Definitions

  • the present invention relates to power-generating equipment, more particularly a floating sea wave power-generating plant driven by the kinetic energy from sea wave.
  • Wave energy converter (WEC) devices generally fall into one of the following categories:
  • Some examples include the Pelamis, McCabe Wave pump, Archimedes wave swing, Nodding duck and the IPS buoy, each of which have had some limited success but are know to have some shortcomings, especially in areas where the seas are significantly large.
  • the size and strength of ocean waves fluctuate depending on a number of factors, such as wind speed, how long the wind has been blowing, tidal movement and depth of ocean.
  • the resultant waves then can have differing energy potentials that can be difficult to harness if the WEC is not properly designed to withstand the high seas that can form in the open ocean. So far, no economic and efficient wave power-generating device has been found.
  • the objective of the present invention is to provide a floating wave power-generating plant for solving the problem of power generation by the use of wave energy.
  • wave period refers to the time that elapses between successive peaks or troughs of a wave passing a fixed point.
  • a floating wave power-generating plant includes floats suspended on the sea wave, furthermore includes a supporting frame floated on the sea wave with sufficient length, on said supporting frame a long shaft and power generator are mounted, and a sprocket wheel assembly is mounted on said lengthened shaft, and said supporting frame is held by means of anchor.
  • Said floats consist of static float and dynamic float, the static float and dynamic float can be arranged one after another and spaced at interval, said static float is fixedly connected with the supporting frame, on the upper portion of said dynamic float a vertical rod is mounted, said vertical rod is provided with a chain, said chain is meshed and connected with the sprocket wheel assembly on short shaft, every dynamic float is respectively connected with the sprocket wheel assembly on every short shaft through the vertical rod, every short shaft is connected together through shaft coupling to form a long shaft with sufficient length, said long shaft is connected with the power generator by means of transmission assembly.
  • Said sprocket wheel assembly is provided with a ratchet, and the sprocket can be driven to make the long shaft be rotated as a part of dynamic floats move upwards along with the motion of sea wave, thus power can be generated by the power generator, while the sprocket will be made to run idly as said part of dynamic floats move downwards along with sea wave motion.
  • the wave power-generating plant of the present invention is a power generator floated on the sea wave, which can generate power by harnessing wave energy in any sea area.
  • said supporting frame with sufficient length and for mounting long shaft and power generator can be fixed on a plurality of floats mentioned as static float, to make said frame be floated on the sea wave. Because the frame extends with sufficient length and the static floats have enough quantities, the influence of sea wave motion on the supporting frame is very little.
  • the supporting frame is held through the anchor, the supporting frame is basically rested on the sea wave, thus a platform of wave power-generating plant can be formed. On such a platform power generator can be installed to generate power, resulting in a wave power-generating plant.
  • a floating wave power-generating plant said plant includes floats suspended on a sea wave, the sea wave having a wave period T, a supporting frame floated on the sea wave, at least two dynamic buoys/floats positioned to contact the sea wave and move substantially transverse to the supporting frame, by the action of the sea wave, each dynamic buoy/float includes a vertical rod, on said supporting frame a linear shaft and power generator are mounted, and a sprocket wheel assembly is mounted on said shaft, the vertical rod and sprocket wheel operatively engaged so that reciprocal movement of the vertical rod translates in to rotational movement of the linear shaft, and said supporting frame is held by means of anchor, characterised in that the linear shaft has a length L that is approximately equal to or greater than the wave
  • the linear shaft includes a plurality of short shaft each connected one to the other
  • the frame is open to allow the sea wave to pass through.
  • the dynamic floats are housed or contained in modular units to allow for straightforward changes to the plant as a whole to be made, such as making the overall plant longer or shorter dependant upon the wave period, or average wave period, of the seas that it is positioned.
  • Figure 1 is the structural diagram of a floating wave power-generating plant in the present invention.
  • Figure 2 is the enlarged structural diagram of wave power-generating plant in Figure 1 that is equipped with three dynamic floats.
  • Figure 3 shows the wave power-generating plant in a body of water, with the dynamic floats at varying positions.
  • a floating wave power-generating plant of the present invention said plant includes floats suspended on the sea wave, furthermore includes a supporting frame 9 floated on the sea wave with sufficient length, on said supporting frame 9 a long shaft 10 and power generator 1 are mounted, and a sprocket wheel assembly 7 is mounted on said long shaft 10, and said supporting frame 9 is held by means of anchor.
  • the supporting frame is manufactured in an open manner, such as from a scaffold material or similar so to allow water and air to flow through it.
  • Said floats consist of a plurality of static floats 8 and dynamic floats 6, the static float 8 and dynamic float 6 can be arranged one after another and spaced at interval.
