Abstract

The invention discloses a switching section of tower tube. The tower tube comprises a tower tube foundation and a concrete tower tube arranged on the tower tube foundation; the concrete tower tube comprises a plurality of straight tower tube sections, the transverse dimension of every two adjacent straight tower tube sections is gradually decreased from bottom to top, each straight tower tube section comprises a plurality of sub straight tower tube sections with the same transverse dimension and sequentially connected, and every two adjacent straight tower tube sections are connected through the switching section; the concrete tower tube is connected with the tower tube foundation through the straight tower tube sections; and the switching section comprises a straight pipe section and a tapered section arranged at the lower end of the straight pipe section, the tapered section is configured to gradually increase in radial dimension from top to bottom, and the taper angle of the taperedsection ranges from 60 degrees to 90 degrees. According to the switching section of the tower tube, every two adjacent straight tower tube sections are easily connected through the switching section,and the tower tube is convenient to construct.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a tower transition section. Background technique [0002] In related technologies, as the power generation efficiency of the wind turbine increases, the length of the blade becomes longer and longer, and the height and cross-sectional size of the matching wind turbine tower are also continuously increased. Due to high cost and difficult transportation, steel structure towers are difficult to meet the construction requirements of large cross-section and high towers. The prefabricated concrete tower transition section enables the economical construction of large wind turbines. During the construction of the concrete tower transition section, the individual towers are hoisted sequentially from bottom to top, and finally a complete concrete tower transition section is built. Contents of the invention [0003] The present invention aims to solve at least one of the t...
