| 摘要 |
A floating debris collection device (1) comprising flotation members (2) which define a channel (19) into which water and floating debris can flow at a first end (21) towards a second end (22), first and second closure means (7, 8) for the channel adjacent said first and second ends respectively, the first and second closure means each being adapted to restrict floating debris but not water in the channel from flowing out of the channel; the first closure means being movable between an open position in which water and floating debris can flow into the channel and a closed position in which floating debris but not water in the channel is substantially restricted from flowing out of the channel; and means (43) sensitive to the direction of water flow with respect to the channel for moving the first closure means between said open and closed positions.
