Definitions

  • the present invention relates to a device for controlling a towed floating mobile for the generation of a wake wave.
  • the device for generating at least one artificial wave may also be equipped with a power variator making it possible to reverse the direction of movement of the motor cable, thus moving the mobile in the other direction and this before the traction link do not go around at least two pulleys.
  • the patent EP 2868358 also describes the possibility of using a symmetrical mobile. Indeed the choice of a symmetrical floating mobile simplifies the use of the wave generator device and avoids having to return the mobile before each change of direction of movement. The rotation of a floating mobile several meters long and several hundred pounds can prove to be restrictive, moreover if the water is agitated or exposed to the wind.
  • This ballast may consist of a volume of ballast water which can easily be implemented, which requires only very few technical means and which has high reliability.
  • ballast with water greatly facilitates the modifications of said ballasting by simple variation of the volume of water.
  • the displacement of the ballast water inside the mobile is controlled, the displacement of the ballast water and the variation of attitude generated by the mobile can help to control the movement of the mobile in the conditions sought.
  • ballast water to slow the hull.
  • the water transferred to the front of the hull with respect to the direction of movement, can allow a mass transfer on the front of the hull and therefore a hydrodynamic slowing down due to the pronounced depression of the hull. in water.
  • the displacement of the water must be rapid in order to benefit from the effect resulting from the positioning of the water both for the initial acceleration and for the slowing down of the mobile. Nevertheless, the displacement of the water must not disturb the behavior of the mobile during the phases of acceleration, navigation at constant speed and braking. Indeed, during the acceleration, if the volume of ballast water moves too quickly towards the rear part of the mobile, considered in relation to the direction of travel, it could create a depression of the back of the mobile too fast . Above all, the rapid arrival of ballast water on the back of the mobile generates a force whose component is directed towards the rear, opposite to the direction of traction of the mobile and therefore inverse to the direction of movement of the mobile. This force therefore comes briefly but massively in resistance to the tensile force of the motor cable and the traction link.
  • control means for controlling the hydraulic flow to slow down and control the movement of the ballast water.
  • control means must also be adjustable to let the desired quantity of ballast water and the speed chosen, or to adjust the navigation parameters of the barge according to the selected wave sport practice.
  • the present invention aims to propose means for controlling the displacement of the ballast water in a hull intended to generate a wake wave, in order to obtain progressive variations in attitude of the hull.
  • the elevation view of the figure 1 shows a floating mobile 10.
  • Said floating mobile 10 is symmetrical with respect to a transverse and longitudinal median plane, and has a rectangular section in the embodiment shown.
  • Said floating mobile 10 is provided with two longitudinal edges 12, two rear tables 14 and a folded plane 16 constituting the bottom V of said floating mobile 10.
  • the top of the fold of the folded plane 16 is oriented downwards, forming a keel line 18.
  • the longitudinal direction of the mobile 10 is defined as being parallel to the keel line 18 which constitutes the bottom V of the mobile 10.
  • the longitudinal direction of the mobile 10 is defined as being parallel to the keel line of the V mobile 10.
  • the mobile 10 is provided with flow control means 20, in this case at least one plate 22 positioned vertically inside the mobile 10.
  • the shape of the plate 22 is pentagonal and such that the lower edge matches the formed V by the folded plane 16.
  • the dimensions are almost similar to those of the rear tables 14, the height may be slightly lower.
  • the plate 22 is fixed transversely. Fixing the plate 22 on the hull of the mobile of the mobile 10 may be performed by gluing or welding, for example, depending on the nature of the materials used.
  • the flow control means 20 comprise rounded cutouts 23 on the two lower edges of the pentagonal plate 22 such that said rounded cutouts 23 create orifices 24 when the plate 22 is fixed to the mobile 10.
  • the transverse position of the plate 22 thus represents a brake to any longitudinal flow of the ballast water in the mobile 10, while allowing the water to pass through the rounded cutouts 23.
  • the flow control means 20 may consist of a plate 22 provided with an opening 26 and at least one adjustable closure means 21 of the opening 26.
  • Said opening 26 may be circular or parallelepipedic shape.
  • Said at least one adjustable closure means 21 is composed of a flap 28 and at least two guide rails 27.
