Abstract

The invention relates to a collecting device ( 1 ) for pollution on a water surface ( 9 ), the collecting device ( 1 ) including tight side walls ( 11 ), a tight end wall ( 12 ), a top portion ( 13 ), floating means ( 2 ), an inlet portion ( 15 ) and an aft collecting portion ( 17 ), and the collecting device ( 1 ) further including a channel portion ( 16 ) between the inlet portion ( 15 ) and the collecting portion ( 17 ), and the bottom portion of the collecting device being capable of through-put.

1 . A collecting device ( 1 ) for pollution on a water surface ( 9 ), the collecting device ( 1 ) comprising:
 tight side walls ( 11 ,  11 ′);   a tight end wall ( 12 );   a top portion ( 13 );   floating means ( 2 );   an inlet portion ( 15 ) and an aft collecting portion ( 17 ); and   a channel portion ( 16 ) between the inlet portion ( 15 ) and the collecting portion ( 17 ) and in the channel portion ( 16 ) and the collecting portion ( 17 ), a bottom portion of the collecting device ( 1 ) has through-put capabilities.   
     
     
         2 . The collecting device ( 1 ) in accordance with  claim 1 , wherein, extending from the inlet portion ( 15 ) through the channel portion ( 16 ), is at least one friction element ( 3 ,  3 ′). 
     
     
         3 . The collecting device ( 1 ) in accordance with  claim 2 , wherein the at least one friction element ( 3 ,  3 ′) extends to the tight end wall ( 12 ). 
     
     
         4 . The collecting device ( 1 ) in accordance with  claim 2 , wherein the at least one friction element ( 3 ,  3 ′) is constituted by a material selected from a group consisting of: a tight material in cloth form; a net; a netting; or a perforated material in cloth form. 
     
     
         5 . The collecting device ( 1 ) in accordance with  claim 2 , wherein the at least one friction element ( 3 ) is attached at an upper edge portion ( 31 ) of the at least one friction element ( 3 ) to the top portion ( 13 ). 
     
     
         6 . The collecting device ( 1 ) in accordance with  claim 5 , wherein the at least one friction element ( 3 ) is releasably attached at an upper edge portion ( 31 ) of said friction element ( 3 ) to the top portion ( 13 ). 
     
     
         7 . The collecting device ( 1 ) in accordance with  claim 5 , wherein the at least one friction element ( 3 ) projects freely down into the water at a lower edge portion ( 33 ) of said friction element. 
     
     
         8 . The collecting device ( 1 ) in accordance with  claim 5 , wherein, at a lower edge portion of the at least one friction element, the friction element ( 3 ) is attached, in a portion, to a shape-stabilizing element ( 6 ) capable of through-put. 
     
     
         9 . The collecting device ( 1 ) in accordance with  claim 1 , wherein, in the inlet portion ( 15 ), the collecting device ( 1 ) is provided with a frame ( 4 ) set substantially vertically in position of application. 
     
     
         10 . The collecting device ( 1 ) in accordance with  claim 9 , wherein the at least one friction element ( 3 ) is attached at a forward, lower edge portion ( 33 ) of said friction element to a lower portion ( 43 ) of the frame. 
     
     
         11 . The collecting device ( 1 ) in accordance with  claim 2 , wherein the at least one friction element ( 3 ′) is attached at side portions ( 31 ′,  33 ′) to the tight side walls ( 11 ,  11 ′) of the channel portion ( 16 ). 
     
     
         12 . The collecting device ( 1 ) in accordance with  claim 11 , wherein the at least one friction element ( 3 ′) is releasably attached at side portions ( 31 ′,  33 ′) to the tight side walls ( 11 ,  11 ′) of the channel portion ( 16 ). 
     
     
         13 . The collecting device ( 1 ) in accordance with  claim 1 , wherein the top portion ( 13 ) is constituted by a tight material in cloth form. 
     
     
         14 . A boom arranged to concentrate pollution on a water surface ( 9 ), the boom being provided with an opening in a collecting portion, the boom having in the opening a collecting device ( 1 ) in accordance with  claim 1 .
