In addition, when the power station is not maintained, the sealing cover 4 seals the oil unloading pipe 1 to prevent oil leakage and prevent oil from overflowing when boiling.

[0030] Key References Figure 2 and Figure 5 The top of the oil unloading pipe 1 is provided with an oil unloading pipe joint 5, and the oil unloading pipe joint 5 can be connected to the oil unloading pipe 1 through a clamp 6 to ensure a sealed connection; the sealing cover 4 is sealed and matched on the top of the oil unloading pipe joint 5, and the top of the oil unloading pipe 1 is detachably installed on the power station through the oil unloading pipe joint 5, so that the oil unloading pipe 1 is stored in the power station. When in use, the top of the oil unloading pipe 1 is removed to perform the oil discharge operation. After the operation is completed, the oil unloading pipe joint 5 is fixed to the power station. Specifically, a connecting piece 7 is provided on one side of the power station, and an elastic buckle is provided on the outer periphery of the oil unloading pipe joint 5. The elastic buckle is engaged with the connecting piece 7 to realize the detachable connection between the oil unloading pipe joint 5 and the power station, and the connecting piece 7 can be fixed on the outer frame of the power station or on the components inside the outer frame, such as the heat dissipation device of the power station.
