摘要（英）：

The utility model relates to a waterproof sleeve for a cathode protection device for an underground pipeline system. The waterproof sleeve is arranged in an outer protection pipe (2), and a feed connector (402) is fixedly arranged at the front end of the waterproof sleeve to perform welding operation between the feed connector (402) and an underground pipeline (1). The waterproof sleeve (5) consists of components as follows: a screw (501), a sleeve joint (402), a sleeve connecting pipe (503), a sleeve front end joint (504) and the feed connector (402), wherein the screw (501), the sleeve joint (402), the sleeve connecting pipe (503) and the sleeve front end joint (504) adopt hollow tubular structures; the sleeve connecting pipe (503) and the sleeve front end joint (504) are connected into a whole coaxially; and a feed cable (501) is pre-connected with the sleeve joint (402). The waterproof sleeve can be well applied to a construction process of the cathode protection device for the underground pipeline system, is a necessary auxiliary tool, and can well guarantee the construction effect.
