Definitions
- the invention relates to the field of energy recovery and more particularly the energy of the sea swell.
- wave energy is never anything but a particular form of sola ire energy.
- the sun heats unevenly the different atmospheric layers which causes air currents (winds) themselves responsible by friction of the movements that animate the surface of the sea (currents, waves, waves).
- the waves created by the wind on the surface of the seas and oceans carry energy. When they arrive on a floating or coastal obstacle, they can give up some of this energy, which can be transformed into electric current. This is where the winds are the strongest, between 40 ° and 60 ° of latitude, that the power of the waves is maximum.
- the wave energy has a very high power potential.
- the average power transported by the waves is given in kW per linear meter. It is proportional to the wave period (the time between the arrival of two successive wave peaks) and the square of the height of the wave (distance between the trough and the ridge).
- this potential is 63 kW / m off Ushant, 50 kW / m on the Atlantic coast and 8 kW / m in the Mediterranean.
- document EP 1 295 031 discloses a device based on the movement of a buoy, the device comprising an outer round float surrounding an inner float, these two floats being connected to one another by means of l yaison including hydraulic cylinders allowing the recovery of energy movement between the two floats and further having a body immersed.
- a mobile cyl lash (the float) filled with air that slides on a cylinder attached to the bottom of the sea.
- the float In the absence of wave the float is in equ ilibre. When the top of the wave passes over the float the overpressure depresses the float. In the hollow of the wave the depression makes the float rise. The comings and goings of the float relative to the fixed cylinder causes a linear dynamo producing electric current.
- This device however has the disadvantage of having to be fixed in part at the bottom of the sea. [0009]

- the at least one mobile float is connected to the structural element by at least one rigid arm rotatably mounted about an axis of the structural element substantially parallel to the surface of the sea, and said energy generating means is directly or indirectly linked to said rigid arm.
- the energy generating means comprises a linear generator having a piston connected to at least one of said mobile floats, and that i coul isse in a cyl rim l ied to the structural element.
- the energy generating means comprises at least one pump having a cylinder and a rod, one end of which is articulated on a rigid arm of at least one of the mobile floats, and of which the other end is related to the structural element.

- the shortest arm or arms will be arranged "at the exit" of the waves, that is to say close to an extremity the device placed opposite the end that receives directly (front) waves.
- at least one structural float is fixed relative to the structural element, disposed at the level of flotation so that the structural element is mainly disposed above the sea surface.
- At least one of said articulated structural floats is disposed at one end of an oscillating arm l ié to the structural element by at least one prem articulation, said arm having at its extremity a second articulation associated with the rod of a piston of a jack fixed on the structural element above the floatation level, said piston being intended to actuate said means of energy generation.
- At least one of said articulated structural floats is traversed by an oscillating arm connected to the structural element by two joints the first disposed below the floatation level consists in a pivot connection, the second link comprises a joint associated with the rod of a piston of a jack fixed on the element structural structure above the floatation level, said piston being adapted to actuate said energy generating means.

