Another object of the present invention is to make the installation, maintenance and repairs of the wave energy conversion apparatus easy and fast, and to make it possible to easily disconnect/connect the PTO arrangements from/to the other structure as one package without disturbing the functions of the other structure. The wave energy or tidal energy collected is further converted underwater with a conversion unit for instance to electric energy. 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 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 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.

For instance the hydraulic cylinders of the PTO units can be used to convert the captured wave energy to pressurized seawater with a pressure between approximately 1-300 bar. The damping element 20 is for instance a spring that can be adjusted according to need. In that case the connecting rod 4 b that is partially inside the guiding cylinder 6 b is at first moved out from the guiding cylinder 6 b 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 is activated and the open end of the guiding cylinder 6 b is water tightly closed. FIG. 6 presents in an enlarged side view, cross-sectioned, and in a simplified and diagrammatic way the second end of the driving and PTO arrangement 5 of the wave energy recovery apparatus according to the invention in the second position where the panel 2 has moved to its opposite position and the first end of the actuating rod 6 a is pushing the pistons 9 inside the second hydraulic cylinder block 7 a towards the closed end of the cylinders 7 h.

A cylindrical extension 9 d is fastened in the center of the first side of the connecting plate 9 c facing towards the actuating rod 6 a when the PTO unit 7 is installed in its working place. Before the removal the first end 4 d of the connecting rod 4 b is taken away from the guiding cylinder 6 b and the pistons 9 are pressed towards the closed end of the cylinders 7 h by a pressure of the hydraulic circuit 9 b of the hydraulic PTO unit 7 for instance through connectors 10 b from where the hydraulic fluid runs to a hollow cylindrical space 11 between the inner surface of the cylinders 7 h and the outer surface of the first section of the pistons 9 which first section of the pistons 9 is smaller in its diameter than the second section of the pistons 9 closer to the closed end of the cylinders 7 h.

The transmission mechanism of each PTO unit 7 comprises at least the pistons 9, the connecting plate 9 c with its extension 9 d, and the connecting rod 4 b that is a separate element in this example but can also be combined with the connecting plate 9 c being a statutory part of the connecting plate 9 c. Also the maintenance and/or repairs of the driving and PTO assemblies according to prior art can be time consuming, expensive and even dangerous. Each dual-action cylinder 7 h comprises two piston heads 9 g, 9 s of a different size, and therefore the pairs have two modes of action, as described above. A group of two-piston cylinders like this can be assembled in the same kind of a cylinder block 7 a as is mentioned above.

The maintenance and repairs problem mentioned above has been tried to solve by a solution shown in the international patent publication No. 23, 2015, as International Publication WO2015/193532, the content of which is incorporated herein by reference in its entirety. On the base 1 there are advantageously two or possibly more supporting legs 3 that are fastened onto the base 1 so that at least one supporting leg 3 is situated at each side of the panel 2. At its upper end each supporting leg 3 supports an essentially horizontal, back and forth rotating pivot shaft 3 a on which the two halves of the panel 2 are mounted at their lower edges so that the panel 2 can make a reciprocating motion along the movement of the seawater, for instance along the movement of waves. Dolor lumbar por escoliosis . The cylinders 7 h or pair of cylinders 7 h can be deactivated and activated one by one depending on weather conditions or when a cylinder or a pair of cylinders need maintenance or repair.
The job is slow, difficult and expensive, and can also be dangerous. 14. Then there are for instance a pair of the smallest two-piston cylinders, a pair of the second smallest two-piston cylinders and a pair of the largest two-piston cylinders. 5 the actuating rod 6 a is at its utmost position to push the pistons 9 inside the second hydraulic cylinder block 7 a towards the closed end of the cylinders 7 h. Then the first end of the connecting rod 4 b is inside its own guiding cylinder 4 a, and the panel 2 and the actuating rod 6 a may make their reciprocating motion freely without the risk that the structures of the wave recovery apparatus would suffer damages. The driving and PTO arrangement 5 is protected with a sealed protection cover 5 a against seawater.
At the same time the second end of the actuating rod 6 a has retracted to its innermost position inside the guiding cylinder 6 b, and the connecting rod 4 b and the connecting plate 9 c with the piston rods 9 e have followed the actuating rod 6 a so that the whole package comprising the actuating rod 6 a, the connecting rod 4 b and the connecting plate 9 c with its extension 9 d and piston rods 9 e has kept tightly together. The length should be equal to the sum of the length of the connecting rod 4 b and the extension 9 d of the connecting plate 9 c in the present embodiment. The arrangement comprises also a locking mechanism that locks the second end of the connecting rod 4 b to the extension 9 d so that when the pistons 9 are run into their locking positions inside the cylinders 7 h the extension 9 d draws the connecting rod 4 b with so that the connecting rod 4 b keeps tightly in touch with the extension 9 d. FIG.

