Efficient heat dissipation generator protection device

The invention relates to the technical field of power generation equipment, and discloses an efficient heat dissipation generator protection device which comprises a generator, the generator further comprises an overheat protection device, the overheat protection device comprises a cooling structure and a pressurization structure, a protection box is arranged on the outer side of the generator, and vortex tubes are fixedly connected to the two sides of the protection box. The air inlet pipes are fixedly connected to the inner walls of the two sides of the protection box, the partition plates are fixedly connected to the inner sides of the air inlet pipes, the air inlet grooves are formed in the partition plates, cold air enters the air inlet pipes and then enters the air inlet cylinders through the air inlet grooves in the partition plates, the air inlet cylinders cannot be pushed when the density of the cold air is low and the pressure is small, and the air inlet cylinders retract into the air inlet pipes; w
