ECOLOGICALLY CONTROLLED SHIP'S HULL RECONDITIONER STATEMENT OF GOVERNMENT INTEREST The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of royalties thereon or therefor.
BACKGROUND OF THE INVENTION Generally, ships needing their hulls cleaned of excessive amounts of marine organisms are dry docked and sand blasted only when the cost of dry docking the vessel is partially justified when the ship must undergo a major overhaul or extensive structural modifications. As a result, the hulls are fouled continually slowing the ships speed and requiring a consequent greater fuel consumption. One attempt at remedying this undesirable situation calls for divers going over the side and scraping away the organisms with hand tools or small, hydraulic rotary brushes. This approach is only nominally effective for a large area work and is usually resorted to only when spot maintenance is called for. Aside from the fact that this method of hull cleaning is time consuming and of questionable effectiveness, safety considerations mandate that diver cleaning be performed only while the ship is in port. Obviously, the removed organisms additionally pollute the harbor and, for this reason, this approach is ruled out. Another contemporary hull cleaning method relies on mounting rotary brushes on tug-like boats and pulling the brushes along and under a ships hull as the tug moves along its length. Again, the hull cleaning attempt is only marginally effective and large areas, particularly on the bottom of the hull, usually are missed. Another attempt relies on holding a pair of motor driven rotary brushes against the hull by at least one line reaching from either side and beneath the keel. By merely pulling the brushes from one water line to the other, via the keel, a strip of marine fouling is removed. After cleaning one strip, the supporting lines are longitudinally moved a short distance to place the brushes in line with another fouled strip and the process is repeated. Unfortunately, a number of personnel are required to reposition this device and a complete hull cleaning operation is quite lengthy. Additionally, when this technique is employed in a harbor, removed organisms add pollutants. No quick reliable method exists for removing marine organisms from a ships hull which does not aggrevate pollution problems. Since 100 percent fouling from these organisms occurs in as little as 60 days, most ships are permanently fouled and cannot perform as designed. The greater fuel consumption used to achieve and maintain an acceptable cruising speed consequently creates more exhaust gas pollutants in our atmosphere. A need currently exists for a hull reconditioner not requiring expensive dry docking for allowing a periodic cleaning of hulls to reduce pollution in our environment.
SUMMARY OF THE INVENTION The invention is directed to providing an apparatus for permitting preventative maintenance and for reconditioning the -hull of the ship including a semisubmerged platform having a channel sized to accommodate the lateral area of a ship. On internal opposing sides of the channel, a plurality of hydraulic rams is displaced to bring the bristles of a plurality of cylindrically shaped brush elements in contact with the ships hull. Motor elements impart rotational motion and the bris tles scrape marine organisms from the hull as the ship passes by. An appropriate suction unit is carried in the near vicinity of the brushes and a fluidily connected filter unit screens the removed organisms from the drawn-off mixture to avoid pollution of the surrounding water.
It is a prime object of the invention to provide a hull reconditioner for removing drag-inducing marine foul- Another object of the invention is to provide a hull reconditioner introducing no pollutants in a marine environment.
Still another object is to provide a hull reconditioner having the capability to accommodate variously configured hulls over a wide range of sizes.
Still another object is to provide a portable hull cleaning device for removing marine organisms in the open ocean to avoid accidental pollution of a harbor.
A further object is to provide a hull reconditioner ensuring reduced fuel consumption and a lessening of air pollution.
These and other objects of the invention will become more readily apparent from the ensuing specifications when taken with the drawings.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. I is an isometric depiction of the invention.
FIG. 2 is a top view of the invention.
FIG. 3 isa schematical cross-sectional representation of the cylindrical brushes conforming to the hulls configuration.
FIG. 4 is a perspective showing of a modification of the invention.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings, the supporting vehicle forming an integral portion of the hull reconditioner is most suitably a concrete platform 10 provided with a longitudinally extending U-shaped channel 11. The depth and width of the U-shaped channel is adequate to accommodate the deep draft and wide beam of large oceangoing vessels and a sufficient number of ballasting chambers with an appropriate pumping and conduit network is provided to raise or lower the platform to receive the vessels. The overall configuration and manner of construction of the platform generally follows the construction scheme of a conventional dry dock. Optionally, a suitable power train is added to allow selfpropulsion from one location to another although suitable towing cleats and fenders are provided to lower the initial cost of the invention.
If the platfonn is fabricated from welded steel plates or other structurally equivalent materials, care must be taken that adequate safeguards be included to prevent or minimize corrosion. It logically follows that all the elements of the invention described below be noncorrosive or corrosion resistant to assure long life and reliability.
