Description

DESCRIPTION

Vertical axis wind turbine powered by wind and sun.

The following invention relates to an electrical energy (current) generation system consisting of a small power (up to 50 KW.) vertical axis wind turbine with rotation assistance from a solar energy motor.

The vertical axis wind turbine consists of perimeter air collectors (fig. I.I) which have an inclined direction to collect winds of any direction and lead them towards the center of the structure where the semicircular blades are located (fig. 1.2). These wings (fig. 2) accumulate the air and begin to move rotationally supported on a shaft (fig. 1.3) which in turn begins to rotate giving movement to a motor (generator) (fig. 1.4) which is located on the axis of rotation. Rotating the generator (fig. 1.4) produces electrical power.

The energy produced by the generator (fig. 1.4), because it does not always have a constant voltage, is led with conductors (cables) to a voltage stabilizer-converter (fig. 1.5) which will convert the current into the desired voltage we want for charging batteries or for a direct power supply of some loads.

However, in case there is no air then with a small motor (fig. 1.6) which will be multi-turn, I will feed it from a photovoltaic panel (fig. 1.7) and it will move by transmitting its movement with a belt to the axis of rotation (fig. 1.3) who will in turn do what he did with the air. That is, it will rotate and thus the generator (fig. 1.4) will start producing current.

In case there is neither wind nor sun then we can have a battery which will charge from the photovoltaic panel (fig. 1.7).

The switching of the electric motor (fig. 1.6) will be supervised by an anemometer (fig. 1.8) which we will set when the wind stops at zero Beaufort to activate and start working and when the wind starts and reaches one Beaufort will disconnect it. The disconnection of the motor will be done as the bike idles, i.e. when there is air, the drive gear of the electric motor (fig. 1.6) will engage and thus the shaft (fig. 1.3) will turn freely without being hindered by the resistance of the electric motor [fig.1.6] which will have been stopped by the command of the anemometer [fig.1.8] and will be completely disabled. When the wind stops, the anemometer [fig.1.8] will start the electric motor [fig.1.6] which will start rotating, the drive gear will engage and the shaft [fig.1.3] will rotate which will start the generator [fig.1.4] and we will have electricity production.

In the case of the operation of the system with the wind, the production of electrical energy varies from one to the maximum amount and is variable due to the fact that the air does not always move at the same speed, while in the case that the movement is given by the electric motor [fig. .1.6] energy production is always constant [close to maximum].

Now as far as the construction material of the wind turbine is concerned, it will be entirely made of high-strength metal to be able to withstand the difficult conditions that prevail in the countryside.

The air collection sheets [collectors] [fig.1.1] will be able to be adjusted in their opening and closing mechanically so that we can achieve the maximum degree of air accumulation. Their shape will vary, depending on the requirements of the space and of each interested party, from square to circular.

The generator will be of the latest type with permanent magnets and a strong duralumin shell and the production voltage will depend on the requested power of each consumption.

The internal semi-circular sheets [fig. 1.2] will also be made of high strength sheet metal and at the top and bottom edges they will have sheet metal caps for better air entrapment but also for their stability at high pressures [overflow].

The photovoltaic panel [fig. 1.7] will be 300 watts as is the consumption of the electric motor [fig. 1.6].

The whole structure will be supported on a pillar [fig.1.9] which will have a cross-section of about thirty points and at the top and bottom it will have support flanges [fig.1.10] with a diameter of about one meter. All the construction of the pillar[fig.1.9] will be made of steel for the safe support of the machine

The rotation of the central shaft [fig. 1.3] will be done without any friction because it will be placed on bidet-type bearings which in turn will be placed on a special base [bearing] that you will be able to grease at regular intervals from the greasers that will have. The entire construction of the bearing will be sealed to prevent water and dust. Another important role that these bearings have is to be able to keep the shaft in a vertical position (fig. 13) so that it does not wobble and shake the entire construction. Also, due to the minimal friction that exists, the whole system is completely silent.

Claims (4)

1. A vertical axis wind turbine that does not need orientation because it takes advantage of all wind infiltrations and in case of apnea its rotation is done by a low consumption electric motor powered by a photovoltaic panel and battery. 2. A construction sufficiently resistant to stress due to the materials it is made of. 3. This construction does not need very frequent maintenance because almost no sensitive parts are aligned. And whenever it needs to be maintained it is very easy and can be done by anyone even unskilled. 4. A machine that can generate electricity almost twenty-four hours a day.
