Automatic washing system and apparatus for tall building

Abstract

An automatic washing system and apparatus for tall building, comprising: a winding device, provided at the top of a tall building for the winding of a cable; a washing device, connected to the control side of the cable and controlled to lift up and down along the outside surface of tall building, a powered roller with brush or fabrics strips attached therewith being provided at the front side of washing device; a forced draft generating device, including a plurality of fan provided at the rear side of said washing device to discharge the air in a direction that is opposite to the outside surface of tall building, so that the negative wind pressure generated relative to the washing device can force the powered rolled at the front side against the outside surface of tall building. In this way, the outside surface of a tall building can be efficiently cleaned by the automatic washing system and apparatus of present invention.

What is claimed is:  
     
         1 . A washing system and apparatus for tall building, characterized in that it comprises: 
 a suspension device, which is provided at the top of a tall building for the winding of a cable at one end;    a washing device, which is suspended at the other end of said cable and is controlled to lift up and down along the outside wall surface of tall building;    a forced draft generating device, which is provided at the rear side of said washing device to generate high speed air stream in a direction that is opposite to the outside surface of tall building, so that the washing device can press against the outside wall surface of tall building.    
     
     
         2 . A washing system and apparatus for tall building as claimed in  claim 1 , wherein said washing device contains powered brush roller or powered fabrics strips roller.  
     
     
         3 . A washing system and apparatus for tall building as claimed in  claim 1 , wherein said forced draft generating device contains at least one electric fan.  
     
     
         4 . A washing system and apparatus for tall building as claimed in  claim 1 , wherein said washing device is composed of a number of small units flexibly connected together.  
     
     
         5 . A washing system and apparatus for tall building as claimed in  claim 1 , wherein said roller is composed of a number of small units flexibly connected together.  
     
     
         6 . A washing system and apparatus for tall building, characterized in that it comprises: 
 a winging device, which is mounted at the top of a tall building for the winding of a cable at one end;    a washing device, which is suspended at the other end of said cable, which is controlled to move up-and-down along the outside wall of the tall building, and the front side of which is provided with a plurality of powered rollers for washing the outside wall surface of tall building;    a plurality of electric fans, which are provided at the rear side of the washing device, which can generate a wind pressure, and the reaction force of which can press the washing device against the outside wall surface of tall building;    a water tube, which moves with the washing device for providing water required for washing;    a power cable, which moves with the washing device for providing electric power required.    
     
     
         7 . A washing system and apparatus for tall building as claimed in  claim 6 , wherein the outside periphery of said roller is provided with brushes and fabrics strips.  
     
     
         8 . A washing system and apparatus for tall building as claimed in  claim 6 , wherein said washing device is composed of a number of small units flexibly connected together.  
     
     
         9 . A washing system and apparatus for tall building as claimed in  claim 6 , wherein said roller is composed of a number of small units flexibly connected together.
