Pole collapse prevention device and electric pole

The invention provides a pole collapse prevention device and an electric pole, and relates to the technical field of auxiliary equipment of power facilities. The pole collapse prevention device comprises supporting frames and adjusting assemblies. The adjusting assemblies are connected to the outer side ends of the supporting frames, and can adjust the distance between the supporting frames and the ground. At least three supporting frames are arranged, frame structures are formed by connecting adjacent supporting frames, at least three adjusting assemblies are arranged, and the adjusting assemblies are connected to the outer side ends of the supporting frames. The inner side end of each supporting frame is connected to the inner side end of the adjacent supporting frame. The problems thatthe lower end of the electric pole is fixed with a steel wire rope, the lower end of the electric pole is not fixed and potential safety hazards exist are solved. The frame structures are formed by adjacent supporting frames,
