FIELD: agriculture. ^ SUBSTANCE: underwater farm includes net cages installed on frame having positive buoyancy and submerging apparatus including hawses, anchor wires, anchors, large-diametre drums, small-diametre drum and rigid pulleys installed on the upper part of the frame. Drums are fixed rigidly on frame-supported shaft capable to rotate on bearings. In addition submerging apparatus includes cable-supported load kinematically connected by means of cable to small-diametre drum, one end of cable being fixed and partly wound on small-diametre drum and another end of cable being fixed to load. One end of anchor wire is fixed to large-diametre drum and the other end is fixed to anchor. Large-diametre drums are kinematically connected by means of corresponding anchor wires with the help of corresponding rigid pulleys and hawses to corresponding anchors. Load is kinematically connected by means of cable to small-diametre drum through corresponding rigid pulley. MëÑN+K, where M - number of rigid pulleys, N - number of additional large-diametre drums, and K - number of loads. ^ EFFECT: such structure ensures convenient operation, simplified design and deepening of farm submerging. ^ 2 cl, 3 dwg |
