Move the transformer body 4 downward. The transformer body 4 will enter the interior of the U-shaped seat 1. If it is in an outdoor environment, sleeve the connecting L-shaped plates 3 and the fixed tubes 19 on the surface of the L-shaped rods 27, and limit the connecting L-shaped plates 3 through the U-shaped rod 29, thereby protecting the transformer body 4. If it is in an indoor environment, it is determined whether to install the connecting L-shaped plates 3 according to the actual situation. The moving rods 31 and the fixed disks 32 can be used to install multiple U-shaped seats 1 and the transformer body 4.

[0033] Further, please refer to Figures 1-7 、 Figure 13 The adjusting mechanism includes a top plate 2. Fixed L-shaped plates 9 are fixedly connected to the centers of both the left and right sides of the top plate 2. Electric telescopic rods 11 are inserted into both the left and right sides of the U-shaped seat 1. The tops of the electric telescopic rods 11 are fixedly connected to one side of the adjacent fixed L-shaped plates 9. T-shaped plates 10 are fixedly connected to both the left and right sides of the bottom of the top plate 2 near the bottom. The T-shaped plates 10 are located in the inner cavities of the adjacent T-shaped grooves. First threaded holes are opened at both the left and right sides of the U-shaped seat 1 near the top. A number of second threaded holes are opened on one side of the fixed L-shaped plates 9. Bolts 12 are commonly threadedly connected to the inner cavities of the adjacent second threaded holes and the first threaded holes. A number of fixed rods 13 are fixedly connected to both the front and rear sides of the bottom of the top plate 2 near the bottom. Springs 14 are fixedly connected to the bottoms of the fixed rods 13. Connecting rods 15 are fixedly connected to the bottoms of the springs 14. Fixing plates 16 are fixedly connected to the bottoms of the connecting rods 15. Vertical rods 17 are fixedly connected to the bottoms of the fixing plates 16. Rings 18 are fixedly connected to the bottoms of the vertical rods 17;

[0034] A T-shaped rod 5 is fixedly connected to the center of the top of the top plate 2. One end of the T-shaped rod 5 away from the top plate 2 is fixedly connected with a U-shaped block 6. A percussion rod 7 is hinged in the inner cavity of the U-shaped block 6. Elastic columns 34 are fixedly connected to both sides near the top of the top plate 2. The top ends of the elastic columns 34 are fixedly connected with percussion plates 8.

[0035] Rotate the bolt 12 to remove the bolt 12 from the fixed L-shaped plate 9. The electric telescopic rod 11 drives the top plate 2 to move upward through the fixed L-shaped plate 9, and rotate the electric telescopic rod 11. The electric telescopic rod 11 drives the top plate 2 to rotate through the fixed L-shaped plate 9, and move the top plate 2 out of the top of the U-shaped seat 1, so as to facilitate placing the transformer body 4 inside the U-shaped seat 1. Then place the top plate 2 on the top of the U-shaped seat 1 again. The setting of the ring 18 can sort and limit the wires connected to the transformer body 4. If an animal climbs on the top of the top plate 2, the electric telescopic rod 11 drives the top plate 2 to move up and down. The top plate 2 drives the percussion rod 7 to swing up and down. The percussion rod 7 strikes the percussion plate 8 to make a sound to drive away the animal.

[0036] Working principle: When the device starts to work, the operator hoists and moves the transformer body 4 to the top of the U-shaped seat 1 through a crane. The top plate 2 is removed from the top of the U-shaped seat 1 in advance, and the T-shaped block 20 is aligned with the T-shaped groove at the top of the U-shaped seat 1. The transformer body 4 is slowly moved downward, and the T-shaped block 20 is moved into the T-shaped groove. Then the operator takes out the limit threaded ring 26 and rotates the limit threaded ring 26 to the outer edge near the bottom of the connecting threaded rod 21, thereby preliminarily limiting the transformer body 4. Then the operator starts the electric telescopic rod 11 through an external power supply. The electric telescopic rod 11 drives the top plate 2 to move through the fixed L-shaped plate 9, and at the same time rotates the top plate 2 and rotates the top plate 2 back to the top of the U-shaped seat 1. The T-shaped plate 10 at the bottom of the top plate 2 is aligned with the T-shaped groove at the top of the U-shaped seat 1. At this time, the electric telescopic rod 11 drives the top plate 2 to move downward through the fixed L-shaped plate 9. The top plate 2 drives the T-shaped plate 10 to move downward, and the T-shaped plate 10 limits the T-shaped block 20. The operator takes out the bolt 12, passes the bolt 12 through the fixed L-shaped plate 9 and rotates it to the surface of the U-shaped seat 1, thereby further limiting the transformer body 4. If it is in an outdoor environment, the operator sleevs the fixed pipe 19 on the surface of the L-shaped rod 27 in advance. The fixed pipe 19 drives the connecting L-shaped plate 3 to move. Several connecting L-shaped plates 3 are located on the front and back sides of the transformer body 4. Take out the U-shaped rod 29, and the U-shaped rod 29 penetrates through the adjacent limit pipe 28, then the connecting L-shaped plate 3 can be limited. The connecting L-shaped plate 3 has a protective effect on the transformer body 4. The limit threaded rod 36 and the rotating disk 35 can limit the fixed pipe 19 to prevent the fixed pipe 19 from detaching from the surface of the L-shaped rod 27. If it is in an indoor environment, it can be adjusted according to actual needs whether to install the connecting L-shaped plate 3. At the same time, after the transformer body 4 is installed inside the U-shaped seat 1, if it is necessary to connect multiple U-shaped seats 1 and the transformer body 4, move the movable rod 31 back and forth. The movable rod 31 drives the fixed disk 32 to move. Screws are installed through the threaded holes on the surface of the fixed disk 32, thereby limiting it and realizing the connection of multiple U-shaped seats 1 and the transformer body 4. When the transformer body 4 needs to access the circuit, pass the circuit through the adjacent ring 18. The ring 18 is connected through the vertical rod 17, the fixing plate 16, the connecting rod 15 and the spring 14. Due to the setting of the spring 14, the position of the ring 18 can adjust its own height according to the position of the circuit, which is convenient for subsequent use and can also achieve the effect of sorting and limiting the circuit. If the device is installed outdoors, the bolt 12 does not need to be installed at the fixed L-shaped plate 9. When an animal climbs on the top of the device, start the electric telescopic rod 11. The electric telescopic rod 11 drives the top plate 2 to move up and down through the fixed L-shaped plate 9. The top plate 2 drives the T-shaped rod 5 to move up and down. The T-shaped rod 5 drives the knocking rod 7 to swing up and down through the U-shaped block 6. The knocking rod 7 knocks on the knocking plate 8 to make a sound, thereby driving away the animal. At the same time, if the transformer body 4 does not need to be protected, the transformer body 4 can be placed alone on the ground.Rotate the movable L-shaped plate 23, and the movable L-shaped plate 23 drives the connecting threaded ring 22 to rotate. The connecting threaded ring 22 rotates on the surface of the connecting threaded rod 21, so that the position height of the universal wheel 25 can be adjusted. When the universal wheel 25 contacts the ground, it can support the transformer body 4 and also help the transformer body 4 to move, improving the practicality of the device.
