Description

DESCRIPTION

Vertical axis wind generator, with hanging blades

Technical sector

The sector of vertical axis wind turbines already exists, but it is varied in forms. The goal is to get the most out of the push of the wind, converting it into energy. All models try to reduce the resistance in the return of the turn and complete the 360° with force. Because the wind pushes, but it also slows down when it passes 180°. And it is about reducing this braking.

All models of existing vertical wind power generators work, but they do not take advantage of enough wind power to generate a useful amount of energy.

The contribution of this model makes it easier to turn the windmill, taking more advantage of the thrust of the wind, to convert it into rotation. And that the generator produces more energy. It is more cost-effective and can be used as an energy alternative to a higher level than existing models. In addition to being more economical to carry out due to its simplicity.

Background of the invention

Most of the existing models do not take enough force in the rotation due to their fixed system. Like the half cone or half sphere.

Others exist from a large and heavy vane that can only work in high intensity winds. Also some, with a gear system to position the paddles, which lose inertia due to the accompanying mechanisms. And other fixed coils. Although they all work, they are not strong enough for them to be marketed.

I have not found any model based on this contribution of multiple loose lightweight pallets. That notably facilitate the 360° turn by reducing the resistance in the return of the panels. More efficiency and benefit from the force of the wind is achieved.

Explanation of the invention

These are large panels assembled with many small movable paddles. The size of the panels can be from 1-2 meters, to sizes that can reach 5m. or more. The pallets of 20x30 cm. But they can be larger or smaller depending on the weight and wind of the place where it is installed. The contribution that differentiates it from other models is that the panels are mounted with these mobile paddles that swing in a single direction 80-90°. The reason for its operation is that these Palettes are made of very light plastics, of little weight, but resistant. Like foamed PVC, polyvinyl chloride or some other thermoplastic. The paddles are hanging on cross shafts. Next to it, there is another parallel axis that makes it possible to swing only the (±) 80°. They also have a bearing and a counterweight. All this makes it swing with just touching it or a tiny breath. This ensures that the air passes through the Panel and does not stop the rotation.

With the flow of the wind, the blades of a panel rise, and on the opposite side they are perpendicular to the air. Pushing and producing the rotation of the central axis that activates the generator.

The van panels are mounted adhering to the same axis and all rotate at the same time. They can have 2 or 3 panels on each floor, but it is preferable to have 3. With the half turn, the blades rise 80-90° in the opposite direction, allowing the wind to pass.

Description of the drawings

Figure 1. Shows the shape of the paddles from the front, side, and top. The illustration shows its placement with the T Stops, which limit its swing to an angle of X degrees. A counterweight, Z and R Bearings that facilitate its mobility.

Figure 2. Shows how Palettes and Panels would be placed to make it work. D is the fixed axis. C the mobile axis in which the panels are joined so that they all rotate at the same time. This shaft rotates the generator F. To facilitate the rotation of the mobile shaft, it has bearings, E. Also shown in image II, is the minimum assembly for full rotation to work. With 3 or four panels.

Application

It is so simple that it is easy to produce, maintain and repair. It is also practical, as it is a generator without additional costs. It is easy to market, because they can be made in many sizes. Manufacture easy-to-assemble designs. They can be installed on rooftops, country houses, factory roofs, farms, etc. They can be decorated with vinyl to be more artistic, or fulfill advertising functions.
