Definitions

  • This invention describes a window-cleaning machine for cleaning windows and other external surfaces of buildings, ships, airplanes, tanks, silos and the like.
  • the machine comprises a securing device with multiple cables that allow the main cleaning body to be positioned at any point on the facade of the building, hull of the ship, fuselage of the plane, etc., whether this surface is regular or irregular.
  • the process of cleaning high-rise buildings can be a dangerous operation. Indeed, it has been shown that at great heights the wind and drafts can generate aerodynamic forces on the structure or device used for cleaning (for example: scaffolding or climbing robots) causing it to swing away from the building, endangering the workers and the equipment.
  • the structure or device used for cleaning for example: scaffolding or climbing robots
  • Patent US 36649 by Jesse H. Jefferies describes a system that improves stability through the use of a counterweight installed in the bottom portion of the building.
  • the mobility factor continues to be limited due to the fact that the system only moves vertically.
  • the window-cleaning machine of the present invention overcomes the technical problems of the known systems that have been described above.
  • the invention consists of a window-cleaning apparatus comprising a plurality of securing cables, preferably at least four of them, in order to ensure its stability. Said cables are directly or indirectly joined to the top portion and bottom portion (or other positions) of a surface to be cleaned.
  • the cleaning apparatus comprises a main cleaning body that is secured to the cables by means of springs that provide suitable securing and stability.
  • the length of the cables is chosen such that the entire surface one wishes to clean may be covered.
  • the cables secured to the top portion of the surface are connected to a motorized mechanical transmission or other system in order to pull it.
  • the cables connected to the bottom portion of the surface may be connected to a motorized mechanical transmission, counterweights, or another equivalent system. Other cables at other points may be connected in a similar fashion.
  • These mechanical transmissions are directly or indirectly connected to motors.
  • the motors can wind up or unwind the cables such that the cleaning apparatus may be positioned at any position on the surface.
  • a control unit controls the planning of the motors' movement.
  • the position of the cleaning apparatus is determined by means of at least one sensor arranged on the main cleaning body.
  • the apparatus comprises a plurality of sensors that may include position sensors, speed sensors, revolution counters, inertia sensors, image sensors or equivalent systems.
  • a plurality of assemblies of omnidirectional wheels is secured to the main cleaning body.
  • the wheel assemblies are arranged on the edges of said cleaning apparatus.
  • the omnidirectional wheels may be wheels with rollers joined to their circumference (said rollers being arranged on rotation shafts arranged at 45° with respect to the plane of the wheel and 45° with respect to the line passing through the roller parallel to the rotation shaft of the wheel), ball-type wheels, or equivalent wheels.
  • the wheel assemblies have a star formation or equivalent, with three wheels in each wheel assembly. This star formation enables the apparatus to overcome obstacles.
  • the cleaning apparatus has a set of brushes that, in one exemplary embodiment, may be circular brushes.
  • the cleaning supplies such as water or detergent, may be housed in tanks installed in the main cleaning body, or may be provided by means of a hose connected to tanks arranged outside the main body and which are preferably situated at the top portion of the surface to clean.
  • the described window-cleaning device may be operated autonomously or remotely.
  • the main objective of this invention is to enable a window-cleaning machine to be positioned at any position on the surface of a wall of a building, ship, airplane, etc.
  • Another objective of this window-cleaning machine is to overcome any obstacle or irregularity on the surface of the wall.
  • Another objective is for the system of multiple cables to be able to provide a stable support for the window-cleaning machine, even in the case of winds and drafts.
  • Another objective is for the machine to be able to carry the necessary load weight of the corresponding cleaning supplies.
