    Detailed description
    1a to 1c schematically illustrate a device 100 for recovering wave energy according to one embodiment. The device 100 is secured in place by a support structure 16, for example, to the bottom of a sea or other similar water basin or other fixed structure.
    The device 100 comprises a drum 1 rotatable about its central axis X-X. An electric generator 2 is arranged inside the drum 1 and arranged to be rotated by the rotational movement of said drum 1. In one embodiment, the device 100 comprises a gearbox 6 adapted to vary the speed of rotation and to direct the rotational motion of the drum 1 converted to a rotational motion rotating the electric generator 2. Alternatively, the drum 1 may be directly connected to an electric generator 2 without a gearbox.
    In one embodiment, the device 100 comprises a flywheel 7 adapted to be rotatable with an electric generator 2, which smooths and maintains the rotational movement.
    The device 100 further comprises a circumferential wheel 3 disposed at a distance from the drum 1 and fixedly rotatable with the drum on this central axis
    20185914 prh 31 -10- 2018
    X - X around. At least two blades 4 are disposed between the drum 1 and the peripheral wheel 3 to receive the movement of water. 1a to 1c has four blades 4. The number of blades may be less or greater.
    The wings 4 are arranged to pivot so that they can rotate from the first position to the second position. When the blade 4 is in its first position, the water movement in the first direction X1 of the drum center axis X-X tends to rotate, i.e. rotate the drum 1 in the first direction A. In one embodiment, the device 100 comprises a freewheel takes place in the second direction X2 of the central axis X-X of the drum 1, the blade 4 rotates to a second position where the blade 4 further tends to rotate the drum 1 in the first direction A, i.e. in the same direction as the water movement in the first direction X1. In other words, the electric generator 2 rotates in the same direction all the time, irrespective of changes in the direction of water movement.
    The direction of water movement and its change is detected by a pressure sensor 5 arranged to control the rotation of the blades 4. The pressure sensor 5 may comprise, for example, a magnetic flowmeter.
    In the embodiment shown in Figures 1a to 1c, the wing 4 is arranged to be pivotable as pivoted by two pivoting wheels 8.
    The pivoting wheel 8 is disposed parallel to and parallel to the circumferential wheel 3 and arranged to rotate about the central axis X-X of the drum 1. The speed of rotation of the pivoting wheel 8 is arranged to change from a lower speed of rotation of the peripheral wheel 3 to a speed of rotation of the peripheral wheel 3 and back.
    The pivoting wheel 8 is connected via a pivot arm 10 to the spool 11. The spool 11 can be said to be a rod-shaped shaft. The spool 11, in turn, is secured to the blade 4, so that the rotation of the spool 11 about its longitudinal axis also rotates the blade 4. The pivoting wheel 8 has suitably shaped fittings 17 which are conical openings in the direction of the circumferential wheel 3. Adapter 17 can of course be formed.
    The fitting 17 allows the pivot arm 10 to pivot with respect to the pivot wheel 8 and further with the pivot wheel 3 so that the pivot wheel 8 may have a different rotation speed than the pivot wheel 3. As the pivot arm 10 pivots as shown by the arrows
    20185914 prh 31 -10- 2018
    It should be noted that, in another embodiment, the device has only one swivel castor 8.
    Figure 2 is a side view of a device according to another embodiment. The device 100 'comprises four blades 4' disposed on the outer shell of the drum 1 'and substantially parallel to the central axis X' -X 'of the drum. The blade 4 'is arranged to pivot about the longitudinal axis of the spool 11' from the first position to the second position and vice versa. The circumferential wheel 3 'provides support for the sides 11' and rotates at the same speed as the drum T.
    The pivoting wheels 8 'are fitted to the ends of the blades 4' and, in the embodiment shown in Fig. 2, to the ends of the drum 1 '. It should be noted that at least one of the pivoting wheels 8 'is not mounted on the drum 1' but can rotate at a slower or faster speed than that of the drum T.
    The pivoting wheels 8 'are secured to the blades 4' by a pivoting arrangement 9 'which allows the angle of the blade 4' to change with respect to the pivoting wheel 8 'and also allows the blade head to move in the X' -X direction of the center axis of the drum.
