Abstract

The invention discloses a tower drum used for a wind driven generator. The tower drum comprises a tower drum foundation, a tower drum body and an adapter, the tower drum body is of a concrete structure and comprises a plurality of tower drum segments which are sequentially connected in the vertical direction, each tower drum segment comprises at least one assembling tower drum segment and at least one whole ring tower drum segment, each assembling tower drum segment is arranged on the tower drum foundation, each whole ring tower drum segment is arranged on the corresponding assembling tower drum segment, and each assembling tower drum segment comprises a plurality of tower pieces sequentially connected end to end in the circumferential direction; each whole ring tower drum segment is an integrally-formed annular part; the adapter is a metal part and arranged on the top of the tower drum body. According to the tower drum, leveling construction of the tower drum structure is facilitated, piece-by-piece prefabricating of the large-size tower drum segments in the conical tower drum structure facilitates transportation and lifting, and whole-ring prefabricating of the small-size tower drum segments can reduce construction cost and improve the construction efficiency; the adapter is arranged at the top end of the tower drum, the large weight and the large torque of the wind driven generator can be borne, and therefore safety of the tower drum is ensured..

Description

technical field [0001] The invention relates to the technical equipment field of wind power generation, in particular to a tower used for a wind power generator. Background technique [0002] As the power generation efficiency of wind turbines increases, the blades of wind turbines are getting longer and longer, and the height and cross-sectional size of the matching wind turbine towers are also increasing. Due to high cost and difficult transportation, steel structure towers are difficult to meet the construction requirements of large cross-section and high towers. Prefabricated concrete towers, which enable the economical construction of large wind turbines, have received much attention. Due to the limitations of transportation conditions and prefabrication processing conditions, a single large-section tower is often assembled on site by multiple arc-shaped tubes. Then the assembled individual towers are hoisted sequentially from bottom to top, and finally built into a c...
