Description

Technical Field

[0002] With the transformation of the global energy structure and the proposal of sustainable development goals, wind power generation, as a clean and renewable energy form, is receiving more and more attention and application. Wind power generation not only helps to reduce greenhouse gas emissions, but also can be used as a sustainable energy supply method to meet the growing energy demand.

[0003] As the core equipment of the wind power generation system, the performance and reliability of the wind turbine have a vital impact on the operating efficiency and service life of the entire system. As a key component of the wind turbine, the nacelle cover is responsible for protecting the equipment inside the nacelle from natural factors such as wind, rain, sand and dust. However, the traditional nacelle cover design usually adopts a fixed structure, which exposes many problems in practical applications.

[0004] First, the installation and maintenance process of the fixed nacelle is relatively difficult. Due to the large size and complex structure of the nacelle, a large number of bolts and other fasteners are required during installation, which makes the installation process cumbersome and time-consuming. At the same time, the nacelle needs to be disassembled and reinstalled during maintenance, which is also a time-consuming and labor-intensive task.

[0005] Secondly, the maintenance cost of fixed nacelles is high. Due to the difficulty of installation and maintenance, once the nacelle fails or is damaged, it often takes a lot of time and manpower to repair or replace it, which not only increases the maintenance cost, but also may affect the normal operation of the wind turbine.
