Description

Cement foundation of wind generating set

Technical Field

The utility model relates to a cement foundation of a wind generating set.

Background

The cement foundation of the existing wind generating set adopts: after the reinforced concrete is poured once, a secondary cement mortar plastering process is adopted, and the process has the defects that the construction is complicated and needs to be completed twice, and the primary defect that the secondary cement mortar plastering is not easy to combine with the poured reinforced concrete and is extremely easy to fall off in practical application.

Disclosure of Invention

The utility model aims to provide a cement foundation of a wind turbine generator system, which aims to solve the problems that the cement foundation of a wind turbine generator in the prior art is easy to fall off after pouring and is complex in construction.

In order to solve the problems, the cement foundation of the wind generating set adopts the following technical scheme:

the cement foundation of the wind generating set comprises a cement foundation reinforcement cage and concrete poured in the reinforcement cage, wherein the reinforcement cage comprises a base section, an inclined strut section and a foundation ring section which are arranged from bottom to top; the size of base section is greater than the size of basic ring section, the outside of base section encloses and is equipped with round guard plate, the top of guard plate is higher than the top of base section, the bottom of guard plate is pre-buried in underground, the inside wall of guard plate with the bracing piece fixed connection of base section.

Further, the guard plate is formed by bending and surrounding a whole steel plate, and two ends of the steel plate are welded and fixed with each other after surrounding.

Further, the guard plate is formed by surrounding a plurality of steel plates arranged on the outer side of the base section side by side in sequence, and the head end and the tail end of two adjacent steel plates are welded and fixed.

Further, the inner side of the protection plate is welded and fixed with the supporting beam.

Further, the outside of the protection plate is smeared with anti-corrosion paint.

The beneficial effects of the utility model are as follows: compared with the prior art, the cement foundation of the wind generating set has the advantages that a layer of closed protection plate edge is humidified on the outer surface of concrete, the protection plate is fixedly connected with the reinforcement cage before concrete pouring, and the external protection plate and the reinforced concrete are perfectly combined together to form a whole during concrete pouring, so that secondary cement mortar plastering is not needed for protection. In addition, the bottom of guard plate is pre-buried in underground, prevents that the guard plate from receiving weather environment or external factor to lead to breaking away from with the concrete, under the restriction of steel reinforcement cage and underground soil, guarantees the stability of its structure.

Detailed Description

In order to make the technical purpose, technical scheme and beneficial effect of the present utility model more clear, the technical scheme of the present utility model is further described below with reference to the accompanying drawings and specific embodiments.

The concrete embodiment of the cement foundation of the wind generating set, as shown in fig. 1 to 3, comprises a cement foundation reinforcement cage 1 and concrete 2 poured in the reinforcement cage 1, wherein the reinforcement cage 1 comprises a base section 3, a diagonal bracing section 4 and a foundation ring section 5 which are arranged from bottom to top; the structure and the assembly form of the sections of the reinforcement cage 1 are identical to those of the prior art, and the size of the base section 3 is greater than that of the base ring section 5, not described in detail.

In this embodiment, the outside of base section 3 encloses and is equipped with round guard plate 7, and the top of guard plate 7 is higher than the top of base section 3, and the bottom of guard plate 7 is pre-buried in underground, the inside wall of guard plate 7 with the bracing piece 6 fixed connection of base section 3. Specifically, the protection plate 7 is formed by a plurality of steel plates which are arranged on the outer side of the base section 3 in a side-by-side and sequential manner, and the head ends and the tail ends of two adjacent steel plates are welded and fixed. The adoption of the steel plate mainly considers the factors such as the protection cost, the structural stability and the like, and is convenient to fixedly connect with the reinforcement cage 1. Meanwhile, the steel plate is not easy to deform, and the surface is smooth and clean.

In this embodiment, because the material of steel reinforcement cage 1 and guard plate 7 is steel, for convenient the connection, guarantee the overall structure's after-connection stability simultaneously, guard plate 7's inboard and bracing beam 6 welded fastening. Because the outer side wall of the base section 3 is surrounded by a plurality of supporting beams 6 which extend up and down, the inner side wall of the protection plate 7 and each supporting beam 6 are welded and fixed in sequence directly in the process of surrounding the protection plate 7 on the outer side wall of the base section 3, the structural stability is ensured, and meanwhile, the protection plate 7 can also form an outer template of the reinforcement cage 1.

After the integral pouring is finished, the outside of the protection plate 7 is coated with the anti-corrosion paint 8, and the final procedure is finished, so that the protection plate 7 has certain anti-corrosion performance.

Of course, in other embodiments, the protection plate 7 may be made of other alloy materials.

In other embodiments, the protection plate 7 is formed by bending and encircling a whole steel plate, and two ends of the steel plate are welded and fixed with each other after encircling.

In other embodiments, the protection plate 7 and the bracing beam 6 may be detachably connected by a weld nut.

Finally, what should be said is: the above embodiments are only for illustrating the technical solution of the present utility model, and any equivalent replacement of the present utility model and modification or partial replacement without departing from the spirit and scope of the present utility model should be covered in the scope of the claims of the present utility model.
