Problems solved by technology
This kind of conical tower has the advantages of safety and stability, simple structure, and beautiful appearance; however, with the increase of wind turbines and the height of the tower, the conical steel tower presents problems such as waste of materials and difficulty in transportation
For example, when the cone-shaped tower section with a bottom diameter of more than 5 meters is transported by road, it is difficult to cross the bridge due to the limitation of the net height of the bridge bottom, which restricts the geometric size and construction height of the cone-shaped steel tower; the research also shows that There are structural vibration challenges for steel cone towers exceeding 85 meters; in addition, the on-site installation of cone steel towers requires heavy and ultra-high lifting machinery for hoisting, making construction difficult

The invention belongs to the technical field of wind power generation and discloses a wind power generation tower device which comprises a frame bearing structure (1), an external maintenance structure (2) and a base (3); and the external maintenance structure (2) is connected with the frame bearing structure (1) by a connecting fitting, the bottom of the base (3) is arranged in a soil layer under the ground, and the top of the base (3) is connected with the frame bearing structure (1). The wind power generation tower device is of a novel frame structure, a main component can be made of structural steel, and a mass of plate rolling and welding working procedures can be omitted, so that the manufacture difficulty can be greatly reduced, and the wind power generation tower device can preferably take advantages of the performance of each steel material compared with the conventional conic cylinder type tower frame; and the geometric dimension of the tower frame is not limited by the transporting condition, so that the higher tower frame can be built up, the larger wind power machine set can be supported, the more wind energy can be obtained, the wind power generation tower device can be used in a place where the wind force is not strong, and the wind power generation tower device is suitable for the marine power generation machine set.
Description
technical field [0001] The invention belongs to the technical field of wind power generation, and relates to a wind power generation tower device. Background technique [0002] At present, the common wind power generation tower is generally constructed by splicing several sections of steel cones through flanges, and each section of cones is welded by steel coils. This kind of conical tower has the advantages of safety and stability, simple structure, and beautiful appearance; however, with the increase of wind turbines and the height of the tower, the conical steel tower presents problems such as waste of materials and difficulty in transportation. For example, when the cone-shaped tower section with a bottom diameter of more than 5 meters is transported by road, it is difficult to cross the bridge due to the limitation of the net height of the bridge bottom, which restricts the geometric size and construction height of the cone-shaped steel tower; the research also shows th...
