The shaft drives the fan blades to rotate, thereby generating wind force, accelerating the air circulation inside the cold storage and avoiding uneven temperature inside the cold storage. The bearing of the fan frame 902 is installed in the protective frame 901. When the protective frame 901 is fixed to the fixing frame 9, it is 135° obliquely pointed to the cold storage ground with the fixing frame 9, which is convenient for enhancing the working stability of the fan frame 902. The protective frame 901 is 2000mm-2200mm from the ground. The human body height is generally below 2 meters, which is conducive to avoiding overlap with the activity space of the staff, increasing the activity space of the staff and saving the internal space of the cold storage.
