Embodiment Construction

[0048]The wave 1 shown in Figures 1a and 1b comprises potential energy Ey and kinetic energy Ex. The potential energy Ey is generated by the height change of the water molecules in the vertical direction Y. The kinetic energy Ex is generated by the reciprocating horizontal motion of the water molecules 2 . When the water molecule 2 is close to the valley of the wave 1, its potential energy Ey is low and its kinetic energy Ex is high. The opposite is true for water molecule 2 at the crest of wave 1. Through the action of these two simultaneous energies Ex, Ey, the water molecules 2 move along a circular or elliptical curved path 3 . This movement of the water molecules 2 extends a distance from the water surface 5 to the bottom 6 . The depth to which the water molecules move depends, for example, on the size of the distance from the water surface 5 to the bottom 6 . Similarly, the shape of the curved path 3 depends, for example, on the distance from the water surface 5 to t...

Abstract

The invention relates to a method and a device for recovering energy contained by waves. The collecting device (8) comprises a float (7) coupled by means of one or more support bars (10, 11) to an actuator (12). At least one support bar is rigidly coupled to the float (7) or to a support member (62) in the float. In addition, the float (7) is arranged substantially entirely below water level.

Description

technical field [0001] The invention relates to a method of recovering the energy contained in waves and to a collection device. The objects of the invention are more specifically disclosed in the preambles of the independent claims of the present application. Background technique [0002] Several methods have been proposed for harvesting and converting wave energy into pressure energy. FR publication 2436888 discloses a float on water which is supported to the body of the collecting device by a rod hinged to said float. A hydraulic pump is provided in association with the rod, so as to generate hydraulic power when the float moves under the action of the waves. However, a problem with such collecting devices is that the movement of the buoys is not controllable, so that the energy contained in the waves cannot be collected in a satisfactory manner. Contents of the invention [0003] The object of the present invention is to provide a new and improved method and device ...
