Description

Technical Field

[0001] The present application relates to the technical field of artificial skiing sports equipment, and in particular to a granular dry snow landing slope ski jumping platform. Background Art

[0002] Skiing is to take off from the ski jump, show off skills in the air, and then return to the snow surface of the landing slope to land safely and glide to the end. The ski jump is composed of a starting platform, an acceleration slide, a take-off platform, a landing slope and a glide deceleration stop area. Skiers wear skis and rely only on their own physical strength to go down from the starting platform, gain speed on the acceleration slide, take off from the take-off platform, show off skills in the air, and then return to the snow surface of the landing slope, land safely, and finally glide to the end.

[0003] Skiing is dangerous, expensive, has a short snow season, inconvenient transportation, and low training efficiency. In order to improve the environment for skiing, people made fake snow out of plastic and named it: dry snow. There are two types of ski jumping platforms: real snow jumping platforms and dry snow jumping platforms. Real snow jumping platforms can only be used for 120 days in winter every year, and there is no snow in the warm spring, summer and autumn. The landing slope of the real snow jumping platform is an ice-like snow landing slope, without cushioning and shock absorption, which is very dangerous and accidents occur frequently. The existing dry snow jumping platform is an air cushion water slide. The water slide can only slide, not slide: it is impossible to maintain body balance, choose the sliding route, control the sliding direction, control the sliding speed, practice landing, and even more impossible to practice sliding and decelerating to the end. In addition, the air cushion water slide is completely wet and can only be used for 120 days in summer. It is unbearable to train in the cold and wet autumn, winter and spring. In addition, the humid and moldy environment where the jumper is located is not good for health. Summary of the invention

[0006] By adopting the above technical solution, no matter what posture the flyer makes when landing, the granular dry snow landing slope can provide all-round safety protection for him. The accumulation angle of the granular dry snow is designed to be the same as the slope of the landing area. When the flyer lands, the local slope will be damaged, but the particles above the damaged slope will roll down and automatically fill the damaged part. The landing slope will be repaired with the slope of the particle accumulation angle. At the same time, the granular dry snow lifting device will lift the granular dry snow that rolls to the bottom of the granular leak plate to the slope inflection point knuckle for replenishment.

[0013] Optionally, the second conveying mechanism is a particle screw conveyor and is arranged vertically.

[0014] By adopting the above technical solution and the intermittent conveying characteristics of the granular screw conveyor, it is possible to ensure the recycling of granular dry snow, reduce manual intervention, and improve the degree of automation of the entire granular dry snow lifting device.

[0017] Optionally, the inclination angle of the first conveying mechanism is consistent with the slope of the landing area.

[0018] By adopting the above technical solution, the friction and resistance in the transportation process are reduced, thereby reducing energy consumption and improving transportation efficiency. At the same time, it also helps to reduce the breakage of particles in the transportation process and maintain the integrity of the granular dry snow.

[0019] Optionally, the thickness of the granular dry snow on the landing area is 20-100 cm.

[0034] The following will be combined with the attached Figures 1 to 3 , the technical solutions in the embodiments of the present application are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0035] The present application embodiment discloses a granular dry snow landing slope ski jumping platform. Figure 1The granular dry snow landing slope ski jumping platform (hereinafter referred to as the granular jumping platform) includes an acceleration slide 1, a take-off platform 2, a landing slope 3 and a deceleration platform 4. A starting platform is provided in front of the acceleration slide 1. The skier accelerates and slides on the acceleration slide 1. The take-off platform 2 has a take-off elevation angle. The skier with sufficient speed can take advantage of the momentum to take off and fly in the air, and finally land accurately on the landing slope 3, and decelerate and slide to the end point on the deceleration platform 4.

[0036] The acceleration slide 1 and the take-off platform 2 are both paved with sliding dry snow. The landing slope 3 and the deceleration platform 4 are paved with granular dry snow 35, so that the sliding conditions of the landing slope 3 and the deceleration platform 4 are the same. The sliding dry snow is used to pave the sliding snow track, but cannot be used to pave the landing slope 3 of the ski jump, and cannot provide safety protection for the lander. Granular dry snow 35 is used to pave the landing slope 3 of the ski jump. Granular dry snow 35 is expensive and requires a lot of maintenance work, so it is generally not used to pave the sliding snow track.

[0037] Reference Figure 2 and Figure 3 The landing slope 3 includes a slope body 31, a bottom support structure 32, a waterproof board 33, a ski carpet 34 and granular dry snow 35 which are sequentially laid on the slope surface of the slope body 31. The bottom support structure 32 is constructed of a steel structure or other hard materials to form a basic slope shape and provide a stable support. The thickness of the ski carpet 34 is about 15 mm. The slope body 31 includes a platform area 31b located at the inflection point knuckle 31a of the slope surface, a platform area 31b on the side of the inflection point knuckle 31a facing the take-off platform 2, and a landing area 31c on the side of the inflection point knuckle 31a facing the deceleration platform 4. The thickness of the granular dry snow 35 on the landing area 31c is 20 to 100 cm. The stacking angle of the granular dry snow 35 is designed to be the same as the slope of the landing area 31c, and the slope is 20 to 40 degrees.

[0038] The slope of the granular dry snow 35 in the landing area 31c is 20-40 degrees, which can provide sliding support for the lander. In one embodiment, the slope is 38 degrees, which meets the real snow landing slope 3 standard of the International Ski Federation FIS. The accumulation thickness of the granular dry snow 35 on the deceleration platform 4 is 5-10 cm, providing a suitable deceleration buffer area to ensure that the skier can safely decelerate when the skier ends the slide. It can ensure that the granular dry snow 35 has a certain elasticity and buffering capacity to reduce the impact that the skier may receive during the deceleration process, and can also maintain the continuity and controllability of the slide to avoid the ski board from getting stuck or losing control due to too thick granules.

