Definitions

  • the present invention relates to a method of cleaning the immersed parts of a boat that can be implemented without having to take the boat out of the water.
  • the invention also relates to a cleaning device for carrying out this method.
  • Cleaning the hull is usually done using mechanical means, such as brushes, tools or a jet of water under pressure to brush, scrape or strip the hull.
  • mechanical means such as brushes, tools or a jet of water under pressure to brush, scrape or strip the hull.
  • the boat must be out of the water.
  • the cleaning device comprises a rotating brush powered by a motor and disposed under a hood.
  • a device makes it possible to send air jets inside the hood in order to reduce the loss of engine power that would normally occur if the brush turned in water. However this cleaning device does not use jets of water.
  • the rinsing device comprises means for forming high-pressure water jets, mounted under a cover filled with air, in order to isolate said jets of water from the surrounding water.
  • this device does not provide to send gas jets under low pressure around these jets of rinsing water.
  • the two aforementioned devices provided with a cover, must therefore be applied against the shell to be cleaned, which limits the surface that can be cleaned at each passage of the device.
  • this apparatus comprises a high speed water generation nozzle, surrounded by an annular orifice through which air is ejected.
  • a cleaning device operating under water comprising, on the one hand, means for generating a water jet under pressure through a tube and, on the other hand, means for ejecting a jet of water under high pressure, through an annular passage surrounding said tube.
  • the jet of water under high pressure passes inside a cylinder whose walls are formed of a layer of air but which nevertheless contains water.
  • the water jet must therefore cross a high density water zone to reach the hull, which significantly reduces its effectiveness.
  • the present invention as described by the features of the independent claims 1, 2 and 10 is intended to develop a device and a method for cleaning the immersed parts of a boat, making it possible to use an ejection nozzle of a conventional high pressure cleaning fluid, which without the invention would be rendered inoperative by the water around the boat to clean or at least would be less effective.
  • the invention also aims to clean a large area of the hull at each passage of the device and thus reduce the total duration of cleaning, while performing a good quality cleaning and without taking the boat out of the water.
  • the invention relates to a device for cleaning the parts of a boat which are immersed in water, of the type comprising at least one cleaning unit which comprises first means for generating a jet of cleaning fluid under high pressure and second means for generating gas jets.
  • said first generation means make it possible to produce a jet of cleaning fluid in the form of a fluid blade and in that said second means comprise a ramp provided with a series of nozzles, connected to a nozzle. a booster or a gas supply, this ramp for generating low pressure gas jets, defining a space in which the density is significantly reduced relative to that of the surrounding water, such as a space free of or substantially free of water, around said cleaning fluid blade, this space extending over the entire length of said cleaning fluid blade, from said first generating means to the surface to be cleaned said submerged portions, said ramp being disposed under said first generating means, so that its longitudinal axis extends substantially in the same vertical plane as the one passing through the ejection axis of said cleaning fluid blade, the latter extending substantially vertically inside said space free - or substantially free - of water.
  • the fluid blade under high pressure which opens into this space, does not lose energy to repel the water in which the boat bathes.
  • Such a device allows for a correct cleaning of the shell while placing the cleaning unit about 5 to 30 cm from the hull. It thus becomes possible to clean a large surface of the shell in a single passage of the device.
  • the invention also relates to a method of cleaning the parts of a boat which are immersed in water, by simultaneous projection of a jet of high pressure cleaning fluid, on said immersed parts and gas jets.
  • the fluid is water or hot or cold water vapor and the gas is air.
  • this method can be implemented using the aforementioned device.
  • the device according to the invention comprises at least one cleaning unit 1 such as that shown in Figure 1, for cleaning the immersed parts 2 of a boat.
  • immersed parts of a boat refers not only the hull but also the keel, the saffron, the propeller and the propeller shaft.
  • submerged parts are schematized by the hull of the boat.
  • the cleaning unit 1 may be of known type. It comprises means 10 for generating a jet of cleaning fluid under high pressure. These means are for example an ejection nozzle 100, connected by a pipe to a reservoir or a supply 102 of cleaning fluid, a compressor 101 being interposed between said reservoir and said nozzle 100. As an indication the high ejection pressure of the fluid is of the order of 120 ⁇ 10 5 Pa at 200 ⁇ 10 5 Pa.
  • the cleaning fluid is preferably water or steam, hot or cold.
  • the ejection nozzle is configured so that the jet of cleaning fluid is in the form of a fluid blade or brush 103 and not a simple cylindrical jet.
  • this blade 103 has a flared, triangular shape between the ejection end of the nozzle and the hull 2 of the boat and, seen from the front, in FIG. , an oblong shape of small width L 1 .
  • This blade 103 extends vertically.
  • the width L 1 of this blade is approximately 0.2 to 1 cm and its height H is about 5 at 30 cm.
  • the nozzle 100 is held between 5 and 30 cm from the surface to be cleaned, depending on the energy required to pick up the accumulated dirt and the programming of the means for moving the cleaning unit 1, and will be described later.
  • the length L 2 of this blade of water also varies from about 5 to 30 cm.
