Abstract

The invention aims to provide a scalable hubcap with a connecting rod hinge assembly and a working method thereof. Thescalable hubcap is characterized in that the scalable hubcap comprises a tower drum, a cabin cover, a fan blade rotator, three blades and three hubcap suites, each hubcap suite is composed of an openable panel subelement, a movable subcomponent, a transmission structure assembly and four elevators, each elevator is provided with a traction rope and a rope clip; the whole sealing cover is used for the wind driven generator rotator, separation and folding of the rotator covers corresponding to the blades are achieved through the connecting rod hinge assemblies, so that the hubcap is opened and moves in the axial direction of the blades, an operation platform is provided for maintenance and repair of the blades, and the hubcap can be opened in a horizontal telescopic mode and moves in the chordwise direction of the blades; the hubcap extends atthe pre-bending part of the blade and smoothly penetrates through the wider position area of the blade, so that the operation area is increased, the normal operation of the fan can be quickly recovered after use, the maintenance platform does not need to be disassembled and carried, and the the hubcap is convenient, efficient, safe and reliable to use.

Description

technical field [0001] The invention relates to the field of wind power generators, in particular to a scalable hub cover with a connecting rod hinge assembly and a working method thereof. Background technique [0002] At present, wind power generation is a kind of green, low-carbon and highly competitive renewable energy. At home and abroad, wind energy is regarded as a clean and renewable energy that is vigorously developed and continuously utilized. However, with the continuous operation of wind turbines in harsh environments, The blades are under high-load operation for a long time, and the blades are easily eroded and damaged by natural environments such as wind and sand, rain, and salt spray. Therefore, the maintenance and repair of blades is one of the important tasks of the wind farm. For this reason, wind farm staff often use Hanging basket or platform device for maintenance and repair. However, the existing maintenance platform is bulky and complex in structure. A...
