Description

HYDRODCINETIC TURBINE, TO PRODUCE KINETIC ENERGY AND TRANSFORM IT INTO ELECTRICAL ENERGY THROUGH THE PRESSURE FLOW AND VOLUME OF WATER "

Background of the Invention

A hydrokinetic turbine for the generation of clean renewable energies, equipped with a plurality of prismatic chambers arranged at different angles and determined positions to produce kinetic energy through a flow of pressure and volume of water to transform it into electrical energy with the incorporation of a Neodymium alternator, more specifically, the invention is provided with structural means to more efficiently channel river water or the like, flowing through the turbine bodies.

With regard to the state of the art for hydrocinatic or hydraulic turbines, to produce electrical energy, we can cite the patent of invention ES2 395 B88 Al. Which refers to a hydraulic turbine with tilting blades for the bi-directional use of flows than. being of the type comprising an impeller (2) consisting of a body rotated by its axial axis (3). to whose central perimeter area a plurality of blades (4) are attached. said impeller (2) being incorporated in a cylindrical housing (B) and connected to a multiplier box a (ID) that is connected to an electric generator (II) by means of a flywheel (12). It is characterized in that the impeller (2) is configured as a symmetrical body perpendicular to the axial bearing (3) that allows it to work in both directions of operation; because the blades (4) are coupled to said impeller (2) by means of a radial rotation axis (5) with a tilting movement that allows their position angle to be varied so that the leading edge of said blades (4) changes orientation , depending on the direction of flow; and because each vane (4) has a symmetrical cross section configuration.

Another patent for invention is ES255I756, which refers to an interposition hydraulic turbine, essentially, characterized in that it consists of the following parts or elements: a volute (I), with internal channeling in five spirals (3): a fluid inlet (2). and another output (9). both threads (II); An impeller (4) that has a unique geometry that characterizes it, with a semi hyperboloid shaped body, with blades (5) shaped like a hyperbolic paraboloid, which incorporates an optional conical diffuser (8). in its previous part. It also incorporates a shaft (8). with its bearings (10), and an electric generator (7) located on the opposite external.

Another patent is ES2D89798T3, which refers to a hydraulic turbine comprising a water supply conduit and a rotating impeller (IÓ) provided with a plurality of 'blades (II). with a transition member {12; 29; 33) mounted downstream of the impeller (10) to channel the water flowing through the turbine blades; characterized in that the transition member (2D; 33) is mounted independently of the rotation of the impeller (10). The advantages of the hydraulic turbine of the invention are as follows:

• Due to the structural conformation and arrangement of the prismatic chambers, it significantly improves the entry and exit of water while the turbine is rotating. • The chambers that receive the flow and speed of the water counteract the losses suffered by blows at the entrance of the water and loss by counter forces at the exit while the turbine is rotating, which is achieved by significantly increasing the rotation speed of the turbine and lowering noise level, vibrations and duration of components.

• The chambers that receive the water flow, water pressure and speed cut and penetrate the water inlet, making better use of the flow and increasing the volume of water received, thus achieving an exceptional increase in torque and force in a central transmission shaft of said turbine.

• By having a low speed neodymium alternator, no high speed is required to generate power

• The power transfer system and. the speed transmission, are covered with a container and arranged outside the water, which is self-lubricated, which allows a longer useful life of the hydrokinetic turbine.

• The turbine unit has the ability to self-level in the water at the optimum height, for greater trebejo efficiency, according to the flotation system, where it can be used in a floating way in rivers or channels, in addition to operating stationary through a jet of water under pressure or gravity flow.

• L ^'to hidrocinática turbine is maintenance free for one year and only needs lubricating bearings on central driveshaft once a year. • The hydrokinetic turbine has protection covers that remain at the water level, to avoid ingesting stick branches or garbage when it is in operation.

• It is transportable, since you can change places to find the best flow in the river.

• It is not necessary to alter the flow of the river, or make any modification or alter the environment of a place, so that it can be operable.

• This turbine is friendly to the environment, since it does not pollute the waters it uses to operate.

• The chambers can be both fixed and can also be moved mechanically by gravity in order to increase the distance between said chamber and the central axis of the turbine's power transmission, with this being achieved, increasing and even doubling the torque and force transmitted to said axis, depending on the depth of the water where it is operated.
