Definitions

  • the present invention relates to a method and a device for converting wave energy into a form of energy that can be used in practice, particularly for convert ⁇ ing wave movement into a rotational movement.
  • the object of the invention is achieved by a method of converting wave energy into a form of energy which can be used in practice, with the features which appear from claim 1.
  • the invention also provides a device for converting wave energy into a form of energy which can be used in practice, compris ⁇ ing an elongated, preferably cylindrical body which is provided along the periphery with longitudinal vanes, this device having obtained the features according to claim 3.
  • FIG. 1 is a side view of a device according to the invention, anchored floating on the surface of a sea or lake,
  • FIG. 2 is a side view of part of the device in FIG. 1 .
  • FIG. 3 is an end view of the device in FIG. 1 , FIGS. 2 and 3 being shown on a larger scale.
  • the device for carrying out the method according to the invention is designated generally by reference 1 and is shown floating on the surface of a sea or a lake where waves occur.
  • the device is anchored by means of the bottom footings A and B and ropes a and b connected thereto, with the longitudinal axis sub ⁇ stantially in the surface of the water and at an angle to the prevailing direction of the wave fronts.
  • the mooring forces are small while at the same time the device tends to adjust itself in a favourable working position in relation to the direction of the waves. It may suffice to provide an anchoring device at one end only and not at both ends as shown here.
  • the device 1 comprises a cylindrical body 4 with vanes 2 which extend axially along the body and project therefrom at an angle to the radial direction, the outer portions of the vanes being bent at an angle.
  • the vanes may, however, also be arranged flat and/or curved. They can also be arranged with a pitch along the outer sur ⁇ face ' of the body, which is particularly advantageous if the device according to the invention is intended to work in breaking waves, since a device constructed in this manner permits conversion of some of the "horizontal" kinetic energy of the wave into rotational movement.
  • Partitions 3 are arranged radially and extend peripherally round the body axially spaced. They may,
  • the reaction forces during the rotation of the device can be taken up by a floating platform anchored stationary or by a construction fixed to the bottom.
  • the stator of an electrical generator is then disposed on the platform or the construction fixed to the bottom, while its rotor is connected to the rotating body. It is also possible to connect two bodies adapted to rotate in opposite directions. In such a case, the stator of the generator is connected to the one body and its rotor to the other body.
  • Holes 5 may be provided in the vanes 2, as shown in FIG. 3, through which air can .pass in under the vanes at the side 2a when the device moves upwards. As a result of the fact that air passes in through the vanes, these release more easily the water which is present at the ' bottom side of the vanes. Otherwise, this water can exert a braking force on the rotating device. Water, however, does not pass through the holes 5 as easily as air and in this manner the openings act as non-return valves. Nevertheless, the openings 5 may also be provided with valve bodies which are open in the upward-moving part of the device but which close when they come into the downward-moving part 2b, FIG. 3, of the device. These valve bodies may consist of some form of flap.
  • the device according to the present invention thus consists of a simple movable body to which an electric generator, for example, can be connected directly or through a simple transmission.
  • the device can be given an uncomplicated shape, which provides a simple and sturdy construction with great stiffness, suitable for the manufacture of large series from cheap material .
  • the device according to the invention can also be de- signed so that it can stand up to storms and even is able to take up energy from storm waves.
  • the device can be mounted in a construction fixed to the bottom with the longitudinal axis of the body . substanti al ly in the surface of the water.
  • the body does not necess ⁇ arily have to be a floating body. Nor does it need to be a body of revolution but may have a polygonal shape

Abstract

Procede et dispositif de conversion d'energie en une forme d'energie pouvant etre utilisee en pratique. Le dispositif comprend un corps allonge (4) qui est pourvu le long de sa peripherie d'aubes longitudinales (2), disposees angulairement par rapport a la direction radiale, au moins sur leurs parties externes. Les aubes definissent des chambres qui sont delimitees axialement par des parois (3) le long de la peripherie du corps, lesquelles parois sont disposees angulairement par rapport aux aubes. Les aubes permettent une plus grande capacite de deplacement d'un cote de l'axe longitudinal du corps que de l'autre cote de sorte que le corps est force de tourner par les mouvements des vagues lorsqu'il est ancre, l'axe longitudinal se trouvant sensiblement a la surface de l'eau.
