Transformer refueling device for water conservancy and hydropower

The transformer refueling device comprises a supporting seat and an oil tank, a sliding groove is formed in the outer wall of the supporting seat, a threaded rod is rotationally connected to the inner wall of the sliding groove, one end of the threaded rod penetrates through the supporting seat and is fixedly connected with a rotating disc, and a sliding block is fixedly connected to the outer wall of the oil tank; and the sliding block is slidably connected to the interior of the sliding groove, the inner wall of the sliding block is in threaded connection with the outer wall of the threaded rod, and the inner wall of the oil tank communicates with a hose. Through the arrangement of structures such as a threaded rod and a limiting seat, the device is more convenient to use, a rotating disc drives the threaded rod to rotate, a sliding block drives an oil tank to ascend, when the limiting seat is slightly higher than a transformer, the oil tank stops, and then an oil filling pipe rotates around the connecting