So, the solution has three different sizes of hydraulic cylinders 7 h in pairs. Yet more control flexibility is achieved when two-piston cylinders are in pairs of different sizes as is described in connection with FIG. And finally, the column headed “Dual-acting cylinder pairs of a different size” gives the control variations when using three pairs of dual-acting cylinders but now the pairs comprise cylinders 7 h of a different size so that the first pair includes two smallest dual-action cylinders 7 h that are mutually equal, the second pair includes two second smallest dual-action cylinders 7 h that are mutually equal, and the third pair includes two largest dual-action cylinders 7 h that are mutually equal. Que ejercicio es bueno para el dolor de espalda . The column headed “Equal-sized dual-acting cylinder pairs” gives the control variations when using three pairs of cylinders but now the pairs comprise dual-action cylinders 7 h of the same size. During the working phase the closing and sealing parts make reciprocating motion inside the cylinders 6 b and 4 a closed to each other between the pusher ends 6 e, 6 f of the actuating rod 6 a and the first end of the connecting rods 4 b.
In this example the number is six and all the six hydraulic cylinders 7 h are placed symmetrically next to each other and/or one upon the other. The connecting rod 4 b and the piston rods 9 e are making reciprocating motion partially inside the casing 4 c. Each driving rod connects to a piston inside a hydraulic cylinder, which is pivotally attached to the base portion. The piston rods 9 e of the pistons 9 are fastened to the common connecting plate 9 c that is also a strong and thick plate and forms a heavy and durable frame for the piston rods 9 e that are fastened with their free end to the connecting plate 9 c with fastening means 9 f such as screws. FIG. 12 presents in a side view, partially cross-sectioned and in a simplified and diagrammatic way the hydraulic cylinder block 7 a according to FIG.

FIG. 11 presents in a side view and in a simplified and diagrammatic way the part of the power-take-off arrangement according to FIG. That makes also the dimensioning in the planning phase easier and simpler. The pair of mutually similar circular coupling elements 8 a is fastened to the first end of a pair of the first lever arms 8 b that are pivoted at their second end to the first end of a pair of the second lever arms 8 c that are further pivoted at their second end to the actuating rod 6 a through a joint pin 8 d that is constantly fastened to the actuating rod 6 a. Thus, the length of the guiding cylinder 6 b is greater than the reciprocating linear motion of the actuating rod 6 a.
However, before the removal of the hydraulic cylinder block 7 a both the free end of the hydraulic cylinder block 7 a and the free end of the guiding cylinder 6 b must be closed and sealed against seawater. For the sake of clarity the closing and sealing mechanism 12 is not shown in FIGS. These reciprocating forces cause extreme fatigue stress to the structure, which leads easily the various fatigue breakdowns. The panel 2 comprises two parallel halves with a vertical gap 2 a extending upwards from the lower edge of the panel 2 in the middle of the panel 2 between the two halves of the panel 2. The upper part of the panel 2 is unbroken without the gap 2 a.
