Ventilation device of energy storage power supply

The invention relates to a ventilation device, in particular to a ventilation device of an energy storage power supply. The ventilation device of the energy storage power supply can intensively guide wind and blow the wind to a power supply assembly for ventilation and heat dissipation, and improves the ventilation and heat dissipation efficiency. A ventilation device of an energy storage power source comprises a shell, a cover plate, fans and the like, the cover plate is fixedly connected to the top of the shell, and the fans used for conducting ventilation and heat dissipation on a power source assembly are fixedly connected to the middles of the left side and the right side of the shell in a penetrating mode. When the power supply assembly is used every time, a rotating wheel is twisted to drive a lead screw to rotate forwards, a sliding block drives shielding cloth to move inwards to a proper position, then fans on the left side and the right side are started, the fan on the left side blows air out, the s
