Definitions

  • the present invention relates to a building intended to evolve on a surface of a plane or a watercourse, and to collect on board waste present in the vicinity of said surface.
  • Such buildings are commonly used to remove floating waste from port waters, such as floating objects or oil slicks.
  • the patent document WO 00/27694 discloses a building having means for retaining liquid waste placed on a path of a water channel inside the building.
  • a paddle wheel is placed on the water path upstream of the holding means to transfer liquid waste therein.
  • Two other paddle wheels are also used to evacuate water from the building.
  • US 4,372,054 describes a building having all the features of the preamble of claim 1.
  • One of the aims of the invention is to provide a building capable of collecting waste without using a specific pumping or picking device, device whose control would require actions additional to those necessary to maneuver the said building.
  • the invention thus guarantees automatic activation of the retention means by simple establishment of a circulation of water along the water flow channel which will then direct the various waste present at the entrance to the means of retention. water of said channel, the water outlet returning a sort of filtered water, since cleared of said waste.
  • the means of retention may for example be activated by the movement of the building alone, and therefore require no particular mechanism or control in the course of their operation. It will be enough for an operator to steer the building and direct it towards the waste that it wishes to collect, the building swallowing somehow said waste in the thread of its movement. The only skill necessary for the operator to control such cleaning operations will be an ability to maneuver such a vessel in its conditions of use, ie in a port, on a river, etc.
  • the retention means include liquid waste retention means disposed on a first path of said channel.
  • the liquid waste retention means will allow for example to collect hydrocarbon layers present in the vicinity of the surface of the plan or watercourse on which the building according to the invention is intended to evolve.
  • the building according to the invention may further include means for heating an upper surface of the water flow channel, intended to fluidify the hydrocarbons, which may be in the form of patties or semi-rigid pellets.
  • the liquid waste retention means include a holding tank intended to be traversed by the water flow channel when the building is in motion.
  • the building may also include means for regulating an internal temperature of the holding tank, which will maintain in a liquid state hydrocarbons contained in the tank, which will facilitate subsequent emptying of the tank, for example by pumping .
  • the outlet of the liquid waste retention means is intended to be obstructed by closure means when said liquid waste retention means are filled with liquid waste.
  • hydrocarbons are by nature lighter than water, they will gradually accumulate in the retention tank described above which will however allow the water, freed of these hydrocarbons, to escape through the bottom. said tank, which thus allows a collection and storage of liquid waste without interrupting the flow of water along the flow channel between the inlet and the outlet water.
  • This circulation will be interrupted only when the holding tank is full, that is to say when the building will no longer collect on board additional liquid waste. Such a circulation interruption is then performed by the closing means.
  • the closure means will preferably comprise a float having at least one surface capable of covering the orifice forming the outlet of the tank, which float is made of a material having a density greater than that of the liquid waste and lower than that of the 'water.
  • This embodiment of the closure means is advantageous in that it allows automatic closure of the holding tank when said tank is full. Indeed, since the float is heavier than the hydrocarbons held in the tank, it will gradually be pushed towards the hole in the bottom of the tank as it will fill with liquid waste. When the tank is full, the float will naturally be pressed against said orifice and thus plug the outlet of the tank.
  • the retention means include solid waste retention means arranged on a second path of said channel.
  • Retention means may include both liquid waste retention means and solid waste retention means. The fact that they are then placed on first and second paths makes it possible to ensure that the flow of water along one of the two paths will not be interrupted solely because of an interruption of the water circulation. along the other path.
  • the first and second paths of said channel may be merged between the inlet of the channel and an outlet of the means of solid waste retention.
  • Such an arrangement of the liquid waste retention means and solid waste retention means reduces the bulk of the building while minimizing the risk that untimely interruptions occur in the water flow paths. Indeed, it is mainly when the liquid waste retention means are filled with such waste that an interruption of water flow occurs, to avoid a discharge of this waste to the water outlet of the building.
  • the arrangement of the solid waste retention means upstream of the liquid waste retention means, the first and second divergent paths downstream of the solid waste retention means makes it possible to ensure that an interruption of the flow of water at through means of liquid waste retention will not significantly affect the operation of the solid waste retention means.
