[0024] See also Figure 4 A combined strip zinc anode comprises: a conductive core 13 is penetrated in the middle of one end of a zinc strip 2, the conductive core 13 coincides with the central axis of the zinc strip 2, an insulating washer 14 is sleeved at the connection between one end of the conductive core 13 and the zinc strip 2, the insulating washer 14 is used to prevent the zinc strip 2 from directly contacting the conductive sheet 3, and reduce the friction damage between the contact surfaces of the zinc strip 2 and the conductive sheet 3; a zinc plate 15 is welded to the outer wall of the end of the zinc strip 2 away from the base 1, and the zinc plate 15 forms a semi-enclosed structure between the zinc strip 2 and the conductive core 13, the conductive core 13 is used to increase the power-on efficiency when the zinc strip 2 is used as an anode, and the bottom end is protected by the zinc plate 15 to prevent the conductive core 13 from being electrochemically corroded.

[0025] Working principle: For this type of combined strip zinc anode, the staff first loosens the adjusting bolts 12 on the base 1 to move the clamping blocks 11 to both sides of the base 1, and then inserts the zinc strip 2 to be installed into the inner side of the base 1 and tightens the adjusting bolts 12 so that the base 1 clamps the zinc strip 2 through the clamping blocks 11 to prevent the zinc strip 2 from falling off the base 1 when used as an anode. Then, the staff pulls the wire 7 outward from the wire drum 4 on the base 1 according to the required length of the wire 7. The redundant wire 7 is wound on the winding post 6 in the cavity 5, and the other end of the wire 7 passes through the winding post 6 and through the threading tube 8, and is connected to the upper end surface of the conductive sheet 3 in contact with the zinc strip 2. The conductive wire 7 and the conductive sheet 3 can be electrically connected to the conductive core 13 on the zinc strip 2. After the conductive wire 7 is pulled out to a certain length, the gravity of the anode when it is hung down for use is close to the elastic force of the torsion spring 10 on the inner side of the swivel seat 9, so that the conductive wire 7 will not automatically retract due to the elastic force of the torsion spring 10, and the applicability is good. Finally, the zinc strip 2 increases the efficiency of the zinc strip 2 when it is used as an anode through the conductive core 13, and the zinc plate 15 welded at the lower end of the zinc strip 2 is used to protect the conductive core 13, and the insulating gasket 14 is used to reduce the wear between the conductive sheet 3 and the upper surface of the zinc strip 2. When the zinc strip 2 is greatly worn and needs to be replaced, it only needs to quickly retract the conductive wire 7 through the elastic force of the torsion spring 10 and loosen the adjusting bolt 12 to achieve rapid disassembly and assembly of the zinc strip 2.
