Definitions

  • This invention relates to a device for deriving energy from wave motion of the sea, lakes or other bodies of water (including artificial bodies of water) exhibiting sufficient wave motion to provide a realistic amount of energy.
  • Pelamis device which comprises an elongated floating tube that includes cylindrical sections linked by hinges. The sections move with the wave and are associated with hydraulic rams and motors to drive electrical generators.
  • a device for deriving energy from wave motion of the sea or other natural water source includes an elongate cylindrical body that is mounted in fixed position having regard to the prevailing disposition of one or more wave motions, the cylinder having longitudinal rows of channels or plurality of buckets, the channels or buckets being adapted to receive water from the swell of a wave on one side of the cylinder and to discharge water when those channels or buckets rotate to the other side of the cylinder; and including one or more orifices for air access when on the discharge side of the cylinder; the cylinder being associated with electric generation apparatus.
  • a swell of a wave will cause the channels or buckets on one side to be filled by the water on the leading edge of the swell thereby causing rotation of the cylinder due to imbalance of the channels or buckets on either side, the rotation causing the filled channels or buckets to move through approximately 180 degrees to commence an upwards direction accompanied by the displacement of the water by air as the channels or buckets ascend during their rise on the trailing zone of the swell having just passed the cylinder.
  • the buckets may be mounted on discs or other formations located transversely along the cylinder or directly onto the cylinder.
  • the buckets are mounted in rows, and in an example of the invention the rows of buckets are staggered so that water issuing from buckets in a row above may fall into those of an adjacent row and increase the torque of the device.
  • buckets are replaced by channels or compartments formed in an elongated cylindrical body by means of discs mounted along a cylindrical core at various intervals, and rotors or vanes fixed between the discs.
  • the cylindrical core is preferably fixed to an axle with the axle being coupled directly to one or more large generators to either side thereof.
  • the generators are housed in water-tight containers in order to protect them from the elements and may float on connected side rafts.
  • the rotors or vanes are preferably substantially tangentially attached to the cylindrical core and may be arcuate to increase the volume of fluid captured initially.
  • Figure 1 is a schematic cross sectional view through an example of the invention
  • FIG. 2 is a similar view illustrating an alternative form of the invention
  • Figure 3 is a sketch of the mounting means for the device
  • Figure 4 is a cross-sectional view of a bucket
  • Figures 5 and 6 are perspective views of an arrangement of discs and buckets
  • Figure 7 is a cross-sectional sketch of another arrangement of buckets
  • Figure 8 is a front view sketch of Figure 7,
  • Figures 9 a to c are various perspective views of the preferred embodiment of the cylinder of the invention.
  • Figure 10 is a side view of the cylinder of Figure 9,
  • FIGS 11 a to d are perspective views of a floating cylinder embodiment
  • Figures 12 a and b are perspective views of a fixed cylinder embodiment.
  • FIGS 1 through 8 show one form of the invention (making use of buckets) and these figures are used to illustrate the principle of operation of the invention.
  • a cylinder 10 has a series of discs 12 located along its length at intervals - see Figures 5 and 6. Each disc serves to mount buckets 14 around the periphery.
  • the cylinder axle which may be fixed and non-rotational, is mounted on a sea bed by means of fixed pillars 19 as shown in Figure 3, and including a height adjuster 20 - which may be much more sophisticated and which may follow the level of the surface at all times.
  • An axle holder 21 is also provided. The axle may be adjusted according to the height of the ocean mean level and higher wave top level to entrap as much water as possible.
  • a slot 23 is provided for this purpose.
  • the cylinder has an axle 16 which can be associated with an electric generator so that the rotary motion of the cylinder around the fixed axle is harnessed to produce energy.
  • the buckets may terminate in small orifices 22.
  • Reference to Figure 5 shows the configuration of the buckets around the periphery of a disc.
  • prismatic or conical buckets 50 are provided on discs 52 to reduce water resistance when moving through the water.
  • the buckets should be positioned for the balance of the device to be balanced when the buckets are either full of water or empty.
  • the device may be free to bob up and down in deep water swells as indicated by arrows 100. It can only rotate in one direction because the buckets can only be filled with the wider open ends upwards and this side must descend whatever direction the swells come from.
  • the same pillar supports may be used with the axle moving vertically within the vertical slots locating it.
  • the buckets are replaced by channels or compartments 60 formed in an elongated cylindrical body by means of discs 62 mounted along a cylindrical core 64 at various intervals, and rotors or vanes 66 fixed between the discs.
  • the cylindrical core is preferably fixed to an axle 68 with the axle being coupled directly to one or more large generators 70 to either side thereof.
  • the generators 70 are housed in water-tight containers 72 to protect them from the elements and may float on connected side rafts (74 in Figure 12).
  • the cylindrical core is supported by a radial strut system 76 with the struts being fixed to the cylindrical core and the axle drive shaft 68.
  • the channels or compartments include one or more orifices 78 for air as described above. These are essential to release the vacuum which would otherwise draw the fluid upward on either side of the wave, reducing the gravitational downward forces on the wave impact side. This avoids the possible balancing of the cylinder into an undesirable state of equilibrium.
  • the cylinder floats and drives external generators as shown in Figures 11 a to d and the second in which the cylinder is fixed and drives external generators. This embodiment is shown in Figures 12 a and b.
