Cleaning apparatus

Abstract

The invention relates to an apparatus for cleaning surfaces, in particular inclined surfaces, in particular solar installation surfaces or photovoltaic installation surfaces on roofs of buildings, having a carrier and at least one driven endless cleaning belt held at the carrier.

1 . An apparatus for cleaning surfaces, in particular inclined surfaces,  having a carrier ( 11 ) and at least one driven endless cleaning belt ( 13 ) held at the carrier ( 11 ). 
     
     
         2 . An apparatus in accordance with  claim 1 ,  wherein a fluid supply device ( 15 ) is provided which is preferably connectable to a separate high-pressure cleaner ( 17 ). 
     
     
         3 . An apparatus in accordance with  claim 1 , wherein a holding device ( 19 ) connected to the carrier ( 11 ) is provided, with the holding device ( 19 ) and the carrier ( 11 ) being pivotable with respect to one another. 
     
     
         4 . An apparatus in accordance with  claim 3 , wherein the holding device ( 19 ) and the carrier ( 11 ) are mutually pivotable about two different axes ( 21 ,  23 ). 
     
     
         5 . An apparatus in accordance with  claim 3 , wherein the holding device ( 19 ) has a longitudinal axis ( 25 ) and a pivotability of the carrier ( 11 ) relative to the holding device ( 19 ) about the longitudinal axis ( 25 ) of the holding device ( 19 ) is suppressed. 
     
     
         6 . An apparatus in accordance with  claim 3 , wherein at least a part of a fluid supply device ( 15 ) is integrated into the holding device ( 19 ). 
     
     
         7 . An apparatus in accordance with  claim 1 , wherein the drive for the belt ( 13 ) takes place by means of a supplied cleaning fluid. 
     
     
         8 . An apparatus in accordance with   claim 1 , wherein at least one integrated motor is provided for the drive of the belt ( 13 ). 
     
     
         9 . An apparatus in accordance with  claim 1 , wherein at least two endless cleaning belts ( 13 ) are provided which are held at the carrier ( 11 ). 
     
     
         10 . An apparatus in accordance with  claim 1 , wherein the carrier ( 11 ) is provided in modular construction and is preferably configurable in different working lengths in dependence on the kind and/or number of the carrier modules. 
     
     
         11 . An apparatus in accordance with  claim 1 , wherein the carrier ( 11 ) includes at least one drive module for the belt ( 13 ), at least one deflection and/or clamping module for the belt ( 13 ), at least one support module for the belt ( 13 ) and/or at least one extension module. 
     
     
         12 . An apparatus in accordance with  claim 1 , wherein each module includes a tubular or sleeve-like base element for coupling the modules to one another. 
     
     
         13 . An apparatus in accordance with   claim 16 , wherein said apparatus can be coupled to a guiding and holding device ( 67 ) of a solar installation or photovoltaic installation or of a solar installation surface or photovoltaic installation surface ( 59 ). 
     
     
         14 . A solar installation or photovoltaic installation having at least one surface ( 59 ), in particular inclined with respect to the horizontal, and at least one guiding and holding device ( 67 ) for a cleaning apparatus ( 10 ) having a carrier ( 11 ) and at least one driven endless cleaning belt ( 13 ) held at the carrier ( 11 ). 
     
     
         15 . A system of at least one solar installation or photovoltaic installation having at least one surface ( 59 ), in particular inclined with respect to the horizontal, and at least one guiding and holding device ( 67 ) for a cleaning apparatus ( 10 ) and of at least one cleaning apparatus ( 10 ) having a carrier ( 11 ) and at least one driven endless cleaning belt ( 13 ) held at the carrier ( 11 ), wherein the cleaning apparatus ( 10 ) is preferably operable automatically and/or in a self-propelling manner. 
     
     
         16 . An apparatus in accordance with  claim 1 , wherein said surfaces are solar installation surfaces or photovoltaic installation surfaces on roofs of buildings. 
     
     
         17 . An apparatus in accordance with  claim 4 , wherein said axes ( 21 ,  23 ) extend perpendicular to one another. 
     
     
         18 . An apparatus in accordance with  claim 8 , wherein said motor ( 27 ) is an electric motor. 
     
     
         19 . An apparatus in accordance with  claim 9 , wherein said cleaning belts ( 13 ) are drivable independently of one another.
