DESCRIPTION OF THE INVENTION

The invention concerns a wind turbine with a rotation around the vertical axis.

It has been for many years the energy needs for economic needs are constantly increasing, while the currently used energy sources for the most part are exhaustible and non-renewable and polluting sources.

In order to be able to not only get more energy, but also protect from pollution the environment, are constantly carried out numerous studies aimed at the development of systems to produce energy natural and environmentally friendly ways.

Wind energy, which is a part of the energy resulting from movement of air relative to the ground, and which can be intercepted and converted into other forms of energy by means of a rotating under the action of the rotor of the wind, is one of these natural and non-polluting energy sources.

Wind energy is used by man since time immemorial in the windmills intended for grinding grain. It was found significantly after possible conversion of wind energy into electrical energy by means of electric generators, rotating windmills. However, this form of energy is not widespread due to low productivity and low efficiency of wind power plants.

There are two types of wind turbines. The most widely used wind turbines of the first type, in which under the action of the wind rotor rotates around a horizontal axis. These wind turbines have been the subject of numerous studies aimed at their improvement. Such wind turbines may be used, for example, to recharge batteries or to produce electrical energy.

The second type of wind turbines, in which the action of the wind rotor rotates about a vertical axis, but where the blades are set at an angle of specially selected, which allows such wind turbines rotate at wind occurs. Wind turbines of this type are mainly used for the production of electrical energy.

Although these wind turbines produce energy natural character and do not pollute the environment, they have not sufficiently known, in particular, due to the fact that they are still today have a number of drawbacks, some of which will be listed below.

These wind turbines require large areas on the ground for their rotation as the blades, although few in number, cover a large area. Consequently, this type of wind turbines can not be installed on the ground close to each other.

The blades of wind turbines have to be very large and very wide to the engine developed a large enough capacity.

Wind turbines can only be used in open spaces, where the winds are of sufficient velocity to drive the blades to rotate.

Zone blades lapped by the wind is too small in relation to their volume, whereby their efficacy is limited.

The movement of the blades in the air limits the speed of rotation.

The rotation of the wind turbine yaw does not allow a large number of blades, as it causes perturbations in the rotational motion.

Due to the great height of the wind turbines it is impossible to carry out maintenance work directly on them. Consequently, the maintenance-free wind turbine has to be dismantled to perform the corresponding operations on the ground, which makes maintenance operations very costly.

The wind direction has a great influence on the rotation of the blades of wind turbines.

If wind blows with sharp gusts, wind turbine blades mechanical strength may be insufficient, which can lead to their destruction, as they are mounted on the sleeve only at one end and a surface which is exposed to strong winds, is insufficient strengthened.

The direction of rotation of the blades of the wind turbine depends on the wind direction. This means that the blades can be rotated in two opposite directions. Clearly, this is inconvenient for the normal electric power generation as requiring special additional devices, enabling normal operation of the electric generator at any rotational direction of the blades, which reduces the efficiency of the wind turbine.

The purpose of this invention is to provide a wind turbine which does not have the above drawbacks of the known wind turbines.

Wind motor according to the invention comprises a rotor rotatable by the wind on its vertical axis in relation to the ground, and a rotary shaft which can be driven in rotational movement by said rotor and which is able to transmit the mechanical energy generated rotor (see. FR 2298706 A, 24.09.1976, Figure 1) -. prototype.

The proposed wind turbine is characterized in that its rotor comprises a hollow inside the body having a generally cylindrical shape, whose wall mainly formed blades disposed vertically so that a moving air stream or air was able to enter the inside of said hollow cylindrical body to the lead body into a rotary movement and thus bring the rotation of said rotary transmission shaft with which it is associated.

This hollow inside of the cylindrical body can comprise one or more superimposed and rigidly interconnected cylindrical elements, each of these elements comprises a lower circular rigid portion and a top circular rigid part, between which are secured in a vertical blade position forming an ordered set, or number of blades.

In a preferred embodiment, the hollow inside of the cylindrical body is composed of at least one first cylindrical member comprising a lower circular and rigid member, the center of which is rigidly connected with a gear rotating shaft and an upper circular and rigid part, between which are fixed in the vertical position of the blade forming the first ordered set or a series of blades.

This hollow inside cylindrical housing may further be composed of a second cylindrical member comprising a lower circular and rigid portion rigidly connected to said upper circular and rigid part of the first cylindrical member and the top circular and rigid part, between which fixed upright blade, forming a second ordered set or a set of blades, located on the first row of blades.

The top is round and hard part of the first cylindrical member and the bottom is round and hard part of the second cylindrical member can be one and the same round and rigid element.

This hollow inside cylindrical housing may further be composed of a third cylindrical member having a bottom circular and rigid portion rigidly connected to said upper circular and the rigid portion of the second cylindrical member, and an upper round and stiff element between which fixed upright vanes forming a third ordered set or a set of blades, located on said second row of blades.

The top is round and hard part of the second tubular element and the bottom is round and hard part of the third cylindrical member can be one and the same round and rigid element.

Now, the invention will be described in more detail with reference to the annexed single exemplary figure.

In this single figure schematically shows a preferred embodiment of a wind turbine in accordance with the present invention.

Wind turbines with a rotation around the vertical axis

The diagram FIG wind engine according to the invention comprises a hollow inside the body 1 of generally cylindrical shape, which are formed by blades sidewalls 2a, 2b, 2c, mounted in a vertical position so that a moving air flow, or air could enter into the said hollow cylindrical body to cause the body 1 into a rotary movement and thus cause the rotary motion into rotary transmission shaft 3 to which the body is rigidly connected.

In the schematic FIG embodiment, wind turbine according to this invention inside a hollow cylindrical housing 1 consists of three cylindrical bodies 4, 5 and 6.

