Measuring device used for measuring hardness of ice-shaped snow surface

Abstract

The invention provides a measuring device used for measuring the hardness of an ice-shaped snow surface. The measuring device comprises a sliding rail, a probe and a pressure sensor. The probe is arranged to move linearly along the sliding rail. The pressure sensor is arranged on the probe and used for measuring the hardness of the ice-shaped snow surface. According to the measuring device, the probe linearly moves along the sliding rail, the probe is pressed into the ice-shaped snow surface, the pressure borne by the probe when the probe is pressed into the snow surface is measured through the pressure sensor to serve as the hardness of the snow surface, operation is easy, the measuring device is suitable for ice-shaped snow surfaces with various gradients and thicknesses, and scientificmeasurement of the hardness of the ice-shaped snow surface is achieved.

Description

technical field [0001] The invention relates to the field of snow surface characteristic detection, in particular to a measuring device for measuring the hardness of ice-like snow surface. Background technique [0002] In alpine skiing competitions, in order to ensure a maximum sliding speed of 130-140 km / h, there are strict requirements on the hardness of the snow track. The surface of the snow track must remain in a crystalline state, similar to the ice surface, which is called ice-like snow. Ice-like snow can reduce the friction between the snowboard and the snow track. Such a snow track is not easy to be damaged. When the athletes turn at high speed, the surface of the snow track is guaranteed to be smooth and smooth, so that no matter how many times the players appear on the field, the state of the snow track can be guaranteed. All are relatively perfect. Therefore, the ice snow track is an important support to ensure the fairness and safety of winter skiing events. A...

Problems solved by technology

However, whether the track hardness, bearing capacity, and ice and snow strength are qualified can only be tested by visual inspection or manual experience judgment, which seriously affects the scientificity and controllability of the key parameter of hardness in the track production process.

[0003] At present, although the types of hardness measuring instruments are relatively complicated, these hardness testing equipment are generally suitable for measuring the surface hardness of traditional materials such as metal alloys, plastics, and rubber, and are not suitable for measuring the hardness of ice-like snow at different depths.
