The utility model discloses a stationary blade drive regulator for a blast furnace gas over-bottom pressure turbine power generation device and belongs to the field of energy power application. The stationary blade drive regulator for the blast furnace gas over-bottom pressure turbine power generation device is simple in structure, convenient and quick to repair, reliable in use and capable of effectively preventing gas and liquid from being mixed and preventing a spherical shaft sleeve from stretching and retracting in the axial direction. The stationary blade drive regulator comprises an outer cavity, a hydraulic oil cylinder, a piston rod and a spherical shaft sleeve. The piston rod is connected with the hydraulic oil cylinder, one end of the spherical shaft sleeve is fixedly connected with the outer cavity, the hydraulic oil cylinder is connected with the outer cavity through a support, the stationary blade drive regulator further comprises a sealing mechanism and a sealing ring, a high-temperature medium flows into the spherical shaft sleeve through the outer cavity and is sealed through the sealing mechanism, the high-temperature medium is prevented from making contact with high-pressure hydraulic oil, and the phenomenon of mixing gas and liquid is eradicated. The requirement for the swing angle of a swing cylinder can be met through a hinge mechanism, and the spherical shaft sleeve is prevented from stretching and being compressed in the axial direction.
