Definitions

  • This invention relates to a vertical axis wind turbine that captures and transforms wind power into mechanical energy for electricity generation.
  • a turbine spins on a platform that floats on the high seas. The wind will be picked up by high walls that taper it toward the turbine blades. Such walls will be fixed to the platform which will be circular in shape.
  • the platform which will be secured by cables at a point in the ocean, will rotate over the waters by the action of the wind together with a propulsion engine in the water.
  • the present invention incorporates a flotation system that can be used for the construction of marine platforms for various purposes. In this invention the turbine and the platform float over a layer of air over the water. Regardless of the weight of the turbine, this swing is suspended over the air, with no bearing pressure, and is significantly efficient. This is an invention to be developed and designed. It may be large or small.
  • FIG.1 a first example of the wind catchment system (fig.1) we have the round platform with the "Savonious" turbine with six blades in the center and two walls that taper the wind. These walls, which function as large deflectors, are positioned to give the turbine enormous performance.
  • One is in front of the turbine, at an angle that can vary between 45 ° and 60 ° degrees (dotted line), channeling the wind in favor of the rotation of the turbine, which in the drawing is counterclockwise.
  • This first wall also prevents the wind from colliding with the turbine rotation.
  • the second wall is at the bottom and to the right, having the same approximate angle of inclination and with curvilinear shape at the bottom, which enhances performance by giving great acceleration and force. Wind tunnel tests will certify the best performance angle as well as the optimal wind funnel.
  • the air is trapped inside maintaining the buoyancy.
  • the water while water pushes the air supporting the platform causing the float, the water also pulls the platform across its edge, keeping it level. Spinning will occur easily despite the large mass of concrete as friction and roughness will be minimal.
  • the format Pointed side has the function of breaking the waves of the sea.
  • the equilateral triangle outlines a gap in the concrete that will surround the platform and will be full of air, sealed against water ingress, minimizing sway and maximizing balance.
  • the construction can be done in a shipyard. After construction, the platform should be flooded. All air at the side edge should be removed. A valve system will maintain the buoyant pressure of water by removing all air. Inside, air should be blown until optimal flotation is achieved. It will then be hoisted to the location where it will be fixed.
  • the platform will be held in the center by a steel railing belt. These steel rails will form the belt that will surround the center of the submerged platform (fig.2) and the belt will be on a large steel float submerged in the ocean.

  • the turbine will be fixed by two bearings that will keep its axis aligned in the vertical position. This turbine will float on a layer of air having all the pressure of its mass there. There will be no pressure on the bearings and no wear on the bearings, and friction is insignificant regardless of their mass.
  • the present small invention it will not be for the sea but for land, and will not be made up of flotation systems, but only of the wind catchment system consisting of deflectors positioned to the front left and bottom to the rear. right of the turbine (fig.1) accelerating the rotor counterclockwise. It can be built in two ways: fixed in on top of a tower or on the ground. On a tower the deflectors will have free rotation and will always be upwind (fig.3). A rudder at the bottom goes up and down the height limits of the turbine as well as the deflectors. Rudder and deflectors will form a single piece, moving around the savonious turbine. On the ground the deflectors will move on a rail system around the turbine. An automatic control driven by electric motor will keep the deflectors always upwind.

Abstract

L'invention concerne une éolienne verticale destinée à être utilisée en haute mer et comprenant un système de flottaison la faisant flotter sur une couche d'air, d'où sa libération en termes de friction avec des pièces mécaniques mobiles. Cette éolienne comprend en outre un système de captage du vent captant une énorme quantité de vent et le canalisant vers la turbine en vue d'une rotation, tout ce système étant situé sur une plateforme océanique de béton qui flotte également sur l'air, d'où un maintien sûr et équilibré sous l'action de la force de poussée de l'eau.
