The invention provides an intelligent protection device for electric power construction and maintenance, which includes a rotating handle, an adjusting screw, a deep groove ball bearing, a pedal seat, a fastening nut, an internal threaded pipe, a card seat, an upper clamping frame, a lower clamping frame, and a locking frame. Iron pins, cables, portable high-altitude protective fixed cover structure, static electricity collection temporary storage protector structure, self-locking sliding high-altitude tool lifting wheel structure and intelligent data transmission detection rod structure, the rotating handles are respectively The horizontal welding is on the left and right sides of the bottom of the adjusting screw rod. The setting of the carrying ring, protective plate and connecting plate of the present invention is beneficial to solve the problem that the operator still works at high altitude and in the open air due to the lack of high-altitude protection function. The protective plate and connecting plate can be carried to high altitude through the hand-held carrying ring, and used according to requirements , It can carry out protective work for high-altitude open-air operations to ensure the protective effect of operators, avoid rain or direct sunlight, and play a protective role.
