Liquid-leakage detection device

A liquid-leakage detection device, comprising:

• a detection belt body configured to wrap an outer surface of a to-be-detected device;
• an electrode configured to detect whether the to-be-detected device leaks liquid, wherein the electrode is connected to the detection belt body and disposed on one surface or inside of the detection belt body;
• a first connection member connected to a first side of the detection belt body and comprising at least one first buckling part;
• and
• a second connection member connected to a second side of the detection belt body and comprising at least one second buckling part, wherein the second buckling part is capable of buckling with the first buckling part so that the first connection member is connected to the second connection member by buckling,
• wherein part or all of the at least one first buckling part is a hook structure arranged along a length direction of the detection belt body, part or all of the at least one second buckling part is a hook structure arranged along the length direction of the detection belt body, a shape and quantity of the at least one second buckling part are set corresponding to a shape and quantity of the at least one first buckling part, and the hook structure of the at least one first buckling part and the hook structure of the at least one second buckling part are capable of buckling together to form a stable interlocking structure without liquid-leakage.
