Definitions

  • This invention relates to a wave-powered generator. More particularly, it relates to a wave-powered generator device including a shaft mainly horizontally arranged and being rotatably supported in a structure, and the shaft being connectable, in terms of transmission, to an energy machine, and there being, rotationally fixed to the shaft, at least one buoyancy body which is arranged to follow a rising and falling wave motion, the centre of buoyancy of the buoyancy body being at a radial distance from the centre axis of the shaft.
  • the invention also includes a method for a wave-powered generator.
  • Wave-powered generators are known in many designs that can apply various principles to extract wave energy and convert it into electrical energy, for example.
  • An example of such a power plant is described in NO 305410 in which a wave-powered generator includes at least one channel, which is defined externally by a hollow column and is supplied, from below, with water via at least one opening.
  • a piston Internally in the hollow column, a piston is arranged, which is arranged to rise and fall with the inflow or outflow of water through the opening, the reciprocating upward and downward motion of the piston being convertible into one rotating motion in one and the same direction.
  • the corresponding rotational energy can be converted into electrical energy, for example.
  • the device according to NO 305410 is relatively space-demanding and thereby less suitable for, for example, retrofitting on existing installations offshore, such as windmills and petroleum installations.
  • the US document 2013/0287573 shows a system for capturing wave energy, in which a float that runs in a vertical slot is connected by means of a crank device to a horizontal shaft.
  • the GB document 2429045 discloses a tidal power station in which a float is hingingly connected to an arm on a shaft.
  • the US document 625101 deals with a so-called wave-motor in which a float is attached to a shaft by means of an arm.
  • None of these devices mentioned includes features, which are considered necessary to achieve the desired efficiency in a wave-powered generator of this kind.
  • the invention has for its object to remedy or reduce at least one of the drawbacks of the prior art or at least provide a useful alternative to the prior art.
  • a preferably horizontal shaft is rotatably arranged in an existing structure or a new one.
  • the shaft is provided with at least one buoyancy body, the centre of buoyancy of the buoyancy body being at a radial distance from the centre axis of the shaft.
  • the buoyancy body is near a wave surface and may, depending on its position, be above the wave surface, in the wave surface or submerged under the wave surface.
  • the radial distance between the centre axis of the shaft and the centre of buoyancy of the buoyancy body is adjustable by means of an actuator.
  • the buoyancy body is arranged to follow the wave motion up and down, but also the horizontal velocity component of the waves, thus imparting an alternating rotary motion to the shaft.
  • This rotary motion and the corresponding energy may be converted, in a manner known per se, into, for example, electrical energy or pressure energy.
  • the invention relates more specifically to a wave-powered generator device including a shaft mainly horizontally arranged and being rotatably supported in a structure and being connectable, in terms of transmission, to an energy machine, and there being, rotationally fixed to the shaft, at least one buoyancy body which is arranged to follow a rising and falling wave motion, the centre of buoyancy of the buoyancy body being at a radial distance from the centre axis of the shaft and the radial distance between the centre axis of the shaft and the centre of buoyancy of the buoyancy body being adjustable, and the device being characterized by an actuator being connected between the shaft and the buoyancy body and arranged to adjust said radial distance.
  • the centre of buoyancy of the buoyancy body is meant, here, the centre of gravity in terms of buoyant force, which is the centre of gravity of the displaced liquid. This in contrast to the centre of mass of the buoyancy body.
  • the centre of mass of the buoyancy body may be different from the centre of buoyancy, for example if the buoyancy body is made from materials of different specific gravities.
  • the centre of buoyancy also changes according to how deep into the water the buoyancy body is and, of course, does not exist if the buoyancy body is above the wave surface.
  • buoyancy body By rotationally fixed to the shaft is meant that the buoyancy body rotates together with the shaft.
  • energy machine is used for a device, which is arranged to convert energy, for example from mechanical energy into electrical energy or pressure energy.
  • one buoy- ancy body is arranged at each end portion of the shaft.
  • the shaft is above the wave surface, but cases in which it is appropriate to arrange it near the wave surface, that is to say in a position in which it is washed over by the waves, or below the wave surface can also be envisaged.
  • the shaft may be formed as a crankshaft or be provided with an eccentric collar to provide for the use of a linkage.
  • the linkage is connected between the crank of the shaft, or the eccentric collar, and a mechanism for converting a reciprocating motion into a rotary motion.
  • a mechanism for converting an alternating rotation into a unidirectional rotation may be connected to the shaft without first converting the motion into an axial motion.
  • NO 163544 The mechanism for converting a reciprocating motion into a unidirectional rotation is known to a person skilled in the art, for example from NO 163544, and is not described any further. NO 163544 also discloses a solution for converting a reciprocating rotation into a unidirectional rotation.
