Definitions

  • the present invention is directed to the problems associated with the cleaning of the cargo holds of ships and is a device for use in connection with that operation.
  • the present invention is intended to provide such animprovement.
  • invention is a device for cargo hold cleaning which comprises a sieve member surrounding an axis and having securing means disposed beyond the end (in the axial sense) of said sieve member, said securing means being operable from that side thereof which is axially nearer to said sieve member.
  • the sieve member of the device according to my invention surrounds an axis and may therefore be to a greater or lesser extent elongated in form.
  • it may be of symmetrical cross-section, for example cylindrical or of square or hexagonal cross-section, and its length in an axial direction may be greater or less than its maximum transverse dimension, that is its diameter in the case of a cylindrical sieve member.
  • the proportions of such a sieve member may vary between an essentially tubular form at one extreme and a more drum-like (that is, squat) shape at the other.
  • the shape of the sieve member allows it to present a larger sieving surface to the wash water than is normally possible using a flat strainer, whose dimensions are determined by those of the bilge well manhole. Because, in use, it may extend vertically from the bilge top, it is also less liable to uniform deposition of solid matter on its surface and therefore less readily choked by such matter.
  • the securing means is operable from its side which is nearer to the sieve member, then it is possible to mount the sieve member securely upon the deck of the hold without the operator having to enter the bilge or otherwise secure the device from below the deck.
  • the securing means may take a variety of forms. At its simplest, it may be one or more clamps or clips which engage the edge of the bilge access manhole to retain the device in position around said manhole. In another form, the securing means may be axially asymmetrical, having a maximum dimension transverse to the axis of the sieve member and a lesser dimension in the same plane (so that the securing means may pass through the bilge well manhole but seat against the underside thereof), and tightening means may be provided for moving the securing means axially towards and away from the sieve member.
  • the securing means When the securing means is of this type, the operating recuirements are best met, and the flow of wash water into the bilge is least impeded, if the securing means is a transverse member having at least two, but preferably more, projecting arms.
  • the securing means may be essentially at least three arms projecting from a central hub. Typically, it may be a star or spider having three to six arms.
  • the above-mentioned tightening means has the function of moving the securing means axially towards and away from the sieve member.
  • the sieve member may be held firmly against the bilge top, which is embraced by, and may be gripped between, the sieve member and the securing means.
  • the tightening means may usefully take the form of an elongated spindle, disposed alonr the axis of the sieve member and carrying means for locking the sieve member and securing means fixedly relative to each other.
  • the spindle may be threaded for at least a part of its length and the sieve member and/or securing means may itself be internally threaded or a nut may be provided to fix it relative to the spindle.
  • the securing means may be collapsible to allow it to pass readily through the bilge well manhole.
  • it may have projecting arms pivoted on a central hub.
  • the securing means comprises at least two fixed arms, disposed essentially radially relative to the axis of the sieve member, and at least two retractable arms, mounted so as to be movable between a retracted position of lesser radial extent and an extended position in which they are disposed essentially radially relative to the aforesaid axis and in which they are urged towards said fixed arms.
  • retractable arms In that extended position of the retractable arms, they are able to cooperate with the fixed arms to grip the adjacent decking and thereby hold the sieve member in position.
  • the sieve member may be sealed at its upper end by a solid or perforated lid.
  • the lid may be removable to allow visual or other access to the bilge well.
  • the dimensions of the device of my invention are largely determined by the location in which it is to be used. Bilge well manholes are designed to meet Lloyd's requirements and tend therefore to conform to a limited number of designs. Thus a limited range of devices according to my invention may satisfy most needs.
  • the sieve member may readily be exchanged for one of different dimensions or different perforation size, thereby significantly increasing the number of locations and situations in which the one device can be used.
  • the device according to my invention may be made of metal, for example of steel, and will thereby be suitable for use in a wide range of conditions.
