WIND POWER STATION IN THE FORM OF A SPOOL

Resumen de: WO2026172337A1

The invention relates to wind energy and represents a high-rise wind power station in the form of a spool with a large diameter and height. The main advantage of the structure is its high efficiency in wind energy conversion due to the aerodynamic flow around a large-diameter cylinder. The accelerated airflow increases the station's power output. The height allows for the utilization of stable wind currents with higher speeds, minimal turbulence, and longer operational periods. The upper side edge of the spool deflects airflow into the lateral area of the spool cylinder, where wind turbines of horizontal or vertical type, or a combination of both, are located in the form of flat wind-facing walls. These walls are formed by vertical and horizontal stiffening ribs, which are securely integrated into the station's structure. The spool cylinder includes rigid lateral surfaces for optimal airflow and sail elements in the front and rear sections, which automatically folding under critical wind loads to prevent structural damage. The station is adapted for placement on both land and water. Water-based versions are secured to the seabed using a swivel, while land-based variants can be either fully mobile on trolleys or have a stationary cylinder with rotating walls containing turbines. This design improves the station's orientation toward the wind direction.
