Portable protection device for high-density electrical method electrode change-over switch

The invention relates to the technical field of geological survey, in particular to a portable protection device for a high-density electrical method electrode change-over switch. Comprising a first protection device, a second protection device and a buckling mechanism, the first protection device and the second protection device are each of a hollow structure, the hollow shapes of the interiors of the two protection devices are matched with the shape of the high-density electrical method change-over switch, and two protrusions are symmetrically arranged in the middle of each of the first protection device and the second protection device; the buckling devices are arranged on the protruding portions of the first protection device and the second protection device, cable ports are formed in the two ends of the first protection device and the two ends of the second protection device which are buckled, and semi-dumbbell-shaped sealing pieces are arranged at the positions of the cable ports. The device is convenie
