Embodiment 1

[0022] Such as figure 1 with figure 2 As shown, a foundation of a wind power generation unit in the intertidal zone includes a main cylinder 1, an upwardly inclined support rod 2, a downwardly inclined support rod 3, and five steel pipe piles 4 evenly distributed along the circumference, and each steel pipe pile is covered with There are pile casings 5, the main cylinder body 1 includes a connecting section 6, an intermediate section 7 and a fixed section 8, and each pile casing 5 is connected to the connecting section 6 of the main cylinder body 1 through an upwardly inclined support rod 2, each The root pile casing 5 and the fixed section 8 of the main cylinder 1 are connected by a downwardly inclined support rod 3, the middle section 7 of the main cylinder 1 has an inverted conical structure, and the connecting section 6 and the fixed section 8 are both cylindrical structure; such as Figure 4-7 As shown, in order to further improve the stability of the base, a horizonta...

Embodiment 2

[0026] Except that there are six steel pipe piles 4, other structures and the relationship between the structures are the same as in Embodiment 1.

Abstract

The invention discloses an intertidal zone wind generating set base which comprises a main cylindrical body, an upper diagonal support rod, a lower diagonal support rod and multiple steel pipe piles uniformly distributed along the circumference, wherein pile sleeves are sleeved on the steel pipe piles; the main cylindrical body comprises a linkage section, an intermediate section and a fixed section, wherein the intermediate section of the main cylindrical body is of an inverted cone frustum structure; the linkage section and the fixed section are of a cylindrical structure; the fixed section is internally provided with a transverse reinforcing ring I and a vertical reinforcing plate I; the upper part and lower part of the interior of the linkage section are provided with transverse reinforcing rings II; vertical reinforcing plates II are arranged between the two transverse reinforcing rings II. The bearing capability of the base is improved; the reinforcing rings and the reinforcing plates are additionally arranged in the fixed section and the linkage section, so that the stability between the main cylindrical body and the upper diagonal support rod and the stability between the main cylindrical body and the lower diagonal support rod are enhanced, and further the stability of the base is improved. Compared with a traditional base, the base disclosed by the invention has the advantage that one central steel pipe pile is omitted, so that the construction difficulty and the production cost are reduced to a greater degree.

Description

technical field [0001] The invention relates to a foundation of a wind power generator set, in particular to a foundation of a wind power generator set in an intertidal zone, and belongs to the field of offshore wind power generation equipment. Background technique [0002] The development and utilization of wind energy has a long history. In recent years, offshore wind power generation, as a renewable clean energy, has been highly valued by governments, energy circles and environmental protection circles around the world. However, building a wind turbine at sea requires a solid base, and the current offshore wind turbine base can withstand a small load, and its material and construction costs are high, and construction is difficult. Therefore, a new technical solution is needed to solve the above technical problems. Contents of the invention [0003] The object of the present invention is to provide a foundation for a wind power generating set in an intertidal zone, wh...
