Abstract
The utility model discloses a flange for a transitional section of a wind power generation tower barrel. The flange is characterized by comprising a connecting ring and a fixing ring which are concentric and integrated, wherein the fixing ring is positioned on the outer side of the connecting ring; the fixing ring is thicker than the connecting ring on the same base face; a plurality of through holes are uniformly formed in the ring face of the connecting ring, and used for connecting two wind power generation tower barrels; and the connecting ring and the fixing ring are inclined towards the inner side on the same base face. When the wind power generation flange is welded with the wind power generation tower barrel, the planeness of two flanges is adjusted, so that the flange cannot be loosened when welded with a rolling barrel body; and the deformation of the welded flange is small.
Description
Technical field
The utility model relates to the flange field, is specifically related to a kind of flange of wind-power tower changeover portion.
Background technique
The wind-power electricity generation pylon is critical support parts of wind-driven generator, and it relies on adpting flange to form a tapered cylinder shape structure by several sections conic tubes, and every section pylon is to be welded by rolling cylindrical shell and adpting flange.The main active force that pylon bore has: the swing of vibrations, gyrostatic moment and the stressed variation of the thrust of wind on impeller, moment of torsion, motor gear; Control the preparation process of pylon well, most important to the stability of wind-driven generator, service life etc.In the existing technology, easy deformation after becoming flexible easily, weld when rolling cylindrical shell and adpting flange welding.
The model utility content
The purpose of the utility model is the deficiency that overcomes existing technology, through flange arrangement is transformed, is difficult for loosening when the welding of a kind of and wind-power electricity generation rolling cylindrical shell is provided and the little adpting flange of welding back distortion.
To achieve these goals, the technological scheme of the utility model provides a kind of flange of wind-power tower changeover portion, it is characterized in that; Said flange comprises with one heart and connecting ring, the retaining ring of one; Said retaining ring is positioned at the outside of connecting ring, and fixed thickness is greater than the thickness of connecting ring on same basal plane, and several through holes evenly distribute on the anchor ring of said connecting ring; Be used to connect two wind-power towers, said connecting ring, retaining ring tilt on same basal plane to the inside.
The said through hole that is distributed on the connecting ring anchor ring circularizes arrangement.
The beneficial effect of the utility model is: the connecting ring of flange, the bottom surface of retaining ring tilt to the inside, and the planeness that can regulate two flanges when making the welding of wind power flange and wind power generation stepped pylon is not loosening when guaranteeing the welding of flange and rolling cylindrical shell.Retaining ring thickness reduces the angular distortion after flange and cylindrical shell weld greater than the thickness of connecting ring on same basal plane in addition, is convenient to the stable wind-powered electricity generation Tata tube that connects.
Description of drawings
Fig. 1 is the plan view of the top flange of wind power flange;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technological scheme of the utility model, and can not limit the protection domain of the utility model with this.
The technological scheme of the utility model practical implementation is:
Like Fig. 1, shown in Figure 2, the flange of wind-power tower changeover portion is characterized in that; Said flange comprises with one heart and connecting ring 1, the retaining ring 3 of one; Said retaining ring 3 is positioned at the outside of connecting ring 1, and retaining ring 3 thickness are greater than the thickness of connecting ring 1 on same basal plane, and several through holes 2 evenly distribute on the anchor ring of said connecting ring 1; Be used to connect two wind-power towers, said connecting ring 1, retaining ring 3 tilt on same basal plane to the inside.
The said through hole 2 that is distributed on connecting ring 1 anchor ring circularizes arrangement.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
Claims (2)
