The invention discloses a turbine circulating wind power generator, comprising an engine body, a plurality of side-stream fan assemblies, a turbine power generation assembly, and a top cover, wherein the engine body is provided with a wind chamber which has an upper opening and a lower opening; each side-stream fan assembly comprises a side-stream fan blade and a spherical fan blade, a connection rod is connected with the side-stream fan blade and extends upwards, and the spherical fan blade is connected with the connection rod and located outside the upper opening of the wind chamber; the turbine power generation assembly is arranged in the wind chamber and provided with a power generator and a turbine fan blade; and the top cover is arranged at the top end of the engine body and located above the upper opening of the wind chamber, and an interval is arranged between the top cover and the top end of the engine body so that the up flow in the wind chamber can be radially blown from the upper opening to the spherical fan blade. The power generator can form wind circulation to enhance the power generation efficiency.
