Definitions

  • the invention relates to a system for cleaning a surface.
  • Different equipment or structures may be subject to deposits of various types on their external or internal surfaces. These deposits can affect their proper functioning or performance, or at least their visual and aesthetic appearance.
  • Cleaning systems are known to limit the clogging of a surface with dirt.
  • soiling of a surface we mean here the deposition of foreign bodies on this surface, these foreign bodies being capable, by their presence on this surface, of harming the functioning or the durability of this surface or of the structure to which she belongs to.
  • This concerns for example, the formation of frost on surfaces such as airplane wings or wind turbine blades, or on cables, such as electric cables, bridge stays or carrying cables or motors.
  • transportation systems such as cable cars. It may also involve the deposition of marine biofouling (“biofouling” in English) on submerged surfaces such as the hulls of ships, underwater pipes or marine hydrocarbon extraction platforms.
  • Other types of surface contamination are linked to the deposit of scale or other minerals in the tubes, or to the formation of hydrates in hydrocarbon transfer pipelines.
  • anti-fouling paints or coatings are often used. These, most often based on copper, prevent to a certain extent the attachment of marine organisms. But the result is not satisfactory, especially when the boat's sailing speed is not high enough (less than 15 knots).
  • Some coatings operate on a mechanical level; thus, silicone-based coatings make it possible to limit the accretion of marine organisms due to their low adhesion coefficient. These coatings have a high cost price and here too a cruising speed greater than 15 knots is required to obtain satisfactory efficiency.
  • This device has drawbacks.
  • the area of the cleaned surface is limited to areas at sea level.
  • this device only imperfectly cleans the circumference of the pillar.
  • the shape that this surface can present is also limited to the case of cylindrical surfaces.
  • this device cannot be used effectively on all surfaces.
  • Existing solutions consist of the use of very expensive special coatings, or otherwise periodic cleaning by circulating special machines inside them.
  • an operating shutdown is necessary, with an economic impact.
  • operating performance deteriorates over time.
  • a refrigeration device which includes a crushed ice circuit and a grater system placed under or embedded in a block of ice to form crushed ice, in the interior volume of a tray.
  • the system includes a grid with a rectangular or rasp effect attached to a frame and can slide along vertical uprights installed in the interior volume of the bin. This grater system is used in a particular context to form small pieces of ice.
  • the invention aims to resolve one or more of the drawbacks listed above.
  • An assembly including a surface to be cleaned and provided with a cleaning system, in accordance with claim 1.
  • the invention has a much better operational performance.
  • the invention has a much better operational performance.
  • By allowing almost continuous cleaning of surfaces during operation not only is the performance of the equipment or structure maintained over time, but also the operating shutdowns necessary when implementing existing methods are avoided.
  • the proposed solution is simple and robust, ensuring greater operational reliability over time, compared to existing solutions.
  • the bridge 2 here comprises a plurality of cable-stays, the respective exterior faces of which must be cleaned in order to limit the formation of ice or frost on this cable-stay during winter weather conditions.
  • each of these stays is equipped with a surface cleaning system.
  • This stay 5 has a homogeneous cylindrical shape and here extends longitudinally in an essentially rectilinear manner between its two ends 6 and 8. This stay 5 is stressed in traction.
  • the elements 20 extend in a first direction collinear with the direction X and are spaced from each other in a second direction distinct from the first direction. These elements 20 are here identical and have the same length.
  • the elements 22 are in particular capable of cleaning the surface 10 by scraping when these elements 22 are moved in the direction extend in the second direction and are spaced from each other in the first direction.
  • first and second directions correspond, respectively, to the X and Y directions.
  • each element 22 extends in the Y direction and therefore has a non-zero curvature.
  • Each element 22 therefore has a circular shape here.
  • the elements 22 mainly play the role of scraping elements, while the elements 20 mainly play the role of traction elements of the elements 22. Cleaning of the surface 10 is thus carried out here by scraping this surface with elements 22.
  • the mesh of the net 12 also has a homogeneous distribution and a regular spacing of the elements 20 and the elements 22.
  • d1 the distance between two elements 20, measured in the direction Y and along the element 22
  • d2 the distance between two elements 22, measured in the direction so that the number N of elements 20 of the net 12 is between two and twenty.
  • this number N is between four and eight.
  • the stay has a length ranging from 20m to a few hundred meters and a diameter greater than or equal to 10cm or 20cm or 50cm.
  • the distance d2 and the number M of elements 22 are also chosen according to the dimensions of the stay 5.
  • the distance d2 is for example between D/2 and 10*D.
  • this distance is between 2*D and 5*D.
  • the distance d2 is between 40cm and 1 m.
  • the net 12 is configured to resist tensile forces greater than 10kN.
  • the net 12 is made of metallic material.

