Definitions

  • the present invention relates to a vessel whose hull has at least one opening necessary for the operation of one of its equipment, this opening being configured to be selectively closed or opened by a movable flap.
  • the shutter is materialized by a curtain of water.
  • KR101335255 we are dealing with a set of sliding elements which, when in the closed position, are arranged in the manner of a portion of camembert.
  • KR20120126875 describes a form of hull similar to that of a drop of water, in order to reduce the loss due to the bow thruster.
  • the closing device is similar to the diaphragm of a camera.
  • a sliding door device is described in particular in KR20120128823 , KR20100010353 and JPH01233199 .
  • JP2010120396 a door is described which, in the open position, protrudes out of the hull and pivots to plug the bow thruster tunnel.
  • KR20150127938 it is an inflatable balloon structure that obstructs said tunnel.
  • KR20130041622 a system is described that is similar to a plug valve.
  • a movable flap which is shaped to be moved between a first extreme position in which it leaves fully open the opening of the careen and is housed completely inside the latter and above said opening, and a second extreme position in which it partially or completely blocks said opening.
  • the displacement of the movable flap is composed of a translational movement and a rotational movement.
  • this component comprises an articulation axis allowing this rotation.
  • the flap is housed in an open box at its lower end, which extends inside the hull and which opens above said opening.
  • the aforementioned hinge axis extends opposite the free space defined by the opening.
  • the present invention aims to improve the devices discussed above, so as to provide a structure which the box which receives the flap has smaller dimensions.
  • the present invention relates to a ship whose hull has at least one opening necessary for the operation of one of its equipment, this opening being configured to be selectively closed or opened by a rigid movable flap, said opening being provided below of the water line, said flap being shaped to be moved between a first end position in which it leaves fully open said opening and is housed completely inside said hull and above said opening, and a second extreme position wherein it partially or totally blocks said opening, the displacement of said movable flap being composed of a translational movement and a rotational movement, a box open at its lower end being provided, in which said flap is housed in said first extreme position, said box opening above said opening, c characterized in that said flap has an axis of articulation allowing said rotational movement, this hinge axis being positioned so that, whatever the position of said flap between said first and second extreme positions, it is always positioned opposite the hull which borders said opening.
  • FIG. 1 we are dealing with a ship 1 whose hull 10 is partially represented. More specifically, we are interested in the portion of the hull located below the waterline F at which opens a tunnel 20 of generally horizontal axis of receiving equipment such as a bow thruster 2 , notably visible on Figures 2 to 4 .
  • this tunnel being able to receive another type of equipment.
  • the aforementioned tunnel is absent and the hull has a stabilizer cavity.
  • the tunnel 20 opens slightly back from the hull 10, at an opening 11 formed in the latter, as is well known.
  • the ship accommodates, inside the shell plating, a box 3 preferably metal.
  • This box 3 has a generally rectangular parallelepiped shape whose major axis extends vertically. It is delimited by vertical walls 30 and a top wall 31 provided with an orifice 310 not shown. All the walls of this box is attached, for example by welding, to the internal structural elements of the ship.
  • This box has the particularity of having an open bottom opening 32. As shown in the figures, this opening 32 is located vertically above the opening 11, and more particularly of its upper part.
  • An imperative of the invention is to deal with a flap 4 for closing the opening 11 which will allow it to be closed partially or completely, and by very significantly limiting the flow of water into the cavity blocked by flap 4.
  • this flap has the same shape and the same external shape as the hull, at the opening 11.
  • the flap 4 is rigid and, as shown in the appended figures, it comprises an upper element 40 intended to give rigidity to the shutter 4 and a lower element 41 which has the function of completely closing the shutter. opening 11 above.
  • the means which make it possible to print on the flap 4 a translational movement inside the casing 3 are for example constituted, as represented symbolically on FIG. figure 4 , by a pair of jacks 5 whose body is attached to the box 3, while the rod is integral, directly or indirectly, the flap 4.
  • the flap 4 In the position of maximum extension of the rod of these cylinders, then the flap 4 has a generally vertical orientation in which it extends partly outside the hull, as shown in FIG. figure 1 .
  • FIGS. figures 5 and 6 Preferred means that will enable it to undergo a partial rotational movement in order to close the opening 11 are more particularly represented in FIGS. figures 5 and 6 .
  • an articulated transverse panel 6 which has the particularity of having one of its longitudinal edges 60 hinged on the ribs 42 described above, about an axis XX 'which constitutes an axis of articulation of the flap 4.
  • the flap 4 can be oriented relative to the panel 6 around this axis X-X '.
  • a cylinder 7 whose body 70 is hinged to the panel 6 and the rod 71 on one of the frames 42 (preferably the central frame). If necessary, several jacks 7 working together can be used.
  • the panel 6 During the total duration of the movements of the flap 4, the panel 6 retains an identical orientation, here parallel or substantially parallel to the waterline of the ship.
  • the shape of the hull is optimized since the flap 4 has an external shape similar to this one.
  • this flap is very small so that little space is needed between the bow thruster and the hull.
  • the described device is simple, so that its maintenance is facilitated by access to the box 3 by its upper part located above the waterline.
  • the flap In the closed position, the flap can accept shocks and is not part of the integrity of the hull.
  • the flap 4 does not come out of the natural envelope of the hull, so that there is no interference with the maneuvering of the anchor of the ship, nor reduction of the hydrodynamic efficiency of the ship compared to an identical ship not equipped with such a component.
