AI Technical Summary

Technical Problem

In the existing technology, transformer oil replenishment requires manual lifting of the container to a high place, which increases labor intensity and lacks convenient conveying and injection devices.

Method used

Design a transformer oil injection mechanism that uses a pump to extract oil from a container and transport it to a higher position. A geared motor drives the bundle tube assembly to rotate, enabling the unwinding and rewinding of the outlet tube. This facilitates the insertion of the top of the outlet tube into the oil conservator. Combined with a winding disc, protective tube, and through-hole structure, automatic oil delivery is achieved.

Benefits of technology

This technology enables the automatic delivery of transformer oil to the oil tank without the need for manual lifting of the container, reducing labor intensity and improving replenishment efficiency and safety.

Abstract

The utility model relates to the technical field of transformers, in particular to a transformer oil injection mechanism which comprises a winding disc, a protection pipe and a through hole, an infusion pump is installed in the winding disc through an installation frame, a driving assembly is arranged at the top of the winding disc, and the driving assembly comprises a first protection box fixed to the top of the winding disc through a bolt. An electric power storage box is arranged in the first protection box, a second protection box is arranged at the top of the first protection box, and a speed reduction motor is mounted in the second protection box through a mounting frame; a beam tube assembly is arranged at the top of the second protection box and comprises an L-shaped connecting rod fixed to an output shaft at the top of the gear motor through a bolt. The speed reduction motor works to drive the L-shaped connecting rod to rotate, the liquid outlet pipe wound on the outer side of the winding disc is loosened, a worker can conveniently insert a taper pipe at one end of the liquid outlet pipe into an oil filling opening of the oil conservator, the infusion pump works to pump the transformer oil in the container into the oil conservator, and the container containing the transformer oil does not need to be lifted up.
