项目背景

To protect the common ecological environment of mankind and achieve green and sustainable development, China vigorously promotes the development of renewable energy. The development and utilization of wind energy , as a green and clean energy source, plays an important role in increasing energy supply and adjusting energy structure.The construction of wind farms is always where investment of national energy is focused on. A wind farm contains dozens of wind turbines, and the installation & assembly of each wind turbine must be completed with the assistance of a heavy duty crane. The operation procedure includes: lifting and installation of tower sections, nacelle & electric motor, and rotor. Attaching the rotor to the nacelle is performed at a height of more than 80 meters makes it difficult to operate with high risk to adjusting the rotor until the bolts on the hub may go into the bolt bores on the nacelle with a crane.

技术要求

The following requirements shall be met in the research and development of the technology and device for alignment of the wind turbine rotor in the air:
1. The alignment shall have guiding and positioning functionality. The alignment device shall be able to adjust the position of the rotor and guide the rotor to align with the nacelle. The alignment process must safe and efficient.
2. After the positioning is completed, the alignment device should be detached from the impeller or engine room and reusable by simple operation.
3. The alignment device should be simple in structure and light in weight, so as to reduce the influence on the weight of the object to be lifted (the total weight is less than 1500kg/set).
4. The alignment device should be commercialization feasible (cost less than RMB 100000 yuan / set).

参考信息

1.A video about installation and assembly of a wind turbine.
2.Main technical parameters of Jinfeng 2.5MW wind turbine.
