Description

A wind turbine sleeve installation structure

Technical Field

The utility model relates to the technical field of wind power generator accessories, in particular to an installation structure of a wind power sleeve.

Background Art

A wind turbine is an electrical device that converts wind energy into mechanical work and drives the generator to rotate to output alternating current. It is mainly composed of components such as a wind wheel, a generator, a directional controller, a tower, a speed limiting safety mechanism and an energy storage device. The tower is assembled from multiple corresponding wind turbine sleeves, and multiple fastening bolts are generally used to fix two adjacent wind turbine sleeves to facilitate assembly after transportation to the destination.

When installing two wind turbine sleeves on the market, a crane is required for suspension. However, during the suspension process, the upper and lower wind turbine sleeves cannot be guided and positioned. The inability to guide and position will cause the positions of the bolt fixing holes on the two wind turbine sleeves to not correspond. The bolts cannot be used for fixing due to the mismatch in positions, and the positions need to be adjusted later, which brings inconvenience to the user. In view of this, we propose an installation structure for wind turbine sleeves.
