Blade nut detection device for wind power generation maintenance and use method

The invention relates to the field of blade nut detection, in particular to a blade nut detection device for wind power generation overhaul and a using method, the blade nut detection device comprises a frame body, a flange plate is inserted in the frame body, and a plurality of nuts arranged in an annular array at equal intervals are arranged on the outer wall of the flange plate; a transmission mechanism is arranged in the inner wall of the frame body, and a detection mechanism used for nut detection is movably arranged in the inner wall of the frame body. According to the blade nut detection device for wind power generation overhaul, the V-shaped blocks on the clamping blocks are used for screwing nuts, then the pushing blocks and the movable frame are arranged, whether each nut on a blade flange plate is loosened or not can be continuously and sequentially checked, the nuts on the back face of a blade can also be checked, and the detection efficiency is improved. A worker can complete the detection of the
