The utility model discloses a be applied to umbelliform cooling member of ever -frozen ground area power transmission line shaft tower, including installing the umbelliform metal bracket frame in steel pipe shaft tower bottom, solar cell panel installs and installs porous ventilation panel at umbelliform metal bracket frame to sunny side, umbelliform metal bracket frame back of the body sunny side, and mechanical ventilation equipment installs on porous ventilation panel, and battery and solar energy control system install at umbelliform metal bracket frame insidely, the photovoltaic effect who utilizes solar panel provides the power supply for the inside mechanical ventilation equipment of umbelliform bracket to make the steel pipe shaft tower receive the influence of convection current rather than the attachment point of metal pile foundation down and the heat transfer reduces because the steel pipe pole tata body itself receives the heat radiation and transmits the thermal current of ever -frozen ground, to effective cooling of the defeated power wire tower base in ever -frozen ground district, the artificial upper limit of improvement ever -frozen ground, reinforcing foundation's stability and foundation bearing capacity reduce the column foot and melt heavy possibility and engineering freeze injury.
