The invention addresses the technical aspects of electricity generating plants, specifically wind power plants.
One of the purposes of the invention described here is to propose a new architecture that reduces mechanical stress as much as possible by unifying all the torque and tip-over moments into a single bending moment along the vertical axis, and a torque moment normal to the vertical axis of the tower. This improves the plant’s durability and useful life.
This new architecture simplifies the structure of the plant as far as possible by reducing the number of components that produce torque or tip-over moments, or eliminating them altogether.
This also makes maintenance easier and more economical, enabling the plant to be put back into service more quickly.
Moreover in this new architecture the mechanical parts are simpler to manufacture, which reduces their cost of manufacture.
This invention also incorporates an innovative wind capture system:
The wind is frontally intercepted by vertical blades (9), but unlike current vertical blade technology, in this case the active wind is captured along a rectilinear path only, and this gives better performance.
This is a new concept of power plant that is always in feathered mode and is always turned to capture the frontally impacting fluid vein.
Fig. 1 (right) shows that it has a low frontal impact as compared to current types of wind power plant.
This invention maximizes the wind capture area in the vertical axis only.
This reduces not only its visual impact but also the vortices generated by the structure, enabling the distance between adjacent plants to be reduced.
Since it occupies a smaller ground area, the costs of purchasing land are reduced.
The profile of the “orientable wing” superstructure (1) enables this plant to constantly adapt to the wind direction.
Its profile presents a low shape resistance, and this reduces the stresses induced by the wind, extending the operational life of the plant as a whole and of its individual components.
This new architecture resolves a hitherto intractable problem of the stresses produced by all the apparatus supported at the top of the tower of medium and high output horizontal-axis wind power plants.
All these illustrate components are supported for their full length by the body of the orientable wing (1). They perform the same function as the rotating blades of a conventional horizontal-axis rotor.
The components illustrated above are in standard production. Since many of them are identical, they can be mass produced more economically, in smaller factories.
The induced aerodynamic stresses are low, and unlike current horizontal-axis wind power plant technology, the rotating components of this invention use the most common, most easily obtainable types of bearing.
Thanks to their small size, many of the wind capture components (nos. 9, 10, 11, and 13 in particular, i.e. those most subject to wear) and other components can be more easily repaired in the event of failure or periodic replacement.
The 1 to 32 are elements of wind power plants; A,B conditions of work.
