It is high.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of wind turbine tube structure, including inner cylinder, outer barrel and stent preform, it is characterised in that：It is set on the inner tank theca
Have an inner sleeve plate, outer tube inner wall is equipped with flag, inner sleeve plate and flag towards inlet side one end respectively with corresponding inner cylinder
It is tightly connected with outer barrel, inner sleeve plate and the flag other end are opening, and the stent preform includes in corresponding with inner sleeve plate
Positioning plate and outer positioning plate corresponding with flag, interior positioning plate and outer positioning plate are annular plate, interior positioning plate and outer positioning
It is connected and fixed by radially-arranged at least three supporting rod between plate, interior positioning plate and outer positioning plate side are inserted into pair respectively
It is in the opening of the inner sleeve plate and flag answered and fixed.
It is equipped with the end plate for connecting the supporting rod on rear side of the interior positioning plate and outer positioning plate, is preset on end plate
Jack, support boom end are inserted into jack and fixed.
The supporting rod section is V-type framework, and its tip is arranged towards inlet side.
The utility model has the beneficial effects that：It is reasonable in design, interior positioning plate, outer positioning plate and the support of stent preform
Stent preform is inserted into inner sleeve plate when assembly by the advance welding fabrication of bar, while prefabricated inner sleeve plate and flag in cylinder respectively
It being fixed with flag so that the position of supporting rod can accurately be processed, and the accurate welding in small space is avoided to operate,
The connection structure intensity between component is increased simultaneously.

Specific implementation mode
Illustrate that the embodiment of the utility model, those skilled in the art can be by these by particular specific embodiment below
Content disclosed by specification understands other advantages and effect of the utility model easily.
As shown in Figure 1,2,3, 4：A kind of wind turbine tube structure, including inner cylinder 2, outer barrel 1 and stent preform 3, wherein：
2 outer wall of the inner cylinder is equipped with inner sleeve plate 4, and 1 inner wall of outer barrel is equipped with flag 5, inner sleeve plate 4 and flag 5
In on the same axial position of cylinder, inner sleeve plate 4 and flag 5 towards inlet side one end distinguish bending and with corresponding inner cylinder
2 and outer barrel 1 weld, achieve the effect that sealed connection, inner sleeve plate 4 and 5 other end of flag are opening, inner sleeve plate 4 and flag 5
The position limiting structure for being provided as installation stent preform 3, the opening for passing through inner sleeve plate 4 and flag 5 realizes the dress of stent preform 3
Match；
The stent preform 3 includes and the corresponding interior positioning plate 6 of inner sleeve plate 4 and outer positioning plate corresponding with flag 5
7, it is connected and fixed by radially-arranged three supporting rods 8 between interior positioning plate 6 and outer positioning plate 7, interior positioning plate 6 and outer positioning
Plate 7 is the annular plate for being parallel to cylinder lateral wall, and the thickness of interior positioning plate 6 and outer positioning plate 7 is opened with inner sleeve plate 4 and flag 5
Matched at mouthful makes the side of interior positioning plate 6 and outer positioning plate 7 be inserted into corresponding inner sleeve plate 4 and flag 5 respectively
In opening and it is welded and fixed.
The interior positioning plate 6 and the rear side of outer positioning plate 7 are equipped with the end plate 9 for connecting the supporting rod 8, on end plate 9
It is preset with jack, 8 end of supporting rod is inserted into jack and is welded and fixed, and fixed supporting rod 8 is being realized in the setting by end plate 9
On the basis of, the weight of stent preform 3 is alleviated, while plate is welded and fixed with end plate 9 on the basis of grafting again, connection knot
Structure intensity is high.
8 section of the supporting rod is V-type framework, and its tip is arranged towards inlet side, on the basis for ensureing support strength
On, reduce windage.
In said structure, stent preform 3 can independent machine-shaping, while prefabricated inner sleeve plate 4 and housing in cylinder
Stent preform 3 is assembled in cylinder and is connected and fixed with inner sleeve plate 4 and flag 5 by plate 5, which can substitute existing
The mounting means and structure of supporting rod 8 in technology, overall construction intensity higher, the stability that stent preform 3 is constituted are more preferable, can
Effectively to support and fix inner cylinder 2 and outer barrel 1, simultaneously support 8 end of bar by corresponding interior positioning plate 6 and outer positioning plate 7 into
Luggage is matched, and for being welded and fixed with 8 end of existing supporting rod, 8 end of supporting rod after improving is more firm, whole to improve
The product quality of wind turbine.
The foregoing is merely the preferred embodiments of the utility model, as long as realizing the utility model with essentially identical means
Purpose technical solution, belong within the scope of protection of the utility model.
