Wind power generation is one of the most mature power generation modes with the largest development scale and commercial prospect in new energy power generation technology. Due to the prominent effects of the composite material in optimizing energy structures, improving ecological environment and promoting sustainable development of social economy. The wind turbine tower base serves as an important component of a wind power generation structure, all loads borne by an upper wind turbine tower structure are transmitted to a foundation, and the overall stability of the structure is maintained.
Therefore, it is necessary to design a wind power bearing platform which can meet the requirements of post-tensioning and anchoring of prestressed steel strands and ensure that the bearing platform has sufficient overall strength and rigidity.
Disclosure of Invention
The utility model discloses broken through prior art's a difficult problem, designed a cavity formula wind-powered electricity generation cushion cap in floorbar strenghthened type, made its back stretch-draw and the anchor demand that can satisfy the prestressing force steel strand wires that a prestressed concrete tower section of thick bamboo needs, possessed sufficient bulk strength and rigidity again simultaneously.
In order to achieve the purpose, the utility model discloses a cavity formula wind-powered electricity generation cushion cap in floorbar strenghthened type, its characterized in that: the cushion cap center is equipped with the cavity, the back stretch-draw, the anchor of the prestress wire of being convenient for and maintain the change, and the cushion cap below is provided with a plurality of floorbeams, the overall arrangement mode of floorbeam is for laying out about cushion cap central rotational symmetry.
Furthermore, a circle of anchoring surface is arranged on the outer edge of the lower part of the cavity.
Furthermore, a sleeve is arranged in the bearing platform above the anchoring surface.
Further, the prestressed steel strand is fixed with the anchoring surface through the sleeve.
Furthermore, the radius of the cavity is 3-4 m.
Further, the number of the bottom beams is determined by the size of the bearing platform and the area of the cavity.
Compared with the prior art, the utility model, designed a novel cushion cap basis suitable for back stretch-draw prestressed concrete tower section of thick bamboo, possessed the back stretch-draw and anchor demand, cushion cap bulk strength, the high advantage of rigidity that satisfy prestressed steel strand wires, designed the cavity that can guarantee personnel's operation simultaneously under the prerequisite that reduces the structure weakening of cushion cap.

In the specific embodiment, a bottom beam reinforced hollow wind power bearing platform is designed, a cavity 2 is formed in the center of a conventional circular bearing platform 1, the radius of the cavity 2 is 3-4 m, post tensioning, anchoring, maintenance and replacement of prestressed steel strands are facilitated, the operation space of personnel is guaranteed, and meanwhile weakening of the structure of the bearing platform is reduced as far as possible. The bottom of the bearing platform 1 is provided with a plurality of bottom beams 3 along the radius direction, and the layout mode of the bottom beams 3 is rotationally and symmetrically arranged around the center of the bearing platform 1 so as to improve the strength and the rigidity of the bearing platform and reduce the weakening of the hollow bearing platform on the structural performance of the bearing platform.
Preferably, the number of bottom beams 3 is determined by the size of the platform 1 and the area of the cavity 2.
Meanwhile, a sleeve of the prestressed steel strand is reserved in the bearing platform, a circle of prestressed steel strand anchoring surface is arranged at the lower edge of the cavity position and serves as an anchorage installation position, and the prestressed steel strand is fixed with the anchoring surface 4 through the sleeve 5.
In the construction, the arrangement number and the layout mode of prestressed steel strand sleeves 5 in a bearing platform 1 are determined according to the diameter of an upper wind power tower cylinder and the number of required prestressed steel strands, the area of a cavity 2 is determined by comprehensively considering the operation space of personnel, an anchoring surface 4 meeting the requirement of an anchorage device is formed, and the lower part of the bearing platform 1 is reinforced by a bottom beam 3 so as to reduce the weakening of the structural performance of the hollow bearing platform.
When the wind power tower cylinder is installed, the prestressed steel strands penetrate through the reserved sleeve 5, anchoring is carried out on the anchoring surface 4, and when a certain prestressed steel strand fails, replacement can be carried out through the cavity 2 in the bearing platform 1.
