Vertical well ground-penetrating radar detection system and usage method thereof

The invention relates to a vertical well ground-penetrating radar detection system. The system comprises a ground-penetrating radar host, an antenna, a lifting platform and a pulley lifting componentused for lifting and lowering the lifting platform. The pulley lifting component includes a sliding wheel, a steel wire rope, an electric folding and unfolding component and a support. The support isfixed above a vertical well, and the sliding wheel is rotatably connected to the support and is located above the vertical well. Two ends of the steel wire rope are fixed on the electric folding and unfolding component and the lifting platform, and a center of the lifting platform is vertically provided with a vertical rod. The vertical rod is vertically provided with a cross rod, and a sliding rod passes through and is slidably connected to the cross rod. One end of the sliding rod, away from the vertical rod, is fixed to the antenna, and the cross rod is provided with a slot along a length direction. The vertical rod
