The invention relates to a novel medium- and high-attitude kite power generation device which mainly comprises umbrella kites, high strength kite ropes, kite balancers, kite take-up and pay-off devices, a floor holder, a rotary disk, telescopic support legs, telescopic rotary bars, an elliptical limit plate, a crossed gear and a power generator. The umbrella kites filled with certain helium or hydrogen rise up in air and are connected with the telescopic rotary bars through the high strength ropes. The telescopic rotary bars are capable of driving the rotary disk to rotate. The rotary disk transmits rotation to the crossed gear through a central shaft so as to drive the power generator to generate power. The novel medium- and high-attitude kite power generation device uses medium- and high-attitude wind to achieve wind power generation, and is high in generating power, low in noise, high in safety factor, simple to manufacture and mount, and easy to repair and control.
