Abstract

Collector for floating oily substances with multifunctional flexible capturing spatula. The present utility model relates to a collecting vessel constituted by a floating chamber (1) formed by two broadsides (6), a bottom (7), a bow wall (8), a stern wall (9) and a deck cover (10), the function of which is to capture and condition inside, for subsequent discharge in suitable locations, floating oiling substances spilled onto liquid surfaces. International patent classification B63B35/32 (2006.1), E02B15/04 (2006.01). The oily substances are captured by laminar skimming by means of a multifunctional flexible capturing spatula (3) mounted on the bow of the vessel, inclined forwards and bent by a bending accessory (19) when the vessel moves forward, in a straight line, above a critical speed, the spatula being positioned under the liquid surface and separating when moved the contaminated peripheric layer, generating a reverse aqueous stream that enters the inside of the chamber by an intake path (4) that is created in the mouth of the collector (2), dragging the emulsified oily substances floating in the way, conditioning them on an aqueous ballast (5) until they are discharged by already available prior art equipment, while the aqueous portion of the dragging stream is integrated into the ballast and flows out through an exhaust (12) arranged in the stern of the vessel and which opens and closes according to the movement of the vessel and discharges outside an aqueous volume which is equivalent to that of the emulsion. Once the collecting operation is finished, the flexible spatula, after having fulfilled the multiple functions of layering, generating the dragging stream and capturing the oily substances, returns to the initial position, sealing the chamber and optimising navigation hydrodynamics.

Description

^" OIL COLLECTOR! FLOATING DIFFERENCES WITH MULTIFUNCTIONAL FLEXIBLE PICKUP ^*

[001] The present utility model refers to a collection vessel that has the function of capturing and storing inside it, for later evacuation in appropriate places, floating oils poured into the liquid surfaces.

International Patent Classification: B63B35 / 32 (2006.01); E02B15 / 04 (2006.01).

[003] The essential technical feature of the model to be protected is the instrument and the process for capturing supernatant oils, which is carried out by laminar scraping by the action of a multifunctional flexible take-up spatula mounted on the bow of the ship, tilted forward. .

[004] The flexibility; and the forward inclination of the take-up spatula, is the inventive, not evident novelty of the utility model described, essentially distinguishing it from similar collectors found in the state of the art: "FLOATING OIL COLLECTOR" (BR 10 2012 006322 0) and "FOLDING FLOATING OIL COLLECTOR (BR 20 2012 012544 2), in which the respective take-up spatulas are fixed and inclined to the interior of the nave.

The flexing and forward inclination of the take-up spatula, which is an essential feature to be protected, makes it possible to add to the trowel, in addition to the fixed trowels, the multiple drag-stratification functions of oils; sealing and opening of the collector internal space and optimizing navigation hydrodynamics, implemented relevant functional advance with economic advantages that support its industrial applicability.

The laminar scrape that collects the supernatant oils is effective when pushing the pickup spatula the functional impulse, which consists of a rectilinear frontal displacement. above a critical speed compatible with the dimensions of the equipment and the specifications of the harness, propelled by accessory propulsion sources. When subjected to Functional Impulse the pickup spatula is flexed forward by flexor fittings found in the state of the art, opening the intake pathway contained in the mouth of the collector and, with displacement, stratifying the peripheral layer of the liquid surface. front of the ship, generating a reverse aqueous flow that penetrates into the collector dragging the oils that float along the path.

The oils carried by the drag stream are cast onto an internal aqueous ballast where the oils, having lower density, clump together, gradually replacing the aqueous content of the ballast from top to bottom with a packaging column. which may occupy up to one third of the ballast volume, being available for evacuation at appropriate locations by state-of-the-art equipment,

The aqueous portion of the drag stream, thrown into the inner span, integrates with the aqueous ballast and exits externally through the exhaust system installed at the lower end of the stern wall, which is propelled by the internal flow of the flow. which is established in the lower layer of the ballast as a result of the functional displacement and closes when the forward displacement of the ship is slowed or interrupted.

Precisely dimensioned the inlet path with the flow path the aqueous volume that exits abroad will correspond to the volume of the emulsion released into the internal space; maintaining during operation the ballast level oscillating close to the pre-established operating level.

[011] The collection and conditioning of oils are automatically carried out, solely due to the forward displacement and flexion of the pickup, making possible by the formatting and arrangement of the structural components of the equipment; regardless of suction or absorption accessories.

[012] The functional thrust of the ship can be propelled by self propulsion; pushers or drag. [013] Coleior's structural technical specifications, which are necessary and characteristic, are graphically represented in the accompanying drawings and the present report; figure 1; 2; 3 and 4; included for demonstrative purposes only, without limiting the scope of patent protection and without observing proportions, quotations or scales, highlighting the structural components of the equipment with numerical references, Figure 1 being a perspective view of the collecting vessel; Figure 2 is a median longitudinal schematic section; Figure 3 is a median cross-sectional schematic view; and Figure 4 is an operational diagram showing the collection function.

