Problems solved by technology

The connection between the pieces will inevitably lead to seams, which will adversely affect the airtightness of the nacelle cover
It is difficult to process the connections between the pieces of the existing nacelle cover, which may easily cause product defects; or the sealing effect is poor, and water seepage in the nacelle cannot be effectively avoided

Abstract

The invention relates to the field of application of wind driven generator equipment, in particular to a sealing structure of a wind power cabin cover. The sealing structure comprises a bent first flange and a second flange connected with the first flange. The first flange is provided with a first bending part. The second flange comprises a second flange main body and a fork plate connected with the second flange main body. The fork plate is provided with a second bending part, and a fork gap is formed between the second bending part and the second flange main body. The first bending part extends into the fork gap and is connected with the second bending part. According to the sealing structure, after the first bending part extends into the fork gap and is connected with the second bending part, the fork gap is transversely expanded outwards relative to the flange main bodies, the space between the first flange and the second flange is expanded, a necessary operation space is formed between the second flange and the first flange and is provided for mounting and operating personnel, the number of connecting sheet bodies of the cabin cover is effectively reduced, the requirement for reducing splicing seams can be met, and the sealing performance is enhanced while the connecting and machining difficulty among the sheet bodies of the cabin cover is reduced.

Description

technical field [0001] The invention relates to the application field of wind power generator equipment, in particular to a sealing structure of a wind power generator nacelle cover. Background technique [0002] The nacelle cover is used to protect the components in the cabin from being directly exposed to the complex and harsh external environment, to ensure the normal operation of the unit, to prolong the service life of the unit, to reduce the running resistance of the fan, and to provide the necessary operating space for the installer and operator. Wind turbines have been eroded by wind, rain, snow, ultraviolet rays, and salt spray for a long time, so there are relatively high requirements for the sealing of the nacelle cover. [0003] However, due to its larger size and on-site assembly requirements, the nacelle cover is generally divided into several pieces, each piece is produced independently, and finally assembled into a whole. The connection between the sheets wi...
