The top surface of the mounting seat 9 has two mirror-symmetrical guide grooves 10. Each guide groove 10 has a connecting block 13 directly above it.

[0021] Multiple equally spaced mounting holes 21 are vertically inserted through both sides of the top surface of the base 7. An internally threaded tube 22 is axially inserted into each mounting hole 21. A pad 8 is fixed to the bottom surface of the multiple internally threaded tubes 22.

A pad 22 is fixed to the end of the multiple positioning posts 24 on the same side. The pad 22 is fixed to the top surface of the mounting base 9.

[0022] To cool the transformer body 1 during operation and to filter and collect large debris on the heat dissipation fins 14, a heat dissipation fin 14 is fixed on each of the front and rear sides of the transformer body 1. Each heat dissipation fin 14 has a groove 16 on its top surface and a fixing block 15 on each side of the bottom surface of the groove 16. The fixing block 15 is fixedly connected to the transformer body 1. A collection groove 18 is movably connected inside the groove 16. A vent hole 1 is vertically penetrating the bottom wall of the collection groove 18. A second vent hole is provided at the lower opening of the groove 16.

[0023] By setting a base 7 on the bottom surface of the transformer body 1, movably connecting a support block 11 on the bottom surface of the base 7, telescopically connecting a roller 19 in the storage groove 31 on the bottom surface of the support block 11, and setting a guide groove 10 on the top surface of the installation, the speed of the transformer body 1 descending can be changed by adjusting the bolt 2 6, thereby buffering the vertical vibration of the transformer body 1 during installation, preventing the transformer body 1 from descending too quickly and generating vibration, which could damage the components inside the transformer body 1.

[0024] Working principle: In use, the transformer body 1 is first hoisted onto the top surface of the mounting base 9 using the lifting lug 2, so that the roller 19 is installed in the guide groove 10 on the top surface of the base 7. When the transformer body 1 descends, the spring 33 and the telescopic rod 32 buffer the downward trend of the transformer body 1. Then, the roller 19 moves the transformer body 1 so that the internal threaded tube 22 is aligned with the mounting hole 21. Then, the two bolts 5 are rotated concentrically, so that the base 7 slowly descends until the pad 8 abuts against the bottom surface of the base 7, and the internal threaded tube is inserted into the mounting hole 21. At the same time, the support block 11 will move upward until the roller 19 moves out of the guide groove. The transformer body 1 rises up, and the top surface of the support block 11 abuts against the bottom surface of the base 7. Then, bolt 2 6 is installed into the internal threaded pipe 22 to fix the base 7 onto the mounting seat 9. At this time, after the transformer body 1 starts, the heat dissipation fins 14 on both sides of the transformer body 1 can effectively prevent the internal temperature of the transformer from becoming too high. Then, the large impurities are filtered through the groove 16 with through groove 17 on the top surface of the heat dissipation fins 14. The large impurities will fall into the collection groove 18, which makes it easier to prevent larger impurities from entering. When the collection groove 18 is full, the collection groove 18 can be directly pulled out from the groove 16 by the handle to clean the large volume impurities collected in the collection groove 18.