  • the flap 28 further comprises several bores 30, positioned vertically in the center of the flap 28.
  • the plate 22, provided with the opening 26, comprises a tapping, not shown, located above the opening 26 and in the middle of the plate 22.
  • a screw for example, not shown, placed through one of the holes 30 and screwed into a thread, positions the flap 28 at the chosen height.
  • the figure 4 represents a transverse section of a symmetrical mobile provided with at least one pallet 34, in this case four pallets 34.
  • Each at least one pallet 34 is positioned vertically at the bottom of the symmetrical mobile and transversely to the longitudinal axis of the symmetrical mobile.
  • Each pallet 34 is fixed to the mobile 10 by gluing, welding or by any other fastening means providing rigid support on the plate 22 to form a baffling.
  • FIG. 5 and 6 Another variant for controlling the flow of ballast water is represented on the Figures 5 and 6 .
  • the elevational view of the mobile 10 represents at least one convex element 36, in this case four convex elements 36.
  • Said convex elements 36 are arranged successively, longitudinally and are positioned at the bottom and orthogonal to the longitudinal axis of the mobile 10 Said convex elements are fixed on the folded plane 16 which form the bottom V of the mobile 10 and are folded at the edge of the bottom V.
  • Said convex elements measure about twenty centimeters in height to give an idea.
  • Each convex element 36 is formed monolithically by a curved metal plate or a solid element shaped like wood for example.
  • FIG. 6 Another variant, represented on the figure 6 , comprises a horizontal plane 40 provided with a curved plane 42 at each longitudinal end of the mobile 10.
  • the horizontal plane 40 is positioned and fixed at the junctions between the folded plane 16 and the longitudinal edges 12. The operation of the previously described devices is now explained.
  • the plate 22 positioned transversely to the longitudinal direction of the mobile 10 slows down the flow of water while allowing the water to pass through the openings 24.
  • the cable has an arrow and therefore the angle of incidence of the mobile 10 relative to the surface of the water decreases.
  • the advantage is that the time of passage of water can compensate gradually as the angle decreases by increasing the weight on the back. There can therefore be a calculation of the flow of the ballast water as a function of the movement of the mobile 10.
  • the ballast water is caused to move towards the front of the mobile 10.
  • the ballast water is slowed by its passage through the orifices 24 and avoids causing a sudden effort on the transom 14 and therefore avoids any brutal effort on the front of the mobile.
  • the ballast water may be distributed partly at the rear and partly towards the center of the mobile 10.
  • the means 20 for controlling the displacement of a volume of ballast water in the mobile 10 represented on the figure 2 performs this function by only passing part of the volume of ballast water through the opening 26. In fact, since the opening 26 is shifted above the folded plane 16, only the volume of water that reaches the opening 26 passes to the rear part of the mobile 10.
  • the size of said opening 26 may be modulated depending on the volume of water that is to be passed or the speed at which this volume of water
  • the guide rails 27, a screw, placed through the bore 30 and screwed into a thread allow the locking of the flap 28 and the modulation of the opening 26.
  • the pallets 34 represented on the figure 4 fulfill the obstacle function. Depending on the spacing between the pallets 34 and the width of said pallets 34, it is possible to manage the flow rate of the ballast water volume and thus the flow rate of the ballast water in the mobile. These pallets 34 can be distributed along the folded bottom 16 and then allow permanent braking of the ballast water during the acceleration and braking phases of the mobile 10.
  • a solution, represented on figures 5 is to slow the flow over the entire length of the mobile.
  • the flow of water is slowed, in a variable manner, differently from the case of the presence of the plates 22, whose function has been previously described.
  • the flow of water on the convex elements 36 makes it possible to reduce the speed gain during the acceleration and braking phases of the mobile 10.
  • the convex elements 36 create variations in the slope of the bottom. folded along the longitudinal axis and thus disturb the flow of the ballast water.
  • the figure 6 represents a solution whose presence allows the slowing of the water only at the ends of the mobile 10.
  • the ballast water accelerated longitudinally on the horizontal plane 40 during the braking and acceleration phases is slowed down only once arrived at the ends of the mobile, on the curved planes 42.
  • the curved planes 42 then deflect the flow of ballast water and avoid that the water comes into contact too abruptly with the rear tables 14.
