Abstract: An apparatus for dismounting and mounting a high-voltage line T-connector in a hot-line operation includes a lifting platform, a four-axis platform and an end-effector mechanism; the four-axis platform and the end-effector mechanism are both electrically conductive structures; the four-axis platform is fixedly mounted on the top of the lifting platform, and an insulating layer is provided between the four-axis platform and the lifting platform; the four-axis platform is movable in the X direction, the Y direction, and the Z direction, and is rotatable around the Z direction; the four-axis platform is provided with an equipotential mechanism; the end-effector mechanism is detachably fastened to the four-axis platform; and a bolt loosening/tightening mechanism or a nut cutting device capable of moving in the X direction, the Y direction, and the Z direction is provided on the end-effector mechanism.

Abstract: A sea creature cleaning robot for an intake tunnel for a nuclear power plant includes a frame, cutter assemblies, and walking wheel assemblies; the frame is used for mounting and fixing cutter mounting seats and crawler wheels; the walking wheel assemblies mounted on the frame enable the entire device to normally walk in a tunnel; the cutter assemblies control the height of cutters by means of hydraulic cylinders to make the cutters contact the inner wall of the tunnel, and the hydraulic cylinders drive the saw-toothed cutters to move back and forth to remove sea creatures attached to the inner wall of the tunnel; the cutter assemblies are uniformly distributed on the frame, so as to ensure full coverage of the cleaning range of the cross section of the tunnel. The robot can clean sea creatures in tunnels in place of manual work to significantly improve the cleaning efficiency.
