Abstract
The utility model discloses a flange on the top of a wind power generation tower barrel. The flange is characterized by comprising a connecting ring, a positioning ring and a fixing ring which are concentric and integrated with one another, wherein the positioning ring is positioned on the inner side of the connecting ring, and is used for positioning the wind power generation tower barrel; the fixing ring is positioned on the outer side of the connecting ring, and is staggered with the connecting ring; and a plurality of through holes are uniformly formed on the ring surface of the connecting ring. The wind power generation flange is conveniently welded with a frame of the wind power generation tower barrel, can stably support the frame of a generator set, and is widely applied to strong wind environments in which large wind power generator sets are placed.
Description
Technical field
The utility model relates to the flange field, is specifically related to the flange at a kind of wind-power tower top.
Background technique
Flange is crucial link, the supporting element in the wind power plant, along with the rapid growth of wind-power electricity generation, and the maximization that becomes gradually of the equipment of wind-power electricity generation, therefore also strict more to the requirement of flange product each item technical performance.Wind power flange at present commonly used does not have retaining ring mostly, during with the pylon welding of wind power generating set, and inconvenient operation, the welding back is unstable, can not satisfy the requirement of Large-scale Wind Turbines stable operation under strong wind atmosphere.
The model utility content
The purpose of the utility model is the deficiency that overcomes existing technology, through flange arrangement is transformed, the top flange of the wind-power tower that a kind of tower tube that can make wind power generating set is fixedly connected is provided.
To achieve these goals, the technological scheme of the utility model provides the flange at a kind of wind-power tower top, it is characterized in that; Said flange comprises with one heart and connecting ring, positioning ring and the retaining ring of one that said positioning ring is positioned at the inboard of said connecting ring, and two end faces of positioning ring are positioned between two end faces of connecting ring; The location that is used for wind power tower drum; Said retaining ring is positioned at the outside of connecting ring, and with the connecting ring dislocation, several through holes evenly distribute on the anchor ring of said connecting ring.
Said through hole circularizes arrangement.
Said through hole divides two rows to be interspersed on the anchor ring of connecting ring.
The beneficial effect of the utility model is: the connecting ring of this flange is connected with the retaining ring dislocation; Simple to operate when making the welding of wind power flange and wind power generation stepped pylon; And can stablize the pylon of wind power generating set, satisfy the requirement of wind-driven generator stable operation under the strong wind condition.
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 at a kind of wind-power tower top is characterized in that; Said flange comprises with one heart and connecting ring 1, positioning ring 2 and the retaining ring 3 of one; Said positioning ring 2 is positioned at the inboard of said connecting ring 1, and two end faces of positioning ring 2 are positioned at the location that is used for wind power tower drum between two end faces of connecting ring 1, and said retaining ring 3 is positioned at the outside of connecting ring 1; With connecting ring 1 dislocation, several through holes 4 evenly distribute on the anchor ring of said connecting ring 1.
Said through hole 4 circularizes arrangement.
Said through hole 4 minutes two rows be interspersed on the anchor ring of connecting ring 1.
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.
