The present invention relates to the utilization of wave energy and its conversion into operating motion of an electrical energy generating system. The system for generation of electrical energy through the conversion of aquatic wave motion includes floating bodies and a constant rotation mechanism, which converts the two-way linear motion of an inflexible transmission shaft or a flexible transmission shafts into one-way rotation of an output shaft of the constant rotation mechanism. This mechanism allows utilization of wave energy in two directions caused by the rise and fall of waves. The output shaft of the constant rotation mechanism is coupled to a force multiplier that is further coupled to a generator which generates electrical energy. Constant rotation mechanism can be driven by inflexible transmission shaft pivotally coupled to the floating bodies at one end, and the other end to an input gear of the constant rotation mechanism. Depending on the height of the wave and the wavelength, various constructions of floating bodies are used. Certain floating bodies are designed for the waves of a smaller amplitude and smaller wavelength, while other floating bodies are designed for bigger amplitude and bigger wavelength.

Disclosed herein is a method for determining the arrangement of wave energy converters in a wave power park in a seabed or lake area including the steps of: measuring wavelength and wave direction over a period of time, collecting all values measured for the wavelength and the wave direction in a matrix, statistically determining, from the matrix, a predominant wavelength and a predominant wave direction, and arranging an amount X of wave energy converters at regular intervals over a distance that corresponds to half of the length of the predominant wavelength or a multiple thereof, where the distance is measured in a direction at least more or less parallel to the predominant wave direction.

By providing the central portion with a bell mouth opening and attachment means for a wire or rope, a buoy with improved characteristics is provided.

The magnetic array chamber is housed inside the lower cylindrical frame and may have a magnetic array axle with plurality of fixed magnets on it. The magnetic array axle may protrude into the frictionless levitation chamber and have a magnet attached to it. The floating inductive coil is located externally of the lower cylindrical frame.

Disclosed are a wave power generation system for generating electrical energy by means of a hydraulic circuit, and a method for controlling same. The wave power generation system comprises a hydraulic motor for storing motion energy in a form of fluid pressure and volume if a plurality of tension transmission members, for transmitting motion energy by means of six-degrees-of-freedom motion of a movable object floating on the waves, move in one direction, and for maintaining the tension of the tension transmission members by means of the stored energy if the tension transmission members move in the other direction. Electric energy is alternately generated by means of the bidirectional motion of the plurality of tension transmission members.

The invention relates to a device that uses wave energy to convert it into electrical energy via hydraulic energy. This device is installed on marine structures with vertical walls and comprises: a free floating elementing element that exploits the vertical sea level variation due to the swell, guided by a triple rail lateral movement channeling system installed on vertical walls; a support connecting the floating elementing element to a hydraulic system of cylinders allows the conversion of mechanical energy into hydraulic energy in both directions of movement, up and down; an energy amplification system to optimize the efficiency of the device; a hydraulic power plant; pressure accumulators; an oil tank and a hydro-electric turbine that allow the conversion of hydraulic energy into electric energy.

A system includes a float including a drivetrain, a reaction structure coupled to the drivetrain by a tendon, and an extension spring having a first end coupled to a fixed point on the tendon and a second end configured to be disposed at a fixed location relative to the drivetrain. The extension spring is configured to experience an elastic force in response to tension on the first end of the extension spring away from the drivetrain.

The present invention provides a system and method for converting wave energy into electric energy in an intelligent, practical, and efficient manner. The system utilizes a power input shaft coupled with a vertically reciprocating buoy to rotate a crank gear and a ratchet gear meshing therewith. An intelligent control system is included to monitor, control, and optimize the operations of the system. The length of the power input shaft is adjusted in response to water level fluctuations so that the rotational motion of the crank gear is intelligently controlled within a predetermined desirable region for maximum efficiency.

An elongate energy conversion device vertically oriented in a body of water with an oscillating core that converts wave movement into oscillating movement of a central housing, the housing including a set of ballscrews and threaded shafts which are then rotated and attached with generators to convert the rotational motion into electrical energy. The oscillating core is substantially enclosed by a movement resistant shell with a horizontally-extending heave plate which actuates the core depending on whether the oscillating core is being pulled upward from an attached float impacted by a wave crest or downward from an attached weight during a wave fall.
