Photovoltaic balloon power generation device

The invention provides a photovoltaic balloon power generation device, and belongs to the field of solar photovoltaic power generation. The upper part of the balloon body is a hemisphere made of a material with a specific refractive index, the lower part of the balloon body is a cambered surface, the outer side of the balloon body is provided with a solar thin film battery, the balloon body is filled with helium which is pollution-free and low in density, so that the balloon can rise to the sky, and four lifting rings which are distributed at equal intervals are arranged in the middle of the outer side of the balloon body. The four lifting ropes are fixedly connected with the balloon body and the control storage module, an early warning air valve is designed on the surface of the balloon body, when the air pressure in the balloon body reaches a threshold value under the high temperature condition, a proper amount of internal air is passively exhausted, the fixed electric wire is connected with the control sto
