Definitions

  • the invention relates to the field of cleaning water bodies such as in particular, but not exclusively, the water bodies of seaside resorts.
  • the invention relates to techniques for recovering waste floating on the surface of the water or at a shallow depth, and in particular macro-pollutants which are frequently encountered in swimming areas (pieces of plastic , various packaging ....), but also micro-waste.
  • the invention thus finds its application in particular in operations carried out to clean up the coastline, lakes or even port areas.
  • the floating pollutants which contaminate the water bodies of the beaches can thus be of very varied nature and size and appear in the form of waste of any kind or even in the form of hydrocarbons. Their accumulation in certain port or coastal areas is frequently reinforced by pleasure craft or commercial traffic, as well as, in some cases, by sea currents.
  • the two upper sides of the bow move apart by means of hydraulic cylinders, creating an opening 5 meters wide perpendicular to the longitudinal axis of the boat. Thanks to suitable ballasting, this opening of the bow allows water to enter the interior of the boat through a weir, the draft of which has a height of about ten centimeters. The water then enters the nozzle from the front of the boat and the propeller propels it backwards, at a flow rate of approximately 1 cubic meter per second. The advancement of the boat therefore allows pollutants to be drawn towards the weir. Floating trash is thus intercepted by a grid fitted with a lifting device. The grid lifting device, controlled by a hydraulic cylinder, rejects the detritus collected in a removable bucket.
  • This type of pollution control vessel has many drawbacks.
  • such a ship includes complex mechanical means making it possible to open its bow in order to allow reception of the waste.
  • These mechanical means allow a wide opening of the two sides of the bow so as to form a spout allowing the water to rush into the interior of the boat and to trap floating detritus on the surface thereof.
  • These means require regular maintenance and have a reliability inversely proportional to their complexity.
  • Such an opening of the bow makes it impossible to operate this vessel as soon as the sea is a little rough or has a swell even modest.
  • a catcher abatement comprising means for receiving pollutants located between its two hulls and moreover having means for bringing the pollutants to said reception means constituted by at least one ramp of fluid jets disposed in front of the reception means essentially perpendicular to the longitudinal axis of displacement of the catamaran, the jets being able to be used to create a current making it possible to propel the pollutants floating on the surface of the water towards said means for receiving the pollutants.
  • a catamaran has been described in French patent application No. 92 10023 in the name of the applicant.
  • the objective of the present invention is to propose a navigable abatement device which does not have the drawbacks of prior art ships.
  • one of the objectives of the present invention is to provide a depollution machine having great maneuverability and which can be brought very quickly to an area to be cleaned.
  • Another object of the invention is to provide such a machine that can be used by a single person.
  • Yet another objective of the invention and to provide such a pollution control device requiring no manual intervention on the collected waste.
  • a sea scooter that is to say a small vessel powered by hydrojet
  • a sea scooter can intervene quickly. It can collect macro-pollutants even at low speed and has great maneuverability. In addition, it can dock on the beaches, in order to allow the operator to carry out a manual collection of macro-pollutants present on the beaches themselves, in particular when these beaches are of small crack dimensions.
  • Such a device has, moreover, a reduced size allowing it to be taken on board a conventional ship and in particular on board a pollution control ship of the type described previously. It will also be noted that such a device has maximum visibility allowing, where appropriate, the operator to manually reach very large or relatively deeply submerged macro-pollutants.
  • the very design of this sea scooter guarantees absolute safety vis-à-vis swimmers, in particular thanks to its turbine propulsion.
  • the false bow makes it possible in particular to prevent macro-pollutants from getting caught between the hull of the scooter and the pollutant receiving frames.
  • said means for receiving and storing pollutants are provided with at least one ramp of fluid jets disposed essentially perpendicular to the longitudinal axis of movement of said scooter, said jets being able to be used to create a current making it possible to propel pollutants floating on the surface of the water towards said receiving and storage means.
  • These jets also prevent the return of macro-pollutants in the aquatic environment, when the speed of the scooter is zero.
  • jets of fluids also known under the English term of "jetting” thus allows the scooters scooter to operate in the most remote areas of water bodies and thus rid them of their pollutants.
