Abstract

The device for conversion of wave energy into electrical energy consists of a supporting structure, the first working body, an anchor and anchor cables. The supporting structure is connected to the anchors by anchor cables, while the first working body is slidably connected to the supporting structure. The motion transformation system is firmly connected to the supporting structure and comprises rigid gears toothed with gears with rolls on one side while on the other side they are hinged to the first working body, on the other side of the gears with the rolls, rigid gears are connected at one end, while their other end is hinged to other working body. The gears with rolls are connected by shafts with a multiplier that drives the generator that further produces electricity. The device constructed in this way has the possibility of transport to the place of exploitation, because it floats stably on its own. The anchor system is transported to the place of exploitation using a transport body that also has the ability to float on its own and to submerge.

Dependent claims

A device for conversion of wave energy, of body of water having a water surface and a seabed, into electrical energy wherein the device comprises:

a support structure, that is configure to float above the seabed,
a series of anchors positioned on the seabed and configured to secure the position of the support structure by use of tethers;
a first working body that is slidably connected to the support structure and is configured to float at or near the surface of the body of water and move in a vertical direction;
a first vertically oriented rigid gear rack that is pivotally coupled to the first working body at a first end of the first working body, the first gear rack configured to move vertically with vertical movement of the first working body, the first gear rack configured to engage and rotate a pinion gear that is coupled to a generator upon vertical movement of the first gear rack;
a second working body that is slidably connected to the support structure;
a second vertically oriented rigid gear rack that is coupled to the second working body at a first end of the second working body, the second gear rack is generally parallel to the first gear rack and is connected to the pinion gear, wherein the second working body provides a constant load to tension the first and second gear racks and wherein upward vertical movement of the first working body causes downward vertical movement of the second working body;
and wherein the anchors can be transported independently of the support structure.
