Problems solved by technology

For this section of the shell, the steel plate near the bottom has a large load-bearing capacity, while the load-bearing capacity near the upper part is small, resulting in a lot of waste of steel at the top
If this section of shell is made longer, the waste will be more serious

Embodiment Construction

[0033] The present invention will be further described below in conjunction with specific examples.

[0034] Such as Figure 1 to Figure 7 As shown, the polygonal wind power tower described in this embodiment includes at least two tower sections, and the horizontal cross-section of each tower section is a polygonal structure. Due to the polygonal structure, the tower does not need a coiling machine Production can be changed to a bending machine; two tower sections are connected by welded flanges 1 (made of ring forgings or welded parts), and bolts 2 are used to connect the flanges 1 of the two tower sections Fixing is carried out, and then the tower sections are connected into a whole, and longitudinal ribs 3 are welded on the flange 1 for reinforcement, and the longitudinal ribs 3 are also welded together with corresponding tower sections. In this way, the horizontal plane of the tower does not have welds or welds are reinforced, thereby avoiding the weak phenomenon. And be...

Abstract

The invention discloses a polygonal wind power tower and a manufacturing method thereof. The polygonal wind power tower comprises at least two tower sections. The horizontal cross section of each tower section is of a polygonal structure. Every two tower sections are in butt joint through a welded flange plate, each flange plate for connecting the two corresponding tower sections is fixed through bolts, and therefore the tower sections are connected into a whole. Longitudinal reinforcing ribs are further welded to the flange plates for reinforcement and welded to the corresponding tower sections together. By the adoption of the polygonal wind power tower and the manufacturing method, the tower does not need to be produced through a veneer reeling machine and can be splice-welded through steel plates or manufactured through a bending machine, materials can be fully used, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of wind power towers, in particular to a polygonal wind power tower and a manufacturing method thereof. Background technique [0002] It is well known in the industry that most of the towers of traditional large-scale wind turbines adopt a conical structure, and the horizontal cross-section of the tower shell is circular. Due to the conical structure, the tower must be divided into many small sections, and each section must be produced by a plate rolling machine, which results in a large amount of equipment investment. At the same time, the coiling length of the coiling machine is limited, and the coiling length of most coiling machines does not exceed 3 meters, so to make a tower with a length of tens of meters, it is necessary to produce small sections of conical shells, and then Then weld these small pieces together. This results in a huge welding workload. [0003] Since the tower is composed of many ...
