The invention relates to the technical field of snow removing tools, in particular to an accumulated snow removing tool for transformer substation primary equipment. The accumulated snow removing tool comprises a trolley body and an electric fan. The trolley body comprises a trolley base plate, wheels and a hand-pushed rack. A detachable seat plate is fixedly installed on the middle of the trolley base plate. The electric fan is fixed to the seat plate. A cover is arranged outside the electric fan. The bottom of the cover is fixed to the top of the seat plate. The air outlet end of an air outlet pipe of the electric fan stretches out of the cover and is connected with an air duct. According to the accumulated snow removing tool, the structure is reasonable and compact, using is convenient, the electric fan is fixed to the trolley body, an operator can control the tool to advance and retreat by pushing and pulling the hand-pushed rack, and the working intensity is relieved; a synthetic oil fuel power source of a backpack snow removing machine is replaced by an electric power source, and thus the safety is improved; and in addition, the accumulated snow removing tool can be directly connected with a power source arranged in a transformer substation and used continuously and has the characteristics of being safe, capable of saving labor, simple, convenient to use and durable.