  • the solid waste retention means may be made in various ways, and may in particular include at least one grid disposed across the water flow channel.
  • the solid waste retention means will preferably include a first and a second grid projecting relative to each other and integral with each other so as to form an assembly, which assembly is movable relative to said building.
  • This preferred embodiment of the solid waste retention means allows efficient collection and storage of said waste, and further allows to easily discharge said waste in a container when the building will have to be disposed of.
  • a building as described above will further include a turbine for driving said moving vessel, which turbine will have an inlet disposed downstream of the outlet of the water flow channel and a outlet intended to produce a jet of water to the outside of said building, below the surface of the plan or stream.
  • This third aspect of the invention is advantageous in that, the turbine being placed in the extension of the water flow channel, said turbine can regulate the flow rate of water flow in said channel, and in particular accelerate this flow, which is particularly useful during a start-up phase during which, although the movement of the building is relatively slow, efficient collection of waste is ensured by a high flow rate printed by the turbine in the channel of water flow.
  • the outlet of the turbine will advantageously be provided with a deflector having an adjustable position, which position will determine a direction of the water jet produced by said turbine.
  • the deflector will allow to maneuver the building without requiring other means dedicated to this specific effect, such as an auxiliary rudder.
  • the water inlet and outlet can be made in the bow and stern of said hull, which will include a hollow portion delimiting the water flow channel.
  • a building as described above will be provided with at least two shells integral with one another and substantially parallel to each other, a distance separating said shells delimiting a width of the channel water flow.
  • Such a multihull structure gives the building greater stability and maneuverability, and allows for a simple way of producing the water flow channel, which is formed naturally between the hulls.
  • Such a building may further include a fairing connecting between them funds of said hulls, a distance separating said fairing from the surface of the plan or watercourse delimiting a depth of the flow channel.
  • the fairing makes it possible to isolate the water flow channel from any eddy coming from the underside of the building which could disturb the operation of the retention means.
  • This fairing may further be provided with rolling elements such as wheels to facilitate operations of movement of the building on the mainland.
  • the Fig. 1 schematically represents a building BAT according to a particular embodiment of the invention.
  • This building BAT is intended to evolve on a surface of a plan or a watercourse, and collect on board waste present on said surface.
  • the BAT building includes retention means (MRS, MRL) capable of capturing and holding waste, and to be activated by a movement of the building. These retention means (MRS, MRL) are shown in bold lines in the present figure.
  • the building BAT comprises in this embodiment two shells CQ1 and CQ2 integral with each other and substantially parallel to each other. These shells delimit between them a water flow channel intended to connect between them an inlet and a water outlet EO and SO when the BAT building is moving, the retention means (MRS, MRL) being arranged on at least one path of said channel.
  • the retention means MRS, MRL
  • Retention means include means for retaining liquid waste MRL disposed on a first path of said channel.
  • These liquid waste retention means MRL include a retention tank CUV intended to be traversed by the water flow channel when the building BAT is in motion.
  • the BAT building here includes HM heating means of an upper surface of the water flow channel, intended to fluidify liquid waste formed by hydrocarbons, which could be in the form of slabs or semi-liquid pellets.
  • HM heating means may for example emit EMW electromagnetic radiation, in the form of infra-red waves or microwaves, the amplitude and wavelength have been previously adjusted so as to ensure penetration of said radiation EMW on a predetermined depth, which will be for example between 5 and 15 centimeters.
  • the BAT building will also advantageously include means for regulating an internal temperature of the holding tank CUV, which have not been represented here in order not to unnecessarily clutter this Figure, which control means will maintain in a liquid state hydrocarbons contained in the tank CUV, to facilitate subsequent emptying of the tank, for example by pumping.
  • These regulation means may for example be constituted by electrical resistances integrated into the walls of the tank CUV, and intended to be supplied with an electric current when the internal temperature of the tank CUV will fall below a predetermined threshold value. .
  • the liquid waste retention means MRL here also include a funnel ENT intended to direct a flow of water to the retention tank CUV and thus to promote the creation of the first path of the water flow channel.
