Description

[0001] The invention belongs to the technical field of transformers, and in particular relates to a transformer waste storage device capable of automatically draining oil and an oil draining method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] During the disassembly process of the returned oil-immersed transformer, the disassembled components such as winding coils and silicon steel sheets are generally classified and placed in a closed storage device. However, the winding coils and silicon steel sheets will gradually leak oil during storage. When the storage device is made of non-wood materials, the oil seeping from the winding coils and silicon steel sheets will accumulate at the bottom of the storage device and cannot be discharged, thereby soaking the winding coils and silicon steel sheets, making these components unable to be recycled; when the storage device is made of non-wood materials, oil leakage may occur during the transportation and transfer of the storage device, thereby polluting the ground.

[0004] In summary, the prior art does not recover the leaked oil generated by the dismantled components of the returned oil-immersed transformer, thereby causing waste of resources or damage to the performance of the dismantled components. Summary of the invention

[0029] like Figure 3 As shown, the lifting mechanism 4 includes a first connecting rod 41, a limit block 42 and a first guide rod 43; the limit block 42 is a hollow structure and is fixed on a support seat, and the support seat is fixed on the bottom of the box body 1; according to Figure 3 It can be seen that the support seat includes a column 8 and a connecting plate connected thereto.
