Abstract

The invention discloses a deep sea net cage fish crossing prevention device. The device comprises an annular floating plate, wherein a net cage is arranged at the lower end of the annular floating plate, a plurality of fixing rods are fixed to the upper end of the annular floating plate, a protective net is arranged on the outer sides of the fixing rods, a pair of cross plates is fixed to the upper inner wall and the lower inner wall of the annular floating plate, a rotating shaft is rotatably connected between the inner walls of the middles of the cross plates, four pull rods hidden between the cross plates are fixed to the outer wall of the rotating shaft, a blocking net is arranged between the pull rods and the inner walls of the cross plates, one side of the blocking net is fixed to the side walls of the pull rods, the other side of the blocking net is fixed to the inner walls of the cross plates, four arc-shaped cavities are arranged in the annular floating plate, first pistons are arranged in the arc-shaped cavities, and magnetic blocks are fixed to the side walls of the first pistons. The device is reasonable in structure, a cage opening of the deep sea net cage can be automatically shielded through the blocking net in strong wind and strong wave weather, meanwhile, the height of the protective net is increased, and therefore the situation that cultured fishes cross thenet is avoided.

Description

technical field [0001] The invention relates to the technical field of deep-sea net cages, in particular to a deep-sea net cage anti-fish escape device. Background technique [0002] The deep-sea net cage is mainly composed of frame system, mesh bag, fixing system and supporting facilities. The interaction of the fixed platform and the characteristics of the box body are used to lower the box body to a limited depth underwater. Since the wave strength will increase exponentially with the water depth Attenuation rapidly, the wave intensity at the place where the cage is located at a certain depth will also decrease exponentially, so as to achieve the purpose of resisting wind and waves. [0003] However, when the existing deep-sea cages encounter strong winds and waves, although they can resist strong wind and waves, under the influence of wind and waves, the water inside the deep-sea cages will also flip. Fish may jump over the net and cause property damage. Contents of t...
