Definitions

  • This invention relates to a wavemotor with basin, where s the wavemotor comprises a number of floating bodies each having a built-in displacement pump.
  • the main task of all wavemotors is to convert the largest possible part of the wave-energy in the sea to a useful energy.
  • Wavemotors of prior art convert only a fraction of the 0 wave-energy into useful energy.
  • One of the reasons for this, is that many of the wavemotors are designed such that they only can absorbe the kinetic energy in the waves from one direction.
  • the third reason is that the absorbed energy often is converted (e.g. from mechanical to electrical energy). This means 0 that the major part of the absorbed energy is lost.
  • the object with this invention is to provide a wave ⁇ motor that converts a much greater part of the wave energy in the sea to useful energy than wavemotors of prior art.
  • the floating bodies follow the complete movements of the waves independent of wave direction and will therefore absorb a much larger part of the kinetic energy in the waves. Further, the design according to the invention causes the pressure against the piston in the wavemotor to be maintained and remain almost constant as the floating body floats higher above the surface, even if the buoyancy decreases.
  • Fig. shows scematically a wavemotor viewed from the side and one o the floating bodies in section
  • Fig. 2 shows anothe embodiment of the wavemotor seen from the top.
  • the wavemotor in Fig. 1 comprises three spheri floating bodies 5, each having a built-in piston pump.
  • Th floating bodies 5 are arranged evenly spaced and rotatably aroun a stable and vertical pipe 4.
  • the piston rods 3 of the pumps ar arranged slanting upwards towards the pipe 4 with their end connected to the pipe 4 via swivel links 2.
  • Each piston rod i therefore movable in a plane through its central axis and th central axis of the pipe 4, at the same time the piston rod i rotatingly connected to the pipe 4.
  • the floating bodies 5 are interconnected by a frame con struction 10 via ball joints 8.
  • the frame construction 10 is i the form of a pyramid with the top turned down, the top compris ing a housing 11 slidingly and jointly connected to the pipe 4.
  • the slide and joint connection is provided by a ball-shape sleeve 12 with a cylindrical bore provided slindingly on the pip 4, the sleeve 12 provided slindingly as a ball joint within th housing 11.
  • Each of the piston rods 3 of the pumps is connected t a double-acting piston movable inside a cylinder 6.
  • the pipe 4 is below the joint connection 11, 12 secure to a large body of little higher specific gravity than the water in which it is located.
  • This body (not shown) can be in the for of a thin-walled container filled with water and which is held in suspension under the water surface as a large inert mass by the floating bodies 5.
  • This inert mass acts like a counter force when the floating bodies 5 move in the waves. The provision of the large, inert mass enables the wavemotor to work independent of the tide.
  • This mode of operation is performed at the same time in all of the floating bodies 5 around the pipe 4.
  • the frame construction 10 enables the floating bodies 5 to move together and follow the movement of the wave in an efficient manner.
  • the wave motor will therefore work efficiently indepen- dent of the direction of the waves.
  • the pressure energy which is developed by the pumping work of the wave motor is absorbed by the water which is pumped and directed to the basin, and which is converted to heat energy at the outlet in the basin where the s pressure is released.
  • the wave motor is located as near as possible to the basin.
  • hoses and pipes guiding the water may be heat-insulated and/or made of an heat-insulating material.
  • the floating bodies are spherical.
  • the floating bodies may also have other forms, such as cylinder or disc.
  • the number of floating bodies may be more than three.
  • Fig. 2 shows a special embodiment of the wavemotor s comprising three spherical floating bodies 5, which on the sides are connected to the frame construction 10 via swivel links 8.
  • the frame construction 10 moves parallel with the pipe 4 and the spherical floating bodies 5 slide along the pipe 4 while at the same time revolving around 0 the links 8.
  • the frame construction 10 may also be in the form of a floating body, such as a floating ring around the pipe 4.
  • the floating bodies 5 will then contribute less to the buoyancy and act more like housings for the pumps. 5
  • a closed system may be used, in which a fluid is recirculated from the basin to each pump whereafter it is pumped and once again supplied to the basin.
  • the wave motor according to o the invention also may be used for other pumping work at sea.
  • the wavemotor may be used i.e. for pumping gas to a pressure vessel for a power plant.

Abstract

Machine exploitant l'énergie des vagues et comportant un bassin, cette machine étant conçue de sorte que ses corps flottants (5) suivent tous les mouvements des vagues et absorbent toute l'énergie des vagues, laquelle énergie peut trouver une application technique sous la forme d'une pression dans un fluide. Cette pression fluidique, qui est de l'énergie, est transformée en chaleur dans un bassin situé à proximité de la machine à une courte distance permettant d'obtenir un facteur d'utilisation très élevé de cette énergie. La conception nouvelle de cette machine la rend stable même par mauvais temps. Ladite machine est utilisable en pisciculture et pour la natation sportive, scolaire et récréative. On obtient une régulation technique de la température de l'eau et de sa composition chimique et physique. Cette machine trouve également application dans une centrale électrique.