  • said lifting device has means making it possible, in the transit position, to retract said means for receiving and storing pollutants along the hull of said scooter.
  • said scooter has a small footprint and can be brought into areas of difficult access.
  • such a "retraction" of the pollutant collection means makes it possible to maintain the hydrodynamics and the stability of the scooter and thereby its ability to intervene quickly.
  • the machine comprises on the one hand dodging means allowing, in the collection position, said means for receiving and storing pollutants to retract in the event of a collision with an obstacle, and on the other hand means reminder allowing said means for receiving and storing pollutants to return to the collection position, once the obstacle has been avoided.
  • dodging means allowing, in the collection position, said means for receiving and storing pollutants to retract in the event of a collision with an obstacle
  • reminder allowing said means for receiving and storing pollutants to return to the collection position, once the obstacle has been avoided.
  • each of said frames being provided with a pollutant recovery net.
  • the use of such nets has the advantage of offering great flexibility of use. In particular, these nets fold easily against the scooter in the transit position and can even be brought back to the scooter in the event of light loading.
  • said lifting device includes a horizontal rotary axis connecting together said frames installed on either side of the hull of said scooter, said horizontal rotary axis allowing said lifting device to bring said means for receiving and storing pollutants in said first pollutant collection position and in said second transit position.
  • a horizontal axis can thus be installed in particular at the front part of the scooter, essentially transversely to the direction of movement of the latter, so as to support the distribution of the means for receiving and storing macro-pollutants on each side from the hull of the scooter.
  • each of said frames is secured to said horizontal rotary axis by a lateral folding axis allowing said frame to be retracted against the hull of said scooter, when said receiving and storage means are in the transit position.
  • said dodging means mentioned above consist firstly of a vertical dodging axis connecting each of said frames to said rotary horizontal axis, and said return means are constituted by a spring returning said retracted frames to the collection position.
  • said fluid jets are inclined relative to the vertical so as to facilitate the creation of the current making it possible to propel said pollutants towards said receiving and storage means.
  • means making it possible to vary the inclination and / or the force of said jets of fluid are provided.
  • it is possible to create a more or less strong current directed towards the reception means and making it possible to cause floating pollution towards them.
  • the fluid distributed by the jetting ramp is chosen from the group consisting of water, air and dispersing products.
  • the use of dispersing products makes it possible to recover the floating pollution constituted by hydrocarbons.
  • the scooter according to the invention can therefore also be used in ports or in areas in which ships have degassed.
  • said device according to the invention is preferably provided with at least one handle secured to said rotary horizontal axis making it possible to place said device alternately in said position. collection and in said transit position.
  • the scooter used has modifications to the fairing or to the structure aimed at improving the ergonomics of the cockpit, in particular with regard to protection against spray and the comfort of the seat.
  • Such modifications may consist of replacing the saddle with a more comfortable seat or raising the freeboards.
  • said frames are each provided with a curved piece, said curved pieces forming, in the collection position, said false bow.
  • the invention relates not only to the depollution scooter described here, but also to the lifting device as such designed for the production thereof.
  • a lifting device can be used for another type of navigable device than a sea scooter.
  • the pollutants are transported to the receiving means, preferably comprising nets.
  • the means for receiving pollutants can be lifted out of the water and brought back against the hull of the scooter. The contents of the nets can then be brought to the quay and discharged to a waste treatment plant.
  • the depollution vessel of the invention is in the form of a scooter 2 and can be used to clean water bodies, such as in particular the water bodies of seaside resorts and more particularly beaches , in order to rid them of their surface pollution in the form of various objects.
  • This scooter has a length of about 3 meters, a width of about 1.5 meters and a very shallow draft allowing it in particular to dock on the beaches. Its transit speed of around 10 knots makes it likely to travel from one pollution point to another without wasting time. Its propulsion by turbine allows it to evolve safely even in bathing areas.
  • this scooter 2 is equipped with means enabling it to collect floating waste on the surface of the water and more particularly macro-pollutants in the form of various objects, such as bottles, plastic materials. , etc.
