Patent ID: 7989975

Claim:
An appliance for the conversion of wave energy into electrical energy, including a closed float element ( 1 ) and a bob element ( 2 ), with the bob element ( 2 ) being placed inside the float element ( 1 ) and mounted to be mobile in relation to the float element ( 1 ), with the bob element ( 2 ) being designed to be driven into relative movement in relation to the float element ( 1 ) under the action of the waves on the float element ( 1 ), characterised in that it also includes locking means ( 13 , 50 - 59 ) designed to lock the movement of the bob element ( 2 ), and control means designed to control the locking means ( 13 , 50 - 59 ) so as to selectively lock or release the bob element ( 2 ) in order to amplify the movement of the bob element ( 2 ) by continuously adapting the dynamic of the appliance to the waves, wherein the bob element ( 2 ) is free to rotate about a rotation axis, with the movement of the bob element ( 2 ) not being limited by a limiting device, said appliance including a power recovery device that includes a multiplicity of windings ( 81 ) positioned in a fixed manner in relation to the float element and a multiplicity of magnets ( 82 ) positioned on the bob element ( 2 ), wherein when the bob element ( 2 ) is driven in rotation in relation to the float element ( 1 ), an electric current is generated in the windings ( 81 ).
