Definitions
- the present invention falls within the field of renewable energy production systems, specifically in the field of hydroelectric energy and devices for generating energy from water currents in rivers and seas.
- renewable energy An example of renewable energy that has been used for centuries is the use of energy from water currents in rivers and canals, transformed into mechanical energy.
- hydroelectric energy that is, the use of currents in waterfalls and their transformation into mechanical energy through turbines and in turn into electrical energy through alternators, is one of the main sources of renewable energy used in the present.
- this equipment in general, is fixed in a rigid position, so it can suffer or cause damage due to possible external impacts. In addition, they usually require a support structure from the sea or river bottom with a high environmental impact. In some, the device blocks the flow of water, not maintaining a passage for fauna and hindering the passage of ecological flows in the case of being used in rivers.
- the object of the present invention is to obtain an independent multiple hydrogenerator with a floating blade with a maximum thrust surface and self-orienting that generates electrical energy taking advantage of the sea and river currents regardless of their orientation and having little resistance to drift by the current.
- Another object of the present invention is to obtain an independent multiple hydro generator with a floating blade with a maximum thrust surface and self-orienting that can be fixed in a flexible way, thus reducing damage to external impacts, and has a reduced environmental impact as it does not need a support structure. from the seabed or from the river and by not blocking the current, maintaining a passage for fauna and an ecological flow in the case of applications in rivers.
- Another object of the present invention is to obtain an independent multiple hydro generator with a floating blade with a maximum thrust surface and self-orienting that allows its electrical connection, as well as its mechanical and electrical maintenance above the water surface, having several alternators that allow a major flexibility of use.
- the independent multiple self-orienting floating blade hydrogenerator with maximum thrust surface that is the object of the present invention is formed, at least, by a floating blade-shaped structure with four arms at each end of which there is an electric generator whose shaft is driven by the device defined in document ES1140760U Mechanism for converting the linear movement of a fluid into the rotational movement of an axis, which we will call from now on "conversion mechanism".
- each of the conversion mechanisms basically consists of a rotor with four arms fixed to a main rotation axis, at the ends of which it incorporates oscillating thrust pieces that act as blades.
- each of them is configured for an alternate clockwise or counterclockwise rotation direction. That is, if one turns clockwise, the next one will turn counterclockwise, the next one clockwise, and the last one counterclockwise.
- a tube is attached that is longer than the depth reached by the conversion mechanisms.
- This tube is partially closed at its lower end and has a chain or mooring cable attached to its central axis to the anchor or dead bottom.
- This tube has two openings for the input and output electrical cables.
- the tube has a fixed plate attached to it along the entire length of its generatrix and located in the intermediate position of the imaginary line that joins two adjacent conversion mechanisms in a clockwise direction around the axis of the blade.
- the forces acting on the fixed plate make the assembly rotate so that it always faces the entire cross section of the maximum thrust surface perpendicular to the direction of the water current, which enters through one of the sides of the imaginary square formed by the four conversion mechanisms.
- Each of the electric generators is accessible out of the water through a hatch through the upper part of the floating structure in the form of a cross.
- the cross-shaped floating structure has, in its center and outside the water, a dome that is also accessible through a hatch, inside which the connections, couplings and electrical treatment of the waves of electrical energy produced independently by each of the Electric generators.
- the electrical waves produced by the four independent generators can be electrically treated and coupled in series, in parallel or in a mixed configuration, depending on the speed of the water current at any given time (even at low speeds) for maximum use of energy.
- the device thus described presents the main advantages of the invention, as well as other additional ones, such as its lack of affectation to the seabed, its little visual impact and its simple construction, not requiring dams or civil works to channel water currents. .
- the device provides space for power electronics elements, transformers, etc., making it possible to connect to the distribution network well. in direct current with the maximum possible voltage and transformation on the ground, or alternatively in alternating current with transformation in each group and output with the highest possible voltage or mains voltage.
- Figure 1a shows an elevation view of a preferred embodiment of the self-orienting self-orienting multiple independent floating blade hydrogenerator object of the present invention.
- Figure 1b shows a top plan view of a preferred embodiment of the self-orienting multiple independent floating blade hydrogenerator with maximum thrust surface, object of the present invention.
- Figure 1c shows a bottom plan view of a preferred embodiment of the self-orienting self-orienting multiple independent floating blade hydrogenerator object of the present invention.
- Figure 1d shows a side view of a preferred embodiment of the self-orienting multiple independent floating blade hydrogenerator with maximum thrust surface, object of the present invention.
- Figure 2 shows a top perspective view of a preferred embodiment of the self-orienting multiple independent floating blade hydrogenerator with maximum thrust surface, object of the present invention.
- the self-orienting self-orienting multiple independent floating blade hydro-generator with maximum thrust surface is formed by at least one floating blade-shaped structure (1) with four arms at each end of which there is a electric generator (2) driven by a conversion mechanism (3) of the linear movement of a fluid in the rotational movement of an axis.
- each of them is configured for a clockwise or counterclockwise direction of rotation alternatively. That is, if one turns clockwise, the next one will turn counterclockwise, the next one clockwise, and the last one counterclockwise.
- a tube (5) longer than the depth reached by the conversion mechanisms (3) is attached to the central part of the blade-shaped structure (1).
- This tube (5) is partially closed at its lower end and has a mooring chain or cable attached to its central axis to the anchor or dead bottom.
- Said tube (5) has two openings for the input and output electrical cables.
- the tube (5) has a fixed plate (6) attached to it along the entire length of its generatrix and located in the intermediate position of the imaginary line that joins two mechanisms of conversion (3) adjacent in a clockwise direction around the axis of the blade (1).
- Each of the electric generators (2) is accessible out of the water through a hatch (7) in the immediately upper part of the floating structure in the form of a blade (1).
- the floating structure in the form of a cross (1) has in its center and outside the water a dome (4) also accessible through a hatch (8), inside which the connections, couplings and electrical treatment of the waves are made. of electrical energy produced independently by each of the electrical generators (2).
- the electrical waves produced by the four independent generators (2) can be treated electrically and coupled in series, in parallel or in a mixed configuration, depending on the speed of the water current at each moment (even with speeds low) for maximum use of energy.
