Embodiment 1

[0045] The tower frame of the wind power generator is formed by connecting multiple tower sections 3 , and the tower section 3 is formed by connecting and surrounding multiple tower plates 1 in sequence. One solution is that the tower plate 1 adopts an integrated structure. When the integral structure is adopted, the tower plate 1 is integrally formed so that both sides are bent into flanges, and there are holes on which two adjacent tower plates 1 can be connected together by rivets 5 or bolt assemblies 4, Two adjacent tower plates 1 are then connected through the above-mentioned method. The tower plate 1 is only bent once.

[0046] Each tower section 3 is surrounded by 4, 6, 8 or more tower plates 1 from end to end. The number of tower plates 1 is not specifically limited. The specific number of tower plates 1 is mainly determined by each The size of each tower plate 1 and the consideration of transportation are determined.

Embodiment 2

[0049] The tower frame of the wind power generator is formed by connecting multiple tower sections 3 , and the tower section 3 is formed by connecting and surrounding multiple tower plates 1 in sequence. The tower plate 1 adopts a split structure. The tower plate 1 of this structure includes a tower plate body 8 and angular connecting plates 2 arranged on both sides of the body. Each angled connecting plate 2 is a bent structure, and the angled connecting plate 2 is provided with a through hole, and the adjacent angular connecting plates 2 of two adjacent tower plates 1 are connected by means of rivets 5 or bolt assemblies 4 . The other side of the angled connecting plate 2 is connected with the tower plate body 8 through a rivet 5 or a bolt assembly 4 . The tower plate 1 is only bent once.

Embodiment 3

[0053] A method for assembling a tower of a wind power generator, comprising the following steps:

[0054] 1. At least two tower plates 1 are assembled around the connection from end to end to form a tower section 3. Due to the needs of production and application, each tower section 3 often includes multiple tower plates 1 in actual use, such as 4 or 6 , 8 or more tower plates 1 end to end, the number of tower plates 1 is not specifically limited, and the specific number is mainly determined by the size of each tower plate 1 after splitting and the consideration of transportation.

[0055] 2. Adjacent tower plates 1 are connected to each other through connecting plates arranged on both sides of each tower plate 1 , and two adjacent connecting plates are connected by means of rivets 5 or bolt assemblies 4 . Specifically, the tower plate 1 can adopt an integrated structure. When the integrated structure is adopted, the tower plate 1 is integrally formed so that both sides are be...

Abstract

The invention relates to the technical field of wind power generation, in particular to a wind driven generator tower which has technical scheme as follows: the wind driven generator tower is formed by connecting a plurality of tower sections, and each tower section is formed by sequentially connecting and winding a plurality of tower frames. One technical scheme is as follows: two sides of each tower frame plate are bent into connecting flanges which are provided with holes capable of ensuring that two adjacent tower frame plates are connected together by using bolt assemblies or pulling rivets; and the other technical scheme is as follows: each tower frame plate comprises a tower frame plate body and angular connection plates arranged at two sides of the tower frame plate body. The invention has the advantage that a detachable structure is adopted in each tower section, and the tower sections with huge volumes are dismantled into a plurality of tower frame plates with same shapes, thus the tower frame plates are convenient for transportation.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power generator tower and its transportation and assembly methods. Background technique [0002] In the field of wind power technology, for the production of wind turbine towers, the common method is to divide the tower into several tower sections, after the factory is finished, transport them to the installation site, and then assemble and weld them into towers. However, as the power of wind turbines increases, the size and weight of the towers also increase, which brings great difficulties to transportation. If it is still manufactured in the factory and then transported to the installation site, the transportation will be a very troublesome and expensive matter, especially for overseas contracted projects, it will take dozens of 70-80 meters high and 4 meters in diameter. When the tower is shipped overseas, because the size will be greater than the tonnag...
