Definitions

  • This invention relates to the field of stopping leaks in vessels.
  • the present invention relates to preventing and sealing leaks in ships and boats.
  • the present invention also relates to methods of sealing leaks in vessels.
  • Boats and ships include a hull portion, a section of which typically lies below the water line. Any breach of the hull portion can result in a leak which must be dealt with as quickly as possible to minimise water entering the ship. If a leak is not sealed quickly enough, sinking can become a possibility.
  • the hull can be divided into a plurality of watertight sections which limit the spread of water throughout the hull.
  • a hull breach or leak may also be sealed from the inside of the vessel, however these methods require the actuation of force against the flow of incoming water, which can be considerable. Such methods also typically require a large amount of manpower and are prone to failure and/or crew injury caused by the constant pressure of incoming water.

  • Fig. 12 is an illustration of a side view of a clamp closing mechanism 300 for use with a clamp of the present invention.
  • Clamp closing mechanism 300 includes a handle portion connected to a first pair of elongate members 320, 322. Each of the first pair of elongate members 320, 322 are coupled to extruded planar portions 324, 326 extending from the first clamp segment. Each of the extruded planar portions 324, 326 are coupled via bolts 323, 325 to the first pair of elongate members 320, 322. The extruded portions 324, 326 comprise substantially planar portions adapted to receive a bolt.
  • the first pair of elongate members is further coupled to a second pair of elongate members 330, 332 via bolts 331, 329.
  • Extruded portions 334, 336 couple the second pair of elongate members 330, 332 via bolts 335, 333 to the second clamp segment.
  • the extruded portions 334, 336 comprise substantially planar portions adapted to receive a bolt.
  • each of the elongate members are formed metal, metal alloy, plastic or wood of suitable strength to withstand forces operating on the clamp during clamping and also during operation of the sealing device.
  • the bolts may be formed of any suitable material and may be screw threaded.
  • Alternative fixing means may be used to secure the individual components of the clamp closing means such as but not limited to locking pins.
  • the term vessel is taken to be any container.
  • the vessel is capable of holding a fluid, e.g. a liquid or a gas, such as air.
  • a vessel includes but is not limited to, ships, boats, submarines, road tankers, e.g. oil tankers, milk tankers, water tankers, and other vessels used to hold fluids such as water, petrol, foodstuffs, and gasses where leakage into or from the vessel may be an issue.
  • the device of the present invention when used in ships is not limited to use in the hull or below the waterline, but may be used at any point throughout the ship where a leak may occur, e.g. weather damage to an upper portion of the ship may be subject to water egress caused by high tides, high seas, large waves or precipitation, e.g. rain or snow.
  • the deformable portion comprises a layer of foam or similar material which is mouldable about the debris.
  • the deformable layer 30 may be selected to be of varying thickness depending on the size of the breach and the thickness of the vessel wall which can dictate the degree of debris resulting from the breach. In embodiments where the deformable layer 30 is detachable from the sealing device, a choice of deformable layers 30 may be kept at a convenient location within or near the vessel and added at the point of use to ensure the correct thickness is chosen.
  • any of the layers of the sealing member may be easily removed and replaced in isolation from other layers of the sealing member and the rest of the sealing device.
  • leak, breach and damage are used interchangeably and are to be understood to mean any damage of failure of a vessel wall which does or could lead to fluid leaking into or out of the vessel interior.
  • the sealing device may be assembled on site. Additionally, after use, the resilient member and/or the deformable member may be damaged and require replacement. Thus, the resilient member and/or the deformable member may be detachable from the sealing member.
  • the shape of the sealing member, deformable portion and resilient portions may be altered to be any shape that allows the sealing device to be used within any given hull portion.
  • hull compartments at the stern or bow may be of a shape different to those in the central sections of the hull.
  • the person skilled in the art would readily realise that the sealing member and associated sections could be made in a different shape to allow the sealing device to seal a breach in a less accessible area of the ship or vessel.
  • alternative means for locking the actuating means in place may be used without deviating from the scope of the present invention.
  • bolts, screws and the like may be used to lock the levers in a given position.
  • a modified clamp 400 is illustrated in Fig. 13 .
  • This embodiment is particularly effective in addressing a breach in a hull of a vessel in which the damage is so extensive that the T-shaped or P-shaped projections 26 within the interior of the hull are distorted.
  • a collar 401 is mounted upon the support member 18 and can slide along the support member.
  • the clamp body comprises a substantially U-shaped member 402 with a transverse bar 403 spanning the open ends of the body.
  • a universal coupling joint 404 connects the bar to the collar 401. This joint allows for a twisting movement of the collar relative to the clamp body which can compensate for a degree of converse twisting in the frame of the hull.
  • Two spring loaded clamping arms 405 are connected to the clamp body preferably opposite to the bar 403.
  • the surface of the arms facing the hull may be curved to assist in the rapid placement of the clamp arms over the T or P section of the hull.
  • the clamp as shown in Fig. 11 may be connected to the clamp body 402.
  • a similar universal joint may be used to connect the sealing member 12 to the actuating means 14 as shown in Fig. 14 .
  • the U-shaped clamp body is replaced with a U-shaped formation 450 on the rear surface of the sealing member and a projection is formed on the actuating means through which the universal coupling joint passes. This would provide greater flexibility and movement of the sealing member during placement thereby ensuring a tight seal against the hull.
  • FIG. 15-17 A further modification of the clamp is shown in Figs. 15-17 .
  • the clamp 500 comprises a rotational element in the form of a plate or disc 506 preferably between the collar 501 and the clamp.
  • the plate is rotatable mounted on the collar via a pin 507 and provides for greater flexibility and movement at the clamp.
  • the rotatable plate is illustrated as a thin disc but may have any shape and form to provide flexibility of movement and structural strength.