A pair of fenders l2 and 13 are mounted along the leading edge of platform's entrance for mutual protection of the vessel and the platform as the vessel enters the hull reconditioner. A keel cushion 14 covers the bottom of the channel entrance to guard against damcleats l6 and block and tackle arrangements permit a more precise guiding of the vessel should there be particularly fouled areas on the ships hull needing prolonged brushing or rebrushing.
Cleaning of the hull is performed by three sets of rotary brush combinations, bow- stern brush combinations 17 and 18, a keel brush combination l9, and sidehull combinations of brushes and 21. Each of the brush combination sets includes a plurality of cylindrically shaped, high-speed rotating brushes 17a, 18a, 19a, 20a or 21a respectively. The brushes have hard or soft nylon bristles to ensure long life and are modifiable to include wire bristles to remove heavy fouling or paint.
Rotary scrubbing action of the brushes bristles is imparted by appropriately connected watertight electric motors 17d or 18d. These motors preferably being high-speed, high-torque prime movers capable of being responsively controlled to scrub hulls having varying amounts of fouling.
As the ship enters the concrete platform, a shaft l7c or 18c is rotated and an gularly displaces the swing arms to put the brushes 17a and 18a in gontact with the bow portion of the ships hull. Electrically or mechanically coupled feelers 17a or 18a" are carried in each brushs close proximity and to monitor the pressure exerted by the brushes as they contact the hull. The exact electromechanical linkage of these feelers is well known and further elaboration on the exact configuration and interconnection is unnecessary at this point.
Following the bow-stern combination, a keel combination 19 is carried by a plurality of hydraulic rams 19b and extends along a sufficient lateral reach to cover the breadth of the hull. The rams are arranged in pairs journaled at opposite ends of individual ones of cylindrically shaped brushes 19a and vertically displace the brushes a distance governed by a suitably interconnected sensor 19a. Although not specifically depicted in the embodiment of FIGS. 1, 2 and 3, suction devices are included to draw-in the removed fouling in much the same manner as described with respect to the embodiment of FIG. 4. As each brush is being brought in forceful contact with the bottom of the ship's hull, a coaxially mounted motor 19a" rotates it and cleaning begins. The design of the hydraulic rams, sensors, and motors is consistent with contemporary, commercially available models and structural novelty is not alleged at this point. Although the rams are shown to extend from a protective compartment 10a housing a single hydraulic actuator 19 b, the entire combination alternately is completely exposed to facilitate maintenance.
The last two sets of brush combinations, the side- hull combinations 20 and 21, are mounted in the concrete platform in an opposed relationship. Each of these combinations is maintained as an integral unit in a laterally traversing enclosure 20b or 21b. A plurality of wheels riding in a lateral track provides vertical support for the enclosures and responsive reciprocal travel in the track is ensured by a pair of hydraulically actuated push rods 20b and 21b.
The push rods laterally position the enclosures in the close proximity of the ships hull an additional plurality of hydraulic rams 20c and 210 actuated by hydraulic actuators 20c and 21c laterally displaces the individually connected brushes 20a and 21a to forcefully abut the side of the ship when interconnected sensors 200" and 21a" so indicate. Similarly to the aforedescribed coaction, motors 20a and 21a rotate the brushes and clean the fouling from the hull as the ship bypasses the brush combinations. Attention should be drawn to the fact that the bottom ones of these hydraulic rams have a longer reach than do some of the upper ones to bring the rotating bristles in contact with rounded portions of the bulls as they merge with the flatter keel area.
An improved modification of the invention appears in FIG. 4 and additionally calls for inclusion of a suction mechanism 24 for drawing off removed fouling. The mechanism consists of properly oriented fairings and ducts carried adjacent the rotating brushes to draw off the removed fouling and to channel it, via appropriate ducts, to a suitable filter trap for screening out the fouling. A pair of control stations 25 optionally is provided in this embodiment to provide vantage points from which operating personnel have opportunity for a visual inspection of the hull cleaning process-and to adjust the rotating brushes accordingly. Following the rotating brushes, paint applicators, schematically shown by rollers 26, complete a hull reconditioning cycle by applying a coating of anti-fouling paint after the hull has been cleaned.
Obviously, many modifications and variations of the present invention are possible in the light of the above teachings, and, it is therefore understood that within the scope of the disclosed inventive concept, the invention may be practiced otherwise than specifically described.
