Problems solved by technology

[0003] The main function of the tower is to support the nacelle, generator and impeller of the wind turbine. At the same time, for the better operation of the wind turbine, some tower accessories are usually set on the corresponding tower section of the tower, such as the tower platform As well as the door openings arranged on the tower, the above-mentioned tower accessories will reduce the bearing capacity of the corresponding section of the tower, which will affect the service life and safety of the tower, which is not conducive to the power generation efficiency of the wind turbine.

Abstract

The invention relates to a barrel shell, a tower barrel section and a forming method of the barrel shell. The barrel shell is used in the tower barrel section and is of a barrel-shaped structure whichis provided with a hollow chamber; the barrel shell comprises a foundation part and a reinforcing part which are circumferentially continuously distributed; the foundation part and the reinforcing part are integrally structured; and the thickness of the reinforcing part is beyond the thickness of the foundation part in the radial direction of the barrel shell. According to the barrel shell, the tower barrel section and the forming method of the barrel shell in the embodiment, tower barrel accessories can be easily arranged through the barrel shell, and moreover, the bearing capacity of the tower barrel section adopting the barrel shell is high, so that the service life of the whole tower barrel is prolonged, and the use safety of the whole tower barrel is improved; and the generation benefit of a wind-driven generation set is increased.

Description

technical field [0001] The invention relates to the technical field of wind power, in particular to a barrel section, a tower section and a forming method of the barrel section. Background technique [0002] With the development and progress of wind power technology, the technical route is constantly transforming from extensive to refined, and more lean design is becoming more and more important. As a large part of wind turbines, the tower is an important part of the unit when it is in service. [0003] The main function of the tower is to support the nacelle, generator and impeller of the wind turbine. At the same time, for the better operation of the wind turbine, some tower accessories are usually set on the corresponding tower section of the tower, such as the tower platform As well as the door openings arranged on the tower, the above-mentioned tower accessories will reduce the bearing capacity of the corresponding section of the tower, thereby affecting the service lif...
