Abstract

Underground wind generator. The object of the invention is to generate electric power by wind generators, below the buildings. The tubes (1) lead the wind from the upper end of the building to the basement (3) where there are the wind generators that produce the electrical energy, leaving the wind channeled by the outlet pipes (2). The consequence is a substantial reduction of the noise produced by wind generators at high speeds, a lower visual impact of the building, greater security for both people and birds because the generators are in a closed compartment (3) as there are no propellers dangerous at high revolutions on rooftops or high parts. An important alternative is that the upper part of the tube (1) is made of a transparent plastic material to have a lower visual impact.

Description

Underground wind generator.

The present invention relates to a generator underground wind, thanks to which a reduction is achieved substantial noise produced by wind generators at high speeds, lower visual impact of the building, and greater safety for both people and birds, because they are generators in a closed compartment (3), as there are no propellers dangerous at high revolutions on rooftops or places high.

Background of the invention

Wind generators are known for electricity production. They are of different size and different nominal powers. They generate electricity for homes isolated, telecommunications towers, or any demand electrical they have to cover. They are very reliable in operation, And they work day and night. But they have some drawbacks. The wind generators, as the wind speed goes increasing, they feed the power they supply exponentially, but the decibels of the radius of the propeller, which can sometimes be a sharp and constant whistle, causing discomfort in the home itself or third parties. Also, if the wind blows at night, the problem worsens, being able to affect the sleep of some people.

Wind generators must be installed in high places for optimal performance. How much more high are on the ground, less wind turbulence les they will affect, and the wind speed increases considerably. For get the required height, they are usually mounted on posts Special metallic for this purpose. These posts are difficult to assemble, and very laborious when they have to be deployed and disassembled to access the wind generator to repair it or to perform a technical maintenance.

Because they are installed high, they cause that are seen with the naked eye from near or far places, with the consequent visual impact they can cause.

The propellers of a small or medium generator, they turn at a high speed when the wind is Moderate or strong This blade speed can be dangerous for birds, or for people who might have access to the generator

When the wind speed is very high, and exceeding the nominal speed of the generator, there is a risk to The wind generator itself. Normally the generator manufacturer wind, designs some system so that the generator itself disorienting or braking automatically, causing that excess of wind energy in the atmosphere, be wasted. If I dont know slow down or disorient the generators, it would cause breakage by an excess of revolutions, with the corresponding risk that any living being, was reached by some piece of generator that fired from it.

The underground wind generator applies by first time, a system that substantially improves the background to the invention of the underground wind generator, canceling all drawbacks mentioned in this background section, and providing more advantages that are detailed below.

Description of the invention

The underground wind generator provides for the first time an underground electric power generation system, which differs from the wind power generation facilities carried out so far, which are installed in high places or locations. The underground wind generator works under a building, in a subway. The wind energy is channeled through a set of metallic tubes or transparent plastic material, whose diameter must be somewhat larger than the diameter of the wind generators that will be installed for each tube, and said tubes will be installed in the most high of a building. The orifices of the wind air inlet must face the wind, and perpendicular to the horizontal, and be focused in the direction where the winds blow statistically most times a year. In the case that some day, the wind direction is not exactly what the inlet holes of the tubes have, but very close, the wind air will also be channeled entering inside the holes of the tubes, due to the "run" that have the tubes at the rear of the installation, where the air comes out, after having previously passed through the wind generators of the
Underground.

The air is channeled through the holes of the tubes, following a curvature of the 90º progressive tubes in the form of a quarter of a circle, which sends the air towards down the building by pipes that descend into the basement by The interior of the building. Before reaching the basement, there is another 90º progressive curvature of the tubes in the form of a quarter of circumference, which sends the air horizontally to where there is the colic generators located in the basement, making the generator propellers begin to turn more or less revolutions, depending on the speed of the next air channeled through the tubes. The air after having passed through generators, follow its path through the pipes, and immediately there are another curvature in the 90º progressive tubes in the form of a quarter of circumference, which sends the air vertically towards the outside, going outside again, finishing his travel.

The first consequence of the system is that it is extremely quiet when the generator is in a basement with a acoustic insulating material.

With the underground wind generator we decrease the urban visual impact of a building because the tubes and 90% of The entire facility is inside the building. The tube that is in The upper outer part can be transparent hard plastic achieving a high degree of invisibility of the tubes from the public road.

The underground wind generator avoids risks for public roads because the installation is in a basement and not in the High part of a building.

The underground wind generator can also be applied in isolated rural or mountainous systems, mainly to avoid a risk to birds, less visual impact placing a hard and very transparent plastic tube, and a smaller time to repair or replace the generator because what is truly elevated, it is the tube and not the generator, which found in a booth or underground.

With the underground wind generator we can get less cleaning maintenance, by being in a basement or booth. Bird and insect droppings are prevented from being deposited killed in the wind generator's propellers, which can affect the aerodynamics of the propeller blades, decreasing the generator revolutions and even cause a weight difference of the blades with each other, and destabilize the entire generator causing dangerous vibrations when it reaches a speed of revolutions determined.

The underground wind generator supports and regulates excess wind to avoid damaging the generator due to excess wind, and at the same time can take advantage of the excess d? Energy wind while the generators that are in the outside are not able to harness that energy, they don't even arrive to produce almost electrical energy, because they become disoriented or stop. With the underground wind generator, you can simply stop the excess air flow entering the tubes, through a manual or automatic gate located in the exit hole of the air, regulating the opening passage of the outlet opening, and regulating as a consequence the revolution of the blades of the generator and regulating the amount of electricity desired. From This mode can take advantage of energy when there is wind strong.

An important alternative is that the elbow of the upper part of the 90º progressive tube, by means of a rear helm and a moving elbow joint, the upper hole perpendicular to the surface, focus facing the wind automatically by the same helm. In this way, the generator underground wind is better suited in geographical locations where Wind directions may be more variable.

Description of a preferred embodiment

The underground wind generator (3) of figure 1, It works under a building, in a subway. Energy wind, is channeled through a set of metal tubes (1) or transparent plastic material, whose diameter, must be something greater than the diameter of the wind generators (6) of figure 5. The wind air inlet holes (1) in Figure 2, they face the wind, and perpendicular to the horizontal, and focused on the direction where statistically blow the winds most times a year. In the case that one day determined, the wind direction is not exactly what they have the entrance holes of the tubes, but very approximate, wind air is also channeled by entering inside the orifices of the tubes, due to the "run" that the tubes have (2) of figure 2, at the rear of the installation, where the air comes out, after having previously passed through underground wind generators (3) of figure 2.

The underground wind generator (3) of figure 6, is protected with acoustic material (5) of figure 6, to avoid the aerodynamic noises that generators produce when they roll at high revolutions due to the pressure and speed of the ducted air circulating through the tubes (1) and (2) of figure 2 and (4) of figure 5.
