[0002] The zinc alloy sacrificial anode for buried water supply pipes is a structure used to prevent the buried water supply pipeline from being corroded in the soil environment; by utilizing the activity of the zinc alloy, it serves as an anode in the soil environment and prevents the cathode connected to it, that is, the water supply pipeline, from being corroded through its own oxidation reaction; a protection device can be set to protect the zinc alloy sacrificial anode.

[0003] After the zinc alloy is buried inside the soil, different cross-sections of the zinc alloy will react with the soil, resulting in a relatively fast loss rate of the aluminum alloy and affecting the service life of the aluminum alloy; therefore, an improved zinc alloy sacrificial anode protection device for buried water supply pipes is proposed to solve the above problems.