  • the retention means further include MRS solid waste retention means arranged upstream of the water flow channel relative to the MRL liquid waste retention means.
  • These solid waste retention means MRS include a first and a second grid GR1 and GR2, arranged across the water flow channel, projecting relative to each other and integral with each other so as to form a set (GR1, GR2), which assembly is made mobile with respect to said building by means of a pivot connection with two SUP supports integral with the first and second shells CQ1 and CQ2, which pivot connection allows a rotation of said assembly (GR1, GR2 ) about an axis of rotation A1.
  • the building BAT further includes a turbine TUR, controlled by a motor MOT, and intended to drive said building in motion, which turbine presents an inlet disposed downstream of the outlet SO of the water flow channel and an outlet for producing a jet of water to the outside of said building BAT, below the surface of the plane or stream.
  • a turbine TUR controlled by a motor MOT, and intended to drive said building in motion, which turbine presents an inlet disposed downstream of the outlet SO of the water flow channel and an outlet for producing a jet of water to the outside of said building BAT, below the surface of the plane or stream.
  • the Fig.2 schematically represents this building BAT, seen from its port side, in a first configuration of operation.
  • the elements of this building that have already been described above are provided with the same reference signs and will not be described again here.
  • This schematic view makes it possible to observe a deflector DEF which is provided with the output of the turbine controlled by the motor MOT, which deflector DEF has an adjustable position which determines a direction of the jet of water OJ produced by said turbine.
  • This schematic view also shows a CAR fairing connecting the bottoms of the two hulls of the BAT building.
  • the BAT building evolves here on the surface of a body of water, a level of which is represented by a line NE.
  • the deflector DEF is in the up position, so that the jet of water OJ produced by the turbine is directed towards the rear of the building BAT, which then moves forward at a speed Vbat.
  • the relative velocity of the building vis-à-vis the water body gives rise to a water flow channel interconnecting the water inlet EO and the outlet water SO.
  • the establishment of this water flow channel is further favored by the flow of water through the turbine, the flow rate of the water flow in this channel can thus be regulated by acting on MOT motor controls. .
  • the liquid waste retention means MRL are arranged on a first path TRAJ1 of the water flow channel, the solid waste retention means formed by the first and second grids GR1 and GR2 being arranged on a second path TRAJ2 of said channel .
  • the first and second grids GR1 and GR2 which form the solid waste retention means being arranged upstream of the water flow channel with respect to the liquid waste retention means MRL, the first and second paths TRAJ1 and TRAJ2 coincide. between the inlet EO of the water flow channel and an outlet of the solid waste retention means located here between the first GR1 grid and the ENT funnel included in the MRL liquid waste retention means.
  • An adjustable threshold may be arranged upstream of the first and second grids GR1 and GR2 so as to regulate the combined flow of the first and second paths TRAJ1 and TRAJ2 as a function of a depression of the building BAT, which depression could by example be caused by overloading the building.
  • any solid waste DS having a dimension greater than a gap existing between two adjacent bars of the first and second grids GR1 and GR2 is retained by said grids as the building moves.
  • the first and second grids GR1 and GR2 do not impede the passage of liquid elements, and thus filter the water swallowed by the water inlet EO only solid waste DS.
  • the water present at the outlet of the solid waste retention means may contain, in the vicinity of the surface, liquid waste DL, represented here by hatching in the vicinity of the water level NE, such as oil slicks such as this. is often the case in port waters.
  • This liquid waste DL will be oriented along the first path TRAJ1 by the funnel ENT to the inlet EL of the holding tank where they will accumulate on the surface, since their density is lower than that of the water which can , escape through the outlet of the tank to the outlet SO of the water flow channel.
  • the creation of the flow flowing along the first path TRAJ1 is furthermore favored in this embodiment by a Venturi effect generated by the particular shape of the holding tank, which here has a decreasing surface in the direction of the depth.
  • the second path TRAJ2 of the water flow channel will also allow water unstained by liquid waste, since taken at greater depth, to flow between the fairing CAR and the underside of the holding tank towards the outlet of water SO. This second path TRAJ2 will not be significantly disturbed if the first path TRAJ1 is interrupted.
