Description

Granulated dry snow and its use in safety protection device of dry snow park

Technical Field

The application relates to a skiing auxiliary tool, in particular to a particle dry snow and application thereof in a safety protection device of a dry snow park.

Background

On dry snowfields, there are also "property obstacle parks". However, the prop obstacle slide way built by the current dry snow technology has a dangerous hidden danger. The danger lies in: dry snowboarding skis can only provide a ski with a near true snow, satisfactory glide. But the friction force of the dry skiing grass is too large for human bodies, equipment and clothes. Therefore, if the rider falls on the dry ski by mistake, the rider may be subjected to sudden shock and may be injured. The second hazard source is: the dry skating grass only has 50mm of buffering and damping capacity, and is far inferior to the collapse and damping of real snow.

Therefore, it is necessary to develop a safety protection device for dry snow parks.

The particle dry snow is accumulated in the dry snow park to be used as a safety protection device, on one hand, when a rider slides and successfully lands on the ground, the rider slides out of prop obstacles along the surface of the particle dry snow to finish the action; on the other hand, when the sliding hand falls from the prop obstacle, the sliding hand can fall on the protective layer accumulated by the dry particle snow, and the dry particle snow is the same as the powder snow of real snow at the moment, so that the shock absorption is provided for the falling sliding hand, and the safety of the sliding hand is ensured.

Detailed Description

The embodiment provides a granulated dry snow which is a plastic raw material and can have the density of 0.8g/cm³～1.2g/cm³。

The dry snow particle adopts plastic raw materials and can be cleaned by clear water. The density of the dry snow particles is 0.8g/cm 3-1.2 g/cm3, the wind resistance is good, and the dry snow particles are not easy to be blown away by wind.

Preferably, the plastic material is polypropylene PP material pellets having a specific gravity of 0.9g/cm 3.

More specifically, the plastic particles may have a density of 0.8g/cm³、0.9g/cm³、1.0g/cm³、1.1g/cm³Or 1.2g/cm³。

Fig. 2 is a schematic structural diagram of a granular dry snow paved on a further prop obstacle according to an embodiment of the application. Fig. 3 is a schematic structural diagram of a granular dry snow paved on a further prop obstacle according to an embodiment of the application.

As shown in fig. 1-3, the present embodiment further provides a use of the granulated dry snow in a safety protection device in a dry snow park, the dry snow park has a dry snow slideway 1 for skiing by a rider, the dry snow slideway 1 is formed by paving dry snow grass, prop obstacles 2 are further installed on the dry snow slideway 1, and the granulated dry snow 3 is stacked on the dry snow grass in an area where the rider falls down and can touch the dry snow grass, and is used as a gliding layer and a protective layer at the bottom and around each prop obstacle 2.

In this application, granule drought snow 3 piles up and is used safety device in the drought snow park, around each stage property obstacle 2, on the drought snow slide grass in the region that the smooth hand tumbles and can touch and reach, pile up granule drought snow 3 as sliding layer and protective layer, just as the powder snow of true snow, reach two effects: on one hand, when the sliding hand slides and lands successfully, the prop obstacle 2 slides out along the surface of the dry particle snow 3 to finish the action; on the other hand, when the sliding hand falls from the prop obstacle 2, the sliding hand can fall on the protective layer accumulated by the particle dry snow 3, and the particle dry snow 3 is the same as the powder snow of real snow at the moment, so that the shock absorption is provided for the falling sliding hand, and the safety of the sliding hand is ensured.

More specifically, a particle suction blower is adopted to finish the slope shape of the accumulated particle dry snow 3.

More specifically, the main body thickness of the sliding layer and the protective layer formed by the main body of the particle drought snow 3 is 30 cm.

The latest definition:

the bottom and the periphery of each prop obstacle 2 are paved by adopting the particle dry snow 3, and the skiing field of the prop obstacle 2 for ensuring the safety of a sliding hand is called as a particle dry snow park for short.

The stage property obstacle 2 park slideway paved by accumulating the particle dry snow 3 provides safety guarantee for sliding hands, particularly for sliding hands of children. The operators in the dry snow field can get rid of the trouble of sudden accidents. The slideway with the obstacle 2 is different from professional projects with too great difficulty, such as a large diving platform, air skills, snowing skills and the like, and enables public enthusiasts, particularly children, to feel pleasure of skiing and to be away from sports injury.
