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 assembling tower drum segments and whole ring tower drum segments, 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; each tower piece is provided with connecting side walls adjacent to other tower pieces, the connecting side walls of every two adjacent tower pieces are spaced, two separating and blocking parts are arranged between the connecting side walls of every two adjacent tower pieces, and are spaced in the radial direction of the tower drum, and a grouting gap with the closed periphery is defined by two separating and blocking parts and the corresponding connecting side walls on the two sides and is filled with grouting materials; the adapter is arranged on the top of the tower drum body. According to the tower drum, grouting seal performance and the pouring quality of prefabricated tower pieces on the vertical joint are ensured, and the forming quality of the assembling tower drum segments is improved.
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...
