Problems solved by technology

Although the material requirements for the foundation of a wind turbine space frame tower are significantly lower than for a conventional single-tube tower, the total amount of concrete, steel bars and other reinforcements is still costly
In addition, due to the space frame tower design of conventional wind turbines, additional structures must be constructed on site to house any required down tower equipment or components, as exist in conventional wind turbine space frame towers. Insufficient storage space in the tower

Embodiment Construction

[0025] Such as figure 1 As shown in , wind turbine 16 generally includes a nacelle 20 that houses a generator (not shown). The nacelle 20 is mounted atop a tower transition piece 32 using flanges (not shown) on top of the space frame type tower 30 . The height of tower 30 is selected based on factors and conditions known in the art, and may extend to a height of 60 meters or more. Wind turbine 16 may be installed on any terrain that provides access to an area with desired wind conditions. Terrain can vary widely, and can include, but is not limited to, mountainous terrain or offshore locations. Wind turbine 16 also includes a rotor 22 that includes one or more rotor blades 24 attached to a rotating hub. although figure 1 The wind turbine 16 shown in FIG. 1 includes three rotor blades 24, but there is no particular limitation on the number of rotor blades 24 required by the present invention. The space frame tower 30 includes a plurality of vertical tower support members 3...

Abstract

The present disclosure is directed to a modular surface foundation for wind turbine space frame towers, specifically a modular surface foundation for wind turbine space frame tower (30), an apparatus to form panels of housing members (44) of modular surface foundation, and method of forming the modular surface foundation for wind turbine space frame towers (30) is provided. The modular surface foundation comprises a plurality of footing members, and a housing member disposed on each of the footing members, the housing members (44) extending from the footing members and attaching to one or more structural members forming a portion of a wind turbine tower, wherein the housing member (44) provides support and increased height for the space frame tower (30) and includes an interior space.

Description

technical field [0001] The present disclosure is directed to a modular surface foundation for a wind turbine space frame type tower, an apparatus to form a plurality of panels of shell components of the modular surface foundation, and forming a space for a wind turbine Method for modular surface foundations of framed towers. Background technique [0002] In recent years, wind turbines have received increasing attention as an environmentally safe and relatively inexpensive alternative energy source. With this growing interest, considerable efforts have been made to develop wind turbines that are reliable, efficient and cost-effective to install. [0003] Typically, a wind turbine includes a rotor with a plurality of blades. The rotor is mounted via a hub, main shaft and bearings to a casing or nacelle which sits on top of a lattice or tubular tower. Utility grade wind turbines (ie, wind turbines designed to provide electrical power to a utility grid) may have large rotors ...
