Compensation device for spliced sub-mirror board of radio telescope

The invention discloses a compensation device for spliced sub mirror panels of a radio telescope. The compensation device comprises a connecting flange, a panel supporting rod, a deflection ball head, a deflection adjusting seat, a deflection adjusting rod, a deflection fixing seat, a translation adjusting rod, a translation locking screw rod and a translation locking nut. Relative deformation of the unit panels is generated by adjusting the panel supporting rods to jack or pull the spliced sub mirror panels of the radio telescope at the joints of the panel supporting rods, and the effect of adjusting the surface shape of a single panel is achieved. The deflection adjusting seat is pushed by adjusting the deflection adjusting rod, so that the panel can rotate at a two-dimensional angle in the space; one-dimensional translation of the panel in the space is realized by adjusting the relative position of the translation adjusting rod and the translation locking screw rod; and one end of the translation locking s
