METHOD FOR CREATING THE EARTHWORKS FOR THE FOUNDATIONS OF A LAND-BASED WIND TURBINE

NºPublicación: EP3938583A1 19/01/2022

Solicitante:

CTE WIND CIVIL ENG [FR]

WO_2020182957_A1

Resumen de: WO2020182957A1

The present invention relates to a method for creating the foundation earthworks designed to form a pedestal for a land-based wind turbine, comprising a step of excavating, in the ground (S), a recess (Rf) intended to accommodate, on the one hand, an anchoring means (Cg) that will be used to anchor the mast to the future foundation and, on the other hand, the pouring of concrete (B) to form, once it has hardened, said foundations. According to the invention, the method consists: - in digging an excavation (Dc) in the middle of the recess (Rf) , - in placing a compressible material in this excavation (Dc), - in covering said material with a layer of concrete (Bt3) and in waiting for it to harden. An earthworks created in this way makes it possible to construct the foundations for a wind turbine, notably by the pouring of concrete, and the central part of which does not press into the ground or presses only negligibly into the ground. The result of this is that the ground pressure is increased onto and delimited by a peripheral annular region situated around its central part. This annular load distribution allows the foundation to accept greater eccentricity in the loading. It therefore becomes possible to reduce the diameter of the foundations, and to reduce the volume of concrete involved in their manufacture. The resistance of the foundations to lifting during operation of the wind turbine is maintained.

WIND-POWERED CYCLO-TURBINE

Nº publicación: US2022010776A1 13/01/2022

Solicitante:

GRATZER RICHARD L [US]

EP_3885574_A1

Resumen de: US2022010776A1

A mechanical device system that draws power from the wind by means of near-vertical blades pivotally mounted on a platform rotor that is flush with the ground and rotatable about a vertical axis. Wind forces are generated on the blades causing the platform rotor to turn thereby generating shaft power. An electrical generator coupled to the platform rotor converts the shaft power to electrical power, which is then distributed through conventional transmission means. The power output is maximized for a given wind speed by cyclically controlling each blade rotation to intercept the relative wind vector so as to create maximum blade forces over the periodic cycle. The blade axes are canted to match the rotational speed to the normal speed gradient of the prevailing wind to maintain constant (π*h*D)/Vw at all levels. The turbine is mounted atop an earth mound tailored to accelerate the flow near the ground to produce an optimum wind speed profile. The rotor speed is controlled to match the wind speed within narrow limits for maximum efficiency and power output.
