Description

DESCRIPTION

Hybrid wind-solar wind turbine without blades

Technical sector

This equipment falls within the field of renewable electricity generation for domestic self-consumption in urban and rural locations, using wind and solar energy.

Background of the invention

No wind turbine is known to have solar panels in its structure to generate electricity for self-consumption.

There are many models of wind turbines of different sizes, powers and designs with vertical and horizontal axis, but none include solar panels that generate electricity in the same equipment.

There is a wind turbine with blades with a production capacity of 1,500 kWh (they say that the consumption of about 1,500 homes), located in the Breña wind farm in the province of Albacete near the Sierra de Alcaraz, which has solar panels on its tower to produce electricity to power some auxiliary systems of the wind turbine (keep the lubrication oil warm, orient the nacelle and protect it from strong winds...) but not for human consumption: https://elpais.com/videos/2020 -12-16/video-in-the-bowls-of-the-first-hybrid-wind-generator-with-solar-energy.html

Subsequently, this system has been used in other wind turbines located in Austria and Germany.

All these wind turbines have a large electricity production capacity compared to the equipment that is the object of this invention, which is smaller and is designed for self-consumption using all its wind and solar production.

There is a vortex wind turbine that is not really a turbine, since it does not rotate. It is based on the phenomenon of aeroelastic resonance that makes the device oscillate in the wind to generate electricity. It only uses wind energy and currently has little generation capacity: https://vortexbladeless.com/es/

There are offers on the market for differentiated wind-solar hybrid systems in two installations, not in a single installation as in this invention.

The problem with these models is that they have blades that harm the birds.

Also its noise level is high.

Due to these drawbacks, they are not the best option for domestic self-consumption.

Explanation of the invention

This invention presents a hybrid wind-solar bladeless wind turbine that is designed to produce electricity for self-consumption using wind and solar energy in the same equipment.

The equipment consists of a funnel-shaped body in a horizontal position that captures the wind through its widest mouth and expels it through the narrow one where a vane-type tail is located to orient itself against the wind.

The solar panels are attached to the upper part of this body.

Inside the body there is a frustoconical metallic piece attached to a tube by its smaller diameter that directs the wind captured by the mouth towards a narrower tube where a turbine that transmits its rotation to the electric generator is fixed with two bearings.

For this transmission, a pulley fixed on the turbine shaft is used, joined by a belt to another pulley located on the generator shaft.

The equipment is supported by a metal tube anchored to the ground that has a 360 degree rotation mechanism.

The electricity produced by the generator and by the solar panels is treated by power electronics to make it suitable for self-consumption and allows the joint use of wind and solar energy or only work with one of the two energies when the other is missing. The components of this power electronics (inverter, rectifier from alternating current to direct current, automatic voltage regulator, charge controller, protection and differential, wattmeter and bidirectional counter) are located inside the building or home where electricity is consumed. , thus being protected.

It has an application available on a computer, tablet or mobile for configuring the equipment and controlling production data, electricity consumption and discharge to the electricity grid. It can be programmed to work with or without storage batteries and to be connected to the Grid or work in isolated mode.

If you are connected to the network, you can pour the excess into it, charging for it, and receive electricity when you cannot generate all the necessary electricity.

The main advantages of this invention are summarized as follows:

• Allows the integration of wind and solar generation in a single unit. Wind and solar energy are often complementary. When one is missing, the other is usually there and sometimes the two energies are given at the same time, which is when maximum performance is obtained. The other wind turbines do not have this double generation capacity.

• Its funnel-shaped design accelerates wind speed and increases power generation capacity.

• It is specifically designed for self-consumption in urban and rural homes: - Its size is small with a compact shape that minimizes its visual impact.

- Complies with urban regulations.

- It is silent. It has few moving parts that are guarded.

- Respect the birds. It doesn't have shovels.

- Its maintenance is easy to carry out because the turbine is at a low height and only needs two periodic lubrication points.

- The generator does not need maintenance.
