The invention relates to a device for drawing a net under ice. The device comprises an elongated frame 1 and at least one pontoon 2,3 or a combination of these, a draw mechanism 4, to which a pull cable 5 is fixed, the device being made to move forward under the ice by traction in the cable, and a net barrier 6, to which a cable 7 connected to the net end is fixed when the net is drawn under the ice. The net barrier 6 comprises a rocking member 17,18, which is pivotably fixed to the frame 1. The swivel axis D-D of the rocking member stands at least approximately perpendicular to the longitudinal axis of the frame and to the motional direction B of the device and the rocking member is arranged to swivel between a draw position and a release position for the net. The member has a pin, a hook or a like holding element 20, to which the cable 7 or the like connected to the net end can be fastened and which holding element 20, in relation to a transverse plane E-E through the frame 1, is directed forwards B in the draw position for the net and directed backwards C for the release position. <IMAGE> |
