MOUNTING METHOD OF A NACELLE IN AN UPPER PART OF A TOWER Russian patent published in 2020 - IPC F03D13/10 

FIELD: power engineering.

SUBSTANCE: invention relates to a method of mounting a nacelle of a wind power plant. Proposed method consists in mounting carcass 10 on top of turret 1 mounted on foundation. Cables 21 from nacelle M are attached to carcass pulleys and their ends are connected to lifting hook 24 of crane C2. Hook 24 is lifted with the help of crane C2, cables 21 are tightened through all pulleys and nacelle M is lifted. In process of lifting, motion of cables 21 is fixed on the foundation in front of pulley. In the fixed state, hook 24 is changed in the direction opposite to the tension of cables 21. Then, movement of cables 21 is fixed. By means of crane C2 hook 24 is lifted. Nacelle M is raised higher. Reproducing the process of changing connection and subsequent production process with further lifting nacelle M. Gondola M is brought into frame 10. Further, nacelle M is suspended in carcass 10 and, at the same time, disconnected from ropes 21. Suspended in carcass 10 nacelle M is moved to upper part of tower 1 and mounting is performed.

EFFECT: invention is aimed at improvement of productivity.