[014] The structure of the collecting vessel consists essentially of a floating chamber (1), hollow at the rear end, with the front of the bow presenting an antechamber which constitutes the collector's mouth (2) housing a multifunctional flexible take-up spatula (3) Consistent with a forward-facing upwardly inclined ramp-up projecting from bottom to top of the water slide, installed at the upper end of the bow, where it articulates by opening and closing an intake neck (4).

[015] The floating chamber constitutes the hull of the coietadora nave, designed with dimensions and proportions compatible with the volume of the collection; the composition and viscosity of the oils to be captured and the water environment where it will act; accordance with the technical standards of shipbuilding.

[016] The ship's hull operates partially submerged by floating at a pre-established operating level, indicated by the dashed line "AA", stabilized by an aqueous ballast (5) composed of two sides (6); bottom (7); bow wall (8); stern wall (9) and deck cover (10), made of materials inert to the oils, with hardness and resistance necessary for the performance of the collecting function, which are interconnected, formatting the internal span (11) of the collector, communicated with the net mass through an exhaust neck {12} installed at the lower end of the stern wall, regulated by a flow shutter (13), provided with a lock (14) to lock the shutter to the end of the collecting operation. [017] The hull structure is double plated to preserve the net load in case of collision; the spacing between the double side and bottom plating being precisely sized to constitute the buoyancy system (15) of the nave.

[018] At the rear edge of the sides, tension sleeves (16) are attached to receive the functional thrust when pushed by pushers.

[019] When the functional thrust is propelled by self-propulsion or drag the ship's structure will suit the applied form of ions.

[020] The deck cover opens the manhole door (17) for access and services on the inside and installs for the transfer of coiled oils; ship services; fire fighting and navigational control, found in the state of the art and, optionally, equipment for launching and retracting containment barriers.

[021] The collector's mouth, formed at the front of the inner span, is constituted by a bottomless antechamber, open at the front, flanked by side extensions, covered by a shoulder of the deck, housing at the rear face the multifunctional flexible pickup spatula interposed between the antechamber and the collector's internal space.

[022] The forward-tilting, multifunctional flexible pick-up spatula hinges on a hinge base (18) fixed to the upper end of the bow wall, where the spatula flexes by opening and closing the communication path between the inner span and the collector's mouth.

[023] The flexing of the take-up spatula is driven by an accessory flexor system (19) consisting of hydraulic plungers installed on the ship's deck, either manually or computer controlled, found in the state of the art.

[024] At the opposite end of the hinge base, inclined into the interior of the void is installed, the internal reflux retaining spatula (20), provided with a float (21) which floats flush with the oil layer the internal ballast is supernatural, following its oscillations, flexing the retaining spatula to contain the reflux of the captured oils. In Figure 3 the oil column (22) overlying the aqueous ballast and the free edge (23), the space between the oil column and the deck cover, stand out.

[026] The multifunctional flexible pickup spatula, varying its degree of inclination, is positioned in two functional stages: sealing and navigation stage and stratification and pickup stage.

[027] At the sealing and navigational stage, as shown in Figure 2, the pickup spatula collides with the bonnet bulkhead (24), obtains the intake neck, frontally seals the inner span, and is positioned therein. The inclination of the bow wall optimizes the hydrodynamics of the navigation, allowing the craft to sail with great distances to meet the spill site and return to base.

[028] At the stratification and uptake stage, as shown in Figure 4, the uptake spatula inflates below the peripheral layer where the oiliness fluctuates to, with displacement, generate and stratify the drag flow, calibrating the flow at oil spot specifications, opening the admission path, enabling the emulsion penetration in the internal space of the ship.

[029] The flexion of the pickup spatula, sloping below the contaminated surface, has as its scope: to annul the frontal shock with the drag flow, impacting on the fixed pickup spatulas; minimize the prior thrust required to establish drag flow and decrease critical operating speed, considerably reducing the driving expense of the collecting operation.

[030] A large set of inclined transverse bulkheads constituting a hydrofoil system (25) with the function of shaping the hydrofoil (25) in the large and medium-sized collectors below the operating level, keeping a regular distance from the bottom of the hull. longitudinal displacement of the internal liquid mass, increasing the stability of the nave, and assisting in the decantation of the aqueous portion of the emulsion that dissociates from the longitudinally flowing oils on the ballast surface, directing to the extractor the aqueous flow of flow that forms in the lower horns. of the ballast. [031] Optionally the pickup flexor system can be equipped with cyber sensors and instruments, found in the state of the art, to automatically adjust, at the stratification and pickup stage, the degree of spatula tilt, making it oscillate accordingly. with the ripples of the nautical environment and the grease spot specifications to be removed.
