Foundation of wind generating set

Abstract

The invention relates to a foundation of a wind generating set, in particular to a foundation of a high-power wind generating set more suitable for regions with poor geological conditions such as beaches or shallow seas and more capable of preventing the wind generating set from toppling. The foundation is structurally characterized in that: at least three cantilever beams bearing main toppling flexural moment of the wind generating set are distributed in radial shape around a bearing platform bearing main vertical load of the wind generating set; cantilever beam pillow blocks are positioned below the cantilever beams and arranged between the outer ends of the cantilever beams and the bearing platform; the upper end of an anchor rod or an anchor rope is connected with the outer end of the cantilever beam, and the lower end of the anchor rod or the anchor rope is connected on an anchor body embedded into the ground or thrown into the water; and the foundation supported below the bearing platform and the cantilever beam blocks is an integral connected foundation or a split foundation corresponding to the positions of the bearing platform and the cantilever beam blocks. The parts, except the bearing platform, of the foundation can be produced in a factory, so the field construction is convenient, and the building cost is lowered.

Description

technical field [0001] The invention relates to a foundation of a wind power generating set, in particular to a foundation of a high-power wind generating set which is more suitable for areas with poor geological conditions such as tidal flats or shallow seas and can better prevent the wind power generating set from overturning. Background technique [0002] The mechanical characteristic of the foundation of the wind turbine is that it must bear the vertical load Fz, the overturning moment Mr, the horizontal load Fr and the torque Mz of the unit at the same time, and the horizontal load Fr and the overturning moment Mr may come from any direction, where The overturning moment Mr is the main control condition of foundation stability. At present, there are mainly the following types of foundations for onshore wind turbines: [0003] 1. Solid gravity foundation. This kind of foundation is completely stable by its own weight or the soil and rocks loaded on the foundation. The a...

Problems solved by technology

This extended foundation is a combination of prefabricated components and cast-in-place, which is conducive to speeding up the construction of the foundation, ensuring quality and reducing construction costs. However, the final structure of the wind turbine foundation disclosed in this patent document is similar to that of patent document 1. , the same problem is: it is easy to overturn in places with poor geological conditions, and the bottom plate is poured on site. If it is made to a large size, its manufacturing cost, transportation cost, and installation cost are quite huge
