Definitions

  • This disclosure relates to a method and a device for preventing of fouling in general.
  • Fouling increases ship’s hull drag and decreases propeller performance, which increases energy consumption. It may also block seawater intakes and can cause the deterioration of paint systems. These all translate into reduced efficiency and higher expenditures (cost). Attempts to control the accumulation of these unwanted organisms have been made for centuries.
  • the inventors of the present invention have noted necessity for finding a solution to lightly clean, or‘groom’, commercially available coatings at specific frequencies to maintain the surfaces in a smooth and fouling free condition after hull is thoroughly cleaned or in case of a new ship and doing so during ships movement.
  • patent KR20160105629A uses a robot that cleans the ships hull with rotating bristles while using magnetic wheels to stay in contact with the ship. Also said invention collects all the cleaned material to a collecting tank. Said invention limits the usage of the robot into harbors or it can only be used while the ship is stationary. Similar robot and system is also described in patent CN105752290A.
  • patent KR20150114136A uses a cable driven robot that removes fouling under the ship. Described means in said patent limit the cleaning area to the bottom of the hull.
  • patent W02002096748A1 uses a cable driven mat that can clean both the sides and the bottom of the ship. Said device can only clean very small area at the time.
  • Above mentioned device is used as often as possible during ships cruising period in fully autonomous embodiment of this device the biofouling removal is performed continuously while all the environmental conditions are favorable.
  • the present invention also provides a device and method that is capable removing biofouling during ships movement at cruising speed and furthermore is capable to use ships movement to power itself.
  • the device uses waterflow over the ship’s hull during ships cruising to rotate itself around its longitudinal axis via fins attached to the device and by doing so rotate bristles or other grooming means attached to the device against the ship’s hull.
  • the present invention also provides a device that moves the above-mentioned grooming module longitudinally along the ship’s hull.
  • Said device comprising: an underwater section comprising of grooming modules; an above the waterline section comprising of means for moving the cable on both sides of the ship, linear guide means on both sides of the ship; a cable that connects both means for moving the cable and all the grooming modules.
  • Said devices means for moving the cable transfer the grooming modules back and forth along the ship’s hull along the linear guide means attached to the sides of the ship’s hull. Said device also adjusts the length of the connecting cable.
  • FIG. 1 shows a perspective view of a ship equipped with device for grooming a ship hull from fouling according to present invention
  • FIG. 2 shows a front view of a ship equipped with device according to present invention, where means for moving the cables with underwater grooming module are fixed to the linear guide means on both side of ship hull;
  • FIG. 3 shows a perspective view of the grooming module according to present invention
  • FIG. 4 shows a perspective view of two grooming modules connected together
  • FIG. 5 shows a cross-section of two grooming modules connected together and in detail universal joint between the grooming modules
  • FIG. 6 shows a perspective view of the device that moves the connecting cable, the device is attached to the linear guide means fixed in the upper part of the ship hull.
  • FIG. 7 shows a cross-section view of the grooming module while in contact with the sips hull to illustrate placement of fins and brushes.
  • FIG. 8 shows a cross-section view of two grooming modules connected together and in detail swivel joint between the grooming modules.
  • the ship cleaning device is constructed of several modules and it comprises an underwater grooming module(s) Fig.3 140, connecting cable Fig.1 130 and Fig.2 130, means for moving the cable
  • underwater before grooming module should be not taken as limitation because if the ship does not have load some underwater grooming modules can reach out in the water because the ship’s draft is decreased.
  • Each underwater grooming module 140 has a cylindrical shape and is capable to rotate around its longitudinal axis.
  • the adjacent grooming modules are connected to each other by connecting means.
  • grooming modules are connected to each other from ends via a universal joint 190 comprising of a pair of hinges oriented at 90 degrees to each other and connected by a cross shaft
  • underwater grooming modules are connected to each other but not influenced by each other’s motion so that they can move independently from each- other in said embodiment is used a swivel joint Fig 8 230 where one end of the grooming module has a ball swivel and the other end has a casing.
  • the underwater grooming modules are fitted with fins 160 that make the modules spin around its longitudinal axis, the fins are placed such a way that modules always spin in the same direction shown on the Fig 3 160 is one possible embodiment of these fins.
  • Also fitted on the grooming module are brushes or other means of grooming 200 that rotate with the grooming module and come in contact with the hull (not shown).
  • the brush lines are placed alternately with fins, i.e. brush line then fin, then again brush line etc.
  • fig 7 is shown in the five brush lines and five fins but the number brush lines or fins can be different depending of the design of grooming module.

  • the cross section of the fins is rectangular shape along the length of the fin or the cross section of the fins alternatively can be curved all along the length of the fin (see fig 3).
  • a hole 210 which houses the connecting cable (not shown in fig 3). Buoyancy keeps underwater grooming modules pressed against the ship’s hull. At the ends of each grooming module there is a wheel (roller) 180 that keeps the module at a certain distance above the ship’s hull. Said roller rotates independently from the grooming module when connecting cable is by means of moving the cable moving in the linear guide means.
  • Connecting cable connects both means for moving the cable located on upper part of the left and right side of the ship hull and passes underneath the keel of the ship’s hull. Also, the connecting cable runs through all the underwater grooming modules (see Fig 4 and Fig 5) while it goes around the ship’s hull.
  • the underwater grooming modules have an enclosed inner space or internal core that is an elongated toroidal shape that has a trough hole for the connecting cable.
  • the universal joints 190 have a trough hole 220 for the cable to pass through (see fig 5).