- Fig. 15 is an enlarged view of the connection between a structural float and the structural member of the fifth embodiment of the invention.
- the invention comprises a rigid structural element 1 as a whole, which floats at sea level 0 with at least one buoy or so-called structural float 2.
- the element structural may consist of beams that extend substantially parallel to the waves, and beams perpendicular to them; many solutions are possible; assuming that the swell is oriented along the arrow H, a spacing between two structural floats 2 2 'of the order of a wavelength of wave will preferably be chosen, as illustrated in FIG. This is a known arrangement that can best recover the energy of the swell.
- 2 is a forward float, while 2 'is a back float; the terms "forward” and “rear” refer to the direction of wave propagation of the swell.
- At least one float 3, 3 ' is provided, movable with respect to the structural element 1.
- the float or float 3 cooperates with an energy generating means 4 which can be in various forms. In any case, the energy generating means 4 is fixed on the structural element 1.
- the mobile float 3 is connected to the structural element 1 by at least one rigid arm 5 mounted rotatably about an axis 50 substantially parallel to the surface of the sea.
- the mobile float or 3 are connected reliably to the structural element 1 and their relative movement vis-à-vis the structural element 1 is fully integrated.
- the rigid arm (s) 5 guide and hold the movable floats 3 opposite the structural element.
- arm is meant any type of support means such as one or more rods, an apron, chains ...
- each float 3 is connected directly or indirectly to a means 4 of energy generation; more specifically according to Figure 1 the float 3 is connected to the cylinder 7 of a pump which comprises a rod 6 of a piston which slides in said cylinder 7 fixed on the structure and serves as a means of energy generation. Indeed, under the effect of wave movement, the piston slides in the cylinder and compresses or relaxes the fluid present inside the closed chamber of the pump.
- the energy of the swell can be transmitted by pistons, cylinders, linear generators or any other technically equivalent means.
- a spacing between two structural floats 2, 2 'substantially equal to an average wave wave length is chosen, and it is positioned the means 4 substantially in the middle of said length so that when the floats 2, 2 'are for example in wave recesses (solid line in Figure 1), the means 4 is at a wave crest so that the water level in the closed chamber of the pump is at a maximum, which i generates the reduction of the vol ume A and thus the compression of the fluid (air) present inside. This compression induces a recoverable energy.
- the structural float 3 is in the hollow of a wave (in dashed lines in FIG.
- the level of the water drops down and the rod 6, so that the pressure of the fluid in the chamber Decreases.
- the wavelength of the waves is generally a known and characteristic value of a given place. The dimensioning of the device according to the invention will advantageously take account of this parameter.
- FIG. 1 schematically shows the additional mobile float 3 'connected by an additional rigid arm 5' articulated on the element structural 1.
- the rigid arm 5 ' is mounted as the first rigid arm 5 that is to say rotating about an axis substantially parallel to the surface of the sea, the hinge point 50' on the structural element 1 being here chosen at the opposite end of the hinge point 50 relative to the direction of propagation of the swell (arrow H).
- An additional means 4 'of energy recovery is coupled to the float 3', here via the rigid arm 5 '.
- the movement of the additional float 3 ' is thus used by the energy recovery means 4', in the same way as explained above with respect to the mobile float 3.
- the distance between the two floats 3, 3 ' makes it possible to recover from the energy induced by the additional float 3 'when the float 3 is for example at top dead center or bottom dead center, that is to say when it produces no energy.
- any suitable structure may be provided on the structural element 1 to support the additional means 3 ', 4', 5 'which have just been described.
- the rigid arms 5, 5 'of connection and support between a float 3, 3' and the structural element 1 preferably have different lengths; it will be possible advantageously to choose a longer length for the arm 5 disposed as close as possible to the inlet of the swell on the device, and a shorter length for the arm 5 'situated at the outlet of the device.
- Entrance means the area of the device that is affected by the swell before any other area.
- Exit is the area at the other end of the structure relative to the direction of wave propagation.
- the arm 5 and the associated float 3, arranged at the entrance of the device, are subject to the most important efforts; while the arms 5 'and additional floats 3' are subjected to less effort because the energy of the wave has been attenuated between these two points.
- FIG. 2 illustrates an embodiment of the invention which differs from that of FIG. 1 essentially by means of energy generation which here comprises a hydraulic pump 14 associated with an accumulator 15 and with a hydraulic motor 16 with a generator.
- a hydraulic pump 14 associated with an accumulator 15 and with a hydraulic motor 16 with a generator.
- the skilled person will choose according to needs, costs, desired performance, etc.. one embodiment or the other.
- At least one buoy 2 or structural float is provided, fixed vis-à-vis the structural element 1 and disposed at the floating level. Any means known per se can be provided to achieve this float function which therefore will not be further detailed.
- the structural float or floats 2, 2 'thus maintain the structure 1 at a given level vis-à-vis the level of flotation; moreover they are subject to the efforts generated by the waves.
- FIG. 3 illustrates an improved mode of realisation of the invention.
- the improvement consists in particular in providing at least one structural float 2 articulated vis-à-vis the structural element 1 (or frame).
- the structural element 1 is partially immersed as shown in this figure.
- At least one of the structural floats 2 is connected by an oscillating arm 8 connected to the structural element 1 via at least a first hinge 81 disposed above the buoyancy level 0.
- the float 2 in him -Even can be placed substantially at the end of the oscillating arm 8, and there is provided a first hinged connection 81 which cooperates with a second articulated end 83 itself connected to a cylinder 84, or more precisely with the rod 82 of the cylinder 84 attached to the structural element 1.
- the or each arm 8 oscillates around the hinge 81 in a plane substantially perpendicular to the surface of the sea.
- the end 83 of the arm 8 opposite to that carrying the float 2 provides a movement back and forth at cylinder 84 or to any other element of recovery of energy, which is therefore added to the energy created by the movement of the float or mobile floats 3, 3 ".
- the cylinder 84 associated with the movement of the arm 8 allows energy production, for example via a battery 15 or any other equivalent means such as an electric generator for example fixed on the structure, not far from the cylinder or cylinders 84 .
- this embodiment is interesting because the energy provided by the movement of the structural floats 2, 2 'is added to that provided by the movement of the float or floats 3, 3'.
- several oscillating floats 2 can be mounted on the structure 1 which itself may have several variants.
- Figure 3 shows two floats (or set of floats) structural 2, 2 'but of course this is only a non-limiting example.
- Figures 4A and 4B illustrate an embodiment according to which the structure (or structural element) 1 consists of a frame substantially disposed in a plane.
- the means of the invention such as the structural float (s) 2, 2 ', the mobile float (s) 3, 3' and the associated arms 8, 8 ', 5, 5' as well as the joints and cylinders are here borne by such a framework.
- the skilled person will select and size the support elements and others according to his general knowledge.
- FIG. 4A which is a simplified sectional view along AA of FIG. 3, shows a cylindrical mobile float 3 'disposed at the end of a double arm 5' articulated on the structure 1.
