Description

POWER GENERATING DEVICE Background of the Invention Field of the Invention
The present invention refers to a power generating device that can be implemented anywhere regardless of the wind conditions of the place. Description of the Prior Art
Wind-powered generating devices that convert mechanic power into electric power are known to those skilled in the art. They consist basically of a turbine that, by being actuated by the wind power, rotates the axle of a power generating device that finally turns the wind power into electricity.
Despite the advantages of this system, such as the production of clean power, its implementation is not possible anywhere, since it depends on the wind-power potential of the region, and in some places the winds do not suffice to assure the generation of power only by using such a system.
When searching a solution for this problem, the inventor has developed a mechanical power generating device, object of the Brazilian patent application PI0405558-6, that is comprised of a plurality of rods connected to a central axle forming a uniform radial assembly of rods, each one of which is comprised of a body that can be displaced along the length thereof in such a way that, when it is moved toward the rod end, it displaces the center of gravity of the actuating device by rotating same, thus generating power. The displacement of said bodies along the rods is carried out by either an engine or hydraulic cylinders, and the power used is that of the generating device itself.
The inventor has improved such a generating device by developing a power generating device, object of the Brazilian patent application PI0604246-5, that is connected to the free end of each rod, said generating device being capable of generating power to move said bodies along said rods, and the power excess can be stored for further use. This patent document discloses two ways for distributing the assembly of rods within the turbines, that is, a vertical one and a horizontal one.
In a less advantageous way, the vertical distribution of the assembly of rods still depends on the wind to make its turbines move, thus preventing its implementation anywhere. On the other hand, the horizontal distribution does not present a way to implement its movement, but only suggests the use of an engine to start its rotating movement.
Thus, aiming at the generation of power through the use of a wind-powered generating device in places where there is little or no wind at all, the present invention discloses a power generating device provided with horizontal rods having a self-standing actuating system coupled to the generating device, in such a way that it promotes the displacement of air masses, regardless of the presence of wind streams in the atmosphere.
Said connecting rods comprise turbines in their free ends, and when they rotate, with the aid of a low-power engine, the turbines rotate under the action of the displacement of air masses caused by the displacement of the assembly of rods, that is, there is no need to subject said assembly to natural wind streams, since it is caused by the displacement of the assembly itself. Brief Description of the Drawings
The principles of the present invention will be better understood from the following detailed description, made with reference to the accompanying drawings, which are provided as a non- limitative illustration of an exemplary power generating device incorporating the features of the present invention. In the drawings:
Fig. 1 represents a perspective view of a power generating device (10);
Fig. 2 represents an extended view of the detail A of figure 1; and,
Fig. 3 represents an extended view of detail B of figure 1; Detailed Description of the Preferred Embodiment
The present invention is directed to a power generating device (10) that is comprised of a supporting structure (4) in the form of a tower provided with a vertical beam (41) , and a central bearing (42) supported thereon, two rods (33) angularly distributed in a uniform way coming from same, each one of which provided with a turbine (3) in its end opposite the beam (41) ; a reducing motor (11) that promotes the rotation of the rods (33) ; and an electric power generating device (22) associated with the rotation of the turbines (3) . As illustrated in figure 1, the rods (33) come from a central bearing (42) that, concurrently with the reducing motor (11) , promote the rotation thereof, thus rotating all the rods (33) simultaneously. When the rods (33) rotate, they put the turbines (3) in contact with the air, thus rotating same, and, when they are contacted with the electric power generating device (22) , they turn mechanic power into electric power. Also, the power generating device (10) can be provided with three rods (33), so that they are spaced apart at an angle of 120°.
The size of the rods (33) and the turbines (3), the number of rotations of the assembly, and the pitch of the propellers (31) are varied in accordance with the amount of power desired. Said vertical beam (41) is hollow, and the structure (4) comprises a vertical axle (2) that is concentric and internal to the beam (41) and protrudes from the base (43) toward the upper end of the beam (41) .
The central bearing (42) is supported on the upper end of the vertical beam (41), the axle (2) crossing same. The rods (33) protrude from the central bearing (42) with the turbines (3) in the free end thereof and opposite said central bearing (42) .
Since the central bearing (42) is supported on the upper end of the beam (41) and crossed by the axle (2) , it can be rotated freely, thus allowing the rods (33) actuated by the reducing motor (11) to rotate freely as well.
As illustrated in figures 1 and 2, a reducing motor (11) is conveniently coupled to the central bearing (42) , thus making the central bearing (42) to rotate concomitantly with the rods (33) . At their ends, said rods (33) are provided with a supporting base (333) for bearings (35) that receive the horizontal axle (32) that comes from the turbine (3) . The transmission of the rotation from the turbines (3) to the generating device (22) can be carried out by any way known in the prior art, such as crankshafts, gears, belts, and the like. According to the example shown, the transmission is carried out by means of a belt, wherein said axle (2) is comprised of an upper central pulley (21) that receives the belts (34) , each one of which is associated with the axle (32) of a turbine (3) , in such a way that it transmits the rotation of the turbines (3) to the axle (2) . The axle (2) is associated with a generating device (22), that in this case is positioned at the base (43) of the structure (4), so that the rotation of the axle (2) generates electric power.
In a preferred way, the rods (33) are perpendicular to the axle (2) of the structure (4), thus making it easier to install and move the belt (34) , thus not requiring the use of intermediate pulleys for eventually change the direction of the belt (34) . In the example shown, the rods (33) comprise intermediate pulleys (331) that are distributed along the length thereof, so that the belt (34) can pass through same, thus preventing same to buckle between the axle
(32) and the central pulley (21) . Said rods (33) are associated with one another by means of an upper pyramid-shaped structure (5) that protrudes from the rods
(33) and is centered in relation to the axle (2) . On top of the structure (5) there is a pair of cables (6) for each rod (33) that are extended as far as the bearings (35) thereof, in such a way that the weight of the rods (33) themselves is compensated for, thus preventing same to buckle, what could compromise the movement of the belt (34) and the stability of the assembly. The present device can be installed anywhere, and the displacement of the air caused by the wind is replaced by the displacement of the rods (33) promoted by the reducing motor (11) that, by rotating the rods (33) , moves the turbines (3) against the air, thus rotating its propellers (31) and its axle (32) . The belts (34) transmit the rotation of the axle (32) of the propellers (31) to the pulley (21) that rotates the axle (2) associated with the generating device (22), that then turns it into electric power.
The positioning of the generating device (22) can be any one, either together each one of the turbines (3) , or associated with the upper portion of the axle (2) , or still associated with the axle (2) at the base (43) of the device (10) as illustrated in figure 1.
While the invention has been described in terms of its preferred embodiments. Those skilled in the art will recognize that the invention can be practiced with modification within the spirit and scope of the appended claims.
