Abstract
The utility model discloses a flange at the bottom of a wind power tower barrel. The flange is characterized by comprising two concentric integrated connecting rings and a fixing ring, wherein the two connecting rings are positioned on the left side and the right side of the fixing ring; the thickness of the fixing ring is greater than that of each connecting ring on the same base plane; a plurality of through holes are uniformly distributed on the surfaces of the connecting rings; and the connecting rings and the fixing ring are inclined inwards on corresponding base planes. Compared with a common flange, the wind power flange has the advantages that: one more connecting ring and the through holes on the surfaces of the connecting rings are provided, so that tower barrels at the bottom of a tower frame of a wind generating set are stably connected.
Description
Technical field
The utility model relates to the flange field, is specifically related to the flange of a kind of wind-power tower bottom.
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 vibrations of the thrust of wind on impeller, moment of torsion, motor gear, control the preparation process of pylon well, and most important to the steadiness of wind-driven generator, service life etc.In the existing technology, the bottom column tube of wind-power generating unit tower is difficult to stablize.
The model utility content
The purpose of the utility model is the deficiency that overcomes existing technology, through flange arrangement is transformed, provides a kind of bottom column tube of wind-power generating unit tower that can make to stablize flange connecting.
To achieve these goals; The technological scheme of the utility model provides the flange of a kind of wind-power tower bottom, it is characterized in that, said flange comprises with one heart and two connecting rings of one, a retaining ring; Said two connecting rings are positioned at the left and right sides of retaining ring; Retaining ring thickness is greater than the thickness of connecting ring on same basal plane, several through holes that evenly distribute on the anchor ring of said connecting ring, and said connecting ring, retaining ring tilt on its basal plane to the inside.
The said through hole that is distributed on the inboard connecting ring is cylindrical, and the through hole on the connecting ring of the outside is a stepped shaft.
The beneficial effect of the utility model is: comparing general flange increases a connecting ring; More through hole distributes; The bottom column tube that makes wind-power generating unit tower is very firm after connecting through flange, just can bear the wind power generation stepped pylon that reaches tens meters and the effect of wind-force.
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 bottom is characterized in that, said flange comprises with one heart and two connecting rings of one 1, a retaining ring 2; Said two connecting rings 1 are positioned at the left and right sides of retaining ring 3; Retaining ring 3 thickness are greater than the thickness of connecting ring 1 on same basal plane, several through holes 2 that evenly distribute on the anchor ring of said connecting ring 1, and said connecting ring 1, retaining ring 3 tilt on its basal plane to the inside.
The said through hole 2 that is distributed on the inboard connecting ring 1 is cylindrical, and the through hole 2 on the outside connecting ring 1 is a stepped shaft.
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.
