US10151293B2 – Energy Transfer Arrangement Of A Wave Energy Recovery Apparatus – Google Patents

The cylindrical piston 9 is placed inside the hydraulic cylinder 7 a so that between the closed end or the second end of the hydraulic cylinder 7 a and the second end of the piston 9 there is a sealed pressure space 9 a that is filled with hydraulic fluid that is circulated in the hydraulic circuit of the hydraulic PTO unit 7 for converting the captured wave energy for instance to electric energy. Results comparable to those for FIG.

8, which shows the voltage output achieved with the same system as for FIG. 4a-4 c. Only two magnets and two coils are illustrated in this example for purposes of simplification, but normally larger numbers would be desired, the principal constraint being space limitations. 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. 7 and 8. For the sake of clarity the closing and sealing mechanism 12 is not shown in FIGS. That can be done for instance with a same kind of closing and sealing mechanisms 12 that are described in connection with FIGS.

While the values of the maximum voltages for the system of FIG. This position corresponds to a maximum rate of flux change in a vector direction opposite to that corresponding to FIG. It is believed that the overall power output was hampered due to the presence of remnant magnetic flux inside the coil even when one of the magnets had moved beyond it. Nervios y dolor de espalda . This resulted from the successive magnets having a common polarization vector, so that along the axis between the magnets the flux entering the south end of one magnet was in the same direction as the flux leaving the north end of the next magnet.

Redcord en Dolor de Hombro-Tratamiento eficaz - Osteopatía The same conical or spherical forms apply also to the first end of the driving and power-take-off arrangement 5 with the pusher end 6 e of the actuating rod 6 a. After that the hydraulic cylinders 6 b and 7 a are fastened to each other and the closing and sealing mechanism 12 is opened, after which the power transmission mechanism 6 d, 9, such as the piston 9 is unlocked inside the hydraulic cylinder 7 a and the first end of the power transmission mechanism 6 d, 9 is moved into the guiding cylinder 6 b, 13 in a touching contact with the pusher end of the actuating rod 6 a.

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 case of the electric mechanism one of generators 15 can be used as an electric motor pushing the pinion rack 6 d towards the pusher end 6 e, 6 f of the actuating rod 6 a, and the rest of the generators of one PTO unit 7 rotate freely without resisting the return motion of the pinion rack 6 d. Electric power for the return pushing of the pinion rack 6 d is taken from the other PTO unit 7 that is currently generating electric energy.
