Anode clamping device

An anode clamp configured to clamp an anode rod to an anode bus, the anode clamp comprising a first rotating mechanism and a second rotating mechanism;

• the first rotating mechanism comprising:
• a first pin that is rod-shaped and configured for being rotated by a user around a longitudinal axis of the first pin;
• a cam having a main body shaped as an arc of a cylinder, the cam having an outer surface having a cylindrical section and a non-cylindrical section, the cam being joined to the first pin such that a central axis of the cylinder is parallel to and separate from the longitudinal axis of the first pin, the cam being configured to rotate with the first pin around the longitudinal axis of the first pin;
• a first gear joined to the cam, the first gear having at least one first tooth extending radially away from the first pin, the at least one tooth being adjacent to the non-cylindrical section of the cam and opposite to the cylindrical section of the cam;
• the second rotating mechanism comprising:
• a second pin parallel to the first pin;
• a pawl joined to the second pin and rotatable around the second pin, the pawl comprising a clamping pad configured to contact the anode rod and apply pressure on the anode rod, the clamping pad comprising an electrically insulating block configured to contact the anode rod and to prevent electrical current flow from the anode rod to the clamp;
• a roller parallel to the first pin and joined to the pawl such that the rotation of the roller does not cause the pawl to rotate, the roller being configured to contact the cylindrical section of the cam's outer surface;
• a second gear joined to the pawl and rotatable around the second pin, the second gear having at least one second tooth extending radially away from the second gear and configured to engage with the at least one first tooth;
• wherein:
• a first rotation of the first rotating mechanism in a first direction around the longitudinal axis of the first pin causes the cam to roll against the roller, such that a distance between a point at which the cam touches the roller from a center of the first pin becomes larger due to the fact that the main body of the cam is off-center with respect to the longitudinal axis of the first pin, thereby pushing the roller and causing the second rotating mechanism to rotate in a second direction opposite to the first direction around the second pin;
• the second rotation of the second rotating system being such that the clamping pad of the pawl rotates downward to apply pressure on the anode rod located below the clamping pad;
• during the first and second rotation, the at least one first tooth is configured to contact the at least one second tooth before the roller loses contact with the cylindrical section of the outer surface of the cam.
