Description

Energy transformer mill TECHNICAL SECTOR The present invention falls within the field of mechanical energy conversion devices, and more specifically in rotation systems based on the principle of mass imbalance and buoyancy, applicable to the transformation of mechanical energy into electrical energy. BACKGROUND OF THE INVENTION Various devices and mechanisms exist that aim to generate continuous rotational motion from mass imbalances, buoyancy, or density differences between materials. However, these systems often have a complex structure that is very difficult to implement. The present invention proposes a new mill system with internal hydraulic blades that, through the use of interconnected floats displaced laterally from the axis of rotation, achieves a dynamic imbalance, thus generating a rotational movement. EXPLANATION OF THE INVENTION The mill of the invention comprises a set of arms in the form of blades mounted equiangularly distributed on a central axis of rotation anchored to a support structure only at one of its ends. Each blade or arm ends at its free end in a watertight tube or compartment filled with water, inside which there is an air-filled buoy, arranged so that it can move freely inside the compartment. The internal buoys are joined together by a system of ropes or cables of the same length, converging at a lateral anchor point offset from the central axis. This lateral connection point creates a controlled asymmetry in the distribution of forces, since the cable connecting the buoys is the same length. This forces the buoys to adopt a different position within each tank depending on the angular position of each blade, generating a different center of gravity for each element due to the greater weight of the water. Therefore, even though the blades weigh the same, the point of application of the force, and consequently the torque generated with respect to the pivot point of the assembly, is different due to the displacement to which the buoys are subjected. Because of their buoyancy, the buoys tend to move towards the highest point in each tank, so the off-center point of application where the cables are attached limits these buoyancy-related displacements and causes an imbalance between the buoys that generates a constant rotational torque.causing a continuous rotary motion around the central axis. The following advantages are derived from the described structure: It has a low environmental impact, as it can be installed underground, which would have a limited impact on the environment. Its implementation does not require hard-to-reach spaces, unlike other technologies (wind, hydro), so it can be installed at the foot of existing electrical distribution lines. Technology easily scalable according to the specific needs of each case. Do not generate any type of waste. BRIEF DESCRIPTION OF THE DRAWINGS To complement the description that follows and to aid in a better understanding of the characteristics of the invention, according to a reference example of its practical embodiment, a set of drawings is included as an integral part of said description, in which, for illustrative and non-limiting purposes, the following has been represented: Figure 1 shows a front perspective view of a power transformer mill made in accordance with the object of the present invention. Figure 2 shows a plan and cross-sectional view of the device at the level of the mill's rotation axis. PREFERRED EMBODIMENT OF THE INVENTION In view of the figures described, it can be observed how the mill of the invention includes a supporting structure (1) to which is associated a rotating shaft (2), to which is attached a helix-shaped structure in which a plurality of radial arms (3) are defined, in the embodiment four radial arms, equiangularly distributed, and which terminate at their free end in a radially elongated tank (4), in which a fluid (5) is established, such as water in which a buoy (6) is displaceable by buoyancy. The buoys in the chosen embodiment example have a cubic or rectangular prismatic configuration, without ruling out other configurations that have symmetry with respect to the axis (2) of rotation of the device. In any case, and in accordance with one of the essential characteristics of the invention, it has been provided that in proximity to the axis (2) of rotation of the blades, specifically offset horizontally with respect to said axis, an anchor point (7) is established to which a series of cables (8) of identical length are linked, associated at their opposite end to each of the buoys (6), this cable passing through the tanks (4) through watertight seals (9), or by using extensible / foldable corrugated tubes through which said cables run, thus avoiding the loss of fluid from the tanks. From this structuring, the horizontal distance between the axis (2) and the anchor point (7) forces the buoys (6) to adopt an off-center arrangement, as shown in figure 1, so that even though each of the blades weighs the same, the torque (p1) and (p2) generated by the blades will be different, being greater in those blades whose buoy is closer to the axis (2), thus generating an imbalance that generates a constant turning torque as shown by the curved arrow in figure 1. The device can be applied to the conversion of rotational energy into electrical energy by means of an alternator or generator (10) coupled to the main shaft. Optionally, the anchor point (7) may include positional adjustment means, to be able to move closer to or further away from the axis (2), depending on the specific needs of each case, and thus control the generated torque according to the specific needs of each case. Finally, it only remains to point out that, although in the chosen example the mill has four blades, the number of these can vary according to different design criteria, and they are distributed equiangularly.
