Definitions

  • the present invention relates to reducing level variations of water surface in conjunction with a water intake opening and, particularly, to reducing the influence of waves that have on influence on the water intake opening of a floating vessel or device.
  • the invention will be described by way of example with specific reference to oil col- lecting equipment, although it must be understood that the regulator of the invention can also be used in other connections.
  • the invention utilizes a float that floats to ⁇ gether with the water surface and regulates the shutter member by the effect of the level variations of water surface. This enables one to achieve a smooth stream of water from the water intake opening using relatively cost-effective and simple equipment.
  • the float uses two parts arranged one upon the other at a distance from each other, the slit between them forming a flow path to the water intake opening.
  • the float is ar ⁇ ranged to be buoyant in such a depth that just the up- per part thereof is partly above water level, a surface layer of certain thickness can be separated from the wavy water and introduced into the water intake open ⁇ ing.
  • This kind of structure is very advantageous, for example, in conjunction with an oil collector because in practice, the oil to be collected is concentrated specifically in the surface layer.
  • rotatable cylinders are used as parts of the float that are rotated in opposite direc- tions so that the water that comes into contact with the cylinder surfaces flows though the opening between the cylinders toward the flow-through opening.
  • a solu- tion of this kind makes the separation and recovery of the surface layer even more effective than before.
  • Fig. 1 illustrates a first preferred embodi ⁇ ment of the regulator of the invention
  • Figs. 1 - 4 illustrate the regulator of Fig. 1 in operation.
  • Fig. 1 illustrates the first preferred embodi ⁇ ment of the regulator 1 of the invention.
  • the regulator 1 is at- tached to an enclosure 2 that can be attached to the hull of a vessel.
  • the water flows through the regulator into the enclosure 2 via the open front wall thereof, and further through an opening 3 in the enclosure 2 into the vessel via the water intake open- ing disposed in the hull of the vessel. Therefore, for example, during oil spill response, it is possible to supply the oil-water mixture floating on the water sur ⁇ face to the oil collector arranged inside the hull of the vessel.
  • the regulator includes a float 4, which in the embodiments of the figures consists of two parts 5 and 6, which in this example both consist of cylinders.
  • Each cylinder can be one-piece, or alternatively con ⁇ sist of several "discs" connected to one another.
  • the cylinders 5 and 6 are arranged one upon the other along parallel axes.
  • the horizontal axes of rotation of the cylinders are mounted with bearings 7 on the end pieces 8 arranged at the opposite ends of the cylinders.
  • the end pieces 8 consist of plates that have been pivotally connected 9 to the enclosure 2. Due to the hinges 9, the cylinders 5 and 6 of the float 4 can move verti ⁇ cally with respect to the enclosure 2 as the water level varies.
  • the cylinders 5 and 6 and the end plates 8 define between them a flow channel through which the water can flow into the enclosure 2 via the nearly wholly open front wall thereof and further from the en ⁇ closure via the opening 3 into the water intake opening of the vessel .
  • the regulator 1 shown in Fig. 1 is designed to be used specifically for conveying water to the water intake opening of an oil collector mounted within the hull of a vessel .
  • the float truly consists of two parts, whereby the float 4 can be so dimensioned that it is floating in a desired depth and "skims" a layer of certain thickness from the water surface to be conveyed to the water intake opening.
  • the parts specifically consist of the cylinders 5 and 6 as shown in the figures, which can be rotated into opposite directions so that the water-oil mixture that comes into contact with them flows toward the wa ⁇ ter intake opening.
  • the float solely moves the shutter member of the regulator 1 it is possible to use a one-piece float that also in this case can consist of a rotatable cylinder.
  • Figs. 2 - 4 illustrate the regulator 1 of Fig. 1 in operation, whereby the enclosure 2 is shown sec ⁇ tioned.
  • the figures show the operation of the regulator as the water level varies by the effect of waves so that in the situation of Fig. 2, the regulator is dis ⁇ posed on a wave crest; in the situation of Fig. 3 in the middle depth; and in the situation of Fig. 4 on a wave trough.
  • the float 4 has been so dimensioned that dur ⁇ ing use the lower cylinder 6 remains underneath the wa- ter surface and about a fourth of the upper cylinder 5 is disposed underneath the water surface.
  • the water surface is depicted with a line 13.
  • shut ⁇ ter member 11 disposed between the upper cylinder 5 and the enclosure 2, consisting of a plate in this embodi ⁇ ment.
  • the aforementioned shutter member 11 moves ver ⁇ tically together with the end pieces.
  • the shutter member 11 is disposed in such a place that from underneath thereof, between the cylinders 5 and 6, water can flow into the enclosure 2 via an opening 14 and further via the opening 3 into the water intake opening.
  • the wave trough as shown in Fig.
  • the shutter member 11 has, however, moved down ⁇ ward to such an extent that its lower edge has reached the wall 12 arranged in the lower edge of the opening 14 of the enclosure. In that case, the shutter member 11 and the front edge 12 together shut the flow path. In this manner, backflow from the enclosure is pre ⁇ vented.
  • the shutter member should prevent at least this kind of backflow possibly occurring on the wave trough. Excessive stream of water on the wave crest can also impede the operation of the collector, but it is, however, not so harmful as the backflow. To provide a more uniform stream, it is pref ⁇ erable to manufacture the enclosure as shown in the figures so as to be as big as possible in capacity so that the amount of water will suffice also during that time when the shutter member 11 has shut the flow path to the water intake opening.
  • the regulator 1 includes an engine or engines that are used to rotate the cylinders 5 and 6 into op- posite directions during use. This has been illustrated by arrows in Figs. 2 - 4. Thus, water flows via the opening defined in the vertical direction by the cylin ⁇ ders toward the opening 14 of the enclosure 2.
  • the regulator 1 also includes scrapers 15 that are in con- tact with the surface of the cylinders, or at least very close to their surface, and thus due to the rotat ⁇ ing movement of the cylinders, the scrapers remove the dirt that stuck to the surface of the cylinders.
  • the regulator has been arranged in conjunction with a separate enclosure, from which water is introduced via the water intake opening of the ves ⁇ sel to the oil collecting equipment installed in the hull of the vessel.
  • the regulator of the in- vention can also be utilized in other connections, for example, so that there is no separate enclosure; in ⁇ stead the regulator has been arranged directly in con ⁇ junction with the water intake opening.
  • a water intake opening of a vessel or e.g. the water in- take opening of a self-floating oil combating device can come into question.

Abstract

L'invention concerne un régulateur qui permet de compenser des variations de niveau de la surface de l'eau, par rapport à une ouverture d'admission d'eau. Le régulateur de l'invention comprend un organe volet (11) qui peut se déplacer verticalement entre une position ouverte, dans laquelle l'organe volet (11) ouvre une trajectoire d'écoulement permettant le passage d'un flux d'eau, et une position fermée, dans laquelle l'organe volet (11) ferme ladite trajectoire. Le régulateur de l'invention comprend un flotteur (4) relié à l'organe volet (11), agencé avant l'organe volet (11) dans la direction de l'écoulement et d'une taille qui lui permet de flotter à une certaine profondeur et qui, au fur et à mesure que le niveau de l'eau (13) descend, déplace l'organe volet (11) vers la position fermée.
