1. A device for repairing deep-water cage nets, comprising an open-frame underwater robot and a repairing mechanism of deep-water cage nets, wherein the repairing mechanism of deep-water cage nets comprises a hole penetrating mechanism, a wire feeding mechanism, a rotary knotting mechanism, a steel wire cutting mechanism and steel wire clamping mechanisms;
wherein the hole penetrating mechanism comprises mechanical claws and a control box for controlling the mechanical claws, the wire feeding mechanism and the steel wire cutting mechanism are both fixedly arranged in the control box, and the steel wire clamping mechanisms and the rotary knotting mechanism are both arranged between two mechanical claws outside the control box; wherein there are two mechanical claws, the two mechanical claws respectively penetrate through a box body of the control box, and the inner sides of the two mechanical claws are provided with U-shaped grooves;
the rotary knotting mechanism comprises a second submersible motor and a rotating shaft, a first cylindric straight-teeth gear connected to the second submersible motor, and a second cylindric straight-teeth gear connected to the rotating shaft, wherein the first cylindric straight-teeth gear and the second cylindric straight-teeth gear are meshed with each other; one side of the rotating shaft far away from the second submersible motor is fixedly connected with an intercepting plate, two ends of the intercepting plate are provided with through holes for threading a steel wire, the intercepting plate is located outside the control box and between the mechanical claws, the through holes correspond to cross sections of the U-shaped grooves, and the mechanical claws are provided with grooves for the intercepting plate to move; and
wherein the open-frame underwater robot is detachably connected with the repairing mechanism of deep-water cage nets through a connecting shaft.
