If needed, also the open end of the hydraulic cylinder 7 a is water tightly closed with the closing and sealing mechanism 12, and the power transmission mechanism 6 d, 9, such as the piston 9 is locked inside the hydraulic cylinder 7 a, for instance by the hydraulic pressure of the hydraulic circuit 9 b of the PTO unit 7. After that the PTO unit 7 is separated from the pedestals 7 b and lifted up to the surface of the water. The closing and sealing mechanism 12 comprises for instance two gate valves that are installed into the opening of both the cylinders 6 b and 7 a. The energy transfer arrangement according to the invention is suited very well for instance to be used in connection with a panel or flap or essentially plate-like wing element, later called shorter only as panels, hinged with its lower edge to make a reciprocating movement caused by wave energy or tidal energy of seawater.

The actuating mechanism 6 having a rectilinear actuating rod 6 a is fastened through the lever mechanism 8 to the lower part of the panel 2 and arranged to make reciprocating linear motion together with the panel 2. The linear motion of the actuating rod 6 a has been arranged to push linearly the power transmission mechanism 6 d of the PTO unit 7, which power transmission mechanism in this embodiment is a pinion rack. The pivot shaft 4 is inserted through the central hole and the toothed outer side is connected in the gap 2 a with a corresponding coupling element on the inner end surface of the panel 2. Thus, the coupling elements 8 a make a reciprocating rotary motion along with the panel 2 about the pivot shaft 4, and at the same time the levers 8 b and 8 c force the actuating rod 6 a to move rectilinearly back and forth guided by cylinders 6 b.

Each coupling element 8 a is coupled in the gap 2 a to a corresponding circular toothed coupling element 2 b that has been fastened onto the inner end surface of each half of the panel 2 so that the coupling element 2 b makes a reciprocating rotary motion along with the panel 2 about the pivot shaft 4 that is inserted through the central hole of the toothed coupling elements 2 b and 8 a. In the arrangement according to the invention the reciprocating motion of the panel 2 is transferred mechanically to a linear motion of the power transmission mechanism 6 d, 9 of each PTO unit 7 through the mechanical intermediate mechanism between the panel 2 and the PTO units 7. In that case the reciprocating motion of the panel 2 is transferred first to the lever mechanism 8 and through the lever mechanism 8 to the actuating rod 6 a that is guided to make a reciprocating linear motion in the rate of the reciprocating motion of the panel 2. When the capture of the wave energy is activated the actuating rod 6 a is arranged to push the power transmission mechanism 6 d, 9 of each PTO unit 7 in turns in order to produce a linear thrust motion for converting the wave energy to another type of energy.

FIG. 6 presents the situation where the hydraulic cylinder 7 a of the PTO unit 7 has been separated from the guiding cylinder 6 b and the PTO unit 7 is ready to be lifted to the surface of the water. Dolor de brazo derecho y espalda . Before the removal the first end 9 e of the piston 9 is taken away from the guiding cylinder 6 b and the piston 9 is pressed towards the closed end of the cylinder 7 a by a pressure of the hydraulic circuit 9 b of the hydraulic PTO unit 7 through a connector 10 b from where the hydraulic fluid runs to a hollow cylindrical space 11 between the inner surface of the cylinder 7 a and the outer surface of the first section of the piston 9 which first section of the piston 9 is smaller in its diameter than the second section of the piston 9 closer to the closed end of the cylinder 7 a.

The most of the hydraulic fluid in the space 9 a has been pressed to the hydraulic circuit 9 b of the hydraulic PTO unit 7 through a connector 10 a, and the first end 9 e of the piston 9 is still inside the guiding cylinder 6 b strongly in touch with the second pusher end 6 f of the actuating rod 6 a. Each pusher end 6 e, 6 f of the actuating rod 6 a is closed into a guiding cylinder 13 that is fastened to the base 1 through support pedestals 13 a. Both the ends 6 e, 6 f of the actuating rod 6 a are arranged to slide guided back and forth inside the guiding cylinders 6 b.

When the hydraulic cylinder 7 a is in function the first end 9 e of the piston 9 is always inside the guiding cylinder 6 b. In that case the part of the power transmission mechanism 6 d, 9 that is inside the guiding cylinder 6 b, 13 is at first moved out from the guiding cylinder 6 b, 13 of the actuating rod 6 a and after that the closing and sealing mechanism 12 for closing the open end of the guiding cylinder 6 b, 13 is activated and the open end of the guiding cylinder 6 b, 13 is water tightly closed. In this way the piston 9 can be locked in its entirety inside the cylinder 7 a, and after that the cylinder 7 a can be easily and safely separated from the guiding cylinder 6 b.

5 the actuating rod 6 a is at its utmost position to push the piston 9 inside the hydraulic cylinder 7 a towards the closed end of the cylinder 7 a. The pusher ends 6 e, 6 f are arranged to push the power transmission mechanism 6 d of the PTO units 7 in turns so that when the first pusher end 6 e is pushing the pinion rack 6 d of the first PTO unit 7 the second pusher end 6 f is returning from pushing the pinion rack 6 d of the second PTO unit 7, and the pinion rack 6 d of the second PTO unit 7 follows the second pusher end 6 f rotating at the same time the gear wheels 14 of the PTO unit 7, which gear wheels are disconnected from rotating the generators 15 for instance by a freewheel clutch.

Each gate valve comprises for instance a manual or electric actuator 12 a and a gate 12 b that is moved by the actuator 12 a either to close the openings of the cylinders 6 b and 7 a when the hydraulic cylinder 7 a has to be removed, or to open the openings of the cylinders 6 b and 7 a for activating the wave energy recovery arrangement. The driving and PTO arrangement 5 comprises the actuating mechanism 6 and one or more electric PTO units 7, in this example there are two PTO units 7 that are mutually similar and placed opposite to each other in the different sides of the panel 2 in the direction of the reciprocating motion of the panel 2. In addition to the lever mechanism 8 the actuating mechanism 6 comprises the rectilinear actuating rod 6 a, which can be for instance a steel pipe with a strong wall.

By this way the actuating mechanism 6 is arranged to transfer the reciprocating motion of the panel 2 mechanically to the linear motion of the piston 9 of the hydraulic power-take-off units 7 of this example embodiment. The actuating mechanism 6 is arranged to transfer the reciprocating motion of the panel 2 mechanically to a linear motion that rotates the generators of the PTO units 7. The structure and functions of the wave energy recovery apparatus according to this embodiment of the invention are basically the same as described above in connection with the example embodiment of FIGS. According to prior art there are various types of wave energy recovery systems where the arrangements include a base and, for instance, one or more panels pivotally connected to the base to make a reciprocating or oscillating movement about a rotation axis or pivot axis in response to wave forces or tidal forces.
