Abstract

The invention discloses a tower foundation of a wind generating set and relates to the technical field of wind power generation, aiming to solve the problems that an existing tower foundation cannot meet requirements on anchoring at two ends of the bottom of a prestressed cable in a prestressed structure and maintenance and replacement of other components in the prestressed structure are not facilitated. The tower foundation comprises a hollow tower foundation body, a cover plate is arranged at the top of the tower foundation body, and a manhole is formed in the cover plate; ring beams used for supporting the cover plate are arranged on the inner wall of the tower foundation body; prestressed cable channels are arranged in the tower foundation body and penetrate the side wall of the tower foundation body, one ends of the prestressed cable channels are communicated with the top of the tower foundation body, and the other ends of the prestressed cable channels are communicated with the hollow part of the tower foundation body. The bottom of the tower foundation body is connected with a concrete cushion which is located on the surface of the foundation.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a tower foundation of a wind power generating set. Background technique [0002] The wind turbine is referred to as the fan for short, and the fan mainly includes impellers, generators, towers and other components, and the towers are used to support the impellers, generators and other components on it. The tower is usually set on the foundation of the wind turbine and fixedly connected with the tower foundation. [0003] The existing tower foundations are all solid foundations. However, prefabricated concrete towers usually adopt a prestressed structure, and the two ends of the bottom of the prestressed cables in the prestressed structure need to be anchored, and the anchored ends of the prestressed cables need to be stretched and other operations. Since the foundation of the tower in the existing wind power generating set is a solid structure, the solid foundatio...
