Description
Technical field
The utility model relates to technical field of wind power generation, specially a kind of novel wind generator group tower doorframe.
Background technique
Wind energy is a kind of widely distributed, cleanliness without any pollution renewable energy, and has vast potential for future development.
Wind-power generating unit tower mostly uses greatly tower form, and bottom is provided with the door opening for personnel's disengaging, door opening
Opening weakens tower section, it is therefore desirable to which additional reinforcement measure, current way are directly to weld an annular slab doorframe
On door opening, this method has the advantage of simple structure, but there is also disadvantages: for guarantee door opening commissure fatigue strength and
The stability of tower column shell, it has to use thicker tower, cause the waste of material.
Utility model content
The purpose of this utility model is to provide a kind of novel wind generator group tower doorframes, and having can effectively improve
The stability of cylinder and its fatigue strength of weld seam near door opening, so that solving cannot be effective the advantages of reducing tower weight
Ground improves the door opening nearby stability of cylinder and its fatigue strength of weld seam, thus the problem of reducing tower weight.
To achieve the above object, the utility model provides the following technical solutions: a kind of novel wind generator group tower door
Frame, including upper tower body, lower tower body, transition body and reinforce ring body, it is provided with door opening on the upper tower body and lower tower body, institute
It states by solder design between tower body and lower tower body, the wall thickness of the transition body is greater than upper tower body and lower tower body
Wall thickness and be welded on door opening by weld seam, the reinforcement ring body is welded on transition body by weld seam.
Preferably, the transition body radius of curvature and upper tower body are identical as the radius of curvature of lower tower body.
Preferably, the upper tower body and lower tower body are cylindrical shape.
Compared with prior art, the beneficial effects of the utility model are as follows:
The utility model constructs one by upper tower body, lower tower body, transition body and the setting for reinforcing ring body jointly
Novel wind generator group tower doorframe, wherein being greater than the wall thickness of upper tower body and lower tower body by the wall thickness of transition body and leading to
It crosses weld seam to be welded on door opening, the door opening nearby stability of cylinder and its fatigue strength of weld seam can be effectively improved, thus
The weight of tower is reduced, the cooperation of the above structure solves the stability and its weldering that cannot effectively improve cylinder near door opening
The fatigue strength of seam, thus the problem of reducing tower weight.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model schematic cross-sectional view；
Fig. 3 is the utility model doorframe partial enlargement schematic cross-sectional view.
In figure: ring body is reinforced in tower body, 2 lower tower bodies, 3 transition bodies, 4 on 1.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1-3, a kind of novel wind generator group tower doorframe, including upper tower body 1, lower tower body 2, transition
Body 3 and reinforce ring body 4, door opening is provided on upper tower body 1 and lower tower body 2, upper tower body 1 and lower tower body 2 are cylinder
Shape, by solder design between upper tower body 1 and lower tower body 2, the wall thickness of transition body 3 is greater than upper tower body 1 and lower tower
It the wall thickness of body 2 and is welded on door opening by weld seam, the curvature half of 3 radius of curvature of transition body and upper tower body 1 and lower tower body 2
Diameter is identical, can increase the stability of tower, improves service efficiency, reinforcement ring body 4 be welded on transition body 3 by weld seam,
By upper tower body 1, lower tower body 2, transition body 3 and the setting for reinforcing ring body 4, a novel wind generator is constructed jointly
Group tower doorframe, wherein being greater than the wall thickness of upper tower body 1 and lower tower body 2 by the wall thickness of transition body 3 and being welded by weld seam
On door opening, the door opening nearby stability of cylinder and its fatigue strength of weld seam can be effectively improved, to reduce tower
Weight, the cooperation of the above structure, the fatigue for solving the stability and its weld seam that cannot effectively improve the neighbouring cylinder of door opening are strong
Degree, thus the problem of reducing tower weight.
In use, constructing one jointly by upper tower body 1, lower tower body 2, transition body 3 and the setting for reinforcing ring body 4
A novel wind generator group tower doorframe, wherein being greater than the wall of upper tower body 1 and lower tower body 2 by the wall thickness of transition body 3
Thick and be welded on door opening by weld seam, capable of effectively improving door opening, nearby the stability of cylinder and its fatigue of weld seam is by force
Degree, so that the weight of tower is reduced, and 3 radius of curvature of transition body and upper tower body 1 are identical as the radius of curvature of lower tower body 2,
The stability of tower can be increased, improve service efficiency, the cooperation of the above structure, solving cannot effectively improve near door opening
The stability of cylinder and its fatigue strength of weld seam, thus the problem of reducing tower weight.
In summary: the novel wind generator group tower doorframe passes through upper tower body 1, lower tower body 2,3 and of transition body
The cooperation for reinforcing ring body 4, the door opening nearby stability of cylinder and its fatigue strength of weld seam cannot be effectively improved by solving, from
And the problem of reducing tower weight.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