  • the liquid waste retention means MRL include closure means for obstructing the holding tank when it is filled with DL liquid waste.
  • closure means are here constituted by a float FL, made of a material having a density greater than that of liquid waste DL and lower than that of water, so that it is by nature maintained in position just below a separation line between the liquid waste DL and the water contained together in the holding tank. This allows automatic closure of the holding tank when said tank is full. Indeed, the float FL will be progressively pushed towards the hole made in the bottom of the tank as it will be filled with DL liquid waste. When the tank is full, the float will naturally be pressed against said orifice and thus plug the outlet of the tank.
  • the Fig.3 illustrates such a state of affairs in the form of a second configuration, in which the first path TRAJ1 is interrupted because of a closure by the float FL of the orifice made in the bottom of the tank of the waste retention means MRL DL liquids.
  • a closing flap TF has also been actuated to obstruct the inlet EL of the holding tank.
  • the second path TRAJ2 is not significantly affected by the interruption of the first path TRAJ1, so that water continues to flow in the flow channel connecting the water inlet EO and the SO water outlet, the BAT building continuing to move at the Vbat speed.
  • the persistence of the existence of this channel obtained through the second path TRAJ2, allows the solid waste retention means to continue to operate, as shown by the presence of a new solid waste DS collected by the first and second grids GR1 and GR2.
  • the Fig.4 illustrates a third possible operating configuration of a BAT building according to the particular embodiment described above.
  • the deflector DEF which is provided with the output of the turbine controlled by MOT motor is in the low position, so that it interferes with the jet of water OJ produced by said turbine by deflecting it forward BAT building.
  • This has the effect of reversing the direction of the speed Vbat of said building BAT, and thus to move said building in reverse.
  • Such a faculty of displacement in reversing is particularly useful in situations where the BAT building has only a small margin of maneuver, such as in port facilities where available space is generally occupied as much as possible by ships at berth or berthing or departure.
  • the deflector DEF may also be constituted by an assembly of a port half-deflector and a starboard half-deflector, the latter not being shown in the present figure where only the port half-reflector is apparent, said The baffles are then controllable separately to bend the direction of the jet of water OJ produced by the turbine to port or starboard.
  • the deflector DEF is oriented so that the jet of water OJ produced by the turbine has a vertical direction.
  • the speed Vbat of the building BAT relative to the plane or watercourse will then be zero, once any effect of inertia dissipated, but the flow rate between the water inlet EO and the water outlet SO will be preserved and will keep activated the means of retention (GR1, GR2) of solid waste DS and the retention means MRL of solid waste DL, although the movement of the building BAT has been interrupted.
  • the Fig.5 illustrates a fourth possible operating configuration of a BAT building according to the particular embodiment described above.
  • the BAT building was docked to unload the various waste it collected on board.
  • the assembly constituted by the first and second grids GR1 and GR2 has been rotated about the axis A1 of the Pivot link linking said assembly (GR1, GR2) supports SUP, which pivot connection confers in this example to said set (GR1, GR2) its mobility relative to the building BAT.
  • the assembly constituted by the first and second grids GR1 and GR2 may be entirely removable.
  • the solid waste DS collected and stored by the solid waste retention means constituted by said first and second grids GR1 and GR2 are then dumped into a bin BEN, suspended in this example to a PAL hoist.
  • the liquid waste DL contained in the holding tank, the inlet and outlet of which have previously been closed respectively by the closing hatch TF and the float FL, will be extracted by means of a drain pipe TUY developing a ASP suction force.
  • unloading operations of the building BAT can also be carried out on the ground, the lower surface of the fairing CAR of the building BAT being provided with rolling elements, in this example a front wheel R1 and two rear wheels R2 and R3 of which only the port wheel is visible, to facilitate moving operations of the BAT building on the mainland.
  • rolling elements R1, R2 and R3 will also be very useful for loading said BAT building on a platform or a trailer for transport, for example by land, as well as for launching the building BAT, since it will then be enough to roll it along a strike, which avoids resorting to a crane.
