STRUCTURE FOR NACELLE COVER CONNECTION UNIT OF WIND POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/060370
Kind Code:
A1
Abstract:
Provided is a structure for a nacelle cover connection unit of a wind power generation device, the structure exerting excellent workability, water-tightness, and strength. An elongated first angled material (5) is secured to the surface on the inside of a nacelle cover functioning as the upper end portion (31) of a side wall panel (3). An elongated second angled material (6) is secured to the surface on the inside of the nacelle cover functioning as the lower end portion (41) of a roof panel (4). The top surface (51) of the first angled material (5) and the bottom surface (61) of the second angled material (6) are brought into contact with one another so as to secure both angled materials, thereby connecting the upper end portion (31) with the lower end portion (41) on roughly the same plane. A cover section (43) is disposed a predetermined distance away from the upper end portion (31) so as to cover same from the outside of the nacelle. The cover section (43) is integrally formed with the lower end portion (41) so as to protrude more towards the outside of the nacelle cover than the lower end portion (41). A gland packing (7) is placed between the top surface (51) and the bottom surface (61).