A first cylindrical element 4 and comprises a lower circular rigid member 7, the center of which is rigidly connected to the rotary drive shaft 3 and a circular top and a rigid part 8, between which are secured blades upright 2a forming the first row of blades.

In this embodiment, a round bottom and said rigid member 7 of the first cylindrical member is a solid disc. However, in other cases, the possible implementation of the bottom round and the rigid element of the first cylindrical element may be an element of round spoked containing sleeve rigidly connected to the driving rotary shaft 3.

The second cylindrical element 5 comprises a lower circular and rigid part 9 rigidly associated with the upper circular and the rigid part 8 of the first cylindrical member 4 and the upper circular and rigid body 10 between which are secured in a vertical position 2b vanes forming the second row of blades, positioned above the first row of blades 2a.

The third cylindrical element 6 comprises a lower circular and rigid portion 11 rigidly connected to the upper circular and the rigid part 10 of the second cylindrical member 5 and the top circular and the rigid part 12 between which are secured upright vanes 2c, forming a third row of blades positioned above the second row of blades 2b.

It should be noted that the upper circular and rigid part 8 of the first cylindrical member 4 and a lower circular and rigid part 9 of the second tubular element 5 which are rigidly connected to each other, may represent two different circular element rigidly attached to each other or a common round element.

Moreover, the upper circular and rigid portion 10 of the second cylindrical member 5 and the lower circular and rigid portion 11 of the third cylindrical member 6, which are rigidly connected to each other, can be either two different circular element rigidly attached to one another, or a single common round element.

Necessary and noting that round the rigid portion 12 forming the upper part of the hollow inside of the cylindrical body 1 may be either a certain round element such as a ring type, leaving the top of said cylindrical body 1 is open or circular element type solid disc covering the top of the barrel 1.

It has already been described as an example of a wind turbine in accordance with the present invention, wherein the cylindrical body 1 is composed of a first cylindrical element 4 over which is fitted and is rigidly connected thereto a second cylindrical member 5 and the third cylindrical element 6 forming together a single the cylindrical body of the wind turbine.

However, it should be noted that said cylindrical body of the wind turbine 1 according to the invention may comprise two or more cylindrical elements 5 and 6 mounted on top of said first cylindrical element 4.

Further, the cylindrical body of the wind turbine 1 according to the invention may comprise, for example, only one or a first cylindrical element 4, a first cylindrical element 4 and the second tubular element 5, located on top of said first tubular element and rigidly associated with it.

The fact that according to the invention it is possible to install on each other and rigidly link the plurality of cylindrical elements allows to increase the size of the barrel 1 while maintaining adequate levels of its mechanical strength, but also allows for stabilization of the blades 2a, 2b, 2c at high speeds of rotation of the cylindrical body 1 in the case of strong wind.

Furthermore, it can improve the capture of wind cylindrical body, thereby increasing the strength of the centrifugal force and with respect to this force.

Also, the above-mentioned circumstance increases the efficiency of the wind turbine, since it must be noted that the large size has a cylindrical body, said wind turbine, the more power it can develop. In addition, the said circumstance and facilitates maintenance of the wind turbine.

The amount used in the wind turbine blades varies, depending on the requirements imposed on it, and will increase with increasing diameter of its cylindrical body.

The cylindrical body of the wind turbine in accordance with the present invention may be made of various materials, but corresponding to one single request which is appropriate to the material had sufficiently high tensile strength at perhaps a lesser specific gravity.

In fact, used to produce the elements of the wind turbine in accordance with the invention, the materials of construction must have a sufficiently high mechanical strength to safely withstand the pressure of maximally strong winds possible in a given area, and air pressure changes within said cylindrical housing of the engine, and these construction materials should be easy enough to make good use of the largest part of the amount of motion forming the air flow with the wind in order to ensure the best efficiency of the wind turbine.

blade wind turbine mentioned above, in accordance with the present invention can be installed in its cylindrical housing at a certain specific angle so that when the air flow will enter the inside of said cylindrical body, bringing it into a rotational movement, there is created a certain pressure difference between the the two parts of the cylindrical housing, which will increase its rotational speed, and hence developing the data output wind turbine.

Wind turbines in accordance with the present invention has many advantages compared to the known exploits and now wind turbines. Below these advantages will be set forth more concretely.

Said cylindrical body of the proposed wind turbine in the wind rotates around its vertical axis, which can significantly reduce the size of the space required for its operation. Thus, compared with existing designs of wind turbines on the same area can be used more and more wind turbines use wind energy and more effectively and hence produce more useful forms of energy, such as electricity.

Since the blades of the cylindrical body of the proposed wind turbine mounted in an upright position, they are set at the same angle over their entire height, which provides the best conditions for the capture of wind and consequently increasing the efficiency of the wind turbine.

Due to the fact that the blades of the proposed wind turbine located in an upright position, it is possible to install a greater number of blades than in existing designs of wind turbines, thus increasing the amount of air used for driving of the wind turbine into rotational motion, thereby increasing the efficiency of air currents or wind.

Since the cylindrical body of the proposed wind turbine can be rotated about its vertical axis, it is rotationally driven in any direction of the wind. Thus, the wind direction has no influence on the rotation of the wind turbine.

Since in this case the two vanes are secured at their ends, they are much more efficient and much more durable than the known wind turbine blades.

In the case where there is a movement of air flow, i.e. blowing air, it penetrates inside the cylindrical body, and due to the presence of blades leads it into rotary motion, causing the rotationally driven rotary transmission shaft 3, which acts on the gear 13 in order to form a movement suitable for use either for direct actuation of a mechanical device, or to generate electrical energy.

Thus, the wind turbine according to the invention can be used, for example, to generate electricity for charging batteries or for actuation of a pump.