  • the sieve member may be constructed in plastics material, for example in polypropylene or in glass-reinforced plastic.
  • the device shown in Fig. 1 is built around a threaded spindle 1, retained so as to be capable of rotation in a sleeve 2 mounted on a base plate 3, by means ofalocking pin 4 which cooperates with an annular groove 5 in the lower end of the spindle 1.
  • a squat cylindrical sieve member 6 is slidably located upon spindle 1.
  • the sieve member 6 incorporates radial rams 7 extending from a hub 8.
  • a lid 9, so sized as to be able to close the upper end of the sievenember 6, is also slidably located on the spindle 1.
  • a star plate 10 having six radial arms 11 extending from an.internally threaded hub 12, engages the threads of the spindle 1 between the base plate 3 and the sieve member 6.
  • the upper end of the spindle 1 is provided with a short extension, square in cross-section, by means of which the spindle may be rotated using a handle 130
  • Fig. 1 The position of the device in use is shown in Fig. 1 by the dotted-line representation of the bilge tank top 14 and the access manhole 15.
  • the spindle 1 already attached to the base plate 3 by means of the pin 4 and carrying the star plate 10
  • the star plate 10 is then held against rotation while the spindle 1 is rotated, using the handle 13, in such a direction that the star plate 10 rises until it firmly abuts the under side of the bilge tank top 14.
  • the spindle is thereby held riridly in place to receive the sieve member 6 and the lid 9.
  • the base plate 3 is dispensed with, the spindle 1 is secured to the star plate 10 and the hub 8 of the sieve member 6 is internally threaded and/or provided with a locking nut, so that the bilge tank top is positively gripped between the star plate 10 and sieve member 6.
  • a hose may be passed into the bilge through the sieve member 6 in order to admit water under pressure to agitate any sediment in the bilge or to allow access to enable a suetion pump to remove sediment or oil or other liquid from the bilge.
  • Fig. 2 shows a device 16 for pressurising, flushing or priming an associated bilge line.
  • the device 16 may be locked in position over a manhole using a star plate such as star plate 10.
  • the extensions 17 from the lower end of the device 16 may interlock with the arms 11 of such a star plate.
  • the device has two water inlets 18 and 19 and is also provided with a gauge 20, by means of which the pressure in the system may be monitored, and, associated with the gauge, a suitable pressure relief valve (not shown).
  • water from a static head and/or water supplied under pressure by a portable pump may be introduced into the device 16 and in turn into the associated bilge line.
  • a head of water may be provided using a water line from the deck above or water may be pumped in from the bilge on the other side of the ship.
  • water from the deck above may be suppled to supplement the pressure from such a portable pump.
  • a further way of providing a head of water is by using the sounding pipe which normally extends from the deck direct to each bilge for each hold.
  • the device comprises a squat sieve member 23, which may be cylindrical or of square or hexagonal cross-section when viewed from above, held in position by a securing means designated generally by the numeral 24.
  • the securing means is built about a vertical spindle 25, having threaded portions 25 a and 25 b and terminating at its upper end in a square-cross-section portion 25c.
  • the four fixed arms 27 rest upon a continuous, inwardly- directed flange 23a of the sieve member 23.
  • a winding handle 33 is engaged over the spindle portion 25c and is used to rotate the spindle 25 and thereby cause the threaded member 31 and rocker bracket 29 to move downwards along the threaded spindle portion 25a. This movement causes the arms 28 to swing in the direction of the arrows until they engage ;he underside of the decking 22 in the position shown in solid line in the drawings.
  • Pivotting of the rocker bracket 29 about the pivot 30 allows the device to compensate for local irregularities in the decking.
  • the decking 22 is gripped between the four fixed arms 28 and the two retractable arms 27 and the device is thereby held firmly in place.
  • a perforated lid 34 is now located around the spindle 25 within the top of the sieve member 23 and is locked in place by a knurled nut 35, which engages the threaded spindle portion 25b.
