Load rejection structure for underwater equipment

The load rejection structure comprises an equipment body, a load rejection part is fixedly connected to the bottom face of the equipment body, a cylindrical sliding cavity is formed in the center of the bottom face of the load rejection part, a cylindrical weight block is slidably connected into the cylindrical sliding cavity, and a weight arc-shaped bottom is fixedly connected to the bottom face of the cylindrical weight block. The top face of the arc-shaped bottom of the heavy object makes contact with the bottom face of the load rejection part, four load rejection columns are evenly and fixedly connected to the top face of the arc-shaped bottom of the heavy object, and four installation column grooves are formed in the positions, corresponding to the four load rejection columns, of the bottom face of the load rejection part respectively. The four load rejection columns and the four load rejection sleeves corresponding to the four load rejection columns are uniformly arranged, so that load rejection stress
