Embodiment Construction
[0012] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0013] Such as figure 1 with figure 2 As shown, a wind power generator tower base ring includes an annular body 1, the upper end of the annular body 1 is provided with an upper connection part 2 connected to the lower end of the generator tower, the upper connection part 2 is a flange, and the lower end of the annular body 1 is provided with Some lower bottom plates 3, the lower bottom plates 3 can be embedded in the foundation horizontally, so that the lower bottom plates 3 can ensure the verticality of the annular body 1, so that the generator tower is not inclined. The outer wall of the annular body 1 is provided with a plurality of radial outer reinforcing plates 4 in the circumferential direction, the radial outer reinforcing plates 4 are "T" shaped plates, and the radial outer reinforcing plates 4 are provided with holes 41 for piercing ...

The invention relates to a foundation ring of a wind driven generator tower barrel. The foundation ring comprises a ring body, wherein an upper end of the ring body is provided with an upper connection portion connected with a lower end of the generator tower barrel, and a lower end of the ring body is provided with a lower bottom plate; the technical points in the invention are as follows: a plurality of radial outer reinforcement plates are circumferentially arranged on an outer wall of the ring body; and the radial outer reinforcement plates are provided with holes through which reinforcing steel bars penetrate. The radial outer reinforcement plates are arranged to increase contact area between the foundation ring and concretes, and enhance firmness, so that the tower barrel is mounted more firmly.
Description
【Technical field】 [0001] The invention relates to a foundation ring of a wind power generator tower, in particular to a foundation ring for fixing a wind power generator tower. 【Background technique】 [0002] At present, megawatt-level wind turbines are supported high in the air by towering towers, and the foundation ring under the towers bears huge vertical pressure and lateral bending moment. The upper end of the traditional foundation ring is connected to the bottom of the generator tower through a flange, and the upper part of the foundation ring is radially opened to allow steel bars to pass through it, and then embedded in the concrete foundation, because the openings in the upper part of the foundation ring reduce the connection strength , and will produce stress concentration phenomenon at the opening, and accelerate structural fatigue. 【Content of invention】 [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide...