  • one static float 8 is arranged to space at interval with every three dynamic floats 6 that compose as a whole.
  • said static float 8 is fixedly connected with the supporting frame 9, namely said supporting frame 9 for mounting the power generator 1 is installed on a plurality of static floats 8, said supporting frame 9 can be floated on the sea wave by means of buoyant force of the static floats 8.
  • the number of static floats 8 and dynamic floats 6 can be set as several tens, even several hundreds.
  • Said dynamic floats 6 are floated on the sea wave, and said dynamic floats move upwards and downwards along with the wave under influence of sea wave.
  • a vertical rod 61 is mounted, said vertical rod 61 is provided with a chain, said chain is meshed and connected with sprocket wheel assembly 7 mounted on short shaft 4. Every said dynamic float 6 is respectively connected with each sprocket wheel assembly 7 on short shaft 4 through said vertical rod 61 , namely one sprocket wheel assembly 7 is connected with one dynamic float 6.
  • Every short shaft 4 is arranged in a bearing seat 3, said bearing seat 3 is mounted on the supporting frame 9.
  • Each of short shafts is connected together through a shaft coupling 5 to form a long shaft 10.
  • Said long shaft 10 is connected with power generator 1 by means of transmission assembly 2, and the rotating speed of said long shaft 10 can be converted into the rotating speed required by the power generator by means of transmission assembly 2.
  • Said sprocket wheel assembly 7 is provided with a ratchet, the sprocket can be driven to make the long shaft 10 be rotated and cause the power generator 1 to generate power as a part of dynamic floats 6 move upwards along with wave motion, and the chain on said vertical rod 61 is driven to move upwards together; while the sprocket will be made to run idly as said part of dynamic floats 6 move downwards along with wave motion under influence of ratchet. However, another part of dynamic floats 6 will move upwards again by the action of wave motion, to drive the sprocket and make the long shaft 10 be rotated. Because there are always dynamic floats 6 that move upwards along with wave motion to drive the long shaft 10 be rotated at any time, therefore the power can be continuously and stably generated by the power generator 15 so as to become a wave power-generating plant.
  • three dynamic floats 6 can be composed as a group, and on every dynamic float 6 a roller 62 is mounted, and a guideway can be fixedly mounted on the supporting frame 9, said roller 62 rolls in the guideway, thus said dynamic floats can be caused to move upwards and downwards in a straight line along the guideway, which ensures the accuracy of engagement between the chain on the vertical rod 61 and the sprocket on the sprocket wheel assembly 7, thus to drive the long shaft 10 to be rotated.
  • the long shaft 10 in combination with the short shafts 4 have an overall length L, and this length can be altered by removing or adding on additional units, each of which have their own dynamic float.
  • Each dynamic float is housed in a separate modular unit, so in this manner it is easy for the plant as a whole to be lengthened or shorted so that an array can be readily constructed depending on the size of the seas to which the plant is to be positioned.
  • the modularity of the units makes it easy to perform maintenance as units can be readily removed and added as required.
  • Waves have a period, or length, T, which is the length as measured between the crests, or troughs, of two adjacent waves. If the overall length L of the shafts is less than the wave period T then the floating wave power-generating plant will be unstable and some of the buoys will not be efficient in turning the shaft as they will not move significantly. This will result in sporadic rotation of the long shafts 10 and thus the power output of the plant will be reduced and the stability of the plant is compromised, which can result in it capsizing.
  • the wave moves the dynamic floats ⁇ to varying positions making the shaft 10 rotate in a consistent manner.
  • the present invention fixes this issue by having ensuring that L is equal to or greater than the wave period T, so that the buoys/floats that first contact the wave front will move upwards and as the wave moves along the length of the plant each buoy will rise and fall in succession, without decreasing the stability of the plant.
  • the surging wave can pass through the frame, without greatly contributing to the destabilisation of the plant

Abstract

La présente invention concerne une centrale flottante houlomotrice. La centrale comprend des flotteurs suspendus sur les vagues de la mer, ainsi qu'un bâti de support de longueur suffisante flottant également sur les vagues de la mer, un arbre long et un générateur d'énergie étant montés sur ledit bâti de support, tandis qu'un ensemble roue dentée est monté sur ledit arbre allongé. Les flotteurs sont constitués par un flotteur statique et un flotteur dynamique, le flotteur statique et le flotteur dynamique pouvant être disposés l'un après l'autre, le flotteur statique étant relié de façon fixe au bâti de support, et une tige verticale étant montée sur la partie supérieure dudit flotteur dynamique, laquelle est reliée de façon fonctionnelle à un ensemble roue dentée sur chaque arbre court. Les arbres courts sont reliés entre eux par l'intermédiaire d'accouplements d'arbre de façon à former un arbre long avec une longueur L, et sont reliés à un générateur d'énergie à l'aide d'un ensemble transmission. La centrale a une stabilité accrue dans tous les états marins, et une sortie d'énergie constante du fait de la corrélation de la longueur de l'arbre avec la période de la vague.
