Problems solved by technology

There are generally disengagement cracks between the foundation ring and the concrete in the foundation and the cavity formed by the collapse of the concrete around the flange under the foundation ring due to long-term wear and tear. With the increase of the cavity, the shaking of the upper fan is becoming more and more Large, seriously affecting the normal and safe operation of the fan foundation

Abstract

The invention relates to a connecting device of a tower tube and a foundation of a wind generating set. The connecting device comprises an upper connecting flange, an annular tube structure, reinforcing ribs and a lower connecting flange. The annular tube structure is arranged between the upper connecting flange and the lower connecting flange and located at the center of the tube wall of the tower tube of the wind generating set, and comprises two or more concentric circular rings. Annular tube cavities are formed by the adjacent circular rings, and grouting materials are poured into the annular tube cavities. The reinforcing ribs are arranged in the horizontal direction of the exterior of the annular tube structure. The lower portion of the annular tube structure and the lower connectingflange are pre-buried in the foundation. The annular tube structure where the grouting materials are grouted is arranged between the tower tube and the foundation of the wind generating set, and thusthe overall strength of the tube wall is improved; and the reinforcing ribs are arranged in the horizontal direction of the annular tube structure, thus connection with surrounding concrete is greatly strengthened, fatigue damage of the surrounding concrete is reduced, and the foundation is firm and reliable.

Description

technical field [0001] The invention belongs to the technical field of fan foundations, and in particular relates to a connection device between a wind turbine tower and a foundation. Background technique [0002] As a green energy, wind energy has developed rapidly in China in recent years. At present, the foundation of domestic wind turbines mostly adopts the ring foundation of gravity foundation. The gravity foundation ring foundation belongs to the traditional foundation. This technology was introduced in Europe and the United States, and was first used in the foundation of small megawatt wind turbines in China. However, with the continuous increase of the capacity of a single fan and the increase of the load of the fan, the problem of the ring foundation of the gravity foundation is gradually highlighted. There are generally disengagement cracks between the foundation ring and the concrete in the foundation and the cavity formed by the collapse of the concrete around...
