow making machines are usually used in a low temperature environment. The principle of snow making is to spray high-pressure water and high-pressure air through a nuclear device to form snow cores with small particle size, and then spray high-pressure water from the nozzles and collide with the snow cores. Combine to form snowflakes to make snow. [0003] In order to ensure that the quality and performance of snow guns are up to standard, performance testing is required to check whether the product is qualified and feedback design improvements. The applicant has applied for a patent CN202110464712.9 and disclosed a method for detecting the atomiza...
