Method and apparatus for removing material from object surface

1. An apparatus ( 10 ) for removing material deposited on an object surface ( 102 ), the apparatus ( 10 ) being attached to or configured to accommodate an object ( 100 ), comprising

an elastic mechanical cleaning device ( 310 ) arranged to a first driving unit ( 321 ) at a first end and arranged to a second driving unit ( 322 ) at a second end, the first driving unit ( 321 ) and second driving unit ( 322 ) being configured to move the respective first and second ends of the elastic mechanical cleaning device ( 310 ) in a circumferential direction relative the object surface ( 102 ),

wherein

the second driving unit ( 322 ) is configured to move inside the first driving unit ( 321 ),

the first driving unit ( 321 ) and second driving unit ( 322 ) move in opposite relative directions from one another, and

the opposite relative movement of the first driving unit ( 321 ) at the first end and the second driving unit ( 322 ) at the second end causes a tightening and a loosening of the elastic mechanical cleaning member ( 310 ) and provides a random cleaning pattern over the object surface ( 102 ) to remove material deposited on the object surface ( 102 ).

2. The apparatus according to claim 1 , wherein the mechanical cleaning device ( 310 ) is an elastic element.

3. The apparatus ( 10 ) for removing material according to claim 1 , wherein the mechanical cleaning device ( 310 ) is driven by one from the group consisting of via cleaning fluid, mechanically and electrically.

4. The apparatus ( 10 ) for removing material according to claim 1 , comprising a drive unit ( 320 ) for driving the mechanical cleaning device ( 310 ) that comprises one or more from the group consisting of a rotor ( 321 ), chain ( 360 ), wire, belt and thread.

5. The apparatus ( 10 ) for removing material according to claim 1 , comprising a locking mechanism ( 330 ) for selectively preventing operation of the mechanical cleaning device ( 310 ).

6. The apparatus ( 10 ) for removing material according to claim 2 , comprising a locking mechanism ( 330 ) for selectively preventing operation of the mechanical cleaning device ( 310 ).

7. The apparatus ( 10 ) for removing material according to claim 1 , comprising a body ( 11 ) having an opening ( 12 ) with a circumferentially extending flexible part, flange or lip ( 13 ) partially covering the object surface ( 102 ) in the circumferential direction relative thereto and in engagement with the object surface ( 102 ) with a pretension force.

8. The apparatus ( 10 ) for removing material according to claim 7 , wherein the apparatus ( 10 ) is arranged to supply cleaning fluid interior of the body ( 11 ) and the flexible part, flange or lip ( 13 ) is arranged to bend away from the object surface ( 102 ) when subjected to cleaning fluid supplied interior of the body ( 11 ).

9. The apparatus ( 10 ) for removing material according to claim 1 , wherein the apparatus ( 10 ) is arranged to supply cleaning fluid in contact with the object surface ( 102 ) and until it is ejected away from the object surface ( 102 ).

10. The apparatus ( 10 ) for removing material according to claim 1 , wherein the apparatus ( 10 ) is configured to supply cleaning fluid in a circumferential direction relative to the object surface ( 102 ) with a flow from the circumferential direction towards center of the object surface ( 102 ) where it is ejected mainly perpendicularly away from the object surface ( 102 ).
