Abstract

The invention discloses a fan tower. The tower body of the fan tower comprises a steel tower section at the upper part and a precast concrete tower section at the lower part connected with the steel tower section, wherein the precast concrete tower section is formed by splicing multiple precast concrete units. The steel-precast concrete combined fan tower disclosed by the invention overcomes the restriction in terms of manufacturing, transportation and the like of the traditional steel tower, has high economic benefits, breaks through the limitation that the height of the steel tower cannot exceed 100m, and can meet the requirement on the tower height of the current fan development.

Description

technical field [0001] The invention belongs to the field of new energy wind power and relates to a fan tower structure. Background technique [0002] The main function of the wind turbine tower is to lift the impeller to the design height to obtain greater wind energy and more stable wind speed. Relevant studies have confirmed that in the process of wind power generation, stable wind speed is an important factor for megawatt wind turbines to achieve high power. Whether on land or at sea, the wind speed is usually relatively stable at an altitude of 80-200 meters. At the same time, the size of the impeller is also a very important parameter for megawatt fan equipment. Taking a wind turbine with an average power of 2.0 to 5.0 MW as an example, the diameter of the impeller is close to 100 meters. As the need for stable wind speed and the diameter of the impeller increase, the height of the tower supporting the wind turbine also increases accordingly. In addition, according...
