Embodiment Construction

[0013] A hexagonal fan tower structure, which includes a tower main body 10, a fan impeller 20 is arranged on the tower main body 10, the tower main body 10 is a truss structure, and the tower main body 10 includes a plurality of support columns 2 and Reinforcing connecting rods 3 connected between adjacent supporting columns 2; the number of supporting columns 2 is six, and the six supporting columns 2 are arranged in a symmetrical hexagonal shape; the supporting columns 2 are composed of multi-section supporting connecting rods 21 through bolts Riveted or welded.

[0014] In order to enhance the rigidity and stability of the tower, the reinforcing connecting rods 3 are connected between the adjacent support columns 2 in pairs; or the reinforcing connecting rods 3 are connected between the adjacent supporting columns 2 in a triangular shape.

[0015] When the present invention is used in offshore wind power generators, the bottom foundations of multiple support columns 2 are ...

Abstract

The invention discloses a hexagonal tower structure of a wind driven generator, which is characterized by comprising a tower body. An impeller of the wind driven generator is arranged on the tower body, the tower body has a truss structure and comprises six supporting posts and reinforcing links respectively connected among adjacent supporting posts, the six supporting posts are in symmetrically hexagonal arrangement, and each supporting post consists of multiple supporting link sections which are riveted by bolts or are welded mutually. The hexagonal tower structure has the advantages that the hexagonal tower structure is attractive and is convenient to transport, manufacturing cost thereof is lower than that of a steel made cylinder, while strength thereof is strong enough to support the large wind driven generator. Besides, due to the fact that the truss structure has wide gaps, small windward area and lower wind load in horizontal direction, production cost for foundation can be reduced effectively by six foundation piles offshore. Besides, the hexagonal tower structure is lighter in weight and convenient to be hoisted as compared with the conventional cylinder.

Description

【Technical field】 [0001] The invention relates to a hexagonal fan tower structure. 【Background technique】 [0002] At present, most wind turbine tower structures use steel towers, which are heavy and expensive. At present, low-power wind turbines can no longer meet the needs of the market. With the development of large-megawatt (>5MW) wind turbines, the size and shape of steel towers are increasing, resulting in high cost and difficult transportation. And so on a series of questions. [0003] Due to the increasing saturation of onshore wind power generators, offshore wind power is imperative, and offshore wind resources are abundant. However, at this stage, offshore wind power is still in the prototype test stage around the world. Offshore wind turbines are heavy and expensive to manufacture. 【Content of invention】 [0004] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a design for high-power wind turbines, which ha...
