Description

Technical Field

[0001] The invention relates to the technical field of supporting columns for wind turbines, in particular to an impact-resistant supporting column used inside a wind turbine body. Background Art

[0002] In the design and manufacture of wind turbines, the support column is a crucial component, especially inside the nacelle. The interior of the wind turbine nacelle needs to withstand the vibration and impact from the wind turbine blades and the generator. In order to ensure the long-term reliability and stability of the wind turbine, the use of impact-resistant support columns to improve the impact and vibration resistance of the internal structure of the nacelle has become an effective solution. The following is a detailed introduction to the impact-resistant support columns used inside wind turbines:

[0003] 1. Functions and requirements of support columns

[0004] The nacelle of a wind turbine (usually installed on top of a tower) contains core components such as the generator, gearbox, control system, brake, etc. The function of the support column is to support these important equipment, while effectively transmitting the vibration and impact force generated by the rotation of the wind turbine to the bottom of the tower to maintain the stability of the equipment inside the nacelle.

[0005] Main Requirements

[0006] High seismic resistance: During long-term operation of wind turbines, affected by factors such as wind speed changes and blade swing, periodic or random vibration shocks will occur inside the cabin. The support columns need to effectively absorb and alleviate these impact forces.

[0007] Impact resistance: The support columns should have high impact resistance to cope with possible damage caused by sudden changes in wind speed, equipment failure or external environmental shocks (such as lightning strikes, storms, etc.).

[0008] Long-term stability: The support columns must maintain their shape and performance over the long term to avoid structural failure due to fatigue or breakage.

[0009] Corrosion resistance of materials: Since wind turbines are often exposed to harsh environments (such as moisture, salt spray, etc.), the support columns need to have strong corrosion resistance to ensure their durability.

[0010] 2. Structural design of impact-resistant support columns

[0011] Impact-resistant support columns are usually made of high-strength materials, fiber-reinforced materials, and specially designed structures to improve their impact resistance. Their structural design takes into account the impact and vibration generated by the fan under different working conditions.

[0012] (1) Material selection

[0013] High-strength steel: Steel is a common material for wind turbine support columns, with good compression, tension and bending resistance. By selecting high-strength steel (such as alloy steel, steel-nickel alloy, etc.), the support column can improve its bearing capacity and impact resistance.

[0014] Fiber-reinforced composite materials: In recent years, composite materials (such as carbon fiber and glass fiber reinforced composite materials) have gradually been used in the support columns of wind turbines. These materials not only have high strength and high stiffness, but also have good fatigue resistance and impact resistance. Fiber-reinforced composite materials are also lighter in weight and can reduce the overall weight of the wind turbine.

[0015] Polymer modified materials: Some wind turbine support columns are made of polymer modified materials (such as polyester, epoxy resin, etc.). This material has strong impact resistance and is suitable for high-frequency impact environments during wind turbine operation.

[0016] (2) Structural design

[0017] Shock-absorbing structure design: The support column is often designed with a shock-absorbing system, such as elastic support and damping devices, which can effectively absorb the vibration and impact force inside the cabin. This type of design can greatly reduce equipment fatigue damage and extend the service life of the wind turbine.

[0018] Anti-impact isolation layer: In order to enhance impact resistance, a protective layer may be added to certain parts of the support column, using the material of the isolation layer to absorb part of the impact energy and reduce damage to the support column structure.

[0019] Multi-layer structure design: The support column can be designed as a multi-layer structure, using materials of different hardness and elasticity to withstand the impact force layer by layer. This not only improves the impact resistance, but also effectively reduces the dynamic load caused by mechanical shock.

[0020] 3. Working principle of impact-resistant support column

[0021] The working principle of the impact-resistant support column is mainly to disperse and absorb the impact force through its material and structural design, preventing the impact force from being directly transmitted to other components inside the cabin, thereby protecting the cabin and its internal key equipment.

[0022] Impact energy absorption: The design of the support column uses highly elastic materials and a special structural form to absorb part of the impact energy and reduce the damage to the equipment caused by sudden impact.

[0023] Vibration isolation: The support column can effectively separate and isolate external vibration sources, preventing the vibration generated by the fan itself from affecting the cabin equipment and reducing mechanical fatigue damage.

[0024] Load dispersion: Through reasonable mechanical layout, impact-resistant support columns can evenly distribute impact forces from different directions and sizes to the structure of support columns and towers, avoiding damage caused by local concentrated force.

[0025] 4. Application scenarios and advantages

[0026] (1) Application scenarios

[0027] Offshore wind turbines: Offshore wind power projects usually face stronger wind speeds, more complex climatic conditions and offshore environments. Therefore, impact-resistant support columns are particularly important in offshore wind turbines.

[0028] Wind turbines in high wind speed areas: In areas with high wind speeds, wind turbines frequently face strong impacts and vibrations, and impact-resistant support columns can provide stronger support.

[0029] Areas with high seismic requirements: In earthquake-prone areas, the impact-resistant design of the support columns can effectively resist the impact of earthquakes or other sudden dynamic loads on wind turbines.

[0030] (2) Advantages

[0031] Improve equipment reliability: By enhancing the impact resistance of the support column, it is possible to reduce wind turbine failures and downtime caused by impact and vibration, and improve the reliability and working time of wind turbines.

[0032] Extend service life: The impact resistance of the support column can reduce fatigue damage to the equipment and extend the service life of the wind turbine.

[0033] Reduced maintenance costs: Since the support column effectively absorbs and mitigates impact, the wear and tear of other key components is reduced, thereby reducing the frequency and cost of maintenance and replacement of parts.

[0034] However, the impact-resistant support columns used inside the existing wind turbine bodies cannot be used for area monitoring after networking, and some wind turbines may have problems without knowing it, which affects the overall operation of the wind turbine ring network.
