Definitions

  • the present invention relates to a device for cleaning walls, in particular ship walls with a pot-like housing, in the interior.
  • a large number of cleaning nozzles is arranged and the open end face of which is surrounded by a flexible cup sleeve with a sealing ring, which in the operating position of the device rests in a largely sealing manner on a wall to be cleaned, so that the entire device is connected to one by a vacuum generated inside the housing wall to be cleaned can be held self-adhesive.
  • the pot-like housing is usually attached to a support frame provided with rollers or wheels, so that the entire device can be moved along a wall to be cleaned.
  • the flexible cup sleeve ensures that the sealing ring is largely fully in contact, even on uneven or rough surfaces.
  • the sealing ring itself is designed in such a way that, due to the negative pressure generated in the pot-like housing, sufficient adhesive forces can be built up, but do not impede the mobility of the entire device.
  • the sealing ring When moving the device, the sealing ring is relative to one to be cleaned
  • cup sleeve is attached to the outer circumference of the housing via a clamping ring.
  • the present invention has for its object to provide a device of the generic type in which an easy replacement of the sealing ring is possible and the life of the sealing ring is increased.
  • sealing ring is detachably connected to the cup sleeve.
  • the sealing ring If it becomes necessary to change the sealing ring, it can be removed from the cup sleeve relatively quickly and replaced with a new, unused sealing ring.
  • the cup sleeve itself does not need to be detached from the housing, so that the sealing ring can be changed within a very short time.
  • the sealing ring can be connected to the cup sleeve by means of an all-round Velcro strip.
  • the sealing ring can be firmly connected at the top with a flexible jacket which bears on the cup sleeve by being put on and thus creates the connection between the latter and the sealing ring.
  • the sealing ring can also be connected to the cup sleeve by means of an adhesive tape or by means of a plurality of adhesive tape sections, with the prerequisite here, of course, that an adhesive tape or that adhesive tape sections are used, the adhesive force of which allows the sealing ring to be removed from the pot sleeve relatively easily if necessary.
  • the sealing ring itself generally consists of a flexible material, it being regarded as particularly advantageous if the sealing ring consists of a non-slip plastic, a fleece or a textile carpet material.
  • the textile sealing ring in the area of its outer surface lying on a wall to be cleaned is made largely wear-resistant by heat treatment.
  • the inner and outer edges are rounded in order to avoid running over ridges and shoulders, e.g. Welds, to facilitate.
  • the plastic used has antistatic properties so that the device can also be used in potentially explosive environments.
  • connection to the pot sleeve does not exist over the entire surface, but rather via the jacket in an articulated manner on a concentric circular line, preferably in the front third of the ring width.
  • This enables a favorable adaptation to unevenness, e.g. Dents in the ship's wall.
  • a spring element, e.g. Foam be provided in the rear area of the ring width, which also has a stabilizing effect.
