For solving the problems referred to above, this utility model adopts the technical scheme that: a kind of split blade type wind turbine tower, Described split blade type wind turbine tower includes multiple tower shell ring being sequentially overlapped, and described tower shell ring includes at least two Block can mutually be spliced into the tower shell ring sheet of described tower shell ring, for connecting the connection member of described tower shell ring sheet And securing member, the both sides of described tower shell ring sheet have multiple connecting hole, vertically arrange, described connection Parts have multiple first installing hole and multiple second installing hole, and the plurality of first installing hole and multiple second is installed The position in hole is corresponding with multiple connecting holes of adjacent tower shell ring sheet respectively, and by securing member by tower shell ring sheet It is spliced into tower shell ring.
Preferably, described tower shell ring includes three pieces or the four pieces tower cylinders that can mutually be spliced into described tower shell ring Nodal plate.
Preferably, described connection member includes that interior connection sheet and outer connection sheet, interior connection sheet and outer connection sheet all have There are multiple first installing hole and multiple second installing hole.
Preferably, the outer surface of described interior connection sheet is close to the inner surface of described tower shell ring, described outer connection sheet Inner surface be close to the outer surface of described tower shell ring.
Preferably, the inner surface of described interior connection sheet and the outer surface of described outer connection sheet are plane.
Preferably, the outer surface of described interior connection sheet and the inner surface of described outer connection sheet are cambered surface.
The beneficial effects of the utility model are: solve the transportation problem of wind power plant major diameter pylon, structure Simple and be easily installed.The height of wind power plant can be improved, to obtain more preferable wind energy, obtain more preferable warp Ji benefit.
Below with reference to accompanying drawing, the technique effect of design, concrete structure and the generation of the present invention is described further, To be fully understood from the purpose of this utility model, feature and effect.

Detailed description of the invention
Fig. 1-Fig. 9 shows a kind of the most concrete real of the split blade type wind turbine tower that this utility model provides Execute mode.
As shown in Fig. 1-Fig. 9, the split blade type wind turbine tower in this detailed description of the invention includes tower shell ring 1, Multiple tower shell rings 1 being sequentially overlapped form complete pylon.The upper end of tower shell ring 1 and a upper tower shell ring The lower end of 1 is welded with flange 3, is connected by flange 3 between tower shell ring 1.Tower shell ring 1 can phase by three pieces The tower shell ring sheet 2 being spliced into complete tower shell ring mutually forms, and tower shell ring 1 is divided into three pieces in the vertical in equal size Tower shell ring sheet 2.Deformation as this detailed description of the invention, it is obvious that tower shell ring 1 can also by two pieces or The tower shell ring sheet 2 of more than four pieces forms.Tower shell ring directly the biggest, can disassemble into more multi-disc by tower shell ring The tower shell ring sheet of number.
In this specific embodiment, the tower shell ring sheet 2 that two panels is adjacent connects in the following way: tower cylinder The both sides of nodal plate 2 have multiple connecting hole 9, vertically arrange.Connection member includes that interior connection sheet 5 is with outer Connecting sheet 4, interior connection sheet 5 and outer connection sheet 4 all have multiple first installing hole and multiple second installing hole, many The position of individual first installing hole and multiple second installing hole respectively with multiple connecting holes pair of adjacent tower shell ring sheet Should.Method of attachment be by the tower shell ring sheet 2 that interior connection sheet 5 and outer connection sheet 4 are adjacent clip together (as Shown in Fig. 5), then tighten together (as shown in Figure 6) with bolt 6, packing ring 7 and nut 8.Wherein, fastening Part can select high-strength bolt, snap bolt, stop nut etc., it is obvious that those skilled in the art are also Other suitable securing member can be selected according to actual needs.Between adjacent tower shell ring sheet 2, there is gap 10, packing material it is filled with.After all installing, outer connection sheet 4 surrounding coats packing material.As The deformation of this detailed description of the invention, it is also possible to connected outside by nut-welding on sheet 4, with screw rod interior connection sheet 5 Couple together with tower shell ring sheet 2 with outer connection sheet 4, interior connection sheet 5 is installed pad and nut (such as Fig. 8 Shown in).
In this specific embodiment, tower shell ring 1 cross section entirety can be circular.Be positioned at the first installing hole and Two bolts of the second installing hole can be parallel to each other (as shown in Figure 6), it is also possible to two bolts are both facing to circle The center of circle (as shown in Figure 7).No matter it is the parallel circle center of circle that is also directed towards of bolt, the most concrete as one Embodiment, the outer surface of interior connection sheet 5 is close to the inner surface of tower shell ring 1, and the inner surface of outer connection sheet 4 is tight The outer surface of patch tower shell ring 1.
Tower shell ring 1 cross section entirety can not also be circular.As it is shown in figure 9, tower shell ring 1 can phase by four pieces Being spliced into the tower shell ring sheet composition of complete tower shell ring mutually, the tower shell ring 1 after composition has and is positioned at four direction On planar section.
Preferred embodiment of the present utility model described in detail above.Should be appreciated that the ordinary skill of this area Personnel just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all Technical staff passes through logical analysis on the basis of existing technology, pushes away according to design of the present utility model in the art Reason or the limited available technical scheme of experiment, all should be at the protection domain being defined in the patent claims In.