    When the rotation speed of the first pivoting wheel 8 'is slowed down or accelerated relative to the peripheral wheel 3' and respectively the speed of the second pivoting wheel 8 'remains constant, or if the rotation speed of the second pivoting wheel 8' is reversed from the rotation speed of This allows the movement of the water to always rotate the drum in one and the same direction, regardless of the flow direction of the water.
    It should be noted that in another embodiment of this embodiment, the device has only one pivoting wheel 8 '.
    In the embodiment of Fig. 2, as in the embodiment of Figs. 1a-1c, rotation of the wing 4 'is arranged to be controlled by a pressure sensor 5'.
    Figure 3 shows some details of the device in side elevation and partially in section. According to one idea, the blade 4 is connected via a spool 11 to a conical gear 12 fitted inside the drum 1. The conical gears 12 of the different blades are connected by tooth contact. One of the blades 4 or the spokes 11 is further attached to a large conical gear 13 for rotation therewith.
    The large conical gear 13 is engageable and aligned perpendicularly to the axis X-X of the drum 1! with a conical gear wheel 14 arranged in relation to a large bevel gear 13. The speed of rotation of the pinion cone 14 is arranged to be reduced by the brake device
    20185914 prh 31 -10- 2018
    15. In turn, the brake device is already controlled by the pressure sensor 5 mentioned above. The embodiment shown in Fig. 3 has two adjusting conical gears 14 and a brake device 15.
    While the direction of the water flow movement remains unchanged, the adjusting pinion gears 14 do not rotate relative to the large pinion pinion 13. When the pressure sensor 5 detects that the water flow direction is changing, it directs the second brake device 15 to brake, or even stop, the speed of rotation of the respective pinion gear 14. As a result, the large bevel gear 13 rotates with respect to said adjusting bevel gear 14, whereby the spindle 11 and the wing 4 attached to the large bevel gear 13 rotate respectively, and the same spin movement is transmitted through the bevel gears 12 to
    In a simpler embodiment, there is only one adjusting cone gear 14 and one brake device.
    Fig. 4 is a perspective view of a device according to a third embodiment and partially cut away. This comprises a straight surface drum 1 "with four blades 4" fitted on the outside. It should be noted that the straight surface drum 1 'can also be used in the above embodiments of the device, and vice versa: the circular cylindrical drum can be used in the embodiment of Figure 4. Further, it should be noted that the number of blades 4 "may be greater than four - whatever the shape of the drum - and may be arranged in series, parallel and / or overlapping the outer surface of the drum.
    Wings 4 "is pivotably arranged in the direction of arrow Y 'in the manner according to the water flow direction stoppers 18' between so that the drum 1 'rotates in a first rotational direction" regardless of the direction of flow.
    According to one idea, the device 100 'comprises a gear arrangement shown in Figure 3 which rotates the blades as the water flow changes.
    A guide tube 19 "is provided around the drum 1" which directs and enhances the flow of water relative to the wings 4 ". Further, the device 100 "comprises a guide cone 20" which guides the water to the blades 4 ". It should be noted that the guide tube 19 "and the guide cone 20" may also be used in conjunction with the other embodiments disclosed herein.
