Photovoltaic two-shaft sun tracking structure

The utility model discloses a photovoltaic two-shaft sun tracking structure, relates to a solar tracking structure which comprises a supporting frame mechanism and a sun tracking supporting device. The supporting frame mechanism comprises a photovoltaic panel bracket and a supporting reinforcing beam assembly. The supporting reinforcing beam assembly comprises a plurality of transverse main beams and a plurality of longitudinal main beams. The transverse main beams and the longitudinal main beams are connected to form a planar structure. A connection part of each transverse main beam and longitudinal main beam is provided with two clamping plates which are respectively arranged at two sides of the planar structure so as to clamp the connection part of the transverse main beam and longitudinal main beam. The corresponding positions of the clamping plates, the transverse main beams and the longitudinal main beams are provided with bolt jacks, bolts are inserted into the bolt jacks, and the two clamping plates a
