The utility model relates to the technical field of electric power auxiliary devices. The utility model further discloses an electric power plant generator automatic heat dissipation device capable ofachieving electric automatic adjustment. Bottom plate, a generator body and a protective cover are fixedly mounted at the top of the bottom plate. The protection cover is located on the outer side ofthe generator body, a liquid supply box is fixedly installed on the right side of the top of the protection cover, the left side of the liquid supply box fixedly communicates with a connecting pipe,an electromagnetic valve is fixedly installed on the connecting pipe, the other end of the connecting pipe fixedly communicates with a water pump, and the water pump is fixedly connected with the topof the protection cover. The utility model discloses an electric automatic adjustment power plant generator automatic heat dissipation device. Under the action of the temperature sensor, the temperature in the protective cover is monitored in real time, the heat dissipation motor and the air conditioner are intelligently adjusted according to requirements, the problem that a large amount of electric quantity is consumed due to the fact that traditional heat dissipation is not ideal and long-time starting is conducted is solved, and therefore the effect of automatic heat dissipation adjustmentis achieved.
