DESCRIPTION

Fluid-mechanical drive unit

Technical sector

The present invention refers to a system for the use of natural energy or Renewable Energy.

Background of the invention

In Renewable Energies, natural energy sources such as the sun, wind, hydraulic jumps, tides, can be examples of the least polluting ones, where transformation and exploitation means are used, normally destined in a greater proportion to the generation of electric current. . They are known as clean energies that seek to reduce or cancel the environmental impact and the emission of waste, although they can present problems of difficulty of accumulation, cost overruns, damage to fauna, environmental impact and interruption due to the particular characteristics of each source and each transformation medium.

Explanation of the invention

The Fluid-Mechanical Drive Unit is a device that, immersed in a fluid, generates rotary movement under the action of a driving torque.

Rotational energy is obtained from the thrust of submerged volumes of air. Several mechanical components of coordinated and harmonized action intervene during the movement generated in the set.

Some cylindrical capsules, articulated on a transmission chain that joins two rotating wheels and spaced under uniform distribution, have membranes at their ends in which the hydrostatic pressure intervenes and produces a resultant force. The displacement of these membranes allows the volume of the capsule to change. The force acting on the membranes can be considered negligible when the capsule is located close to the surface and increases with the depth to which it is submerged. This force acts, at the same time, on a transfer mechanism that allows interaction with the radial thrust and displacement experienced by a hollow, watertight container and therefore of constant volume.

In this transfer mechanism there are springs that use their potential energy when they change their length, resulting in another load that acts in the same direction as the resultant exerted by the membranes.

The change in radial position of the constant volumes occurs when each capsule reaches the position of greatest and least depth, as well as the displacement of the membranes and therefore the change in volume of the capsules. The capsules that are located in the upward direction have the constant volumes at a greater radial distance than the capsules that are located in the downward direction. On the other hand, the displacement of the membranes has been carried out in such a way that during the upward movement, the capsules have a reduced volume; and during increased downward movement.

The moment produced by the thrust force of the constant volumes, due to their different radial position, is always in the opposite direction and of a value greater than that produced by the increase in the volume of the membranes, resulting in a torque and rotary movement with the imposed direction. by the upward movement and the greater radial displacement of the constant volumes.

The resultant in the membranes due to the hydrostatic pressure is used as the driving force, which, in the greatest depth, exceeds the spring force and the constant volume thrust. It causes the radial displacement of the constant volume and reduces the volume of the capsule.

When the capsules approach the surface, in the upper position of the circular path, the force exerted by the constant volume is less than that transferred by the spring. The constant volume reaches the smallest radial position, instead the membranes are expanded and achieve an increase in volume in the capsule, but the moment produced is of a lower modulus and exceeded by that achieved in the opposite direction due to the greater radial displacement of the volumes. constant. In this position, the force due to hydrostatic pressure on the membranes is very low or practically nil, as the capsules reach the position closest to the surface. However, it is overcome by the force of the spring and the downward journey begins. At the end of the downward stroke, the same sequence described above is repeated for each capsule that is located deeper, generating another actuation cycle with generation of the driving torque and movement.

Preferred embodiment of the invention

As a model to be carried out, and that serves for the analysis, evaluation of properties, behavior and characteristics, in order to be able to be an instrument for its better development and optimization, this Fluid-Mechanical Motor Unit consists mainly of:

Two wheels (1), which are arranged on their axes of rotation and bench, not represented. The rim of each wheel (1) is machined into the semicircular housings (2) that allow the transmission chain (3) to be connected. In the transmission chain (3) the supports (4) are located where they are connected, in their central joint, each capsule (5). At each end of the capsules (5) there are two lateral membranes (6). Each lateral membrane (6) is attached to its fixed base (7) by means of the ring (8). The drive shaft (9) is attached to each lateral membrane (6) through its central hole, and connects in an articulated way with the scissor mechanism (10).

The scissor mechanisms (10) and the radial actuator (12) are located, next to the springs (11). The radial actuator (12) connects with the central membrane (13) and the lever (14) and at whose end the constant volumes (15) are located.

The force of the springs (11) is greater than the thrust made by the constant volumes (15), through the scissor mechanism (10) in the position of the capsules (5) closest to the surface. The constant volumes (15) change from the largest to the smallest radial position. In the most submerged position, the hydrostatic pressure on the lateral membranes (6) produces a force that is greater than that exerted by the springs (11) plus the transfer of the thrust of the constant volumes (15) and the force, by hydrostatic pressure , in the central membrane (13).

The distance between the wheels (1) is sufficient for the hydrostatic pressure on the membranes (6) and (13), at the greatest depth, to produce the force that exceeds the joint action of: constant volumes (15), force of the springs (11) and force on the central membrane (13).

The supports (4) allow the rotation of the capsule (5) that manages to align the thrust center of the constant volumes (15) as close to the transmission chain (3) in the downward path, and they are positioned with the same angular displacement, but in the opposite direction, during the upward travel, allowing a greater radial distance of the constant volumes (15).

This greater radial distance, in the upward position, is effective when the supports (4) make contact with the wheels (1), generating the drive torque of the unit.