  • These means are constituted on the one hand by means of reception and storage 1 of the pollutants installed on either side of the shell 3 of the scooter 2 and on the other hand of a lifting device 4 of these reception means and storage 1.
  • the lifting device 4 can be easily manipulated by the operator driving the scooter using handles 16 in order to alternately pass the reception and storage means 1 into a collection position in which these are deployed so as to be at least partially submerged and in a transit position in which the means of recovery and storage 1 of the pollutants are raised out of the water.
  • the means for receiving the storage 1 of the pollutants are constituted by two frames 7 provided with nets 8.
  • the frames 7 have a sufficient dimension so as to show a part submerged at about 50 cm in collection position.
  • These nets 8 also have the advantage of constituting a light structure which can float according to the currents while trapping macro-pollutants.
  • the sea scooter thus equipped constitutes a pollution control device of very great maneuverability which can have a very high intervention speed compared to conventional pollution control vessels.
  • its structure allows it to access areas normally prohibited for depolluting vessels of the state of the art because of their large size, such as bodies of water in very narrow coves or maritime areas with rocks. or reefs.
  • reception and storage means 1 of the pollutants are shown.
  • these reception and storage means 1 each consist of a metal frame 7 having two compartments 7a, 7b each connected to a net 8.
  • the reception and storage means 1 of the pollution control device are shown in the port collection position and in the starboard transit position. Note however that, according to the embodiment described here, the reception and storage means 1 located on port and starboard are necessarily in the same position, collection or transit. However, according to other embodiments, means may be provided for placing the reception and storage means in a position to port independent of their position to starboard.
  • the frames 7 are oriented so that the compartments 7a and 7b receive the macro-pollutants at a speed equal to the speed of movement of the scooter . These macro-pollutants are stored in the nets 8.
  • the frames 7 to port and to starboard are brought against the hull 3 of the scooter 2 thanks to the lifting means actuated with the handles 16.
  • the nets 8 can be brought back to the scooter.
  • ropes 17 can be connected to the frames 7 so as to bring the recovery and storage means 1 against the shell 3.
  • the lifting device comprises a rotary horizontal axis 9 provided with two uprights 18 at the end of which are fixed handles 16.

  • the ropes 18 can be maneuvered to bring the storage and reception means 1 into the transit position.
  • the scooter has hydrodynamics and stability allowing it to move quickly and in particular to weave between obstacles.
  • the field of action of such a pollution control device is very wide.
  • the means for receiving and storing the pollutants are shown in front view (left part of FIG. 3) and in rear view (right part of FIG. 3).
  • these receiving and storage means have a frame 7 (and a net, not shown).
  • the frame 7 has an essentially quadrangular section and a length of less than one meter.
  • the frame 7 In the collection position, the frame 7 is immersed up to the dotted line 19 representing the water level of the zone to be decontaminated.
  • a non-return valve 5 is mounted inside the frame 7 so as to allow the introduction of pollutants into the frame 7 towards the recovery nets 8, when the speed of the scooter is positive or zero.
  • This non-return valve prevents the evacuation of pollutants trapped in the nets 8 when the speed of the scooter 2 is negative, that is to say when it reverses.
  • the non-return valve 5 of the frame 7 is shown in the closed position, so as to prevent the recovered macropollutants from being released.
  • a net, not shown, fixed between the lower part of the non-return valve 5 and the bottom of the frame 7 prevents recovered pollutants from being released when the non-return valve 5 is in the closed position. This net folds behind a grid 20 located at the front of the frame 7 when the non-return valve 5 is in the open position.
  • the frame 7 is moreover provided in its upper part with a jetting ramp 6 allowing the formation of several water jets 15.
  • the jets 15 make it possible to create a current of water replacing the current caused by the movement of the scooter 2 when the speed thereof is zero.
  • This artificial current on the one hand prevents the exit of macro-pollutants recovered from the nets 8 while promoting the routing of macro-pollutants to the nets 8, when the scooter is at a standstill.
  • the depollution scooter can therefore be used when it is moving, but also in areas where such movement is not possible.
