Description

AN ENERGY GENERATOR EXPLOITING TIDAL/WAVE MOVEMENTS
This invention concerns an energy generator that exploits sea waves and currents, and having improved functioning and a higher yield, compared to similar mechanisms of the prior art.
In the history of energy technology, attempts have been made a number of times to convert the movement of masses of sea water into a renewable and clean source of energy. Over the course of several years and using various modes of construction, different types of generator apparatuses have been designed. In general, they are submersed in an area of the sea and are subjected to the pressure of the waves or currents, thus converting this movement into kinetic energy suitable for moving an electric generator.
There are various problems with the prior-art systems, among which low yields (caused for example by the very chaotic type of movement of the waves), high management costs and conditions of intensive wear and corrosion (caused by seawater).
In order to solve the problems of the prior art, this invention is thus aimed at realizing an energy generator exploiting tidal wave movements that is more economical and offers a markedly greater energy yield, high reliability in terms of the structure and high levels of resistance to wear and corrosion.
These aims are achieved by an energy generator exploiting tidal wave movements according to that which is disclosed and claimed herein, and illustrated below in detail regarding a possible embodiment thereof, in addition to being illustrated in the following figures, where:
- Figure 1 is an overall view of a generator according to the invention, in a first operative stage thereof;
- Figure 2 is an overall view of the generator of Figure 1 in a second operative stage thereof; and
- Figure 3 is a hydraulic or pneumatic system diagram of the operative sub-assemblies included in the generator of Figures 1 and 2.
The generator is indicated in its entirety by the reference number 1 in the figures illustrating the present invention. The generator basically comprises wave energy capturing body (2), which is submerged in a moving mass of water and is thus suitable for moving in wave fronts and/or currents hitting or impacting the capturing body (2); an energy conversion assembly (3) is connected to the capturing body (2) and it is, in turn, interlocked with a generating unit (4) (e.g. a common electric generator). The invention is principally characterized by the presence of a spacer connection (5) positioned between the capturing body (2) and the energy conversion assembly (3): the spacer connection (5) enables the capturing body (2) to remain exposed constantly to the wave fronts and/or current, while at the same time also enabling the energy conversion assembly (3) to remain positioned above the level of the free surface of the mass of water (therefore remaining exposed as little as possible to the erosive action of the water, which acts only upon the capturing body).
As mentioned previously, the energy conversion assembly (3) comprises a power generating set (6) and it is thus capable of converting multidirectional movements of the capturing collector (2) (which correspond to the multi-directional movements that can be taken on by the tides and waves or by the course of a current within the mass of water) into movement of the generating set (6) in one direction.
It can be noted from the figures attached herein that the spacer connection (5) is realized by means of an elongate bar-shaped body and it can also be observed that the energy conversion assembly (3) comprises:
- a connection sub-assembly (3a) that receives movements of the spacer connection (5);
- a kinematic conversion sub-assembly (3b) that is connected to the connection sub-assembly (3a) and converts the movements of the spacer connection (5) into back-and-forth linear motion of at least one pushing body (7); and - a hydraulic or pneumatic conversion sub-assembly (3c) that selectively and alternately exploits the back-and-forth linear motion of the pushing body (7) so as to impose movement in a sole direction upon the generating set (6).
In order to explain in further detail the overall structure described above, note that the connection sub-assembly (3a) comprises a support base (8) that is spaced away from the level of the free surface of the mass of water and in fact, it bears and supports all the components of the conversion assembly (3), which, in particular bears and supports a fulcrum pin (9) connected to the support base (8). This fulcrum pin (9) enables the spacer connection (5) to execute pendular movements.
Naturally, within the scope of this invention, other possible movements and geometric structuring of the spacer connection are possible (e.g. linear translational movements or rotations of bladed bodies). In these alternative cases, the fulcrum pin can be replaced with an equivalent kinematic structure without departing from the scope of the patent.
As regards the details of the kinematic conversion sub-assembly (3b), it comprises one or (as shown in the figures) two countershafts (10) connected to the fulcrum pin (9) and to the support base (8) so as to develop the necessary back-and-forth linear motion. These back-and-forth movements are exploited by the hydraulic or pneumatic conversion subassembly (3c), which for this purpose comprises one or two pistons (1 1 ) (which can be single- or double-acting pistons, for example if one wishes to exploit the movements of particularly strong waves or currents), connected to the respective countershafts (10).
