Electric power detection device for maintenance of deepwater hydropower station

The invention relates to the technical field of hydropower stations, and discloses an electric power detection device for maintenance of a deepwater hydropower station. The devicecomprises a connecting pipe, the inner surface of the connecting pipe is movably connected with a movable rod, the top and the bottom of the connecting pipe are both provided with limiting grooves, and the inner surfaces of the two limiting grooves are both movably connected with limiting plates. The opposite sides of the two limiting plates are fixedly connected with the outer surface of the movable rod, a buffer plate is fixedly connected to the right side of the movable rod, an annular groove is formed in the outer surface of the connecting pipe, sliding blocks are movably connected to the top and the bottom of the annular groove correspondingly, and an adjusting wheel is movably connected to the outer surface of the connecting pipe. The sides, away from each other, of the two sliding blocks are fixedly connected with the inner su
