Description

Technical Field

[0001] The present invention belongs to the technical field of sports auxiliary equipment, and specifically relates to an automatic water-permeable air cushion film lubrication system used in the landing area of ​​a ski jumping platform, which is suitable for scenes such as dry snow skiing resorts and ski jumping platform air cushion protection areas. Background Art

[0002] In ski jumping training facilities, large air cushions are typically installed at the bottom of the slope to ensure safe landings for athletes. To reduce friction when athletes come into contact with the cushions, preventing issues like skin abrasions and excessive rebound from dry surfaces, aerial spraying and irrigation are commonly used to lubricate the cushions.

[0003] However, the aerial sprinkler system has many drawbacks: First, in order to keep the air cushion surface moist, the irrigation tool has low pressure and limited coverage area. Increasing the pressure will seriously waste a lot of water resources. Second, it is significantly affected by wind, resulting in uneven redirection of the sprayed water mist. It is also prone to dryness in some areas, which reduces efficiency and poses a safety hazard. Third, the sprinkler system must be turned off before the athletes set off, otherwise the water mist in the air will cause visual interference to people and affect training efficiency. Fourth, the installation structure is complex and the operation and maintenance costs are high. Therefore, there is an urgent need to develop an automatic lubrication solution for the air cushion surface with a simple structure, uniform lubrication, simple use and control, stable operation, and high efficiency and economy. Summary of the Invention

[0004] 1. Purpose of the Invention: The present invention aims to provide an automatic water-permeable ski jumping platform air cushion membrane system. Through the embedded longitudinal micro-water tube structure, water is evenly and slowly released onto the surface of the air cushion membrane, forming a continuously moist film layer, effectively reducing the surface friction coefficient, and significantly improving sports safety.

[0005] 2. Technical Solution: An automatic water-permeable ski jumping platform air cushion membrane system, characterized by comprising:

[0006] Air cushion (7): acts as a cushioning device for athletes landing, providing a safe cushioning space for athletes;

[0007] An air cushion film (1) is covered on the air cushion, and a plurality of longitudinal micro-water tubes (4) are arranged along the longitudinal direction below the air cushion film; the micro-water tubes are provided with a plurality of micro-water outlet holes (2) facing upward; the micro-water tubes and the air cushion film are connected by hot melting or sewing to form a connection point (5), so that the water holes lead to the surface of the film;

[0008] Water inlet (3): a water inlet (3) is provided at the upper end of the air cushion film, and water flows in through the micro-water pipe and slowly seeps out from the multiple micro-pores, thereby achieving uniform lubrication of the surface of the air cushion film;

[0009] Sliding water supply area: This area is located at the front of the air cushion and forms the ski jumping slope (8), which provides sliding speed for athletes and also carries the water supply system. This system can achieve flow control through gravity water supply or tap water pipe network, and has the advantages of uniform lubrication, no influence from wind, low water consumption, and environmental protection and controllability. Beneficial effects

[0010] Uniform lubrication: The design of micro water pipes and water outlet holes can achieve uniform water seepage, significantly reducing the surface friction coefficient of the air cushion film.

[0011] Strong controllability: water seepage is slow, even and controllable, and the amount of water overflowing is just the amount needed.

[0012] Structural advantages: The system has a simple structure and no longer uses aerial spraying design, making it easy to install, maintain and use.

[0013] Safety assurance: reducing the dry area on the surface of the air cushion film, effectively ensuring the landing safety of athletes and increasing the training frequency of dry land ski jumping. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. This embodiment is only an example and is not intended to limit the scope of protection of the present invention.

[0020] As shown in Figures 1 to 5, an automatic water-permeable ski jumping platform air cushion membrane system has the following specific components:

[0021] Air cushion film (1): Covers the surface of a traditional air cushion and is used to cushion the landing of a ski jump after the air cushion is inflated. It is made of plastic mesh cloth with a thickness of 0.4–1.2 mm. It has a smooth surface and good softness, which can provide athletes with a comfortable cushioning friction experience.

[0022] Ski slope (8): The ski slope (8) serves as a slope for athletes to slide before jumping. At the same time, the water inlet system (3) is installed in this area to provide water to the longitudinal micro-water pipes (4).

[0023] Air cushion (7): The air cushion (7) is installed at the end of the diving platform, at the lower part of the air cushion film (1), and is used to support the athlete's sliding after landing to ensure the athlete's safety.

[0024] Longitudinal micro-water pipes (4): These micro-water pipes are located on the back of the air cushion film, with each pipe being approximately 5-50 cm along the slope. The diameter of the micro-water pipes is approximately Φ4-Φ16 mm, and the material is PVC or silicone hose. The micro-water pipes are firmly attached to the back of the air cushion film (1) by heat pressing, gluing, or other connection methods, forming a sealed connection with the air cushion film to ensure that water does not leak from locations other than the micro-water outlet holes (2).

[0025] Micro water outlet holes (2): Multiple upward-penetrating micro water outlet holes (2) are evenly distributed on the upper end of each longitudinal micro water pipe (4), with a hole diameter of 0.2-1 mm and a spacing of about . The water holes penetrate the pipe wall and the film and directly connect to the membrane surface, allowing water to evenly seep to the upper surface of the membrane body, thereby achieving uniform lubrication of the air cushion film surface.

[0026] Water inlet system (3): This system has a water inlet (3) at the top of the air cushion membrane. Water is injected into the water pipes by connecting to the tap water network or gravity water tank. The tail ends of all water pipes are sealed to ensure that water slowly seeps out through the various water outlets during the flow. The water is transmitted in parallel through each micro-water pipe, seeping out layer by layer from top to bottom, ensuring that the entire surface of the slope membrane remains uniformly moist.

[0027] How it works: Before ski jumping training or competition, activate the water supply system (or open a gravity feed). Water flows through the inlet into the micro-tubes, gradually seeping out through the micropores to moisten the surface of the air cushion membrane. Once the membrane is moistened, the coefficient of friction decreases significantly, allowing athletes to glide smoothly after landing, effectively reducing impact and friction injuries.

[0028] Notes:

[0029] To prevent micropores from clogging, the system is recommended to be used with a water filtration device.

[0030] It is recommended to replace the membrane once a year and regularly inspect the water pipes and edge connections to ensure the normal operation of the system.

[0031] The membrane needs to be stretched during installation to ensure uniform surface tension and avoid wrinkles and bulges.

[0032] The above embodiment is a preferred structure of the present invention. Without departing from the basic principles of the present invention, engineers in the relevant technical field can make equivalent improvements or modifications according to actual needs, which should be considered within the scope of protection of the present invention.