  • each element 22 when it is at rest is preferably less than the radius of curvature of the surface 10.
  • An element 22 is said to be at rest when it is not pressed against a surface such as the surface 10.
  • each element 22 is elastically deformed during its pressing against the surface 10.
  • the plating pressure is however optimized, in order to guarantee good guidance of the net on the surface, while generating a minimum of resistance to the movements of the net on the surface to be cleaned.
  • the scraping surface is much smaller than the surface to be cleaned, which makes it possible to reduce the efforts necessary for the device 14 to be able to drive the net 12.
  • the surface area of the zones of the surface 10 which are in contact with the elements 22 is less than 3% or 1% of the total surface area of the surface 10.
  • the total surface area of the orthogonal projection of the net 12 on the surface 10 is less than 5% or 3% or 1% of the total surface area of the surface 10, this projection being carried out in a direction normal to the surface 10 .
  • the exterior face portion of the elements 22 in contact with the surface 10 is covered with a protective coating.
  • This protective coating has the function of limiting the abrasion of the element 22 or the surface 10 without to limit the ability of the elements 22 to scrape the surface 10.
  • This protective coating comprises for example Teflon or high density polyethylene.
  • the net 12 thus extends between so-called axial ends and here joined to the device 14.
  • the ends are here each formed by a rigid metal ring 24a, 26a encircling the stay 5 and being able to move relative to this stay 5 along the direction X.
  • the ends of each of the elements 20 are attached to these axial ends.
  • These rings are here respectively attached to the device 14 by drive cables 24b, 26b.

  • the width of these rings 24a, 26a, measured in the direction X is here less than 20cm.
  • the net 12 has dedicated openings to the right of these protuberances. Thus, the net 12 will be able to move back and forth without hindrance, the dedicated openings moving around the protuberances while encircling them.
  • the device 14 is configured to move the net 12 with a back and forth movement in the direction X and with an amplitude of movement at least equal to the average distance between the second wire elements.
  • the device 14 is configured to periodically move the net in the direction X by a distance d greater than or equal to the distance d2.
  • the distance d is less than or equal to 3 times the distance d2.
  • the entire surface 10 is scraped by the different elements 22 by moving the net 12 with an amplitude d which is reduced compared to the total dimensions of the surface 10. This makes it possible to reduce the power and/or the bulk of device 14.
  • Each of these actuators 30, 32 is configured to exert a traction movement in the direction X in a particular direction of movement, the respective directions of movement of these actuators 30 and 32 being opposite.
  • the frequency of movements is programmed in module 34 so that the thickness of ice forming on the stay between two successive passages is low. In this way, the quantity of energy consumed by the cleaning device will be optimized and the stresses induced in the device will remain within acceptable values.
  • Actuators 30 and 32 are identical here. These actuators 30 and 32 each comprise here a winch secured without degree of freedom to the surface 10. Here, the actuators 30, 32 are placed respectively at the two ends of the stay 5. The winch of each of the actuators 30 and 32 here respectively actuates the drive cables 24b and 26b.
  • the system 4 is removable, that is to say it can be dismantled and then reassembled on the stay 5.
  • the net 12 has a longitudinal opening (not shown in the figures). This opening is for example formed by two contiguous elements 20 capable of being selectively maintained in direct contact with one another over their entire length, for example by means of a lock or an adhesive material.
