FR2805519A1 - Rapid pollution clearing device, for use in case of disaster, comprises pilot's cabin at prow, with bridge disconnected from superstructure to allow ramps to be installed - Google Patents

Abstract

A pilot's cabin (1) is located at the prow and the bridge is disconnected from the superstructure to allow ramps (4) to be installed for throwing the floating reservoirs (3) rolled about an axis stored in this location. The boat has one or more decantation holds (5) with valves (6) at different levels in the dividers which separate the holds, allowing the voluntary or automatic passage of liquids of different densities from one tank to the next. Suction pumps (8) placed to port and starboard depollute the water. As the vessel advances, more or less quickly, depending on the state of the sea, and funnels formed by vanes (14) allow a maximum concentration of pollution at the point of pumping. The suction heads (9) are protected by a grille and the flotation line is calculated so only the top part of the sea saturated with pollution is sucked in. Recirculating pumps eject water from the bottom of the hold into the sea while the suction pumps feed a floating chamber at the prow. Solid but flexible holding arms (14) form two large funnels with the vessel to concentrate the pollution into the suction heads. These arms are made of several detachable and articulated elements: one or more stands for a trapezoidal plate for recovering the waste, the central part of which is inflatable to maintain the flotation line. A system of attachments hold the elements together. The first element has a flap which pivots on a hinge fixed to the vessel's hull. These arms with variable geometry allow the boat to fold its flaps quickly and return to an aerodynamic shape. When the boat reaches the spillage, it can deploy its flaps at an angle of up to 90[deg] and can therefore be operated in any sea conditions short of storms.

This device has a first feature -The bridge <B>: </ B> at the bow the cabin of the captain and crew (1) at the rear a platform (2) to store the tanks (3) oil recovery. They are plastic or other and rollable. Ramps (4) maintain these tanks for safety and facilitate maneuvering.

- The hold includes: the slop tank (5). This one can be partitioned for the stability of the ship. Valves (6) located at different heights of the partition may or may not allow the exchange of liquids between the compartments of the tank; openings or closures are automatic, programmed or manual. The water remains at the bottom of the tank and the oil stagnates above.

- The rear of the hold is occupied by the engine room, the various suction pumps (8) located port and starboard clean up the water. The advance of the boat, more or less fast, according to the state of the calm or agitated sea, and the funnels formed by the arms-pincers, (14) allow a maximum concentration of fuel oil instead of pumping (9) pipes hoses connect the openings made in the hull to the suction heads (9) each mouthpiece flared, protected by a grid, supernatant with floats. The arrow waterline [> of the nozzle (9) is calculated so that only the upper part of the sea saturated with fuel oil is sucked up. The (or the) settling tank is responsible for separating the different densities of the liquids. pumps, (12) located at the bottom of the hold, push back, at the stern, the water to the sea; while one (or) pump (13) draws fuel oil from the surface of the tank, using a floating end connected to the body of the pump by a hose of adequate length, then a rigid pipe crosses the engine room to the stern. Another hose feeds the towed container intended for this purpose.

For these purposes one can use a (or) rotary displacement pump or more simply the helical system of the Archimedean screw.

- Connected to the hull, the pincers (14) are composed of several detachable elements.

the apron (18) of trapezoidal shape, made of reinforced plastic, or other suitable material is designed for the recovery of waste that floats. Its central surface (19) is inflatable, a valve is provided for this purpose a waterline (23) is calculated to obtain the best efficiency. Extra-steel springs (21) are the backbone of the system, both strong and flexible. The first apron of the pincer arm is attached to the hinged leaf of the hinge (26). The male element (24) of the hinge is fixed firmly to the hull of the ship, the hinge (25) is longer than the spacing of the two female elements of the leaf (27) its purpose is to facilitate the vertical movement of the arm of the pincer relative to the waterline of the ship. The end element of the arm-pincer is composed of an electric motor (28) which drives a cage propeller (15) which seems to me essential for the operation of the system. The cable 1) serves both the power supply of the motor (28) and safety. The core encloses the two well-insulated conductors and a very strong, tensile-resistant sheath. The bow capstan wraps or releases this cable at the will of the captain.

Cylinders and their hinged levers (10) on port and starboard have the force to move the jaw (14) away from or closer to the hull. The lever (10) can take the path defined by the angle (17) and the arm (14) the defined trajectory, from 0 to 90 by the angle (16) Device characterized by the fact that thanks to this funnel with variable geometry thus formed between the hull and pincer arms (14) the boat can quickly go to the disaster area by folding its wings (14) which follow the shape of the hull to port and starboard: the angle (16) is zero it becomes aerodynamic. Arriving in the disaster area, the boat spreads its wings (14) the angle (16) can vary from a few degrees to 90 as a result of which, the boat clearance is operational at all times, storm excluded. The speed of intervention is proportional to the intrinsic possibilities of the boat.

All these elements: the hinge, aprons whose number is proportionate to the importance of the ship and the propeller cage (15) can be connected to each other by strong bolts of special steels, self-lubricating washers and springs ( 21) provide flexibility and credibility. The funnel formed between the hull and these muscular and flexible arms to match the wave profile, allows the efficient recovery of pollutants whose density is lower than that of seawater.
