Definitions

  • the present invention relates to an oil skimmer comprising at least one assembly of rotating brush plates with oil wiping means and a collection recept ⁇ acle for the oil wiped off.
  • the skimmer according to the invention is main ⁇ ly characterized in that the brush plate assembly, the oil wiping means and the collection receptacle as well as a drive machinery for the skimmer and hy ⁇ draulic pump and operating means are mounted in a central unit between two longitudinal floats, and that the central unit is arranged to be lifted and lowered in relation to the floats, so as to obtain an advantageous depth adjustment in each specific case, and to be displaced in the longitudinal direction in relation to the floats so as to trim the skimmer when the collection of oil is being carried out.
  • Desired vertical and horizontal trimming is preferably carried out by hydraulically operated cyl ⁇ inders.
  • the central unit can be lowered below the lower support surface of the floats, so that the skimmer is also able to move on land, the central unit being lowered so that the floats rise into the air, the floats are displaced onward, the central unit is lifted, etc.
  • a plate means is provided close to the brush plates so as to extend at least over a sub- stantial part of the upwardly directed portion of the path of the brush plates in order to prevent oil from falling off the brushes too early.
  • the oil skimmer according to the invention can be used in many different ways.
  • the skimmer can be advantage ⁇ ously connected to a mother vessel by one or more projecting booms attached to the sides of the mother vessel, and so its own oil booms can be arranged to extend obliquely forward from the forward end of the floats.
  • the skimmer can be towed, especially if it is relatively large, comprising several brush plate assemblies.
  • the propellers are preferably disposed in tunnel-like casings, including bottom plates, to protect them from ground touching in shallow waters with plenty of rocks.
  • the skimmer is preferably used independently by util ⁇ izing its own drive machinery with propellers or the like at the back, whereby booms of e.g. aluminium are attached to the forward end of the floats so as to extend obliquely forward and outward, and the oil is collected in bags which are dropped when filled up, and can then be picked up by a vessel following after.
  • booms of e.g. aluminium are attached to the forward end of the floats so as to extend obliquely forward and outward, and the oil is collected in bags which are dropped when filled up, and can then be picked up by a vessel following after.
  • the skimmer can also be anchored outside a con ⁇ taminated shore, whereby the booms are positioned against the shore, which can then be flushed clean, that is, the oil is flushed back into the water and then collected by the skimmer.
  • Figure 1 shows the skimmer in a perspective view seen obliquely from the back.
  • Figure 2 is a top view of the skimmer.
  • Figure 3 is a side view illustrating the posi ⁇ tion of the brush plates of the skimmer.
  • Figure 4 is a top view of the brush plates.
  • the general structure of the skimmer appears from Figures 1 and 2.
  • Oil-collecting brush plates, a motor pump, a drive machinery etc. of the skimmer are arranged in a unit 1 mounted between two longitudinal floats (pontoons) 2.
  • Two projecting booms 3 with bracings 4 extend from the unit 1 obliquely forward and guide the oil on the surface of water to the oil-collecting brushes, the structure and operation of which will be described more closely below with reference to Figures 3 and 4.
  • the unit 1 is provided at its corners with vertical guides 5 mounted slideably in vertical supports 6 mounted fixedly to the floats 2.
  • the vertical supports 6 are interconnected by means of at least one longitudinal rail 7 on both sides of the unit 1.
  • the fastening points of the support frame 6, 7 to the floats are indicated with 8.
  • the reference numeral 9 indicates two schematically shown hydraulic cylinders for lifting and lowering the central unit 1 in relation to the floats 2 to obtain an advantageous depth for the skimmer unit 1 itself in each specific case.
  • the reference numeral 10 indicates two hydraulic cylinders similarly shown schematically for trimming the skimmer unit 1, i.e. displacing it for ⁇ ward and backward in relation to the floats 2 so as to obtain an optimal trim when oil is being collected e.g. into an oil tank included in the skimmer.
  • the unit 1 is preferably arranged to move like a wheeled sledge along e.g. the rails 7.
  • the central unit 1 is thus lowered so that the floats 2 rise up into the air, whereafter the floats 2 are displaced onward and the central unit 1 is lifted, displaced onward or backward as required, etc.
  • the oil skimmer is also provided with a preferably diesel-operated drive machinery preferably disposed in the central unit 1 and comprising one or more propellers at the back.
  • the propellers are preferably mounted in tunnel-like casings 11 preferably also comprising bottom plates not shown in the figures.
  • the casings 11 protect the propellers during operation in shallow waters possibly containing plenty of rocks. Especial ⁇ ly when the skimmer is anchored e.g. close to a shore, the propellers create a suction flow from the front to the skimmer unit 1.
  • the reference numeral 12 indicates a deck plat ⁇ form in the vicinity of which the different operating devices of the skimmer, all known per ⁇ e and not shown in the figure, are positioned.
  • Figures 3 and 4 show the actual oil collecting apparatus, which is generally indicated with the reference numeral 20.
  • the oil is collected by means of an assembly of brush plates 21 with peripheral brush rings 22.
  • the brush plates 21 are preferably arranged to rotate anti-clockwise in Figure 3, so that the oil-containing water enters from the left (from the front) in the figure, and the oil in the brushes is first pressed under the surface of water and then lifted up and wiped off above by means of a comb-like member 23 into a trough or receptacle 24.
  • the individual brush plates 21 are axially spaced apart from each other so that the water is able to flow between the plates and fall down therebetween from the brushes when they are positioned above the surface of water.
  • a plate 25, 26 is provided to extend along the upwardly directed half of the path of the brush plates 21 close to the ends of the brush.
  • the lower half 25 of the plate may be fixed and preferably form one wall of the tank of the hydraulic system, and its upper half 26 is preferably detachable, so that the brush plates 21 can be lifted up if required.
  • the lower half 25 of the plate in particular but also the upper half 26 of the plate prevent the oil from fall ⁇ ing off the brushes too early and accumulating at the back of the brush unit 20.
  • the reference numeral 27 indicates an oil pump; 28 indicates an oil pump housing; 29 indicates a water pump; 30 indicates a water circulation/pump housing; and 31 indicates a pump housing door, which are main- ly intended for use in connection with fixed instal ⁇ lations.
  • the oil is preferably removed from the brush plates in the same way as described in WO 90/12157 by wiping means, whereafter the oil can be pumped away via a line connected to a coupling, such as a nearby vessel; alternatively, the oil is collected in oil bags or in a separate oil tank.
  • Water falling down from the brushes can flow away through openings provided in the side walls of the brush unit and preferably positioned essentially similarly as disclosed in WO 90/12157.

Abstract

L'invention décrit un nouveau système d'écumage de pétrole polyvalent et comprenant au moins un ensemble de brosses rotatives, pourvues de moyens d'écumage du pétrole, ainsi qu'un réservoir servant à recueillir le pétrole écumé. L'ensemble de brosses rotatives est monté dans un élément central (1) situé entre deux flotteurs (2) longitudinaux. L'élément central (1) peut être équilibré verticalement et horizontalement par rapport aux flotteurs (2).
