[0002] With the growing global demand for renewable energy, wind power, as a clean, renewable energy source, has garnered widespread attention and application. As a key component of wind turbine systems, the design, manufacturing, storage, and transportation of wind turbine blades significantly impact the overall performance and economic viability of wind turbine systems. The efficient storage and transportation of wind turbine blades, particularly due to their large size and weight, presents a significant technical challenge.

[0003] Currently, wind turbine blades are typically stored and transported using specialized fixtures. However, these fixtures are often only suitable for wind turbine blades of specific sizes and cannot accommodate a wide range of sizes. This results in the need for different fixtures for different sizes of wind turbine blades during storage and transportation, increasing the cost and complexity of storage and transportation.