The pistons (1 1 ) are, in turn, connected to one or two hydraulic circuits (12) exiting from the respective pistons (1 1 ). These hydraulic circuits converge towards a flow rectifying valve (13) connected to the hydraulic circuits (12) and that serves to operate selectively and alternately on the flows (of working fluids: liquid or gaseous) coming from the hydraulic circuits (12). The alternated selection of the flows indicated above is used by the rectifying valve (13), to generate an overall unidirectional flow towards the generating set (6) so as to actuate the movement thereof in a sole direction. For example, if the generating set is constituted by a rotor and a stator, a rotating movement of the rotor in one direction is actuated.
Given that wave motion and currents are generally highly subject to changes over time, the generator 1 can advantageously be equipped with an additional functional sub-assembly. This sub-assembly can be defined as a hydraulic or pneumatic conversion sub-assembly (3c) and it is essentially based on an accumulator (14) connected to the hydraulic circuits (12) and to the flow rectifying valve (13) so as to enable the buffering of peaks and drops in hydraulic or pneumatic pressure.
To comprehend the function of the accumulator (14) better, it can be said that it ensures parameter constancy concerning the movement of the generating set (6) in one direction. Moreover, the detailed structure of the accumulator (14) is clearer in Figure 3, where it can be noted that it is constituted by a reservoir that holds an amount of working fluid, which can, in turn, be put into a state of interaction by an overlying compensating mass of gas/air. The fluctuations in the pressure of the working fluid in the circuits (12) are thus compensated for by the spontaneous pressurization/depressurization of this reservoir.
In the overall view of Figure 3, other structural details are observable, such as:
- the possible bidirectional courses of the flows of working fluid in the circuits (12) departing from the two opposite half chambers of the pistons
(1 1 ) towards the rectifying valve (13);
- the unidirectional flow exiting from the rectifying valve (13) and moving towards the generator (6) (or in further detail, towards the turbine (6a) that is part of the generator and connected to a speed reducer (6b) set at the entrance to the rotor (6c) of the actual generator); and
- the distributor valve (15), which is hydraulically or pneumatically positioned between the accumulator (14) and the hydraulic or pneumatic circuits (12), and at the same time, it is also connected to the turbine (6a) at least on the discharge line thereof.
Again, with extreme variability being taken into account, not only in terms of force, but also in terms of direction and conditions, for example the varying ocean bottom depth or varying tide levels, this innovative generator is also characterized by the presence of regulating means for regulating the height of the support base (9) and/or of the spacer connection (5) with respect to the level of the free surface of the mass of water. This means raises and lowers the "working part" of the generator so as to maintain optimal exposure of the capturing collector (2) to the waves or currents at all times, while also keeping the energy conversion assembly (3) protected from adverse environmental conditions related to the mass of water.
Owing to efficiency-related issues and maximum exploitation of the energy of the waves or currents, orienting means for orienting the capturing collector (2) and/or for orienting the energy conversion assembly (3), with respect to a prevalent direction of wave movement or a current within the mass of water, can also be present, as is observable in the two possible orientations schematized in the figures. Obviously, thanks to the electronic technology available today, all the adjustments in height or "direction" described above can be determined using automatic (and electronic) control means. The control means thus automatically regulates the height with respect to the level of the free surface of the water and/or the orientation with respect to the prevalent direction of wave movements or a current and therefore the control means can be integrated in or added to the capturing collector height regulating means and/or orientating means. The invention solves the problems of the prior art, above all in the sense of improving yield and resistance to wear and corrosion.
In fact, the minimal part of the generator that remains in actual prolonged contact with seawater, reduces to very low levels the probability of excessive mechanical stress affecting the structure, and at the same time exposes only a very limited portion of the structure to the moist, saline environment.
As a result, the positioning of the entire part for converting kinetic wave energy above the surface of the sea is in any case linked to the possibility of rapidly and simply repositioning, and re-orienting the entire generator unit according to the optimal flow of the tidal waves or according to the best possible aligned direction of an exploitable current.
It should also be noted that the possibility of repositioning the generator with different orientations with respect to the wave fronts or with respect to different current depths makes the entire invention extremely adaptable to different marine environments (bays, areas of open sea and so on).
Lastly, it should be observed that the extremely compact design in terms of overall dimensions and above all in terms of vertical extension above the surface of the sea makes it possible to integrate and conceal this generator also in coastal engineering works such as breakwaters, wharfs or piers, which could thereby exploit tidal wave movement and even waves artificially generated by passing watercrafts.
