A wind energy catchment device comprising a central vertical shaft that rotates, the bottom end of which is secured by means of bearings to a rigid support fixed to the ground, the upper and lower part of the shaft have radial arms secured to it, evenly spaced one from the other, the outer ends of the upper arms are connected by cables or cords with its contiguous outer ends of the lower arms, between the upper and lower radial arms and the central shaft there are rectangular parallelepiped sails secured at their outer vertices. In all cases the furthest external vertical side of these sails or plates is secured and the sails or plates rotates from 90° to 180° with or around their shafts, cables or ropes that connect the ends of the arms, having both internal vertices loose, between the central shaft and two contiguous arms are arranged some parallel cords or mesh that support the sails or plates when they receive the air on the side of the mesh furthest from the wind.