[0039] When the lander successfully lands on the particle landing slope 3, he will slide down the landing area 31c in a gliding manner. When the landing fails on the particle landing slope 3, the lander will hit the particle landing slope 3, buffer and then stop. Every part of the lander's body will be buffered and shock-absorbed by the particles to obtain safety protection. Regardless of the posture of the flyer when landing, the particle landing slope 3 can provide all-round safety protection for the lander. When trying new or difficult movements, the thickness of the accumulated particle dry snow 35 can be increased to ensure safety.

[0040] When the flyer lands, the slope surface will be damaged to a certain extent. After the lander leaves the landing slope 3, the granular dry snow 35 above will roll down, automatically fill the collapse, and restore the slope of the landing slope 3 according to the accumulation angle.

[0041] The pellet ski jump does not need water spraying to help it slide, and can be used all year round. Especially in winter, the pellet ski jump completely avoids the landing danger of the real snow ski jump. The pellet ski jump can be built indoors or outdoors, and can also be built in cold and tropical areas. It is not afraid of wind, sand, rain, snow, freezing and exposure. The pellet ski jump is guaranteed to be used for 8 years after it is built once. The pellet ski jump has low energy consumption and is environmentally friendly; the pellet ski jump is easy to maintain.

[0042] Reference Figure 2 A granular drain plate 5 is provided at the root of the slope 31, and the granular drain plate 5 is covered by the granular dry snow 35. A granular dry snow lifting device 6 is buried at the bottom of the slope 31 of the landing area 31c, one end of the granular dry snow lifting device 6 is located below the granular drain plate 5, and the other end extends to the slope inflection point knuckle 31a, which is used to recover the granular dry snow 35 leaking from the granular drain plate 5 and overflow it to the platform area 31b and the landing area 31c slope.

[0043] Specifically, the granular dry snow lifting device 6 includes a first storage box 61, a first conveying mechanism 62, a second storage box 63 and a second conveying mechanism 64. The first storage box 61 is located below the granular leaking plate 5, and the granular dry snow 35 pushed downhill by the lander will leak through the granular leaking plate 5 into the first storage box 61 below for recovery. The second storage box 63 is close to the slope inflection point knuckle31a and is located above the first storage box 61. The input end of the first conveying mechanism 62 is located at the lower position and is connected to the first storage box 61, and the output end is located at the upper position and is used to convey the granular dry snow 35 to the second storage box 63; the input end of the second conveying mechanism 64 is connected to the second storage box 63, and the output end extends to the slope inflection point knuckle31a.

[0044] The first storage box 61 collects the granular dry snow 35 leaking from the granular leaking plate 5, and transports the granules to the second storage box 63 through the first conveying mechanism 62. Finally, the second conveying mechanism 64 pushes the granular dry snow 35 onto the landing slope 3 platform in a spring manner and overflows, replenishing the granular dry snow 35 in the platform area 31b and the landing area 31c. Not only is the use efficiency of the granular dry snow 35 improved, the waste of resources is reduced, but also the uniformity of the surface of the platform and the consistency of the sliding conditions are ensured, thereby improving the safety of skiers and the durability of the platform. The granular dry snow lifting device 6 recycles and reuses the fallen granular dry snow 35, ensuring the continuous maintenance and stability of the granular dry snow 35 on the surface of the landing slope 3.

[0045] In this embodiment, the first conveying mechanism 62 is a particle screw conveyor, and the conveying direction is inclined upward, which not only improves the recovery efficiency, but also reduces the overall space occupied by the particle recovery and lifting device, reduces the demand for space, reduces the impact of the burial of the particle recovery and lifting device on the slope 31, and improves the strength and stability of the slope 31. Due to the intermittent conveying characteristics of the particle screw conveyor, it can ensure the continuous recovery and reuse of the particle dry snow 35, reduce manual intervention, and improve the degree of automation of the entire particle dry snow lifting device 6.

[0046] The inclination angle of the first conveying mechanism 62 is consistent with the slope of the landing area 31c, that is, consistent with the accumulation angle of the granular dry snow 35, so that the granular dry snow 35 can move more smoothly during the conveying process, reducing the friction and resistance during the conveying process, thereby reducing energy consumption and improving the conveying efficiency. At the same time, it also helps to reduce the damage of the particles during the conveying process and maintain the integrity of the granular dry snow 35, which is very important for maintaining the quality of the platform surface.

[0047] The second conveying mechanism 64 is a granular screw conveyor and is arranged vertically so that the granular dry snow 35 overflows in a spring-like manner, effectively replenishing the granular dry snow 35 in the platform area 31b and the landing area 31c, and maintaining the continuity and consistency of the platform surface. At the same time, the vertical conveying method reduces the friction and resistance during the conveying process, reduces energy consumption, and improves the conveying efficiency. In addition, the spring-like overflow method helps the granular dry snow 35 to naturally backfill and repair the landing slope 3 according to the accumulation angle, reducing the intervention of external thrust.

[0048] The second conveying mechanism 64 pushes the particles in the second storage box 63 to the inflection point knuckle 31a of the slope in a spring-like manner and overflows. The overflowed particles are divided into two paths, one path replenishes the particles around the take-off platform 2, that is, the platform area 31b; the other path rolls down along the landing area 31c, backfills and repairs the landing slope 3 according to the accumulation angle of the particle dry snow 35. The particle dry snow lifting device 6 is buried under the landing slope 3, which has good concealment, making it difficult for the lander, referee, coach and spectator to detect, reducing the visual interference to the skiers, referees, coaches and spectators, and ensuring the aesthetics and environmental adaptability of the platform; at the same time, the concealed mechanical facilities will not cause safety hazards to the lander.
