Title:
DISASSEMBLY METHOD OF TOWER TYPE WIND TURBINE GENERATOR SYSTEM
Document Type and Number:
Japanese Patent JP2022088251
Kind Code:
A
Abstract:
To provide a disassembly method of a tower type wind turbine generator system which can disassemble a tower body, which is tapered upward over the entire height, without using a large crane.SOLUTION: A load of an entire system, located above a predetermined tower body cutting height, is supported from the inner side of a tower body 1 by a jack 17 provided at an internal column 16. A worker gets in a work bench 15 installed at the outside of an outer wall of the tower body 1 to cut a middle region of a lower part of the tower body 1 over an entire periphery of the tower body 1 and remove the middle region. Then, a portion of the tower body 1 located above the middle region is lowered supported by the jack 17 to be landed in an internal cavity 3 of a lower portion of the tower body 1. Support of the upper portion of the tower body 1, removal of the middle region of the tower body 1, and lowering and landing of the upper portion of the tower body 1 are repeated to land the disassembled tower body 1 in a concentric circular form.SELECTED DRAWING: Figure 3
