  • the wind turbine tower 100 is shown generally in FIG. 1.
  • the wind turbine tower 100 consists of a tower 102 and a turbine generator 104.
  • a turbine generator 104 is any electric generator that can convert the kinetic energy of the wind movement into electrical energy. Any generator may be used. Stronger winds that have higher velocities may allow for the use of the more powerful generators. Thus, strong, upper elevation winds, may allow the use of 5MW or even more powerful generators. However, one skilled in the art will recognize that the type or power rating of the generator 104 is immaterial to the invention. Generally, the generator 104 is attached to a set of blades 106a, 106b, and 106c or instruments that capture the wind energy and use it to m the electric generator 104. Several designs of blades are possible. The present invention has three propeller-type blades 106a, 106b, and 106c.
  • the blades 106a, 106b, and 106c can be specially shaped to convert the inflow energy of the wind (linear movement of the wind) into rotational energy of the blades (movement in the blades) 106a, 106b, and 106c and the generator 104.
  • the present invention focuses on the tower 102.
  • the tower 102 is a composite structure. Several embodiments of the structure may exist.
  • the tower 102 may be made from one or more tower sections 108a, 108b, and 108c, sometimes referred to herein more generally as 108 where it does not indicate any one section in particular. In the embodiment shown in FIG.
  • the tower 102 has three tower sections 108a, 108b, and 108c. While the embodiment shown includes three tower sections 108a, 108b, and 108c, one skilled in the art will recognize, after reviewing this description, the tower 102 can be made from one or more tower sections.
  • the tower 102 also demonstrates that the tower sections 108a, 108b, and 108c may be nested, and the tower 102 may be telescoped into a fully extended height. Again, this embodiment is only exemplary, and the tower 102 may not be nested or telescoped but can be arranged as one or two or more sections of equal diameter that are connected together.
  • the tower 102 may require a telescoped and nested configuration for ease of erection and installation.
  • the embodiment shown includes sections 108a, 108b, and 108c that are hexagonal in cross section. This shape is exemplary.
  • Each section 108a, 108b, or 108c may adopt one of numerous choices for cross sections. These cross sections may include, but are not limited to, any polygon, a circle, or an ellipse (oval).
  • each section 108a, 108b, and 108c of the tower 102 may have a unique and different cross section from the other sections or may have a similar or the same cross section as the other sections.
  • a tower 102 may employ and be anchored by one or more sets of guy wires.
  • the embodiment shown has two sets of guy wires 110 and 112.
  • Each set of guy wires 110 and 112 may have a plurality of wires that brace the tower 100.
  • the embodiment shown includes three guy wires in each set. While it may be possible to use fewer than three wires, it is preferred that each set of guy wires 110 or 112 include three or more wires to brace the tower against deflection in any direction.
  • the guy wires may be made of any material strong enough and rigid enough to brace the tower 100.
  • the guy wires 110 or 112 are a steel cable.
  • the guy wires 110 or 112 may be attached to one or more connectors (shown later) on the tower 102. An exemplary embodiment of a connector will be described below. Also, the guy wires 110 or 112 should be connected to an anchor point (not shown) set on or in the ground.
  • the anchor can be a concrete post or footing with a clevis or eye to connect the wire.
  • Two or more guy wires may share a connection to the tower 102 or an anchor point. Each guy wire can have a certain angular relationship to the tower 102 and the ground. These relationships must provide the adequate bracing for the tower 100 from deflection in the tower 102.
  • One skilled in the art will be capable of determining the appropriate angle for the guy wires 110 or 112 in accordance with the present invention.
  • guy wires 110 or 112 are not required for the support of a tower 100. Indeed, as the towers get increasingly larger, the influence of guy wires diminishes due to the large moments of inertia of the different telescoping sections, which make up the tower. This embodiment would be attractive for the emerging offshore tower installations because creating the attachment points for connecting the guy wires in an offshore environment is very difficult to do and also expensive and time consuming. Referring to FIG. 1

In other embodiments, the door 1424 may provide access to the bottom of the hole 1402, where the personnel may scale the tower 102 from that point.
