Description

CONTEXT

An urban or domestic wind turbine is intended to produce electricity by capturing energy from the wind close to the consumer. It easily finds its place in the urban landscape, while offering a strong sympathy capital. Smaller in scale, it does not involve major civil engineering or wiring work. In particular, the vertical axis technology (VAWT, Vertical Axis Wind Turbine) is silent and robust with a lifespan of +/- 30 years. By capturing the swirling winds without casting an annoying shade, it can be installed in an urban environment or in a garden on a mast up to twelve meters or on a roof of a building without requiring a building permit and can also be mobile and portable when traveling, for example. The electrical production can be stored in rechargeable batteries, housed in the tower or at the foot of the mast and any surplus, be injected into the electrical network. Combining self-powered ancillary equipment with the production of energy allows it to be used for more functions (environmental measurements, lighting, display, service terminals, ...). With custom blades, painted or with a logo, for example, a VAWT can also be used, like a flag, as a dynamic communication medium, which, instead of floating, turns in the wind.

However, the small wind turbine is struggling to invest in the city where the wind deposit is less and intermittent. With limited efficiency due to max. of +/- 500 rpm and high costs for servicing and maintenance, it is not profitable. Used as a display medium, a high speed of rotation can also represent a drawback and add constraints and risks in a public environment (security, radio interference).

To address these issues, an associated technical device also collects solar energy and uses the luminous flux in the surrounding environment. Operating in combination with light (visible or not), without radio waves, in LIFI / VLC (Light Fidelity / Visible Light Communication), it optimizes its energy efficiency and allows the development of variable power models and designs. A small wind turbine is transformed into a renewable energy infrastructure "multi-source and connectable" to the electrical networks (Smart Grids, ...) and digital (Big Data, multimedia, ...). It thus opens up new perspectives for almost infinite uses and applications for small wind turbines.

Thus, the device can be associated with a tower (totem) with rotating panels or with one or more wind turbines limited / adjustable in rotation speed, such as the model in FIG. 1, 3, comprising one or more replaceable blade extension module (s) (9), thanks to jacks which can be mounted on the different axes with variable orientation, position and / or inclination (4) (4.1.) Of the system.

Thus said optical discs can be orientable, adjustable manually or automatically and connectable to each other and / or around one another and rotatable (at multiple levels and positions) via a system connected rods, gears and worms (not shown in detail).

The projector lamp modules (2.1) can be of variable type, functions (e.g. with cameras, sensors, ...) and designs, for example, flexible or rigid strips, strips or spots, with phosphors with their optics / reflectors (prisms / lenses, convergent / divergent), if applicable, powered by built-in rechargeable batteries.

Said sheaths connected by their end caps to the outer covering wall (fairing) to one or more light sources, namely optics facing the sun and / or lamps with LED / OLED and LIFI / VLC technology transducers (2.5 ) (routers / antennas), thus allow the combined and parallel transmission of variable signals (light and data) via the different fluxes / rays or light beams. These pass through one or more lenses and optical rings incorporated in the device, can be reflected, then processed / modified (filtered / sorted / deflected / diffused / focused / refracted / timed / encrypted) via one or more associated transducers.
