Abstract

A marine current mill comprises a floating paddle wheel 1 attached through a structure 4 to a mooring 8. The movement of waves causes the wheel to rotate, producing mechanical energy which can be converted into electrical power using a generator. Waterproof compartments 6 in the paddle wheel 1 keep the device afloat. The mill may also be used to produce hydrogen or provide desalination of sea water.

Description

<p>1 2435494 Floating Marine Current Mill The present invention is a
device producing power by transformation of the kinetic energy of marine or river current. It is characterized by getting at least one paddle wheel with its axis orientated parallel to the sea surface and perpendicular to the current flow. This paddle wheel floats itself so that his paddles below dive in the water, and his upper paddles get out of the water.</p>
<p>The paddle wheel which can freely rotate about his axis is attached by a structure which is linked to a mooring tightly maintaining it in position and preventing the whole device to drift with the current.</p>
<p>Thus the paddle wheel rotates by action of the water current which pushes on his submerged paddles.</p>
<p>A power generator driven by the wheel motion converts a part of the rotation energy of the wheel in electric power. The generator may be direct driven or not, inside or outside the paddle wheel, set on the structure. The electric power is eventually exported to the shore in order to be connected to the grid.</p>
<p>In other applications, the device can eventually be used for electrolysis of water in order to produce hydrogen or to produce fresh water from sea water for instance.</p>
<p>The already known devices for this usage are currently underwater and fully submerged devices, using one or several horizontal shaft propellers rotating in a perpendicular plane to the current.</p>
<p>Unfortunately, these systems need big infrastructures, set on the seabed for maintaining the propeller in the water. These infrastructures are costly to carry out, to maintain and dismantle while, the device itself, being submerged, is costly to manufacture.</p>
<p>The purpose of this invention is to drive these costs down by carrying out a device floating at the surface of the sea. Thus the device can easily be moved, removed and maintained. This floating device is regularly moored and doesn't need other fixed infrastructure than an anchored device on the seabed.</p>
<p>Another advantage is that the device by floating itself instead of being supported by floating pontoons is more resistant and less costly.</p>
<p>The invention will now be described solely by way of example by referring to the accompanying drawings, this drawings being non restricted of the invention itself as described above: Figure 1 shows the device from the side *.es Figure 2 shows the device from the top S...</p>
<p>Figure 1 shows an exemple of the device including a paddle wheel (1) with 16 paddles (2) and a waterproof compartment (6) . The shaft (3) is maintained by a structure (4) through two bearings (5) allowing the paddle wheel (1) to rotate freely activated by the current (7) while the whole device is attached to a mooring (8) Figure 2 shows a solution of electric generator by direct drive even though other types of generators can be used. It includes permanent magnets (10) set on the interior of cylinder (6) while the stator (11) is set to the shaft (3) and the mechanical structure (4) * S</p>
