[0022] The technical solution of the utility model is further described below with specific embodiments, but the protection scope of the utility model is not limited to the following embodiments.

[0023] Implementation method 1: Figure 1 , 2 As shown, the drop-proof voltage transformer includes a transformer body 1, a transformer bracket 2 detachably fixed below the transformer body 1, and a clamp mechanism 3, wherein the clamp mechanism 3 includes a movable clamp 301 and a fixed clamp 302 welded to the transformer bracket 2 as a whole on the inner side of the transformer bracket 2, and the movable clamp 301 and the fixed clamp 302 are connected and fixed by long bolts 4 and nuts 5; the movable clamp 301 and the fixed clamp 302 both include a U-shaped frame 31, and an arc-shaped clamp claw 32 welded in the notch of the U-shaped frame 31, bolt holes 311 are provided on both sides of the U-shaped frame 31, and teeth 312 are milled on the edges of the upper and lower groove walls in the central part of the U-shaped frame 31, and steel nails 313 are welded on the bottom of the groove in the central part of the U-shaped frame 31, and the inner surface of the arc-shaped clamp claw 32 is formed with a plurality of laterally extending stop edges 321.

[0024] Implementation 2: The transformer support 2 of the drop-proof voltage transformer includes two beams 201 and a beam connecting frame 202. Both beams 201 include an H-shaped section at the front and a T-shaped section at the middle and rear. The H-shaped section is welded to the U-shaped frame 31 after being buckled into the fixed clamp 302. A plurality of reinforcing ribs 23 are welded between the cross beam 21 and the vertical beam 22 of the T-shaped section, and bolt holes 231 are opened on the reinforcing ribs 23. The remaining structures and components are as described in Implementation 1 and will not be described again.

[0025] Embodiment 3: The anti-fall voltage transformer of the present invention has a rubber cushion 24 with a thickness of 8 mm attached to the cross beam 21 of the T-shaped section, and a through long slot fixing hole 25 is provided on the cross beam 21 and the cushion 24. The remaining structures and components are as described in Embodiment 1 and will not be described again.

[0026] Embodiment 4: The long bolt 4 of the drop-proof voltage transformer passes through the bolt holes 231 on each reinforcing rib 23, the fixed clamp 302 and the bolt hole 311 on the movable clamp 301 in sequence, and is fastened to the back side of the U-shaped frame 31 of the movable clamp 301 by the nut 5. The remaining structures and components are as described in Embodiment 1 and will not be described again.

[0027] Embodiment 5: The transformer body 1 of the drop-proof voltage transformer passes through the body bolt hole 101 on the base of the transformer body 1, the buffer pad 24 and the long slot fixing hole 25 on the beam 21 in sequence through the body bolt 11, and is fastened from the back side of the beam 21 by the body nut 12.

[0028] When using: Figure 3 As shown, the outer wall of the pole tower is held from both sides of the pole tower by using movable clamps and fixed clamps; the long bolts are passed through the bolt holes on the reinforcing ribs, the bolt holes on the fixed clamps and the movable clamps in turn, and are fastened on the back side of the U-shaped frame of the movable clamps through nuts. During the fastening process, the front end of the steel nail penetrates into the shallow layer of the pole tower concrete, and then the teeth bite the outer wall of the tower pole. The arc-shaped claws open to both sides under extrusion and embrace the pole tower, and the stop edges are embedded in the shallow layer of the pole tower concrete, completing the fixation of the bracket on the pole tower. The bracket crossbeam is used for bearing weight, and the fastened long bolts, reinforcing ribs and movable clamps also play a role of auxiliary bearing weight, so as to more firmly stop and fix the pole tower and prevent the bracket from falling off. Then place the transformer body on the buffer pad of the beam, pass the body bolts through the body bolt holes on the transformer body base, the buffer pad and the long slot fixing holes on the beam in sequence, and use the body nut to tighten from the back side of the beam. The transformer is fixed and installed. The vibration generated during the operation of the transformer body can be largely absorbed by the rubber buffer pad, reducing the amount of vibration transmitted between the body screw, the body nut, and the long bolts and nuts, thereby preventing the bolts from loosening.

[0029] The anti-fall voltage transformer overcomes the risk of falling caused by the existing voltage transformer installed on the pole. Its complete set of matching pole tower fixing structure optimizes the clamp structure so that it can fix the pole tower more firmly to prevent falling and stop retreat. At the same time, the connection strength between the supporting bracket and the clamp mechanism is strengthened, and the vibration generated by the operation of the transformer is buffered and reduced to be transmitted to each bolt fixing position, so that the transformer and the bracket, as well as the bracket and the pole tower are firmly fixed, effectively preventing the transformer from falling and being damaged from a high altitude, and ensuring the safety of the area below the pole tower.