  • the ejection nozzle 100 is advantageously provided on its rear face opposite to that in which the fluid blade 103 is ejected, with means 104 for generating a compensatory reaction force to that resulting from the ejection of the cleaning fluid 103.
  • These means 104 are for example fluid ejection means intended to counter the reaction force exerted on the nozzle 100 under the propulsion effect generated by the fluid plate 103.
  • These means 104 may be constituted by a nozzle ejecting a liquid or a gas brought from outside the cleaning unit 1 or by a pump for recirculating the seawater in which the cleaning unit 1 is bathed.
  • the cleaning unit 1 further comprises means 11 for generating a low pressure gas jet.
  • the pressure of the gas is greater than the pressure prevailing at the depth of water at which the cleaning takes place. This pressure is for example from about one tenth of a bar to a few bars (1 bar being equal to 10 5 Pa).
  • These means 11 comprise a ramp 110 provided with a series of nozzles 111, connected to a reservoir or a gas supply 113 via a booster 112.
  • This gas is advantageously air for reasons of availability.
  • the set of bubbles and air jets 116 created at the level of the ramp 110 make it possible to define a space 114 that is free or practically free of water, (for example seawater, if the boat is in a harbor or freshwater if the boat is on a lake), extending in cross section in a shape, slightly flared upward, towards the surface of the water, (see Figure 2).
  • water for example seawater, if the boat is in a harbor or freshwater if the boat is on a lake
  • the space or volume 114 contains a mixture of a little water in which the boat is bathed and a lot of gas from the ramp 110. As a result, inside this volume, the density is significantly reduced compared to that of the surrounding water.
  • This ramp 110 is integral with the nozzle 100, it is disposed under the latter, so that its longitudinal axis extends substantially in the same vertical plane as the one passing through the axis of ejection of said nozzle 100 is that is, the axis of ejection of the fluid blade 103 and that the nozzles 111 of said ramp are under the fluid blade 103.
  • the fluid blade 103 is therefore located inside the space 114 free or substantially free of water, this space 114 extending longitudinally over the entire length of said blade 103, from the nozzle 100, to the surface of the shell 2 to be cleaned.
  • this ramp 110 can be articulated with respect to the nozzle 100 so as to have a slight inclination downwards, by an angle ⁇ , with respect to the axis of ejection of the nozzle 100.
  • This makes it possible to orient the flow of gas so that it always surrounds the fluid blade 103, whatever the point of the shell in front of which the cleaning unit 1 is located.
  • the angle ⁇ is calculated so that the base of the triangular jet of the cleaning fluid is parallel to said ramp.
  • the ramp 110 is provided with means for channeling the gas jets 116, such as one or more deflectors 115 extending along its entire length, making it possible to channel the bubbles and the gas jets 116 in the area surrounding the fluid blade 103.
  • means for channeling the gas jets 116 such as one or more deflectors 115 extending along its entire length, making it possible to channel the bubbles and the gas jets 116 in the area surrounding the fluid blade 103.
  • the cleaning unit 1 is mounted on an articulated arm 3, itself connected to a fixed support 30, mounted on a dock or a pontoon 31.
  • This articulated arm 3 moves said unit 1 in three directions perpendicular to each other.
  • the unit 1 can move in three dimensions in order to follow the shape of the shell 2 to be cleaned.
  • This articulated arm 3 can be controlled by a computer 4 or programmable controller.
  • FIG. 4 A second embodiment is illustrated in Figure 4.
  • several cleaning units 1 are mounted on a support 5, hinged so as to marry the shape of the shell 2 of the boat to be cleaned.
  • This support 5 is mounted on at least one guide rail 50, provided on the dock or the pontoon 31 at the edge of which the boat to be cleaned is moored.
  • This support 5 can slide on this guide rail 50, being controlled by a computer or a programmable controller identical to that mentioned above (but not shown in the figures), so as to move said cleaning units 1 over the entire length of the boat.
  • the installations as represented in FIGS. 3 and 4 may furthermore comprise sensors for measuring the shape of the immersed portions 2 to be cleaned, connected to said computer or programmable automaton for controlling the movement of the unit or cleaning units 1 to the shape of the hull 2.
  • measurement sensors can be of any known type, in particular mechanical (probes) or opto-electric, for example similar to those used in certain automatic car cleaning installations, and as described for example in the document EP 0 507 757 .
  • the measurements taken are stored in a computer and transmitted to a means for controlling the displacement of the articulated arm 3 or articulated support 5.
  • the invention also relates to a method of cleaning the immersed parts in the water of a boat.
  • This method comprises the steps of directing a jet (or blade) of cleaning fluid under high pressure, on said immersed portions 2, while simultaneously ejecting under the jet of fluid, gas jets 116, so as to define a space 114 filled with very little water and much gas or gas only, in which the density is significantly reduced compared to that of the surrounding water.
  • a space 114 - free or substantially free of water - is thus formed around said jet of cleaning fluid 103 to isolate said jet of fluid from the surrounding water body. This space 114 extends over the entire length of said jet of cleaning fluid 103.
  • This method may for example be implemented using the aforementioned device.
