Mechanical seal shaft end engine oil sealing device

The invention discloses a mechanical sealing shaft end engine oil sealing device, and relates to the technical field of mechanical sealing shafts. The device comprises a box body, a sealing ring and a fixing disc, a mounting disc is fixedly connected to the interior of the box body, a pressure sensor is arranged in the mounting disc, the sealing ring is arranged in the mounting disc, a first oil injection cavity and a second oil injection cavity are formed in the box body, and the fixing disc is fixedly connected to the interior of the box body. When the pressure sensor detects that engine oil in the oil storage cavity is lost, the electromagnet is powered on, the sealing plate is driven by the driving assembly to move, so that the engine oil enters the oil storage cavity and is in tight contact with the sealing ring after expanding with the telescopic disc, and when the pressure sensor detects that the engine oil in the oil storage cavity is saturated, the telescopic disc is driven to rotate. The electromagn