    20185914 prh 31 -10- 2018
    Fig. 5 is a perspective view and partially sectional view of a device 100 "according to a fourth embodiment. The device shown in Figure 5 is intended to be placed at the bottom of the sea, where even a strong, reversible flow of water can occur. The device can be installed on both sloping and horizontal seabed. Water can flow from each end into the body laitteen of the device and toward the blades 4 '' so that water flows into the device 100 'only from the end facing the water flow. The device 100 '' functions as a continuously rotating actuator, irrespective of the point at which water flows into the device. The device 100 '' comprises a body part 24 '' on which the drum Γ 'of the device, the electric generator 2' 'and the blades 4' '(which are rotatable as in other embodiments of the invention) and preferably the gearbox 6' 'of the device are secured. Attempts have been made to illustrate the rotation of the wings by drawing the wings 4 '' in addition to the dotted line. The body part 24 '' is attached to the support structure of the device 16 " 'and arranged to be rotatable relative to the support structure so that it can rotate back and forth on the support structure of the vertical axis Y' '- Y' 'round the double arrow B' 'in accordance with. When the device comprises, as shown in Fig. 5, two guide tubes 19 '' pointing in opposite directions, the maximum angle of rotation may preferably be, for example, 80-100 sets, which in practice allows sufficient turning of the device to meet practical needs. The drum Γ "of the device and the blades 4 '" and preferably also the gearbox 6 "" of the device and the electric generator 2' "are arranged to be tilted relative to the support structure 16 '" on the horizontal axis X3 "- X3". The double arrow C "'illustrates the tilt of the device. The horizontal axis X3 "-X3 '" is attached to the body ring 21' "which surrounds the drum Γ". It is contemplated that the housing ring 21 '' is used instead of a kind suitable second body member, which allows the device body Γ "tilting of the double arrow C '' to illustrate the directions.
    The structure described above allows the drum Γ "and the blades 4 '" to rotate in three directions relative to the support structure 16' "so that the device can always be turned against the flow of water for the best power to the generator 2 of the device.
    The embodiment of Figure 5, like the third embodiment of the invention, further comprises a guide tube 19 '", a guide cone 20'" (at each opposite end of the device) and, as with all embodiments of the device, one or more pressure sensors 5 '". The guide cones 20 '' are connected to the guide tube 19 '' by support plates 22 '' or the like. In addition, it is recommended to have the device
    20185914 prh 31 -10-2018 gearbox 6 "" and flywheel 7 "" rotatable with electric generator 2 "". Wings 4 'are preferably associated with stops (not shown). Reference numeral 23 "" indicates a gas reservoir at the top of the device 100 '', preferably containing air. The gas reservoir 23 '' exerts an upward lifting force on the device 100 '' which tends to adjust the position of the device so that its central drum T "center X" "-X" "is horizontal.
    As shown in Fig. 6a, the spindle spool 11b of the device may have a gear rack assembly 25b at the peripheral wheel 3b comprising a gear and a rack for changing the position (angle) of the wing. The position of the blade changes through the rack and pinion as the water forces push the pivoting wheels 8b relative to the peripheral wheel 3b. The double arrow D illustrates the displacement of the pivoting wheels 8b with respect to the peripheral wheel 3b and the bobbin 11b of the wing 4b which rests thereon. Figures 6a and 6c illustrate that at the end of the blade spindle 11b, the outer periphery may have a remotely controlled brake device 15b for controlling the blade 4b at various angles of rotation and also for releasing the blade. The spool 11b of each wing 4b has such a braking device 15b. The pressure sensor 5b reacts to the magnitude of the water flow. The signal from the pressure sensor 5b is utilized to command the brake device 15b to release and lock the blade 4b so that the operation of the device responds to changes in water flow. Said operation is preferably computer controlled to optimize the operation of the device so as to recover as much energy as possible from the water flow. 6b, the pivoting wheels 8b are bonded to one another. Preferably, the engaging member may be an axis which prevents the pivoting wheels 8b from causing friction to the peripheral wheel 3b as the pivoting wheels move. The notation B-B in Fig. 6b illustrates where, by looking at Fig. 6b, a view similar to Fig. 6a is displayed. Double arrow E illustrates rotation (rotation) of wing 4b. The device of Figures 6a-6c is preferably associated with the guide tube of Figure 5 (cf. the guide tube 19 '' in Figure 5; not shown in Figures 6a-6c). As with other embodiments of the invention, the rotor (not shown in Figures 6a-6c) rotates in only one direction, indicated by arrow A in Figures 6b and 6c.
    It will be obvious to one skilled in the art that as technology advances, the basic idea of the invention can be implemented in many different ways. In some cases, the features set forth in this application may be used as such, despite other features. On the other hand, the features disclosed in this application may be combined, if necessary, to form various combinations. The inventions, therefore, are not limited to the examples described above for purposes of illustration, but may vary within the scope of the claims.
